Train multi-network integration network control system and control method

The invention discloses a train multi-network integration network control system and control method, the multi-network convergence network control system comprises a train-level network and a vehicle-level network, the two networks both use an Ethernet communication mode, and core equipment and communication networks have redundancy. The network control method comprises the following steps that: the VOBC sends a control instruction to the CCUs, the two CCUs work in a redundancy mode, the VCUs realize redundancy through two independent networks, and normal switching of redundancy is ensured by adopting a reasonable control method. The multi-network integration network control system and method have the advantages that the problem that an existing network control technology is not suitable for full-automatic train driving is solved, and the multi-network integration network control system and method are large in signal transmission data size, high in real-time performance, reasonable in redundancy and stable an
