Title:
SWITCH CONTROL METHOD, DEVICE AND CONTROLLER
Document Type and Number:
WIPO Patent Application WO/2018/040295
Kind Code:
A1
Abstract:
A switch control method, device and controller, the method includes the following steps: an on-board device acquiring a switch state and determining a target resource permission to be requested according to the switch state, the on-board device sending a first resource request including the target resource permission to a switch, obtaining a resource state of the switch, and assigning a resource permission on the switch according to the resource state and the target resource permission, and controlling the switch according to a result of the resource permission assignment. The traditional interlocking technique is not used anymore, leading to simplification of the control logic and reduction of the equipment cost and the maintenance cost. Before a train arrives at the required switch and section resources, the resources are requested and assigned, thus allowing safety protection on the train and an increase in the utilization rate of line resources.
