Siheyuan: The Era of Core Generation

Chapter 123 Dongfeng also needs a computer
Regardless of whether Zhao Ye can bear it or not, the order must be carried out when it arrives.Besides, haven't these people been in the car for a day?People can bear it, but Zhao Ye can't let it go.

After a hasty meal, several people set off again.When walking on the road, Zhao Ye felt sleepy.He sat in the back seat and quickly fell asleep.

He was asleep, but he was tired of the driver. While he had to listen to the leader's order to get back at dawn, he also had to listen to the leader's order not to drive too bumpy.He didn't dare to refute such inconsistent orders.Keep your eyes wide open along the way, carefully watching the road ahead, and try to avoid going to potholes.

By the time the sun came out, they had already entered the range of the base.

Zhao Ye also woke up at this time. To be honest, Zhao Ye was quite upset this night.That is to say, he has a mental space where he can immerse his consciousness to rest. Otherwise, in such a bumpy car, if he wants to fall asleep, he is a talent.

When the sky brightened, they also walked into the gate of the base research institute.The visitor didn't take him to any conference room, but went directly to the cafeteria.The soldier driving was the worst, he was so sleepy that he could hardly keep his eyes open, and had to struggle to walk to the cafeteria.At this time, even if he wanted to sleep, he couldn't sleep, and he was still hungry.

Zhao Ye was led to the computer room after finishing his meal in a flurry of wind.Here, Zhao Ye saw a few Shuguang No. [-] machines, and he had a little bit of counting in his heart.

The construction of Shuguang No. [-] machine has also been completed, and the operators here are getting familiar with the operation of this model.Everyone was engrossed in their work, and they didn't care about Zhao Ye's arrival.

"Comrade Zhao Ye, it's really hard work for you. You must be exhausted after driving all night."

While Zhao Ye was looking around, another man in military uniform came over to greet him.

"It's okay, I fell asleep in the car." Zhao Ye quickly turned around, shook hands with the visitor and said.

"There will be a small meeting in a while. It's about our Dongfeng Type II technical seminar. The leader wants you to participate. How about it? Can you hold it?" The person who came was very considerate, at least the way he spoke was very considerate.The researchers here must be very busy, otherwise they would not have picked up Zhao Ye overnight.It may be impossible for people to ask this question.

Zhao Ye was still young, so it wouldn't be a big problem even if he didn't sleep all night, so he quickly agreed and followed the man to the conference room.

Before the meeting started, Zhao Ye once again signed a confidential document, swearing that he would not reveal every word heard here, and then entered the meeting room.

The main content of the meeting is to discuss the issue of radar and guidance.Zhao Ye also listened quietly, and when he heard some questions related to himself, he began to think quietly.

His mental space once again played a role, and he used this skill with one mind and two minds. He had already mastered it proficiently as early as when he was in class.

Using the information he heard at the meeting, Zhao Ye quickly built a model in his mental space.Various technical parameters were also filled into the model by him. It only took a short time for Zhao Ye to roughly outline the research situation of these people.

For this meeting, Zhao Ye has roughly understood the difficulties and demands of the other party.In his mind, a dedicated computer is taking shape little by little.

Of course, a complete design is impossible. What he considers is how to integrate their existing technology into the needs here.

As the meeting progressed, the outline in Zhao Ye's mind became more and more clear.

"Comrade Zhao Ye, you are an expert in the field of microelectronics, do you have any good ideas about this?" A man in a Chinese tunic looked at Zhao Ye and asked.

To be honest, today's meeting was arranged before, and Zhao Ye was invited to listen to it this time. The main purpose was to let Zhao Ye understand their general work.To solve the problem in the next step, we can have a global understanding.

No one expected Zhao Ye to come up with any technical solutions just by listening to it once. He felt that it would be difficult for Zhao Ye to rush over to participate in such an event.Ask yourself, first to show how much you value Zhao Ye, and second, to hope that Zhao Ye can ask if there is anything he doesn't understand.After all, there are more people here today, and it is not easy to gather so many people together.

Zhao Ye was called, and his thoughts were withdrawn from the space. He pondered for a while, then got up and walked to the blackboard in front of him.

Everyone was a little confused by Zhao Ye's actions, and didn't know what this person was going to do.

I saw Zhao Ye walked to the front of the blackboard, picked up the chalk and began to write and draw.Several large boxes were drawn, then connected with lines, and finally markings began to be made on them.

Radar, data converters, computers, electronic gyroscopes, guidance rates, servo motors...

Everyone looked at Zhao Ye's mark and began to think in their hearts. Everyone had a feeling that Zhao Ye would definitely say something that they had never touched before.So they all clenched the pens in their hands, ready to record some of Zhao Ye's thoughts.

"Hi everyone, I just listened to your discussion, and I have some immature ideas. This is how I think about it. In my vision, it should be such a logical relationship.

The radar measures the data, and then converts the radar signal into a digital signal through a data converter, and then transmits it to the on-board computer. The computer integrates the radar data and the electronic gyroscope data to calculate the guidance of the missile in a very short time. Law, and then pass the action signal to the servo motor. "

"Comrade Zhao Ye, how to design the missile-borne computer?" a person asked.

"I think the missile-borne computer must contain at least three parts. There must be a database. You can understand it as pre-stored data, just like some formulas. Data related to radar data and its own attitude data can be used as parameters to use these pre-stored data. The formula allows the processor to calculate the guidance law in a very short time, and then control the steering gear motor to control the flight attitude of the missile according to the guidance law.

I think this way is better than the current guidance mode.Of course, I am not professional in this area, I just had such an immature idea based on the discussion just now. "

"Comrade Zhao Ye, isn't this method a bit more complicated? Moreover, the calculation of the computer also takes time. During this time, the missiles have already flown far away, and the radar data and their own attitude data have changed a lot. Can the guidance data that comes out be more accurate?" one person asked.

"The problem you mentioned exists. But no matter what kind of guidance method, this problem will not disappear. Therefore, what we have to do is to shorten this interval to the maximum." Zhao Ye replied.

"However, the efficiency of the current computer is not good. If it is fast, it will not go up, and if it can go up, it will not be fast." The man said this again in frustration.

"I don't know how much calculation you need. I don't dare to say how long the time interval is." Zhao Ye can only say this, and he really doesn't know.

"Comrade Zhao Ye, we have tested the computing speed of Shuguang No. [-]. I invite you to come here this time, and I hope you can solve our problem. You are the person who knows computers best, especially small computers. What do you think about using Shuguang No. [-] Is there any difficulty in increasing the calculation speed by one to two times?" A person sitting on the rostrum asked.

"Ugh! Have you tested Shuguang No. [-]?" Zhao Ye asked in confusion.

"Not yet. Dawn No. [-] was assembled only yesterday, and the operators are still getting familiar with it. However, Dawn No. [-] has a lot more external equipment, which makes it more convenient to use." The man said very Sincerely, it seems that I have learned about the new functions of Dawn II.

"Actually, the computing speed of Shuguang No. [-] is more than three times faster than that of Shuguang No. [-]. However, if it is to be used on missiles, the structures and processors of Shuguang No. [-] and No. [-] are not suitable. It needs to be restarted." Design. If it is only redesigned specifically for a fixed computing mode, I think it is technically possible to increase the speed to five to six times based on the Suguang No. [-]. After all, the Suguang series of computers are strictly They are not good at computing speed. They are more suitable for general computing tasks."

"You mean, can we design a computer specially for our Dongfeng missile? How long will it take you to come up with the plan and the finished product?" The people on the rostrum couldn't sit still. The purpose of Zhao Ye's invitation is to ask him to study whether there is a possibility of the Shuguang computer being loaded.

Who knew, before they mentioned it, Zhao Ye had already analyzed it all by himself.

"Of course, the missile-borne computer is actually much simpler than the Suguang computer. After all, its function is more simple. We only want to pursue high stability and high computing speed." Zhao Ye said as a matter of course.He has long wanted to tie a computer or a chip to a missile. Now that he is faced with such an opportunity, of course he cannot miss it.

He is very confident about the bomb-mounted computer.

For many days in a row, there were many telegrams between this base and the capital.Zhao Ye was finally retained to assist in the research work here.

If you want to design a bomb-borne computer, you must at least figure out the parameters of many devices.Such as radar, such as gyroscope, such as steering gear motor.These are the most basic.Of course, there are more other data, which require experts from various disciplines to study together.

After all, a missile involves many disciplines, and the discipline of physics alone also involves many branches.For example, fluid mechanics, engine, and even the vibration parameters of the projectile must be taken into consideration.
