摘 要: 为了解决目前采用有线方式的住房入侵检测系统所带来的性能不可靠、成本高、安装困难等问题,本文分 析并设计了一种基于热释电红外传感器(PIR)的住房入侵检测系统,系统采用HC-SR501红外感应模块检测入侵,通过 AT89C51单片机进行信号处理和控制,采用nRF24L01无线模块实现节点间的无线通讯。本文首先对系统进行了总体的 方案设计,然后针对系统的组成及其功能进行了相应的硬件和软件的设计。实验测试结果表明,系统具有较高的入侵检 测准确性和实时性,系统稳定性高,功耗低,安装简便,实用性强。

Abstract: The current house intrusion detection system through cable connections has some obvious disadvantages,such as unreliable performance,high cost and complicated installation.This paper analyzes and designs a house intrusion detection system based on Pyroelectric Infrared Sensor (PIR).The system applies the HC-SR501 infrared sensor module to detect instructions,uses the AT89C51 single chip microcomputer to process and control signals,employs the nRF24L01 wireless module to implement wireless communication among nodes.The paper firstly designs the overall scheme of the system,and then designs the hardware and software according to the composition and functions of the system.The experimental results show that the system has high-level accuracy and real-time capability of intrusion detection with high stability,low power consumption,simple installation and good practicability.
Keywords: infrared detection;housing instrusion detection;HC-SR501;STC89C51 MCU;nRF24L01 wireless module
