This paper design an integrated intelligent control of information transmission system of the family which uses CAN as a bus. This system uses ARM S3C2440 as the master chip, multiple CAN nodes as a data exchange module, complete the household smoke alarm, access control security and meter reading functions. Between the smoke alarm module and the CAN using ZigBee wireless data transmission. Between the module and the CAN sub-meter reading using radio frequency technology for data exchange. The whole system combines the wireless module with CAN-bus which has a flexible, intelligent, and stability advantages.
