Embodiment Construction

[0030] The invention provides a method and device for monitoring rail damage of a turnout, which solves the problem that the rapid development of tiny cracks cannot be effectively identified when the track circuit and large-scale rail inspection vehicles are used to detect the damage of the rail in the prior art. The technical problem of detecting the blind area can effectively identify the tiny cracks on the rail of the turnout and overcome the detection blind area.

[0031] In order to solve the above-mentioned technical problems of detection blind spots, the general idea is as follows:

[0032] This scheme adopts a turnout rail damage monitoring device, including sequentially connected sensors, monitoring extension, monitoring host and data center, wherein the sensor is installed on the turnout rail, and the sensor sends the collected characteristic data to the monitoring extension. The feature data is processed, and the processing results are sent to the monitoring host. T...

Abstract

The invention relates to the technical field of railway equipment and provides a turnout steel rail damage monitoring method and device. The device comprises a sensor, a monitoring extension, a monitoring host and a data center, wherein the sensor is mounted on a turnout steel rail and transmits collected characteristic data to the monitoring extension; after processing the characteristic data, the monitoring extension transmits processing results to the monitoring host; the monitoring host processes the processing results and performs appointed distribution; the data center manages the entire device and controls a client terminal according to reprocessed data The turnout steel rail damage monitoring device solves the technical problem that, when rail circuits and large rail inspection vehicles are utilized to detecting damage of steel rails, rapidly-developed tiny cracks cannot be identified effectively and accordingly lead to non-detection zones. Further, the turnout steel rail damage monitoring device can effectively identify the tiny cracks on the turnout steel rail to overcome the non-detection zones.

Description

technical field [0001] The invention relates to the technical field of railway equipment, and provides a method and a device for monitoring damage of a turnout rail. Background technique [0002] High-speed turnout rails are very important in high-speed railway infrastructure and key facilities that affect driving safety. High-speed turnout rails have always been the weak link in the line and the key and difficult point in line maintenance. Therefore, the high-speed turnout rail monitoring system is very necessary, and it is also urgently needed for high-speed railway maintenance and repair. [0003] The traditional rail damage detection is mainly completed by the railway track circuit and the rail damage inspection vehicle. The rail damage detection principle of the railway track circuit is that when the rail is damaged, the characteristic parameters of the railway track circuit change. Rail damage such as breakage that may occur; rail damage inspection vehicle, its princi...
