A coal mine monitoring and control system based on dual network architecture

In view of situation of complexity of coal mine environment and a wide variety of testing nodes and parameters, a coal mine monitoring and control system based on dual network architecture was proposed. According to different monitored objects, the system uses different networks for data transmission, video streaming data uses Ethernet to transmit, mine environment monitoring data adopts CAN network to transmit. Moreover, the dual networks share the same physical line. The system has some advantages, such as the uniform testing and overall networking of all monitored objects, high network utilization and so on.
