The design is building intelligent alarm system designed to meet the needs of robbery, theft and accident prevention. At present in the market condition equips mainly has the pressure totouch the hair style burglar alarm, the switch electron burglar alarmand the pressure shields light the hair style burglar alarmand so on each kind of alarm apparatus, but these kind of quite commonalarm apparatuses all have some shortcomings. This system used hashotly released the electricity infrared sensor, its manufacturesimple, cost low, installm the antijamming ability strong, thesensitivity high, safe was reliable. This kind of security installmenthiding, was not easily discovered by the bandits and thieves.Simultaneously its signal after monolithic integrated circuit systemprocessing the convenience and PC machine correspondence, isadvantageous for the multiuser unification management. This design designs two parts including the hardware and software. Thehardware partially including the monolithic integrated circuit controlcircuit, infrared pokes head in the electric circuit, the actuationexecution alarm circuit, the LED control circuit and so on the partialcompositions. The processor uses 51 series monolithic integratedcircuits AT89S51, the overall system is works under the systemsoftware control. The system program may divide into following severalmodules: The data acquisition, the keyboard control, reports to thepolice with the demonstration small steelyard function. Key Words: AT89S51 monolithic integrated circuit、infrared sensor,data acquisition、alarm circuit. 目录 前言 1 第一章 热释电红外
