Wireless access prediction improvement method for centralized traffic control system

The invention relates to a wireless access prediction improvement method for a centralized traffic control system. The method comprises the following steps: 1, expanding an existing TD combination interface; 2, adding a related locomotive or bullet train application plan in an interface protocol; 3, adding the locomotive number attribute of the traction locomotive of the running line by the centralized dispatching system, binding the received locomotive number, train changing and hanging station and locomotive number information in the locomotive or bullet train application plan to the locomotive number attribute of the traction locomotive of the running line of the train, and marking the locomotive number attribute as a 'plan' type; and 4, matcheing the received wireless train number and locomotive number or motor train unit number information with the traction locomotive number attribute bound in the same train number operation line by the centralized dispatching system, and if matching succeeds, marking th
