Wireless shunting locomotive signal and monitoring system maintenance management method

Abstract

The invention discloses a wireless shunting locomotive signal and monitoring system maintenance management method. An analysis center is remotely connected with each station locomotive device in a wireless shunting locomotive signal and monitoring system by utilizing an existing microcomputer monitoring network channel; and the analysis center performs maintenance management on each station locomotive device. The method comprises the steps of monitoring a running state of each station locomotive device, and when an alarm signal sent by a station locomotive device is received, backing up important data of the corresponding station locomotive device; and querying related data of the specified station locomotive device through an online query instruction, obtaining historical record data meeting a retrieval condition and called by each station locomotive device by sending a retrieval instruction to each station locomotive device, and assessing a health state of each station locomotive device. The method can improve efficiency of device maintenance, upgrading and management, and ensure security application of the system on site.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method for maintaining and managing a wireless shunting locomotive signal and monitoring system. Background technique [0002] The STP wireless shunting locomotive signal and monitoring system is a computer integrated control system used for displaying shunting locomotive signals and monitoring shunting operations at railway stations. The ground cabinets of the system are connected to the computer interlocking system or the station DMIS / CTC system. Track the shunting locomotives operating in the station, and transmit the station yard information, shunting signals in front of the locomotives, shunting routes, work orders, and shunting restrictions to the on-board host through wireless channels. The real-time display of shunting signal, shunting route and work order on the locomotive color display is realized, and the safety protection control and operation data recording of...

AI Technical Summary

Problems solved by technology

Its defect is: 1) on-site traffic conditions are inconvenient, especially the railway stations are widely distributed and remote, and technical personnel who fail can not arrive at the scene effectively in time

2) The handling level of on-site technicians is uneven. The judgment of system hardware failure requires more professional technicians who are familiar with the system structure, function, and control mode. Different failure handling personnel will affect the analysis results due to different experience and levels which in turn affects the outcome of the resolution process

Especially when safety liability accidents are involved, the real cause cannot be analyzed accurately and effectively in a timely manner

3) The operating conditions of the on-site equipment are complex, and the equipment operation record data cannot be provided to the maintenance analysts in time

4) Lack of unified analysis and statistics on the operation status of on-site equipment at each station
