Chapter 275: Clouds

"How about it, Dean Guo, is there any difficulty in the power system of the gasoline engine?" Shen Danqing habitually asked Guo Dongdao beside him.

"Of course, the difficulty is, the engine system is a complex power generation and transmission system, the cooperation between the various parts requires us to invest a lot of energy and time to experiment, in addition, its operating environment is harsh, which we can not set an ideal value like other mechanical equipment, or try to be as precise as possible, it is too precise but not good, will have frequent problems. However, it is not possible to have too large part gaps, which will also affect the service life and produce serious noise, so we have to go through a lot of experiments to find an ideal intermediate value. With so many parts, the optimal clearance between each two parts is different, which is why I can't say it easy. Guo Dong took the opportunity to pour out the bitter waterway.

"Are there any other challenges? like materials. He agrees with Guo Dong's words, he knows that the development of the power system is certainly not simple, the operating conditions of each engine are different, and the engine technology of others cannot be completely copied, otherwise it will be a complete garbage engine.

In addition, it is best to customize the transmission specifically for the engine, so that the excellent performance of the engine can be fully utilized. When the public version of the transmission is adjusted, it will seriously weaken the performance of the engine.

"No, it's just that it takes time. Guo Dong said truthfully.

"I understand that it takes time, but I can't give you too much time. Therefore, you must find ways to increase the speed of research and development, such as: continuous shift experiments, more experimental engine transmissions, and so on. Shen Danqing used the narrowing method again. He is a local tyrant who only asks about the results and does not consider the cost. If you only use one engine and transmission experiment, then doing 100 or even 1,000 simultaneous experiments will definitely improve the development process. He's just such a simple and rough mind, or maybe he's from Hulan!

"Okay, boss, I know how to do it. Guo Dong saw that the boss was pretending to be brutal, so he immediately agreed.

In addition, it is worth mentioning that the engine developed this time is not one or two, but a whole series. There are 0.9 liters, 1.6 liters, 2.0 liters, 2.4 liters, 3.0 liters, 4.2 liters, 6.0 liters of micro displacement engines to large displacements. The engine with a displacement of 0.9 liters is a three-cylinder engine, the engine with a displacement of 1.6 liters and 2.0 liters is a four-cylinder engine, the engine with a displacement of 2.4 liters and 3.0 liters is a six-cylinder engine, the engine with a displacement of 4.2 liters is an eight-cylinder engine, and the last engine with a displacement of 6.0 liters is a 12-cylinder engine.

There are a total of seven engines with five different series, plus a supporting transmission assembly, so they are divided into multiple groups, each group is responsible for a single power system development task, and then a team of technical experts is responsible for the overall deployment.

Now the Institute of Mechanical Technology has recruited a large number of mechanical engineers, although they are still novices, but they are still qualified as apprentice assistants. When doing experiments, I have to start a day, record data, clean up, etc., so that the original mechanical engineer can be much lighter, and he can be responsible for more experimental topics.

All newly recruited mechanical engineers, regardless of experience, can only be used as apprentices. This is mainly because it is a special period of transformation from the machinery industry to the electronics industry, and the domestic engineers in this category are basically still in the era of the machinery industry, while Changsheng Investment Group has taken the lead and officially entered the era of the electronics industry, and is even moving towards the era of intelligent industry. Therefore, they must be unqualified when they first come, and they have to learn advanced theories and practical work experience in the electronics industry.

Shen Danqing also knew that it was impossible to have a working car power system right away, so he was not depressed on the way back to the company. As usual, it is plain and bland, and the ancient well is not wavering.

He is considering the next step of the company's development adjustment, or as before, it will definitely not. The economic environment at home and abroad is different.

The environment is different, and the next product development direction is different. Ordinary products are not urgently needed, on the contrary, high-tech products are the focus of research and development. For example: high-tech medical diagnostic equipment, cutting-edge experimental equipment, high-tech computer and network transmission equipment, wireless communication equipment and so on.

These are the equipment that the country desperately needs. It just so happened that the Electronics Research Institute and the soft news company were temporarily idle, and it was time to add more burdens to them.

However, they do not have a lot of personnel, and there are some other product development tasks, so it is impossible to swarm them all, and they can only focus on a single scientific research field. After comprehensive consideration, Shen Danqing decided that computers and network transmission equipment were the most important, and if possible, wireless communication equipment could also be added. Because these two are related industries, wireless communication equipment is only an end-end device, and the ground backbone network can also be shared with the network communication system, and the two will definitely communicate with each other in the future.

When he returned to the company, Shen Danqing asked Secretary Liu to inform Hong Tao and Lu Rucheng to come to his office, and he had a scientific research task to release.

In fact, as early as a few months ago, Shen Danqing had already asked Hong Tao and Lu Rucheng to start researching network communication equipment, but first, they all had scientific research topics at that time, and second, they did not have such professional talents.

This kind of talent can be said to be rare in Chinese mainland, and some are also research institutions affiliated to the Ministry of Posts and Telecommunications. So in fact, they didn't start their research in the past few months.

After more than half an hour, Hong Tao and Lu Rucheng arrived in Shen Danqing's office. After greetings, a set of rules and etiquette. Shen Danqing said to them: "Calling you here, there is nothing else, just to bring up the old things again, we must develop a computer network communication system."

Director Hong, a few months have passed, how many relevant talents have been recruited by your electronics research institute!"

"Boss, I'm sorry! We have only recruited three talents in optical fiber communication, and there is no talent in network communication. Shen Danqing's almost questioning tone made Hong Tao have no choice but to tell the truth.

"How did you do it? It's been a few months, and you haven't even recruited any of them?" Shen Danqing asked a little annoyed.

"Boss, network communication is an emerging industry, and there are really not many talents in this area, and we can't help it!"

"Then there is no way, you lay electronic engineers have no choice but to take the top.

Network communication is an information transmission technology that converts optical coding and electronic signals into each other. It was based on the radio cipher technology of the Second World War era. Just like the rule of length in meters, it is a kind of conversion rule set by the first scientists in this field.

In the future, the world will be a global village of information, and there will be frequent information transmission needs between countries. Therefore, at this point, we should not start from scratch, but should act according to their rules.

There must be relevant information on how the photoelectric signal is converted, but you have not had a research task in this area before, so you lack the motivation to learn this technology.

On the basis of this rule, we can develop relevant network transmission equipment. Optical fiber is also an important part of the network transmission system, which can be called the information superhighway.

As far as I know, applying a thin layer of erbium, a rare metal element, to the inner wall of an optical fiber can significantly increase the transmission distance. In information transmission, erbium is a rare metal that acts like a miniature optical pump, which can reflect and accelerate light as if it were lossless. The ability to increase transmission distances from a few kilometers to hundreds of kilometers using the optical fiber of this technology is a huge technological leap.

The second key node of network transmission is the optical pumping station, which is an optoelectronic device. There is always a time for light to decay in the process of transmission, so at this node, we need to have an optical pumping station. Amplifying and accelerating the optical signal before entering the next transmission link can also be called a repeater.

The next link is the network access points on a county-by-county basis and district-based units in large cities. This is the first integration node, and from here, it is officially connected to the backbone optical fiber network. However, it is only an access, and there is no network information storage and processing capacity, so it can be called a network communication switch.

It must be noted that the backbone optical fiber network is not only the transmission trunk of electronic network information, it is also the transmission trunk of digital television signals, digital telephone signals, and mobile phone signals. Therefore, this kind of network communication switch is also a kind of high-precision equipment, the principle is similar to the telephone exchange, but it is more complex, 10,000 doors of program control are not enough, may need 100,000 doors of program control. Here, software system technology can be used instead of pure electronic conversion technology.

The next link is the terminal processing mechanism of the network communication system, which is also the storage place of network information, which is not only the location of network address decoding, but also the location of computing, processing and storage, and the general hub, which I call the cloud.

For example, after the user registers with his real name on the computer, he can download various application software, download his favorite text, pictures and video information, which is the user's computer desktop. But unlike Microsoft's computer interface, it is not stored locally, but in the cloud. Regardless of where the user is and on which public computer device, as long as he enters his electronic identity number, his proprietary computer interface will appear on that computer screen. Specifically, if there are several members of a family, then each of them has a dedicated cloud interface. The reason why it is called the cloud is that wherever he goes, his proprietary computer interface and his private storage information can appear on the computer screen in a different place, not just on his home computer, which is the cloud. Therefore, in the future, we will only have a screensaver interface on our computer screen, and there will be no application software.

What are the benefits of the cloud? In addition to what I just said, users can call it anytime and anywhere, it can also greatly speed up the speed of information transmission, that is, the speed of uploading and downloading, because it is the information transmission between the system integration host, and its speed is a matter of course.
