1、多区域红外监控无线报警系统设计_毕业设计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

2、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，VD5026VD5027，HN91Designofmuch-channelwirelessalarmsystembasedoninfraredsensorAuthor:iTutor:AbstractAstechnologycontinuestodevelop,themorecloselythelinksbetweensystems,betweenthevarioussystems
