Monitoring and warning system and method for collapse and rockfall along the railway

Abstract

The invention relates to a monitoring and alarm system and method for rockfall monitoring along a railway line. Axle counting devices are installed on rails at both ends of a rockfall monitoring area along a railway line to monitor whether there are vehicles in the area; Collapse and rockfall monitoring and alarm system hosts along the line are connected. The invention can be used in single-track / double-track, electrified / non-electrified railways, various blocked sections, and train running sections with a speed of less than 500km / h. Axle counting devices are installed at both ends of the rockfall monitoring area along the railway to monitor the operation of vehicles. The beneficial effect of the present invention is that the train occupancy in the rockfall monitoring area along the railway can be monitored by the high-reliability axle counting device, the train vehicle can be accurately detected, false alarms caused by the operation of the train vehicle can be eliminated, and the usability of the rockfall monitoring system along the railway can be effectively improved ; At the same time, the sensor of the axle counting device is installed on the railway track, which does not affect the transmission of the signal track circuit and train control information, and can be used in various blocked sections and train control modes, and has practicability.

Description

Technical field [0001] The invention relates to a system and method for monitoring and alarming rockfall along a railway, belonging to the field of disaster prevention monitoring. Background technique [0002] There are many mountains in my country, accounting for about two-thirds of the country's land area. With the implementation of national strategies such as the Western Development, the mileage of mountainous railway lines has shown a trend of rapid growth in recent years. Due to factors such as natural weathering of mountains, rainfall erosion, and artificial destruction of vegetation, mountain collapses and rockfall accidents on railway lines occur from time to time, posing serious safety hazards to railway traffic. [0003] At present, the rockfall monitoring system using the fiber grating vibration sensor has been applied in related projects. The monitoring system uses the grating vibration sensor to monitor the vibration caused by the rockfall falling on the railwa...

AI Technical Summary

Problems solved by technology

[0004] Since train vehicles also generate various forms of vibration during operation, such as vehicle wheel tread damage, vehicle acceleration or braking, and other factors may produce vibrations of various energy levels and frequencies, the monitoring system will inevitably generate false alarms , resulting in low system availability
