Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rail transit foreign matter intrusion monitoring, in particular to a rail foreign matter intrusion sensing and alarming system. BACKGROUND

[0002] In rail transit, the occurrence of railway traffic accidents due to foreign matter intrusion into the running guide rail poses a risk to the safe operation of trains and disrupts the normal operation of the railway system. Personnel in the maintenance section need to conduct daily inspections to ensure safety on the railway line, which consumes a large amount of manpower and resources. During actual daytime railway operation, personnel cannot enter the rail operation section to ensure normal train operation, which results in personnel being unable to timely discover and alert train personnel to take appropriate safety measures when foreign matter appears on the rail. Traditional monitoring methods include one using an electric grid to monitor falling objects on an overpass road or bridge and one installing a camera along the line to implement picture monitoring. The patent document with the application publication number CN119785325A discloses a rail foreign matter detection system based on machine vision, which effectively reduces the burden of manual inspection. However, due to the complex environment of the section line, the section line may also need to pass through culverts and tunnels, and many environments do not have conditions for camera installation. Such a solution has significant implementation limitations. SUMMARY
