Railway turnout disease monitoring method, device and system

Abstract

The invention discloses a railway turnout disease monitoring method. The method comprises the following steps: acquiring turnout identification information; determining whether the train travels on the turnout according to the turnout identification information; acquiring a signal acquired by a sensor mounted on the train; when the train travels on the turnout, an impact signal and a vibration signal are separated and extracted from current signals collected by a sensor; comparing the characteristics of the impact signal with preset disease characteristics to obtain first disease information; determining the displacement of the wheel in the vertical direction according to the vibration signal, and obtaining second disease information according to the displacement. The turnout disease information can be determined when a train runs on the turnout, and the turnout disease condition can be monitored timely and accurately. The invention also provides a device and a system, which also have the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of rail traffic monitoring, in particular to a railway turnout disease monitoring method, a railway turnout disease monitoring device and a railway turnout disease monitoring system. Background technique [0002] Turnout is a key part of the railway track, real-time monitoring of turnout disease is the key to avoid traffic accidents. [0003] With the development of modern railway trains in the direction of high speed and high density, the mutual friction, impact and extrusion between the wheels and the turnout track will also increase, which not only increases the possibility of the turnout disease, but also accelerates the The development speed of the turnout disease. The turnout is a movable part and a weak link of the railway track. Compared with the basic rail, the curved point rail of the turnout bears a larger lateral force. Under the action of wheel-rail interaction, external load, environment and d...

Problems solved by technology

Among them, the microcomputer monitoring system mainly monitors the relational graph of the switch action current and time, the state of the track circuit, etc., but due to the lack of monitoring information on the status of the switch, it is relatively difficult to monitor the closeness of the switch, the switching force of the switch, the displacement of the switch and the vibration of the rail. Weak, it is impossible to realize the real-time monitoring of the turnout status; and the imaging technology is to take the image of the turnout when the train is slowly entering the station, determine the characteristics of the turnout through infrared image processing technology, and identify the direction of the turnout

Although this method can identify the road condition information of the turnout, it cannot be combined with the actual operation data. It cannot effectively deal with the abnormal vibration caused by the turnout, and cannot accurately judge the disease state of the turnout.
