Abstract


Student class absences seriously affect the order of the university 's teaching , it will affect the quality of teaching in schools , is not conducive to the school in the student 's safety management . How to use modern means to achieve student positioning , regulating school attendance management , the problems to be solved . Student attendance has a particularity : the short time between classes , the number of people , can not access attendance ; attendance policy , does not solve the cosmetologists card phenomenon ; due to the large number of huge factors such as database , face recognition and other biometric technology means efficiency is not high. This research project is an effective solution for student attendance . The program can be realized students entering and leaving no need credit card operations , nor to set access control , thus neither students line up card affect the normal teaching order , but also help to strengthen the teaching management in the larger significance and has broad application prospects . Students positioning attendance system , including the identity collection terminal server software and the host computer is composed of two parts . This paper studies and introduce identity collection terminal design . Implementation, the distance 1 to 3M 915M range RFID RF card as an electronic tag , the identification ; collection terminal is composed mainly by the RF reader, the image acquisition unit , the information processing unit and the communication unit . Such collection terminals installed in each classroom door , RFID reader can read every students who carry electronic tags , the camera is top-loading , shooting vertically downward , will not produce the portrait shelter , accurate identification , The analysis calculations door number . The comparison of the results after the reader identify the number of image processing , whether the judgment through the door of the student body to carry multiple cards . Taking into account the special nature of a large number of student groups , does not set any access control, students can freely enter and leave the attendance register . Each terminal connected to the RS-422 communication with the host computer , send attendance data in real time . The theoretical analysis and practice show that the combination of radio frequency identification and image processing program , which can effectively judge and exclude one multi- card , no card phenomenon , effective to prevent the emergence of student cosmetologists card attendance . More accurate positioning students current position and statistics students in the campus class attendance .
