Siheyuan: My Northeastern Farmhouse

Chapter 449: Is it possible?

"Don't call me Xiaolin, I'm an old woman!"

"Especially in front of juniors."

"This is the Gu Weijun I talked about on the phone, and he wrote this report."

Old Mrs. Lin rolled her eyes dissatisfied, sat directly opposite Chief Zhong, and handed over the report in her hand, "No, I took the time to write it after I talked to you on the phone."

"This report is very good. It provides very good theoretical support and prospects for both the future prospects of the computer industry and the forward-looking research on the communications field of the Ministry of Posts and Telecommunications."

"Oh? Is it so good? Then I have to read it carefully!" Chief Zhong put on his reading glasses and waved to Gu Weijun cordially, "Young man, Xiao Gu, right? Find a place to sit by yourself."

Then he pointed to the thermos bottle in the corner, "Pour the water yourself!" Then he pointed to the tea leaves on the table, "Try the tea leaves from my hometown in Guangxi."

"I didn't ask the office to assign me a full-time secretary. I have my own hands and feet."

"Haha, I clean the house, fetch water and meals every day, and I can also exercise!"

Chief Zhong was afraid that Gu Weijun would be restrained, so he teased Mrs. Lin, "Young man, don't be restrained. You see, Xiao Lin is very good!"

"I told you not to call me Xiaolin!"

"You are younger than me." After jokingly replying, Chief Zhong began to read the report attentively, frowning from time to time, but did not directly correct or mark the report, but wrote it down with a pen, and then wrote it down. I will check it carefully and worry about making mistakes.

Chief Zhong has been reading this report for a full hour. Sometimes when he sees the later parts, he will find the previous parts again and compare them.
After putting down the report, Chief Zhong took off his glasses, frowned slightly, closed his eyes, and slowly rubbed Qingming Point with his fingers. After a long time, he opened his eyes and began to ask questions: "Director Lin, according to what is written in this report Yes, computers in the future will be able to write letters or send messages through telephone lines?”

"That's right, and the phone lines are not the traditional lines now, but optical fibers that can accommodate more communication transmissions!"

Chief Zhong nodded slightly and continued to ask Gu Weijun: "Comrade Gu Weijun, do you think that the network that the United States is currently studying must be the future development direction. The reason is that computers can communicate with each other and data can be transmitted to each other. But computers are not mainly Is it used for calculations?”

Gu Weijun put down the tasteless teacup in his hand and solemnly replied: "Chief Zhong, judging from the current situation of the US emperor, the development of computers is changing with each passing day!"

"There is an expert in the United States named Moore. He is not just a scholar in the university, but the chief scientist of a large chip manufacturing company in the United States. He judged that at the current technological development speed of computer hardware, every 18 months, computers will Performance will increase dramatically.”

"Judging from the current application of computers by the US imperialists, they have widely applied computers to commercial companies, factories, scientific research institutions and other institutions."

"For example, when I was doing United Front work in the United States, I visited a Chinese-American super-rich man, Mr. Wang An. His personal assets now reach nearly one billion U.S. dollars, and his factory specializes in selling a "word processor." computer."

"Also, the United States now has specialized companies that use the computing power of computers to program game programs to manufacture game consoles specifically for playing games."

"Judging from the various applications of computers by the US imperialists, as the performance of computers improves again, computers will sooner or later enter ordinary households, that is, personal computers."

Chief Zhong frowned slightly, as if he did not agree with what Gu Weijun said that computers would enter ordinary households in the future, but he did not object and continued to ask: "I understand data transmission. Our Ministry of Posts and Telecommunications has been developing microwave and carrier wave communications. Work. But when you talk about using relay satellites for air and ground data transmission, why don’t you directly study the air and ground data transmission?”

"And the definition of relay satellite. How did you come up with it? Is it possible to implement it?" "It's very simple. This is a 1-to-1, 1-to-many, or many-to-many problem."

"If a single aircraft is connected to the ground for data communication, we can use or test frequency bands for data transmission, such as high frequency. However, there are also several problems that need to be solved, such as the orientation problem. The orientation observed by the aircraft is consistent with the orientation observed on the ground. sex?"

"If multiple aircraft are linked to multiple ground surfaces, will it cause interference between frequency bands? Also, what if the encryption of the frequency band is cracked somewhere?"

"Also, if we want to lock multiple target aircraft, simply using the orientation provided by ground radar can only be the most common three-dimensional, height, and orientation; but the influence of the earth's curved surface will always exist."

Gu Weijun paused, "As for the relay satellite, as the name suggests, it is a relay satellite that serves as a general navigation satellite and direct ground transmission or air transmission."

"The satellite does not need to be sent directly to a high Earth orbit. It only needs to be a few hundred kilometers away from the ground and still fly around the Earth within the atmosphere."

"And because of the low altitude, heavier satellites can be launched into the sky with the same thrust of the launch rocket! This means that the relay satellite can carry more computers and other equipment."

Chief Zhong took off his glasses and nodded to Gu Weijun, "Xiao Gu, your relay satellite is mainly for the command of the Air Force, right?"

"Including this network, it is actually used in the military to better reflect the application effect."

"As for the email you are talking about, considering the current situation in our country, we can just bring the scientists together."

After listening to Chief Zhong's evaluation of several designed computers and networks in his report, Gu Weijun couldn't help but widen his eyes and raise his heart. Why didn't these words sound particularly supportive of these projects?

If the country starts these researches at this time, it will not be overtaking in a corner, but it will be directly on the starting line. As long as these subsequent technologies do not stop, then in the 90s, China will be able to take advantage of the first wave of the Internet. The wave took off immediately, right?

When Gu Weijun thought of this, he couldn't sit still and quickly continued to express his opinion, "Chief Zhong, as I wrote at the beginning of this report, the future industrial revolution must be an information industry revolution dominated by computers."

"Our country missed the first and second industrial revolutions before. This third industrial revolution is a major opportunity for us to lead the world again!"

"You said it"

"Xiao Gu!" Old Mrs. Lin directly interrupted Gu Weijun, who was eager to express, and spoke calmly, "Let's hear what Chief Zhong has to say first."

"Well, it's a good thing that this young man is so eager to think about the country! We just need young people like you!" Chief Zhong picked up the report and shook it. "Originally, Xiaolin told me on the phone that there were problems with optical fiber and network. We have discussed it with the research department this morning.”

“It’s definitely the way forward for communications in the future.”

"However, the network in your report is different from the network in our meeting in the morning. In the morning we only discussed the issue of telephone transmission in a very narrow way. We even discussed the use of computers for program-controlled switching in your report. ”

"We are also preparing to have the technical center of the Ministry of Posts and Telecommunications start research simultaneously."

"but."
