Intelligent Industrial Empire

(A book recommended by a friend, a guide for the development of an almighty local tyrant, tells a story about the growth of a tyrant.)

"That's OK, just trouble Deputy Factory Manager Yun to introduce to us..." After receiving Qin Qingshan's affirmation, Zhao Hui smiled at Yun Fei.

"As for the parameters of that system, I think President Qin has already told you, I won't say more here. Let's talk about the structure and some functions of this system." Yun Fei paused, in the meeting room I glanced around inside, shook his head, and asked several people.

"Do you have anything that can be written on, such as a small blackboard? If you can't draw some sketches or assembly diagrams, it will be more difficult to say..."

"There is one in the technical department office below, I'll bring it up..." Liang Qiang rushed out of the office because he didn't have a blackboard because he wanted to use pictures to explain to himself.After Qin Qingshan talked about the parameters of this system in Yun Fei's hands, his soul was hooked by this system.

Soon, Liang Qiang entered the meeting room with a small blackboard that was more than one meter long and about 60 cm wide, but found that there was no shelf that could support the small blackboard in the meeting room, and finally went to the next office. After moving a desk, the small blackboard stood on the desk against the wall.

"Everyone should know better than me that a CNC system is not just a system used to control machine tools. A complete system consists of three parts: control system, servo system, and position measurement system. Of course, the most important thing is the control system. Compared with the system you are designing now, the system in my hands is not only a more complete structure, but also a more reasonable design, which is more important. Yes, the function is more powerful..."

As Yun Fei said, he drew a brief structure diagram of the system on the small blackboard behind him.Although it is a simple diagram, it is clear where the various functional components are, especially the connection and location of the industrial control chip, the addition of memory, the control path of the servo system, the position control unit, the programmable controller logic unit, etc. The placement of core components is clear on the sketch.

All those who hadn't seen Yunfei's detailed design nod their heads.

A simple general diagram can tell whether the system structure is perfect or not.

"This system is not very different from foreign systems. The biggest difference is that it combines the small board structure of the American Dynapath system and the large board structure of the RBFANUC system. This not only improves the reliability of the system, but also improves the reliability of the system. The electronic unit of the vulnerable part adopts a small board structure, which makes the replacement of the board more convenient. Of course, the motherboard of this system cannot be purchased abroad. Whether we can make it in an electronic factory in China, I am not very clear about this. ......" During the year that Yun Fei was at Qingfeng Machinery, apart from managing factory affairs and copying this system, he really hadn't heard from outside sources.

Regarding the strength of the domestic electronics factories in the 1990s, he really didn't have any in mind.

Not to mention anything else, just say that the industrial control chip he transformed from Intel’s 51 series chips. Even if there is no way to produce it in China, he dare not take this to a foundry that can produce it. .Let Intel know that there will be endless troubles.After all, the set of chips he designed has a strong shadow of 8051.

There is no other way. Who calls the whole Chinese MCU research of later generations, the 51 series occupy the mainstream position!Yun Fei was originally a monk. If he had not seen many types of industrial control chips through Du Niang, he would even plagiarize Intel’s 8051 or 8031 ​​as they are. Anyway, their current type of chips is monopolized by China. .

Yun Fei's explanation made a group of old guys who have been engaged in numerical control system research for decades lost in thought.

They have been working on numerical control systems for so many years, and have been imitating foreign numerical control systems, but have been unsuccessful, let alone have their own design ideas and concepts.Now the control system their company is engaged in is only used for the upper surface of the CNC lathe, which can be said to be extremely crude, especially before the system diagram of Yunfei and the description of Yunfei.

Now they understand why Qin Qingshan, who has always been dissatisfied with others, lost his soul after seeing Yun Fei's system in the first place.If Huashu cannot come up with a system that can compete with this system, the system currently designed by Huashu will not be recognized by the market at all.Once listed, it will be abandoned by the entire market, although it is still a seller's market.No one wants to foolishly put a more complete system without using it with a variety of flaws.

Especially for those factories that purchase numerical control systems to transform ordinary machine tools for precision machining, if they have the option, they will never buy an expensive set of systems that cannot perform thread clearance compensation and has no macro program function to modify machine tools.

"In fact, the biggest advantage of this system is that it can not only control CNC lathes, but also CNC milling machines. The only difference is that when setting system parameters, set various functions, action states, and frequently used values. It's just different. It's not so much a set of systems as it is two sets of systems. When the system is used for milling processing, we can set this system as the X series; when the system is used for turning processing, we set it as the C series. Because customers have different needs and many functions are not available, we must classify our system according to customers' needs. In this way, not only our product models are more, customers will also reduce some of them because of the system. Need functions and spend less..." Yun Fei explained the biggest difference between his system and the imported system.

Imported systems have been classified according to their use, parameter settings define functions and so on, and his system can be regarded as a system assembly.When it is produced, just add a few circuit boards or reduce a few circuit boards, and then add or reduce some when defining functions, and it becomes a different control system for lathes or milling machines.

"Deputy Factory Manager Yun, we are a bit hard to understand what you are saying, especially the combination of large and small boards. There is no way to guarantee the functions and control accuracy without practice..." Zeng Hongqi said to Yun Fei These are a bit difficult to digest.

After all, although he has been engaged in CNC system research for so many years, after all, he can't compare with Qin Qingshan and Liang Qiang. It is estimated that Zhao Hui is not much better.What he needs to do now is to find out what's wrong with Yunfei's system and then bargain.

"For this, I cannot give proof. If there is a complete set of samples placed in front of you, I think you will definitely ask me to make a request without saying anything. Of course, with the samples, there will be nothing for you, that At that time, it is not what you can get with a 49% share of a company with a registered capital of 10 million plus 10 million in cash!"

How can Yun Fei fail to understand Zeng Hongqi's mind?So the speech was a bit rude, and the tone was extremely cold.His words made Zeng Hongqi feel that it was not in the subtropical April of the Pearl River Delta, but in Siberia.

"Deputy Factory Manager Yun, we all understand the value of your system. But this is only a theoretical system. It has not been tested, and no samples have been produced. Is your asking price too high? "Zhao Hui saw Yun Fei put down the chalk in his hand and sat down, knowing that he would never talk about the technology of this system now.So I started to enter my own role, and started discussing prices through the topic of Zeng Hongqi and Yunfei.

They could all understand the sketches Yunfei drew on the blackboard, especially when Yunfei drew them, he also explained various unit wiring arrangements and control methods.They did not expect that a displacement detection unit was added to Yunfei's system.

At present, the domestic numerical control research is still a bottleneck. Most people's research is on the open-loop control system. The entire system has no feedback components. The accuracy of the control depends on the accuracy of the motor and the screw.Domestic servo motors are still blank, and most of them are simple numerical control systems that study power stepper motors as actuators.Therefore, many people are ignorant about the use of servo motors, and have no experience at all. Where would they dare to design the CNC system.

Yunfei's system not only uses servo motors, but most importantly, it has displacement detection devices.The person who designed this system unexpectedly thought of installing the displacement detection device at the end of the drive screw to indirectly measure the actual position of the actuator.In this way, in the CNC machine tool processing, not only can effectively control the processing accuracy, it is easy to debug.At the same time, such a system will have better stability during operation.

Far from being comparable to the open-loop control system currently researched and designed by Huadu CNC without feedback device.

"Hehe, the price is high? Then how much do you think the price is right?" Yun Fei was happy when he heard Zhao Hui's words.

These guys who didn't appear in their own world are really not fuel-efficient lamps. They have started to lower prices before they formally enter the negotiation.

When Yun Fei was slandering Zeng Hongqi and Zhao Hui in his heart, he never thought that these guys would have to be forced by him if they were not in accordance with common sense, or even learned from him.As soon as he came, he began to put pressure on Huadu Numerical Control who were several rounds older than him!

"During this period, we have discussed many times, how many shares and how much cash should we give you for your system. Although we did not see the design drawings we believed in today, we still understand after listening to your explanation. This system is indeed relatively high-end in China. It can at least compete with some of the poorer mid-range systems exported to our country from abroad. Look at this, how about 6 million cash and 20% of the shares? , This system needs to wait for production and countless tests to know whether it can reach the design data..." Zhao Hui directly offered Yunfei a price.

The reserve price they negotiated, but the cash hasn't decreased much, and the share price has been reduced significantly.After all, Yunfei's asking price is 10 million in cash and 49% of the shares.

Everyone knows that with this system, it is not the ten million in cash that is valuable, but the shares of the company that produces and sells this system!If this system can realize all the functions proposed by Yunfei, more than one hundred sets can be sold for ten million!
