Abstract

The invention discloses a rail traffic safety detection method and relates to the technical field of rail traffic safety and measurement and control. Ground radars are deployed in a predetermined monitoring area along a rail; a coordinate system is set, a rail equation is established, and the positions of the radars are marked; radar wave beams (such as laser beams) parallelly scan rail passing surfaces; when prominent suspected obstacles are detected, the direction and distance are obtained, calculation and comparison are conducted in reference to the rail equation, and when it is judged thatthe prominent suspected obstacles are within the rail passing belt range, alarming is conducted; inter-radar scanning cross coverage is conducted to establish synergistic vigilance; according to alarming, illumination is provided, and scene videos are shot; and alarming is further screened, and the normal passing parking time period and the repairing maintenance time period are excluded. A rail is subjected to scanning detection in all-line, all-day, all-weather, full-automation, unattended operation, high-efficiency and high-precision modes, the dangerous obstacles can be accurately distinguished, natural and man-made disasters are found and recorded in time, credible monitoring and pre-warning are provided for rail traffic travelling safety and property protection to guarantee emergencyresponse, the rail traffic safety is improved, the safety of taking travel and freight transport is strengthened, and social and economic benefit value is high.

Description

technical field [0001] The invention relates to the technical fields of rail traffic safety and measurement, measurement and control. Background technique [0002] Rail transit, including intra-city subways, intercity light rails, long-distance railways, and high-speed rails, collectively referred to as railways, has become a major channel for the flow of people and goods in human society. The railway is not only the lifeblood of the national economy, but also the backbone of national defense transportation. The reloading and mobilization of military forces and the concealed maneuvering of ballistic missiles cannot be separated from railways. However, in reality, rail traffic accidents occur frequently all over the world, causing serious casualties and property losses. The safety issues of rail transit mainly include two hidden dangers: one is force majeure due to natural disasters, such as spalling and collapse inside the tunnel, landslides along the line or mud-rock flow ...
