Meng Xianda came to Su Liangyu for the development of a new type of signal.

Science and Technology Park Lantern Festival to get that set of train sand table, for ordinary people is to see a fresh and lively, for Meng Xianda this kind of professionals, but can see a lot of doorways, don't look at the Ministry of Railways shouting about technological updates, scientific and technological reform, that is, shouting, from 84 years in the factory and mine railway test to promote the first set of computer interlocking system, to now five years have passed, the whole system is still in the process of commissioning, still not mature, to be able to use on the regular railway line Cheng dù.

Although the model system is relatively simple compared to the operating environment of the real railway, the principle is not bad at all, at least it is much stronger than the system made by the Ministry of Railways in Meishan Iron Mine in 84 years. The computer interlocking system of Meishan Iron Mine only solves the problems of train stopping, shunting and marshalling in the station, which is of little significance for the long-distance operation of trains.

Since the sixteenth day of the lunar calendar, Meng Xianda has been running to the Science and Technology Park every day, chasing Su Liangyu to talk about the cooperation in the development of new signals, but Su Liangyu is very dissatisfied with Meng Xianda's proposal that the chip room first develops processors for signals and electric switch machines, and then builds a ground control center.

According to Su Liangyu and Liang Yuan's plan, the whole development plan is based on the train control system as the core, and the signal machine and electric switch machine on the ground are assisted, which is exactly the opposite of the requirements of the Road Bureau Signal Factory. Liang Yuan plans to engage in the general locomotive signal commonly used in the future as the main body, when the system is perfected, the trackside signal can only be in a subordinate position, and even after the main locomotive signal matures in the future, the trackside signal will be eliminated, and only the electronic transponder will be used to divide the driving section.

After Su Liangyu knew Liang Yuan's sinister thoughts, how could he let the Road Bureau Signal Factory lead the entire development plan, so he could only drag it out before Liang Yuan could figure out the theory of the system.

Meng Xianda took the text handed over by Su Liangyu. I watched it intently.

In less than three minutes, Meng Xianda patted the armrest of the sofa, then looked at Liang Yuan and Su Liangyu's surprised eyes, and said with some embarrassment: "I'm really embarrassed." This article is written in my heart, and some vague understanding of the signal system in my previous work is clearly described in this article. As soon as I was excited, I slapped the sofa. ”

CTCS system is at the advent of the new century, China's railway system summed up the experience of China's railway operation for half a century, with the momentum of the system from a high position, although in the practical application of the Wenzhou bullet train rear-end collision such a tragic accident, but the core idea of the construction system itself is not wrong, the fault is only the technical factors.

As far as the CTCS system itself is concerned, it can be called the world's most compatible railway traffic control system, and the architecture of the CTCS system truly reflects the strong strength of the Republic in system integration.

China's Ministry of Railways is very similar to the military system of our great neighbor, the Republic of India, and both use a variety of sources of equipment. There are many varieties and brands.

The equipment of the Ministry of Railways comes from the United States, Japan, Britain, France, Germany, the Soviet Union, Italy and many other countries, and the integration of these different types of railway equipment into a large system is quite a remarkable miracle from an engineering point of view, of course, the bane of potential dangers has also been planted at the same time.

Although the Chinese railway equipment in the 80s has not yet reached the level of the universal equipment in Liang Yuan's previous life. However, the United States, Japan, the Soviet Union (Note 1), and France have already occupied their respective territories on the map of China's railways, but due to political and economic constraints, they have not expanded aggressively.

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

"Truth be told, this development plan ...... , I can't call it a development plan, who made this plan for the railway operation system?Can Su Gong introduce me to it?" Meng Xianda, who had read the entire material, said with a little excitement.

Su Liangyu looked at Liang Yuan and signaled that this question should be answered by him.

"Uh...... , this plan is...... It was done by a friend of my uncle in the United States, who was doing research on railway signaling systems in the Bell Sil room in the United States. Liang Yuan directly pulled Jian Zhikang's background over and made a cushion.

Hearing that the author himself was in the United States, Meng Xianda sighed with some disappointment and said: "It's a pity that I can't ask for advice in person, I really didn't expect that so far away from our country, we can make such a plan that is in line with the operation of our country's railway, and the United States has developed science and technology, which makes people have to admire." ”

Listening to Meng Xianda's emotion, Su Liangyu also didn't know what to say, Su Liangyu knew that this set of texts was made by Liang Yuan, and looked at Liang Yuan, who pretended not to know anything, and the two looked at each other a little speechlessly.

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

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

Liang Haiping's name is now very loud in the road bureau, at least on the ground in Shengjing, it must be called thunderous.

"Oh, oh, it turns out that you are Haiping's nephew, and I saw your uncle come to the Road Bureau to handle the handover of the 25-type car a few days ago. Meng Xianda said with a smile.

Liang Yuan just smiled when he heard Meng Xianda finish speaking.

"Xiaoyuan, is there a follow-up part of this plan?" Meng Xianda asked.

Since it was shown to the Signal Factory of the Road Bureau, Liang Yuan only wrote out the equipment architecture, operation ideas, and planning of the first three levels of the CTCS system, from CTCS0 (Note 2) to CTCS2, and the follow-up ...... But there was not a word.

"No, my uncle gave so much. Liang Yuan shook his head and said.

"It's a pity, it's still unfinished," Meng Xianda smacked his lips and said.

Meng Xianda gently touched the entire text with his hand, and after a while, he said with some embarrassment: "Xiaoyuan." Can I make a copy of this plan? ”

"Yes, my uncle said that the author who wrote the plan has no plan to return to China to work, and he only writes this thing to make some meager contributions to the development of the national railway, and domestic units or individuals can reprint and excerpt it casually. Liang Yuan directly solved the problem that Meng Xianda was concerned about subconsciously.

"Oh, so that's the case" Meng Xianda pondered for a moment before continuing: "Su Gong, Xiaoyuan forgive me for being presumptuous, I plan to take this plan as the main body. After adding some practical problems that I have experienced in my daily work, and posting them to the "People's Railway Daily", Xiaoyuan can tell me the name of the author who made this plan. Fortunately, the article is signed. ”

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

Su Liangyu said with a smile: "Meng Gong, you don't need to ask me about this matter. This plan doesn't belong to the chip room, I don't have any opinion. ”

"Oh, then I'll call Haiping directly. ”

Su Liangyu called the administrative office, asked someone to come over to pick up the document to make a copy, and then said to Meng Xianda: "Meng Gong, you also read the plan just now, how about we make a development plan according to this?"

"Okay, this plan is much more reasonable and perfect than the one made by our factory, I will show the plan to Director Pan when I go back, I guess Director Pan should agree with the view of this plan." It was implemented step by step according to the plan in the text. ”

More than ten minutes later, Meng Xianda left Nanhu Science and Technology Park with the photocopied text.

Watching Meng Xianda walk out of the office building and turn onto the park corridor of the Science and Technology Park, Su Liangyu retracted his gaze, looked at Liang Yuan, who was leaning on the sofa and drinking coffee, and said, "Xiaoyuan." If you don't call Haiping and don't make a good confession, Lao Meng will be exposed as soon as he calls. ”

Liang Yuan raised his hand and looked at his watch and said, "Wait a few more minutes, whether my uncle is in Shengjing or Benxi, he must be holding a quality meeting, and no one will answer the phone when he calls the office." ”

Su Liangyu poured himself a cup of tea. Then he looked at Liang Yuan and smiled and said, "Xiaoyuan, I'm curious, you have hidden the two levels of LTCS3 and LTCS4 in this plan, what secrets are there here." ”

"How can there be so many secrets, Lao Su has known for a long time, didn't I mention to you a few days ago, with the progress of chip technology, the trackside signals of the railway system are destined to disappear in large numbers in the future, how can I write this kind of thing in front of the signal factory." ”

"How can anyone blatantly let people dig their own graves. Liang Yuan said with a smile.

LTCS3 is based on wireless transmission of information and the use of track circuits and other ways to check the train operation control system, generally used in the speed of the trunk line, or the new high-speed railway, the use of wireless communication to form a block section or by the train, the ground control center to implement virtual automatic blocking, the railway system to complete this level of transformation, the ground can not be set up through the signal, the locomotive crew with the on-board signal to drive.

Liang Yuan explained the LTCS3 equipment structure, operation ideas and planning to Su Liangyu, and then said: "Taking the domestic railway as an example, once the upgrade of the LTCS3 system is completed, the more than 100,000 Tongguò signals of the domestic railway equipment will basically be eliminated, and the future trackside signals can only survive in the station and remote lines, and the entire signal market will shrink by at least two-thirds. ”

"In case people are scared away, where are we going to find such a good pretense to squeeze into the circle of railway signaling equipment production, don't you see that I have even given up the copyright of the LTCS system," Liang Yuan said proudly.

"Where did you give up, but you obviously want to rob and have a good reputation. Su Liangyu said with a smile.

Now Su Liangyu and Liang Yuan have been staying for a long time, Liang Yuan's careful thinking often guesses a lot, the enterprises that can produce signals and trackside equipment must be state-owned enterprises in the circle of the Ministry of Railways, with the upgrade of the LTCS system, the future will definitely kick everyone's rice pot overturned, this kind of thing that attracts a lot of hatred, Liang Yuan will never start in person, in the LTCS promotion plan can not be delayed, it is very necessary for the company to cultivate a "big head" that attracts hatred

Note 1: The skeleton of our railways was completely modeled after the Soviet Union, and this imprint was almost completely erased after the new century.

Note 2: The characteristic division of the railway industry is like the railway industry, which calls the number "0" and the number "7" called the turn

The body is much better, and Ming'er is more restored. RS
