Chapter 768 You fight for me
There is definitely more than one solution for realizing automatic control, digital control by single-chip microcomputer, but from a popular perspective, there is no better solution than digital control by single-chip microcomputer and PLC. Analog circuit control has complex circuits, high prices, and high requirements for designers. Functional performance is often hampered by digital control systems. It is not the best choice unless necessary.
If the technology used to popularize requires people to show off their skills before it can be used normally, it proves that this thing cannot be popularized at all.
When it comes to PLC, in essence, it is a high-reliability microcontroller system, so in the final analysis, it has to be a microcontroller.
Furthermore, the single-chip microcomputer required by PLC is actually not a high-end product in terms of specifications. Once the single-chip microcomputer is solved, it will be much more convenient to develop PLC.
Gao Zhendong is very clear about the significance of microcontrollers for popular automatic control systems. In fact, the leaders and chief engineers of the 12th Machinery Department are also aware of it. Many automatic control systems only need some simple control functions, mainly to solve a problem. For many systems, as long as this problem is solved, it will be of great use. As for how complex and advanced it is, that is Not really.
For example, DJS-61, which consists of DJS-59 to C6108, is not unable to complete the function, but it is too overflowing. This overflow includes all aspects such as volume, weight, cost, function and performance, etc., so it is impossible It is used on a large scale for simple industrial control, but this microcontroller is different.
It can be used casually without feeling distressed. Even if it is not yet at the point where it is not distressing, it can at least be said to be acceptable.
So the people in the Twelve Machinery Department can be said to be overjoyed about this matter. How many stuck technical transformation projects can be launched?
Actually, the significance of this thing is not the most important to the 12th Machinery Department. Gao Zhendong was the first to invite the 12th Machinery Department, mainly because they are the main force and responsible for the promotion!
No matter which ministry or commission needs to use this thing next, it will be the work of the 12th Machinery Department.
As for the Defense Working Committee, they immediately began to consider which weapons and equipment this thing could be installed on!
At this time, they had already remembered that some comrades had reported after consulting Gao Zhendong about certain equipment.
"...Comrade Zhendong said in this regard that control devices with greatly reduced size and weight will soon be put into use..."
It turns out that this is where the words finally came to! Sure enough, it was greatly reduced!
For the Defense Industry Committee, the firmware IC plus this minimum system can be installed in a portable air defense missile.
For the Defense Industry Committee, the smallest guided weapon now is the portable air defense missile. As for the solid anti-ship missiles, there is no problem at all.
A very amazing feeling is that for the leader of the National Defense Work Committee, he doesn’t know what this thing can do when installed on those weapons, but he just feels that this is very important.
But the chief engineer is different. He can immediately come up with a lot of uses, including more complex control algorithms, higher control accuracy, more flexible guidance strategies, and stronger daily automatic detection. Maintenance capability...
It can be said that installing this thing on a guided weapon can not only improve the core strike capability, but also effectively reduce maintenance costs, and even production costs can be greatly reduced, especially the function The more complex it is, the more expensive it is to use analog circuitry to achieve the same control function.
After all, for a microcontroller, as long as the program memory capacity is sufficient, changing to an algorithm or a strategy is just a jump within the program. However, in analog circuits, it often means paying the price of a complete set of circuits.
As for the comrades of the Postal and Communications Commission, their idea is simple. Well, let’s modify the telegraph machine first, and then modify the fax machine~~~~~~
Yes, there were fax machines at this time, but a big problem was that they could not be used on ordinary telephone lines, which greatly limited their use and popularity.
But how to change it, they didn't think of it for a while. In short, as another major branch of information technology, the Postal and Communications Commission has shown great interest in the microcontroller. It is not very capable. But it’s very versatile!
What is different from them all is that as the core ministry of mechanical and electrical integration, research and production of electromechanical equipment, the chief engineer of the 11th Machinery Department is more excited than anyone else.
"General Engineer Gao, what is the production capacity of this thing now? We've taken care of it!"
He asked anxiously without caring about anything else.
No matter how cheap this thing is, there won’t be many in the early stage. The new components will definitely not be able to increase the production volume, but from what the chief engineer of the 11th Machinery Department can think of, I don’t know how much has been “used” in advance. piece.
After all, they are different from the previous ones. The first few are currently used more on production lines and production equipment. Even if the National Defense Work Committee uses them on products, the amount of their products is not large.
But the 11th Machinery Department is different. They can now think of which products will be used on a large scale to improve their capabilities, because strictly speaking, they are responsible for the research and production of electromechanical equipment. Is a big user of automatic control systems.
Therefore, for them, it can be said that they can digest as many microcontrollers as they have. At this time, there is far from overcapacity.
The chief engineer from the 11th Machinery Department came, but the leader did not have time to come over in person. After hearing the chief engineer's words, the leaders of several other ministries looked at him rather unkindly.
Huh? What do you mean? Do you want to take over the pot as soon as you arrive?
"Comrade, I know you are in a hurry, but don't be anxious yet. We still need to sit down and discuss this matter slowly." The leader of the National Defense Work Committee smiled. The leaders of the 12th Ministry of Machinery and the Postal and Communications Commission also expressed approval.
After suffering, Meng Lang was in trouble. His own leader was away. If he wanted to compete for production capacity, he couldn't compete with these top leaders. Moreover, he always tried to make things up when he opened his mouth. This time, people were alert. They couldn't get it back with just a few words.
The chief engineer of the 11th Machinery Department now regrets that the leader did not come over. The official level is overwhelming people. At this time, there is no advantage at all: "Haha, leaders, I just want to express my attention! Attention!"
The leader of the National Defense Working Committee looked at him sideways, haha, I know you attach great importance to it, but we also attach great importance to it. We are all engaged in ministry work, and no one knows who is who.
"Comrade Zhendong, this is called a single-chip microcomputer, right? This single-chip microcomputer is of very great significance. Your production capacity must be considered and arranged by the National Defense Work Committee." It immediately stunned the other companies.
Unlike most of the previous computers, which are not considered to be completely popularized and will not compete for production capacity, this thing needs to be promoted and used on a large scale, and the competition for production capacity will naturally occur.
"Cough", the leader of the 12th Machine Department coughed lightly.
By the way, this thing is produced in the 12th Machinery Department.
“Well, our department will use Factory 1274 as the basis to further expand the production scale of their integrated circuit workshop. The new production capacity is mainly used for C6108, C6110, and this single-chip microcomputer... What is the model of this single-chip microcomputer? ?Comrade Zhendong?"
"C62D08." Gao Zhendong picked up the name casually, which means a bit like 89C51, which is a tribute to the 51 series.
“Oh, it’s because it was born in 1962, and D stands for microcontroller? It’s okay.”
This work is compiled and uploaded by Liujiu Bookstore~~
"No, 62 means it is a single-chip microcomputer, and D means it only has running memory for the time being." Gao Zhendong said with a smile, he was preparing for 61 to be a general-purpose CPU , 62 is the single-chip microcomputer, and it goes on like this. This is called brand effect.
As for the microcontroller, later on, Gao Zhendong will integrate program memory on the chip, which is something like EEPROM, so the middle mark D is used to indicate the current one, which only has running memory, to show the difference.
"Oh, okay, there is also this C62D08. The new production capacity will be used for the production of these three products." Don't push me, if you push me, how much will be produced, but we have the final say.
The leader of the Postal and Communications Commission came forward at the right time: "This thing, we still need to sit down and hold a meeting to discuss it, plan it, plan it!"
In the end, several big guys discussed it and reached an agreement to hold a meeting. Not only the people attending the meeting today, but also comrades from other relevant ministries and commissions came to discuss their needs and see how this thing could be divided. The most important one among them is undoubtedly the 12th Machinery Department, after all, the production capacity lies with him.
However, Gao Zhendong gave the Defense Working Committee a wink. The leader of the Defense Working Committee looked at it and smiled, there was an ambush.
Originally Gao Zhendong wanted to wait for the comrades from the 11th Machinery Department to leave before taking out the digital signal processor chip, but then he thought about it, it would be a bit offending to do it this way, and it is not necessary anyway. It's too secretive. The comrades from the 11th Machinery Department are also senior cadres. There is no need to worry about the issue of consciousness. If you want to do it, do it in one go to avoid having to do it again later.
"Dear leadership experts, in addition to C62D08, there is another thing that I would like to introduce to you. This is not as versatile as a microcontroller, but it is still very helpful for specific tasks."
< br>Gao Zhendong said it very modestly, but no matter how humble he said it, the National Defense Working Committee and other departments immediately became energetic.
Gao Zhendong picked up a plastic box, which contained a chip about the same size as C62D08.
In fact, there are some differences in the area of the real silicon wafer DIE between the two, but Gao Zhendong uses the same size package, which is conducive to universal use in connector and circuit board manufacturing, so it seems that the two The chips are the same size and shape. If you don't look at the silk screen model on the surface of the chip, you really can't tell them apart.
"Zhendong, is this a microcontroller again? Or?" The leader of the National Defense Work Committee's eyes lit up. Now as long as it is an integrated circuit, he is very interested, and something that Gao Zhendong launched so grandly is even more worthwhile. .
Gao Zhendong nodded: "It can be regarded as a kind of microcontroller, but this microcontroller is quite special and is specially used for digital signal processing."
The general manager of the Postal and Communications Commission has not spoken yet. Gong Xian was excited.
"A microcontroller specifically used for digital signal processing? Is it the integrated result of the digital signal processing board that the Communications Institute obtained from you last time?"
