Title:
SWITCHING SYSTEM AND SWITCHING METHOD FOR MULTIPLE TRAIN SUPERVISION SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2024/036772
Kind Code:
A1
Abstract:
A switching system for multiple train supervision systems. The switching system is provided at each station. A redundant switching unit (2) in the switching system comprises two signal communication interface machines (201, 202), which are redundantly provided, and a redundant switching module (203), which is connected to the two signal communication interface machines (201, 202), wherein the two signal communication interface machines (201, 202) are respectively connected to a new train supervision system (3) and an existing train supervision system (4). The current signal communication interface machine in the redundant switching unit (2) in the switching system switches, according to a switching instruction sent by a control center, from the existing train supervision system (4) to the new train supervision system (3), or switches from the new train supervision system (3) to the existing train supervision system (4). Reliable switching between new and old systems is ensured, thus reducing the switching time and the switching workload. In addition, switching between simplified standby systems in an emergency is retained, thus ensuring the highly reliable operation of the entire system, and minimizing the impact on operations. Also provided is a switching method for multiple train supervision systems.
