Configuration technology-based railway track circuit and turnout monitoring system

Abstract

The invention discloses a configuration technology-based railway track circuit and turnout monitoring system. The configuration technology-based railway track circuit and turnout monitoring system comprises a PLC and external circuit module, an OPC server side module, a configuration project module and a preset hearbeat detection program, wherein the PLC and external circuit module comprises a 24Vdirect-current multi-output switch power supply, a PLC and extension I / O module, an external relay and an input switch circuit; the OPC server side module is configured by professional OPC software,is driven by corresponding equipment provided through the OPC software, reads and writes PLC variable and comprises the OPC software and an OPC configuration file; the configuration project module isa graphical module based on configuration software development, is combined with read-write and embedded C script logic program of the OPC server side variable, and comprises a global script module, agraphical interface and configuration as well as a variable configuration module. The configuration technology-based railway track circuit and turnout monitoring system can realize visual monitoringof railway track circuit and turnout, has high configurability and extendibility, and is favorable for supplementing real-time property and visualization of railway track monitoring.

Description

technical field [0001] The invention relates to the field of railway monitoring, in particular to a railway track circuit and turnout monitoring system based on configuration technology. Background technique [0002] With the development of information technology and automation technology, efficient, real-time and accurate visual remote monitoring has become an important trend in the development of various industries, and the original manual inspection and manual operation methods will gradually be replaced. At present, there is no visual remote monitoring system for railway track circuits and turnouts. The existing method is mainly based on manual inspection combined with the existing signal system for monitoring. This method cannot monitor the relevant states of railway track circuits and turnouts in real time. , It also lacks convenience, when a fault alarm occurs, the cause of the fault cannot be found in time, and at the same time, the judgment error of the testing pers...

Problems solved by technology

At present, there is no visual remote monitoring system for railway track circuits and turnouts. The existing method is mainly based on manual inspection combined with the existing signal system for monitoring. This method cannot monitor the relevant states of railway track circuits and turnouts in real time. , and lack of convenience. When a fault alarm occurs, the cause of the fault cannot be found in time. At the same time, the judgment error of the testing personnel will also affect the correct judgment of the cause of the fault.
