Title:
MANAGEMENT METHOD AND SYSTEM FOR TEMPORARY SPEED LIMIT OF TRAIN
Document Type and Number:
WIPO Patent Application WO/2022/142495
Kind Code:
A1
Abstract:
A management method for temporary speed limit of a train, in which a unified session management framework is used to manage temporary speed limit instructions, and in a session closed stage, the temporary speed limit instructions in a session are uniformly processed, thereby ensuring that the temporary speed limiting instructions across zone controllers take effect consistently, and avoiding the disturbance of a system in processing the temporary speed limit instructions. The availability detection of communication links improves the availability and fault tolerance of the system in processing the temporary speed limit instructions. By adding a timeliness mechanism of messages, the life cycle management is performed on the temporary speed limit instructions, thereby ensuring the safe running of a train when a system component fails, and improving the availability of the system. Also provided are a temporary speed limit management system for a train, an automatic monitoring system for a train, a data storage unit and a zone controller.
