基于单片机的防盗报警器课程设计(改良版)

基于单片机的防盗器设计（论文）

摘要

基于社会安全保障的需要，电子报警这门综合技术的正在不断的发展。与此同时，红外技术已成为先进科学技术的重要组成部分，由于红外线是不可见光，因此用它进行红外探测监控，具有良好的隐蔽性，白天和黑夜都可以使用，而且其抗干扰能力强。防盗报警系统利用单片机控制技术，自动探测发生在布防区内的侵入行为，产生报警信号，一旦发生突发事件，就会向人们发出报警提示，从而让人即使采取应对措施。本系统采用了热释电红外传感器，它的制作简单、成本低、安装比较方便，而且防盗性能比较稳定，抗干扰能力强、灵敏度高、安全可靠。这种防盗器安装隐蔽，不易被盗贼发现，同时它的信号经过单片机系统处理后方便和PC机通信，便于多用户统一管理。本设计包括硬件和软件设计两个部分。硬件部分包括单片机控制电路、红外探头电路、驱动执行报警电路、LED控制电路等部分组成。处理器采用51系列单片机AT89C51，整个系统是在系统软件控制下工作的。因此在防盗、警戒等安保装置中得到了广泛的应用。此外，在电子防盗、人体探测等领域中，热释电红外探测器也以其价格低廉、技术性能稳定等特点而受到广大用户和专业人士的欢迎。

Abstract

Based on social security needs, and electronic alarm the comprehensive development of technology are constantly. At the same time, infrared technique has become an important part of the advanced science and technology, because infrared is not visible, so use it to make the detection and monitoring of, elusive day and night to use, and its ability. anti-interference ability is strong. Burglar alarm system of control technology, automatic detection monolithic integrated circuits in the area of trespass, a warning signal, the event of unexpected incidents, will be issued a warning to people, and people to take countermeasures. The system adopted by the infrared sensors heat, production costs were low, simple and convenient installation, and the relative stability p anti-interference erformance, ability, sensitivity high and security. This is not easy to install hidden bug and found that it was the signal of a monolithic integrated circuits after handling system and pc, and facilitate unified management. The design of hardware and software design two parts. the hardware contains a monolithic integrated circuits to control circuit, infrared probes circuit, the circuit, led by the police control circuit for parts. Processor by 51 series monolithic integrated circuits at89c51, the whole system is in control system software job. Therefore, in the security and the security device of ophcal found wide application. in addition, the electronic fraud detection, the waiting area, infrared detector and heat the electric for its low price and technical performance and stability characteristics by the users and professionals.

Keywords: singlechip; infrared sensor; data collection; warning circuit
