Abstract: In This Design ,I Used CAN (Controller Aera Network) BUS technology。 At present ,alreadly having m3re than two thousands companies of 56 contries and sections are used CAN BUS technology very products. CAN BUS perse is one exoteric system. Using her constructing system can employ different manufactories procreative equipment and products putting up interlinkage. Simultaneity be prone to systemic extend and recompose.
Aim at designing a question for discussion is about seaurity problem of modernization floor, nerve center CMOS chip of CAN BUS networks is main core, make singlechip 80C31 for assiatant deal with information, it is one powerful function system .Currently emanaory information of manifold transducer is due to singlechip 80C31 incept and managet,then singlechip communicate CAN BUS network, make some alarm information,message, system time send to computer center awoke worker on duty notice and devise relevant measure.
Key Words: CPU、 CAN BUS network、Contorl、OSI reference mode、singlechip 80C31
