多区域红外监控无线报警系统设计 摘 要 随着社会安全保障的需要，电子报警这门综合技术正在不断地发展。与此同时，红外技术已经成为先进科学技术的重要组成部分，用它进行红外探测监控，具有良好的隐蔽性，而且其抗干扰能力强。本设计就是利用电路控制技术和红外探测技术实现了多区域的红外监控无线报警系统。 本课题采用HN911作为红外探测模块，用VD5026/VD5027作为编/解码芯片实现四通道红外监控无线报警系统。当有物体进入检测范围时，发射机发出高频无线电调幅波，接收机收到信号后发出声、光报警。该系统主要由4个红外探测发射机和1个无线声光报警接收机组成，具有成本低、体积小、功耗低、安装简便等特点，能够为满足普通对多区域控点报警器的需求。 关键词：无线收\发模块，报警系统，VD5026\VD5027，HN91  Design of much-channel wireless alarm system based on infrared sensor Abstract As technology continues to develop, the more closely the links between systems, between the various systems of data transmission required higher and higher. With the popularization of computers, technology formed a computer-based system with some external devices. But the more external devices to connect more with the line also. As the social security needs, electronic alarm comprehensive technology is constantly evolving. At the same time, infrared technology has become an important part of advanced science and technology. As infrared detection monitoring, it has the capability of well-concealed and strong anti-jamming. This design is use of electric circuit control technology and infrared detection technology to achieve much-channel wireless alarm system based on infrared sensor. In this paper, a four-channel wireless alarm system based on infrared sensor is designed by the use of HN911 as infrared detection module and by the use of VD5026 \ VD5027 as the encoding\decoding chip. When a moving object entered the detection range, The high-frequency radio transmitter can emit AM signal. The receiver can send off the sound and light alarm. The system is mainly composed of four-channel wireless transmitter based on infrared sensor and a receiver with sound and light alarm. The system features are low cost, small size, low power consumption and easy installation. It has some value in the multi field of security in order to meet the demand of ordinary.
