摘　　要：为了实现对重大安全场所无线自动报警和监控,根据热释电红外传感的基本原理,设计并实现了一种接收移动人体辐射出得红外线检测仪,该检测仪以ATmega16单片机为控制中心,融合了无线通信技术[1]和信号检测技术等,通过无线收发模块与控制器通信,控制器通过RS-485与控制计算机连接,整个系统组成无线网络,实现多路无线声光报警和远程监控。另外该系统还设计了显示模块方便数据的读取分析。其设计具有实时性强,可靠性高,成本低。In order to realize the functions of wireless automatic alarm and monitoring for the major security sites, according to pyroelectric infrared sensor＇s basic principle, the author designed and realized a infrared detector which depends on receiving the infrared radiation from a moving body. The detector takes ATmegal6 microcontroller as the control center, and combines wireless communication technology and signal detection technology, and communicates with the controller by the wireless transceiver module. The controller is connected to the control computer via RS-485, and the entire system composes of a wireless network, which implements a multi-channel wireless sound and light alarm and remote monitoring. In addition, the system also designed the display module to facilitate data analysis. This system in this paper has the following advantages： good real-time, high reliability, low cost, convenient maintenance, etc.
