Document Type and Number:
WIPO Patent Application WO/2019/119492
Kind Code:
A1
Abstract:
A method and system for alternatingly activating two control units of a train, and a train provided with control units applying the method. In the method for alternatingly activating two control units of a train, two control units are activated in an alternating manner each time a train is powered-on and started, such that the two control units are used intermittently, thereby ensuring balanced use of the control units while enabling timely detection of a failed control unit, significantly increasing service life of the control unit, reducing a probability of occurrence of a fault in a backup control unit which has not been activated for a long time, and improving safety performance of the train.
