But in the meantime the theft of vehicles,which becomes a world wide public hazard,makes people suffer from tremendous economic loss. In foreign countries,the vehicle alarm system upgrades from the original mechanical mode to the latest SCM control–Based mode after several generations. But in China,considering the price and technology,the common electronic vehicle alarm equipments are still the dominant ones. In view oft he deficiencies of most common vehicle alarm equipments prevalent in the market, such as single alarm ability, low security and lack of tracking and monitoring ability, a vehicle alarm system based on SCM control Communication platform in this paper. Integrating the traditional vehicle alarm technology and SCM technology and according to the designing principles of SCM control system,the system builds up a mutual platform among the vehicle owner and the vehicle by using the vehicle monitor and control protocol based on GSM short message. First,use sensors to acquire any stolen information and pass its to SCM for processor.Then,SCM calculation,judgment and analysis and send text messages to the vehicle owner.The vehicle owner according to the actual condition and sent to the vehicle control directive to the vehicle by mobile phone short message,so realizing the cell phone remote control
