Heavy rain has also delayed the monitoring of high-speed train accidents

At 18:10 on the evening of July 10th, a sudden heavy rain triggered a lightning strike on the power lines from the Tengzhou-Zaozhuang section of the Beijing-Shanghai high-speed railway, which caused a catenary malfunction. Although the railway department initiated the emergency plan, the high-speed rail train was still delayed for about one and a half hours, and subsequent trains were delayed to varying degrees. In fact, the Beijing-Shanghai high-speed rail received attention from all walks of life during the early construction period. Its operation not only refreshed the new record of China's rail transit, but also proved that our country's high-tech level is continuously improving. However, the outside world's doubts about the safety of high-speed rails are overly positive. Ten days after the high-speed rail was officially in operation, a sudden heavy rain raised the safety of the high-speed rail to the highest point. At this time, the safety monitoring system became particularly prominent.

According to the Ministry of Railways, the Beijing-Shanghai high-speed railway has built an all-weather, three-dimensional public security system. Into the station to achieve full-coverage security; the entire line installed 2.85 meters high protection network, and set up a video surveillance system, real-time monitoring of the line and the station, set up an intrusion alarm system in key locations. At the same time, hundreds of individual inspection points were also set up along the way to control accidental dangers. With advanced technology and monitoring equipment, the high-speed rail safety factor has been improved.

Today, high-speed rail has become an indispensable means of transportation for people to travel. In addition to the continuous expansion of the market for security industry applications, high-speed rail security has become an attractive “big cake” in the security market. The seemingly gorgeous cake is not so easy to eat. In the high-speed rail project, surveillance cameras are exposed outdoors all the year round, and therefore require high quality and performance of the products. The camera equipment suffers from severe weather such as heavy rain, thunderstorms, cold winters, and high winds. Therefore, the requirements for defogging, lightning protection, anti-shake, high-definition, etc. are even more pronounced. In this harsh situation, the monitoring equipment is facing a severe test. The upper limit of the use of monitoring equipment in high-speed railways is 5 to 8 years. Since the high-speed rails are closed to management after being put into operation, they also face difficulties in the maintenance process. Second, in order to ensure the safety of passengers and reduce false alarms, the accuracy of surveillance alarms has become the second largest problem to be solved. The accurate monitoring and alarm system is based on the intelligent monitoring system. The functions and application requirements of the intelligent video analysis technology have been written into the "Technical Code for Railway Integrated Video Surveillance System". It is precisely because of the express provisions that almost all high-speed railway monitoring systems in China will use video analysis technology. The Beijing-Shanghai high-speed rail Wuxi East Station has enabled intelligent monitoring systems. With the smart video analysis technology being written into the standard, the application of intelligent video analysis technology in the future will be more and more. In addition to the above, factors such as unattended stations, long-range monitoring, or natural weather prevention in high-speed rail security systems are also important.

The addition of a 3G wireless network has solved the problem of high-speed railway security monitoring and wiring, and high-speed rail communications have evolved from 2G to 3G. Specifically speaking, in terms of railway operations, high-speed railway trains operate long-distance video surveillance, in-vehicle video surveillance, real-time monitoring of train operating conditions, and operational status information, as well as advertising in trains can all be achieved through “high-speed broadband”. Real-time video surveillance system as a powerful tool to deal with and deal with various security risks, is still very important in the rapid development of high-speed railway today.

In view of the high-speed rail safety accidents this time, the high-speed rail monitoring system has placed an important position in both technical and practical applications. But I also want to emphasize that the high-speed rail security monitoring system does not mean that it is safe. It is a device that reduces hazards, prevents problems or is an early warning. Currently limited by the technical conditions, the HSR security system may be able to do so, but in the future development, we have enough confidence in the myth of HSR Security writing the future security.
