Embodiment Construction

[0027] The locomotive safety information comprehensive detection system consists of three parts: on-board equipment, dump equipment and ground analysis equipment. According to the set conditions, it can record the various running states of the train under this condition or the state and signal when a fault occurs (or fault recording) through the on-board equipment. The recorded data information can be transferred to the computer on the ground through the dump communication interface with the dump device, and then analyzed and processed by the analysis software to obtain corresponding information.

[0028] 1. Vehicle equipment:

[0029] The vehicle-mounted equipment adopts a standard 4U high 19” wide chassis, which is mainly composed of a host template, a signal acquisition board (XHC) and a power board. figure 1 shown.

[0030] 1.1 Signal acquisition board:

[0031] The main function of the signal acquisition board is to collect train speed, brake pressure, various working ...

Abstract

The invention relates to a fault monitoring method of railway signal device and safety protection device, in particular to on-line record acquisition and off-line analysis of the track circuit signals. The invention has the following steps: collecting operation state information of train track signals, speed, super-protective brake switch amount, each working voltage, signal light state, public information and the like by an on-board device, dividing the collected information into correct information or fault information to be respectively stored in different data formats according to the different trigger conditions; unloading the recorded data to a ground analysis device by a dump device; combining the recorded data with the fixed operation line information which is input manually by utilizing a ground analysis software; and restoring the recorded data in a visual manner so as to judge fault position and reasons.

Description

technical field [0001] The invention relates to a fault monitoring method for railway signal equipment and safety protection equipment, in particular to online collection record and offline analysis of track circuit signals. Background technique [0002] The locomotive signal system, one of the three major locomotive components for railway locomotive operation guarantee, and the train safety protection system as high-speed train driving certificate have been widely used in the whole railway; but the corresponding operation monitoring and operation recording system has not been carried out. development and application. It puts a lot of pressure on the railway electrical department responsible for maintaining and ensuring the normal operation of the locomotive signal system and safety protection system; the normal operation management and maintenance work and failure analysis lack detailed operating data; the accident cannot be dynamically reproduced; accident responsibility ...
