"Xiaoyuan, things are not as beautiful as you thought. At first, I thought the signal factory of the Road Bureau had a broad vision and a beautiful mind." [][ [First release]" Su Liangyu said with a smile.

"I later found out that the signal factory of the Road Bureau was forced. Although it was not yet at the end of the day, it was almost the same. It was more likely that the mouse would be killed by a blind cat."

"Old Su, can't you make me very happy?" Liang Yuan leaned on the sofa and said weakly.

"Haha, aren't you afraid of misleading your judgment?"

"We only found out the details of the matter later." Su Liangyu picked up the teacup and took a sip before continuing. "The products of the Road Bureau Signal Factory are always suppressed by the Shengjing Signal Factory directly under the Ministry. The product cost is higher than that of the Shengjing Signal Factory, and the quality and stability of the products are not as good as those of the Shengjing Signal Factory."

"It turns out that when the unified procurement plan is allocated, the Road Bureau is still very careful. Everything that the Road Bureau signal factory can do is purchased at home. Anyway, cost accounting is also a matter of the Ministry and has little to do with the Road Bureau. However, after the implementation of the contract, the Ministry will delegate the independent rights and cost accounting at the same time. When purchasing, the Road Bureau will not consider costs but only affiliation. "

"Last year, Shengjing Signal Factory, directly under the Ministry, obtained a 3 million sub-project loan from the World Bank through the Ministry. It introduced a new combination signal machine (Note 1) from Italy to replace the original lens signal machine, and also introduced a new switch voltage monitoring system to transform the domestic zd6 series electric switch machine (Note 2) to greatly improve the reliability of the switch machine."

"It turns out that the signal factory of the road bureau was supported by the road bureau. He did not take the technical transformation of the Shengjing Signal Factory seriously. As a result, after the contract was completed, all sub-departments of the road bureau had to conduct ** accounting. The department that could not support itself would make decisive adjustments, either to switch production or split. The road bureau's electric service section of the road bureau has already made a statement. In order to control costs next year, we will definitely choose the new signal machine and electric switch machine of the Shengjing Signal Factory."

"The result..." Su Liangyu smiled and didn't say anything.

"As a result, the signal factory of the Road Bureau regarded us as a life-saving straw and independently developed the railway computer interlocking system. What a big guise, it sounds very advanced and exciting." Liang Yuan continued.

"You can't say it's not." Su Liangyu smiled strangely.

"The laboratory knows nothing about the system engineering of railway signals. After the Road Bureau Signal Factory made a request for cooperation, we were all a little confused. The signal factory said that chips are of wide use in electrification transformation and are also cutting-edge technology in the international field. With the information given to us by the signal factory, we transferred more than a dozen people. We stayed in the provincial library for four or five days before we got a clue." Su Liangyu said.

"The electrification transformation that is being promoted by the railway system now uses the internationally mature automatic signal machine as instructions, the DC electric switch machine as control, and a large number of relays are the logic core. The 6502 electrical centralized railway interlocking system is composed. The Road Bureau Signal Factory cooperates with us to shout the slogan to develop an internationally advanced railway computer interlocking control system." Su Liangyu said with a smile.

"It's an internationally advanced level, this cow is about to fly to outer space. Lao Su, our laboratory is under a lot of pressure." Liang Yuan said sarcastically.

Looking at Su Liangyu's confusion expression, Liang Yuan grabbed his hair and smiled embarrassedly and said, "Old Su, I'm not talking about ourselves, I'm talking about the signal factory of the Road Bureau. Before the eight characters have been turned, the slogan satellite will go to the sky first."

Liang Yuan mocked the signal factory of the Road Bureau. It was purely the high-profile slogans of the Ministry of Railways in the past life, so that the reflection arc of intuition was formed subconsciously. For example, the 25T passenger bus that the Ministry of Railways hyped in the late 1990s was clearly the BSP high-speed car designed by Bombardier, Canada for Belgium Railway. After the Ministry of Railways introduced it, it changed the electric folding sliding door to an electrical sled door, and added a funny partition in the center of the car, and became a domestically developed quasi-high-speed car under (Note 4). Countless technical "experts" solved their professional titles and solved the funds here. Any normal person, as long as he was a little shameful, would naturally be disgusted with such shameless behavior.-oshuoyd First launch-

Su Liangyu smiled and said, "It's not easy for the Road Bureau's signal factory, Xiaoyuan needs to understand more."

Being able to put down your superior airs, the head of the company takes the initiative to come to the door to fight for the opportunity to save the company. It is also a small outlier among state-owned enterprises in the 1980s, and it should have a rescue value.

Liang Yuan threw the emotions that originated from his previous life aside and asked, "Old Su, have you done a technical evaluation?"

Liang Yuan patted the thick report in his hand and said, "Most of the space here is about how advanced the computer interlocking system is, and it has no technical reference value."

"We did a brief simulation. If we want to build a computer interlocking system on the whole road, the chips required for a single railway signal and electric switch machine will exceed 10 million pieces. If we add the bottom, nose, operation, electric services and other departments, I can't tell how big the market will be."

"But from a technical perspective, the system required by the railway is not difficult. Except for a small number of high-performance processors used for data aggregation, we cannot solve the remaining 99%, which can be solved by chip laboratories nowadays. The problem lies in the integration and debugging of the entire system. Even if a demonstration line is built, the entire system also contains tens of thousands or even millions of chips, ensuring that these chips do not have conflicts in a network, and running safely and stably is the most difficult."

"The train sand table yesterday was only organized in four columns. When we were debugging the system last night, nearly a hundred bugs were found."

Liang Yuan rolled the information in his hand into a volume, gently tapped the handrail of the sofa, thought for a moment, and said with a smile: "I almost got deceived by Lao Su. Lao Su, just say that this job is actually a cool job, and the pure technical difficulty is not very high, mainly because of the manpower."

Su Liangyu laughed and said, "I won't tell you, Xiaoyuan also guessed it."

"If this project is planned to continue, the next step should be to recruit a large number of computer migrant workers." Liang Yuan said with a smile.

"Computer migrant worker?" Su Liangyu repeated in confusion.

Liang Yuan patted his head and remembered that it would take at least 15 years for migrant workers and coders to take the stage of history. Now there are very few people who can do this industry, and they are strongly high-tech talents.

"Computer migrant worker." Liang Yuan explained.

"Haha, Xiaoyuan's metaphor is very appropriate. The project requires not much creative thinking, and the nature of the work is very similar to the step-by-step construction workers."

"Old Su, tell me, how many people and how much money this project requires, I accept my fate." Liang Yuan said with a smile.

"Xiaoyuan, do you really want to do it?" Su Liangyu asked repeatedly.

"Well, my uncle should tell you too. The Northeast Locomotive Factory plans to produce gas turbine locomotives. This project is rare in the world. We have no foreign roads to learn from."

"And even if the gas turbine locomotive is successfully developed, in addition to being used in the legendary Qinghai-Tibet Railway, it is much worse than the diesel head when used in plains. It takes at least five to eight years to improve the fuel economy of the gas turbine locomotives from a technical perspective. There are too many variables for such a long time, and the gas turbine head is easily marginalized. Once it is marginalized, even if technological breakthroughs are made in the later stage, it cannot break the existing pattern."

After hearing Liang Yuan's words, Su Liangyu pondered for a moment and said, "Xiaoyuan, are you planning to rigidly bind the gas turbine locomotive into the entire system by developing a new generation of railway signal control system, right? As long as we complete the computer interlocking system in some areas and form an interaction with the train, the head of the machine will form a contact with the head of the machine, even if the Ministry of Railways wants to promote the electric head of the machine in the future, it will also consider the compatibility of the entire system."

Liang Yuan gently patted the armrest of the sofa and said, "Old Su, you are not lazy either. You are basically close to the level of genius."

"The more popular we promote the new signal system, the greater the advantage. No matter which country's nose comes in, as long as we want to join the signal network of the Ministry of Railways, we must first pass our level. At that time, we just sneeze, and the compatibility of the system alone can make it difficult for a year or two. As long as the situation remains in stalemate for five or six years, it will be a good time to catch up with the troubled waters after we have technically handled the gas turbine motorcycle."

Su Liangyu looked at Liang Yuan and waved his hand excitedly, shook his head speechlessly, but he was extremely puzzled. He really couldn't figure out where Liang Yuan had learned his thoughts. Thinking of Liang Yuan's idea was simply the kind of old-fashioned thinking that had been gone for most of his life in the business world.

"Lao Su, the future market competition will definitely be a confrontation between the entire system. We will only create one or a few leading things, which will be basically useless compared to the entire national market. The domestic market can only be more and more open. In the near future, comprehensive industrial groups like Siemens, ge, and Mitsubishi will enter the country in large numbers. If we want to live comfortably in the future and not be free from the idleness of these giant companies, we can only create our own competitive system."

"Tell me, Lao Su, I'll give you all my memories. You can open your mouth on this project." Liang Yuan said with a smile.

Note 1: The signal machine is a signal light. The railway system is called this to distinguish it from the relatively simple highway signal light.

Note 2: It is the electric switch. There is a gray square box next to the railway switch. A tube-shaped thing extends from the box and is connected to the switch. The thing is an electric switch machine.

Note 3: In order to ensure driving safety, technical methods are used to make the circuit signal machine and the electric switch machine that controls the circuit switch according to certain procedures and certain conditions establish both mutual connection and restriction relationship. This restriction relationship is interlocking. Simply put, after a train exists in a section, the signal of this section will turn red and unpassable, and the switch entering this section will also automatically close.

Note 4: When book friends south of the Yellow River take the express train headed by T, they may encounter the famous 25T model underneath, with a funny arc-shaped dividing plate in the middle of the car, which is unique in the country, and a car is divided into two parts. This is the independent innovation of the Ministry of Railways. (Welcome, your support is my greatest motivation.)
