Abstract
This paper introduces the principle and design of a wireless terminal to control remote electricity,which base on SMS of GSM.The terminal consists of a wireless GSM module(Q2403 module produced by WAVECOM company) and a monitor and control unit taking single-chip microcomputer(AT89S52) as the core.Using the AT commands,the monitor and control unit can communicate with the GSM module though serial interface.The terminal let people control(shut down、switch on and restart) the remote equipments easily and conveniently by text short message of mobile phone,using GSM module Q2403.
