Development of productivity started in 1981

Chapter 211 Untitled
"Come on, Jiankun, let's have a drink."

"Uncle, I respect you."

Wang Jiankun and his uncle were drinking, eating and chatting in a small private room in the cafeteria.

"Jiankun, can you tell me how this satellite navigation system works? I never thought that satellites could be used for navigation."

“Okay, satellite navigation has only begun to enter engineering experiments in recent years. In the past, it was very difficult to manufacture those high-precision instruments due to processing accuracy issues.

The basic principle of satellite navigation is to use the excitation frequency of electrons outside the cesium nucleus as a basic measuring scale. Its vibration frequency reaches more than 90 billion times per second, and then there is a device inside that can obtain the data of each vibration. The speed of electromagnetic waves is as high as 30 kilometers per second. The distance traveled by the signal in one vibration will be very short, so the positioning accuracy is very high. "

Wang Jiankun briefly introduced the method of satellite navigation to his uncle.

"Oh, to put it simply, it calculates the moving distance of the receiving terminal based on the time difference."

"Yes, to measure the precise time, the most important equipment is the atomic clock."

"Does that mean only your superpowers can produce such high-precision equipment?"

"Yes, at present, only my superpowers can produce it, but the United States is already working on it. According to their progress, it shouldn't take long to produce it."

"It seems that the scientific research capabilities of Americans are quite strong. Should we be able to manufacture them in the future?"

"Of course, it won't be long before we can produce it using conventional methods. I will participate in the research of conventional manufacturing methods, and I believe we should be able to manufacture it within three months."

In fact, now in northern Myanmar, because more and more new human researchers are participating in scientific research and high-end manufacturing production, the production capacity of the entire base has been greatly improved.

Now the machinery factory in northern Myanmar is able to manufacture 5-axis CNC machine tools. Wang Jiankun did not provide any assistance for the production of this machine tool. It was all developed through collaboration between people within the organization and a group of new human researchers.

This CNC machine tool has the ability of multi-axis linkage. Compared with traditional three-axis or four-axis CNC machine tools, the 5-axis CNC machine tool has the ability to move in five axes, including X, Y, Z axes and two rotation axes A and B. It can perform processing in more directions and achieve more complex processing tasks.

It also has a rotary table equipped with a worktable that can rotate horizontally and vertically, allowing the workpiece to be processed at different angles and directions, providing greater processing flexibility and diversity.

It is also equipped with a complex control system. Due to the existence of multi-axis linkage and rotary worktable, the control system needs to be able to control multiple motion axes at the same time and adjust the motion relationship between them in real time. Therefore, it needs to be equipped with a high-performance CNC system and advanced motion control algorithms to ensure processing accuracy and stability.

The processing capability of this CNC machine tool has been greatly improved compared to previous 3-axis and 4-axis machine tools.

Improve cutting state and conditions. When the cutting tool moves toward the top or the edge of the workpiece, the worktable can be rotated to maintain the best cutting state, avoiding the situation where the cutting speed of the center point of the ball end mill is 0, obtaining better surface quality, and completely processing irregular surfaces;
Shorten the production chain and cycle, perform side wall processing through spindle head deflection, reduce positioning errors, improve processing accuracy, and shorten the production chain. In the fields of aerospace, automobiles, etc., it can well solve the accuracy and cycle problems of complex parts processing during the development of new products, greatly shorten the development cycle and improve the success rate of new products;

To improve efficiency and eliminate interference, the tool axis spatial attitude angle can be controlled to complete processing requirements that cannot be met by three-axis CNC machine tools, such as impellers, blades and steep side walls of molds, and achieve short tool processing of deep cavities, effectively improve system rigidity, reduce the number of tools, avoid special tools, expand the scope of use of general tools, and reduce production costs. For some inclined surfaces, the side edge of the tool can be used to complete the side wall cutting of the part by peripheral milling, thereby improving processing efficiency and surface quality.

Currently, this machine tool has entered the mass production stage, and about 5 units can be manufactured every month. As more and more new humans are created and enter the field of precision manufacturing, the production capacity of this 5-axis linkage CNC machining machine tool will become higher and higher, and Quanjiezhen's manufacturing capabilities will become stronger and stronger.

That afternoon, Wang Jiankun continued to go to the satellite command and control hall to watch the operation of the Beidou-1 satellite after it entered orbit.

At this time, the satellite command and control hall was brightly lit, and the huge electronic screen clearly displayed the operating orbit and various parameters of the Beidou-1 navigation satellite.

A group of scientific researchers, dressed in uniform work clothes, looked focused and serious. According to the predetermined plan, they carried out a series of subsequent controls on the satellite that had already entered orbit in a tense and orderly manner.

On the control console, researchers' fingers were rapidly tapping on the keyboard, inputting various commands and data, their eyes were fixed on the screen, paying close attention to the satellite's status changes. Some researchers were communicating quietly, analyzing and discussing various data to ensure that every link was accurate and correct.

In a corner of the hall, several responsible persons are gathered together. With the rich experience and profound professional knowledge specially prepared by the brain-computer chip, they are conducting macro control and guidance of the entire control process. When encountering some key problems, they will make decisions quickly to ensure that the operation of the satellite is always in the best condition.

As time went by, various control instructions were sent to the satellite smoothly. The Beidou-1 navigation satellite operated stably in space according to the predetermined trajectory, continuously sending precise navigation signals to the ground.

The scientific researchers in the hall are still concentrating on their posts, ensuring the stable operation of the satellite. Gradually, gratified smiles appear on their faces, because they know that their efforts and dedication will make a huge contribution to the navigation business of the Quanjie Array.

By around 5 p.m., the first phase of surveying and setting up was basically completed, and Beidou-1 had established a stable connection with all ground stations. In the future, every time it reaches the measurement and control range of a ground station, it will transmit navigation information multiple times.

These ground stations play a role in calibration and correction. Scientific researchers will use the longitude and latitude coordinates of these stations as a benchmark to correct the data of Beidou-1 in the sky.

By the end of March, Beidou Navigation had completed the launch of four satellites, and the navigation test was basically completed. After many calibrations, its navigation accuracy could reach within 3 meters, which was in line with the original idea.

This first generation currently has only 4 stars, which can provide basic navigation services for Southeast Asia and the near Asia-Pacific region where northern Myanmar is located. The terminal can obtain the latitude, longitude and altitude information of its location within 5 seconds after sending a request.

However, if you want navigation services, it is not enough to have navigation satellites in the sky, you also need an electronic map and a terminal that carries the electronic map. Lang Junjian had previously made a rough electronic map, and Wang Jiankun had specially developed a terminal for this purpose, but in the end the project was shelved because it was not practical. Now that there are navigation satellites, electronic maps and terminals carrying electronic maps need to be developed.

This time, the electronic map will not be made using the method Lang Junjian used before. Wang Jiankun plans to give full play to the role of the brain-computer chip.

At present, there are more than 5 new humans in northern Myanmar and the Asia-Pacific region, and nearly 1 people have completed brain-computer chip implants. These people move around in different areas every day. The brain-computer chip will record the terrain information seen by the eyes and then upload it to the central computer. Wang Jiankun will then integrate the terrain information collected by the brain-computer chips.

The integrated map must also be vectorized to convert the graphic elements in the image into vector data so that it can be edited and analyzed.

In addition, information collection and integration are required. In addition to vectorized map data, other relevant information needs to be collected, such as enterprise user information collected by walking and vehicles, aerial photogrammetry and satellite images, call center information, etc. This information includes roads, points of interest (POI, such as restaurants, buildings, etc.), backgrounds, pictures, real-time traffic conditions, etc. Some key building models may also need to be established separately.

Once the above data is obtained, it is also necessary to convert and compile the data for testing. The produced data must be converted, compiled, and tested to ensure the accuracy and completeness of the map data.

This part requires a lot of effort. Wang Jiankun estimates that it will take about two years. In addition, detailed information may not be collected in some places, and there may only be satellite images in the end.

……

"Jiankun, why haven't you published any new papers in the past few months?"

In early April 1984, Wang Jiankun returned to BJ after a long absence. After completing the memory fusion with his clone, he first went to the department head, because the department head had already contacted his clone several times to ask him about the new paper, but the clone had always laughed him off.

"Director, I didn't reply to you before because I was doing the final research, but there was no result yet. Now I have finished it and written the paper, so I came to you to check it out."

"Oh, Jiankun, you just laughed it off when I asked you several times before. You refused to tell me your research progress when I asked you about it. What kind of research is it? Why are you so tight-lipped?"

"Director, this research result is very important. I hope it can enter the confidentiality review. If the result is confirmed, I hope it can be kept confidential."

"Oh? Entering the confidentiality review? Do you know what this means?"

"I know that after entering the confidentiality review, no matter whether the results are finally recognized, the honor I received will only be known to a few people, and it will be registered as confidential, and it may not be declassified until several years later."

"It's good that you know. You are so young. If you keep your results secret, it will have a great impact on your subsequent honors, your chance to go abroad, etc."

"Director, I have thought it through. Once this achievement is confirmed, it will be of great help to our domestic development. However, if it is made public, we may fall further behind due to our weak foundation, because foreign countries will conduct research and application based on public research data, and the application will be faster and wider than ours."

"Okay, then tell me roughly what the results are, but don't go into detail, so I can report to my superiors and have them organize a confidential review."

"It's about the study of the general solution of the NS equation. I have obtained the general solution formula. In the future, when we conduct fluid mechanics research, we will be able to greatly simplify and reduce the related simulations and actual machine experiments."

"The general solution to the NS equation, have you got the general solution formula?" When Director Zhang heard what Wang Jiankun said, he stood up in surprise, supported his hands on the table, leaned forward, and looked at Wang Jiankun fiercely, as if he had seen some incredible scene.

"That's right. The general solution formula can be applied in many engineering fields, such as aerospace, design and manufacturing of surface and underwater ships, bridges and dams, etc. As for the specific application, I can't finish it in a few words."

"Yes, yes, yes. You don't need to tell me all this in detail, Jiankun. Let me confirm with you one last time whether you are confident in your research results. I don't want you to use wrong results for confidentiality review. You should know that once you apply, many scientific research masters will put down their work to participate in the review. If it is found that your research is unsuccessful or contains major errors, your future will be almost over."

"Director, I am sure that my research is completely correct, so you can report it with confidence."

"Okay, I believe you."

Wang Jiankun's mathematics department director seemed to have made some kind of decision. He looked at Wang Jiankun deeply, then went to another office and made several calls using the red phone there.

Wang Jiankun used his superpowers to "hear" everything clearly and knew that Director Zhang was indeed notifying his superiors and told them exactly what he had just said.

"Jiankun, from now on, you will not be so free. The superior attaches great importance to the research results you have told me. You will have to accompany me from now on. When we enter the formal review stage, there will be security personnel following you."

"I understand. This achievement is indeed worth doing this." When Wang Jiankun decided to report the news of the general solution to the NS equation to the department head, he already had a plan, because he knew that the top scientists in the country understood the significance of this research result, and once the report was made, he would be protected throughout the process.

Just as Director Zhang said, that afternoon, Wang Jiankun was asked to move out of the ordinary student dormitory and move into the faculty building, with two security guards following closely behind him. In addition, he used his superpowers to discover that there were two other plainclothes security guards in the distance.

On the next day, when Wang Jiankun went out, he used his superpowers to discover that the number of plainclothes security guards nearby had reached 4 people, and every few hours, the number of security personnel increased by 2. Until 3 days later, there were as many as 16 security personnel behind him. He also used his superpowers to observe that these people had very high fighting skills and carried both long and short weapons.

During this period, Wang Jiankun only attended one briefing to talk about his research process and several key proofs.

Because this research was mainly in the application field, the authenticity was very easy to judge, so the general solution formula he wrote was confirmed to be correct not long after, and could be applied immediately.
