Xiaoyuan, things are not as beautiful as you think, at first I thought that the signal factory of the road bureau was far-sighted and splendid. Su Liangyu said with a smile.

"Later, I learned that the signal factory of the Road Bureau was also forced, although it has not yet reached the point of desperation, but it is almost there, and it is more likely to find us or a blind cat to kill the mouse. ”

"Lao Su, can't you make me happy by ten or eight points. Liang Yuan leaned back on the sofa and said weakly.

"Hehe, I'm not afraid to mislead your judgment. ”

"We didn't know the details until later. Su Liangyu took a sip of the teacup before continuing, "The products of the Road Bureau Signal Factory have always been pressed by the Shengjing Signal Factory directly under the Ministry of Affairs, and 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. ”

"When the original unified procurement plan appropriation, the road bureau can also be biased, all the things that the road bureau signal factory can do are purchased at home, anyway, cost accounting is also a matter of the ministry, and the road bureau has little to do with it, after the implementation of the big package, the ministry will decentralize the autonomy and cost accounting at the same time, and the road bureau can not be as before, not considering the cost but only considering the affiliation. ”

"Last year, the Shengjing Signal Factory directly under the Ministry of Foreign Affairs received a sub-project loan of 3 million yuan from the World Bank, and introduced a new type of combined signal (Note 1) from Italy to replace the original lens signal, and also introduced a new type of switch machine voltage monitoring system to transform the domestic ZD6 series electric switch machine (Note 2), which greatly improved the reliability of the switch machine. ”

"It turns out that the signal factory of the Road Bureau has the support of the Road Bureau. I didn't take the technical transformation of Shengjing Signal Factory seriously, and after the big package, each sub-department under the Road Bureau had to carry out independent accounting, and the Road Bureau would decisively adjust the department that could not support itself, or switch production or spin off, and the electric section of the Road Bureau had already been released, in order to control the cost next year. Definitely choose the new signal and electric switch machine of Shengjing Signal Factory. ”

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

As a result, the signal factory of the Railway Bureau took us as a lifesaver and independently developed a railway computer interlocking (Note 3) system. It's a big disguise, it sounds very advanced and exciting. Liang Yuan continued.

"I can't say it's not. Su Liangyu smiled weirdly.

"The real yàn room is completely ignorant of the system engineering of railway signals. After the road bureau signal factory put forward a request for cooperation, we were a little confused, heard the signal factory said that the chip is very widely used in electrification transformation, and it is also a cutting-edge technology in the world, with the information given to us by the signal factory, more than ten people were transferred, and it took four or five days to get a clue in the provincial library. Su Liangyu said.

"Now the electrification transformation of the railway system is being promoted, using the internationally mature automatic signal for indication, the DC electric switch machine for control, and a large number of relays as the logic core. The 6502 electrical centralized railway interlocking system is composed, and the road bureau signal factory cooperates with us, and the slogan is to develop a railway computer interlocking control system with international advanced level. Su Liangyu said with a smile.

"At the international advanced level, this cow is about to fly to outer space. Lao Su, we are really under a lot of pressure in the room. Liang Yuan said mockingly.

Looking at Su Liangyu's puzzled expression, Liang Yuan grabbed his hair, 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 were skimmed, the slogan satellite went to the sky first. ”

Liang Yuan ridiculed the signal factory of the Road Bureau, purely because the Ministry of Railways saw too many high-profile slogans in the previous life, so that the subconscious formed a reflex arc of intuitive disgust, just like the 25T passenger car hyped by the Ministry of Railways in the late nineties, which is obviously the BSP high-speed car bottom designed by Bombardier Canada for the Belgian railway, after the introduction of the Ministry of Railways, the electric folding sliding door was changed to an electric plug door, and a funny divider was added in the center of the carriage, it became a quasi-high-speed car bottom independently developed by China (Note 4), countless technologies" Expert" has solved the title and the funding here, but any normal person, as long as he is a little ashamed, will have a natural aversion to this shameless behavior.

Su Liangyu smiled and said: "The signal factory of the Road Bureau is not easy, Xiaoyuan has to understand more." ”

Being able to put down the high shelf, and the family members of the enterprise take the initiative to fight for the opportunity to save the enterprise, it is not a big outlier in the state-owned enterprises in the eighties, and there should be rescue value.

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

Clapping the thick report in his hand, Liang Yuan said: "Most of the space here is talking about how advanced the computer interlocking system is, and there is no reference value in technology." ”

"We have done a brief simulation, if you want to build a full-road computer interlocking system, a single railway signal and electric switch machine will need more than 10 million chips, if you add the car bottom, nose, operation, electrical and other departments, the final market is not clear to me. ”

"However, from a technical point of view, the system required by the railway is not difficult, except for a small number of high-performance processors for the aggregation of the number of high-performance processors we can't solve, the remaining 99%, the current chip real room can be solved, the problem lies in the integration and debugging of the whole system, even if it is to build a demonstration line, the whole system also contains tens of thousands or even millions of chips, to ensure that these chips do not conflict in a network, safe and stable operation This is the most difficult. ”

"Yesterday's train sand table was only four trains, and when we debugged the system last night, we found nearly 100 bugs alone. ”

Liang Yuan rolled the information in his hand into a roll, gently tapped on the armrest of the sofa, thought for a moment and said with a smile: "I was almost deceived by Lao Su, Lao Su, you just said that this job is actually a hard job, and the pure technical difficulty is not too high, mainly because the manpower is not enough." ”

Su Liangyu smiled and said, "I don't say it, Xiaoyuan didn't guess it too." ”

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

"Computer migrant workers?" Su Liangyu repeated suspiciously.

Liang Yuan patted his head, and remembered that it would take at least 15 years for TI migrant workers and code farmers to step onto the stage of history, and now there are very few people who can do this business, and they belong to high-tech talents.

"Computer migrant workers. Liang Yuan explained.

"Haha, Xiaoyuan's analogy is very appropriate. The project didn't require much creative thinking, and the nature of the work was very similar to that of a step-by-step construction worker. ”

"Lao Su, let's talk about it, how many people and how much money are needed for this project, 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 also tell you, the Northeast Locomotive Factory intends to produce gas turbine locomotives, this project is rare in the world, and we have no foreign roads to learn from." ”

"And even if the gas turbine locomotive is successfully developed, in addition to the advantages of using the legendary Qinghai-Tibet Railway, when applied in the plain area, it is much worse than the diesel locomotive in terms of fuel economy, and it will take at least five to eight years to expect the gas turbine locomotive to technically improve the fuel economy. ”

Su Liangyu listened to Liang Yuan's words and pondered for a moment and said: "Xiaoyuan, you are planning to develop a new generation of railway signal control system through guò, and rigidly bundle the gas turbine locomotive into the entire system, right? As long as we complete the computer interlocking system in some areas and interact with the train marshalling and locomotive, even if the Ministry of Railways wants to promote the electric locomotive in the future, we must consider the compatibility of the whole system." ”

Liang Yuan gently patted the armrest of the sofa and said, "Lao Su, you're not lazy, you're basically close to the level of a genius." ”

"The more popular we promote the new signal system, the greater the dominant position, no matter which country's head comes in, as long as you want to join the signal network of the Ministry of Railways, you must first pass through our pass, and then we can sneeze casually, the compatibility of the light system can toss him for a year or two, as long as the situation has been in a stalemate for five or six years, and so we have technically got the gas turbine locomotive, it is a good time to fish in troubled waters." ”

Su Liangyu looked at Liang Yuan and waved his hand excitedly as he spoke, and shook his head speechlessly, but he was very puzzled in his heart, he really couldn't figure out where Liang Yuan's ghost thoughts were learned, thinking that Liang Yuan's idea was simply the kind of old fritter thinking that he had been rolling on the business sea for most of his life.

"Lao Su, the future market competition is definitely the confrontation between the whole system, we only make one or a few leading things relative to the market of the whole country, basically useless, the domestic market can only be more and more open, the near future like Siemens, GE, Mitsubishi this comprehensive industrial group will enter the country in a big way, if we want to live comfortably in the future, not by the idleness of these giant enterprises, we can only make our own competition system. ”

"Say, Lao Su, I'll hand over the old bottom to you, and you can open your mouth on this project. Liang Yuan said with a smile.

Note 1: The signal is a signal light, and the railway system is called so to distinguish it from the simpler road signal light.

Note 2: It is an electric turnout, there is a gray square box next to the railway turnout, and a tubular thing sticks out of the box to connect to the turnout, and that thing is an electric switch machine.

Note 3: In order to ensure the safety of driving, through the technical method, the approach signal and the electric switch machine that controls the approach switch are established according to a certain procedure and certain conditions, and the relationship between them is interconnected, and the relationship is interlocked, simply put, after a section of the train is stored, the signal of this section will become red and impassable, and the turnout entering this section of the line will also be automatically closed.

Note 4: When the book friends south of the Yellow River take the express train with the start of T, they may encounter the famous 25T car bottom, there is a funny arc-shaped dividing plate in the middle of the carriage, which is the only one in the country, and a carriage is divided into two parts, which is the independent innovation of the Ministry of Railways.
