Because of its remarkable performance, the range of application of CAN bus has already been no longer confined to the auto industry, applied to each field such as automaticallying control, automation of the building, medical apparatus extensively. Most parking areas need the lighting for a long time of a large amount of at present, adopt the traditional illumination to control, and will cause the enormous energy to waste lossing with the apparatus. This text has proposed a kind of intelligent control system of the light of distributed parking area based on CAN bus technological development. Have introduced the software of this intelligent control system, hardware design method in the article in detail. Design the on-the-spot controller based on CAN bus of content to carry on deep research, propose controlling SJA1000 as the core with the one-chip computer P89C52X2B and CAN, make up the intellectual node of CAN bus. Adopt C language to the nodal initializing and sending and receiving the module procedure and carrying on programming of intelligence, have described the software of the controller realizes the detail and some key technological problems and solutions in the course of developing in detail. This system has solved the lighting retu
