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.
Description
technical field [0001] The invention belongs to train network technology, in particular to a train network control system. Background technique [0002] With the continuous development of rail transit such as high-speed rail, subway, and bullet trains, it has become a trend to provide passengers with diversified information services while satisfying the safety and reliability of train operation. [0003] At present, most trains use a network control system based on a Train Communication Network (TCN for short). TCN is an international standard for train network control systems, which divides the communication network into a train-level communication network for connecting vehicles that can be dynamically organized in each section—Twisted Train Bus (hereinafter referred to as WTB) and a network for connecting The vehicle communication network of the fixed equipment in the vehicle—Multifunctional Vehicle Bus (MVB for short). [0004] However, the existing TCN network is incr...
