Short message service ( SMS ) as a basic service of GSM work, has gained more and more attention to the system operator and developer attention, based on the short message service in a variety of applications also flourish. This system is based on GSM short message remote control system with single chip microputer ( STC12C5AXS2), as the system central controller, SIM300 module, various types of sensor module, controlled ponent such as anic bination, constitute the entire household electrical appliance control system. Through the sensor module for detecting the household appliances is used, with GSM work as a longrange signal transmission platform, so as to achieve the user through the mobile phone remote control household appliances. Data transmission is the main way of short message, the system adopted PDU model, short message receiving and transmitting through the AT instruction to implement, this paper described the mon AT instruction and its using method. Hardware design of the system, the main hardware SIM300and STC12C5AXS2SCM and its peripheral circuit were described in detail. The hardware includes munication module SIM300SIM300, STC12C5AXS2 single chip, a display unit, all kinds of sensors and data acquisition and processing unit. Software includes MCU initialization, the main program, interrupt program signal acquisition, serial munication through the short message receiving and sending program. The last part of the paper to the GSM short message remote control system as the foundation, bined with household appliances detection technology to design a set of household electrical appliance control system based on GSM, and gives the application domain of the system and some discussion and Research on the. Key words: SCM, SIM300, STC12C5AXS2. 目 錄 摘要 ................................................................
