Abstract

A train master control system comprises a first main control board and a second main control board which are redundant to each other. After the first main control board is powered on and enters a CPUnormal starting state, the first main control board is configured to judge whether second main control board state information sent by the second main control board is received within a first preset duration or not, and if the second main control board state information is received, the first main control board enters a comparison state; and in the comparison state, when no error exists in the second main control board state information, the first main control board is configured to compare the state of the first main control board with the state of the second main control board according to the second main control board state information and enter a master switching state or a slave switching state according to the comparison result. According to the system, the master-slave states of thetwo main control boards in the main control system are switched by providing an ordered and stable state machine switching mode. The two main control boards compete and switch between the master device and the slave device by monitoring the states of the main control boards and the states of the other main control boards, wrong switching and frequent switching can be effectively avoided, and therefore the reliability of the system is improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a train master control system. Background technique [0002] The train communication network is known as the "brain" and "nerve" of the train. It is mainly used for data transmission such as train control, status monitoring, fault diagnosis, maintenance, on-board information service, video monitoring, and safety sensing. An important system for rail transit service quality. [0003] In related application projects, the IO boards in the network platform chassis interact with the CPU main control board through the backplane bus. The CPU main control board is the main device of the system, which collects, analyzes and processes IO data and sends control commands. Once the main control board fails, the entire system will be paralyzed, so very high reliability is required, and two main control boards can be used for single-board redundancy. However, the switching mechanism of ...
