Locomotive accident isolating controlling method and device

Abstract

A locomotive failure isolation control method and a device include a failure isolation control unit and a locomotive status display screen in the driver cab. The locomotive status display screen in the driver cab is used to control a failure isolation switch in an electrical room, to parallelly or serially connect the original isolations switch circuits into a locomotive failure isolation unit circuit and control all the isolation circuits by the isolation unit. Specifically, the RS485 communication mode is adopted to send the failure isolation orders by the display screen; the locomotive failure isolation control unit receives and processes the orders, and controls a corresponding relay to action, so as to cut off the failure circuits and help the locomotive to continue to run; feedbacks the operation result into the locomotive failure isolation control unit through the hardware to show on the status screen after processing; records the operation result, for the driver to inspect and repair in the future. The failure isolation control device includes the locomotive failure isolation unit circuit and is characterized in that the isolation switch circuits are parallelly or serially connected into the locomotive failure isolation unit circuit.

Description

technical field [0001] The invention belongs to a locomotive control method and device, in particular to a locomotive fault isolation control method and structure, in particular to an electric locomotive fault isolation control method and device. Background technique [0002] During the operation of electric locomotives, it is unavoidable that sometimes some small faults will not affect the safety of the train, which are called "B" or "C" faults in the railway industry. Among them, "B" level is a general fault. This type of fault can be isolated or run with a fault without affecting the application, but it must be found and dealt with after returning to the warehouse; Processing time. Therefore, in the locomotive control system, in order to ensure that the locomotive can still operate normally after a "B" or "C" level fault occurs, a fault isolation system is generally installed in the locomotive control system. When the locomotive equipment has abnormalities and faults, t...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to: aim at the deficiency of the existing electric locomotive fault isolation system, propose a device that can use the driver's console display screen to operate commands to control the isolating switch of the electric room, and the structure is small and exquisite, which can adapt to the fault isolation of the limited space of the existing locomotive Control method and device

[0005] In view of the shortcomings of the existing electric locomotive fault isolation system, through analysis, it is found that in order to realize the current single-driver on-duty needs, it is necessary to move the operation of some equipment fault isolation switches located in the locomotive high-voltage room or mechanical room to the driver's console. Eliminate some inconveniences of a single driver on duty
