Tang Fei knocked on the door and entered Chen Guihong's office.

The relationship between the two is good, they are buddies, and they don't pay so much attention to it. As soon as Tang Fei came in, he said loudly: "Brother Chen, what are you looking for me?"

After speaking, he sat on the sofa, picked up the hot tea that Chen Guihong had made for himself in advance, and took a sip gently.

Chen Guihong said: "Brother, there is indeed something to come to you, we Chang Zong held a meeting in Beijing a few days ago, and the above requirements were to increase the localization rate of DJ4 electric locomotives, and our factory held a special office meeting yesterday to discuss this matter. ”

"Oh. Tang Fei looked at Chen Guihong seriously.

Chang Jinlin went to Beijing for a meeting a few days ago, Tang Fei knew about it, but he didn't expect it to be a special meeting to improve the localization rate of DJ4.

In my memory, with the successful trial production of the DJ4 electric locomotive in history, it was only after a period of mass production that a similar meeting was held and the localization rate of the DJ4 electric locomotive was started.

This is a lot earlier than history, could it be that after being reborn, history has quietly changed, well, yes, it should be like this.

At least the development of DJ4 has been advanced and the process has accelerated. Now the second DJ4 is about to be dropped. Historically, this has been much slower.

If history has changed, let it change, the general direction will definitely not change, and those big events that should happen will still happen. Tang Fei thought in his heart.

Chen Guihong said: "Brother, what I want to talk to you about is to improve the localization rate of DJ4 electric locomotives, you are our important suppliers, yesterday's office meeting decided, DJ4 electric locomotive spare parts to be localized in large quantities." ”

"Correspondingly, all the copper terminals of the DJ4 electric locomotive are purchased from you, and the interior panels are all purchased from your company, and all the motors, even if they used to use imported motors, are now all purchased from you. ”

"As for the IGBT products that are needed, control cabinets, traction motor systems, etc., not to mention, all of them are purchased from you......"

The meaning of the Red Star Factory is obvious, the focus is inclined to Jiuzhou Industrial Co., Ltd., many parts were originally imported, and now they are purchased from Jiuzhou Industrial Co., Ltd.

Listening to Chen Guihong's procurement plan, Tang Fei was so happy that he almost laughed.

That's a good thing!

In this way, the localization rate of DJ4 electric locomotive will be greatly improved, and I can also manufacture a large number of spare parts for DJ4 electric locomotive and earn a lot of profits.

Tang Fei agreed: "Okay, there is no problem with this, I will send someone over to discuss the specific parts to be purchased and what technical requirements there are." ”

Chen Guihong agreed when he saw Tang Fei, and he was also relieved that the task assigned to him by the leader was finally successfully completed.

By the way, one more thing.

Chen Guihong said: "Brother, the control cabinet of the DJ4 electric locomotive was developed and manufactured by you, and Chief Engineer Xie asked me to ask if you could develop a complete set of control system for the DJ4." ”

A single control cabinet is different from the complete control system of an electric locomotive. The latter is much more technical, complex, etc.

It was precisely because of this that Xie Zhenhua did not ask Tang Fei in person, but asked Chen Guihong to try it first.

The whole control system of the DJ4 electric locomotive is not a simple thing. The technical difficulty lies in the traction motor system.

The control system is equivalent to the nerve center of the electric locomotive, and many instructions are issued through the control system, which is extremely technical, and it is also one of the core systems on the electric locomotive.

Tang Fei thought about it, to do it or not to do it.

Chen Guihong looked at Tang Fei with a hopeful expression, waiting for Tang Fei's answer. He knows that if Jiuzhou Industrial Co., Ltd. can develop the control system of the whole vehicle, it will definitely be the greatest blessing for the Red Star Factory.

After a long time.

Tang Feicai said cautiously: "The DJ4 electric locomotive control system is very difficult technically, I can only give it a try, if it can succeed, if it is not successful, then there is no way." ”

Tang Fei didn't say anything to death.

Chen Guihong also knows that it is very difficult to develop the control system of DJ4, and Tang Fei said that it is completely normal. If Tang Fei agreed, saying that there was no problem at all, then it would be called abnormal.

"Brother, then please. ”

"Well, I'll try my best. ”

The two chatted about the control system, and the topic gradually became wider, and they talked about almost everything.

………

In the office.

Chang Jinlin is listening to Xie Zhenhua's report, yesterday held an office meeting, we formed a unified opinion, DJ4 electric locomotive spare parts can be purchased from the domestic as much as possible from the domestic procurement, can be handed over to the surrounding suppliers to do, try to do it for the suppliers.

This is not enough.

It is necessary to absorb and digest the technology of some key components, develop the design on this basis, form its own technology, and then completely localize.

In order to achieve a localization rate of more than 80 at the time of mass production, there are many technologies that need to be absorbed and digested.

Xie Zhenhua said: "Mr. Chang, we will absorb and digest the core technology of the DJ4 electric locomotive as soon as possible, and promote localization as soon as possible, but ......"

Hearing the word "but", Chang Jinlin immediately asked, "Lao Xie, what are the difficulties?"

Xie Zhenhua said with a solemn expression: "The control system of the electric locomotive, as well as the transformer and current conversion system, are not trivial, and the technical content is extremely high, and it is too difficult to overcome them before the mass production of the DJ4 electric locomotive. ”

"If these two systems are not localized, it is almost impossible for the localization rate of DJ4 electric locomotives to reach more than 80. ”

Suddenly, Chang Jinlin also felt the pressure.

After a long time, he said slowly: "DJ4's transformer system is still slightly better, and Qingjiang Institute should be able to overcome them." ”

Qingjiang Electric Locomotive Research Institute, it is the same as Hongxing Factory, also belongs to the subsidiary of Huaxia Electric Locomotive Group, Qingjiang Institute's technical advantage is the transformer of the electric locomotive, and has a deep technical accumulation of the transformer system.

But what about the control system of the DJ4 electric locomotive?

This is the central nervous system of the entire electric locomotive, and many instructions are sent, feedback, or transmitted by the control system.

Hongxing Factory did not have such technical strength, at least before the mass production of DJ4 electric locomotives, it was completely uncertain to develop a control system that could meet the needs of DJ4 electric locomotives.

It's a big problem, and it's a big problem.

Xie Zhenhua was under a lot of pressure and said with a heavy heart: "Mr. Chang, the control system, it is too difficult, if there is a period of three or five years, there may be some progress, but it is almost impossible to overcome this technical problem before the mass production of the DJ4 electric locomotive." ”

Chang Jinlin stood up, his hands behind his back, his brows furrowed slightly, and walked around his office, thinking back and forth while walking back and forth.

After two or three minutes, he stopped and asked hopefully: "We can't, what about Jiuzhou Industrial Co., Ltd., didn't they successfully develop and produce the control cabinet of the DJ4 electric locomotive?"

Xie Zhenhua sighed softly.

"Chang Zong, a single control cabinet, and the control system of the entire electric locomotive, it is not a thing, the latter is much more technically difficult. ”

"I personally believe that it is very difficult and almost impossible for Jiuzhou Industrial Co., Ltd. to develop the control system of DJ4 electric locomotive in a short period of time. ”

"However, I still asked Chen Guihong to ask Tang Fei's tone, but we shouldn't have too much hope. ”

Chang Jinlin said: "Now call and ask Xiao Chen, how Tang Fei answered." ”

Xie Zhenhua picked up the phone and fought in front of Chang Jinlin, and after the call, he sighed softly, "Mr. Chang, there is not much hope, Tang Fei just said to give it a try, and it seems that he is not very sure." ”

"That's right. Chang Jinlin's brows furrowed again, and he said slowly: "If the control system of the DJ4 electric locomotive cannot be completely localized, it is almost impossible to reach a localization rate of 80 before mass production." ”

After thinking about it, suddenly, Chang Jinlin's eyes lit up, and he thought of a good idea, and suddenly, he was in a much better mood, and thought to himself, Well, maybe this is okay.

Noticing the change in Chang Jinlin's face, Xie Zhenhua immediately asked, "Mr. Chang, have you thought of a solution?"

"Well, we can go and give it a try. Chang Jinlin said: "With the cooperation between us and Siemens, the relationship between the two sides is getting better and better, and the benefits of our factory are not bad, we have some money in hand, Lao Xie, you and Siemens to contact us." ”

"Try to get it, we can pay for it, even if the cost is a little bigger, to buy the whole set of technology for the control system of the DJ4 electric locomotive from Siemens. ”

It seems that paying for technology is also a good choice.

It's not the technology to buy the entire DJ4 electric locomotive, but just to buy the technology of the control system, whether it's Chang Jinlin or Xie Zhenhua, I think this hope should still be very big, you can give it a try.

Xie Zhenhua said: "Mr. Chang, then I will contact the people of Siemens to try to see if I can buy the whole set of technology for the control system." ”

"Well, go ahead, I'll wait for your good news. ”

After seeing Xie Zhenhua out of his office, Chang Jinlin took out a cigarette and lit it, and while smoking, he thought that he hoped to succeed.

Whether it will succeed or not, it's really hard to say.

Xie Zhenhua was very efficient, and in less than an hour, he came back and knocked on the door and entered Chang Jinlin's office.

Chang Jinlin has not left the office, he has been waiting for Xie Zhenhua's news, seeing Xie Zhenhua come in, he immediately stood up at once, and was about to ask Xie Zhenhua what the result was, but he noticed Xie Zhenhua's expression, and swallowed back the words that came to his mouth.
