Auxiliary alarming device of railway grade crossing

Abstract

The invention provides an auxiliary alarming device of a railway grade crossing. The auxiliary alarming device comprises infrared detector sets and an alarm unit, wherein the infrared detector sets comprise a first detector set and a second detector set, the first detector set is arranged on a roadway gate of the crossing, crossing space, 300mm-800mm vertically away from the ground, below the roadway gate is detected, and the alarm unit is controlled to give an alarm when it is detected that people exist; the second detector set is arranged on the ground on two sides of a rail of the crossing, crossing space, with the vertical distance from the ground to the top of a steel rail being 300mm, below the roadway gate is detected, and the alarm unit is controlled to give an alarm when it is detected that an obstacle exists. The auxiliary alarming device is simple in structure, significant in effect, direct and high in efficiency, enhances railway grade crossing alarming functions, improves highway and railway safety conditions, and further improves safety performance of the railway grade crossing; meanwhile, it is guaranteed that transport capacity of the railway can be improved and safe and punctual running transportation is achieved.

Description

technical field [0001] The invention belongs to the technical field of railway crossing safety, in particular to an auxiliary alarm device for railway level crossings. Background technique [0002] At present, the alarm circuit of the railway crossing is that when the train runs to the approaching section of the crossing, the alarm device will give an audible and visual alarm, the crossing fence will be closed, and the railway traffic will be prohibited; Automatic release, the crossing fence is open, and pedestrians and vehicles in the direction of the road can pass. [0003] The currently used crossing alarm device has the following two functions: (1) sound and light alarm when a train approaches the crossing in the direction of the railway; empty. The disadvantages are: (1) the crossing alarm device does not monitor obstacles within a distance of 700mm to 800mm from the ground below the fence; (2) after the crossing fence is closed, whether there is an obstacle between t...

AI Technical Summary

Problems solved by technology

The disadvantages are: (1) the crossing alarm device does not monitor obstacles within a distance of 700mm to 800mm from the ground below the fence; (2) after the crossing fence is closed, whether there is an obstacle between the two fences at the crossing, The alarm device will not alarm

The existing crossing alarm devices have monitoring blind areas, so how to design an auxiliary device for monitoring and alarming the blind areas to further improve the safety of railway crossings has become a research topic for engineers and technicians
