摘要
随着当前人们对家居、小区及企业等防盗防入侵需求的日益提高,安防报警系统得到广泛应用。超声波探测器、热释电红外探测器、微波探测器等这些单一技术的报警探测器都会受到环境干扰而影响探测性能,导致增加了误报率。本文介绍的热释电红外微波复合的探测器把微波和红外感应探测技术运用在一体,相互弥补了这两种感应探测技术的不足,提高了实际探测的可信度并减少了误报率。现今,手机已经成为人们随身携带的通讯工具,基于此,本项目设计了一种应用热释电红外微波复合的探测器和应用GSM模块与手机通信的基于ATmega16的低成本高效安防报警系统。
The demand of security for home, community and business etc. is currently growing. Theft and intruder alarm system has been widely used. The detection performance for ultrasonic or pyroelectric infrared or microwave detector is usually affected by interference from the environment, which increases false alarm rate. Microwave and infrared detector having dual sensing capability can made up the insufficiency of using single detector, hence increasing the alarm system reliability and reducing the false alarm rate. As mobile phone is a popular and portable communication tool for residence, the proposed alarm system is designed with using dual microwave and infrared detector and coupled with GSM technology for mobile phone communication.
