| Abstract: | The theory and technology characteristic of CAN bus are summarized,and CAN is compared with RS-485 serial communication. It is introduced the features and network structure of the synthetic automation device based on CAN technology for small hydropower station. The CPU is adopted DSP56F807,and PCA82C250 is used for CAN transceiver in hardware design,and software program as well. Presently,the device has been successfully applied in many small hydropower stations. |
