Once again, Huawei is far ahead. Can visual intelligence drive "hang" Tesla?

As we expected before, Huawei will never sit idly by in the face of the limelight.

At the HarmonyOS Ecological Spring Communication Meeting held on April 11th, Yu Chengdong took out the products that had not been listed for a long time before and "listed" them again.

However, don’t think this is "fried cold rice", because this time, Yu Chengdong has made a big move again.

This is Huawei’sVisual intelligent driving scheme.

When it comes to visual driving, you may think of Tesla for the first time. After all, Tesla was the first enterprise to do smart driving development along this technical route.

Different from the current mainstream high-order intelligent driving scheme, this technical route can not rely on lidar. Only millimeter-wave radar and high-definition camera are used to achieve high-level automatic driving assistance.

The advantage of this technical route is that the cost of bicycle parts can be greatly reduced. Although the BOM cost of lidar has been declining in recent years, in order to play the role of sensing hardware, it needs a high computing power chip, and the overall cost is still high.

Yu Chengdong has said many times before that the high-order ADS scheme with laser radar in HarmonyOS will lose money if the price is below 300,000 yuan.

However, the visual scheme also has its own disadvantages. First, in some extreme scenes (such as heavy rain and fog, strong backlight), recognition may be wrong. Second, if we want to deal with the complex road conditions like downtown areas, we also need a very large amount of code and computing power to support it without relying on the pure vision scheme of laser radar.

In this regard, Tesla’s solution is to borrow the end-to-end AI big model to replace the traditional perception, description, prediction, planning and other modules, and hand over the driving decision to AI neural network. However, the highest level of FSD has not been able to land, and the strength of castrated EAP is almost interesting, so the recognition of this technical route in the domestic market is relatively low.

So how did Huawei do it?

At this conference, the entry-level Pro model of Zhijie S7 showed Huawei’s thinking on visual solutions.

In hardware, Zhijie S7 Pro version uses 10 lateral and forward-backward sensing cameras, plus 3 millimeter-wave radars and 12 ultrasonic radars for fusion. The software part uses GOD general obstacle detection network and RCR road topology inference network. Functionally, it does not rely on high-precision maps to achieve high-speed navigation that can be opened all over the country.

In terms of hardware configuration, the perceived hardware gap between Pro version and MAX is only lidar. However, in terms of intelligence, the PRO version should be 48T, and the MAX version should be 200T.

According to the media measurement, the effect of this scheme is still quite OK. Whether it is high-speed NCA or APA parking, the strength can "hang" Tesla’s EAP. Even compared with Huawei’s advanced intelligent driving system, the performance of this pure vision scheme can also maintain the strength of the first echelon in various high-speed navigation systems.

Considering the lower hardware cost of this scheme, if it is further popularized, the lethality will still be very terrible.

Kung fu is angry

In the face of the "second half" of the smart electricity revolution, Huawei once again showed us the strength of its "arsenal".

Although the visual intelligent driving scheme released this time is ostensibly a "replacement" of Huawei’s high-end ADS. However, if the technology is further mature, it is not excluded that Huawei’s smart driving will gradually turn to a purely visual solution.

Memories kill! To the mobile phone designs we chased in those years: After reading it, I’m stuffed

  Many people say that this is an era of looking good. There are also many people who say that talent is the most important thing in this era.

  But what I want to say is that without good looks, who will pay attention to your inner self. This sentence also applies to the current mobile phone industry.

  In the mobile phone industry, a mobile phone without a good design may not attract your attention at all, and a good design is usually "borrowed" by manufacturers from each other.

  In this regard, the first thing we think of is Apple iPhone. If it hadn’t been for its emergence, we might still be in the era of "how can mobile phones look the same".

  Throughout the mobile phone industry, innovative designs have sprung up like mushrooms after a rain. Designs such as full-screen, ultra-narrow borders, retina, iris, and dual cameras have been "borrowed" by various manufacturers.

  However, there are also some mobile phone manufacturers who have always adhered to their own unique style. The classic designs of these manufacturers have not only become the object of imitation for other manufacturers, but also become the classic logo in the hearts of users. Today we will talk about the classic designs in those mobile phones.

  This is Nokia’s most classic design, and even Steve Jobs praised its beauty

  Although in the tide of smartphones, the former mobile phone overlord Nokia has long since lost its courage, as the earliest and most famous mobile phone brand in the mobile phone industry, Nokia has still brought us one classic product after another.

  Among them, there is such a machine, which is hailed as a classic of the generation, but the sales are not good; it has an excellent design, but it is dragged down by the system and does not go far. It is the Nokia N9.

  Released in 2011, the Nokia N9, with its droplet screen and colorful polycarbonate casing, was for a time the face of the electronics trend.

  The N9 is powered by the Meego operating system, which is also the first smartphone to use the Meego system, and the last phone from Nokia to use the system.

  At that time, Apple and other Android manufacturers patent war time. Nokia N9 turned out, really let everyone romance bright: the original large screen phone design can not follow the iPhone.

  Steve Jobs once said: "mobile phones (except iPhone) can do not like iPhone, Nokia N9 is a good example. Joe’s words are the biggest affirmation of the Nokia N9 design."

  Although the Nokia N9 has become a thing of the past, its innovative and cutting-edge design philosophy reflects Nokia’s capabilities and vision.

  The most classic design on HTC, even iPhone have borrowed

  Looking at any current smartphone, if you look closely, you can find Apple, HTC, or Samsung’s shadow in it, which is the big problem of smartphone homogeneity.

  The most popular design now is undoubtedly the three-stage all-metal back, which first appeared on the HTC One series.

  The two most famous phones are the HTC One M7 and the HTC One Max.

  Among them, the HTC One M7 launched in 2013 was the originator of the three-segment mobile phone. In that era, when many friends and businesspeople imitated the appearance of the iPhone mobile phone, HTC still adhered to itself and still adhered to the metal brushed design. The seamless connection between the round body, the frame and the back cover makes the whole machine feel very good.

  Another HTC One Max is the representative model of all-metal mobile phones, which was also released in 2013. The HTC One Max has an all-metal body, rear fingerprint recognition and a 5.9-inch 1080P display.

  This metal body antenna injection molding process is still the mainstream, and HTC has almost single-handedly created the industry standard. Although there are many latecomers, it has basically not jumped out of the HTC-style all-metal design framework.

  Sometimes sticking to your design is a good thing, but when the market feedback is not good, and you have been stubborn, then of course the consequences can be imagined. This sentence applies to HTC at the time.

  HTC’s stubbornness is mainly reflected in its criticized "multi-chin" design. For HTC, it has also been discussed internally. The stubborn HTC executives believe that this will affect the effect of the "HTC" brand, so not only did they cancel the physical buttons, but also let the HTC logo occupy a separate layer.

  HTC’s official explanation for this is that BoomSound is the main cause of double chin.

  Although the short-term sales of HTC A9 in 2015 temporarily relieved HTC’s urgent needs, it is clear that in that era of confluence, HTC’s market share is still declining.

  The high-end market cannot defeat Apple and Samsung, and the mid-to-low-end market cannot defeat Xiaomi, OPPO, Huawei and other manufacturers, so that the HTC brand’s presence in the mainland has become increasingly low.

  "Sony **** is good" is not a slogan, but a true craftsman spirit

  In the mobile phone industry, there was a manufacturer that had to go through dozens or even hundreds of "bankruptcies" every year. However, these public pressure did not make it go bankrupt. Instead, it made its fans hooked with one high-value product after another every year.

  For a long time, "****" has been synonymous with Sony, and "Sony **** is good" is also a slogan shouted by fans.

  This slogan shows that Sony’s contribution to the technology industry often exceeds that of many competitors, and it is also admired by many fans.

  In terms of the appearance design of mobile phones, Sony has also been adhering to itself. Basically, the general style of each generation is a square appearance style, with clear edges and corners, combined with the round middle frame design, plus the effect of matte glass, full of Japanese style, with a high degree of recognition.

  The first thing that makes me think of a more representative model is a mobile phone called LT18i launched by Sony in 2011. This mobile phone features a slim design, a metal brushed frame, and sharp edges around it, highlighting its domineering style.

  The perfect arc design on the surface of the fuselage has the arc of the "human body curve", and each arc is beautiful; a layer of piano paint on the surface makes the touch extremely comfortable. This design full of Japanese style is very recognizable.

  Among the fans of Sony mobile phones, female users make up a large part of the group, which has also made Japanese mobile phone manufacturers firmly target this group of people, and most of the products launched are biased towards female users.

  In the first half of this year, Sony’s Xperia XZ Premium National Edition was a product that made girls go crazy.

  This phone still uses the classic mirror design, continuing Sony’s usual square, tough style, although the appearance of the complained unchanged for ten thousand years, but Sony still insists on doing itself, the new product is still high value.

  It can be seen that Sony has been building one classic mobile phone after another on the basis of its unique design style over the years.

  In addition to the tireless pursuit of American models, Sony mobile phones are also constantly cultivating their internal skills to keep up with today’s young people’s pursuit of smartphone functions.

  BlackBerry’s full keyboard design has persisted

  There used to be a mobile phone that even US President Barack Obama had a soft spot for. For a while, its shape was not clear from the Nokia E series. Yes, this is the BlackBerry phone. In terms of feelings, it is definitely not inferior to Nokia. In terms of design, it is also definitely not inferior to Apple.

  In terms of design, the BlackBerry has always been an "outlier". Once the most fashionable mobile phone, it was loved by the public, especially business people, with its full keyboard button design.

  BlackBerry Passport is a full keyboard + touch model launched by BlackBerry in 2014. This model is as square as its name, like a passport. At the same time, the machine also retains the classic physical keyboard of BlackBerry mobile phones and adds touch sensing function. If the user swipes on it, they can also control the screen to swipe, which is very unique.

  However, at that time, BlackBerry was already a bit powerless towards the market, and even its target business group had already fallen into the arms of other camps.

  It is undeniable that in the era of large-screen touch, a large screen can indeed bring better display effects, but for those Weibo fanatics with a single thumb, the QWERTY physical full keyboard also has many advantages in terms of typing efficiency.

  The advantage of the full keyboard is that it greatly improves the efficiency of text input, and the fingers can be "danced" on the mobile phone, which makes many people feel very happy.

  For most business people and Weibo users, a physical full keyboard is obviously more popular.

  Although it is said that after entering the era of smartphones, due to problems with corporate strategy, BlackBerry’s smartphones have never been able to keep up with the trend, and eventually BlackBerry gave up the smartphone market.

  However, the release of the BlackBerry KEYone two days ago has brought many BlackBerry fans back to the classic all-keyboard era. Compared with many large touchscreen phones, the BlackBerry KEYone is a very niche product.

  But the dedication to classic design will make this full-keyboard phone find its own market, and it will also win the favor of business people.

  Meizu mBack waist round button, achieving an interaction that Apple has never achieved

  From the first generation iPhone, to now the seventh generation iPhone, Apple has only retained a physical button for returning to the home page, in the most should solve the problem, Apple can only add gesture operation on the screen to solve.

  Jobs once wanted to add physical buttons to the iPhone in order to improve the user’s control experience, but he failed to realize his wish.

  However, Meizu has come up with a better solution – mBack. Among the various innovative interaction patterns of today’s smartphones, there is no doubt that the oval "waist circular button" – mBack, which is full of creativity and warmth, and the feeling of "I can’t go back after using it", have long become the classic logo of Meizu mobile phones.

  Friends who are familiar with Meizu should know that as early as 2009, this "waist round button" had appeared on the Meizu M8, and it was hailed as the most innovative and brave design at that time.

  It was not until the release of the Meizu Note 2 in 2015 that mBack returned to the public eye, and this return has made this design quickly popular, not only applied to Meizu’s mobile phones, but also surprisingly, this classic mBack has appeared on other mobile phone brands.

  mBack integrates many functions into the Home button. Not only do we have the familiar functions of tapping back, pressing the Home button to return to the desktop, swiping left and right to call out multiple action sheets, etc.

  In addition, today, when fingerprint recognition has basically become popular, this waist-shaped Home button also integrates the functions of fingerprint unlocking and fingerprint payment. It can be said that Meizu has realized the three buttons of an Android phone with one button. Not only is it comfortable to use, but the appearance improvement is also one of its meanings.

  The surface of mBack seems to be the birth of Meizu’s continuous "competition" with the Home button, but behind it is the continuous exploration and innovation of user experience.

  Many people say that iPhone a Home is perfect, while Meizu is increasing the cost of user experience. When you really use mBack, simple interaction logic is enough to change you.

  Write at the end:

  Due to the limited space, there are still many classic mobile phone designs that I will not list here. I believe that many people will recall the mobile phones we have chased in the past after seeing the classic designs of these mobile phones.

  When smartphones have gone through the era of savage growth, there are fewer and fewer designs that can make our eyes shineThe design of mobile phones has undergone tremendous changes since its inception, and the future will continue to change. What kind of mobile phone designs will emerge in the future?

  Let’s talk about it.

K Financial Report | NIO (Part 1): Sales revenue has risen, not only is there no profit, but the loss is even greater

The more cars are sold, the higher the income, but when can the loss stop?

On the evening of April 2, NIO disclosed its delivery performance for March and the first quarter. The next day, NIO’s Hong Kong stock price rose by 2.14%, but it fell by 7.63% and 5.6% respectively in the following two trading days. Its US stock price fell for three consecutive trading days.

Coincidentally, when NIO disclosed its 2022 earnings and February sales in early March, the first feedback from NIO’s dual-stock was equally optimistic. So how did NIO perform in March and the first quarter? What about its performance in 2022?

The first quarter of the first quarter met expectations, and the sales volume was "among the best"

Data show that in March, NIO deliveries were 10,400, an increase of 3.94% year-on-year, down 14.63% month-on-month; among them, 3203 high-end smart electric SUVs were delivered, and 7175 high-end smart electric cars were delivered. In the first quarter of this year, NIO deliveries were 31,000, an increase of 20.46% year-on-year.

In terms of industry level, whether in March or the first quarter, among several new power car companies, NIO’s performance can be regarded as "among the best". In addition to being led by Li Auto, Nezha, Xiaopeng, Zero Run, etc. were all left behind by NIO. It is worth mentioning that the ideal sales volume in March was twice that of NIO.

However, once upon a time, the throne of the new power delivering the championship has been firmly occupied by NIO. Whether the future NIO can regain the championship throne is uncertain, but it seems unlikely this year.

This can be seen from the annual sales target and current sales performance of NIO and Ideal 2023: the former’s goal this year is 250,000 vehicles, the first quarter sales of 31,000 vehicles, to complete the annual sales target of 12.4%; while the latter’s goal is between 250,000 – 300,000 vehicles, the first quarter sales of 52,600 vehicles, to complete the annual sales target of 21.04% -17.53%.

From the current data performance, NIO has suffered a lot.

It is worth noting that although NIO has achieved its sales target for the first quarter of this year, it can only be said to be a near miss.

According to NIO’s previous expectations in the 2022 annual performance report, its delivery volume in the first quarter of this year will be between 31,000 – 33,000 vehicles, an increase of about 20.3% -28.1% year-on-year. It can be said that NIO completed the delivery task in the first quarter.


"The image is from the NIO announcement."

In addition, NIO expects revenue guidance for the first quarter of this year to be 10.62 billion – 11.54 billion yuan, an increase of about 10.2% -16.5% year-on-year. But there is no clear guidance for earnings expectations.

However, it may be reasonable. After all, NIO, which saw a 33.97% year-on-year increase in sales in 2022, has not achieved profitability despite a significant increase in revenue. Instead, its losses have further expanded.

Sales revenue has skyrocketed, so why are there more losses?

According to the financial report disclosed by NIO, in 2022, NIO sales reached 122,500 vehicles, an increase of 33.97% year-on-year; revenue reached 49.269 billion yuan, an increase of 36.34% year-on-year.

From the perspective of sales and revenue data, both have reached new highs, and NIO’s performance last year seems to be good. However, in the face of both sales and revenue growth exceeding 30%, NIO’s overall profitability not only did not rise, but its losses further expanded.

The financial report shows that NIO’s net profit attributable to the parent last year was a loss of 14.559 billion yuan, 10.572 billion yuan from the loss in 2021, an increase of 37.71% year-on-year.

At the same time, NIO’s bicycle net profit also changed from a loss of 115,600 yuan in 2021 to a loss of 118,900 yuan in 2022. That is, in 2022, NIO lost nearly 120,000 yuan for every car sold.

In addition, NIO’s net loss reached 14.437 billion yuan last year, compared with the net loss of 4.017 billion yuan in 2021, and the loss expanded by 2.6 times.

The question is, sales are rising and revenue is increasing, so why are you losing more and more money? Where is the money being spent?

From the financial report, the two largest expenses of NIO are sales costs and research and development expenses, which alone cost nearly 55 billion yuan, directly exceeding revenue.

Specifically, in 2022, NIO’s sales cost reached 44.125 billion yuan, an increase of 50.5% year-on-year. This is not unrelated to last year’s "expensive electricity" and the large-scale laying of replacement stations, charging stations, charging piles, etc., which has become a direct cause of dragging down NIO’s profitability.

In 2022, affected by the skyrocketing price of lithium carbonate, battery costs skyrocketed simultaneously, which also caused the cost of new energy vehicles to rise sharply, which in turn led to a sharp drop in automotive gross profit margins. According to the financial report, NIO gross profit margin has dropped from 20.1% in 2021 to 13.7% in 2022.


"The image is from the NIO announcement."

NIO’s R & D expenses last year were as high as 10.836 billion yuan, up 136% year-on-year from 4.592 billion yuan in 2021, accounting for nearly 22% of revenue. Whether it is from the investment amount or the proportion of revenue, it can be regarded as a big deal in the automotive industry, which shows NIO’s emphasis on R & D.

You know, Li Auto and XPeng Motors invested 6.78 billion and 5.215 billion yuan in research and development last year, respectively, while accounting for 14.97% and 19.42% of revenue respectively.

To sum up, NIO’s sales revenue has increased, but it still loses money "for a reason", but for a for-profit company, this is obviously not "reasonable", but exposes its lack of cost control and profitability.

So, is the NIO that loses money really bad? Please continue to pay attention to "Automotive K Line", and we will look for answers in the next article of the NIO 2022 financial analysis article.

How can one person manage 2,000 acres of land?

On the big screen, each field has its own exclusive information and digital code, and can learn about planting information and the latest situation of crop growth and environment in real time. It can also give production operation plans based on soil, weather, and crop growth data through artificial intelligence algorithms, so as to achieve accurate implementation.

This is the "three-yuan farm intelligent system" developed by the Chongqing Shuyun Smart Agriculture Science and Technology Academy of China Agricultural University (hereinafter referred to as "Shuyun Science and Technology Academy"), which has been rooted in Chongqing for more than four years, and has brought changes to Chongqing Banan Shengtian Village, Dianjiang Biqiao Village, Rongchang Shabazi Village, etc.

One person can easily manage 2,000 acres of land

In Shengtian Village, the 2,000-acre grain and oil base here is very "smart" because it has a smart grain and oil planting management system. From planting seedlings on cultivated land, spraying irrigation to harvesting, the whole process only needs a computer and a system to realize remote management.

From the large-screen data monitoring page, you can not only see the distribution of fields and the planting area of various crops, but also monitor the real-time picture of each field, as well as the temperature, humidity, and moisture content of the soil at different levels.

"After the crops are harvested, the relevant products can also be standardized and traceable on this system, ensuring the quality and safety of agricultural products." Zhu Feng, the relevant person in charge of the grain and oil base, introduced that each batch of products can see the environmental data of its origin and production process through the QR code. For consumers, the whole life process of agricultural products is completely transparent.

The digital landscape is clear on the screen. Photo by interviewee

It is understood that to ensure the standardization of the quality of agricultural products, the teachers and students of Shuyun Science and Technology Institute introduced the concept of industrial ERP management, developed farm management Enterprise Resource Planning, condensed the "three-yuan farm intelligent system", and standardized production management of the whole process. The field is equipped with multiple sets of Internet of Things devices, including sensors, weather stations, cameras, edge computing devices, etc., which turn the situation in the field into data, and digitize the farm to a large screen at the first time. One person can manage more than 2,000 acres of land. At present, the technology has been applied in more than 10 farms in Chongqing.

Book agricultural machinery homework like "online car-hailing"

During the spring ploughing season this year, Jietingyan, a villager in Helu Village, Shilong Town, Banan District, experienced the efficiency and convenience of "one-click order" for agricultural machinery services for the first time. "After I placed an order on the online platform, someone replied to me in a few minutes, and the machine came to the field to work the next day!"

Agricultural industry Internet platform "Yunjian". Photo provided by respondents

The online platform on which Jietingyan placed the order is the "Yunjian · Agricultural Industry Internet Platform" (hereinafter referred to as "Yunjian"). During the research process, the teachers and students of Shuyun Science and Technology Academy designed and cooperated with enterprises to develop the "Yunjian" platform for agricultural materials, agricultural machinery, agricultural technology and other issues reported by farmers, mainly providing production, marketing, and other industrial chain services.

Among them, "Yun Agricultural Affairs" gathers most of the agricultural machinery socialization service teams in the region, and farmers can book agricultural machinery operations and full hosting at any time like "online car-hailing"; "Yun Agricultural Materials" provides agricultural materials collection and distribution services, which reduces the cost of agricultural materials; "Yun Production" provides planting and breeding digital management tools; "Yun Experts" can ask experts agricultural technology questions online or request on-site guidance.

In addition, there are more than 10 agricultural services such as "Yun Adoption" and "Yun Service" to jointly empower the regional agricultural industry.

At present, the platform has settled in 24 service organizations and more than 200 pieces of agricultural machinery information in Banan District, and nearly 130 agricultural machinery operators provide operation services on the platform. Since its launch, a total of 34,307 mu of operation area (including high-standard farmland) has been released, and the order amount is more than 3.3 million yuan.

Detailed explanation of the four major highlights of Hongmeng OS! Huawei’s ambition is not just mobile phones, but "unified rivers and lakes"

  At the Huawei Developers Conference, held today in Songshan Lake, Dongguan, Huawei’s consumer business officially launched its new microkernel-based distributed operating system for all scenarios – Hongmeng OS.

  Yu Chengdong, CEO of Huawei’s consumer business, said in the main speech that in the traditional model of the past, the emergence of each new form of end point will be accompanied by the birth of new operating systems. "Whether it is in the PC era, the mobile Internet era, or the Internet of Things era that 5G is about to give birth to, different eras will give birth to different operating systems." Therefore, in the face of the upcoming era of full-scene intelligence, "there should also be corresponding operating systems." Yu Chengdong said bluntly: "With the advent of the era of full-scene wisdom, Huawei believes that it is necessary to further enhance the cross-platform capability of the operating system, including the ability to support full-scene, across multiple devices and platforms, and the ability to deal with low-latency and high-security challenges. Therefore, the embryonic form of Hongmeng OS has gradually formed. It can be said that the starting point of Hongmeng OS is different from Android and iOS. It is a brand-new microkernel-based distributed operating system for all scenes, which can meet the requirements of smooth experience of all scenes, architecture-level trusted security, seamless collaboration across end points, and multi-end point deployment at one time. Hongmeng should be born in the future."

  According to him, as early as ten years ago, Huawei began to lay out Hongmeng OS, and now with the continuous improvement of Huawei’s full-scene smart life strategy, Hongmeng OS will be the product of Huawei to meet the arrival of the full-scene experience era, play its lightweight, small and powerful advantages, take the lead in applying smart watches, smart screens, in-vehicle equipment, smart speakers and other intelligent end points, and strive to build a cross-end point integration sharing ecosystem, reshape a safe and reliable operating environment, and create a new experience for consumers.

  Four highlights of Hongmeng OS

  According to Yu Chengdong, the original intention of Hongmeng OS is to meet the high-standard connection requirements of full-scene intelligent experience, and Huawei has proposed a system solution with four major characteristics for this purpose.

  1. Distributed architecture for the first time for end point OS, enabling seamless collaborative experience across end points

  Hongmeng OS "distributed OS architecture" and "distributed soft bus technology" through the public communication platform, distributed data management, distributed scheduling capabilities and virtual peripherals four capabilities, the corresponding distributed application of the underlying technology implementation difficulty of application developers shield, so that developers can focus on their own business logic, like the development of the same end point to develop cross-end point distributed applications, but also enable end consumers to enjoy a strong cross-end point business collaboration capabilities for the use of scenarios to bring a seamless experience.

  2. Determine the natural fluency of the delay engine and high-performance IPC technology implementation system

  Hongmeng OS solves the problem of insufficient performance of existing systems by using two technologies: determined delay engine and high-performance IPC. Determined delay engine can allocate task execution priority and time limit in the system before task execution. High-priority task resources will be prioritized to ensure scheduling, and application response delay will be reduced by 25.7%. The small structure of Hongmeng microkernel greatly improves the performance of IPC (inter-process communication), and the process communication efficiency is 5 times higher than that of existing systems.

  3. Reshape end point device trusted security based on microkernel architecture

  Hongmeng OS adopts a new microkernel design, which has stronger security features and low latency. The basic idea of microkernel design is to simplify the kernel function, implement as many system services as possible in user mode outside the kernel, and add mutual security protection. Microkernels only provide the most basic services, such as multi-process scheduling and multi-process communication.

  Hongmeng OS applies microkernel technology to Trusted Execution Environment (TEE) to reinvent trusted security through formal methods. Formal methods are effective means to use mathematical methods to verify that the system is correct and free of vulnerabilities from the source. Traditional verification methods such as function verification and simulated attacks can only be verified in selected limited scenarios, while formal methods can verify all software running paths through data models. Hongmeng OS applies formal methods to end point TEE for the first time, which significantly improves the security level. At the same time, because the code volume of Hongmeng microOS kernel is only one thousandth of that of Linux macro kernel, its probability of being attacked is also greatly reduced.

  4. Support one development, multi-terminal deployment through unified IDE to achieve cross-end point ecological sharing

  Hongmeng OS relies on multi-end point development IDE, multi-language unified compilation, distributed architecture Kit provides screen layout controls and automatic adaptation of interaction, supports control drag and drop, and visual programming for preview, so that developers can efficiently build multi-end automatic running apps based on the same project, realize true one-time development, multi-terminal deployment, and realize a shared ecosystem between devices. Huawei Ark Compiler is the first static compiler to replace the Android virtual machine mode, allowing developers to compile high-level languages into machine code at one time in the development environment. In addition, Ark Compiler will support multi-language unified compilation in the future, which can greatly improve development efficiency.

  The past and present life of "Hongmeng" OS

  In 2017, Hongmeng Kernel 1.0 completed the technical verification.

  In 2018, Hongmeng kernel 2.0 was applied to end point TEE

  In 2019, Hongmeng OS 1.0 was completed, based on the open-source framework, in which Huawei self-developed in key modules, using distributed architecture and ARK compiler. Determine the delay engine, launch TEE microkernel formal verification, multi-end point development IDE (Beta), and currently Hongmeng system will be applied to smart screens.

  In 2020, Hongmeng OS 2.0 is about to appear, the kernel and application framework are self-developed, the general micro-kernel architecture, high-performance graphics stack are launched, multi-language unified compilation, multi-end point development IDE, meet the car standard, and applied to innovative domestic PC, watch/bracelet, car machine and other products.

  It is expected that by 2021, Hongmeng OS 3.0 will complete soft and hard collaborative optimization, vertical acceleration file system, software and hardware collaborative high-performance IPC, and be applied to audio headphones. After 2022, Hongmeng system will be applied to VR glasses and other devices.

  Explanation of terms

  What is a microsystem?

  The micro kernel is a stripped-down version of the kernel that provides the core functions of the operating system. It is designed to increase portability in a small memory space and provides a modular design to allow users to install different interfaces, such as DOS, Workplace OS, Workplace UNIX, etc. New operating systems such as IBM, Microsoft, the Open Software Foundation (OSF), and the UNIX Systems Laboratory (USL) have all adopted the advantages of this research.

Cancel taxi operating royalties in many places, or force them to reduce "molecular money"

Cancel taxi operation royalties in many places or force them to reduce "molecular money"

  China News Service, Beijing, March 26 (reporter, Li Jinlei) Taxi reform is blossoming at the local level, and exploration is moving forward. China News Service (WeChat official account: cns2012) reporter noticed that Shenzhen, Suzhou, Wuxi, Changzhou, Xuzhou, Nanchang, Nanjing, Ningbo, Jinhua, Hangzhou, Yiwu, Wuhan and other more than 10 cities have successively cancelled the paid use fee for taxi operation rights, and implemented free use of taxi operation rights.

  The free use of taxi operating rights has become a trend

  In October last year, the Ministry of Transport issued the "exposure draft" on deepening reform and further promoting the healthy development of the taxi industry, proposing to gradually implement restrictions on the period of operation rights and free use. All new taxi operation rights shall be used free of charge, and the main business entity shall not be changed. Local governments shall not introduce new policies on the paid use of operation rights. Where the paid use of operation rights has been implemented, the city people’s government shall consider factors such as fair competition in the market, formulate a scientific and reasonable transition plan, and gradually cancel the paid use fees.

  Recently, Shenzhen proposed to implement the reform of the taxi industry and realize the free use of operating rights, which attracted attention. China News Service reporters found that in addition to Shenzhen, since this year, Suzhou, Wuxi, Changzhou, Xuzhou, Nanchang, Ningbo, Jinhua, Yiwu and other cities have also implemented the free use of taxi operating rights.

  Among them, since January 1, 2016, Ningbo and Jinhua have cancelled the collection of paid use fees for urban taxi operation rights, and Yiwu has also cancelled them all. Nanchang also made it clear in February that it will stop collecting paid use fees for taxi operation rights from this year, and will refund the paid use fees for taxi operation rights actually collected in advance after January 1, 2016.

  Since March 1 this year, Suzhou City, Wuxi City, Changzhou City (excluding Jintan District), and Xuzhou City in Jiangsu Province have stopped collecting paid use funds for taxi operating rights, and implemented free use of operating rights.

  Earlier, Hangzhou, Nanjing, Wuhan and other cities have introduced policies to stop collecting paid use fees for taxi operation rights from 2015. Among them, Hangzhou also made it clear that the operation rights of taxis are 6 years each.

  Liu Xiaoming, director of the Department of Transport Services of the Ministry of Transport, said at a press conference during the National Two Sessions this year that the taxi reform has a very clear direction, that is, the right to operate taxis should be free of charge and limited, with the aim of enabling taxi services to enter a virtuous circle and to obtain the right to operate with high-quality services.

  Or will force companies to reduce "portion money"

  "I work an average of at least 10 hours a day, the first eight hours are to earn’some money ‘, and the extra two hours are really my income," a taxi driver in Beijing Yinjian told China News Service.

  Under the background of the impact of the network "special car", the number of passengers and the decline in income, whether the "part money" can be reduced is a particularly concerned issue for the majority of taxi drivers. So, does the cancellation of the paid user fee for operating rights mean that my brothers and sisters don’t have to pay "part money" anymore?

  In fact, this is not the case. The paid royalties for operating rights are collected by the government from companies, and they are only part of the "part money". Liu Xiaoming revealed that although the standards and items of "part money" vary from place to place, on the whole, it includes vehicle depreciation, insurance, maintenance fees, driver’s basic salary, social insurance, business management costs, taxes, profits, and the allocation of operating rights royalties.

  However, after the cancellation of the paid use fee for the operation right, the burden of the taxi company will be reduced, and the "part money" will have room to decline. According to media reports, there are 4040 taxis in Wuxi urban area, and the paid use fee is 8,000 yuan per license per year. The cancellation of the taxi operation right use fee is equivalent to an annual profit of more than 30 million yuan.

  The Jiangxi Daily report also pointed out that the paid use fee for a taxi in Nanchang for 8 years is more than 60,000 yuan, and the paid use fee for 5 years is nearly 40,000 yuan. The implementation of the reduction and exemption of the paid use fee for the right to operate will force the enterprise to reduce the "part money" of the contractor.

  "Part money" proposed in many places will be determined through negotiation

  After all, it is expedient to force enterprises to reduce "molecular money" by canceling the paid royalties for operating rights. How can we truly reduce "molecular money" and reduce the burden on taxi drivers through reform?

  China News Service reporter noted that the above-mentioned taxi reform exposure draft has proposed to encourage, support and guide taxi companies, industry associations and taxi drivers, trade unions to negotiate on an equal footing, reasonably determine the taxi contractor fee standard or quota task, and implement dynamic adjustments according to factors such as operating costs and freight changes.

  Some localities have also suggested that "portion money" will be determined through negotiation. On March 24, Shenzhen announced "four measures to streamline administration and decentralize power in the taxi industry to protect the legitimate rights and interests of drivers," including reforming the monthly payment quota ("portion money"), which will be determined by the company and the driver.

  Hangzhou also proposed to improve the organizational structure of taxi industry associations composed of operators and drivers, and promote the collective negotiation system of industry wages and contract fees.

  However, when it comes to negotiating to determine "part money", taxi drivers are generally worried that they are a disadvantaged group compared to enterprises, and the final negotiation result may not be satisfactory.

  In this regard, Liu Xiaoming believes that trade unions should play a very important role in negotiations. In fact, these three parties are more important, one is the trade union, the other is the enterprise’s industry association, and the other is the government, which regulates whether the enterprise has profiteering. Under such circumstances, trade unions and industry associations represent different interests, and the government plays a more regulatory and adjustment role in it. This is conducive to the healthy development of the entire industry and can better safeguard the interests of drivers. (End)
