Control method, device, equipment and medium for train operation

technical field

The invention relates to the technical field of rail transportation, and in particular, to a control method, device, equipment and medium for train operation.

Background technique

In order to correct the mileage of a train in a Communication Based Train Control System (CBTC), an axle counting system is usually deployed. The axle counting system includes axle counting points, and the line between the two axle counting points becomes the axle counting section.

ReportBlock, ARB) status. When a non-CBTC-class train passes through the axle counting section in the ARB state, or when the axle counting equipment fails, such as the falling off of the axle counting head, the Zone Controller (ZC) cannot know the situation in the axle counting section. The ZC will change the state of the axle counting section from the ARB state to the Uncommunicated Train (UT) state to prohibit subsequent trains from entering the axle counting section.
