摘　　要：该计数装置以热释电红外传感器作为检测元件,以51单片机作为控制核心,进行检测和判断人体运动方向和人数统计。该计数装置结构简单,性能可靠,成本低廉,能应用在各种会场人数统计、学校教室学生人数统计、车辆乘客统计等,具有较好的应用前景。从工作原理、硬件电路、程序设计和安装调试等方面进行阐述。The counting device, with infrared pyroelectric sensor as its detection element, MCS -51 SCM as its controller, was used to detect and judge human motion and direction and statistics. The principles, hardware circuit, software design, fixing and debugging of the device were expounded. Its simple structure, reliable performance and low - cost contribute to the application in statistics in meeting places, classrooms or on buses. It takes on good prospects in the future.
