| Abstract: |
| A substation monitoring system based on C8051F043 is designed，which is comprised of smart node，main controller and console work station. The design of communication module adopts CAN（Controller Area Network） bus as the communication mode. For hardware，its circuit is presented with examples and the solutions for possible conflict and interference among CAN controllers are given. For software，the design flowchart of node development，the setting of bit timer register for different baud rates，the key codes of receiving and sending modes are given and the suspended state of CAN controller after initialization is analyzed. Trial operation indicates that the communication module runs reliably，meeting the requirements of substation monitoring. |
