I. Demand Analysis
With the development of economy and the increase of social openness, some illegal and criminal events in the society are also affecting the school campus day by day.
The necessity of campus face recognition application system designHow to establish a safe campus environment, to protect the learning of teachers and students, the safety of campus life has been the focus of attention of the education sector and the community. Particularly important is the construction of campus security in primary and secondary schools, kindergartens, primary and secondary school teachers and students are weak security defenses, most primary and secondary school students are not yet adults, the awareness of prevention and self-protection ability is relatively weak. Primary and secondary school campus safety issues, maintaining the stability of society, touching the happiness of families, has become a topic of close attention to the whole society, directly affecting the construction of a harmonious society.
According to social surveys, a large part of the causes of safety accidents in primary and secondary schools are caused by external aggressions, including impersonal pick-ups, kidnappings and injuries from student outings, etc. The causes of these accidents can be improved and avoided by strengthening the management of student pick-ups and drop-offs, the management of people entering and leaving the school gate, and the management of people entering and leaving the dormitory.
The first is to address the hidden dangers of picking up and dropping off children in primary or kindergarten schools. At present, it may happen that outsiders take advantage of the large number of parents picking up their children to mix in the campus, and the school only recognizes the pick-up card but not the person, and the outsiders take the picked-up or stolen pick-up card to claim the children fraudulently; some are relatives or acquaintances with ulterior motives to claim the children fraudulently, and teachers do not know whether the relatives who come to claim the children have been authorized by the parents. As a result, various accidents such as kidnappings and injuries to students are caused. In order to prevent fraudulent claims, it is important to ensure that the school is able to identify that the parent picking up the child is the "real parent" or that the person picking up the child is someone authorized by the "real parent".
Most of the schools are currently adopting the method of visitor and access registration, where outsiders can enter the campus by providing false documents or reasons, and students can enter and leave the school or dormitory by manual supervision, and a few schools have adopted intelligent IC card system and other management methods, but the defect of smart card "only recognizes the card but not the person" does not bring real security management to the school. However, the defect of smart card "only recognizes the card but not the person" does not bring real security management to the school, and accidents of fraudulent use of the card to enter the campus or student dormitory often occur. To eliminate this situation, we need to ensure that the identity of the people entering the campus and dormitory is verified, and the school can grasp the identity information of the people entering and leaving in real time.
Face recognition technology has the nature of identification, identity identification can not be imitated, can well solve the above problems in the security management of schools, to create a healthy and safe campus environment for students, the application of this biometric technology is becoming a new trend of campus security construction.
II. Design Objectives
1、The face is used as the identification condition for entering and exiting the school gate and various places in the school, and the access control device refuses to pass if the identity does not match.
2. Adopt school face recognition as the identification condition for parents picking up and dropping off students. After the successful face recognition of parents, the system automatically calls out the corresponding student's information to match the parents and students. The teachers check the students and hand them over to the parents.
3、The extended system can send the face of the person who picks up the students on behalf of the parents through the Internet or telecommunication network to the registered parents for confirmation, and the system receives remote key authorization from the parents, automatically calls up the student information for matching and keeps records for inquiry.
4、It can provide the management platform of face recognition access control information, operate the database according to different authority, and provide the functions of querying access control records, data backup and data printout, etc.

3.1 System Introduction
The face recognition campus management system adopts the industry-leading face recognition technology to analyze face characteristics as the basis for identity recognition, providing a safe and convenient system solution for school access control management, dormitory passage management, and elementary school kindergarten student pickup management.
Face registration: first register the face template at the terminal.
Face detection: When a person stands in front of the terminal, the face is automatically detected and one-to-many face recognition is performed.
Button/card swipe: Input ID number in the touch keyboard or swipe card in the card reading area for one-to-one face recognition.
Face recognition: Retrieve and compare the current face with the registered face template in the database.
Access control: Identify the current person, open the electronically controlled door lock through the access control controller and allow the current person to open the door.
Local data management: face recognition terminal and management computer are connected through TCP/IP network, use browser to open access control management Web, set terminal parameters, manage user information, access control records and other data.
Remote data management: connect the face recognition terminal to the Internet through network router and other equipment, and the remote computer in the Internet can also set the terminal parameters and manage the user data, access control records and other data.
3.2 Scene application
3.2.1 School access control application
Face recognition access control terminals are installed in the pedestrian passages of each school gate, which are connected to electric locks to control the opening and closing of the pedestrian passage doors. All teachers, students and staff in the school must register their faces and face recognition must be performed when entering the school, and only after successful face recognition can the door be opened to enter the school.
For schools with closed management, face recognition access control terminals are installed on the inside of each school gate, and only teachers or staff members have access to this access control terminal during the week. Schools that allow students to go in and out freely on weekends or holidays can set up all the door opening privileges for the door identification terminal on holidays or Sundays.
3.2.2 School dormitory management application
Face recognition terminal is installed in each dormitory building, and it can also be installed in floors and dormitories according to the actual application requirements. Students entering the dormitory building must be verified by face recognition, and the door can be opened only after successful face recognition. Students visiting each other in the dormitory can be authorized by temporary face recognition at the dormitory building management office with their documents, and the temporary face recognition expires after successful verification once, so that students can only enter and leave freely in the building where their dormitory is located and ensure the safety of the student dormitory.
The face recognition management system of the dormitory building has a simple attendance function, which can record and count the face recognition data, and according to the face recognition record, the information such as the entry time of a certain student can be inquired, which is convenient for the accommodation management of the school. It is also possible to set the time period for opening the door of the face recognition dormitory management system, and not to allow access to the dormitory building during non-bedtime.
3.2.3 Student parent identity verification application
For elementary school or kindergartens, students are generally picked up and sent home by their parents after school. After school, teachers responsible for sending students are equipped with face recognition identification wireless terminals to verify the identity of parents who come to pick up students, and after successful face recognition, the wireless terminal retrieves the information of students corresponding to the parents, and teachers check whether the information matches with the pictures, and hand over the corresponding students to parents after accuracy, and if the recognition is not successful If the recognition is not successful, the wireless terminal sends an alarm signal to the school security department to notify the management personnel to verify the processing.
The face recognition parent identification system can bind a student to more than one parent for registration, or a parent to more than one student for registration, and after successful face recognition the system will transfer the corresponding student, and the parent can only pick up and drop off the student bound to him/her. If a parent who has been bound to register temporarily assigns someone else to pick up their child because of something, the teacher uses the verification terminal to take a photo of the face of the temporary pick-up person, and the system sends the photo of the person's face to the parent through the system or the Internet, and after the parent checks the photo to confirm that it is the person he or she assigned, he or she authorizes the school's face recognition system remotely through SMS or face recognition computer software, and the verification terminal pulls out the corresponding student The teacher verifies the information and delivers the student. If parents find that the person who comes to pick up their children is not their assigned person, they can send information remotely through SMS or face recognition computer software, and the school's face recognition system will alert the security department to handle the situation accordingly to prevent the occurrence of fraudulent students.
3.2.4 Application of student truancy prevention system
For colleges and universities, students' truancy is a headache for teachers. Due to the special way of students' classes in colleges and universities, the traditional roster counting method is useless and cannot effectively prevent students' truancy behavior. Face recognition technology can solve this problem by registering students' faces to the system template library, and the system can be set according to the class attendance time. Before the normal class starts, teachers start the face recognition roll-call system through the software platform, and the system will automatically count the current class attendance situation and display it in a report or graphical interface, so that students' attendance situation is clear at a glance, and face recognition can eliminate Face recognition can prevent the occurrence of substitution.
The system can also be set to real-time detection mode, which detects and identifies faces cyclically during class time to prevent students from leaving the class in the middle of class. The real-time detection mode can also be used to prevent students from not paying attention to lectures during class. When students' faces leave their seats or doze off with their heads down, the system reacts to the software platform through the management platform so that teachers can remind them in time, or the system directly outputs signals to the voice and other systems for automatic prompting. Through the setting of face recognition threshold and recognition rules, the normal small range of face movement when students listen to lectures does not trigger the system detection prompt.
