Namely, after OBC resource is reserved, the entering section route locking is completed, the entering section is manually handled to complete the vehicle section interlocking route locking, after the train completely enters the transfer rail, a driver confirms the degradation RM, sends a logout response to the ground OC, and then breaks the link with the OC. In the process, unlocking of the route is divided into two parts: before the vehicle-ground communication is disconnected, automatically releasing the transition rail resources of the tail clear part; and after the vehicle-ground communication is disconnected, starting a resource recovery process to recover resources so as to unlock the approach.

When the train goes out of the section, in order to prevent the route from collision, the interlocking out-section route resource which is handled to the section before the transition rail belongs to OC, and the front train route which is handled after the transition rail is positioned and the out-section route have overlapping parts, and the resources of the overlapping parts have collision.

When resources are recovered after train-ground communication is disconnected, the entering section route unlocking node in the prior art has longer resource recovery delay due to driving safety requirements, and influences train entering section efficiency. The problem of resource conflict of the outbound route can cause that the time of the outbound train entering the CBTC mode is influenced after the OBC train route handling position is pushed.
