Chapter 122 A Preliminary Study of China’s Compound Eye Project
Tesla and Musk are trying their best to do Washington’s work in Americen. One after another, Chinese car companies have announced that they will be equipped with new generation solar technology.
And regard this as their important selling point.
Lei Jun even announced on Weibo that Xiaomi Motors will have even more amazing black technology:
“We will be equipped with advanced technologies that no one has thought of, and Xiaomi Motors will definitely bring it to everyone. Come and be surprised.”
The number of comments below quickly exceeded 1,000, and netizens’ comments were all concentrated on:
“I just want to know if I can hit 99,000? If I can, you will be the God of Thunder!”
“Jiang Cheng Is there a discount for university alumni? If there is a discount, I didn’t tell you.”
“Can you reveal what the black technology is?”
“Can you kill Wuling Hongguang?”
Everyone’s attention is still focused more on cost-effectiveness.
Friends and businessmen all tried to find out what kind of black technology it was. Among them, Xiaopeng and Li Bin, who had collaborated a lot with Lei Jun in the past and had good personal relationships, came to visit in turn.
"Mr. Lei, what big move are you going to unleash this time? Can you tell us first? Don't worry, I will never leak the secret." Xiaopeng called and asked.
Lei Jun declined: "You will know by then. There will be a press conference at the end of this year. Don't worry, there is no competition between our pricing and Xiaopeng."
These words made Xiaopeng was shocked, "Are you really planning to seize Wuling Hongguang's market?"
Generally, everyone wants to build a high-end brand first, with a price range of 100,000 to 200,000 yuan or even lower. It is really thankless. Users say they buy it, but they may not really buy it, and it drags down the entire brand image.
Lei Jun immediately explained: "You have seen our models, how can they be less than 200,000, it is a loss.
Our pricing will definitely go up, no It will go down."
Xiao Peng was relieved now. Lei Jun obviously meant to go to the price of 300,000 and go to Wei Lai: "Mr. Lei, I wish you success and wait for you. News."
Li Bin and Xiaopeng have completely different styles: "Brother Jun, Xiaomi Automobile is very popular recently, let's see when we can come and learn."
Lei Jun is one of the earliest investors in Weilai, so the two of them are familiar with each other.
“Yes, welcome, we need to learn from you. NIO has done very well in the past few years. Every time I go to the Yangtze River Delta region, the most popular new energy vehicles I see are NIO and Tesla. Damn it.
I went on a business trip to Shenhai not long ago, and I saw NIO more frequently than Tesla.”
The place where NIO’s battery swap stations are most densely populated is. It is the Yangtze River Delta region.
Battery replacement is a product that you will feel great after experiencing it, and it can relieve your battery life anxiety to a certain extent.
It is not so friendly to car companies, because it is heavy on assets and high investment. When there is a breakthrough in battery technology, battery replacement will become more and more embarrassing.
As soon as the perovskite battery technology of Guangjia Aerospace came out, everyone used solar cells to replenish energy to solve battery life anxiety, and the competitiveness of battery replacement was obviously much weaker.
So apart from Tesla, which cannot use perovskite batteries, NIO is the most uncomfortable among new energy car companies.
Fortunately, perovskite batteries are beneficial when used in power swap stations.
Li Bin said: "Will you be lucky enough to visit Xiaomi Motors then?
I have always liked cars, and I am very curious about the cars made by Brother Jun. "
Lei Jun agreed simply: "Okay, no problem. ”
In fact, Lei Jun would only let him see Xiaomi su7, and would not show him Ultra.
Li Bin happily ran to Yanjing to experience su7, and thought that this This car is far from being disruptive. I feel that Xiaomi’s promotion is too high and it will overturn sooner or later.
Domestic new energy car companies are fighting each other, just like playing Three Kingdoms
Chen Yuanguang specially treated Lei Jun to a meal before leaving, in order to help Lin Jia find a suitable position for her in Xiaomi Automobile.
“Brother, I’ll leave this matter to you.”
Lei Jun promised to leave Lin Jia a vice president position at Xiaomi Motors, and he would be mainly responsible for marketing in terms of specific responsibilities.
The reason for this consideration is that Lei Jun feels that she has potential in this area. When Chen Yuanguang was hired as the chief scientist of the Gates Global Foundation, Lin Jia's operation fully demonstrated her ability in this area. ability in this area.
In marketing, what you need most is ideas, and they must be holistic ideas.
In addition, Xiaomi itself has rich experience in marketing, and the middle management responsible for marketing will make up for Lin Jia's lack of experience.
After Chen Yuanguang finished chatting in Yanjing, he had already flashed to Chongqing to visit the Chinese compound eye project that Guangjia Aerospace invested 1 billion in.
This time, Academician Mao Ke went with him, departing from Yanjing and taking a private plane rented by Guangjia Technology to fly to Jiangbei Airport in Chongqing.
Lin Jia returned to Shenhai alone to prepare for the handover of work. "Yuan Guang, as we planned before, uses a total of 25 antenna arrays with a diameter of 30 meters, forming a radar aperture of approximately more than 600 meters.
20 radars will be deployed in the early stage, and the radars at key points are planned to be deployed after the new generation detection radar is successfully developed. ”
After more than half a year of full cooperation, Mao Ke has a new understanding of Chen Yuanguang’s strength, so his attitude has changed from being at a distance to being friendly now.
He is an academician. Over the years, he has attended academic conferences of all sizes, including the PhDs and masters he has taught, and the PhDs and masters taught by his disciples. He has met too many people, including those who are diligent and those who are talented. There are also people who are both diligent and talented.
In his opinion, Chen Yuanguang is very special. He is particularly talented. If there is a level of talent, Chen Yuanguang will definitely reach the top today. He will discuss something and give you ideas tomorrow and a detailed design plan a week later. The sample will be sent to the office of Yanjing University of Science and Technology a month later.
Mao Ke prides himself on being old. Both his talent and Chen Yuanguang's business achievements are enough for Mao Ke to make this network and pave the way for his descendants.
Chen Yuanguang was listening and thinking: "The radar optimization idea should be based on what we discussed before.
Is it possible to improve the radar's detection range and resolution by increasing its transmit power and receiving sensitivity? "
Mao Ke nodded: "Yes, improving the sensitivity of the receiver can receive weaker signals, thereby improving the detection capability of the radar. At present, the main thing is to improve the transmitting and receiving devices of the radar, and the signal processing algorithm has been improved. Several versions have been optimized.
We mentioned using AI to optimize the signal processing algorithm. Currently, there is no good idea on this, and the designed algorithm cannot meet our needs.
Since last year, our recruitment of master's and doctoral students has been geared toward computer majors, especially students who are good at algorithms
We plan to change the two professional courses for postgraduate entrance examinations this year to electromagnetics and data structures. ”
Mao Ke works at both the Institute of Electronic Radar of the Chinese Academy of Sciences and Yenching University of Science and Technology. He recruits students under the name of the Institute of Electronic Radar, while some of the teachers in his group recruit students under the name of Yenching University of Science and Technology. .
The university has more admissions places than the Chinese Academy of Sciences.
They recruited 40 masters and 20 doctoral students last year.
As for the difference between a master's degree and a PhD? The only difference is probably that PhDs are easier to exploit. Not all masters want to engage in scientific research. Some masters just want to get a diploma and then go to work.
This kind of master's degree is not good for PUA.
It’s different with a doctor. If you PUA him and then let him graduate normally, he still has to be grateful to you.
Mao Ke continued: "In addition to the radar itself, we have also optimized the radar array design this time, mainly to enhance its multi-target tracking capabilities."
This is because of asteroids You cannot have only one goal in mining. If you can be sure that this goal can meet your needs, your automatic spacecraft can go up, and your technology can bring the ore back after it goes up.
It must be screening multiple targets, and then letting the rocket bring multiple detectors up at one time, and further detecting multiple targets together, and finally confirming the target.
Such an operation process leads to higher requirements for radar, which are reflected in many aspects.
When Chen Yuanguang was working at Guangjia Aerospace, the cooperation model with various groups was that he led them to do it, and he had to tell them step by step how to do it.
Many times, without him, the entire team would have made no progress for a week.
Guangjia Aerospace is particularly dependent on Chen Yuanguang, much more than Guangjia Technology.
This is why Chen Yuanguang has always wanted to recruit experienced researchers from the Institute of Aerospace Science.
The cooperation with Mao Ke is so smooth. You set a goal and he gives you a solution. Then you tell him what problems the solution may have and how to do it better. He brings it to you. The first version of the solution is almost ready for use.
Chen Yuanguang only needs to compare it with the radar array design drawings at the end of the 21st century, think about what shortcomings there are, and then hold a remote meeting with Mao Ke to determine it.
This cooperation model made Chen Yuanguang feel that Mao was worthy of being an academician. Although his scientific research capabilities have deteriorated to the point of decline, he has reached an advanced level in project management.
“In terms of signal processing technology, we will only make specific optimizations after the subsequent core radar optimization is completed. The current main directions are adaptive filtering, target detection and tracking algorithms.
I heard from people on the project team that we are in short supply of high-performance graphics cards. Last year we started cooperating with Huawei to purchase their Ascend processors. Hiace hopes to build an AI model to solve these problems.
The current progress is limited. Let’s see if it will be better after recruiting people this year. "
"After OpenAI released ChatGPT at the end of last year, Amerikan prohibited Nvidia from exporting high-computing power graphics cards to China, causing universities to face a computing power shortage.
It seems that everyone suddenly starts to lack computing power. Old people like me often hear young people discussing computing power.
However, we have sufficient budget for this project. Even if we can’t buy NVIDIA graphics cards, we can still buy Huawei’s Ascend series. We don’t lack computing power, but we lack people. "Mao Ke joked.
Whether it is a research institute or Yenching University of Science and Technology, their recruitment is different from that of companies. It does not mean that you can recruit if you are short of people.
Either recruiting students must be included in the plan, or recruiting researchers or young teachers, there are staff restrictions.
There should be more, please give me a monthly ticket to make Crow Riwan more motivated!
