Title:
TRAIN BACKUP BRAKE CONTROL SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/119497
Kind Code:
A1
Abstract:
A train backup brake control system comprises a train main reservoir pipe, a train brake pipe, an air brake control handle (10) and a relay valve (20). A conventional electrically-controlled straight brake system can be switched to the train backup brake control system at any time. Moreover, the train backup brake control system fully exploits functional characteristics of the relay valve (20) to supply a higher brake pressure to the train brake pipe, such that the entire train under control of the backup brake control system can realize brake control performance achieved by the electrically-controlled straight brake system, thereby ensuring a higher degree of safety and reliability for passengers. Also disclosed is a train backup brake control method applied in the train backup brake control system and capable of achieving the above advantageous effect.
