智能库区防盗系统的设计 作 者 指导教师 摘要：本文设计了一款以单片机为核心的智能库区防盗系统，该系统会根据不同的时间段来实现不同的功能，在白天时间段，该系统用两个红外传感器来检测人进出库区的情况，并可以统计进出人数和显示在数码管上，；在夜间时间段，系统实施夜间照明，若有人进去库区就会发出声警报，这实现了人机交互的功能。与此同时该系统具有设定和显示时间和日期的功能，相当于电子时钟，这是该系统另一个亮点。另外，系统接入了按键功能，可以设定时间、日期，可以切换显示时间、日期和进出人数功能，可以选择工作模式和休闲模式，这也是实现人机交互的重要部分。本系统可以广泛地应用其它相关领域，具有很好的可用性。本系统程序用Keil C软件进行编程及编译，再通过protues仿真软件模拟实物，实现各种具体功能的调试。 关键词： 51单片机；红外探测； 智能控制 Design of Intelligent Alarm System for Storehouse Abstract：Designed a microcontroller as the core of intelligent anti-theft system in the reservoir area, the system will be based on different time periods to achieve different functions during the day time period, the system uses two infrared sensors to detect people out of the reservoir areaand statistics out of the number and display digital tube; night lighting at night time, the implementation of the system, if people go in the reservoir area will sound alarm, the function of the human-computer interaction. At the same time that the system is set up and display the time and date functions, the equivalent of the electronic clock, which is another bright spot in the system. In addition, the system access to key functions, you can set the time, date, and you can switch the display time, date and number of people entering, you can select the operating mode and leisure patterns, and this is an important part of the human-computer interaction. The system can be widely applied in other related fields, with good usability. The system program Keil C software programming and compilation, and then through simulation kind of protues simulation software to achieve the specific features of debugging Key words： 51 MCU;Infrared detection; intelligent control 目 录 1 绪 论 1 1.1 问题的提出 1 1.2 课题研究的意义 1 2 设计任务 1 2.1 设计的主要内容 1 2.2 主要技术指标 1 3 方案论证 1 3.1 选用单片机AT89C51 1 3.2 信号采集模块探测选择 1 4 硬件电路设计 1 4.1 系统整体框图 1 4.2 人机交互硬件 1 4.2.1 数码管显示 1 4.2.2 数码管相关电路图 1 4.3 红外探测头模块 1 4.3.1 功能特性 1 4.3.2 电气及机械特性： 1 4.3.3 内部电路图 1 4.4 单片机AT89C51 1 4.4.1 AT89C51功能特性 1 4
