Abstract :
For to steals, robs and so on accidents to carry on the effective monitor and the warning, unified using the MCU AT89C51 controlling technology and the infrared detection technology, one kind of wireless burglar alarm has been designed, it including hardware and software two parts; The hardware part is composed by the infrared sensor, send and receive module ,MCU, acousto-optic warning and so on; The software part is composed of the main program and music subroutine. With C or the assembly language compilation source program, carries on the translation and the debugging in the Keilc51 platform, after downloads to the MCU AT89C51 chip, and this MCU and other primary devices welding on the PCB board according to designa circuit. On electricity, closed-cycle control switch, when some people intrude in the infrared launch area, has the acousto-optic warning, indicated that has achieved the design requirements.
