Invigilation Event Detection Leveraging On Multiple Channel Identity Authentication Mechanism

With the development of education,the scale of students is expanding day by day,and various kinds of examinations are also increasing,which makes the workload of invigilation increasing.In order to maintain the authority of the examination and the fairness of talent selection,the society has invested a lot of manpower and resources every year to improve the facilities and to train the invigilators.Although it has been able to confirm the identity of examinees by reading second-generation ID cards,identifying fingerprints and faces,verifying finger veins,and pasting barcodes,most of the other invigilation jobs are still done manually,and the cost of human resources is high.In addition,there is a problem that manual invigilation cannot directly share invigilation data with other systems,and it is difficult for invigilators to maintain attention and enthusiasm for a long time.This paper aims at introducing embedded information collection device and mobile robot into the examination room,and realizing the invigilation event detection scheme leveraging on multiple channel identity authentication mechanism with the cooperation of remote server.Make up for the shortcomings in the current manual invigilation,improve the efficiency and accuracy of examinees' identification,and enhance the invigilation effect.To a certain extent,it saves the cost of manpower and resources of invigilation and improves the level of invigilation intelligence.The specific work is as follows:1)Invigilation event detection scheme and process design.According to the necessary link of manual invigilation at present,this paper presents an automatic invigilation event detection scheme which combines embedded fixed bit information collection device,remote server and mobile robot.The detection process is divided into the examination preparation stage examinees' personal information collection and the examination ongoing stage examinees' behavior monitoring,invigilation event response etc.It realizes process oriented information collection of examinees,unified identity verification and data storage by remote servers,timely warning of abnormal conditions and dispatching instructions of mobile robots.2)Invigilation event detect in examination preparation stage.An embedded fixed bit information collection device is designed to realize the functions of identity card reading,examination pass information collecting,examinees' photo collecting and uploading,and the face contrast interface is used to realize the surrogate examinees detection in the examination.Touch screen displays sensor data and early warning information of invigilation events,completes human-computer interaction through touch control,and achieves collaboration with remote servers and mobile robots.3)Invigilation event detection in examination ongoing stage.This paper proposes to use a label in the form of QR code for examination materials,which can bind to the identity information of examinees and facilitate the acquisition of scores and the change of examination materials with the help of fixed-bit device.The basic functions of mobile robots are designed.The movement control module adds the PID algorithm to increase the accuracy and stability of the robot movement,and enable the function of examination materials giving out and collecting.The communication functions are expanded to enhance the communication compatibility between ROS system and non-ROS system.Audio and video functions are added to mobile robots.Video acquisition module records invigilation events in the process of detection,and voice broadcast function realizes prompting and warning.
