Meng Xianda came to Su Liangyu to develop a new signal machine.

The train sandbox made during the Lantern Festival in the Science and Technology Park is just a fresh and lively for ordinary people. For professionals like Meng Xianda, they can see many tricks. Although the Ministry of Railways is calling for technological updates and technological reforms, it is just a shout. From the promotion of the first computer interlocking system in the factory and mine railway test in 1984, five years have passed, and the entire system is still under debugging and is still not mature, reaching the level of being able to be used on regular railway lines.

Therefore, Meng Xianda's eyes lit up after seeing the sand table model of the Science and Technology Park. Although the model system is relatively simple than the real railway operating environment, the principled things are not bad at all. At least it is much stronger than the system that the Ministry of Railways made in Meishan Iron Mine in 1984. The computer interlocking system of Meishan Iron Mine is only to solve the problems of stopping, shunting, and marshalling of trains in the station station, and is of little significance to long-distance operations of trains.

Since the 16th lunar calendar, Meng Xianda has been traveling to the Science and Technology Park every day and chasing Su Liangyu about the cooperation in developing new signal machines. However, Su Liangyu is very dissatisfied with Meng Xianda's proposed that the chip laboratory first develops a processor for signal machines and electric switch machines, and then builds a ground control center model.

According to Su Liangyu and Liang Yuan's plan, the entire development plan is centered on the train control system, with the signal machine on the ground and the electric switch machine as auxiliary, which is exactly contrary to the requirements of the Road Bureau Signal Factory. The Road Bureau Signal Factory intends to build a system mainly ground control, and the signal basis for railway driving is mainly based on the rail side signals observed by the driver. However, Liang Yuan intends to make the general head signal commonly used in the future. After the system is improved, the rail side signal can only be in a subordinate position. Even after the main signal of the locomotive is mature in the future, the rail side signal will be eliminated and only an electronic transponder is used to divide the driving section.

After Su Liangyu knew Liang Yuan’s sinister thoughts, he could not let the Road Bureau Signal Factory lead the entire development plan. Therefore, he could only drag it before Liang Yuan came up with the theory of the system.

Meng Xianda took the document handed over by Su Liangyu and started reading it attentively.

In less than three minutes, Meng Xianda slapped the handrail of the sofa "bang", then looked at Liang Yuan and Su Liangyu's surprised eyes and said embarrassedly: "I'm so embarrassed. This document has been written to me. I used to have some vague understanding of the signal system at work, and there is a clear description of this document. I took a photo of the sofa as soon as I was excited."
China's Ministry of Railways is very similar to the military system of our great neighbor, the Republic of India. The equipment used by both are diverse and there are many varieties of brands.

The equipment of the Ministry of Railways comes from many countries such as the United States, Japan, Britain, France, Germany, Jiangsu, Italy, etc. It is a very amazing miracle from an engineering perspective, and of course the potentially dangerous roots were planted at the same time.

Although China's railway equipment in the 1980s had not reached the level of the 1980s as many as Liang Yuan's previous life, the United States, Japan, the Soviet Union and France had already occupied their respective territories on the territory of China's railways, but it was due to political and economic restrictions and did not expand greatly.

At this time, the conflicts in railway equipment standards in various countries were already vaguely visible. Therefore, Meng Xianda was very excited after seeing Liang Yuan's pirated ltcs system.

"To be honest, this development plan... can no longer be called a development plan. Who made the plan for this railway operation system? Can Gong Su recommend it to me?" Meng Xianda, who had read the entire material, said excitedly.

Su Liangyu looked at Liang Yuan and signaled that he should answer this question.

"Uh..., this plan is... it was done by a friend of my uncle in the United States. He was doing research on railway signal systems at Bell Laboratory in the United States." Liang Yuan directly pulled Jian Zhikang's background over to make a cushion.

When Meng Xianda heard that the author was in the United States, he sighed with disappointment and said, "It's a pity that you can't ask in person. I really didn't expect that if you are so far away from our country, you can still make such a plan that suits our country's railway operation. The United States' technology is indeed developed, which makes people admire it."

Listening to Meng Xianda's feelings, Su Liangyu didn't know what to say. Su Liangyu knew that this set of documents was made by Liang Yuan. After looking at Liang Yuan who pretended not to know anything, the two looked at each other speechlessly.

"This is..." Meng Xianda, who expressed his sigh, wanted to ask who Liang Yuan was.

"Oh, my uncle Liang Haiping works for the Northeast Locomotive Factory. I am his nephew, just call me Xiaoyuan."

Liang Haiping's name is very famous in the Road Bureau now, and at least on the ground in Shengjing, it is definitely well-known.

"Oh, oh, it turns out that you are Haiping's nephew. A few days ago, I saw your uncle come to the road bureau to handle the handling of the Model 25 undercarriage." Meng Xianda said with a smile.

Liang Yuan just smiled after hearing Meng Xianda say it.

"Xiaoyuan, is there any subsequent part of this plan?" Meng Xianda asked.
"No more, my uncle gave so much." Liang Yuan shook his head and said.

"What a pity, I still have not finished my wish," Meng Xianda said smacking his lips.

Meng Xianda gently touched the entire document with his hand, and after a while, he said embarrassedly: "Xiaoyuan. Can I copy this plan?"

"Yes, my uncle said that the author who wrote the plan did not have a plan to return to China to work. Writing this thing was just doing his best to the development of the national railway. Domestic units or individuals reprinted and excerpted it casually." Liang Yuan directly solved the problems that Meng Xianda was concerned about in his subconscious mind.

"Oh, so that's it." Meng Xianda pondered for a moment before continuing: "Su Gong, Xiao Yuan, I'm willing to take this plan as the main body. To supplement the practical problems I experienced in my daily work, submit them to the People's Railway Newspaper, can Xiao Yuan tell me the name of the author who made this plan? Fortunately, the article was signed."

Liang Yuan grabbed his hair and said, "I don't know what the author is, I have to ask my uncle."

Su Liangyu smiled and said, "Meng Gong, don't ask me about this matter. This plan does not belong to the chip laboratory, and I have no objection."
"Okay, this plan is much more reasonable and perfect than the one produced by our factory. After I go back, I will show the plan to Director Pan. I guess Director Pan should agree with the viewpoint of this plan. Then I will implement it step by step according to the plan in the document."

More than ten minutes later, Meng Xianda left Nanhu Science and Technology Park with the copied documents with satisfaction.

Watching Meng Xianda walk out of the office building and turn into the park corridor of the Science and Technology Park, Su Liangyu withdrew his gaze and looked at Liang Yuan who was leaning on the sofa and drinking coffee, saying, "Xiaoyuan. If you don't call Haiping, you will be exposed."

Liang Yuan raised his hand and looked at his watch and said, "Wait for a few more minutes. Whether my uncle is in Shengjing or Benxi, he must be holding a quality meeting. He called 97 and went to the office, but no one answered it."
"There are no secrets, Lao Su had known it for a long time. I didn't mention it to you a few days ago. With the advancement of chip technology, the railside signals of the railway system will be destined to disappear in large quantities in the future. How could I write such a thing in front of the signal factory?"

"There is no one who blatantly lets others dig their own graves?" Liang Yuan said with a smile.

ltcs3 is a train operation control system based on wireless transmission of information and uses rail circuits to check trains occupied by trains. It is generally used for speeding up trunk lines or new high-speed railways. Wireless communication is used to form blocked areas or rely on trains. The control center on the ground implements virtual automatic closure. After the railway driving system completes this level of transformation, the ground can be not equipped with a signal machine, and the locomotive crew drives with on-board signals.

Liang Yuan explained the equipment structure, operation ideas and planning of ltcs3 with Su Liangyu, and then said: "Take domestic railways as an example, once the upgrade and transformation of the ltcs3 system is completed, more than 100,000 domestic railway equipment will basically be eliminated. In the future, the rail-side signal machines will only survive within the station and remote lines. The entire signal market will shrink by at least two-thirds. How dare I put this tragic ending directly in front of the manufacturer that produces signal machines."

"If we scare people away, where are we going to find such a good cover and squeeze into the production circle of railway signal equipment? Didn't we even give up the copyright of the ltcs system?" Liang Yuan said proudly.

"You have given up, but you obviously want to rob and still want a good reputation." Su Liangyu said with a smile.

Now that Su Liangyu and Liang Yuan have been staying for a long time, Liang Yuan often guesses a lot of things. Companies that can produce signal machines and rail-side equipment must be state-owned enterprises in the Ministry of Railways. With the upgrade of the ltcs system, they will definitely kick everyone's meal pot in the future. Liang Yuan will never take action on such a large number of things that attract hatred. When the ltcs promotion plan cannot be delayed, it is very necessary for the "big-head" company that attracts hatred to come out.

Note 1: The skeleton of our railway was completely imitated by the Soviet Union, and this mark was almost completely erased after the new century.

Note 2: The special classification method of the railway industry is like the railway industry calling the number "0" and the number "7" is called the crawl.

I'm much better and I'll recover for 2 more tomorrow.

The fastest update, please.
