Method and apparatus for derailment protection between adjacent wayside resource controllers, device, and medium

An apparatus for derailment protection between adjacent wayside resource controllers, wherein the apparatus comprises:

• a derailment influence source list forming module, configured to form a list of derailment influence sources by a wayside resource controller;
• a switch derailment status sending module, configured to periodically send a derailment status of switches to an adjacent wayside resource controller by the wayside resource controller according to a corresponding relationship between the switches and adjacent wayside resource control subsystems in the list of the derailment influence sources;
• a switch derailment status requesting and receiving module, configured to periodically request and receive a derailment status of the switches from the adjacent wayside resource controller by the wayside resource controller according to the corresponding relationship between the switches and the adjacent wayside resource control subsystems in the list of the derailment influence sources;
• a switch occupation permission requesting module, configured to request switch occupation permission from a corresponding adjacent wayside resource controller in the list of the derailment influence sources by the wayside resource controller when a switch authorization request from a vehicle on-board controller or a wayside train controller is received;
• an occupation permission confirming module, configured to reply to the adjacent wayside resource controller with occupation permission confirmation information by the wayside resource controller when the switch occupation permission request from the adjacent wayside resource controller is received;
• and
• an occupation authorizing module, configured to allow the wayside resource controller to authorize the vehicle on-board controller or the wayside train controller to occupy the switches when one of set conditions is met.
