1. System overview
The campus has always been regarded as sacred and inviolable, and relatively safe in terms of the social environment, but at the same time, the campus is the easiest place to become a dangerous area. In recent years, whether it is abroad or at home, campus security incidents have frequently broken out. Whether it is theft, shooting or violence, it is related to the loopholes in the campus security inspection system. To do a good job in campus security, the first thing is to keep the “school gate” well, and the identity of the people entering and exiting must be determined, but relying on the traditional security inspection method one by one is obviously very inefficient. The new era calls for the popularization of new technologies. As one of the most advanced technologies nowadays, RFID technology has become more and more obvious in terms of personnel management, attendance, and positioning control.
2. System composition and characteristics
2.1 System composition
The campus personnel management and positioning system is mainly to complete the management and supervision of all personnel within the campus, as long as the system software is used to analyze the actual situation on the spot, and finally the final action decision is made based on the analysis results.
2.1.1. The system composition is as follows:
Electronic tags: 2.45G long-distance active electronic tags, simple and convenient to use, only need to be worn on teachers, students, school staff and other personnel;
2.45G card reader: dedicated to communication with 2.45G electronic tags, easy to install, the specific installation method needs to be determined according to the actual situation on site;
Repeater: extend the transmission distance (optional);
Controller: control card reader, one controller can control multiple card readers;
Backstage management system: the management software specially designed by the computer and the system.
2.1.2. The simple schematic diagram of the system is as follows:

High anti-interference, no special requirements for the perimeter environment, strong environmental adaptability, minimized device failure rate, and reliable operation;
Active electronic tags are used, no electromagnetic pollution, maintenance-free, and safe to use. The active identification card has a built-in battery, ultra-low power consumption, no external power supply, no need to charge;
Integrated wireless monitoring structure design, convenient and quick installation.
3. The working principle of the system and the realized functions
3.1, the working principle of the system
The schematic diagram is as follows:
Figure 2 System schematic diagram
First of all, place a number of active card readers in the places where all personnel may pass or stay on the campus. The specific number and location need to be determined according to the actual working conditions of the site and the functional requirements to be realized, and they are wired and connected through the network. The computer network of the monitoring center. At the same time, a 2.45G active electronic tag is worn on each teacher, student and other personnel. When the school personnel enter the campus area, as long as they pass or approach any 2.45G card reader placed on the campus, the card reader will immediately The signal is sensed and uploaded to the computer in the control center at the same time, the computer can immediately determine the specific information (such as: personnel name, location, time of appearance, etc.), and display it on the large screen of the control center or computer display at the same time Make a backup on the screen. The administrator can also click on a certain location in the campus area according to the distribution diagram on the big screen or on the computer, and the computer will then count and display the personnel in this area. At the same time, the computer of the control center can also sort out various attendance reports (such as late/early leaving records, non-attendance time, etc.) during this period of time based on the information of the personnel entering and leaving the school gate during the period of school and end of school.
3.2, system function
School personnel management, positioning system, management of attendance and location of teachers and students who go to school, school entrance and exit, and location, and have functions such as selection tracking and query.
Attendance function: real-time statistics of the names, times, positions, numbers, etc. of personnel entering and exiting the school, and timely statistics of personnel classes, late arrivals, and early leaving information, etc.; statistics, query, summary, report generation, printing, etc. of attendance data;
Tracking function: real-time dynamic tracking of campus personnel, position display, running track playback, real-time dynamic query of the distribution of campus personnel in a certain area at a certain time, and real-time positioning and tracking of special personnel;
Query function: you can query all personnel on campus (such as: personnel name, current location, etc.);
Modification function: the relevant personnel information can be modified to reflect the latest personnel situation;
Delete function: delete the information of graduated personnel.
Networking function: The system has a powerful networking function. According to user needs, the control center and each system can be networked in a local area network, so that all networked systems can share attendance tracking data within the scope of use authority, which is convenient for remote query and management ；
Expansion function: The system provides a powerful expansion space, and the vehicle management system can be expanded at the school gate according to needs.
3.3. Temporary card to enter the school park management
3.3.1. Temporary entry and exit personnel (such as parents who enter the school, construction personnel, etc.) will be issued temporary electronic tags by the school security department, and they can enter and leave the school campus with the temporary electronic tags.
3.3.2. Outsiders must enter the campus of the school, apply for registration at the security department, and receive a “temporary card for outsiders” after approval, and set the validity period of the temporary card (the temporary card corresponds to the system management center information such as: someone, ID number : XXX, apply at 9:30 on X, X, X, X year, and valid until 17:30, X, X, X, year X). After receiving the temporary card, foreigners can enter the school campus with the temporary card.
3.3.3. If the electronic tag held by the temporary entry and exit personnel passes in a certain area, the system will automatically perform identity verification. After the system verifies that the card number is valid, it will be released. The system will automatically record the entry time of the relevant personnel. Otherwise, an alarm will be triggered.
3.4. Refer to the installation drawing
Reference installation drawing of the school gate active card reader:
