This design designs two parts including the hardware and software.The hardware partially including the monolithic integrated circuit,infrared pokes head in the electric circuit,the actuation execution alarm circuit，the LED control circuit,the waireless transceiver circuit and so on the partial compositions.The processor uses 51series monolithic integrated circuits AT89C51，the overall system is works under the system software control.The system program may divide into following several module
