A method, system and train for shifting between dual control units of a train

Abstract

The invention discloses a rotation method between dual control units of a train. The rotation method alternately starts one of the dual control units each time the train is powered on, so that the dual control units are used intermittently. It can ensure balanced use and timely detect faulty control units, which significantly extends the service life of the control unit, reduces the possibility of the backup control unit failing due to being not started for a long time, and improves the safety of the train. The invention also discloses a rotation system between dual control units of a train and a train provided with a control unit applying the rotation method, which has the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of using train control units, in particular to a method, system and train for shifting between dual control units of a train. Background technique [0002] With the continuous development of our country in the field of bullet trains and high-speed rail, more and more passengers and trains are being opened, because people are pursuing more convenient, faster, more comfortable and safer travel methods. Therefore, how to target possible It is the research focus of those skilled in the art to continuously improve the existing safety hazards. [0003] For trains such as high-speed trains and bullet trains, various equipment in the train will be controlled by the train control unit. Considering that the only train control unit will fail when the various equipment in the train fails, an additional The standby train control unit, and in the prior art, only when the main control unit is abnormal, the standby control...

Problems solved by technology

[0003] For trains such as high-speed trains and bullet trains, various equipment in the train will be controlled by the train control unit. Considering that the only train control unit will fail when the various equipment in the train fails, an additional The standby train control unit, and in the prior art, only when the main control unit is abnormal, the standby control unit will be activated. Since the main control unit is abnormal and not abnormal, the standby control unit may take a long time to activate. During this period, no attention should be paid to the replacement of the spare control unit. At the same time, using the same control unit for a long time will accelerate the aging of the hardware, and the control unit that has not been used for a long time may also fail.

If the two control units cannot be activated, it may cause a series of consequences such as the cancellation of the original train travel plan and the delay of passenger travel.
