Low-key Euler, Huawei’s new “Wang Zhuang”!

The light of domestic operating systems – the times need Euler

On September 25, Huawei’s official Weibo announced the new openEuler (Euler). What Euler means may not be clear to many people.

The current operating systems are divided into several categories: mobile phones (iOS, Android, Hongmeng), PCs (Windows, MacOS, Linux), servers including embedded (Windows Server, Linux Server). Among them, iOS and Android of mobile phones (the two combined are almost 98%), Windows and MacOS of PCs (about 90% of the two), Windows, Redhat Linux, etc. of the server are all American.

In the current situation, are the people still not alert? Combined with the recent rumors of hospital XX equipment data leakage and censorship of a taxi software, we can see the importance of basic software to our national security. The operating system is the foundation of the basic software.

The reason why Hongmeng caught fire in June was that everyone saw that it broke the monopoly of the US mobile phone operating system on the C side. Recently, Huawei officially announced that the number of terminals based on Hongmeng has exceeded 120 million, which fully proves the power of the Hongmeng system. On the mobile phone side, China has a solid foundation with Hongmeng.

What’s more powerful is that both Hongmeng and Euler are developed and open sourced by Huawei. Both the C-side and the B-side stand, and the cooperation between the two will obviously be better than the general cross-manufacturer, which will be in the world. is leading.

The new journey of casting soul of “Euler + Hongmeng”

The application scenarios of Hongmeng OS are intelligent terminals, IoT terminals and industrial terminals; Euler OS is oriented towards servers, oriented to edge computing, oriented to cloud and oriented to embedded devices. With the two major systems of Hongmeng + Euler, Huawei has gradually started a new journey in the field of operating systems.

It is understood that Euler and Hongmeng have realized the sharing of core technology. In the future, they plan to build a distributed soft bus capability in Euler, so that devices equipped with Euler’s operating system can automatically identify and connect to Hongmeng terminals. In the future, sharing will be further achieved in terms of security OS, Device driver framework, and new programming languages. Through capability sharing and ecological interoperability, “ORA + Hongmeng” can better serve all digital scenarios.

At the same time, in order to accelerate the application of Euler’s scenarios, the community has made 100% compatibility or coverage of mainstream computing power, mainstream boards, and mainstream application scenarios. Mainstream OSVs such as Hongqi, Thundersoft, and Institute of Software, Chinese Academy of Sciences all release commercial distributions based on the Euler open source operating system. Leading companies such as Baidu, Telecom Tianyi Cloud, China Mobile Research Institute, and UnionPay are already loyal customers of Euler.

Through the alliance with all industry partners, Euler open source operating system has built a mature ecosystem with diverse computing power, which is suitable for application scenarios such as database, big data, cloud computing, artificial intelligence, etc., and has become the preferred technical route for enterprises.

“Through Hongmeng and Euler, we want to create an operating system that covers all scenarios, all open source, let the industry participate, make it better, and be suitable for more products,” Xu Zhijun pointed out, “In our new After positioning the role of the Euler operating system, if we can get active support from the industry, and through joint efforts, we can achieve all the current planning goals, China’s “Soul Casting Project” can achieve the goal, and our country has a “soul” .It can really solve the “less soul” problem of China’s information infrastructure, solve the most critical problems of information security, and solve the problem of operating systems in all walks of life.”

Will Huawei become a software company in the future?

At present, Huawei’s business related to chips, especially those related to advanced process chips, will have huge risks. Huawei, living in the shadow of America’s Entity List, is clearly in transition at this stage.

For example, in cloud computing, HUAWEI CLOUD is already No. 2 in the public cloud market, with a year-on-year growth of 168% in 2020. Even with an 18% increase, within 10 years, Huawei’s cloud computing will become a business with revenue exceeding 100 billion yuan.

Cloud computing requires a large number of servers. Huawei’s self-developed, ARM-based Kunpeng server chips cannot be OEM and can only rely on Intel. However, Intel’s supply license has been revoked in early 2021.

In the shrinking web of chips, Huawei seems to have only one way out: software.

The software here is not to develop a set of software to sell in our conventional understanding, but to provide a digital solution, which also includes complex software and hardware.

IBM was a PC company before the transformation. Gerstner carried out reforms after the transformation. Today’s IBM mainly provides comprehensive cloud computing solutions. Although Amazon is a home appliance company, its AWS cloud computing profit growth rate today. Already approaching the profit of the main business of e-commerce, including giants such as Microsoft and Google, they are also competing fiercely in the field of cloud computing.

Although Apple still mainly sells hardware products such as mobile phones, the proportion of soft revenue such as music video content and membership services has also increased year by year. Sony’s games, film and television and other content products have always been an important source of Sony’s profits. Qualcomm The profit margin brought by patent revenue is no worse than that of Qualcomm chips.

Therefore, looking at the global technology giants, software product layout and market promotion have become trends. In the future, in the digital society, in order to compete for the right to speak in numbers, giants have made great efforts to make huge investments. In the future, between giants , there must be a wonderful battle in the core digital competition field.

As one of the global communication giants, Huawei, the former overlord of mobile phones, naturally cannot be absent. The obstruction of Huawei’s mobile phones has in turn accelerated Huawei’s advancement and layout in the software field.

The transformation of the Hongmeng system, the familyization of Petal Software, and the launch of the mobile application engine all demonstrate Huawei’s determination in the software field. Therefore, there is reason to believe that even if Huawei does not make mobile phones in the future, Huawei is still a world-leading digital software company.

Trump administration: Stop Intel’s supply to Huawei, Huawei’s PC business is in danger

According to the latest news, Huawei’s PC business is also in danger. In extreme cases, it may follow the footsteps of the mobile phone business and face a desperate situation!

According to Reuters news on January 18, sources told Reuters a day earlier that the Trump administration had notified several chip makers, including Intel, that supply Huawei, it would revoke some licenses to sell products to Huawei, and , plans to reject applications from dozens of other companies to supply Huawei.

Screenshot from Reuters website

Previously, the Trump administration’s sanctions against Huawei have been considered to have reached the level of “extreme sanctions” many times, but the supply of PC chips has not been explicitly restricted, and the industry also believes that this field does not involve 5G, nor can it reach “Threats to national security”, so few analysts believe that this aspect will be limited. But… the Trump administration seems to be determined to do more before the official change, and cut off the supply of PC chips to Huawei.

Given that January 20 is the day of the inauguration ceremony of the newly elected US President Joe Biden, and there are only two or three days left, many media speculate that this may be the last move against Huawei during the Trump administration’s term. . But… according to Trump’s crazy character, it’s actually hard to say. After all, last Friday (15th), when the Trump administration sanctioned companies such as Xiaomi and COMAC, the media also guessed a round of “final moves”, but the results are still miscalculated.

On January 14, US local time, the outgoing US President Trump, his team once again attacked China’s leading large enterprises. Based on “misconduct in the South China Sea”, “military end users” and other reasons, the U.S. Department of Defense and the Department of Commerce imposed sanctions on relevant Chinese officials and companies, adding Xiaomi, COMAC, China Micro semiconductor, High At the same time, nine Chinese companies including Cloud Semiconductor have included CNOOC on the “entity list” and Beijing Skyrizon on the “military end user” (MEU) list.

Now it turns out that Trump’s madness is always unexpected…

The Trump administration says Huawei, the world’s largest maker of communications equipment, threatens U.S. national security and foreign policy interests.

According to Reuters, the relevant email content shows that the American Semiconductor Association said on January 15 that the Commerce Department had issued a “rejection of multiple applications for export licenses to Huawei and the intention to cancel a previously issued export license.” According to anonymous sources, more than one export license was cancelled. The email said the action involved a “wide range” of products in the semiconductor industry and asked if companies had been notified.

Before the operation, some 150 export licenses worth about $120 billion were awaiting approval, the sources said, which had not been approved due to the inability of various U.S. government agencies to reach an agreement.

Chemical Heat Treatment of Steel in CNC Machine Tool Plant

Chemical heat treatment is to place a metal or alloy workpiece in an active medium at a certain temperature for heat preservation, so that one or several elements penetrate into its surface to change its chemical composition, structure and properties. Compared with surface quenching, chemical treatment not only changes the structure of the surface layer, but also changes the chemical composition of the surface layer. After chemical heat treatment in CNC machine tool factory, combined with conventional heat treatment, the surface and core of the same workpiece can obtain different microstructure properties.
The CNC machine tool factory can be divided into carburizing, nitriding, carbonitriding, boronizing and dissolving chromium, etc. according to the different elements infiltrated.
1) Port carbon of CNC machine tool factory steel
Carburizing is a chemical heat treatment process in which steel workpieces are heated and maintained in a carburizing medium to infiltrate carbon atoms into the surface layer. The main purpose of the carbon is to improve the surface strength, wear resistance and fatigue strength of the workpiece, while maintaining the good toughness of the core.
Carburizing steels are generally low-carbon non-alloy steels and low-carbon alloy steels, and the carbon content is oi%-o.2s%. The traditional carburizing methods include gas, liquid, and solid. Gas carburizing is commonly used in CNC machine tool factories. In order to improve the efficiency and quality of carburizing, new technologies such as vacuum carburizing and vacuum ion carburizing are gradually being promoted and applied.
2) Chlorination of steel in CNC machine tool factory
Nitriding is a chemical treatment process in which nitrogen is infiltrated into the surface of the workpiece to obtain a high nitrogen hardened layer. The purpose of nitriding is to improve the surface hardness, fatigue strength, adhesion resistance and wear resistance of steel.
The steel for nitriding is usually steel with alloying elements such as Al, Cr, Mo, Ti, V, etc., because these elements easily form various nitrides with fine particles, uniform distribution, high hardness and stability with ammonia. After nitriding, the workpiece will obtain high hardness, and no quenching treatment is required. In order to ensure the mechanical properties of the core, quenching and tempering treatment should be carried out before nitriding.
Compared with carburizing, the workpiece after nitriding has high hardness, wear resistance and hot hardness without quenching. However, the chlorine time in the roadway is long, the cost is high, and the nitriding layer is thin and brittle, which cannot withstand the impact. It is mainly used for precision parts with high surface hardness, wear resistance, corrosion resistance and high temperature resistance, such as precision machine tool spindles, screw rods, etc.
3) Carbonitriding (cyanidation) of steel in CNC machine tool factory
Carbonitriding is the process of carburizing and ammonia to the surface of steel at the same time, which is customarily called cyanidation. Cyanidation in CNC machine tool factory is to put the workpiece in an active medium containing cyanide or cyanide, and after heating and holding for a certain period of time, carbon and nitrogen will diffuse into the surface layer of the workpiece. Because cyanide is highly toxic, gas carbonitriding has been gradually used instead of cyanide. At present, there are many applications of medium temperature gas carbonitriding and low temperature gas carbonitriding. Medium temperature gas carbonitriding is mainly carburizing, and its purpose is to improve the hardness, wear resistance and fatigue strength of steel; low temperature gas carbonitriding Co-infiltration is mainly based on fluorine infiltration, and its purpose is to improve the wear resistance and adhesion resistance of steel.

Application of various sensor technologies in vehicle air purification system

With the increasing market demand for family cars, many cars have entered the market directly after the production line. There is no release period for the harmful gases and odors of various accessories and materials. The plastic parts, carpets, and roof felts installed in the car If you do not comply with strict environmental protection requirements, it will directly cause air pollution in the car.

With the increasing market demand for family cars, many cars have entered the market directly after the production line. There is no release period for the harmful gases and odors of various accessories and materials. The plastic parts, carpets, and roof felts installed in the car If you do not comply with strict environmental protection requirements, it will directly cause air pollution in the car.

In-car air purification market has broad prospects

With the intensification of air pollution and smog in various places, bacteria and viruses are rampant, and air purification has become a hot spot. As a space for people’s daily contact, air purification in the car has also become the focus of attention. In response to this consumer demand, many domestic auto companies are currently taking air purification in the car as a prominent selling point of their products. Relevant experts said that the air purification technology market has broad prospects, and the size of the air purification market in vehicles alone is expected to reach one trillion yuan.

Air pollution in cars is seriously harmful

source of pollutants

1. During the production of vehicles, a large number of plastic products and adhesives are used for interior parts. These are the main culprits of environmental pollution in the car. The solvent used in the adhesive is the main source of pollution in the car.

2. After the engine runs for a long time, not only the heat generated by it will increase the volatilization of pollutants in the car, but also the amine, nicotine and other substances produced by itself will also cause harm to the body of the occupants.

3. Putting some inferior plush toys, cushions and other decorations in the car will increase the release source of “formaldehyde” in the car. Others like to spray perfume in the car. Many perfumes are chemical compounds, which also contain harmful substances, which will only increase the pollution.

4. Automobile exhaust gas. There are about 150 to 200 kinds of exhaust gases after chemical analysis, among which carbon monoxide, hydrocarbons, nitrogen oxides, carbon and other gases and particulate matter are more harmful to human body.


Air pollution in the car not only causes the air in the car to smell unpleasant, but more seriously, some harmful substances may have adverse effects on physical health; in addition, driving in a polluted environment for a long time will cause the driver to dizziness, drowsiness and other adverse effects Reactions, which in turn lead to inability to concentrate, may lead to traffic accidents.

A variety of sensors to achieve air purification system solutions

In an air purification system, a variety of different sensor technologies are required to monitor, purify, and maintain a comfortable, clean, and safe in-car environment. The temperature and humidity sensor HTW-211, PM2.5 particulate matter sensor TF-LP01, PM2.5 PM1.0 sensor GPSM series, VOC air quality sensor TGS2602, etc. provided by Gongcai.com are used in the whole air purification system. Accurate and effective data monitoring of temperature, humidity, particulate matter concentration, volatile organic compound concentration, etc.

Intelligent purification

When the monitored data exceeds the standard, the system will first command the air conditioning system to use the external circulation to inhale fresh air, and filter pollen, odor and some allergens through the filter element. There is a purifier in the car, which can be linked with the purifier to turn on the purification function.

Intelligent temperature control and humidity control

Install the temperature and humidity sensor HTW-211 near the cockpit in the car, and adjust the dehumidification mode of the air conditioner by detecting the humidity in the cockpit to avoid excessive humidity in the car or drying due to excessive dehumidification. If there is a humidifier in the car, also It can be linked with the humidifier to turn on the humidification function. The HTW-211 temperature and humidity sensor produced by South Korea’s Samyoung has cooperated with Ford Motor. So far, the field defect rate has reached 0ppm. Ford Motor has recognized the quality and durability of South Korea’s Samying HumiChip temperature and humidity sensor, ensuring AEC-Q100 1 level of vehicle reliability. Passed the AEC-Q100 vehicle regulation certification.

There are generally 1-2 temperature and humidity sensors located in the ventilation ducts in the car compartment, which measure the temperature in the car, transmit the signal to the Electronic control unit of the automatic air conditioner, and adjust the car temperature suitable for the human body.

Google’s Android 11 conference schedule officially released

The 2019 Android Developer Summit will officially kick off later this month, and Google released the official conference agenda yesterday. It is worth noting that the official first official reference to “Android 11” is in this schedule.

It is reported that there will be a session called “Preparing for Android 11 Storage” at the two-day Mountain View conference. This is also the first time that the official has recognized the next Android system version after switching to a new naming scheme in late August and launching Android 10 last month.

The new system name and codename are not surprising, but it means that Google officials will directly use “Android 11” instead of using the codename when discussing the operating system with developers in public in the future. Some foreign media have found references to Android R from Googlers from AOSP, and the company has previously confirmed that the internal codename of the new system will continue to be used during development.

Google appears to be trying to cover up the “official certification” regarding Android 11, with full session details only appearing on the Android client and not on the web version. The talk itself was about a whole new way of storage.

Digital Transformation Framework: Launch, Build, and Scale

In order to ride the wind and waves in the digital wave and forge ahead, enterprises need a “hard work” that can quickly transform. A recent McKinsey survey found that 65% of businesses are increasing their digital and technology investments to keep pace with changing market conditions. In fact, the process of integrating these technological measures is digital transformation. To ensure success, companies need to develop their own digital strategy framework. This article will introduce the three stages of digital transformation: launch, build and scale, and hope to inspire you.

By Roald Kruit, Co-Founder of Mendix

In order to ride the wind and waves in the digital wave and forge ahead, enterprises need a “hard work” that can quickly transform. A recent McKinsey survey found that 65% of businesses are increasing their digital and technology investments to keep pace with changing market conditions. In fact, the process of integrating these technological measures is digital transformation. To ensure success, companies need to develop their own digital strategy framework. This article will introduce the three stages of digital transformation: launch, build and scale, and hope to inspire you.

What is the Digital Transformation Framework?

If digital transformation is the process of integrating digital technologies that help businesses succeed, then the digital transformation framework is the roadmap to success. eWeek defines a digital transformation framework as “a step-by-step plan for the successful implementation of a digital transformation strategy”. The framework is divided into three phases: launch, build, and extend.

Phase 1: Launch

During the startup phase, companies can start small and gain broader support for digital execution initiatives by proving the value of new approaches. At this stage, it is necessary to ensure that the first initiatives can be successfully implemented and have a PR effect internally. The first project needs to have a “wow” factor that generates business value, so that it can be a “catalyst” for other projects and generate support and attention across the company. As Plautus puts it: “One eyewitness is better than ten rumors. The whole world believes in seeing is believing.” Therefore, it is important to choose the right first projects. In addition, companies need to meet some necessary prerequisites, including:

• infrastructure
• Business case
• The right partner and team

Stage 2: Build

When entering the build phase, companies should begin to focus on building teams and developing strategies to accelerate the implementation of digital transformation initiatives. The main goals of this phase are to form a dedicated team, identify training needs and develop a procurement strategy. Another important goal was to distill the successful practices of the first projects and use them as reference templates for future projects.

As the number of applications increases, other topics will also become important, such as: rapid continuous delivery through DevOps, governance and architecture focused on ensuring application maintainability and compliance, and more.

Phase 3: Expansion

The main work of the expansion phase is to transform the enterprise into a true digital enterprise through greater automation to achieve the efficiency required to deliver and manage hundreds of applications. These jobs include:

• Support a large product portfolio by automating deployment and maintenance
• Join the quality inspection process to actively monitor the maintainability of the project
• Improve reusability by creating a dedicated app store

With these capabilities, businesses can build distributed innovation capabilities within the organization, enabling multiple teams to develop collaboratively, ultimately maximizing value and productivity.

Digital Transformation Examples

The Dutch semiconductor equipment manufacturing company ASML makes good use of the concept of expansion. The company, which has revenue of £11.9bn, aims to double that revenue by 2025. ASML realized during the time-consuming process of building a custom app that it had to accelerate development if it wanted to achieve its revenue goals. To scale quickly, they not only needed to recruit staff, but also had to find a way to optimize their processes to increase the productivity of their teams.

ASML achieves large-scale development of applications by using Siemens’ low-code App Factory framework, thereby gaining business opportunities. Not only is the framework a successful digital transformation tool, but it also provides a detailed reference of the steps ASML needs to take. Roy Coenders, ASML Shared Services Manager, said: “In working with Siemens Low Code, we have learned to prioritize tasks at the right level.”

In the end, the ASML team quickly developed five applications, one of which took only two and a half weeks to develop.

The challenges of digital transformation

When developing a digital transformation framework, if you rush to scale and immediately invest in scaling, companies are likely to fail for two reasons:

• “One bite can’t make a big fat man”: Organizations simply cannot manage such a large-scale change at one time, and making drastic innovations when the management ability cannot afford it will make the enterprise stagnate.

• Unproven innovations are highly disruptive: Businesses cannot innovate at scale based on assumptions, but rather on best practices.

It is for these reasons that we created our digital transformation roadmap. Based on Siemens Low Code’s experience working with hundreds of customers, this digital transformation framework will help companies do the right things at the right time, guiding them through the three key transformation stages of launching, building and scaling.

The key to digital transformation is timing: neither do everything at once, nor spend too much time on something. For example, if an enterprise development team forgets to address governance issues during the build phase, it can create chaos later, incurring high restructuring costs and hindering further development. Siemens Low Code has guided hundreds of customers on their digital transformation journey through low-code application development, and experience-based best practices can help companies focus on the right things at the right time.

Flexible replacement, no fear of missing cores, modular design in ARM industrial control boards!

In the face of diversified demands and tight supply of raw materials, modular design can be freely matched and flexibly replaced, especially for small-scale mass-produced products, which have obvious delivery time and cost advantages.

2022 is a year full of uncertainty. Issues such as rising material prices and extended delivery times will continue to affect product delivery. How to minimize the impact from the design process? The following will take HDG2L-IOT as an example to introduce the modular design in the ARM industrial control board.

HDG2L-IOT is a cost-effective industrial control board based on Renesas RZ/G2L dual-core A55 processor. Its WIFI, Ethernet, USB, audio, 4G/5G and other parts are modularly designed. The concept is free matching and flexible replacement.

WiFi module

Wifi communication scenarios are rich and the needs are wide. The WIFI module compatible with USB interface and SDIO interface is designed here, which can cover most of the common WIFI modules on the market. For Bluetooth & WIFI integrated module, 2.4G & 5G Wifi module can be easily adapted.

HDG2L-IOT adopts the compatible design of high-speed USB communication interface such as RTL8723, RTL8821, RTL8188, and can choose single WIFI, WiFi+Bluetooth integrated module.

audio module

The main IC in the audio section is the WM8960, which is a low-power stereo codec that uses a class-D speaker driver to deliver 1 W per channel at an 8 W load. The module adopts a stamp hole design and integrates a complete microphone interface and stereo headphone driver. In addition, the audio chip with the same type of function also has TLV320, which can be modularized and replaced.

5G/4G interface module

At present, most of the pluggable 4G modules on the market have MiniPCIE interfaces, and most of the pluggable 5G modules have M.2 interfaces (with fewer MiniPCIE interfaces). In order to flexibly select 5G or 4G modules according to different application requirements, M.2 and MiniPCIE compatible interface boards are designed here.
