Switch controller is a necessary part in the connection port of intelligent switch device with secondary protected equipment and measure/control equipment. An implementation scheme of intelligent switch controller based on CAN bus and ARM kernel is proposed in this paper to meet the need for intelligent switch in intelligent transformer substation. The hardware circuit between ARM microcontroller and CAN controller is given, the way to implementing data communication among hardware ports is described, and the design cycle of the software for data communication is presented. Engineering application verifies the proposed intelligent switch controller.
