COUPLED TRAIN AND AIR COMPRESSOR START-STOP CONTROL METHOD AND SYSTEM THEREFOR

Title:

COUPLED TRAIN AND AIR COMPRESSOR START-STOP CONTROL METHOD AND SYSTEM THEREFOR

Document Type and Number:

WIPO Patent Application WO/2023/179054

Kind Code:

A1

Abstract:

A coupled train air compressor start-stop control method. A TCMS controls the start-stop of each air compressor; and, when the accumulated working time of each air compressor exceeds a second time threshold value and the total air pressure of the coupled train reaches a set value, the air compressors are stopped. The TCMS continuously monitors the total air pressure of the coupled train. When the total air pressure of the coupled train decreases to be lower than a second set value, the TCMS controls all the air compressors on the coupled train to simultaneously start to deliver compressed air so as to ensure that the total air pressure of the coupled train is kept within a pressure range capable of ensuring the normal operation of the coupled train. The working time of each air compressor can be relatively balanced, so that an excessively long working time of a certain air compressor is prevented, and meanwhile, it is ensured that each air compressor can work for a set time, thus ensuring that air compressor oil can reach a certain temperature so as to prevent emulsification of the air compressor oil. Also disclosed are a coupled train air compressor start-stop control system and a coupled train.
