China News Service, Kunming, February 12th, Title: Railway “CT Doctor”: Analyzes 3,000 photos every day to ensure passenger travel safety
Author Fanyue
On the morning of the 12th, in the testing laboratory of the Yuxi power supply section of China Railway Kunming Bureau Group Corporation, the sound of keyboard tapping and mouse clicking echoed constantly. Testing analysts are like railway "CT doctors", analyzing and comparing black and white pictures on the railway line contact network. Each person has to check up to 3,000 pictures every day to ensure the safety of passengers.
During the work, Liu Fangqiang, a testing analyst at the Yuxi power supply section, and more than 10 colleagues stared at the computer screen, zooming in and out over and over again with the pictures of the China-Laos Railway, Kunming-Dali Railway and other lines displayed on the computer. , repeated comparison and inspection to screen for equipment hazards that affect the safety of railway contact network power supply and driving.

Liu Fangqiang, 29 years old, has been working for 7 years. After becoming a 6C inspection analyst in 2021, he is well aware of the importance of technology to ensure safety. In just half a year in the new position, he will inspect and analyze the operation instructions and catenary defects. The analysis items of the grading dictionary and each component of the catenary can be "clearly understood at a glance".
Liu Fangqiang's testing laboratory has a total of 33 testing analysts. Their job is to analyze the "6C system" and the videos and photos captured by drones to find out the equipment hazards that affect the safety of railway power supply and eliminate them in a timely manner. . "6C System" is the abbreviation of "Railway Power Supply Safety Detection and Monitoring System". It can achieve comprehensive detection and monitoring of railway power supply equipment in all aspects and coverage, just like CT scans in hospitals.
"Every time the system will take and send back tens of thousands of massive photos, we have to repeatedly judge and record each photo, and conduct full coverage and analysis of various testing and monitoring data of the on-site equipment three times in the morning, noon and evening, and conduct accurate analysis of the equipment status. ." Liu Fangqiang said that making accurate judgments on each photo is a test of eyesight.
The catenary equipment on the railway mainly provides traction power to the trains. In order to ensure the normal operation of the catenary equipment, the "health status" of the catenary must be monitored at all times. Liu Fangqiang introduced that during daily inspections and maintenance, many safety hazards cannot be discovered through naked eyes. Therefore, inspection analysts need to analyze and judge the returned videos and photos to find out the equipment defects that may affect the lines.
During the Spring Festival travel season, in addition to boarding trains to monitor catenary data and analyzing data, inspection analysts also need to conduct drone inspections of power lines in sections. Most railway power equipment is distributed among mountains and canyons. Inspection drones with high-definition cameras play an extremely important role in fault finding, line inspections, external environment inspections, etc., overcoming the limitations of terrain and distance, and truly Go to "three-dimensional inspection".

During the Spring Festival travel period, the passenger flow is large and the catenary equipment is put to great test, so Liu Fangqiang's workload increases accordingly. "We keep our eyes glued to the computer every day, and our energy is often in a state of high concentration. Tiredness is common. But every time I see the train passing safely, I feel very satisfied. All the hard work is worth it." When talking about the results of the work, Mr. Liu Fangqiang It is full of joy.
During the Spring Festival this year, Liu Fangqiang and his colleagues needed to complete the inspection and analysis tasks of 2,600 kilometers of catenary equipment, with a total of more than 1.6 million photos, and conduct drone inspections of nearly 4,500 kilometers of power lines in the pipeline to eliminate every problem that affects the safety of train operations. hidden dangers to ensure the travel safety of every passenger.
