Description

A multi-standard interface configuration method for the boundary buffer of a regional controller

technical field

The invention relates to a multi-mode interface configuration method for a boundary buffer area of a regional controller.

Background technique

With the continuous maturity of automatic driving of rail transit, fully automatic driving of trains has been applied to more and more projects, which has improved the operation capacity of the line to a certain extent, and also put forward higher requirements for the train control system. The zone controller in the train control system needs to be able to ensure that the train passes the boundary quickly and accurately at the boundary of the zone controller to ensure driving safety. If there is a train envelope at the border that is not associated with a train ID or a train running in the manual driving RM mode, the regional controller needs to activate a certain buffer zone according to the train envelope to limit the movement authorization endpoints of the train before and after the current train envelope to ensure Train driving is safe. The buffer zone should consider the state of the switch ahead of the train. When the state of the switch does not match the state of the switch in the buffer zone, the corresponding buffer zone does not need to be activated. The current regional controller buffer configuration method can only support one interface standard, and cannot flexibly deal with different interface standards.

The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.
