摘要
宿舍是学生群体事件易发的高危区域,为了解决宿舍区域内学生群体事件监测手段匮乏及预警滞后的难题,从学生密集程度异常可能引发群体事件和保护学生隐私的角度出发,基于毫米波传感器的人数统计功能,设计了宿舍人群密度监测系统。系统通过IWR1642毫米波传感器监测宿舍区域内的人数,当人群密度达到预警阀值后开启摄像头,并通过Wi-Fi模块将人数信息和图像信息传输至云平台。宿管人员可通过手机登录云端查看数据,并接收云端发送的报警提示信息。系统中摄像头的有条件开启可有效保护学生隐私,宿管在掌握区域内学生数量及实时图像后可及时采取措施制止群体事件的发生。本系统软硬件结构清晰,具有较好的应用价值。
Dormitory is a high risk area for student group incidents,in order to solve the problem of lack of monitoring means and lagging early warning of student group incidents in dormitory area,from the point of view that abnormal student density may lead to group incidents and protect students'privacy,based on the people counting function of millimeter wave sensor,a monitoring system of population density in dormitories is designed.The system monitors the number of people in the dormitory area through IWR 1642 millimeter wave sensor.When the crowd density reaches the warning threshold,it opens the camera and transmits the number information and image data to the cloud platform through Wi-Fi module.Managers can log on to the cloud through mobile phones to view data and receive alarm messages sent by the cloud.Conditional opening of the camera in the system can effectively protect the privacy of students,and managers can take timely measures to prevent grouping incidents after they have mastered the number of students and real-time images in the area.The software and hardware structure of the system is clear and has good application value.
