TRAIN NETWORK CONTROL SYSTEM

摘要

Provided is a train network control system, comprising: a main control unit and a network control sub-system corresponding to each railway car; each network control sub-system comprises an ETBN and Ethernet interface gateway; the Ethernet interface gateway is connected to the ETBN via a first Ethernet interface; the Ethernet interface gateway is connected to a railway car-mounted device on a railway car via a device network interface; the neighboring network control sub-systems are connected via the neighboring ETBNs; the neighboring ETBNs are connected via a second Ethernet interface; the main control unit is connected, via the first Ethernet interface, to the ETBN in the network control sub-system where the main control unit exists, acquires the operation status information of a train via the ETBN in each network control sub-system, and transmits a control signal according to the operation status information. The train control system is constructed as an Ethernet-based network architecture, thus increasing the transmission rate and bandwidth of the network control system.
