I hope you will continue to support Hulu!

Zhao Hui went to work on the contract, but it won't work out for a while.Qin Qingshan has a lot of doubts about the system in Yunfei's hands, and Liang Qiang is more active and looking forward to it.

Under the urging of the two, Yun Fei went to his car and took the blueprint to the office, and began to explain it to several people in detail.

Now that a cooperation consensus has been reached, an equity transfer contract will be signed immediately.With an attitude of being responsible for himself, Yun Fei explained to several people in great detail this time.Explain the various functions of this system to several people separately. After Zhao Hui got out the contract, he only explained the structure of the PLC programmable controller of this numerical control system.He still hasn't produced the blueprint of the single-chip microcomputer.

For this system, the 51-bit single-chip microcomputer based on Intel's 8 series core produced by many companies in Taiwan is completely competent.Taiwan has built a lot of factories in the mainland over the years, and they don't have a technological blockade against mainland China like Europe, the United States and Japan. After all, their own technology can't get anywhere.

"For the issue of single-chip microcomputers, I hope everyone will not be too entangled. For mainland China, foreign countries only control high-end products such as 16-bits. The control of eight-bit 8051 is not too strict. How many four-bit 8031s are needed now? How much. But this system, in the key parts, the control ability of 8031 ​​is not enough. At least 8051 or a single-chip microcomputer of the same level is needed.” When Yun Fei talked about the control structure of this numerical control system that he copied, Qin Qingshan worriedly asked what type of microcontroller to choose.

In the beginning, Yunfei copied some single-chip microcomputers from later generations and synthesized a set of the most practical control chip design diagrams.But at this time, he was even more afraid to take out his own set of chip design drawings.

In China, research on single-chip microcomputers has just started.If he pushes this result to those old men again, it is estimated that there will be a problem.

A few old men are engaged in research on numerical control, which makes sense. After all, China has successfully developed numerical control machine tools in the late 50s.If it is said that those old men still have the energy and conditions to develop computer hardware while working on CNC machine tools or CNC systems, he himself does not believe it.If the old men really have this ability, they will definitely be recruited back by the country as soon as the turmoil is over.

computer.In the late 70s and early 80s, there were few talents to be found. <Structure, also known as von Neumann structure, data lines and instruction lines are time-division multiplexed, with rich instructions and powerful functions, but it is precisely because of its structure that fetching instructions and fetching data cannot be performed at the same time.Using the single chip microcomputer with this structure as the industrial control chip of the numerical control system, the control speed is limited.Moreover, the single-chip microcomputer with this structure has one of the biggest disadvantages - the price is too high.Any good piece will cost several dollars or even tens of dollars.Even so.Our system has to use this structure of single-chip microcomputer as the control core, because the operation relationship of the CNC machine tool is very complicated during operation, especially the simultaneous linkage of several axes. "Yunfei found out that these guys who work on the CNC system seem to be not very familiar with these most basic things.

How did he know that the domestic CNC system is not a guy like him from later generations.With such an ultimate artifact like Du Niang, as long as there is something you don't understand, tell Du Niang, and Du Niang will show countless results and even things you want to connect.

In the past domestic research in this area, it was very difficult to obtain an 8031 ​​chip, and there was no way for all researchers to understand it in detail.

"..." The few people in front of them who seemed to understand half understood stared at Yun Fei eagerly.

"Damn, I was defeated by you... Our system can use not only Intel's 8051 series, but Taiwan Winbond w78 I think is more suitable for our system. I won't worry about getting stuck in the future, and the price is relatively relatively It’s cheap. Of course, the quality can’t be compared with the ones developed by guys who grew up eating raw beef. But this is acceptable to our domestic users.”

Yun Fei felt that, in the sum of two lifetimes, he couldn't find anything more tiring than explaining these things to a few old men who didn't have a deep impression on him.If it wasn't because the soul came to this body, many things he browsed online in that world would appear as soon as he thought of key words, and he himself didn't know what to do.

After such a short while, Yun Fei was exhausted, after all, he was not very familiar with these things.What he is familiar with is the structure of machine tools and the operation of machining technology.The numerical control system is just a little understanding.It is really difficult to use these familiar things to fool these professional old things.

Qin Qingshan and Liang Qiang's eyes were straightened, while Zeng Hongqi was drowsy.Yun Fei took out a cigarette and handed it to Zeng Hongqi and Liang Qiang, one for each. Regardless of the two of them, he leaned back on the back of the chair to rest.Qin Qingshan doesn't smoke, Yun Fei already knew it.

"Director Yun, Winbond's chip, we are using it now, can it be used on this machine tool that can control three-axis linkage?" Qin Qingshan digested what Yun Fei just said, and saw that Yun Fei was about to fall asleep When he caught up, he asked Yun Fei eagerly.The system they assembled before, various accessories come from all over the world, as long as they can be obtained, compatible, and put together to make the system work, they are very grateful.

Now lsk9201 can no longer mess around like the systems they assembled. If the reputation is ruined, not only will I be sorry for those old people who have worked hard for this system for 30 years, but I will also be sorry for the 40.00% shares that Huashu lost.

It can be said that Yunfei's system allows him to see another world, and what Yunfei is talking about now seems to be the key to open the door that he can see but can't touch.

Qin Qingshan never thought about where Yunfei got this knowledge.He took it for granted that Yun Fei understood these things.The other two also didn't feel any surprises.Originally, Yunfei was worried that he would talk too much, and it would be hard to explain where it came from.After all, Yun Fei knows more about these things produced abroad than Qin Qingshan and other professionals.Now he doesn't want to say more, if he talks too much, he will always show his feet.

"Old Qin, Mr. Yun, the contract is ready, please take a look first..." At this moment, Zhao Hui came in with some printed contracts.

The contract is very simple, it states that Yunfei exchanged lsk9201 for 40.00% shares of Huadu CNC Equipment Co., Ltd.And 200 million in cash.Yunfei does not interfere with the company's daily operations, only acts as a technical consultant and waits for year-end dividends...

Qin Qingshan took over the contract, and after reading it, he handed it to Zeng Hongqi and Liang Qiang who were next to him. Finally, after they confirmed that there was nothing wrong with it, they signed him seriously as the boss.Yun Fei carefully read the contract word by word, and found that the contract was written in great detail, although the level of detail could not be compared with the commercial contract samples he saw on the Internet in later generations.This three-page contract was very clear about the responsibilities and obligations of both parties, so he took the pen handed over by Zhao Hui and signed his name under the gaze of several people.

Yun Fei left.He left behind a thick stack of drawings, and took away 200 million cash checks from Industrial and Commercial Bank of China, as well as 40.00% of the equity in Huadu CNC.The remaining 1000 million cash is clearly stipulated in the contract.Yunfei must assist Huadu NC to completely produce this system. After the lsk9201 sample is produced, it can achieve more than 70.00% of the functions of the drawing design, and the equity transfer contract will take effect.At the same time, spend the remaining 1000 million cash to Yunfei.

In other words, what Yunfei got now was equivalent to a deposit.

Yun Fei didn't care much about this.after all.The drawing has already indicated how to choose the various hardware of this CNC system. If it takes a few months to figure it out, Yunfei will have a headache whether he has chosen the wrong partner.

This world is no longer the world he used to be, and Huashu is not the same as the three-legged world with foreigners. Even if there is a problem, Huashu cannot produce the simplest lathe control system in a short time, so Yunfei can only I think I am unlucky.

Who told him to measure the world he was in now from the perspective of his original world!

Yunfei rejected the idea of ​​having a few shareholders stay and have dinner together to celebrate.He needs to go to Jimin Hospital to see his uncle now, and then he has to go back to Xinkaixing. It is estimated that Ren Zhiguo is molesting his secretary while cursing himself and Wang Qingfeng.

After Yun Fei left, Qin Qingshan and the others began to study the blueprint left by Yun Fei in detail.They must thoroughly study this set of drawings in the shortest possible time, then produce samples, and after the test is completed, push this system to the market.

After all, a few of them are now carrying a loan of 1000 or 900 million from ICBC, especially Qin Qingshan. According to his original shares, one person will take up a loan of nearly [-] million. If this system cannot be listed in time , put it on the market, and the annual interest of [-]% is enough to give him a headache.If he's in debt, he can't expect to come up with a CNC system.

It is now the beginning of April, Qin Qingshan and others discussed that the various tests of lsk9201 must be completed before September, and then they can seize the opportunity to make a debut at the Huadu Trade Fair, which may save a lot of promotion costs.

Of course, Yun Fei just suggested that the first system of the c-series for the lathe should be developed first according to the drawings, so as to facilitate the return of funds.Qin Qingshan and the others wanted to produce both the c-series lathe system and the x-series milling machine system at once.After all, they have also produced nearly a hundred sets of CNC systems. They know that the assembly of the system is very simple. The only complicated thing is the setting of various function parameters and the input of the PLC ladder logic control program for various controls. .

The c-series lathe system Yunfei has already left the plc ladder diagram program, and the x-series milling machine system ladder diagram program is very rare for Yunfei. After all, it is too long, and it is far from the trapezoidal diagram of the simple system he compiled for Wang Qingfeng's second-hand milling machine. as easy as a graph program.

If there is a four-axis machining center without ladder diagram program in front of Yunfei, Yunfei can only stare blankly. (To be continued..)
