Description
Technical Field
The invention belongs to the technical field of security alarm and railway signal, and particularly relates to an alarm method, equipment and a system for illegal intrusion at the end part of a high-speed railway platform.
Background
The high-speed railway passenger transport platform has the characteristics of large passenger flow, dense personnel, complex passenger flow environment and the like, the end part of the platform is a weak area for safety monitoring of the passenger transport platform, and the passenger transport manager of the platform is difficult to find that the personnel illegally enter the railway section through the end part of the platform in the first time, and particularly when the platform has no passenger on/off operation, the end part of the platform has no following monitoring. Once a person illegally enters a railway section through the end part of the platform, the railway passenger transport operation order is seriously influenced, and great potential safety hazard is brought to railway transport.
At present, the protection of the end part of a high-speed rail station generally adopts the all-weather guard of an attendant or the all-day monitoring of a video.

However, based on manual patrol, the platform safety is centrally supervised in the form of talkback and telephone when an emergency occurs, and the defects of blind zones, alarm condition transmission and untimely disposal exist in patrol. If video all-day monitoring is adopted, the video lacks an analysis function, so that a worker stares at a monitoring picture for a long time to generate visual fatigue, certain passenger transport management negligence exists, and the defect of untimely processing exists once an alarm condition is found.
In order to prevent people from illegally entering a railway section, an intelligent intrusion alarm device at the end part of a high-speed railway platform needs to be arranged by means of advanced information technology, all-weather and automatic monitoring on the end part of the platform can be realized by means of radar, video and radio frequency, and an acousto-optic alarm is sent to illegal intrusion behaviors in real time to restrain the behaviors of passengers at the platform. The video monitoring system can call out historical videos of the alarm records within corresponding time at any time, so that evidence of the intrusion behavior is more convenient and faster.

Therefore, the movable platform anti-intrusion equipment arranged at the end part of the railway platform can save the station operation cost and effectively avoid potential safety hazards caused by artificial intrusion of the end part. The intelligent level of railway passenger service and production organization can be improved by assembling the intrusion early warning alarm device on the end part of the platform, the operation mode of the railway passenger station is optimized, the requirement of intelligent railway development is met, and powerful support is provided for the intelligent railway passenger development.
