According to the current quotation of Kawasaki Heavy Industries of Japan, Siemens of Germany, Bombardier of Canada and Alstom of France, each high-speed rail is 220 million, and Siemens of Germany even offers 240 million.

Among them, the bogie, traction system, braking system, network control system, sponsored power supply system, and air conditioning system account for nearly 60% of the cost, which means that these companies quote 120 million.

Since the participation of Huaxing Group Company, it has solved the bogie, traction system, network control system, and sponsorship power supply core system, and the four domestic OEMs have focused on the production and research and development of car bodies, connectors, and axles.

Over the past year, Huaxing Group Company has used tens of thousands of engineers to develop a complete high-speed train network control system, including thousands of programs and supporting hardware, and successfully passed the European international safety level certification last month.

Moreover, this control system has the characteristics of perfect diagnostic efficacy and self-test efficacy, which is more convenient for application and protection. Not only can the software be changed independently according to the needs of users, but also the cost of the train network control system can be greatly reduced.

Huaxing and CSR Group Co., Ltd. joint venture Sifang Technology Co., Ltd. has now become the only company in China that can supply the core components of high-speed trains, and now the four domestic OEMs only need to purchase brake pads, connectors, axles, doors and other components from overseas, which can be said to greatly reduce the cost of producing high-speed trains.

The price of these parts supplied by the Sifang Group to the General Administration of Railways is 12 million US dollars, which is 20 percent lower than the quotation of these overseas high-speed train manufacturers, and it has approved that the price will be lowered every year if the purchase volume is large.

In spite of this, Huaxing group company can still get enough profits from these core components, in the previous life, the average annual market demand space of more than 70 billion yuan for the core components of high-speed trains in Huaxia, and the localization rate was less than half at that time, when Huaxing group can reach tens of billions of income every year for this business alone, entrenched in the pyramid part of the high-speed rail industry chain.

The center's high-level and more than one billion people in China have a very hungry demand for railway speed, and it is no wonder that the center can't wait to put forward this plan after the fuel cell high-speed train can run to a speed of 350 kilometers per hour.

In fact, Changke Co., Ltd., a subsidiary of CNR Group Company, and Bombardier of Canada jointly developed the Changbaishan EMU, with a design speed of only 210 kilometers per hour and a cost of nearly 100 million, but Bombardier only helped design and supply the core components, but the core skills will not be transferred.

Now that the debugging results of the Huaxia Star are so good, although most of the core skills are controlled by Huaxing Group Company, the joint venture Sifang Technology Company has also obtained the technical authorization, and the senior management is naturally extremely happy, and naturally puts their eyes on Huaxia Star.

Yang Jie also knew that the Changbaishan lost traction after updating the software last time, and pulled it back to the parking lot for a thorough inspection, but he still didn't find out what the reason was, which made the engineering skills staff of Changbai Co., Ltd. very shocked.

This is also a matter of no measures, the core skills are controlled in the hands of Bombardier, and the CNR group company has not understood this skill at all, and problems will naturally arise.

However, after Huaxing Group Company undertook most of the R&D projects of the Huaxia Star high-speed train, it made the high-speed rail project of Huaxia enter a new situation in advance, and Yang Jie was also quite complacent about this.

Through this project, Huaxing Group Company has also entered the high-speed rail industry chain, so that Huaxing Group Company's fuel cell and motor product skills have been more widely used, although it has been almost two years for Huaxing Group Company to invest more than one billion in this, and in the next few years to smash into more money, at this stage there is no income at all, but the return in the future is considerable, just a matter of time.

Besides, Yang Jie can still pay for this money.

In Vietnam, Yang Jie came to the R&D center of Huaxing Group Company in Zhongguancun.

In the laboratory of the LiDAR R&D part of the R&D Center, Yang Jie took a cylindrical LiDAR the size of a teapot in his hand and looked at it carefully.

This female doctor in her thirties with short hair introduced the details of this lidar technique on the side, her name is Tang Rong, who used to work in the Semiconductor Research Institute of the Chinese Academy of Sciences, and is now recruited to the R&D center as the chief expert, responsible for the development of lidar.

"Yang Shao, now we apply gallium nitride materials with thermal expansion coefficient is about twice that of silicon, gallium nitride materials grown and deposited at high temperature on silicon substrates tend to compress rapidly when cooling, and the grand tensile stress of the silicon substrate pulling outward is very easy to crack, and the resulting microcracks and other shortcomings seriously affect the material quality and device performance......"

"Well, this situation is also normal, I am asking the semiconductor material R&D department in Tanzhou City to develop a 4-inch gallium nitride wafer, and after the GaN wafer is mass-produced, the problem you mentioned can be easily solved, and the large-scale mass production of gallium nitride can also be realized. ”

Yang Jie nodded and said.

Now enough to make gallium nitride wafers are only Japan's Sumitomo and Hitachi cables and two companies in the United States can produce two-inch gallium nitride wafers, and now the domestic research and development of gallium nitride laser devices are based on silicon carbide and sapphire as substrates, and the defect rate of the devices produced is very high.

The lidar developed by the team led by Tang Rong was originally prepared to apply a relatively mature gallium arsenide material laser, but Yang Jie directly rejected it, although the skills of gallium arsenide materials in all aspects are already very mature, but Yang Jie will prepare to apply lidar on vehicles in the future, the application environment is very complex, and high precision is required, and the gallium arsenide laser obviously cannot meet the request.

Since the boss made up his mind to engage in laser devices made of gallium nitride materials, Tang Rong quickly adjusted his mentality, made gallium nitride laser emitters and laser power systems, and launched the first generation of mechanical lidar samples.

"Yang Shao, now we can only do 4-line lidar, the scanning accuracy is very poor, there are also interference problems, and the cost is also very high......

Tang Rong said vigilantly.

In order to develop this lidar, Tang Rong's skills have spent tens of millions of R&D funds for more than a year, and there is still a long way to go before the lidar can be put into practice.

"You don't need to think about the funding, what you need to think about is how to make the lidar scan faster, the accuracy is higher, and the radar performance is more stable. ”

Yang Jie waved his hand and said.

The research and development of gallium nitride lidar is only a practical application field of gallium nitride materials, although the research and development time is very long, it may take more than ten years to enter the automotive market, but once successful, it will not only be used in laser imaging and laser scanning, but also can be used in many fields such as car lighting and LCD screen backlight, optical fiber communication, etc., anyway, it will not lose money.

Moreover, in the application of gallium nitride materials, the progress of China and Japan, Europe and the United States is lagging behind, but the gap is not so big that it cannot catch up.

Now the Japanese side is important to use gallium nitride made of high-brightness LEDs, green LEDs, blue discs, some companies use gallium nitride high-frequency transistors to start used in mobile communication stations, communication satellites, radar and other fields, but the previous use of gallium nitride power components on sapphire substrates is expensive, it is difficult to enter the trade field, and now they are developing silicon substrates, which is also encountered considerable difficulty.

However, Yang Jie now directly asks the company's R&D part to directly develop GaN substrates, but he is ahead of the curve, and in a few years, as long as a breakthrough is made on GaN wafers, GaN power devices with high quality and high price competitiveness can be quickly obtained.

Although it is impossible to reduce the cost of devices made of gallium nitride in a short period of time, it can quickly realize industrialization by relying on the Huaxing group company's own market share in the fields of communication base stations, optical fiber communications, automotive electronics, fuel cell products, etc., which has a very big advantage over some companies that can only concentrate in a narrow market segment.

Now what material skills Yang Jie is aiming at, Huaxing Group Company will mobilize a large number of manpower, material and financial resources to concentrate on a certain field to continue to tackle technical problems, and after overcoming a certain technical difficulty, these skills will be quickly promoted in all subsidiaries of the group and some cooperative companies.

Many companies call the R&D style of Huaxing Group Company the wolf pack strategy, and they are very afraid, not only domestic companies, but also many foreign companies are very afraid.
