Embodiment approach

[0053] It should be noted that this step can be implemented in many ways, one is: acquiring the first time information corresponding to the first current information; determining the working state of the switch according to the first time information. Exemplarily, according to the first current information and the first time information, the current-time characteristic curve ( Figure 1d is the current-time characteristic curve in an exemplary switch conversion process of the present disclosure), such as Figure 1d As shown, the current-time curve is the vertical axis of current and the horizontal axis of time, and the curves are drawn point by point with the current values ​​at 10 millisecond measurement intervals, which contains the electrical characteristics and mechanical characteristics of the turnout process. The time characteristics of the turnout are obtained by analyzing the curve, and the working state of the turnout is determined according to the time characteristic...

Abstract

The disclosure relates to a turnout fault early warning method and device. The method comprises the steps that first current information of an electric switch machine in the current state is acquiredthrough a current acquisition assembly; the working state of a turnout is determined according to the first current information of the electric switch machine, wherein the working state of the turnoutcomprises a normal state or an abnormal state; and when the working state of the turnout is determined to be an abnormal state, alarm prompting is conducted in a preset mode. Therefore, an abnormal problem of the turnout can be found in time according to the current condition of the electric switch machine, accurate data can be provided for turnout maintenance, and a reliable basis can also be provided for positioning of the maintenance problem, so taht the railway operation and maintenance efficiency can be effectively improved.

Description

technical field [0001] The present disclosure relates to the technical field of automatic control, in particular, to a method and device for early warning of a turnout failure. Background technique [0002] At present, the monitoring of railway signal equipment basically adopts the TJWX-2010 signal microcomputer monitoring system. The signal equipment computer monitoring network system jointly developed by the unit. It is used for real-time monitoring of railway and urban subway signal equipment, and the obtained information is sent to the electric service section, sub-bureau or railway bureau through the CAN network of the lower layer and the upper-layer WAN for relevant personnel to search, analyze, count, and summarize, in order to make timely 1. Provide scientific basis for correct maintenance decision-making. It is a necessary equipment for the modernization of railway signal maintenance management. It will provide a technical basis for the reform of the railway signal...
