基才单片机的太阳能人数统计系统设计

摘要

设计了一款基于AT89S52单片机的人数统计系统，介绍了该系统的工作原理和设计方法。该系统以太阳能作为供电能源，以对射式红外组成系统检测电路，单片机对进出人数做统计，结果通过数码管显示。实验测试证明，设计的样机系统实现了人数的实时监测和显示功能，可靠性高且达到了良好的效果，可广泛用于各大高校教室、实验室管理系统以及银行、售票厅等公共场所。%A statistics system of people based on AT89S52 was designed, whose working principle and designing method were introduced. The solar energy was used to be power supply, and the photoelectric beam detectors were used as detecting circuit. The number of people in or out was counted by MCU, and then displayed by LED. The experiment shows that the number of people monitoring and displaying functions of the system are achieved and the result is very good. The system could be applied on classroom and laboratory of every university and bank or tickets room broadly.
