ABSTRACT
With many years development of mobile telecommunication technology,the technology is quite mature. It integrates mobile communication, networking, digit signaling processing, automation control and micro-control technology and so on,it can widely use in many phases, for example, mobile phone telecommunicate to control robot, automobile and door guard against theft, and telecommunicate to control industry machine for operating normally.
This thesis introduces the principle and simple design of a wireless remote monitor and control terminal base on SMS of GSM. TC35 control unit taking single-chip microcomputer (AT89C51) as the core. Using the AT commands, the monitor and control unit can communicate with the GSM module TC35 though serial interface.
The thesis discusses system hardware implement scheme and character of key hardware circus firstly, then the software implement and function.
