| 摘 要： | 该系统由多个红外监测电路和一个基于单片机的循环扫描报警电路构成。当有移动物体进入某一通道的监测范围时，红外探测器发出信号。单片机对所有通道进行循环扫描，发现信号后发出声光报警，并显示报警的通道号。该系统采用无线收发模块传输信号，因此具有体积小、结构简单、安装简便等特点，在安全防护领域中具有一定的应用价值。

| Abstract: | The system is composed of many infrared monitoring circuits and a circular scanning circuit based on single-chip microcomputer.When a moving object enters the detection range,the infrared sensor will send a signal.The single-chip microcomputer carries on the circular scanning to all channels.When the signal is discovered,the single-chip microcomputer sends out the alarm signal of sound and light,and displays channel number.Because this system uses the wireless transmit-receive module to transmit signal,so i... |
