Huawei HarmonyOS is officially here! Where the hell is this system？

Today, Huawei will hold the largest global developer conference in history. The HarmonyOS operating system developed by Huawei itself has become the most noticeable hot spot of this conference. Previously, Huawei registered the trademark of HarmonyOS operating system, which attracted worldwide attention. Ren Zhengfei, chairman of Huawei, said that the HarmonyOS system was not specially used for mobile phones. But for the internet of things. HarmonyOS system can control the time delay to 5 milliseconds or even milliseconds or sub-milliseconds. This operating system can be compatible with such things as autonomous driving, industrial automation, printed circuit boards, switches, smart phones and data centers.

In the 5G era, the ecological war of HarmonyOS system.

The HarmonyOS system does exist. And it is very powerful. Ren Zhengfei also admitted that HarmonyOS’s shortcoming is that its ecological environment is not as good as that of Android. Huawei’s mobile phones have a large share of overseas sales. But Google’s Android system is the mainstream in overseas markets, and it will take time for HarmonyOS to replace it overseas. But from Ren Zhengfei’s words, we can analyze that although HarmonyOS system is not specially used for mobile phones, it does not mean that it cannot be used for mobile phones.

Huawei Developers Conference

Since the registration of HarmonyOS operating system, there has been a saying that it is a branch of Android system. This is a misunderstanding. Dr Zhang Rujing, the founder of SMIC, analyzed that HarmonyOS was not a branch or modification of Android. It is a brand-new and independent operating system. It is developed for the future 5G Internet of Things.

Google also has a Fuchsia system for the 5G Internet of Things. However, the optimized version of HarmonyOS’s Ark compiler based on EMUI version 9.1 is much faster than the Android native compiler in performance. Then, Google’s Fuchsia and Huawei’s HarmonyOS system are at the same level, while the Android operating system is at a lower level.

Whether Google’s Fuchsia or Huawei’s HarmonyOS system, their ultimate goal is to replace the 4G Android system. At present, the development progress of HarmonyOS system far exceeds that of Google’s Fuchsia system. And HarmonyOS system will definitely be released before Fuchsia.

Ark compiler+HarmonyOS system, let Android experience surpass Apple.

Smartphones are a very important aspect of Huawei’s 5G business. So how can Huawei’s smartphones establish their own ecological environment as soon as possible? This problem should be discussed in two aspects.

First of all, utilitarianism: This is the most fundamental condition and opportunity for HarmonyOS system to quickly open its own ecological environment. The code of APP is not machine code but byte code. If someone develops a system, as long as the virtual machine and compilation module are compatible with the bytecode of Android APP, then the system can directly use the Android APP ecosystem.

Secondly, it is openness: Huawei opens its own Ark compiler. Let more technicians who support Huawei participate.

In this way, I believe that Huawei’s ecological environment will be established soon. Yu Chengdong announced at the Weibo that the open source Ark compiler would be released at the Huawei Global Developers Conference on August 9th.

Huawei Developers Conference

Android system is written in Java language, which is easy to learn. But it has a disadvantage, that is, it can’t communicate directly with the bottom of the system. Can only run on so-called virtual machines. To put it bluntly, the virtual machine is equivalent to a setter. First, the Android application is installed on the virtual machine, and then it is passed to the bottom of the machine.

Then the problem comes. What if the setter has a problem? The performance in Android system is the mobile phone software Caton. So, can you communicate directly with the bottom of the machine without this setter? Ark compiler solves this problem. All software of Android system can communicate directly with the bottom of the system through the compilation of Ark compiler.

Then HarmonyOS system plus Ark compiler will replace the setter of virtual machine. Why doesn’t Apple’s mobile phone get stuck in use? It just doesn’t have the setter and writes code directly for the bottom of the machine. The software of Apple’s mobile phone runs much smoother than that of Android.

Another issue worthy of attention is that Huawei’s HarmonyOS system is a microkernel. In fact, the kernel of the operating system can be a macro kernel or a micro kernel. The system development of macro kernel is difficult, and many functions with extremely high authority can be realized in it. After all, most of the functions of the operating system are in it, and solving the problem is the most direct. The Android system belongs to the macro kernel.

Because these modules have the highest authority, as long as one module goes wrong, the whole system will collapse. Microkernel, on the other hand, has few modules with the highest authority, such as task management of operating system and memory allocation and recycling management. Other modules do not have the highest authority, so even if there is an error, the system will not crash. Similarly, the development of microkernel is difficult, but the system stability is high.

At present, Huawei has officially announced the installation details and download address of the Ark compiler in the official community. In the near future, Huawei may also build an ecosystem like Apple, Microsoft and Google. (The author is a researcher at the Institute of Philosophy, China Academy of Social Sciences)

Four brands with the best engine quality： excellent choice with near-zero failure rate ＊

In the automobile industry, the engine is known as the "heart" of the automobile, and its quality directly determines the performance and reliability of the vehicle.

Director of CCTV Network Spring Festival Evening： ＂Companionship＂ is the key word, and high technology is the highlight.

11

　　Cctv news(Reporter Liu Chunyan, intern Qi Chenyan) "Year after year", CCTV Spring Festival Evening is a beautiful memory of generations of Chinese people. As the whole people step into the Internet era, CCTV Network Spring Festival Evening bridges the gap between the Internet and TV in an innovative way, presenting a unique and novel cultural landscape in the Internet era.

　　2018“CCTV Network Spring Festival Evening "will be broadcast on CCTV-3 and CCTV on the evening of February 8, 2018 (New Year’s Eve). At the rehearsal scene, CCTV reporter interviewed Xu Bin, the director of this network Spring Festival Evening.

　　"Companion" as a keyword

　　The key word of CCTV Spring Festival Evening in 2018 is "companionship". How is this reflected? Xu Bin told reporters that the biggest emotional expression of "companionship" is Sun Yang’s program. As the captain of the national swimming team, Sun Yang won two consecutive Olympic Games in London and Rio, winning glory for the Chinese people, but long-term training has to be at the expense of giving up accompanying his family. "He is a little guilty mother. But my mother always tried to stay with Sun Yang. This time, Sun Yang’s mother also came to the scene of the Spring Festival Evening, and Sun Yang was going to sing a song to her mother. " With Sun Yang’s affectionate singing, the stage background also plays the photo of Sun Yang and his mother from childhood to adulthood. Director Xu Bin also introduced that besides Sun Yang’s program, the whole party was permeated with the atmosphere of Chinese New Year from beginning to end, such as sending new year’s goods and so on.

　　"High-tech" is the highlight

　　The theme of CCTV Spring Festival Evening in 2018 is "Building a New Era of Powerful Country and Dreaming of Wisdom", with real-time connection, human-computer interaction and intelligent equipment … … Internet and scientific and technological elements run through the whole party, becoming the biggest highlight and feature of this network Spring Festival Evening.

　　IFLYTEK’s "Hearing", sogou’s "Wang Tsai", Baidu’s "Small Degree" and Alibaba Cloud’s "Urban Brain" … … Leading figures in the Internet and high-tech industries came to the scene of the Internet Spring Festival Gala with their cute and stunted "signature" products, and shared their experiences, visions and prospects for the future with netizens. "The past 2017 can be said to be ‘ The first year of science and technology ’ It is also a year of confidence for the Chinese nation. Science and technology elements run through the whole network Spring Festival Evening, and they are all local stars of our own country and independent technology of China. " Xu Bin introduced.

　　"Challenges come every year, especially this year." This sentence is very suitable for this year’s Internet Spring Festival Gala. Xu Bin told reporters that man-machine cooperation is one of the biggest challenges of this year’s Internet Spring Festival Evening. It is not easy for robots to interact with performers, hosts and audiences. "These robots should be integrated into all aspects of the party. We didn’t have much experience in this area before, and it took many times to achieve it, but I am very happy to bring a new experience to the audience."

　　"Dance Beauty" Reaches a New Height

　　In singer Summer’s performance, the white skirt covered the whole stage, reflecting the changing light and shadow, which was beautiful. Xu Bin told reporters that in the eight years since the CCTV Spring Festival Evening, the beauty of dance and lighting have been innovated every year, and the creative team is constantly challenging itself, hoping to make the characteristics of online spring and reflect national self-confidence. When asked what surprises other programs have, Xu Bin said with a smile: "Let’s sell it first, and then we’ll see. I hope that netizens will watch CCTV 2018 Network Spring Festival Evening! "

Create a new high of more than two years! Palm oil should ＂rest＂

　　Recently, the news of palm oil market resonated with the supply and demand sides, BMD palm oil reached a two-year high, and the palm oil in the inner disk rose. On October 31, the main contract of Dalian palm oil futures hit 9492 yuan/ton, a new high since the second half of 2022.

　　"Palm oil has continued to rise in recent days, hitting a new high for more than two years, mainly due to the great changes in the global palm oil supply and demand balance table, showing the expectation of ring-on-ring and year-on-year tightening." Jia Hui, an oil and fat analyst at Zhonghui Futures, said that due to last year’s El Ni? o, palm oil production in Indonesia and Colombia declined to a large extent this year. At present, the market expects that palm oil production in Indonesia will decrease by 5% year-on-year and that in Colombia by 7.7% year-on-year. While the global palm oil production is facing a year-on-year decline in 2024, the consumption and cost expectations of palm oil are rising in 2025.

　　Liu Jinlu, an analyst of Guoyuan Futures Oils and Fats, told the Futures Daily reporter that the production reduction cycle of Malaysian palm oil was advanced, and the stocking of palm oil in India boosted Malaysia’s palm oil exports. Under the weak supply and strong demand, the market expected the inventory of Malaysian palm oil to be further lowered at the end of October. In addition, Indonesia’s Ministry of Trade has imposed export license requirements on palm oil residues (usually used as biofuel raw materials) since October 25, which is also a continuation of DMO policy to some extent, or raises the export cost of palm oil in Indonesia. Coupled with the expected increase in Indonesia’s biodiesel demand under B40 policy next year, it may have a further impact on subsequent exports, thus boosting the global palm oil price center.

　　It is worth noting that a series of recent policy trends of the Malaysian government have further stimulated the bullish sentiment of palm oil. Jia Hui analyzed that under the circumstance that the market thinks that the supply of palm oil is tightening, the Malaysian government said that it would not expand seeds by logging, but increase production by increasing the yield per unit area, which means that the palm oil production in Malaysia will not increase rapidly and substantially. In addition, the Malaysian government plans to implement new palm oil export tariff rules from November 1st. According to the new rules, Malaysia’s palm oil export tariff will be increased from the recent 8% to 10%, which will further increase the import cost of domestic palm oil.

　　"In the short term, palm oil has risen to a high point of more than two years. Combined with fundamentals and technical aspects, there is a possibility of a phased correction in November." Jiang Ying, an oil and fat analyst at Guolian Futures, said that the reduction in production caused by the drought in Malaysia from January to March will end in November, and the reduction in production caused by the drought in Indonesia from September to October last year ended in July this year, and the output recovered in August. According to the relationship between extreme climate and price in previous years, palm oil prices are prone to a high inflection point when La Nina intensity is the highest. According to NOAA’s climate prediction model, this year’s La Nina peak will appear in November. Inferred from the historical law, there is the possibility of an inflection point in November.

　　"In addition, the export tax reform in Indonesia and Malaysia and the import tax reform in India have led to rising costs, and the disk has been fully priced. India’s import profits turn negative, and after Diwali on October 31, the import rhythm will slow down in stages. Indonesia’s B50 policy has been widely questioned by the market. Domestic arrivals in November will return to more than 200,000 tons. At present, the disk price has risen to a high level of more than two years, and there is a possibility of a callback technically. " Jiang Ying said.

　　Domestically, Liu Jinlu said that the increase in the price of palm oil in the producing area raised the domestic import cost, and the import profit continued to be upside down. In the third and fourth quarters, palm oil purchases were low. China imported 220,000 tons of palm oil in September, a year-on-year decrease of 58.5%; From January to September, palm oil imports totaled 2.06 million tons, down 33.3% year-on-year. From the demand point of view, the price difference between soybean oil and palm oil continued to fall, which led to the sluggish domestic palm oil consumption, and the high price suppressed the demand, and palm oil still maintained a pattern of oversupply.

　　Looking forward to the market outlook, Liu Jinlu believes that the oil plate will maintain a high consolidation trend in November, and the varieties will continue to differentiate. Palm oil has a relatively strong performance, and there is room for the price difference between soybean oil and palm oil, vegetable oil and palm oil to shrink.

　　In Jiang Ying’s view, palm oil has a long-term upward momentum, and the aging of oil palm in the producing area leads to poor prospects for production growth. The blessing of Indonesian biodiesel policy makes palm oil fundamentals tend to be tense.

　　Jia Hui suggested that there may be more profits in the short term. It is expected that the palm oil 2501 contract may be adjusted at a high level or slightly in the next one to two weeks, so it is necessary to be cautious when chasing more. From a long-term perspective, considering that palm oil in Southeast Asia entered the traditional production reduction season in the fourth quarter, marginal product declined, and short-term adjustment will not affect the long-term pattern of palm oil in the fourth quarter.

Chuangmi suffers from Xiaomi’s ＂dependence＂： 80% of his income depends on selling cameras, and Wisdom Gate is accused of IQ tax？

　　Text | Sina Technology Zhang Jun

　　Editor | Han Dapeng

　　Focus on:

　　1. AsEco-chain enterprises, creating meters and numbers, have the same joy and trouble. Relying on Xiaomi, Chuangmi Digital has created smart cameras’s explosive products and supported more than 80% of its revenue; However, the excessive dependence on Xiaomi also resulted in a low gross profit margin. Investment in research and development is also insufficient, and patent infringement lawsuits are also faced.

　　2. In order to change the dilemma of single revenue, Chuangmi Digital has launched new categories such as smart watches, sweeping robots and smart doors. Among them, the smart door has become a controversial product, and Chuangmi Digital Alliance intends to build it into the entrance of the whole house intelligence, but there are still great problems in user habits, installation and after-sales service.

　　Another Xiaomi eco-chain enterprise is going public. Relying on a camera explosion, Chuangmi Digital achieved a revenue of 1.5 billion in 2021.

　　But the thinness of products is a big problem. I don’t know if I can learn from the smart refrigerator with a screen. Chuangmi Digital Alliance takes the smart door with a screen as a key new category, trying to build it into a smart control center for the whole house. However, many users have reported that there are huge problems in the installation and after-sales of Chuangmi Smart Door, and the product demand is also in doubt.

　　Because of the excessive dependence on the millet sharing model, the gross profit margin of Chuangmi is also low, only less than 20%. Chuangmi, which sprints to the market, still faces many challenges.

　　Eighty percent of the income depends on selling cameras.

　　During the reporting period, the main products of Chuangmi Digital Alliance include smart cameras, smart watches, smart doorbells, smart doors and smart cat eyes. But in fact, it relies heavily on smart cameras products.

　　From 2019 to 2021, the operating income of Chuangmi Digital Alliance was 875 million yuan, 1.124 billion yuan and 1.532 billion yuan respectively, and the proportion of smart cameras in operating income was as high as 86.96%, 89.17% and 83.88% respectively.

　　Smart cameras products of Chuangmi Digital Alliance include indoor smart cameras, outdoor smart cameras and webcam. In the category of smart cameras, Chuangmi Digital Alliance really did a good job. According to the statistics of iResearch, the shipments of home cameras in China in 2020 and 2021 were 40.4 million and 46.5 million respectively, and the shipments of Chuangmi Digital Alliance smart home cameras in 2020-2021 were 8.04 million and 10.28 million respectively, with market share of 19.90% and 22.11%.

　　However, it is obviously not enough to rely solely on this explosion.

　　In 2020, Chuangmi Digital launched smart doorbells, smart doors, smart cat eyes, smart watches and other products; In 2021, it even entered the category of sweeping robots. We have been focusing on the creation of smart home security products, and the product line is becoming more and more messy.

　　These messy product lines have not brought smart cameras-scale income to Chuangmi Digital Alliance for the time being. In 2021, for example, smart cameras’s revenue accounts for 83.88%, smart watches for 4.33%, smart doors for 2.12%, and sweeping robots for only 0.68%.

　　Heavy dependence on Xiaomi, low gross profit margin

　　It is worth noting that Chuangmi Shulian relies heavily on Xiaomi, which is also a common problem of Xiaomi ecological chain enterprises.

　　From 2019 to 2021, the associated sales of Chuangmi Digital Alliance to Xiaomi Group were 779 million yuan, 851 million yuan and 916 million yuan, respectively, accounting for 89.09%, 75.69% and 59.79% of the company’s operating income in each period, showing a high proportion as a whole, but there is a downward trend year by year.

　　Chuangmi Digital Alliance is also aware of this problem and is making efforts to increase the sales of its own brand.

　　Xiaomi is a complex role of love and hate for Xiaomi eco-chain enterprises. On the one hand, Xiaomi eco-chain enterprises can rely on the advantages of Xiaomi’s brand and channel in the early stage to quickly turn a certain category into an explosive product; On the other hand, when these Xiaomi eco-chain enterprises grow and develop, they will not be satisfied with the low gross profit under the Xiaomi model and seek to establish their own brands instead.

　　According to the disclosure in the prospectus, under the sharing mode with Xiaomi, whether the company can make a profit depends on Xiaomi Group. For the customized products of Xiaomi in the sharing mode, Xiaomi Group will share the profits after they are finally sold through various channels of Xiaomi Group.

　　According to the data, in 2019-2021, the comprehensive gross profit margin of Chuangmi Digital Alliance was 15.50%, 17.98% and 19.75% respectively, which was generally lower than the average compared with the gross profit margins of comparable companies such as Fluorite Network, Meizhi Optoelectronics, Jimi Technology and Roborock.

　　Chuangmi Shulian explained that the gross profit margin of the company is lower than that of comparable companies, mainly because the product structure and business model of the company are different from those of comparable companies in the same industry. The company’s gross profit margin is lower than that of fluorite network. One of the main reasons is that the company’s Xiaomi mode revenue accounts for a relatively high proportion. Under the sharing mode with Xiaomi, part of the profits are shared by Xiaomi Group, so the gross profit margin is low.

　　In addition, Chuangmi Digital Alliance also has a competitive relationship with Xiaomi and other Xiaomi ecological chain enterprises. For example, in smart cameras products, Xiaomi Group not only purchases from Chuangmi Digital Alliance, but also purchases from Tianjin Hualai Technology Co., Ltd. and Shanghai Moxiang Network Technology Co., Ltd.; For example, in smart watches and sweeping robot products, Xiaomi brand also has its own products.

　　Is the wisdom gate an IQ tax?

　　In order to get rid of the dependence on smart cameras products, Smart Door is one of the key products of Chuangmi Digital Alliance.

　　First, the unit price of smart door products is higher, which is expected to bring more income; The second is that the smart door integrates many functions such as door lock, doorbell, cat’s eye, etc. At the same time, Chuangmi Digital Alliance intends to build it into an intelligent central control system for the whole house.

　　In 2020, Chuangmi Digital launched the Xiaobai Wisdom Gate H1, with a pre-sale price of 3,999 yuan and a daily retail price of 4,999 yuan. Chuangmi Digital has a 10-inch LCD screen embedded in the door, which can check the situation outside the door and control the indoor equipment.

　　This year, Chuangmi Digital Alliance has launched the BLADE STAR series of Xiaobai Wisdom Gate, with the original price starting from 12,999 yuan and the crowdfunding price of Xiaomi products starting from 7,999 yuan. This time, a 5-inch touch screen was embedded outside the door, and a 10.1-inch touch screen was embedded in the door.

　　Why put a screen on the door? The original intention of Chuangmi Digital Alliance is to use it as the entrance to control the intelligence of the whole house. In the process of intelligent landing in the whole house, with more and more intelligent devices in the house, it is difficult to control and operate only by mobile phones. Therefore, some enterprises want to add a screen control device to the refrigerator, and some enterprises want to use the TV as the control center. But in fact, no matter whether it is the door, refrigerator or TV, their control scenes are relatively simple, and it is not easy for users to develop habits.

　　From the data point of view, the sales volume of Chuangmi Digital Smart Door is not very good. In 2020, the sales volume was 4,800 units and the sales volume was 12,914,100 yuan. In 2021, the sales volume was 9,500 units and the sales volume was 32.533 million yuan. Chuangmi Digital Alliance is constantly raising the unit price of products to seek revenue growth.

　　It is worth noting that, unlike cameras, cat’s eyes and other products, the installation of smart doors is convenient, and the links involved are also very complicated.

　　Sina Technology saw on the e-commerce platform that many users who bought Chuangmi Xiaobai Smart Door H1 said that the installation service was handled by a third party, which led to frequent problems and poor after-sales service. One user said, "Don’t buy this door, it’s really rubbish and the service is rubbish!" According to his description, there are two main problems in this smart door. First, there is a problem with the door lock, and the lock core automatically rebounds, and the lock core is changed before it is used; Second, the door cover is not the right size, and there is a gap after installation, which makes it look ugly. When seeking after-sales service, it is difficult to connect the after-sales phone, and online customer service is also a unified reply, which does not solve the problem.

　　Another user also pointed out the size of the smart door. Because it does not support custom size, it is extremely ugly to install in a community with a large door. If you want to return the goods, you still need to pay thousands of yuan. "If you like smart locks and smart cat eyes, you can buy them directly. You don’t need to buy this door. It’s really rubbish after sale."

　　Even more, some users posted the post of "Xiaobai Wisdom Gate H1, Special Pit Xiaobai" on social networking sites, telling the story of being locked at home because of the door lock failure. "If, in case, any user is unfortunately trapped in a fire at home, this door will become an accomplice to murder!" He said in the post.

　　Is the moat of the accused patent infringement technology insufficient?

　　Chuangmi Digital also disclosed the risk of intellectual property litigation in the prospectus.

　　According to the prospectus, there are 15 unresolved intellectual property cases involving the defendant in the company. The cause of the case is that Hangzhou Hongyan Electric Appliance Co., Ltd. sued the company for infringing its invention patent right and utility model patent right, involving a lawsuit amount of 19 million yuan. The case involved in the lawsuit is still under trial. If the company loses the lawsuit in the future, or other parties file other lawsuits against the company in the course of business, it will have a certain adverse impact on the company’s financial status, operating performance and reputation.

　　What is the technical strength of Chuangmi Digital Alliance?

　　Data show that by the end of the reporting period, the company had 108 domestic patents, including 13 invention patents, 47 utility models and 48 design patents. It can be seen that the patents of Chuangmi Digital Link are mainly utility model patents and design patents, while invention patents account for a relatively low proportion.
