After listening to Liang Yuan, Su Liangyu smiled and said, "Then I'm welcome." ”

Su Liangyu stretched out three fingers and shook and said: "Not counting the power invested in the chip room now, to make the project close to the practical process of engineering, Xiaoyuan needs to invest at least 300 people, and if you count the bottom of the car and the traction head, it will take at least 500 people to make the project officially operation." ”

Liang Yuan smiled bitterly and said: "At present, the Railway Research Institute directly under the Ministry of Education, all the technical personnel add up to less than 1,000 people, Lao Su, you have directly turned the scale of the project team into half of the Railway Research Institute, where can I find someone." ”

"Hehe, that's your problem, but there are fewer people, which means that the development progress will be slower. Su Liangyu said with a smile.

In order to take out the samples of the air purifier before the Canton Fair in May, Su Liangyu threw the matter of forming a project team with the Road Bureau Signal Factory to Liang Yuan, but Su Liangyu still had a conscience and transferred Wang Xin, the backbone of the chip room, to be in charge of specific affairs for the time being.

In the 80s, the railway computer interlocking system, not to mention the signal factory of the Railway Bureau, searched all over the country, and only the communication and signal research institute under the Railway Research Institute had some relevant talents, and Liang Yuan planned to bundle the gas turbine locomotive into the entire railway system, it was far from enough to rely on computer interlocking, at least the locomotive signal (Note 1) and the train operation monitoring device were developed together, and then integrated into the huge signal network formed by the ground signal agency.

Liang Yuan took the thin development plan drafted by the Road Bureau Signal Factory. I shook my head.

The Road Bureau Signal Factory simply listed the ground signal and electric switch machine after replacing them with chip control. In terms of cost and reliability, he introduced the computer interlocking system put into use in the underground transportation line of Nanjing Meishan Iron Mine in 84 years, and planned to integrate the new signal and switch machine with the Meishan Iron Mine system in the future to build a new railway signal management system.

Liang Yuan, who has a clear understanding of the future, knows that the development plan of the Road Bureau Signal Factory is about the same as a joke.

The progress of China's railway system began with the Yangzhuang Massacre, the largest railway accident in the history of the People's Republic of China, when 368 trains from Xi'an to Xuzhou collided with 87 trains from Nanjing to Xining near Yangzhuang Station in Lankao County, Longhai East Line. The accident killed 106 people, slightly injured 171 and seriously injured 47.

The cause of the accident was that the two drivers of the 368 train, Ma Xiangchen and Yan Jingfa, were asleep at the same time when they approached Lankao Station. The 368 that were supposed to be waiting at Lankao Station crossed the blood-red outbound signal and rushed out of Lankao, and finally the "unmanned" 368 collided with 87 at Yangzhuang Station.

After the accident, the world was shocked, because it was on the eve of reform and opening up, the central government attached great importance to the accident, and at the same time punished the two drivers who caused the accident by sleeping illegally, it also gave the relevant management personnel, including the vice minister of the Ministry of Railways, the punishment of administrative demerits .......

After the "Yangzhuang Massacre", advanced railway management concepts such as locomotive signaling system and automatic parking system were put on the work agenda by the Ministry of Railways. However, due to the country's weak electronic infrastructure and the backward management thinking of the railway system (Note 2), there was almost no progress in this work throughout the eighties.

A few days ago, in order to appease the automatic braking system made by the ministry, Liang Yuan was added by the Railway Research Institute with a motor to control the brake duct, which became his own achievement, and hyped up two issues in the "People's Railway News", and then began to promote it in the passenger nose with a series of international advanced titles.

In fact, it was not until the mid-nineties that the Ministry of Railways introduced ...... in France After the general locomotive signaling system, the problem of locomotive signaling is solved. As for the automatic parking system, although the Ministry of Railways swears that after entering the new century, the self-developed CTCS (Note 3) system has solved the problem of automatic train parking under dangerous conditions, but the world-famous high-speed rail accident in Wenzhou is tantamount to a resounding slap in the face of the Ministry of Railways.

Since Su Liangyu has the ability to solve the needs of the railway signaling system in hardware. Liang Yuan plans to officially enter the railway signal industry, so naturally he can no longer use the development plan full of loopholes made by the Road Bureau Signal Factory.

The next few days. Liang Yuan honestly stayed in the 909 community, trying to recall the CTCS system promoted by the Ministry of Railways after the new century.

The CTCS system consists of a large number of transponders, track circuits, wireless communication networks (G**-R), train control centers (TCC)/radio block centers (RBC) and other parts. The core of the whole system lies in the transponder and the receiver, the transponder can transmit the information of the ground signal to the receiving equipment of the nose, and the ground signal is through the guò track circuit receiving device to check the occupancy of the interval track, through the guò chip judgment, command the signal to make relevant signal response.

Liang Yuan stayed in the 909 community for three days before he put into words the principles, equipment architecture, short-term planning, long-term planning and other issues of the CTCS system in his previous life, and restored the entire CTCS system on the framework.

On February 23, Liang Yuan returned to the Science and Technology Park with the fruits of his labor in the past few days and a stack of handwritten thick materials, and routinely went to Su Liangyu's office first, but Liang Yuan, who pushed the door in, found a middle-aged man with glasses sitting on the sofa where Liang Yuan usually sits.

"Su Gong, my uncle asked me to give this to you. Liang Yuan shook the text in his hand and said.

Su Liangyu motioned for the man with glasses to wait a moment, and took the text handed over by Liang Yuan...... Train operation control system. Su Liangyu looked at the few big words on the cover of the article and read them out casually.

Liang Yuan shamelessly removed the "C" of the Chinese train control system in his previous life, representing China's son and mother, and replaced it with the first pinyin "L" of his surname. ”

Su Liangyu picked up the text and looked at it intently.

In Liang Yuan's plan, the LTCS system is divided into five stages, the first is to build the foundation, through a large number of digital signals, switch machines, general locomotive signals, train operation monitoring devices to form the basic digital system of the entire railway, during this period the train operating speed does not exceed 100 kilometers.

After the construction of the basic system, in the development of the main locomotive signal, the train marshalling relies on the observation of the ground signal operation, becomes the locomotive signal operation in the car, and at the same time establishes a safe operation monitoring and recording device, relying on the comparison and judgment with the historical operation record and signal, the anti-overspeed function of automatic deceleration can be realized, and the operating speed of the train can be increased to 120 kilometers per hour after the completion of the anti-overspeed system.

Finally, based on the track transmission information, the train operation control system designed by the train-ground integration system is adopted. It can realize the integration of train command-computer interlocking-train control, section-station integration, communication-signal integration and mechatronics. Section scheduling can intuitively grasp the real-time situation of all signals, turnouts and running trains in the section at any time, and can find the signs of accidents that threaten driving safety at the first time.

Twenty minutes later, Su Liangyu let out a sigh of relief, raised the information in his hand, and said to the man on the sofa: "Meng Gong, there is just a copy of the article on building a railway signaling system, Meng Gong can take a look, and after reading it, we will discuss which unit will lead the development of a new signaling system." ”

Note 1: Because the ordinary signal is installed on the ground, it is limited by the terrain such as railway curves and tunnels, which brings certain difficulties to the driver. Especially in the rain and snow, wind and sand, fog and other harsh climatic conditions, the ground signal is not clear, the locomotive signal is the sensor installed on the traction head, after receiving the signal of the ground signal, after decoding the locomotive signal machine continues to display the same signal as the ground signal in front.

Note 2: In the 80s, even portable signal lights were high-tech products in the railway sector, and red and green pennants were used to command trains.

Note 3: CTCS is the train operation control system of China Railway.
