【Abstract】 A novel electric power remote monitoring system based on CAN bus was introduced.The hardware schematics of CAN bus interface circuit for the concentrator of the system and the technique of structuring distributing-type CAN bus network were elaborated.Meanwhile the principle of CAN calling and broadcasting communication between host concentrator and slave concentrators based on double filters of CAN controller SJA1000 under PeliCAN mode were expounded.The application results show that CAN bus can realize reliable and real-time communication between host concentralor and slave ones.更多还原
