I. Overview
The application of RFID (radio frequency identification) technology to realize the intelligent automation of campus access control and the modernization of education level and infrastructure, a highly concentrated and comprehensive application of new network information technology and long-distance radio frequency identification technology, this is a predictability system. Using long-distance non-contact sensing, so that students do not need to swipe their cards, RFID readers will automatically read tags, and the system will automatically accept and process the information. It is simple, convenient and controllable, stable and fast, and timely feedback information with parents, for the campus Management provides accurate information on which to base. Control the whereabouts and attendance of students, ensure the safety and discipline management of students, and truly realize the modern campus of informationization.
2. Project background
School safety and discipline management is a topic of great concern to every teacher, student, parent, and society as a whole, especially for students in primary, secondary, and kindergartens due to their young age and poor life independence. Parents and teachers are responsible for their children’s personal safety and I am worried about my mental health. The level of school education and infrastructure is an important part of the entire society. It is related to the healthy growth of thousands of students, the happiness and stability of thousands of families, and the future of the nation and the world. Strengthening the safety management of the campus is a top priority. There are still various problems in the current campus access control system. Traditional manual guards or system management using contact or non-contact IC cards as the identification. But there are still many problems, many hidden dangers and unscientific management. For example, parents and teachers cannot learn student information in a timely and effective manner, and campus management is also inefficient, wasting a lot of manpower and material resources, and it has not yet achieved a satisfactory effect.
Three, the system process
Set up an RFID reader at the school gate to issue tags to each student. RFID tags can be placed in the student cards worn by the students. The tags contain all the student’s information. Each tag has a unique ID. Students come and go every day. In schools, the card reader at the door can read tags from a long distance and transfer them to the database. The system will send text messages to the parents of the students according to the settings, and transmit the information to the parents at any time, such as: “When does your child arrive/leave? “School”, the system can transmit information through text messages or in the form of mailboxes. It is not only the school’s entry and exit information, but also the student’s test scores, notifications of various activities, and recent children’s performance. The school can be selective Send student and school-related information so that student information can be fed back to parents in a timely manner. The school can also carry out effective and targeted management of these data and information, and make predictable and feasible reforms and innovations in school management , Rich scalability, provides the most basic guarantee for the construction of informationized campus, thereby improving the level of information management of the entire school.
Four, system function
1. Information writing of RFID tags
Write the data information you want to write to the blank RFID radio frequency identification card; each student’s tag card has a unique identification ID, RFID reads all kinds of data information currently stored in the radio frequency identification card, including student name and class , Teacher, home address and other information, you can also easily modify or (rewrite) the data information in the RFID card.
2. RFID reader complies with multiple protocols
RFID reader supports seamless network integration, real-time reading and writing of all EPC-compliant tags, multi-protocol wireless identification readers, obtaining information quickly and accurately, and providing visibility control while obtaining information, with rich scalability Flexibility, and can be expanded flexibly as the system changes
3. RFID automatic long-distance recognition
The reader at the school gate can read the RFID tag in the student’s student card at a long distance during and after school. The reading distance is predictable at about 20 meters, and the reading speed can reach 80 kilometers/ It can identify 1,000 inductive RFID tags per hour, eliminating the need for traditional manual guarding students to show or swipe their cards. In this way, omissions and inefficiencies are unavoidable, which will also arouse students’ disgust. Using a variety of RFID identification can quickly read the tags worn by students, dozens of students pass at the same time, can be accurately and quickly identified, which improves accuracy and efficiency.
4. Identify the direction
The RFID reader has the function of distinguishing direction, ensuring that the system can accurately identify whether a student comes to school or leaves school, which improves the integrity of the entire system and is more intelligent.
5. Effective and timely information communication
Through the SMS service platform, students’ information can always be sent to parents via SMS, so that parents can accurately know the child’s arrival and departure time, determine the safety of the student on the road, and the status of the student at school. Such as attendance and absence from school, to avoid unnecessary disputes between parents and the school. It also provides a legal basis for the guarantee of the rights of both the school and the parents of the students, making it open, transparent, and more fair and reasonable. The most important thing is that the school and the family have a symmetry of information, convenient and quick information communication, so that educators and students’ parents can better cooperate with each other, and improve the quality of education as a whole. Schools can also use the system to implement internal management, such as the attendance system for teachers and students, and the system automatically generates attendance reports on a monthly basis based on accumulated data. The relevant education department can also understand the situation of each school in real time and facilitate the evaluation of the school. The level of attendance.
6, can be inquired in time
The system is a B/S architecture. Any computer connected to the Internet can be viewed and managed. Each department of the school can set corresponding access and management permissions. Related departments such as the principal’s office, security office, class teacher, etc. can log in according to their permissions. , Can view the information within the authority and can print related information.
7. Value-added services
The school can sell the naming rights of the student card to nearby businesses. The best businesses are stationery stores, bookstores, and supermarkets. These businesses are closely related to the lives of students, but they must be advertisements that are helpful to students’ lives and bring them to students. convenient. This kind of advertising investment by businesses will also be very effective. The campus will obtain advertising costs from it, reducing the overall cost of ownership of schools and students, and allowing schools and students to reduce input costs.
8. Reduce the total cost of ownership
The RFID tag card reduces the price to the lowest possible level. It can be collected as a deposit, and the student can be refunded after graduation or transfer. The RFID tag card has fine workmanship, is not easy to be damaged, and can be used for a long time. Students only need to pay some low-cost text messages every month. The one-time investment is large, and there is little workload in the later stage. Compared with other systems in the later period of maintenance and workload, it has obvious advantages. This system has advanced technology and centralized management, which improves the informationization of the campus to a higher level and reduces the total cost of ownership of the school as a whole.
