Motor train unit warning device based on voting mechanism

Abstract

The invention relates to a motor train unit warning device based on the voting mechanism. A basic function module of the motor train unit warning device comprises a power supply module, intelligent relay modules, DI detecting modules and shaft speed detecting modules, wherein the power supply module provides electricity for the intelligent relay modules, the DI detecting modules and the shaft speed detecting modules, the number of the power supply module is one, the number of the intelligent relay modules is two, the number of the DI detecting modules is two, the number of the shaft speed detecting modules is three, and mutual communication is achieved among all the modules through a CAN bus. Due to the fact that the motor train unit warning device is based on the voting mechanism, the redundancy detecting mechanism and the fault-tolerant mechanism, the warning device can operate normally under the condition that the modules of the warning device break down, and the phenomenon that a train is stopped due to the fact that the modules of the warning device break down is prevented.

Description

technical field [0001] The invention relates to the electrical field of railway vehicles, in particular to a vigilance device for EMUs for supervising whether the driver is competent for operation. Background technique [0002] The main function of the EMU vigilance device is to monitor whether the driver is competent for the operation, to prevent the driver from dozing off or leaving work while the train is running, and to have an automatic parking function when the driver suffers from an emergency injury or loses the ability to control the locomotive. The vigilance device detects the running speed of the train. When the train is running faster than the set speed, the driver needs to step on the pedal of the vigilance device at regular intervals. If the pedal does not move within the specified time, the vigilance device will give an alarm; If the pedal still does not move within a period of time, the vigilant device will automatically disconnect the safety circuit to make t...

AI Technical Summary

Problems solved by technology

[0006] The shortcoming of the existing EMU vigilance device is that when it detects that it has broken down, it is impossible to determine which of the detection mechanisms has broken down. , the alert device judges that its own work is invalid, and it will disconnect the safety circuit, causing emergency braking to stop

In this way, there will be parking accidents caused by the failure of its own modules
