摘　　要：针对校园内有效自习室寻找时间过长、餐厅就餐人员密集等待时间长的现象,设计了一种适应校园多场景的人员密度监测系统~([1])。该系统以STC89C51单片机为核心,通过判断人员是否在红外传感器的感应距离范围内实现人员进出状态的检测,采用数码管实时显示局部空间的人员密度,利用LED灯及预编的程序完成空间人员超阈值报警,并通过ESP8266Wi-Fi无线传输模块将各空间人员密度进行传输并集中展示在人员密集区域,以便大家能及时掌握各空间人员密度。将此系统应用于新疆某大学自习室,结果证明系统具有可靠性高,可用性强的特点,能够实现校园多场景的人员密度监测及报警。A personnel density monitoring system adaptable to various scenarios on campus has been designed to address the issues of prolonged waiting times for finding available study rooms and crowded dining areas.The system is built around the STC89C51 microcontroller,which detects the entry and exit status of individuals by sensing their presence within the range of the infrared sensors.The system utilizes a digital display to provide real-time visualization of the personnel density in specific areas.It also incorporates LED lights and pre-programmed algorithms to trigger alerts when the density exceeds a predefined threshold.The ESP8266 Wi-Fi module is employed to transmit and consolidate the personnel density data,which is then displayed in the crowded areas for everyone to stay informed in a timely manner.The system has been successfully implemented in a university study room in Xinjiang,China.The results demonstrates its high reliability and usability in monitoring and alerting personnel density across multiple scenarios on campus.
