Xie Zhenhua's expression was not good.

As soon as he came in, he first sighed softly, and then said in a low tone: "Mr. Chang, we are going to be disappointed, the people from Siemens have made it clear that the control system of the DJ4 electric locomotive is one of the core technologies, and they do not sell it." ”

What the!

Don't sell!

Chang Jinlin's expression became solemn all of a sudden, if people don't sell it, it will be troublesome. The control system can not be completely localized, how to achieve the localization rate of DJ4 electric locomotive to reach the goal of more than 80.

Big problem.

Chang Jinlin said slowly: "Old Xie, you didn't say that we could pay a high price. ”

Xie Zhenhua said: "I said, but people say that no matter how much money is sold, the whole set of control system technology is not sold, and no matter how much money is sold." ”

For electric locomotives, the control system is very critical and belongs to one of the core technologies, and it is normal not to sell it. Since Siemens refused so much, no matter how much money it had, it would not sell it, then the road was basically blocked.

Chang Jinlin muttered: "Lao Xie, it seems that it is better to ask for others than to seek yourself, or we have to rely on ourselves, now in this situation, we have only one way to go, that is, to concentrate technical strength and make every effort to develop our own control system." ”

Xie Zhenhua also agreed: "That's the only way, we try our best, but we have to develop the control system before the mass production of the DJ4 electric locomotive, which is too difficult." ”

Chang Jinlin said: "I will go to the capital again to run, make full use of resources, strive for some special scientific research funds, and then try to persuade some experts to join our scientific research team." ”

That's it, that's all it can be.

The Red Star Factory is ready to try it out and strive to develop the DJ4 control system. It's just that whether it is Chang Jinlin or Xie Zhenhua, to be honest, there is not much bottom.

………

Tang flew back to his company.

When he was in Chen Guihong's office, in the face of Chen Guihong's inquiry, Tang Fei didn't say anything to death, but just promised to give it a try.

Because Tang Fei knew that the control system of the DJ4 electric locomotive was extremely high-tech, which was not trivial, so he deliberately said so. In fact, Tang Fei is still somewhat sure that he can successfully develop the control system, because he not only has the system in his hand, but also has a lot of technology about DJ4 electric locomotives, including some core technologies.

Back in his office, sitting in the comfortable boss's chair, Tang Fei thought to himself, Hongxing Factory wants to improve the localization of DJ4 electric locomotives, which is really a good thing, and will purchase a large number of its own accessories.

Such as terminals, interior boards, almost all types of motors required on DJ4 electric locomotives, as well as control cabinets, traction motor systems and so on.

In this way, if the DJ4 electric locomotive is mass-produced, the accessories provided by each car will account for a large proportion, and it is estimated that three or five million per car is not a problem, or even higher.

Each car is three or five million, and what about ten cars, a hundred cars. As soon as he calculated this, Tang Fei himself laughed.

Well, there's also the control system for the DJ4 electric locomotive, which I had to develop. Such core technology cannot be controlled by others, but must be in our own hands.

After thinking about it, Tang Fei organized a meeting and talked about the Red Star Factory's improvement of the localization rate of DJ4 electric locomotives.

Hearing this, everyone seemed very happy, and Liu Jiang said loudly: "Boss, this is a great thing for us, which means that Hongxing Factory will purchase a large number of our accessories, and we can make a lot of money with this piece alone." ”

Tang Fei said: "Yes, this is a good thing, Uncle Liu, your production task is heavier, and you must complete the accessories required by the Red Star Factory with quality and quantity." ”

Liu Jiang almost patted his chest and said: "There is no problem with this, leave the production matter to me." ”

Tang Fei glanced at Liu Jiang approvingly. I thought in my heart, although Liu Jiang is a little older and only has a high degree of Chinese, he has a strong sense of responsibility, and since he was in charge of the production of Jiuzhou Industrial Co., Ltd., he is full of energy and is a good person.

After glancing at Liu Jiang approvingly, Tang Fei said to Wang Hailong: "Hailong, you go to the Red Star Factory and sign the contract with General Manager Chen Guihong for the spare parts of the DJ4 electric locomotive." ”

"Boss, no problem, I'll go to the Red Star Factory to find General Manager Chen Guihong in a minute. Wang Hailong replied.

At this meeting, Tang Fei not only talked about improving the localization rate of DJ4 electric locomotives, but also arranged and divided the relevant work. Such as the signing of the order contract, such as production preparation, etc.

After saying this, Tang Fei said: "At present, the Red Star Plant is facing a big problem, the indicator given above is that when the DJ4 electric locomotive is mass-produced, the localization rate is not less than 80, but this is very difficult. ”

"The key is that some of the core technologies of the Red Star Factory have not mastered, can not form their own design drawings, or can only be imported originally, of which the localization of the control system is the most difficult. ”

Zhao Kedao: "The control system of DJ4 electric locomotive is SIBAS32, microcomputer control, TCN network communication technology, using distributed control, which is completely different from the control system of Shaoshan electric locomotive, and the technical content is much higher, which is indeed very difficult for Hongxing Factory." ”

is worthy of engaging in technology, Zhao Ke suddenly got to the point.

The control system of DJ4 electric locomotive adopts distributed control, while the Shaoshan series electric locomotive adopts the control mode of electronic control cabinet.

There is a big difference between the two, the control system of DJ4 electric locomotive is not only the control cabinet, it also has microcomputer, TCN network communication and so on.

Tang Fei said: "The Red Star Factory once asked me if our Jiuzhou Industrial Co., Ltd. could develop the control system of the DJ4 electric locomotive, and I said that it would be a try, and the Red Star Factory should not have too much hope in this regard." ”

Everyone looked at Tang Fei. Many people know that the boss just said to give it a try, but in fact, he should have made a decision in his heart, that is, to develop the control system of the DJ4 electric locomotive.

Sure enough, Tang Fei said loudly: "Although I said that I would give it a try, I have already decided that the control system of the DJ4 electric locomotive will be contracted by us, and we must take him." ”

Zhao Ke immediately said: "We have successfully developed and produced the control cabinet of the DJ4 electric locomotive, and we will go one step further and develop the entire control system, I think we are still very sure." ”

Tang Fei said: "Yes, let's give it a try, Zhao Ke, you set up a R&D technical team and wait for my instructions." ”

"Okay, boss. ”

Tang Fei did not say that he would set up a R&D technical team and immediately start the R&D work of the control system, but said that there was a reason for waiting for his instructions.

Tang Fei worked in the Red Star Factory for ten years, from an ordinary technician to the deputy director of the technical department. At that time, it was the process of trial production of DJ4, to localization, and then to the development of harmonious electric locomotives, and it was also the golden decade of the development of Huaxia electric locomotive technology.

Tang Fei has a lot of technical knowledge about electric locomotives in his mind, not only the DJ4 electric locomotive, but also many core technologies of the harmonious electric locomotive.

Tang Fei can spend a certain amount of gold to use the research and development function of the system to develop the control system of the DJ4 electric locomotive, or he can rely on the technical knowledge in his mind to build the design framework of the control system.

Zhao Ke set up a technical research and development team, based on the design framework built by himself, and should be able to develop the control system of the DJ4 electric locomotive.

As for the gold coins in the system, Tang Fei wanted to keep them for the time being for the upgrade of the system. At present, there are 3,900 gold coins, which is not far from the 5,000 gold coins needed for the upgrade, and after completing a task released by the system, there should be enough gold coins to upgrade.

After this meeting, Tang Fei returned to his office, turned on his computer, and prepared to build the design framework of the control system according to the knowledge in his mind.

"Ding!"

In my head, this familiar voice sounded again. Don't think about it, it must be that the system is releasing a new task, and suddenly, Tang Fei was overjoyed, and immediately opened the taskbar of the system and saw this new task.

Task content: Ask the host to develop a DJ4 electric locomotive control system for the Red Star Plant.

Mission requirements: six months, no use of the system's R&D function.

Mission Level: Grade D.

Reward: 1800 gold.

Task Punishment: If the task fails, 3000 gold will be deducted.

After reading this newly released system task, Tang Fei thought in his heart, six months is a little urgent, but with his own design and development framework, it should be enough to grasp a little.

The task reward is not bad.,There are 1800 gold coins.,After the task is completed,,The system has enough gold coins to upgrade.,I don't know what the upgraded system looks like.,I'm really looking forward to it!

For the next few days, Tang Fei spent most of his time in his office, immersed himself in "designing and developing" the control system of the DJ4 electric locomotive.

With a lot of technical knowledge about the DJ4 electric locomotive in his mind, Tang Fei felt that it was not too difficult to build the design framework.

After a few days of hard work, the harvest is not small, and the framework has been built halfway through. The design plan has been decided, many design sketches have also been drawn, and some core technical problems have been explained or broken by Tang Fei in the design materials.

Sometimes, the key core technology is separated by a layer of paper, and others have not broken it, you think it is difficult, but once it is broken, you will find that it is the same thing.

Tang Fei not only broke down, but also listed the specific design ideas, listed the design parameters, and tried to be as detailed as possible in the key technical issues.

Today, Tang Fei is also "working hard" in his office as usual, preparing to spend a few more days to make the entire design scheme of the DJ4 electric locomotive, and the design framework is all built, so that Zhao Ke and they can carry out specific design and development work on this basis.

"Knock, knock, knock!"

There was a knock on the door of the office, Tang Fei stopped his design and development work, shook his head and said, "Come in, the door is not locked." ”

Unexpectedly, it was neither Wang Hailong nor Zhao Ke who pushed the door in, but Xie Zhenhua from the Red Star Factory.

Tang Fei got up and said enthusiastically: "Oh, Chief Engineer Xie, you are here in person, what a rare guest!"

……….

Today's three watches, the third watch is complete!
