简单的入门例程，初学者的必看。。。。。。关于51单片机的C语言开发...

本系统主要用于旅游景点记录游客人数，并限制旅客的流量。采用红外传感器通过检测人体红外并对通过人数进行计数，通过红外对管将检测到的数据发送至单片机，单片机处理后送至数码管显示，数码管显示的数据即为通过的人数，并通过设定值限制旅客数量。当游客超量是系统将给出相应的提示，禁止游客再进入。以更好的保护旅游景点的生态环境。-This system is mainly used for tourist attractions recording the number of visitors and limit the flow of tourists. Use of infrared sensors by detecting the human body by infrared and number of people count on the tube will be detected by infrared the data sent to the MCU, MCU after treatment sent to the digital LED display, digital LED display of the data shall be the number of through and through setting limits the number of passengers. When the visitors over-the system will give the appropriate prompts to prohibit visitors from re-entering. To better protect the tourist attractions of the ecological environment.
