基于单片机的写字楼红外报警器
随着社会的发展和时代的进步，越来越多的单片机技术和传感器的技术，应
用到了人们的生产生活中。在人们的生产生活中，写字楼红外报警器也有了长
足的发展，并产生了很多的系统。
本系统进行设计了一 个基于单片机 的写字楼红外 报警器，本设 计是以
STC89C51 单片机作为系统的核心，设计了按键主动报警和热释红外自动报警，
用户可以通过按键来进行主动的报警，或者是系统处于监控状态进行巡查报警。
自动报警模式下，当热释红外感应到有人接近时，则进行蜂鸣器的报警，以提
醒用户。
关键词： 单片机  按键  热释红外 蜂鸣器

Design of Household Anti-theft Alarm System Based on C51

Single Chip Microcomputer

Abstract ：With the development of society and the progress of the times, more

and more single-chip technology and sensor technology have been applied to people's

production and life. In people's production and life, the home anti-theft alarm system

has also made great progress, and produced a lot of systems.

This system designs a household anti-theft alarm system based on C51 single-

chip computer. This design takes STC89C51 single-chip computer as the core of the

system. It designs the key-press active alarm and pyroelectric infrared automatic

alarm. Users can actively alarm through the key-press, or the system is in the

monitoring state for patrol alarm. In the automatic alarm mode, when the pyroelectric

infrared senses someone approaching, the buzzer alarms to remind users.

Key words: MCU; Key; Pyroluminous Infrared; Buzzer
