- Urban rail train network control system -
The train network control system (hereinafter referred to as network control system), namely train control and management system (TCMS), takes Train communication network (TCN) as the center to realize data information exchange within the whole train, connects all train subsystems through a series of general data interfaces, and realizes all important equipment on the train, such as traction transmission unit, braking unit, signal system, auxiliary transformer unit, air conditioner, door, passenger information system The data transmission interaction and equipment status monitoring and control functions between CCTV and other equipment are the core control equipment of the train. The network control system retains the MVB or CAN bus of traditional TCMS, and adds an ECN network to achieve more and faster data transmission, improving the overall performance of the system.
The host of the network control system adopts a modular design, which is divided into CPU board, low-speed board, high-speed board, power supply (PWR) board, power input unit (PIU) board, and backplane. Low speed cards include digital input (DI) cards, digital output (DO) cards, and analog input output (AIO) cards; The high-speed board includes MVB bus communication (MVB) board, CAN bus communication (CAN) board, and serial communication (UART) board; The CPU board has an Ethernet communication module, a data recording and storage module, and a serial port debugging module; The backplane provides mutual connections for various functional boards and cards. The entire product has power failure protection function, temperature detection function, automatic card recognition function, and fault self inspection function.
