摘　　要：研究了一种应用于课室在座人数实时监测的分布式自动化系统。该系统通过在课室安装一个以STC89C52单片机和YL-62红外线传感器为核心的人数进出信息反馈和处理模块,进行编码后经过CC1101无线数据发射模块将信息发送至连接PC机串口终端的接收模块,利用PC机进行解码和运算处理并最终显示在VB程序界面,从而达到远程监测与查询课室人数的目的。该系统结构简单,成本低廉,性能可靠,具有较大的应用前景。A kind of distributed automatic system applied to real-time monitoring for classroom population is researched in this paper. The information of population is feedback and processed by a STC89C52 single-chip microcomputer and YL-62 infrared sensor module,which is installed in classroom. By using the CC1101 wire-less data transmitter module,the coded information is sent to the receiver module connected to the serial termi-nal of PC. The information sent to the PC is decoded and computed. Finally it is displayed on the VB program interface. This achieves the aim of remote-monitoring and inquiry for classroom population. Our system is sim-ple,low cost and high reliability. It may have a great application prospect.
