Overview of RFID technology in school
The application of RFID(radio frequency identification) technology can realize the intelligent automation of campus access control and conference attendance and the modernization of teaching management, it is a highly centralized and comprehensive application of new network information technology and remote radio frequency identification technology. It is using remote contactless sensing, and an RFID reader automatically read tags instead of swiping cards by students. The system receives and processes these information, simply, conveniently and controllable, stably and quickly provide accurate information based on for the management of the campus. It can control the whereabouts and attendance of students, to ensure the safety and discipline management of students, to realize modern campus.
System theory
1, According to different actual needs, the system is equipped with corresponding identification cards for personnel and articles to realize real-time perception of various status and identity information. At the same time, information transceivers are installed at reasonable locations on campus to send various perceptual information to the data center.
2, Intelligent management can conduct comprehensive management and intelligent analysis of all kinds of perceived data, and according to the actual management needs to build a variety of real-time monitoring, intelligent alarm and comprehensive control and other intelligent campus management means.
3, Working principle
Combined with a low frequency locator, active RFID tag, the tag is activated after normal work. And low-frequency activator activation distance is limited, it can only in a small distance precise activation, a small scale, low-frequency activator as a basis to locate. In different locations to install different basis points, and then in a large area with 2.4 G communications recognition, reading out the signals with different ways of uploading after sending signals to the control center. Therefore, through the signal collection, the whole process of transmission, processing, and application.
4, Overview of system functions
4.1 Attendance management
Record all the teachers, students and visitors passing through the school gates in real-time. The system can also verify the identity of people entering and leaving the door to prevent illegal entry into the campus, dormitory, and other important areas. At the same time, the system can also automatically count the number of people on the campus, dormitory, and other areas, generate reports and print them out, to achieve efficient and intuitive attendance management records of students and staff.
4.2 Access Control Management
IC/ID module is built into the labeling card to realize the functions of import and export management, card consumption, and so on.
4.3 Home-school interaction
Through RFID, GPRS, etc., students’ identities and school status information can be quickly read at a distance, and students’ access to the campus, attendance, academic performance, activity notification, and other interactive information can be sent to students’ parents. The system can automatically identify abnormal situations (such as skipping class, etc.) and send prompt messages to relevant personnel.
4.4 Signing into a Meeting
Before the meeting, set the conference information, conference room, participants, and meeting documents in the system, and the system can automatically send a meeting notice. In the meeting, it can automatically record the personnel with cards in and out of the meeting, to realize the intelligent meeting attendance; After the meeting, it can send meeting minutes and handle special situations.
4.5 Statistical Analysis
It makes a STATISTICAL ANALYSIS OF all DATA, such as meetings and attendance, helps users to understand the management and operation of each work comprehensively, assists users in their daily work, and provides work efficiency.
4.6 Data Management
It provides data management functions such as information setting, modification, and adjustment for personnel, buildings, signal transceivers, identification cards, etc.
4.7 Security Management
The system provides multi-level permission control, flexibly differentiates the management rights of different users, performs different operations, and dynamically records system run logs. In the system operation, the upper level of authority has absolute priority over the next level.
4.8 Extended Functions:
4.8.1 Intelligent supervision of school buses
The school bus is equipped with special school bus intelligent monitoring equipment, bus personnel wears identification cards. Through the school bus intelligent supervision system, achieve the school bus location tracking, real-time video monitoring, bus personnel identification and intelligent management, real-time monitoring of driving conditions, and other omnidirectional school bus supervision functions.
4.8.2 Intelligent supervision of students
All students wear identification cards. Signal transceivers are installed in the school to realize the functions of students’ intelligent attendance, roll call, positioning, and tracking, and can be combined with handheld signal transceivers to realize the intelligent supervision function of students going out.
4.8.3 Intelligent supervision of the canteen
Through the intelligent identification of personnel, schools establish a sound canteen access mechanism. Distribute electronic labels for food in batches to realize food traceability management. Combined with the harmful gas sensing equipment, the concentration of harmful gases in the canteen can be detected in real-time to ensure the safety of the canteen and food.
4.8.4 Micropayment function
Users can directly use the personal card as an electronic wallet, which can be used for dining, shopping, and other consumption by swiping the card on campus. Users can also access the platform system, real-time balance query, transaction record query, password modification, and other functions.
4.8.5 Intelligent book management
The system can realize the intelligent management of the library, including the arrangement and supervision of the librarian, the intelligent identification of the identity of borrowing staff, the functions of book borrowing and returning, shelving, searching, collection inventory, and so on, and the intelligent management and positioning of the library materials and equipment.
4.8.6 Asset Management
Assets supervision
It can conduct status monitoring, tracking and positioning of assets, and view the overall distribution of assets, etc.
Intelligent warning
When the asset status is abnormal, warning treatment shall be carried out correspondingly.
Intelligent management
Provides daily information maintenance and process management functions for assets, and automatically prompts for asset planning and maintenance.
4.8.7 Perimeter protection of walls
Perimeter protection is a combination of infrared intrusion detectors, laser detectors, RFID, and other solutions to solve the problem of no effective isolation inside and outside the school. When unauthorized personnel enters the school or students climb over the wall to get out of the school, the system will automatically start the alarm and display the alarm location, and can immediately call the nearby surveillance camera, or start the sound and light alarm according to the need.
