Collective silence!No major domestic mobile phone manufacturers are ready to carry Huawei Hongmeng

After nearly 4 rounds of suppression, whether Huawei’s mobile phone business can stop the decline and seek opportunities to rise, Hongmeng system will take on a lot of responsibility in the future. In the words of Huawei executives, in addition to building Huawei’s own operating system and ecosystem, Hongmeng System must also buy time for Huawei’s hardware rise.

At 8 pm on June 2, Huawei officially announced the launch of a new generation of smart terminal operating systems and products with the new system. June 2 will be a highlight in Huawei’s development history.

Collective silence!No major domestic mobile phone manufacturers are ready to carry Huawei Hongmeng

From a potential point of view, if Hongmeng becomes famous in the first battle, US companies will not be able to cover the sky with one hand in the field of operating systems. The emergence of Hongmeng will end the history of domestic mobile phones without an operating system, and will also break the monopoly of Google and Apple. However, with the release of the Hongmeng system, the attitude of friends and businessmen made Huawei see the reality.

5 silent only 2 support

For Hongmeng to succeed, it needs not only various breakthroughs in technology, but also the number of users and the support of ecological partners to support it. , 5 remained silent, and only 2 expressed support. This is not good news for the upcoming release of Hongmeng.

It is understood that several domestic Huawei friends, although they have previously stated that they will not rule out companies that have further cooperation with Hongmeng, but when June comes, domestic companies such as Xiaomi and OV have adopted a silent response to whether they are compatible with Hongmeng. Attitude. Even from the previous development process, you can still see a trace of unfriendly atmosphere. For example, employees of a mobile phone manufacturer have publicly ridiculed the Hongmeng system on social platforms, and ZTE earlier has clearly rejected Hongmeng.

Opposite to the top 5 manufacturers are Honor and Meizu. These two manufacturers are supportive of Huawei Hongmeng. Meizu has previously stated that it has access to the Hongmeng ecosystem, but it is limited to its smart home business. Meizu mobile phones are still not compatible with the Hongmeng system, and the same is true of other manufacturers.

Honor upgrade Hongmeng OS system mobile phone model table

It is a little regrettable that compared with the other five mobile phone manufacturers, the strength of these two companies is still weaker. Although Meizu used to be a leader in the mobile phone industry, after several years of development, Meizu is now a different person, and Meizu is basically invisible in the ranking of market share. And Honor has just become independent from Huawei, and the chip supply chain and market share are slowly recovering. The addition of the two of them is only a drop in the bucket for Hongmeng’s goal of 300 million users.

I have to say that this is the reality. As Huawei executives said, creating a mobile operating system is only 1% complete, and the remaining 99% requires the joint efforts of all mobile phone manufacturers. It can be seen that how Huawei can make its peers recognize Hongmeng will be one of the difficulties in future work.

The reason why Xiaomi OV does not respond to Huawei Hongmeng OS for the time being

The reason why domestic manufacturers such as Xiaomi OV are waiting and watching, I personally think it may be because of the following points.

First of all, the Hongmeng OS system is still immature, and its immaturity is mainly in the application ecology. After all, the IOS ecology and Android ecology are often millions of apps, but the application ecology construction of Hongmeng OS is still in its infancy.

Secondly, although Hongmeng OS has been open sourced, and Huawei has donated the core foundation of Hongmeng OS, the Hongmeng OS system has not been open sourced to larger memory devices.

It is reported that the current Hongmeng OS is only open source to devices with memory below 128MB, and may open source to devices with memory between 128MB and 4G in the near future, and open source to devices with memory above 4G will be later.

Nowadays, smartphones often have more than 4G of memory, and even the memory is as high as 12G. Huawei does not open source, and domestic manufacturers such as Xiaomi OV naturally cannot respond immediately.

Once again, it is Fuchsia OS, an IoT operating system officially publicly available by Google on May 26.

As early as 2016, the magic secret code appeared on GitHub, and it was Google who was developing a new operating system called “Fuchsia”, which was built to enable cross-platform operation.

Since then, the operating system has been continuously improved, and Huawei, Xiaomi, OPPO, and Vivo have all contributed code to Fuchsia OS.

And Xiaomi OV has been deeply involved in the Android ecosystem for many years, so for them, I am afraid that Fuchsia OS is more intimate than Hongmeng.

Finally, because of Huawei.

For example, after Microsoft entered the hardware field, manufacturers such as Lenovo and Dell opposed it, because Windows is Microsoft, and Microsoft wants to sell Windows devices, which is equivalent to direct competition with manufacturers such as Lenovo and Dell.

Fortunately, Microsoft only makes high-end devices and competes directly with Apple. The purpose is to improve the quality of Windows devices, and the opposition from major manufacturers is a little less.

Today, Huawei’s situation is similar to Microsoft’s, because Hongmeng OS is Huawei, and Huawei itself builds mobile devices based on Hongmeng OS. Under such circumstances, domestic manufacturers such as Xiaomi OV naturally have to figure out Huawei’s mind.

The three giants officially entered the game

We see that Hongmeng’s partners come from the fields of home furnishing, travel, education, office, etc., including Midea, Supor, iFLYTEK, BOE, 360 and other companies, and they have joined Hongmeng’s “circle of friends”.

In the past few days, Gree also announced to join as a partner of Hongmeng. As an attempt of a domestic system, Hongmeng has also received support from many banks.

At present, three banks, Bank of China, China CITIC Bank (credit card), and China Guangfa Bank (credit card), have taken the lead in announcing access to the Hongmeng operating system.

Bank of China announced that, as a strategic partner of Huawei, combined with the functional characteristics of Hongmeng, it took the lead in launching the atomic service of “BOC Foreign Currency Cash Reservation”, laying out a new ecology of open banking scenarios, and actively exploring lightweight services. He also said that in the future, it will work with Huawei to continue to explore the new technologies and service methods brought by Hongmeng, and try to launch financial scene services based on “voice arousal” and “multi-terminal collaboration”.

China CITIC Bank stated in its announcement that using the HarmonyOS atomization service, customers do not need to download the APP, and can use the “China CITIC Bank” service card to apply for a China CITIC Bank debit card and check the progress. Through the simple operation mode, the convenience of user card application and progress inquiry is improved.

The official WeChat account of China Guangfa Bank credit card stated that Guangfa officially became the first member of Huawei’s Hongmeng operating system ecosystem. As the first credit card application in the banking industry to adapt to Hongmeng, the “Discover Wonder” app fully supports the localization of the operating system. GF Credit Card said that both in terms of underlying technology and products, GF Credit Card has worked closely with Huawei, and GF Credit Card is also one of the first banks to support Huawei Pay. ?

In addition to the above three banks, it is reported that many financial institutions are now testing the Hongmeng system. Many people in the bancassurance industry believe that from the perspective of financial institutions, combining the powerful functions and scalability of the Hongmeng system is conducive to launching more efficient products and services for users, and more financial institutions are expected to participate in the future.

Because of the open source nature of Hongmeng system, it is not only compatible with various terminal products, but also can be applied to the ecology of different scenarios. It is believed that with the arrival of the Hongmeng system, it may bring new changes to the financial industry such as banks.

Sometimes, for enterprises, in addition to considering commercial interests, there will also be a certain overall view, especially for related enterprises such as banks.

To what extent the Hongmeng system can develop, in addition to Huawei’s basic work, it is inseparable from the support of various companies.

Does China really need the Hongmeng system?

No, China doesn’t really need the Hongmeng system, what China needs is its own system.

CCell Renewables Partners with Vicor to Power New Coral Reef Growth

CCell Renewables is a marine natural science company that aims to restore and plant newcoral reefto curb coastal erosion and improve marine ecosystems. More than 70% of the world’s coastlines are eroding, 200 million people worldwide depend on the protection provided by coral reefs, and communities and livelihoods are at risk in many habitats around the world, new data shows.

The CCell reef planting system is based on the electrolysis of seawater, depositing calcium carbonate (limestone) on a large steel frame with anodes and cathodes (electrodes), giving new reefs early structure. This technology is a revolutionary breakthrough, it takes only 5 years to produce an incredible, solid limestone on which corals can grow, instead of hundreds of years. In addition, CCell uses renewable energy sources such as solar, wind and wave energy to power coral reef cultivation systems.

The output voltage of all these renewable energy sources varies widely depending on environmental conditions, which is a major problem in the electrolysis process. The limestone structures in which coral polyps grow must grow at optimal rates, be free of impurities, and have a strong molecular structure. The electrolysis process has to be precise, too slow and nothing will grow; too fast and the limestone can’t sustain. Therefore, distribution networks must be able to adapt widely to extremely challenging environments and operate with a high degree of controllability and accuracy.

distribution network

Considering the wide variation in input voltage specifications and the need to tightly regulate the potential difference (electric field) between electrodes within the “ideal range” of 1.2V to 4V, and drive a precisely calculated current through seawater. Therefore, Vicor recommends its factorial power architecture (FPA).

By decomposing the DC-DC function into two modules, the PRM regulator and the VTM current multiplier, the regulation and conversion of the distribution network can be optimized.

The PRM buck-boost regulator operates over a wide input voltage and uses a zero-voltage switching (ZVS) topology to achieve very high efficiency and power density. In addition, PRMs can be easily paralleled for higher power. The VTM is a fixed ratio (unregulated) resonant converter with very high current density. The PRM works closely with the VTM, with the PRM tightly regulating the voltage required by the reef, while the VTM handles the step-down switching and the current supplied to the electrodes.

“This complex and unique application has many continuously changing variables that require precise measurement and control to accelerate reef growth,” said Will Bateman, CEO of CCell. “With Vicor’s FPA, we now have a high-performance design. , believe it will greatly improve ecosystems and communities across the planet.”

CCell has always been committed to growing coral reefs around the world and is currently preparing a new 200-meter reef in Mexico.

Code is the weapon

On October 20, 2021, local time, the U.S. Department of Commerce announced new export controls aimed at restricting the sale of hacking tools to countries such as China and Russia. The subtext of the new US regulation is that “China is buying hacking tools to carry out cyber attacks”, but it turns a blind eye to the fact that the country is the world’s largest buyer, stockpiler and seller of cyber weapons. Cybersecurity experts believe the new U.S. measures are aimed at perpetuating its dominance in cyberattacks.

U.S. issues new export controls to limit sales of hacking tools to Russia and China

US media reported on October 21, 2021 that the US Bureau of Industry and Security (BIS) under the US Department of Commerce issued a new export control regulation aimed at curbing exports to countries such as China and Russia Hacking. Previously, the rule had been shelved for years. The rule, which will take effect in 90 days, will prevent U.S. companies from selling any hacking software and equipment to China, Russia, Vietnam and other countries unless they have a license from the Commerce Department’s Bureau of Industry and Security. The Commerce Department has previously imposed export controls on some tools that encrypt data. Under the new rules, U.S. officials will take a hierarchical approach to regulating “intrusion software” that helps users break into computer networks to monitor, steal data or damage systems.

The new rule prohibits the sale of hacking tools to governments and individuals in countries such as China, Russia and Yemen that have been identified as constituting so-called U.S. national security concerns, or countries facing a U.S. arms embargo, such as Venezuela, unless U.S. companies and their distributors obtain relevant license. The new rules also explicitly prohibit exports of a broad range of products to countries the U.S. deems sponsoring terrorism, such as Iran and North Korea, as well as embargoed countries such as Cuba.

But the new rule also opens up backdoors, such as those involving sales to U.S. allies, sales to private individuals, and in some cases tools to probe cyber defenses or consulting services to hacked organizations . Companies selling hacking tools to Israel, Saudi Arabia, Bahrain, Taiwan and the United Arab Emirates will require licenses, but U.S. companies are free to sell such software to those countries that use the tool for defense purposes, the Commerce Department said. s individual. The new rules also allow U.S. Internet companies to sell tools that detect software vulnerabilities and provide consulting services to help combat hacking in most unrestricted countries.

Global Cyber ​​Weapons Market Grows Rapidly

According to the “2019-2027 Global Cyber ​​Weapons Market Forecast” released by the American consulting service company inkwood in 2019, the global cyber weapons market was worth $45.12 billion in 2018 and is expected to generate approximately $65.13 billion in net income by 2027, with a compound annual growth rate. The rate was 4.17%. The global cyber weapons market is primarily driven by the following five factors: Rising demand for advanced cyber weapons, increasing defense spending, commitment of multiple agencies to invest in identifying zero-day vulnerabilities, expansion of traditional weapons manufacturing companies in cyber security business, cyber The number of questions increases.

The global cyber weapons market is divided into four geographic regions: North American cyber weapons market (US and Canada), European cyber weapons market (UK, France, Germany, Italy, Spain and Rest of Europe), Asia Pacific cyber weapons market (China, India) , Japan, Korea, Australia, New Zealand and Rest of Asia Pacific), Rest of World (Latin America, Middle East and Africa).

Geographically, North America accounted for the largest revenue share of the market in 2018. In addition to the increase in defense spending in North America, the growing demand for cyber weapons is mainly due to the growing number of cyber attacks against the United States and Canada.

Rising internet penetration, increasing mobile data usage and the use of BYOD (bring your own device), cyber-attack cases in the Asia-Pacific region are increasing at a significant rate, making the Asia-Pacific region projected to be the fastest growing region for cyber weapons regional market. Countries such as India are seen as major markets with huge investments in defense.

Vulnerabilities are a favorite in the cyber weapons market

The biggest change in the vulnerability market in recent years has been the influx of government funding, especially the huge US government investment. According to the Center for Strategic and International Studies in Washington, the U.S. tops the vulnerability buying and selling list, followed by Israel, the U.K., Russia, India and Brazil. North Korea also has a piece of the market, along with some Middle Eastern intelligence agencies.

In fact, a 2013 report by the European Centre for Information Security and Policy stated that the NSA entered into a one-year contract with the French company VUPEN in September 2012 to subscribe to VUPEN as required by the US Freedom Act. Binary Analysis and Exploits Service. This allows the NSA to use software backdoors as well as zero-day exploits.

In 2015, the U.S. Bureau of Industry and Security unveiled a plan to put restrictions on hacking into a global arms trade treaty known as the Wassenaar Arrangement (WA). The Wassenaar Agreement, an export restriction agreement signed by 42 countries, restricts the export of ammunition and weapons such as tanks, missiles and firearms, as well as “dual-use goods and technologies” such as nuclear fuel rods. In a 2013 addendum, the agreement sought to regulate cyber-attack tools, known as “intrusion software.” But countries interpret the agreement and implement it in their laws differently. The Wassenaar Agreement excludes South Asia (including India, Indonesia, and China), most of South America (the only country in the agreement is Argentina), most of Africa (the only country in the agreement is South Africa), and West Asia ( including Israel, Iran, etc.). While Israel operates a similar licensing program for the export of hacking tools, the Israeli government allows cellphone spyware developer NSO to sell its cellphone surveillance software to many foreign governments. Dozens of countries, including India, Saudi Arabia, and Germany, purchase products from NSO to monitor “political enemies.”

  

Wassenaar Agreement

Key Players in the Global Cyber ​​Weapons Market

Kaspersky Lab, Boeing, McAfee (acquired by Intel Security), Cisco Systems, Northrop Grumman, Lockheed Martin, Airbus, AVAST Software, Raytheon, Mandiant (acquired by FireEye acquisition), BAE Systems, AVG Technologies, General Dynamics, and Symantec Corporation are some of the prominent players in the global cyber weapons market.

In recent years, private cybersecurity companies in the United States, Israel and other countries have sprung up, providing a large number of cyber weapons for state-level cyberattacks, giving birth to the new concept of Private Sector Offensive Actor (PSOA), reflecting the importance of cyberattacks. privatization trend. Israel-based NSO Group is the poster child for the privatization of cyber attacks. NSO has developed an app called Pegasus (Pegasus), which is sold to government law enforcement agencies in India, Argentina, Saudi Arabia and other countries. The University of Toronto found more than 100 cases of misuse of NSO technology.

Countries such as the United States and Israel have been the main sellers of hacking technology and cybersecurity products in the international market. According to comprehensive public information, as of October 18, 2021, there were approximately 59 private cybersecurity companies in the world participating in national-level offensive cyber operations (see the table below for some companies), of which US companies topped the list, with as many as 15 , Germany ranked second, with 5 companies on the list, and Israel and Russia ranked third, both with 4 companies. Most of these companies offer software implants and intrusions, including zero-day exploits, exploit frameworks, security bypass techniques, communication interception products, and more.

The United States has the world’s largest cyber ‘nuclear arsenal’

Cyber ​​weapons are comparable to nuclear weapons, biological and chemical weapons, and may cause serious damage to the global infrastructure and the normal production and life of various countries. In 2015, Assange, the founder of WikiLeaks, revealed that the United States has developed as many as 2,000 kinds of cyber weapons, making it the world’s number one cyber weapon power. By building the world’s largest cyber arsenal comparable to nuclear weapons, the U.S. military and intelligence agencies have triggered a global cyber arms race and directly threatened global cyber security.

On May 12, 2017, the “WannaCry (Want to Cry)” ransomware broke out around the world, affecting more than 150 countries and regions, more than 100,000 organizations and institutions, and more than 300,000 computers, with a total loss of more than 50 billion yuan. An important reason why the “WannaCry” ransomware has caused serious losses is that the “Eternal Blue” cyber weapon developed by the National Security Agency has flowed into the civilian population and is used by hackers to make the ransomware “worm-like” spread. Microsoft President and Chief Legal Officer Smith publicly accused the National Security Agency of being unshirkable in the ransomware incident, and even compared the “theft of the cyber arsenal” to the theft of the Tomahawk missile.

The cyber weapon “Eternal Blue” developed by the National Security Agency is just one of many cyber weapons used by the “Equation” group under the National Security Agency. On April 14, 2017, the hacker group “Shadow Brokers” disclosed the extremely destructive network attack tools used by a large number of “Equation Group” including “Eternal Blue”, using these tools, A computer can be hacked as long as it is connected to the Internet, just like “WannaCry”, which can cause serious damage overnight.

  

“Equation” hacker group with NSA background

In 2019, U.S. media widely reported that U.S. cybersecurity firm Symantec found that Chinese intelligence agencies had obtained hacking tools from the U.S. National Security Agency, which they used in 2016 to attack U.S. allies and Europe. and private companies in Asia, the incident is the latest evidence that the United States has lost control of a key part of its cybersecurity arsenal. Ironically, based on the timing of the attack and clues in the computer code, Symantec researchers believe that the Chinese did not steal the code, but rather from an NSA attack on Chinese computers. Captured – like a gunslinger grabs an enemy’s rifle and starts fighting back.

ON Semiconductor Advanced Automotive Lighting Solutions

In today’s mid-to-high-end cars, the modern lighting concept is more and more vividly interpreted. Both exterior and interior lighting are stylish and personal, with mood settings used in different parts of the car to control the color and brightness of light in “personal spaces” such as the driver’s footwell or the backlighting of the console. This type of automotive lighting uses a new type of light source, which not only enriches the consumer experience, but also meets the requirements of environmental protection and energy saving.

To realize advanced automotive lighting applications, there must be the support of corresponding semiconductor technologies. As a leading automotive lighting solution supplier, ON Semiconductor has been providing various general and dedicated high-efficiency device solutions for automotive lighting applications, in line with automotive applications. strict requirements to meet the rapidly developing market demand.

modern car lighting system

In recent years, luminousdiode(LEDs) are widely used in automotive lighting applications. Compared to incandescent lamps, LED-based lighting systems have a longer lifespan, lower power consumption, and greater design flexibility. These properties make it ideal for automotive interior lighting applications. In addition, as technology continues to advance, lower cost white LEDs with higher light output per watt are emerging, making LEDs more suitable for various lighting applications in the interior of the car.

LEDs are used in a wide variety of applications, such as in the headliner or in the lower trim of the doors, focusing light on specific areas inside and outside the car. LEDs can also be integrated near door handles, key holes, pedals, cup holders, or as turn signals on mirrors. The shape of the luminous indication can be very simple, or it can be very delicate to meet the precise lighting, provide convenience and beauty for people, as shown in Figure 1.

Figure 1: Various automotive lighting applications

Advanced Automotive Lighting Solutions from ON Semiconductor

ON Semiconductor has been providing standard products and custom devices for automotive lighting applications, including common light bulb driver solutions, as well as stepper drivers, LED drivers and high-intensity discharge lamp (HID, such as xenon) drivers.Dedicated in HID driveintegrated circuit(ASIC) market, headlamp leveling and rotary stepper drivers developed by ON Semiconductor have been widely used in the industry. In the automotive LED lighting market, ON Semiconductor provides a rich product portfolio for both interior and exterior applications. In the block diagram of the automotive lighting system shown in Figure 2, ON Semiconductor has various corresponding products. Several main solutions are described below.

Figure 2: Block Diagram of Automotive Lighting System

1. Headlamp stepper motor driver

Most of today’s cars are equipped with halogen lamps with high beam (HB) and low beam (LB) functions, which are the main function of headlamps. High beam halogen lamps have a typical power consumption of 55 W and a light output of about 1,000 lumens. HID technology has been around for more than ten years, with a power consumption of about 35 W and a light output of about 3,500 lumens, which has certain application advantages. Over time, HID lamps have incorporated high beam functionality into bi-xenon solutions. However, because the high brightness and glare of HID can affect the line of sight of approaching vehicles, some countries require automatic adjustment of the height of the low beam.

Another important aspect of automotive headlights is the Advanced Front Lighting System (AFS) beam rotation to optimize the visibility curve, while the Adaptive Driving Beam (ADB) function adjusts the beam according to real-time conditions. Stepper motors are the controller of choice for AFS and ADB.

ON Semiconductor’s AMIS-30623 single-chip bipolar stepper motor driver is suitable for headlamp leveling and rotation control. With an integrated position controller and local interconnect network (LIN) interface, the device enables the design of a dedicated mechatronic solution for remote connection to a LIN host, see Figure 3. It uses configurable parameters such as current, velocity, acceleration and deceleration to receive position commands over the bus and drive the motor coils to the desired position. The AMIS-30623 can also detect motor stalls.

The device embeds a dedicated finite state machine and a LIN instruction set tailored to the requirements of advanced headlamp systems, and integrates nosensorThe step damage detection function can not only improve reliability, but also reduce the number of components and board space, and reduce product cost.

Figure 3: Headlamp Leveling and Rotation Circuit Using AMIS-0623

2. LED headlamp system power ballast and dual LED driver

At present, most cars still use halogen headlamp solutions to provide high beam and low beam functions, but the future trend is to use xenon lamps and LED lamps. In particular, the application of LED lights, which can greatly reduce the power consumption of headlights, will increase rapidly, and 30% of cars will be equipped with multiple LED headlight functions within five years. LED lighting offers a sleeker option for “instant” lighting and allows brightness control from 0% to 100% power.

ON Semiconductor’s NCV78663 single-chip smart headlamp LED driver is a new device to be launched in 2011 that supports single-module control of high beam, low beam, daytime running lights, position lights, turn signals and fog lights . With integrated digital dimming, programmable serial peripheral interface (SPI) settings, and built-in diagnostics, the NCV78663 provides an integrated and comprehensive energy-efficient solution for headlamp control.

Figure 4: NCV78663 Single-Chip Smart Headlamp LED Driver

The NCV78663 uses a buck/boost topology to achieve LED current regulation, constant current sharing, high-efficiency integrated buck switching (high-side), and current up to 2 A using only a few external components; its extended diagnostic capabilities include: Open circuit or failing driver, short circuit, over current protection and single LED failure, etc. In addition, the device features thermal protection, system customization via SPI interface and/or OTP settings, multiple system configurations with one device, better EMC performance without additional filtering,BatteryLow EMC, LED string low EMC and other characteristics. Using the NCV78663 reduces the number of external components, and the total energy efficiency is better than 90%. An evaluation board for this device is available, see Figure 5.

Figure 5: NCV78663 Evaluation Board

3. Dedicated for full function of HID headlampsintegrated circuit

The advent of HID lamps improved the performance of headlamp systems. Compared to traditional halogen lamps, HIDs have improved color rendering, low power consumption, longer life and higher light output. To support advanced functions, HID headlamps require high-efficiency ballasts and complex control circuits.

ON Semiconductor HID lamp control system is an 8-bitmicrocontrolleror a hybrid analog/digital solution with a dedicated state machine, see Figure 6.The device integrates a DC/DC controller, as well as rich diagnostic functions (overvoltage, undervoltage, temperaturesensorlife counter), various communication interfaces (LIN, SPI), support 35 W (D1/D2/D3/D4) and 25 W (D5) lamps.

Figure 6: Dedicated to full function of HID headlampsintegrated circuit

4. Linear current stabilization and controller for automotive LED combined taillights

At present, automotive combination taillights (RCL) are increasingly using LED light body groups, which not only have beautiful appearance and high light efficiency, but also help the rear car to clearly see the driving state of the preceding car.

ON Semiconductor’s NCV7680 is a linear current regulator and controller that can power combination taillights from a single chip, providing better performance and higher energy efficiency in a smaller footprint than solutions on the market.The device includes 8 linear programmable constant current sources for current regulation and control of automotive solid-state combination tail lamps (RCL), supporting up to 75 mA per channel of light emissiondiode(LED) drive current.

The NCV7680 integrates numerous functions and supports two brightness levels, one for parking and the other for tail lighting. Optional pulse width modulation (PWM) control is also available if desired. The system designer only needs to use an external resistor to set the output current (overall set point). In addition, for designs requiring high currents, optional external ballast field effect transistors (FETs) can be used for power distribution according to the high currents required by the design. The delayed power limit reduces the drive current in overvoltage conditions. This is important for low current applications without external FETs.

Typical applications for this device include combination tail lights, daytime running lights (DRL), fog lights, center high mounted brake light (CHMSL) arrays, turn signals and other external modulation applications, liquid crystal Display (LCD) backlighting, lighting modules, and more. Compared with discrete solutions, the device can better match the LED output, open-drain output function of open LED string diagnosis, easy to find faults.

Figure 7: Application circuit with external FET transistor ballast

Summarize

ON Semiconductor has been leveraging its advanced automotive process technology to provide a variety of standard products and custom devices for automotive lighting applications. In addition to some of the solutions introduced above, there are also industry-leading products and solutions such as LED drivers using linear and switching power supplies (SMPS), LED current regulators, and central high-position brake light constant current regulators.

As with various automotive applications using advanced automotive process technologies, all of theseintegrated circuitThey all meet the requirements of automobile reliability and temperature and environmental protection requirements, and can meet people’s increasingly high requirements for interior lighting control, headlights, rear combination lights, fog lights, position lights, especially new light sources, etc. , allowing drivers to fully experience the comfort and fun brought by lighting.

What is SPC protocol decoding?How does it work with an oscilloscope

The SPC (Short PWM Code) protocol is an enhanced version based on the SENT (Single Edge Nibble Tranmission) protocol. It realizes data transmission through pulses between the falling edges of two adjacent cycles. Compared with analog output and PWM output, it has a good EMC characteristics, with high transmission speed, strong reliability and anti-interference ability.

SPC overview

The SPC (Short PWM Code) protocol is an enhanced version based on the SENT (Single Edge Nibble Tranmission) protocol. It realizes data transmission through pulses between the falling edges of two adjacent cycles. Compared with analog output and PWM output, it has a good EMC characteristics, with high transmission speed, strong reliability and anti-interference ability. This protocol is widely used for accurate rotational angle measurement and position detection, automotive applications including pedal, accelerator or gear lever position detection, suspension control or direct torque detection of electric power steering systems, etc.

The SPC protocol performs data transmission in the form of single-wire half-duplex transmission, and can control up to 4 sensors at the same time. Different from SENT, SPC adds a new trigger field, which can represent three modes: synchronization mode, ID selection and range selection. The value of each field of SPC represents a four-bit value according to the time between two falling edges. The result obtained by dividing the falling edge time by a fixed value minus 12 is the value represented, and this fixed value becomes the unit. time (UT).

SPC frame format introduction


Figure 1 SPC frame format

・Trigger field (master Trigger Pulse): sent by the host, the length is different according to the mode.
・Sync frame: sent by the slave, indicating that the slave starts to collect data.
・Status field (status Nibble): Indicates the current status of the slave. When the mode of the trigger field is ID selection or range selection, it also indicates the ID or current range value of the slave.
・Data Nibble: Indicates the data collected by the slave. According to the settings of the slave, the number of data fields can vary from 3 to 6. Its data can include Hall value and temperature value.
・Check field (CRC Nibble): Provide a check value to check whether the frame is correct.

introduction

Currently, high-precision A/D conversion and real-time processing are increasingly required in many fields. At the same time, the market demands to support more complex display and communication interfaces are also increasing, such as environmental monitoring, electricity meters, medical equipment, portable data acquisition, and industrial sensors and industrial controls. The traditional design method is to use MCU or DSP to control the A/D conversion of data acquisition through software, which will frequently interrupt the operation of the system, thereby weakening the data computing capability of the system and limiting the speed of data acquisition. In this paper, the scheme of DSP+FPGA is used, and the A/D conversion and data storage are controlled by hardware, so as to maximize the signal acquisition and processing capability of the system.

system structure

The whole acquisition card includes signal conditioning, data acquisition, data processing and bus interface design. The system structure is shown in Figure 1.

 

Figure 1 System structure block diagram

In this paper, a signal conditioning circuit with functions of signal attenuation, gain amplification and filtering is designed. The AD7676 A/D converter with 16-bit precision and a maximum sampling rate of 500KSPS is used. The digital system design uses the extremely flexible and programmable characteristics of FPGA. Altera’s FPGA chip EP2C8Q208 completes precision correction and logic timing control; DSP uses TI’s TMS320VC5416, so that the A/D-converted data is processed, marked, packaged and pre-processed before being transmitted to the host computer. The data acquisition card can perform 8-channel data acquisition at the same time, and the channels can be set for attenuation multiple, sampling speed and amplification gain. It also provides analog output channels for waveform generation and analog drive functions. Automatic calibration can be performed to ensure the accuracy of data collection. The PCI bus interface circuit adopts the PCI bus interface chip PCI9030 of PLX Technology Company to complete data acquisition and transmission of status and control signals.

System hardware circuit design

Design of Data Acquisition Module

The 8-channel analog input signals sent from the sensor are selected to enter the analog channel through the multi-channel analog switch ADG507. If multiple channels are collected at the same time, the time division multiplexing method is adopted, and the FPGA controls the on-off of each channel in turn. The mode selection switch ADG509 is a four-to-one analog switch, which can select the analog signal under test, the standard reference voltage value or the signal converted by the DAC for channel calibration and enter the post-stage filter attenuation network circuit. The signal sent to the ADC is first low-pass filtered to filter out high-frequency noise. The filter circuit is designed as a second-order resistance-capacitance low-pass filter, which filters signals with a frequency higher than 50KHz. The attenuation circuit is designed as active attenuation. The differential amplifier LTC1992 from Linear Company is used to complete the polarity conversion of the input signal, and realize the conversion of single-ended signal to differential signal. Adjustment of signals with different voltage input ranges to meet the input voltage range of the AD7676. The signal gain programmable amplifier LTC6911 can be programmed to set the gain multiple of 1 V/V~100 V/V in steps of 1, 2, and 5. During the data acquisition process, the gain multiple of the gain amplifier is automatically adjusted by the comparison circuit inside the FPGA. The ability to distinguish weak signals is greatly improved. AD7676 is a differential signal input. The MAX6325 reference source provides a reference voltage of 2.5V. The sampling clock is obtained by the crystal oscillator providing a 10MHz clock signal through the internal frequency division circuit of the FPGA. The maximum sampling rate of a single channel is 500KSPS.

FPGA circuit design

FPGA chip is also a special ASIC chip, which belongs to programmable logic device. It is developed on the basis of logic devices such as PAL and GAL. Compared with the previous PAL, GAL, etc., the FPGA scale is relatively large, and is suitable for logic circuit applications such as timing and combination. This text selects the FPGA chip EP2C8Q208 of Altera Company to complete the sequence and address decoding circuit design of the data acquisition card. Since EP2C8Q208 has 36 M4K RAMs, a 16-bit width and 4KB depth FIFO is designed inside the FPGA, and the FIFO is used to improve the data acquisition card’s ability to collect and store multi-channel signals. The FIFO has half-full, full, and empty flag bits. When the DSP detects the half-full flag bit, the FIFO reads and writes at the same time; when it is full, it reads only and does not write; when it is empty, it only writes and does not read. The A/D sampling control signal is controlled by the DSP through the FPGA; the DSP further processes the collected data to improve the accuracy, and also has the functions of a traditional CPU or MCU to handle timing, triggering, and DMA interrupt requests accordingly.

DSP circuit design

The DSP adopts TMS320VC5416, which is a 16-bit fixed-point DSP with high operational flexibility and high running speed. It adopts an improved Harvard structure (1 set of program memory bus, 3 sets of data memory bus, 4 sets of address bus), with dedicated Hardware logic CPU, on-chip 128KB memory, on-chip peripherals, and a highly efficient instruction set.

The role of DSP in the system is mainly to organize, mark, pack and pre-process the data after A/D conversion before it is transmitted to the host computer. All the control signals of the data acquisition system are generated by the DSP controlled FPGA logic circuit. DSP plug-in Flash stores DSP programs and other configuration data. When powered on, DSP uses parallel mode to transfer into DSP for internal execution.

Calibration Circuit Design

The calibration circuit is an important part of this design. The high-precision performance of the data acquisition card depends not only on the high-resolution ADC, but also on the excellent self-calibration and anti-noise capabilities of the data acquisition card to a greater extent.

During calibration, the DSP sends out the standard value. After D/A and A/D conversion, the collected data value is compared with the original standard value, and its deviation coefficient is used to form a denoising equation to realize the self-calibration of the data acquisition card.

PCI bus interface circuit design

The PCI bus specification is very complex, and the realization of its interface is difficult. The data acquisition card uses PCI9030 as the user interface, which provides a simple method for the development of the PCI bus interface. It only needs to design a simple local bus interface control circuit to realize the high-speed data transmission of the PCI bus. The use of Altera’s Quartus II enables the hardware to realize software design, updates the traditional circuit design and debugging methods, and greatly shortens the development cycle. In particular, its design simulation and timing analysis make the design more reliable and ensure the correctness of the system.

System software design

driver design

In the Windows98/ 2000/ XP environment, the application program in Windows user mode cannot directly operate the hardware device. To achieve access to the hardware resources (such as memory, interrupt, etc.) device driver. At present, the most used development tool is WinDriver, the driver development component of GUNGO. The use of WinDriver to develop drivers does not need to be familiar with the kernel knowledge of the operating system. All functions in the entire driver program work in user mode, and achieve the purpose of driving hardware by interacting with WinDriver’s .VXD and .SYS files. Because the WinDriver development environment provides modules such as memory range, registers and interrupt processing for PLX’s Chips, this paper adopts the WinDriver5.3 development tool of GUNGO, which supports the PCI interface chips of PLX, and users do not need to have DDK and core state. Program development experience, can be combined with PLX company’s PLXmon tool when debugging.

Operation interface design

The interface is designed using LabVIEW software from National Instruments. LabVIEW is a graphical programming language. The operation interface simulates the control panel of the actual instrument, enabling users to complete functions such as channel selection, mode selection, gain setting, sampling rate setting, etc. The operation is simple and convenient.

System Indicator Analysis

ADC Error Analysis

Commonly used ADCs mainly have quantization errors, gain errors and offset errors. The quantization error exists in any ADC and can only be reduced by increasing the ADC resolution. In order to reduce the quantization error to ±1LSB/2, the usual method is to shift the transform characteristic by 1LSB/2. Offset error is the difference between the actual code and the ideal code when using a zero-volt differential input to the ADC.Gain error is the transition from negative full scale to

The difference between the actual slope and the ideal slope for a positive full-scale input. Offset and gain errors are often the dominant error sources in ADCs. For offset calibration, this article takes a 0V or very small signal and reads the output code. If the result is positive, the converter has a positive offset error and the offset value is subtracted from the result; if the result is negative, the converter has a negative offset error and the offset value can be added to the result. Gain calibration is accomplished by applying a full-scale or near-full-scale signal to the ADC and measuring the output code. Offset calibration is performed before gain calibration.

Analog Switch Error Analysis

Multiplexers can be broadly classified into two types, analog Electronic switches and mechanical contact switches. The analog switch has the advantages of fast conversion speed, long service life, small size, low cost, high integration and no jitter; but there are also some disadvantages, such as large on-resistance, inter-channel interference, and common ground between channels.

The data acquisition card designed in this paper uses ADI’s ADG507 and ADG509, the on-resistance Ron100~300Ω, the input signal should be divided by Ron, and the output voltage to the load resistance should drop a little. For this reason, this design uses OPA2277 as a voltage level follower and connects it to the load circuit behind to pull up the load impedance of the multi-channel analog switch and weaken the influence of the series internal resistance.

Precision Design

The data acquisition card uses the programmable gain amplifier LTC6911, and the maximum adjustable gain is 100 V/V, which greatly improves the ability of the acquisition card to distinguish weak signals. At the same time, the resistance attenuation network of the signal conditioning part can complete the 1/2 and 1/4 voltage division of the signal, which expands the dynamic range of the data acquisition card. Signal and interference noise are mixed together in the time domain, but have different characteristics in the frequency domain. Therefore, pre-design filters to suppress the noise signal to avoid high noise levels. Receiving such a signal with a gain amplifier will cause the amplifier to saturate. make the instrument not work properly.

The voltage reference source is an important part of the A/D or D/A conversion circuit, and the system output accuracy largely depends on the accuracy of the voltage reference source. Here mainly consider the output accuracy, stability and temperature drift coefficient. The MAX6325 is a low-noise, high-precision buried Zener voltage reference chip with an initial output voltage accuracy of 0.02% and a temperature coefficient of 0.5ppm/°C.

Epilogue

The data acquisition card adopts 16-bit precision ADC. The analog signal channel design considers weak signal detection, noise suppression, high-frequency filtering, differential amplifier circuit and programmable gain amplifier circuit. The digital circuit part is designed with EP2C8Q208 as the core, and the timing sequence of FPGA is strictly used. , fast speed, good programmability and other characteristics, introduce various control and status signals that may be required into FPGA, and use the large capacity and field programmable characteristics of FPGA to make field modifications according to different requirements, which increases the system design. success rate and flexibility. At the same time, the preprocessing of the data by DSP greatly improves the accuracy of the data. Filtering, grounding and reasonable signal routing are carefully considered during PCB wiring, which improves the reliability of the data acquisition card.

Medical records will be a key factor in Apple’s health strategy

As Apple enters the healthcare market, establishing itself as a platform for consumers’ personal health records will be central to the tech giant’s strategy for apps, services and wearables, according to a new report from research firm CB Insights. According to the report, Apple aims to exploit the inadequacy of the third-party developer ecosystem for medical data by building the first open marketplace platform modeled on the attractive third-party developer ecosystem it has created in the App Store. . .

Apple’s current market players include health IT and Electronic medical record (EMR) companies as well as medical device makers that are making consumer-facing goods, the report said. By empowering patients to make decisions and providing access to data to anyone they choose, Apple’s strategy has the potential to become a new paradigm for healthcare, the research firm suggested.

The company acquired personal health records startup Gliimpse in 2016. Step trackers and calendars give consumers reason to use the app on a regular basis, which also tracks health metrics such as physical activity, mindfulness, nutrition and sleep. Apple said in 2018 that it would integrate EMR data into iPhone health records and would open up APIs to third parties through a software development tool called HealthKit.

  

The report notes that Apple is part of an organization that pushes the “Fast Healthcare Interoperability Resource (FHIR)” technology to improve the standard for data exchange between hospitals, doctors and other interested parties. According to CB Insights, more than 120 healthcare organizations are part of the beta version of Apple Health Records, including Adventist Health System, Mount Sinai, Cleveland Clinic, Intermountain Healthcare and LabCorp.

Apple’s strength lies in its strong brand. The report states: “The notoriously poor brand and customer experience of the various existing healthcare companies has been a major focus for Apple. As healthcare evolves towards a more proactive model, this requires patient coverage, having A strong brand is the main factor.” states.

Apple could also reshape the medical research industry, CB Insights said. In 2015, the company launched ResearchKit, which allows medical researchers to conduct research using the iPhone. The toolkit simplifies the process of registering studies and can identify qualified candidates through their health records. It also enables remote monitoring of patients. Building on the success of ResearchKit, Apple launched CareKit in 2016, allowing doctors and hospitals to monitor patients.

The company has taken a major step in the medical device space, receiving approval from the FDA in September for an Apple Watch Series 4 app that provides a single-lead electrocardiogram for heart monitoring. CB Insights said Apple has built other health capabilities with key partners in areas such as mindfulness and physical activity, treatment of stroke patients, psychiatric care support, ADHD, migraine prevention and overeating.
