Shunting signal conversion device

Abstract

The invention provides a shunting signal conversion device. The device comprises a control module, a flat gain regulation signal acquisition module, a channel self-checking module, an automatic flat gain regulation switch module and an internal communication module. The flat gain regulation signal acquisition module collects flat gain regulation light signals and sends to the control module to read the flat gain regulation light signals after conversion, the channel self-checking module is configured to carry out self-checking on the flat gain regulation signal acquisition module, the automatic flat gain regulation switch module identifies whether a locomotive is in a shunting state or a normal running state through judging the size of the automatic flat gain regulation switch signal sent by a main computer unit of the train operation monitoring system, and the internal communication module is used for the communication between the main computer unit of the train operation monitoring system and the shunting signal conversion device, wherein the communication at least comprises sending the automatic flat gain regulation switch signal sent by the main computer unit of the train operation monitoring system to the automatic flat gain regulation switch module.

Description

technical field [0001] The invention relates to the field of trains, in particular to the field of train operation monitoring. Background technique [0002] The train operation monitoring system (hereinafter referred to as LKJ) is a train speed control device whose main purpose is to ensure the safety of train operation, and is the main guarantee equipment for several large speed increases of the railway. The existing LKJ2000 monitoring device has been developed and put into use since 2000. With the changes in the external environment such as the rapid development of railways, the existing train operation monitoring system can no longer meet the needs of train operation. Under this background, a new generation of train operation monitoring system came into being. As an important functional module of the train operation monitoring system, the function of the shunting signal interface box also needs to be further improved. [0003] The shunting signal interface box provides ...

AI Technical Summary

Problems solved by technology

[0006] First, existing interface boxes have security flaws

[0007] Since the signal of the level adjustment light display is connected to the LKJ through a combination of six signal channels, once a channel signal is connected in series, it will cause an upgrade of the level adjustment signal and affect driving safety.

[0008] In addition, the L, U, U, UU, HU, H, B and other signals of the locomotive signal are connected to the LKJ after passing through the interface box. Once the interface box fails, it may cause the LKJ to receive the wrong locomotive signal.

[0009] Second, existing interface boxes have reliability defects

[0010] When the interface box fails or the position of the transfer switch is wrong, LKJ will not be able to receive the signal of the locomotive, which will seriously affect the safety control of the trunk line

[0011] Third, existing interface boxes have drawbacks in terms of ease of use

For locomotives used for traction and small running and shunting operations, the driver needs to frequently switch the position of the switch, too much manual intervention, and poor usability

[0013] In addition, there is no detection channel inside the interface box, and its faults cannot be predicted by running files or on-board detection methods
