Outdoor online monitoring system for trackside equipment and communication error control method of system

Abstract

The invention discloses an outdoor online monitoring system for trackside equipment. The system comprises a data acquisition unit, a data transmission unit and a PLC protocol converter, wherein the data acquisition unit is used for collecting a frequency shift signal parameter, track circuit voltage, a signal lighting loop parameter, a turnout switch machine action and a notch characteristic parameter of a track circuit; the data transmission unit is used for transmitting data collected by the data acquisition unit to the PLC protocol converter through an LPLC channel; and the PLC protocol converter is used for carrying out protocol conversion, transmitting the converted data to a communication interface extension and transmitting the data to a signal centralized monitoring station machine through the communication interface extension. According to the system, the technical effects of reducing the communication fault coverage, improving the reliability of the outdoor online monitoring system for the trackside equipment and improving the monitoring efficiency are realized.

Description

technical field [0001] The invention relates to the field of rail transit technology research, in particular to an outdoor online monitoring system for trackside equipment and a communication error control method thereof. Background technique [0002] At present, the domestic signal centralized monitoring system collects information on various equipment only limited to indoor local circuits, and there is no outdoor equipment information collection. However, 90% of signal equipment failures occur outdoors. When a failure occurs, because there is no means of monitoring outdoor equipment, maintenance personnel can only manually measure and find the fault point, which takes a long time to troubleshoot. In particular, the fault processing time of the section track circuit is longer, often exceeding 2 hours, which constitutes a D21 accident and seriously interferes with the traffic organization. [0003] To sum up, in the process of realizing the technical solution of the inventi...
