Node Design of Alarming System for Coal Gas Based on AT89C55WD and CAN Bus
According to the performance and features of AT89C55WD and CAN bus, a nod design method of alarming system for coal gas based on AT89C55WD and CAN bus is proposed in this paper. The hardware structure and the design process of software are discussed in detail. The hardware system consists of microprocessor AT89C55WD, CAN controller SJA1000 and CAN transceiver PCA82C250. Under the support of corresponding software, the gas density, temperature and humidity can be effectively monitored by this alarming system.
