Thank you to the brothers and sisters who have always supported the gourd, today, "Intelligent Industrial Empire" finally released the first chapter of the VIP chapter, it is you who have firmly walked down the gourd. Here, Hulu bows to all brothers and sisters, thank you!

I hope you will continue to support Hulu!

Zhao Hui went to get a contract, and he couldn't get it right for a while. Qin Qingshan had a lot of doubts about the system in Yun Fei's hands, and Liang Qiang was more active and expectant.

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

Now that a consensus on cooperation has been reached, an equity transfer contract will be signed immediately. In line with the attitude of being responsible for himself, Yun Fei's explanation to several people this time was extremely detailed. The various functions of this system were explained to several people, and after Zhao Hui got the contract out, he only explained the structure of the PLC programmable controller of the CNC system. He still hasn't taken out the drawings of the single-chip microcomputer.

For this system, the 8-bit microcontroller based on Intel's 51 series core produced by many companies in Taiwan is fully competent. Taiwan has built many factories on the mainland in recent years, and they do not have a technical blockade of Chinese mainland like Europe, the United States and Japan, after all, their own technology cannot be done.

"For the problem of single-chip microcomputer, I hope you don't get too entangled. Foreign countries for Chinese mainland, the control is only 16 such high-end products, for the eight-digit 8051 control is not too strict, the four-digit 8031 is now as many as there are. However, in this system, in key parts, the control ability of 8031 is not enough. At least 8051 or the same grade of single-chip microcomputer is required. When Yun Fei talked about the control structure of the CNC system he copied, Qin Qingshan asked worriedly what model of single-chip microcomputer to choose.

Yun Fei originally copied some single-chip microcomputers in later generations, except for a set of the most practical control chip design drawings. But at this time, he didn't dare to take out his own set of chip design drawings.

In China, research on microcontrollers has just begun. If he pushes this achievement on those old men, it is estimated that there will be a problem.

A few old men, engaged in CNC research, it is reasonable, after all, China has successfully developed CNC machine tools in the late fifties. If it is said that those old men are engaged in CNC machine tools or CNC systems at the same time, they still have the energy and conditions to engage in computer hardware, he himself does not believe it. If the old men really have this ability, after the great turmoil is over, they will definitely be recruited back by the state as soon as possible.

Computer. In the late seventies and early eighties, it was almost impossible to find a few talents.

"There are two structures on the market now. It is the centralized instruction CISC and the reduced instruction RISC. CISC structure, also known as von. Norman structure, data line and instruction line time-sharing multiplexing, rich instructions, powerful, but it is precisely because of its structure that the command and data can not be taken at the same time. The use of single-chip microcomputer with this structure as the industrial control chip of the numerical control system is limited, and the control speed is limited. Moreover, the single-chip microcomputer with this structure has one of the biggest drawbacks - the price is too high. Any piece of good food will cost several dollars or even tens of dollars. Even so. Our system also has to use this structure of single-chip microcomputer as the control core, because the CNC machine tool is very complex in the operation process, especially the simultaneous linkage of several axes. "Yun Fei found that these guys who are engaged in CNC systems. I don't seem to know much about these most basic things.

Where did he know that the domestic CNC system is not like him, a guy from later generations. has 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 that you want to relate.

In the past, it was difficult to obtain an 8031 chip for this kind of research in China, and there was no way for all the people engaged in research to understand it in detail.

"......" The few people in front of him who seemed to understand whether they understood or not, stared at Yun Fei with a longing expression.

"Damn, you guys defeated me...... Our system can be used, not only Intel's 8051 series, Taiwan Winbond W78 I think it is more suitable for our system to use. You won't worry about getting stuck in the future, and the price is cheaper. Of course, the quality certainly can't compare to what the guys who grew up eating raw beef have studied. However, this is still acceptable to our domestic users. ”

Yun Fei felt that in his two lives combined, he couldn't find anything more tiring than explaining these things to a few half-old men now. If it weren't for the fact that the soul had come to this body, it would have turned out that many things he browsed on the Internet in that world would appear as long as he thought of keywords, and he himself didn't know what to do.

After a while, Yun Fei was exhausted, after all, he was not very familiar with these things. What he is familiar with is the structure of the machine tool and the operation of machining technology. CNC system, just to understand. It's really hard to fool these old professional stuff with these things that you know.

Qin Qingshan and Liang Qiang's eyes were straight when they listened, and Zeng Hongqi was drowsy. Yun Fei took out a cigarette and handed it to Zeng Hongqi and Liang Qiang, regardless of the two of them, he leaned back on the back of the chair to rest. Qin Qingshan doesn't smoke, and Yun Fei has long known the Tao.

"Director Yun, Winbond's chip, we are using it now, can it be used on this set of machine tools that can control three-axis linkage?" After Qin Qingshan digested what Yun Fei said just now, he saw that Yun Fei was about to fall asleep, and asked Yun Fei eagerly. The system they had assembled before, all kinds of accessories came from all over the world, as long as they could get it, it could be compatible, and it could make the system run together, they were very grateful.

Now LSK9201 can't mess around like the systems they assembled, and if their reputation is ruined, they will not only be sorry for the old people who have been fighting for this system for 30 years, but also sorry for the 40% of the shares that Hua Shu lost.

It can be said that Yun Fei's system made him see another world, and the things that Yun Fei is talking about now seem to be the key to open the door that he looks at but can't touch.

Qin Qingshan didn't think about where Yun Fei got this knowledge. He felt that it was natural for Yun Fei to understand this. The other two didn't feel any surprises either. Originally, Yun Fei was worried that he had talked too much and was not easy to explain where he came from. After all, Yun Fei knows more about these things produced abroad than Qin Qingshan. Now he doesn't want to say more, he talks too much, and he will always show his feet.

"Lao Qin, Mr. Yun, the contract is ready, you can take a look at ...... first" It happened that at this time, Zhao Hui came in with a few printed contracts.

The contract is very simple, that is, it is written that Yunfei will exchange LSK9201 for 40% of the shares of Huadu CNC Equipment Co., Ltd. and 12 million in cash. Yunfei does not interfere in the daily operation of the company, only acts as a technical consultant and waits for year-end dividends......

Qin Qingshan took the contract, read it, and then handed the contract to Zeng Hongqi and Liang Qiang next to him. Yun Fei carefully read the contract word by word, and found that the contract was written in great detail, although it could not be compared with the commercial contract samples he saw on the Internet in later generations. This contract, which is only three pages, is clear and clear about the responsibilities and obligations of both parties, so he picked up the fountain pen handed over by Zhao Hui and signed his name under the gaze of several people.

Yun Fei left. Left a thick stack of drawings, took away two million cash checks from ICBC, and 40% of Huadu CNC's equity. The remaining 10 million in cash, the contract clearly stipulates. Yunfei must assist Huadu CNC to produce this system completely, and produce LSK9201 samples, which can achieve more than 70% of the functions of the drawing design, and the equity transfer contract will take effect. At the same time, he paid Yun Fei the remaining 10 million in cash.

In other words, what Yun Fei gets now is equivalent to a deposit.

Yun Fei didn't care much about this. After all. The drawings have been indicated on how to choose the various hardware of this CNC system, if it takes a few months to get it done, Yun Fei will have a headache about whether he has chosen the wrong partner.

This world is no longer his original world, and the number of flowers is not the number of flowers that the original world and foreigners stand together, even if there is a problem, the number of flowers can not produce the simplest lathe control system in a short time, and Yun Fei can only consider himself unlucky.

Who told him to measure the world he is in now from the perspective of his own world!

Yun Fei rejected the suggestion that several shareholders should stay and have dinner together to celebrate. He now needs to go to Jimin Hospital to see his uncle, and then there is Hui Xin Kaixing, it is estimated that at this time, Ren Zhiguo is teasing his secretary while scolding himself and Wang Qingfeng.

After Qin Qingshan and the others left Yun Fei, they began to study the drawings left by Yun Fei in detail. They had to study the drawings thoroughly in the shortest possible time, produce a sample, and after the tests were complete, bring the system to market.

After all, now several of them are carrying a loan of 12 million from the Industrial and Commercial Bank of China, especially Qin Qingshan, according to his share of the original shares, one person accounts for nearly 9 million loans, if he can't put this system on the market in time, the annual interest of 10 percent is enough to give him a headache. If he was riddled with debt, he wouldn't expect to come up with a CNC system again.

Now at the beginning of April, Qin Qingshan and several people discussed that they must complete the various tests of the LSK9201 before September, and then they can seize the opportunity to appear at the Huadu Trade Fair, which may save a lot of promotion costs.

Of course, Yun Fei just suggested that the first set of C series systems for lathes should be made out first according to the drawings, so as to facilitate the return of funds. Qin Qingshan and several people want to get the C series lathe system and the X series milling machine system all at once. After all, they have also produced nearly 100 sets of CNC systems, and the assembly system of Zhiludao is very simple, and the only complicated thing is that the setting of various functional parameters and the PLC ladder logic control program for various controls are input into it.

The C series lathe system cloud has left the PLC ladder program, and the X series milling machine system ladder program is not difficult to do, after all, it is too long, far from the ladder program that he compiled Wang Qingfeng's simple system of second-hand milling machine as easy.

If Yun Fei had a four-axis machining center without a ladder program in front of him, Yun Fei could only stare dryly. (To be continued......)
