Point switch fault prediction method and fault prediction system

Abstract

The embodiment of the invention discloses a point switch fault prediction method and prediction system. The point switch fault prediction method comprises the steps of obtaining the mechanical part stress information of a point switch, wherein the mechanical part stress information at least comprises the bearing pedestal static stress; at least comparing the bearing pedestal static stress with a bearing pedestal static standard stress, wherein the bearing pedestal static standard stress is the difference between the standard close contact force and the current actuating rod driving force; andwhen the static stress of the bearing pedestal exceeds a first early warning range of the static standard stress of the bearing pedestal, carrying out tight attachment force early warning. According to the embodiment of the invention, the problems that the existing turnout switching equipment cannot carry out close contact force fault early warning and the manual maintenance wastes time and laborare solved, the detection and early warning of a mechanical structure in the point switch are achieved, it is guaranteed that the turnout switching equipment can be overhauled in time before breakingdown, and the traffic accidents caused by the turnout switching equipment can be effectively avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of rail transit, and in particular to a fault prediction method and a fault prediction system for a switch machine. Background technique [0002] The characteristic of the rail transit field is the singleness of the track, that is, the train can only travel along the current track. In order to meet the capacity requirements, the parallel mode of multiple tracks is an inevitable choice. In the case of multiple tracks, the train must For track switching, the function of the switch switching equipment is to enable the track at the switch switching point to flexibly change the track through the push-pull action on the track, and the train to switch lines. [0003] The turnout switching equipment mainly includes two parts, namely the outdoor turnout switch machine and the indoor turnout control circuit. The outdoor part is the action response part, and the indoor part is the control par...
