基于红外检测技术的防盗报警器设计
应用电子技术教育专业黄启发
[摘要]随着社会的不断发展,人们对室内财产的安全要求也越来越高,而比较普遍的防盗措施是安装防盗报警装置,因此防盗报警装置的灵敏度和可靠性是非常重要的。本设计以当前被动式红外检测技术为基础,利用具有高灵敏度和良好的抗干扰能力的热释电红外传感器构成防盗报警器的信息采集单元,再辅以机械传动装置,间歇性地带动探头在一定角度范围内往返扫描,弥补了热释电红外传感器无法检测静止的人体或者动物体的缺陷,增大了报警器的监控范围,提高了它的性能。经过硬件制作调试,本设计的有效监控范围达到200º,检测距离达到7±1米。得到了较高的灵敏度和准确度。

Design of Theft-proof Alarm Based on Infrared Detection Technology
Application of Electronic Technology Education HUANG Qi-fa
Abstract:With the development of society, people are paying more attention to their indoor property security. In this case, installing an anti-theft alarm devices in a room is the prevalent measure to meet people's need .So sensitivity and reliability of anti-theft alarm device are very important. This design is based on he current passive infrared detection technology. With it's high sensitivity and a good anti-disturbance capacity the author designed a burglar alarm of information collection unit by pyroelectric infrared probe, supplemented by mechanical transmission, intermittent led the probe scan within an angle, made up the defects of pyroelectric infrared detection probe can not scan static or animal body and increase the scope of alarm monitoring, improved its performance. After missioning of hardware, detection range of the design is up to 200º, detecting distance to 7 ± 1m. Have got high sensitivity and accuracy.
