Intelligent Industrial Empire

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

At the urging of the two, Yun Fei went to his car and took the drawing 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 soon.In an attitude of being responsible for himself, Yun Fei gave an extremely detailed explanation to several people this time.The various functions of this system were explained separately to several people. After Zhao Hui got the contract, he only explained the structure of the PLC programmable controller of this numerical control system.He still didn't show the drawings of the MCU.

For this system, 8-bit microcontrollers based on Intel’s 51 series core produced by many companies in Taiwan are fully competent.Taiwan has built a lot of factories on the mainland in recent years, and they do not have the technology blockade of China like Europe, America 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 control only high-end products such as 16 bits. The control of the eight-bit 8051 is not too strict. There will be as many four-bit 8031 ​​as there are now. How much. However, in the key parts of this system, the 8031 ​​control capability is not enough. At least 8051 or the same grade single-chip microcomputer is needed." When Yun Fei talked about the control structure of the CNC system he copied, Qin Qingshan asked worriedly what model of MCU to choose.

Yunfei originally copied some of the single-chip microcomputers of later generations, except for a set of the most practical control chip design drawings.But at this time he was even more afraid to take out his own set of chip designs.

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

Several old men engaged in numerical control research, which makes sense. After all, China has successfully developed numerical control machine tools in the late 1950s.If those old men are engaged in CNC machine tools or CNC systems, they still have the energy and conditions to engage in computer hardware, he doesn't believe it.If the old men really have this ability, after the great turmoil is over, they will surely be recruited by the country as soon as possible.

Computers, in the late 70s and early 80s, there were few talents.

"Single-chip computers have two structures on the market now. They are the centralized instruction CISC and the reduced instruction RISC. The CISC structure is also called the von Norman structure. The data line and the instruction line are time-division multiplexed, and the instructions are rich and powerful, but It is precisely because of its structure that fetching instructions and fetching data cannot be performed at the same time. The use of a single-chip microcomputer with this structure as the industrial control chip of the numerical control system will limit the control speed. Moreover, the single-chip with this structure has a maximum Disadvantages of the machine-the price is too high. Anything that is better can cost several dollars or even dozens of dollars. Even so, our system has to use a single-chip microcomputer of this structure as the control core, because the CNC machine tool runs during operation. It's very complicated, especially the linkage of several axes at the same time." Yun Fei discovered that these guys who are engaged in CNC systems do not seem to have a good understanding of these most basic things.

How did he know that the domestic CNC system is not a guy from later generations who possesses the ultimate artifact like Du Niang. As long as there is something he doesn’t understand, Du Niang will tell him the countless results. The things I want to connect are displayed.

It was difficult to get an 8031 ​​chip for domestic research in this area before, and there was no way to let all the people doing research understand it in detail.

"..." The few people who seemed to understand, stared at Yun Fei longingly.

"Damn, I was defeated by you... Our system can be used, not only Intel's 8051 series, Taiwan Winbond W78, I think it is more suitable for our system. I won't worry about getting stuck in the future, and the price is relatively high. Inexpensive. Of course, the quality is definitely not comparable to that developed by guys who grew up eating raw beef. But this is still acceptable to our domestic users."

Yun Fei felt that the two lifetimes combined would not be more tiring than explaining these things to a few half-old men now.If it wasn't for the soul to reach this body, it turns out that many things he browsed on the Internet in that world would appear as long as he thought of keywords, and he didn't know what to do.

Just for 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.Numerical control system is just an understanding.It is really difficult to use these knowledgeable things to fool these professional old things.

Qin Qingshan and Liang Qiang's eyes straightened while Zeng Hongqi was lethargic.Yun Fei took out a cigarette and handed it to Zeng Hongqi and Liang Qiang, one for each, and regardless of them, he leaned back on the back of the chair and rested on his own.Yun Fei knew that Qin Qingshan didn't smoke.

"Director Yun, Winbond's chip, we are using it now, can we use this set of machine tools that can control three-axis linkage?" Qin Qingshan digested the things Yunfei just said, and saw that Yunfei was about to sleep. Now, he asked Yun Fei eagerly.The systems they used to assemble have various accessories from all over the world. As long as they can get them, are compatible, and put them together to make the system run, they are very grateful.

Now LSK9201 can no longer mess around like the systems they assembled. If the reputation is smashed, not only the old people who have struggled for this system for 30 years, but also the 40% of the shares they lost. .

It can be said that Yun Fei's system allowed him to see another world, and the things that Yun Fei was talking about now seemed to be the keys to opening the door that he looked at but couldn't touch.

Qin Qingshan never thought about where Yun Fei got this knowledge.He felt that Yun Fei understood these for granted.The other two also didn't feel any surprises either. Originally, Yun Fei was worried that he had said too much and couldn't explain where it came from.After all, these things produced abroad, Yun Fei knows more than the professionals like Qin Qingshan.Now he is reluctant to say too much, he will always show his feet.

"Old Qin, President Yun, the contract is ready, you can take a look first..." At this moment, Zhao Hui came in with a few printed contracts.

The contract is very simple. It states that Yunfei will exchange LSK9201 for 40% of Huadu Numerical Control Equipment Co., Ltd. shares and 12 million in cash.Yunfei does not interfere with the company's daily operations, only as a technical consultant and waiting for year-end dividends...

Qin Qingshan accepted the contract, and after reading it, he handed it to Zeng Hongqi and Liang Qiang next to him. Finally, after the two confirmed that there was no problem, he seriously signed the name of his boss.Yun Fei carefully read the contract verbatim, and found that the contract was written in great detail, although he could not match the sample commercial contract he saw online.This three-page contract is very clear about the responsibilities and obligations of both parties. He raised the pen handed by Zhao Hui and signed his name under the eyes of several people.

Yun Fei left, leaving behind a thick pile of drawings, taking away 2 million cash checks from ICBC and 40% equity of Huadu CNC.For the remaining 10 million in cash, the contract clearly stipulates that Yunfei must assist Huadu CNC to produce this system completely. The LSK9201 sample is produced, which can achieve more than 70% of the functions of the drawing design. The transfer contract will take effect, and Yunfei will spend the remaining 10 million in cash.

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

Yun Fei didn't care much about this.After all, the drawings have 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 to worry about whether he has chosen the wrong partner.

This world is no longer his original world, and the flower count is not the same as that of the original three-legged world with foreigners. Even if there is a problem, the flower count cannot produce the simplest lathe control system in a short time. Admit it to yourself.

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

Yun Fei rejected the idea of ​​spending a few shareholders staying to have dinner together to celebrate.He now needs to go to Jimin Hospital to see his uncle, and then return to Xin Kaixing. It is estimated that at this time Ren Zhiguo is teasing his secretary while yelling at him and Wang Qingfeng.

After Yunfei left, Qin Qingshan began to study in detail the drawings left by Yunfei.They must thoroughly study this set of drawings in the shortest possible time, and then produce samples. After the test is completed, they must put the system on the market.

After all, a few of them now carry a loan of 12 million yuan from ICBC, especially Qin Qingshan. According to his original share of shares, one person accounts for nearly 9 million yuan in loans. The system is listed and marketed, and an annual interest of 10% is enough to give him a headache.If he is bound by debts, he shouldn't expect to come up with a CNC system.

It is now in early April, and several people from Qin Qingshan have discussed that they must complete the various tests of LSK9201 before September. Only then will they be able to seize the opportunity to make an appearance at the Huadu Fair, which may save a lot of promotion costs.

Of course, Yunfei just suggested that the first system of the C series for the lathe should be developed according to the drawings to facilitate the return of funds.All of Qin Qingshan wanted to get the C series lathe system and the X series milling machine system all at once.After all, they have also produced nearly a hundred sets of CNC systems, knowing that the assembly system is very simple, the only complicated thing is to input various function parameters and PLC ladder logic control programs for various controls. .

The C series lathe system Yunfei has left the PLC ladder diagram program, and the X series milling machine system ladder diagram program is very rare. After all, it is too long, far from the trapezoid of the simple system of Wang Qingfeng’s second-hand milling machine he compiled. The diagram procedure is as easy as that.

If Yunfei had a four-axis machining center without a ladder program in front of him, Yunfei would only be stared.
