Chapter 231 Control Systems
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 have to pay so much attention.As soon as Tang Fei came in, he said loudly: "Brother Chen, what do you want from me?"

After finishing speaking, he sat down on the sofa, took a sip of the hot tea that Chen Guihong had brewed for himself in advance.

Chen Guihong said: "Brother, I really have something to ask you to come here. Our president Chang held a meeting in Beijing a few days ago, and the above asked to increase the localization rate of DJ4 electric locomotives. Our factory held an office meeting yesterday to discuss this matter." matter."

"Oh." Tang Fei looked at Chen Guihong seriously.

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

In my own memory, when the DJ4 electric locomotive was successfully trial-produced and entered mass production for a period of time in history, similar meetings were held at the top to start to improve the localization rate of the DJ4 electric locomotive.

This is much earlier than in history. Could it be that history has quietly changed after I was reborn? Well, that should be the case.

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

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

Chen Guihong said: "Brother, what I want to talk to you about is to increase the localization rate of DJ4 electric locomotives. You are our important suppliers. It was decided at yesterday's office meeting that a large number of spare parts for DJ4 electric locomotives will be required. Nationalization."

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

"As for the required IGBT products, control cabinets, traction motor systems, etc., let alone purchase them from you..."

The meaning of Red Star Factory is obvious. The focus is on Jiuzhou Industrial Co., Ltd. Many parts were originally imported, but now they are purchased from Jiuzhou Industrial Co., Ltd. instead.

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

This is a good thing!
In this way, the localization rate of the DJ4 electric locomotive will be greatly improved, and it will be able to manufacture a large number of spare parts for the DJ4 electric locomotive and earn a lot of profits.

Tang Fei agreed straight away: "Okay, there is no problem at all. I will send someone over to discuss in detail what parts to purchase and what technical requirements there are."

Seeing that Tang Fei agreed immediately, Chen Guihong felt relieved for a while. The task entrusted to him by the leader was finally successfully completed.

By the way, there is one more thing.

Chen Guihong said: "Brother, you developed and manufactured the control cabinet of the DJ4 electric locomotive. Mr. Xie asked me to ask if you can develop the complete control system of the DJ4."

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

It was precisely because of knowing this that Xie Zhenhua didn't ask Tang Fei himself, but asked Chen Guihong to try first.

The entire control system of the DJ4 electric locomotive is not a simple thing.Its technical difficulty is above the traction motor system.

The control system is equivalent to the nerve center of the electric locomotive. Many commands are issued through the control system, which has a high technical content. It is also one of the core systems on the electric locomotive.

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

As for Chen Guihong, he looked at Tang Fei hopefully, waiting for Tang Fei's answer.He knew that if Jiuzhou Industrial Co., Ltd. could develop the vehicle control system, it would definitely be the greatest boon for Hongxing Factory.

After a long time.

Tang Fei said cautiously: "The control system of the DJ4 electric locomotive is very technically difficult. I can only try it. It's good if it succeeds. If it doesn't work, there's nothing I can do about it."

Tang Fei didn't say anything to death.

Chen Guihong also knew that it was very difficult to develop the control system of DJ4. It was completely normal for Tang Fei to say so.It would be abnormal if Tang Fei agreed straight away and said there was no problem at all.

"Brother, then please."

"Well, I'll try my best."

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

.........

in the office.

Chang Jinlin is listening to Xie Zhenhua's report. He held an office meeting yesterday, and everyone formed a unified opinion. The spare parts of the DJ4 electric locomotive can be purchased from China as much as possible. merchants to do it.

This is not enough.

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

In order to achieve a localization rate of more than 80% during mass production, a lot of technologies need to be absorbed and digested. Some Red Star factories have no problems, but some have great difficulties.

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, "Old Xie, what are the difficulties?"

Xie Zhenhua said with a solemn expression: "The control system of the electric locomotive and the variable voltage and flow system are not trivial, and the technical content is extremely high. It is too difficult to overcome them before the DJ4 electric locomotive is mass-produced."

"If these two systems have not been localized, it is almost impossible for the localization rate of the DJ4 electric locomotive to reach more than 80%."

Immediately, Chang Jinlin also felt the pressure.

After a long time, he said slowly: "DJ4's variable pressure and variable flow system is a little bit better, Qingjiang Institute should be able to conquer them."

Qingjiang Electric Locomotive Research Institute, like Hongxing Factory, is also a subsidiary of Huaxia Electric Locomotive Group. The technical advantage of Qingjiang Institute is the transformer of electric locomotives. It has a deep technical accumulation in variable voltage and current systems. , may be able to make a localized variable voltage and current conversion system that can satisfy the DJ4 electric locomotive.

But what about the control system of the DJ4 electric locomotive?
This is the central nervous system of the entire electric locomotive, and many commands are issued, fed back, or transmitted by the control system.

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

This is a big question and a big problem.

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

Chang Jinlin stood up, hands behind his back, frowning slightly, walked up and down in 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., they have successfully developed and produced the control cabinet of the DJ3 electric locomotive." ?"

Xie Zhenhua sighed softly.

"Mr. Chang, a separate control cabinet and the control system of the entire electric locomotive are not the same thing. The latter is much more technically difficult."

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

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

Chang Jinlin said: "Call Xiao Chen now and ask how Tang Fei answered."

Xie Zhenhua picked up the phone and started calling in front of Chang Jinlin. After finishing the call, he sighed softly, "Mr. Chang, I don't have much hope. Tang Fei just said to give it a try, and it seems that there is no hope." Great confidence."

"That's it." Chang Jinlin frowned again, and said slowly: "If the control system of the DJ4 electric locomotive cannot be completely localized, it must reach 80% of the localization rate before mass production. Almost impossible."

After thinking about it, suddenly, Chang Jinlin's eyes lit up, and he thought of a good idea. Immediately, his mood improved a lot, and he thought in his heart, um, 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 give it a try." Chang Jinlin said: "With the cooperation between us and Siemens, the relationship between the two parties is getting better and better. In addition, the benefits of our factory are not bad, and we have some money in hand. Old Xie, please contact Siemens.”

"Try to fight for it. We will pay, even if the price is a little higher, to buy the entire set of technology for the control system of the DJ4 electric locomotive from Siemens."

Paying money to buy technology seems to be a good choice.

Instead of buying the technology of the entire DJ4 electric locomotive, but just buying the technology of the control system, whether it is Chang Jinlin or Xie Zhenhua, they feel that there is still great hope for this, and they can try it.

Xie Zhenhua said: "Mr. Chang, then I'll go and contact the people from Siemens to see if I can buy a complete set of technology for the control system."

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

After watching Xie Zhenhua leave his office, Chang Jinlin took out a cigarette and lit it, thinking while smoking, hoping to succeed.

Whether it will be successful or not is hard to say.

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

Chang Jinlin has not left the office. He has been waiting for news from Xie Zhenhua. When he saw Xie Zhenhua come in, he immediately stood up and was about to ask Xie Zhenhua how the result was. He swallowed abruptly.
