大连理工大学城市学院本科生毕业设计(论文题目)基于 STC89C52 单片机的人体红外报警器的设计与制作摘 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,受到了广阔用户的欢迎。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 Flash 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 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,均采纳 51 系列 C 语言编程实现。AbstractInfrared 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 b...
