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.

当前LCM的主流接口有并口和串口。并口引脚多，产生串扰，串口则没有诸如此类的缺点。SPI作为串口家族的一员，具有高速同步、芯片管脚少和信号稳定不产生串扰等优点，越来越受到开发人员的青睐。但是，具有SPI的LCM并不是毫无缺点的，市场上以COG(chip on glass)方式封装的LCM大都是基于单工方式传输的，这将给开发带来了非常大的麻烦。本文主要论述基于单工SPI的GUI开发方案，详细地分析了基于单工SPI的GUI的开发开台，论述并分析在GUI开发过程中遇到的问题，最后提出增加虚拟LCD的方案解决这个问题。-err
