Resource management method for vehicle-vehicle communication trackside equipment based on multi-locking mechanism

Abstract

The invention discloses a resource management method for vehicle-vehicle communication trackside equipment based on multi-locking mechanism. The resource management method comprises the following steps: when vehicle-mounted equipment detects that movement authority extends to a turnout and the locking position of the turnout is matched with an operation plan of a train, sending a turnout locking command to an OC; if the turnout for the train is locked at present when the turnout locking command is locked by the OC, superposing a locking command to the existing locking state, feeding the finishing information of the locking of the turnout back to the vehicle-mounted equipment; and finally, after the finishing response of the locking of the turnout is received by the vehicle-mounted equipment, allowing the movement authority to extend across the turnout. By utilizing the multi-locking mechanism, the resources are shared by multiple vehicles, the vehicle-vehicle tight tracking is realized, the train is in a safe state when passing through the trackside equipment by virtue of sequential mutual exclusion execution strategies of an operation command and a locking command, and the resources are no longer authorized to another vehicle-mounted equipment in an operable state, so that the safety is guaranteed.

Description

technical field [0001] The invention relates to the field of rail transit technology, in particular to vehicle-to-vehicle communication technology. Background technique [0002] In the CBTC system of vehicle-to-vehicle communication, the on-board equipment needs to obtain the resources of the turnout and lock the turnout before extending its own mobile authorization to the turnout. [0003] In the current implementation scheme, generally, the OC (Object Controller, translated as the target controller or object controller in Chinese) registers the turnout resources, and the on-board equipment requisitions the turnout resources. In the existing scheme, a turnout only allows one train to lock resources. [0004] Since a switch only allows one train to perform resource locking, when two vehicles are closely following each other, only after the front vehicle releases the switch, the rear vehicle can extend the movement authorization across the switch. Under the traditional CBTC...

Problems solved by technology

Therefore, the method of one vehicle with one lock obviously cannot meet the requirements of the tracking interval of vehicle-to-vehicle communication

[0005] like figure 1 As shown, limited by the turnout, the train movement authorization cannot be extended, resulting in a decrease in vehicle speed and an increase in tracking interval
