| Abstract: | The communication manager in transformer substation automation system assumes the tasks such as protocols conversion, mathing in- terface and collecting data. In the process of transmit data, communication interface is very important. This paper focuses on hardware and software design about CAN bus and RS232 bus communication circuit. The design utilizes ARM7 as core and exploits correspondence software in embedded development mode; adopts modular design that is convenient for examining and repair and system up grade, enhances the reliability of the system. |
