A start-up system and start-up method for a locomotive rear main engine

Abstract

The invention discloses a start system and method for a locomotive train tail main engine. The start method includes the steps of judging whether the correspondence between the train tail main engine and a driver control device is established before start or not according to the state information, in the running process, stored by the train tail main engine before start, starting the train tail main engine in a first start mode if no correspondence is established between the train tail main engine and the driver control device before start, judging whether instant outage happens to the train tail main engine before start or not according to the time information, in the running process, stored by the train tail main engine if the correspondence is established between the train tail main engine and the driver control device, starting the train tail main engine in a second start mode if no instant outage happens to the train tail main engine before start, and starting the train tail main engine in a third start mode if instant outage happens to the train tail main engine before start. According to the method, the train tail main engine is started in different modes for different outage reasons, and the failure problem caused by the instant outage of a power supply of the train tail main engine is effectively solved.

Description

technical field [0001] The invention relates to the field of railway safety monitoring, in particular to a starting system and a starting method of a locomotive tail main engine. Background technique [0002] After the guard (car captain) of the freight train is canceled, the tail of the train is in a state of unmanned maintenance. In order to ensure the safe running and smooth braking of the train, it is necessary to monitor and control the wind pressure at the tail of the train in real time, so trains are widely used. The tail safety protection device monitors the safety of the rear of the train. [0003] At present, the train end safety protection devices widely used on railways are mainly composed of the train tail host located at the rear of the train and the driver control equipment located in the locomotive control room. The train tail host and the driver control equipment communicate through wireless communication. In order to prevent crosstalk in the communication ...

AI Technical Summary

Problems solved by technology

During the running of the train, severe vibrations often occur at the rear of the train. At this time, there may be instantaneous poor contact between the battery and the pole piece at the end of the train, which will cause an instantaneous power failure of the main engine at the end of the train, causing the main engine at the end of the train to lose control with the driver. One-to-one correspondence of devices

If this instantaneous power failure cannot be properly handled, the fault at the rear of the locomotive will not be delivered to the locomotive control room in time and cause an accident
