The invention discloses a distributed network control system. The system comprises a display HMI, a master controller, two sets of slave controllers, an IO module and a CAN bus, wherein the display HMI and the master controller are arranged in a control room; the two sets of slave controllers are separately arranged in a left power box and a right power box; the IO module is arranged on a detection element or an execution system; the CAN bus is used for communication, the IO module forms a functional module through a distribution box; the functional module is in communication connection with the slave controllers through the CAN bus; and the slave controllers are in communication connection with the master controller through the CAN bus to form a bus network; the display HMI is used for displaying data and inputting instructions, and the display HMI is in communication connection with the main controller through the CAN bus; and the IO module drives the execution system to operate according to the action instruction and uploads data of the detection element to the slave controllers. According to the distributed network control system, the wiring complexity is reduced, the long line laying distance is avoided, the control cost is reduced, and module splitting and expansion are facilitated.

    本发明公开了一种分布式网络控制系统,包括设于操纵室内的显示器HMI和主控制器、分别设于左右动力箱内的2组从控制器、设置在检测元件或执行系统上的IO模块以及用于通信的CAN总线;所述IO模块通过分线盒形成功能模块,所述功能块与所述从控制器通过CAN总线通信连接、所述从控制器与主控制器通过CAN总线通信连接构成总线组网;所述显示器HMI用于显示数据和输入指令,所述显示器HMI与所述主控制器通过CAN总线通信连接;所述IO模块根据动作指令驱动执行系统运行、将检测元件的数据上传至从控制器。本发明降低布线复杂度,避免线路敷设距离长,降低控制成本,有利于模块拆分与扩展。
