After Liu Changhe made a summary speech, he left the vehicle garage and walked towards the motorcycle garage where the traction machine head was parked.

"Haiping, why do you think of developing a driver and passenger alarm system?"

Liang Yuan knew very well about his character. After Liang Jiangping learned that Liang Haiping wanted to recommend the driver and passenger alarm system to the chief engineer who came down to inspect the department, he directly transferred the Dongfeng fan head with the alarm device to Liang Haiping. Almost everyone knows the accident in the Harbin Bureau. After Liu Changhe boarded the nose and experienced the alarm device, he immediately realized the function of the device and agreed to Liang Haiping to recommend the invention of the locomotive factory to the department.

"I really don't know where to start this matter." Liang Haiping said with a wry smile.

Liang Haiping can't say that this thing was used by the motorcycle factory to flatter the department after holding the road bureau.

Looking at Liu Changhe's curious gaze, Liang Haiping thought for a while before saying, "I'm not afraid of Director Liu's jokes. In the past, Northeast locomotives were not popular, and I couldn't get work on the road. I didn't have money to pay workers. After I took over the factory, I was forced to come forward and asked for some small jobs in the army. One of them was to produce remote controls..."

Liang Haiping told Liang Yuan about the inviting Su Liangyu in half truth, and then continued: "At that time, the factory had not introduced a 25s model undercarriage, and planned to conduct a variety of operations to develop some automation products around microprocessors."

"Director Liu also knows that I am a railway family member and are more concerned about some things on the road. The accident in Haji was a while ago, which made people feel sorry for me. Once, when I was chatting, I told the engineers of the processor laboratory about the details of the accident at Haji. I didn't expect them to say that it was simple. I just need to make a reminder to the automation system. I let them experiment, but the result was really achieved in a short time."

"But the device in front of me is relatively rough and has not been integrated with the microcomputer control system of the machine head itself."

After hearing this, Liu Changhe laughed and said, "Haiping doesn't have to be embarrassed to say that the noses in the road are not popularized, even the locomotive call response devices that are connected to the outside world, so how can they have their own microcomputer control system?"

"But what you are doing is a trend. The newly introduced 8k locomotive in the department has basically realized the control of the entire machine microcomputer. All data on the machine head can be checked and monitored through the microcomputer display."

"Director Liu's vision is indeed broad. The engineers in our factory also said that they want to move the microprocessor system to the 25s model bottom. They monitor the operation status of generators, air conditioners, and bearings at each bottom. They also plan to change the 25s manual door to an electrical sling door."

Liang Haiping told Liu Changhe about Liang Yuan’s subsequent improvement plan for the 25S model bottom.

Liu Changhe was extremely interested in Liang Haiping's 25s modification. He pulled Liang Haiping for details for a long time, and finally said: "The train control system you plan to make should be combined with the rail-side equipment. I don't know much about this. When the Liaodong Peninsula is in operation, Haiping will come to the road bureau. I will ask you a few experts to talk to you."

The group walked and chatted. Liu Changhe stayed in the motorcycle garage for more than half an hour before finishing the inspection before the joint trial and commissioning.

The next day, Liu Zhigao, Deputy Minister of the Ministry of Railways, and Zhao Tiemin, Chief Secretary, arrived at Sujiatun Train Depot on time on the special train within the Ministry.

Although the leadership level of the Ministry of Railways was relatively high, since it was not officially launched, the local government only sent a deputy mayor in charge of transportation to serve as a ritual reception.

The garage gate parked with the Liaodong Peninsula was closed, and the temporary platform was crowded with people. Liang Haiping, as a vehicle supplier for the Liaodong Peninsula, also got a seat on the rostrum. After a brief welcome, he began a routine speech. The speech of chief engineer Zhao Tiemin was extremely concise, and it ended less than three points, while the speech of Deputy Minister Liu Zhigao was surprisingly long.

Liang Yuan hid under the temporary platform and mingled in the press group, thinking about the joint trial and commissioning of the marshal. He also listened absent-mindedly to the Deputy Minister Liu Zhigao to talk about the significance of the Liaodong Peninsula.

The so-called joint testing and coordination refers to the gradual testing and adjustment of various equipment along the route through trains with different speeds, and fine-tuning some track parameters until the entire line meets the operating requirements of the designed speed. It involves multiple categories such as lines, roadbeds, tracks, etc.

For the train itself, in addition to checking the performance of the train marshalling, the joint testing and commissioning work also needs to detect whether the communication between the on-board sensor and the ground response device along the way is smooth and whether various data transmissions are accurate.

For example, the infrared axle temperature alarm system in Liangyuan plans uses infrared detection devices set up along the railway to scan the part of the train bogie passing in front of the device. If a temperature abnormality is found, it will be directly alarmed. After receiving the warning at the station nearby the device, the dispatcher will call the driver and passenger to stop the car in time.

If the system develops further, data exchange can be performed directly with the train. After the ground device discovers an abnormality, it will also send the data to the nearby station. This will also send the data to the traction head of the marshal. This forms a dual redundant system, avoiding some uncontrollable human factors and greatly improving the safety factor. After truly entering a speed of 200 kilometers per hour, the train marshal itself will also come with a set of axle temperature warning system, which will form a three redundant system.

The Japanese Shinkansen high-speed train has been operating for 47 years without accidents, which is based on this multiple safety detection and protection mechanism.

In 1987, China Railway was still in a toddler, and there was even a switch class. The switches of many branch railways still require uncontrollable factors and a lot of manpower to move and operate, and there is still a long way to go before the electrification era. Therefore, for the 25s model undercarriage, this joint trial and commissioning work is basically in a state of "on-watching" and there is no need to exchange any data with the outside world. As long as you ensure that your car body does not have Level B or above accidents.

As the starting point and end point of the Liaodong Peninsula, Shengjing and Dalian conducted high-density reports on the opening of direct trains between the two cities half a year ago. As Liaoning's largest newspaper, Liaoning Daily, also held a name-based activity for direct trains between the two cities in the form of special issues. This time, the Liaodong Peninsula group made its debut, and four or five print media in the province came to the province. Even Benxi City, which has nothing to do with the Changda Railway, sent reporters from Benxi Daily to appear in the crowd.

When Liang Yuan was bored and counted the media present seventeen or eighteen times, Minister Liu's speech ended. With Liu Changhe's order, two thick iron doors of the vehicle warehouse slowly opened. The head of the Dongfeng fan with big red silk was emitting a faint blue smoke, pulling the entire blue and white group to drive out of the warehouse.

The Chinese people in the 1980s yearned for tall buildings, and people who had never experienced that era could not understand. The peasant brothers at that time had the greatest understanding of city people was that they lived in buildings and had classes. The yearning for buildings was even more unavoidable. The legendary Chinese entrepreneur Shi Yuzhu failed to start a business for the first time because some bigwigs visited the Giant Group and encouraged the Giant Headquarters building to "why can't you be at a height of several floors?", which changed from 18th floor to 72nd floor, and eventually broke the capital chain and dragged down the Giant Group.

Therefore, when the 25s marshalling slowly drove out of the vehicle inspection garage under the traction of the Dongfeng 4, which was reconnected by the two-machine, the reporters around Liang Yuan suddenly became excited.

"My God, double-decker, double-decker, it's actually a train with the second floor"

"Didn't it meant that the air conditioner under the car? The Ministry of Railways has hidden it so tightly this time that it didn't reveal any news."

"Wow, it's so beautiful."

The buzzing sound at the scene suddenly became louder, even overshadowing the slight roar of the Dongfeng fan head. Then the flash lights frequently lit up. Photographers from various newspapers looked for the appropriate angle and took photos.

Liang Yuan looked at the boiling scene, narrowed his eyes and looked at Liu Changhe standing on the stage, thinking that this old guy would be able to create momentum, so that he would make the headlines of the provincial news in this way, which should be finalized. (To be continued...)
