Network control device and train network control system

Abstract

The invention provides network control equipment and a train network control system. The network control equipment is composed of a CPU mainboard, a power supply and an MVB board card. The power supply is connected with a CPU and supplies power to the CPU, the CPU is connected with the MVB board card, the CPU comprises a CCU and a TCN unit, data of the CCU and data of the TCN unit are stored in the memory, and the equipment ports comprise ports corresponding to the CCU and ports corresponding to the TCN unit. An original CCU and an orginal TCN unit are integrated together. According to the invention, the CCU is connected with the TCN unit to form new network control equipment, and the communication between the CCU and the TCN unit does not need MVB anymore, so that the problems that a communication line between equipment is easily interfered and a communication cable is likely to be disconnected and short-circuited in the prior art are solved, and the judgment and control accuracy of anetwork control system on vehicle conditions is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of train control, in particular to a network control device and a train network control system. Background technique [0002] At present, the share of domestically produced locomotives and bullet trains is gradually increasing, and more and more attention has been paid to the development and manufacture of train control systems. [0003] Existing locomotives and some EMUs are mostly equipped with separate train communication network (Train Communication Network, TCN) gateway and central control unit (central control unit, CCU). figure 1 It is a schematic diagram of MVB communication for separate devices, such as figure 1 As shown, the CCU and the TCN gateway are composed of their own power supplies, CPU boards, and multifunction vehicle bus (Multifunction Vehicle Bus, MVB) boards, and are two independent devices. MVB connections enable communication. [0004] However, the independence betw...
