The design is based on a CAN bus, the remote control device, through the CAN bus for control operation of field devices and other devices with the CAN bus for data transmission. Hardware of the system mainly by AT89S52 singlechip, SJA1000 CAN controller and other components, system hardware and modular software design based on single chip for the realization of the control core, designed 4 digital inputs, 4 analog output module, and the CAN interface circuit module. CAN bus applications, improve the level of intelligent building and reduce management costs of the equipment. CAN bus provides a standard network protocol for data link layer, there is no corresponding high-level communication protocol. CANopen protocol is an exoteric and standardized high layer protocol based on CAN field bus. It is a high speed serial bus system with real-time capabilities, CANopen protocol allows diffcate with each other in a standardized manner and makes them inter operable.
