Underground Gas Monitoring and Control System with CAN Bus Based on ARM

According to demands of gas monitoring and control system of coal mine underground on the side of real-time and reliability,the paper proposed a design scheme of underground gas monitoring and control system with CAN bus based on ARM,introduced design of hardware and software of the system and design of CAN bus interface in details.It also gave program flow of gas data collection and CAN bus communication.The experiment indicated that the system has simple structure and higher real-time and reliability.
