| Abstract: | The bus communication network based on STC12C5A60S2 microcontroller, CAN interface controller of SJA1000, and PCA82C250 serial transceiver is introduced. The CAN note on the remote side can monitor the field environment, and achieve data transceiver and serial communication. Upper PC uses monitoring interface designed by VB6.0 to achieve real-time display of CAN node environment parameter. The CAN bus nodes, networking technology are stressed. The system hardware circuit design and software processing flow are provided. The experimental results show that the system has the advantages of reliable data transmission, long distance communication, real-time display and strong anti-jamming capability. |
