Abstract

The invention provides a train control system vehicle-mounted VOBC state machine implementation method and device. The method comprises the steps of decomposing a state event trigger signal received by a main state machine into sub-state event trigger signals under the condition of determining that the main state machine is not in a highest preset state; according to the sub-state event trigger signal, combining state switching results of different sub-state machines into a target composite state; and under the condition that the target composite state is determined to be an effective state, updating the current state of the main state machine to be the target composite state. According to the train control system vehicle-mounted VOBC state machine implementation method and device provided by the invention, multiple operation states can be completely simulated, and the complexity of the whole state switching process is simplified.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method and device for realizing a vehicle-mounted VOBC state machine of a train control system. Background technique [0002] With the rapid development of urban rail transit technology, the training of vehicle drivers is becoming more and more important. At present, the vast majority of urban rail transit training systems are Communication Based Train Control System (CBTC). As an important part of the CBTC system, the Vehicle On-Board Controller (VOBC) subsystem is responsible for completing the Automatic Train Protection (ATP) / Automatic Train Operation (ATO) functions. At present, the existing VOBC system is mainly developed in conjunction with the train scene workstation to jointly verify its performance. However, when the vast majority of VOBC systems are combined, there will be unsmooth switching of train operation levels and logical confusion in the driving mode, r...
