摘 要
红外线防盗报警器是当前使用比较普遍的报警器之一，它以其灵敏度高、价格实惠，受到了广大用户的欢迎。但是使用每一种红外线传感器都有其不足之处，如抗干扰能力弱、误报漏报现象严重等，可靠性不够高。目前市面上装备主要有压力触发式防盗报警器、开关电子防盗报警器和压力遮光触发式防盗报警器等各种报警器，但这几种比较常见的报警器都存在一些缺点。 本文设计的单片机STC89C52是STC公司生产的一种低功耗、高性能CMOS8位微控制器，具有 8K 在系统可编程模结构>烷基叔丁基醚Flash木制花瓶存储器。STC89C52使用经典的MCS-51内核，但做了很多的改进使得芯片具有传统51渣油加氢单片机不具备的功能。在单芯片上，拥有灵巧的8 位CPU 和在系统可编程Flash，使得STC89C52为众多嵌入式控制应用系统提供高灵活、超有效的解决方案。电路
设计包括红外热释电传感器，按键、蜂鸣器，单片机控制电路。软件设计部分包括系统主程序，红外热释电传感器子程序，报警子程序和按键子程序，均采用51系列C语言编程实现。
lrcpAbstract
Infrared anti-theft alarm is the use of more general alarm, with its high sensitivity, affordable, welcomed by the vast number of users. But the use of every kind of infrared sensor has its disadvantages, such as weak anti-interference ability, the false alarm phenomenon is serious, not high reliability. Currently available equipment main pressure triggered burglar alarm, switch electronic anti-theft alarm and pressure shading triggered burglar alarmand alarm, but these kind of quite commonalarm apparatuses all have some shortcomings.
In this paper, the design of the single chip microcomputer STC89C52 is a low power, high
performance CMOS8STC company production of micro controller with 8K in system programmable Flash memory. STC89C52 uses the classic MCS-51 kernel, but made a lot of improvements make the chip with the traditional 51 microcontrollerfeatures not available. In a single chip, 8 bit CPU dexterous and in system programmable Flash, the STC89C52 offers solutions for high flexibility, super efficient for many embedded control applications. Circuit design includes the pyroelectric infrared sensor, buttons, buzzer, MCU control circuit. The part of software design including themain program, the pyroelectric infrared sensor alarm subroutine, subroutine and the subroutine button, using 51series of C programming language.
