Siheyuan: Starting from a fitter

Chapter 156 "Bragging"

In fact, during this period, many military-industrial units had strong technical capabilities. The main service target of the Institute of Semiconductor of the Chinese Academy of Sciences was the military industry. Many advanced technologies were invested in military-industrial products without the return of funds.

Our country’s economy was already tense during this period, so the investment in research and development in the later period was getting lower and lower, and the social economy could not get the support of advanced technology, which led to a vicious circle, with technology, military and economy all falling behind.

Therefore, Li Guocheng's idea is to develop new technologies and rely on steel rolling mills to transform them into industrial products to promote social and economic development until they can be exported to earn foreign exchange.

He didn't know how the country would treat the Dawn 103 computer, but he must not turn it into a one-way investment, but must find a way to make it serve the social economy.

"I support your idea, Xiao Wu. You and Wang Gong's machine tool laboratory should have a break. Next, your laboratory should focus on CNC machine tools." Li Huaide made up his mind. This is a sure-win bet.

"Okay, director." Wu Liankui didn't understand something, but he knew what he should do now.

"Director, our laboratory continues to study computers and design software for CNC machine tools. I can participate in the research of machine tools. Don't forget, I am also very familiar with machine tools," Li Guocheng said with a smile.

"Haha, yes, you are the designer of the Shuguang II machine tool," Li Huaide laughed.

On Sunday morning, Li Guocheng's family of three came to Zhao's hometown together.

The little guy who is more than 5 months old can already walk a few steps with his support. He looks like a jade carving. As soon as he got home, he was hugged by the old man at home, and he liked it very much.

Today, Grandpa and Dad Zhao did not rush into the study, but watched everyone teasing Xiao Yu'er.When it was finally their turn to hug, Xiao Yuer struggled to be hugged by her father.

Mr. Zhao used his beard to pierce Xiao Yu'er's tender face every time, so when Xiao Yu'er saw her great-grandfather, she refused very much.

After everyone played around Xiao Yu'er for a while, the three of them seemed to have completed a ritual and entered the study room with satisfaction.

The weather was getting a bit hot now, and the study that had been closed all night had a strong smell of smoke. Mr. Zhao walked to the window, opened it, stood there with his chest raised, took a few deep breaths of fresh air, and turned back to his armchair.

Father Zhao took a vest and put it on Mr. Zhao. Li Guocheng had already made tea for the three of them and placed it in front of everyone.

"Tell me about it. I heard that you have made significant progress." Mr. Zhao took a sip of tea and said with a smile.

Now Mr. Zhao is very satisfied with Li Guocheng, not to mention his ability, he also takes good care of Zhao Ting.It's a pity that he is unwilling to enter politics, otherwise the family resources will be more inclined to him.

For Li Guocheng, these are not important. As long as he can strengthen the country's shortcomings, he feels that it is not a loss to travel through time.

How can the years be quiet and good, but some people move forward with heavy burdens.

Li Guocheng, who traveled with the secret realm, felt that his mission was to strengthen China's technological shortcomings in this era.Although it is very difficult, if you do it, it is possible to succeed.Fortunately, the current results are good.

"Yes, according to the latest foreign technological development status collected by overseas comrades, I have reason to draw a conclusion that the Dawning 103 computer is the most advanced computer in the world.

Not only do we have a more advanced CPU than them, but we also have an advanced system layout. Together with the operating system, our Model 103 can be said to be a computer equipped with a human brain.

It can work tirelessly day and night, memorize large amounts of documents, perform data calculations and analysis, and assist engineers in completing complex tasks.

Such as CNC machine tools, weather forecasting, material analysis, automatic control, and even more huge military applications, such as radar automatic search, automatic tracking, automatic driving and cruising of aircraft, calculation of artillery shooting parameters, calculation of missile trajectory, automatic tracking, etc. " .

Li Guocheng was helpless. Any latest technology must be used in the military to receive the greatest attention and investment from the country.

"Oh, then tell me about how radar can automatically search and track?" Even though Mr. Zhao already knew a lot about computers, he still stayed at scientific calculations and couldn't connect it with radar.

"The working principle of our current radar is to sweep radar waves. When an object is encountered, the radar waves are fed back to determine the size and trajectory of the object. These are displayed on the screen and calculated and analyzed manually.

But if there is a technology that converts the analog signal reflected by the radar into a digital signal, and then inputs it into the computer, and the computer analyzes and calculates according to various preset algorithms, can it be faster and more accurate than manual work, and can also be tracked at the same time? Multiple goals.

Small reflections are generally ignored by humans, but if there is a data model, the computer can identify what it is based on its trajectory and speed."

The old man and Zhao's father took a breath of air-conditioning together, and the old man asked anxiously: "What do you mean, can you make this kind of technology that converts analog signals into digital signals?"

Li Guocheng nodded, "No problem, I have started to conceive now. The principle is not too complicated, and it can also turn digital signals into analog signals."

Li Guocheng boasted too much and had to say that he had already started researching AD.Now that I’ve said it, let’s continue.

"Our current communication is basically analog technology, using analog carrier technology, the transmission distance is short, and the power consumption is high. For example, telephones require many operators to switch channels manually.

However, if the sound signal is converted into a digital signal and digital encoding technology is used, lower power consumption can be transmitted farther, and automatic switching can be achieved using a computer.

What is more economical is that one signal line can accommodate more phone calls at the same time without affecting each other.These are the rules I discovered when designing computers, and then I started to associate them and found that these are all possible."

"If this can be achieved, then this computer will be too powerful and must be given greater attention," said Zhao's father with emotion.

"Our steel rolling mill laboratory will have two directions next, one is computer technology research, and the other is CNC machine tool research."

"I get angry when I talk about this CNC machine tool. Last month, we went to Xiaozhi to buy the CNC machine tool through our connections. When they knew that our country was buying it, they not only refused to sell it, but also humiliated our representatives in person."

"CNC machine tools are the future development direction. At present, small integrated circuit CNC machine tools are most commonly used in the West, commonly known as third-generation CNC machine tools. The fourth-generation CNC machine tools controlled by small computers are too expensive and insufficiently used.

We want to directly start the research on the fifth generation CNC machine tools, which is to use the Sugon 103 microcomputer for control.Information shows that the fifth generation of Western technology has not yet been launched, there is only a conceptual definition, and the key is microcontrollers and stored data."
