Chapter 234 Joint Debugging and Testing
High-speed railways are composed of multiple systems, including subsystems such as power supply and transformation, catenary, EMUs, communications, signals, roadbeds, bridges, tracks, and passenger services.Joint debugging and joint testing is to use high-speed comprehensive testing trains and related testing equipment to run back and forth at different speed levels on the line, to repeatedly test, debug, and verify the status of each system and the matching relationship between systems, so that the functions and structures of each subsystem Complete and reasonable, so that the overall system function of the high-speed railway can be optimized.

Joint debugging and joint testing is to comprehensively test various systems such as line engineering, high-speed EMUs, traction power supply, communication signals, disaster prevention monitoring, operation scheduling, and passenger transport services of high-speed railways.This is like exercising an excellent volleyball team. It is not only necessary to ensure that "each athlete" has good physical and technical characteristics, but also to ensure that the "team" has good coordination ability, so as to meet the safe, high-speed and stable operation of high-speed trains. The joint commissioning and joint test is to use high-speed inspection trains and other test equipment to gradually test the track, communication, signal, catenary and other equipment along the line before the railway is put into operation, and adjust the defects found according to the test results .This is a necessary test for the opening of the high-speed rail, which can ensure the safe operation of the high-speed rail

Joint commissioning and joint testing is the technical preparation before the high-speed railway is put into operation.

Under the unified deployment of the construction unit of the Beijing-Zhangjiakou high-speed railway, various professional and technical personnel have invested a lot of work in the preparation of the joint debugging and joint testing technical plan. The joint debugging and joint testing work of the Beijing-Zhangjiakou high-speed railway was first listed The 2019 high-speed railway comprehensive inspection train departed from Changping Station of the Beijing-Zhangjiakou High-speed Railway, and the joint commissioning and testing work of the Beijing-Zhangjiakou High-speed Railway has started since then.The joint debugging and joint test work is organized by the operating unit and the China Academy of Railway Sciences Group Co., Ltd. implements the test, and the engineering construction unit and the four-electricity system integration unit jointly participate in the test and test.

Ren Shuxia also came to the scene with various professional engineering and technical personnel from the headquarters. They took the high-speed railway comprehensive inspection train and tested their own professional equipment together. Zhang Quanwu smiled and said to Ren Shuxia:
"Mr. Ren, I am very confident in our catenary expertise. Since the opening of our Beijing-Zhangjiakou high-speed railway catenary, we have invested a lot of high-tech products. In the process of unit project acceptance in the near future, are there the fewest problems?"

"Minister Zhang, you are so funny. You are the head of the engineering department of our headquarters. Why, you only pay attention to your professional catenary. Isn't our signal professional doing well?" Old He, the chief engineer of the signal professional, asked with a smile.

"Yes, yes, without our communication major, how would we carry out the dispatching work?" Xiao Qi, the chief communication engineer, was not convinced.

"Look, Minister Zhang, as soon as you say this, it will make everyone unhappy? You, it's too early to be happy. Today is the first day of our Beijing-Zhangjiakou high-speed rail joint commissioning and joint trial work. It’s not started yet, so why, I’m complacent, you, you can’t be too proud, everything is based on scientific debugging data!” Ren Shuxia said to Zhang Quanwu with a smile.

"It's better that Mr. Ren stands tall and can see far. If it's a mule or a horse, don't you know if you pull it out?" Lao He gave Zhang Quanwu a blank look after hearing Mr. Ren's words.

"Mr. Ren, the lesson is right. Let's stop talking and look at the test results together?" Zhang Quanwu didn't dare to talk and laugh loudly at this time, and his eyes were fixed on the computer screen on the test vehicle. , hold your breath, and stare at it with all your attention... The others didn't dare to be careless, they didn't dare to blink their eyes while taking out their notebooks, it was very serious.

In an instant, there was a serious and tense atmosphere in the car compartment. At this time, the commander Mao Shaohua accompanied the leader of the construction unit Mr. Yang and the director Wen Jiayuan also came to the big guys. Mr. Wen looked serious when he saw everyone. , couldn't help laughing and asked:

"Mr. Ren, what, I'm still worried about the work I'm doing. Look at each of them, they all have serious faces. Why are you so nervous? Some time ago, the quality inspection of our unit's project will not be Is it just finished, do you have many questions?"

"Mr. Yang, Mr. Wen, Mr. Mao, you are here too!"

"Yes, today is the first day of joint commissioning and testing of the Beijing-Zhangjiakou high-speed railway. No, Mr. Yang, Mr. Wen, don't worry, you have to come to see it yourself?" Mr. Mao said with a smile.

"Yes, Xiao Ren, how is the detection effect now?" Mr. Yang asked with a smile.

Ren Shuxia took a peek at Boss Wen. She knew that Boss Yang was also an old expert in the power supply system. She knew in her heart what the old leader was most concerned about at this time?So she pointed to the schematic diagram of catenary pantograph and catenary detection on the display screen, and explained with a smile:

"According to the above, the pantograph-catenary relationship of our Beijing-Zhangjiakou high-speed railway is not bad. The pantograph and the catenary are in good contact, and nothing has happened yet."

"Before the high-speed rail is put into operation, through comprehensive inspection of trains and inspections to confirm trains, dynamic inspections are used to comprehensively test the interfaces and matching relationships between various systems and related systems, and to evaluate and verify traction power supply, catenary, telecontrol, communications, signals, The performance or function of systems such as customer service, disaster monitoring, and earthquake early warning and monitoring systems, verify the applicability of structural engineering such as tracks, turnouts, roadbeds, bridges, tunnels, and sound barriers, and evaluate comprehensive grounding, electromagnetic environment, vibration and noise, and phase separation devices, etc. Whether it meets the requirements of relevant standards, provide technical support for the debugging and optimization of all business systems and the overall system, make the functions and performance of each system and the overall system meet the standard requirements, and provide important technical support for the opening and operation.”

When Mr. Yang said this, he suddenly raised his tone, and continued:
"Our Beijing-Zhangjiakou high-speed rail joint commissioning and joint test covers 17 major items and more than 6000 parameter items of various systems such as high-speed railway fixed facilities, mobile equipment, traction power supply, train control, and passenger transport services, involving operating units, construction units, testing units, hosts, etc. A total of more than 2000 people from dozens of units, including factories, design units, construction units, supervision units, and railway public security, participated in various tasks such as testing, fine-tuning, and security, and escorted the smooth implementation of the Beijing-Zhangjiakou Expressway joint commissioning and testing. Here, on behalf of the construction unit, I would like to express my high respect to the hard work of the engineering and technical personnel on the front line of construction, and say thank you to you!"

All the units and professional engineers and technicians who participated in the joint commissioning and joint test in the carriage felt warm after hearing Mr. Yang's words. The big guys knew very well that they could participate in the construction of China's first intelligent high-speed rail. How lucky it is.Therefore, everyone knows in their hearts that this project must be done well. Only by doing their own work well can they live up to the ardent expectations of the leaders. Beijing-Zhangjiakou high-speed rail, I participate, I am proud!The spiritual concept is always in the hearts of every participant in the construction of the Beijing-Zhangjiakou high-speed rail project...

Ren Shuxia knew that once the high-speed rail project reached the stage of joint commissioning and joint testing, it meant that the construction of the project was coming to an end. According to the usual practice, the heavy construction tasks on the front line were basically completed, and the rest of the work was entirely up to the front-line engineers and technicians. For the problems found in the first-line joint debugging and joint test stage, one must always keep a clear mind, solid theoretical knowledge, and rich construction experience, and find the way and method to solve the problem in the shortest time. This is also a test of the comprehensive ability of a construction company. The critical moment, therefore, she knew that, as the chief engineer of the Beijing-Zhang Sidian Headquarters of the group company, she could not slack off for a moment during the period before the opening of operations, and she had to keep a clear mind at all times.

Ren Shuxia looked at her slightly protruding belly at this time, couldn't help stroking her hands through her clothes, and muttered softly in her mouth:

"Son, at this critical moment, you have to be good, and don't make trouble for mother?"
