Embodiment Construction

[0028] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] An embodiment of the present invention provides a broken rail monitoring system, which can monitor a track broken in real time and accurately, and is especially suitable for monitoring a broken rail on a sharp rail.

[0030] In this embodiment, the occasion of monitoring the broken rail of the switch rail is taken as an example to describe in detail. The structure of the broken rail monitoring system is as follows: figure 1 As shown, it includes a monitoring host 1, a plurality of track extensions 2 and a coating 3 arranged on the track surface. Among them, the monitoring host 1 is generally installed in each station to manage all the up and down switches of the entire station. The number of track extensions 2 of the track extension 2 can be set according to actual needs. When monitoring the broken rail of the switch rail, One can b...

Abstract

The invention discloses a monitoring system for rail breakage. The monitoring system comprises a monitoring host computer, at least one rail slave computer and a plating layer arranged on the surface of a rail. The plating layer includes a sensing layer. The rail slave computer is connected with the sensing layer to form a detection loop, and the rail slave computer is connected with the monitoring host computer. When determining that the detection loop is disconnected, the rail slave computer sends rail breakage warning information to the monitoring host computer. According to the monitoring system, the plating layer is arranged on the surface of the rail, the detection loop formed by the plating layer on the surface of the rail and the rail slave computer is monitored, and therefore the rail breakage can be monitored accurately in real time.

Description

technical field [0001] The invention relates to the technical field of track monitoring, in particular to a broken track monitoring system. Background technique [0002] As an essential part of rail transit, rails occasionally break under the influence of environmental changes, rail fatigue, defects, and mechanical impact of trains. As the movable part of the railway rail, the point rail plays an important role in carrying the train and guiding the train. From the perspective of kinematics and mechanics, the impact of the point rail is greater than that of the ordinary rail, and its mechanical strength is weak. Compared with ordinary steel rails, the probability of rail breakage is greater. [0003] The main equipment for train operation control widely used at present is the track circuit, and an important subsidiary function of the track circuit is real-time broken track detection. According to the working principle of the track circuit, the occurrence of broken rail is d...
