Design of Network Communication of Safety Monitoring and Control System in Coal Mine Based on CAN Bus

CAN Bus is one kind of serial communication Bus which support distributed control and real-time control effectively.In coal mine,the real-time requirement of communication of safety monitoring system is critical and each communication traffic is little,so the system is suited for CAN Bus.In this paper,a safety monitoring and control system in coal mine based on CAN Bus was introduced,the design of structure for network,parameter assignment for network,communication protocol were described in detail.
