[0002] Currently, artificial roll call, video monitoring or face recognition access control are commonly used in campus to ensure student safety. Artificial roll call relies on teachers' subjective judgment, has high omission rate and cannot cover non-class periods such as recess; video monitoring can record images, but personnel need to be on duty 24 hours a day to discover abnormalities in time, and it also takes a lot of playback time to take evidence afterwards; face recognition access control relies on cloud computing power, has high construction cost, large recognition delay, and needs to store sensitive facial data for a long time, which brings privacy leakage and regulatory compliance risks. In addition, most existing systems focus on a single scene, such as attendance or access control only; they cannot provide joint early warning for multi-dimensional safety problems such as loss, bullying and sudden injury, and lack the ability to provide electronic fence for young students, prevent alarm from being dismantled, and one-key statistics of the number of students leaving school in disaster. SUMMARY

[0004] Preferably, the RFID smart card component is provided with an anti-disassembly detection circuit, which sends an alarm to the background management terminal when it detects that the card body is broken, shielded or continuously lost for more than a preset time.
[0005] Preferably, the access control component comprises an anti-tailing sensor for triggering an audible and visual alarm when an uncarded person is identified to be tailing.
[0006] Preferably, the security help component is configured with anonymous collaborative alarm logic, when the same help terminal receives not less than two different RFID smart cards within a preset time window, the background management terminal upgrades the alarm level and links the corridor alarm bell and the campus broadcast.
[0007] Preferably, the emergency rescue component automatically pushes the rescue instruction containing the location coordinates to the teacher RFID smart card with first-aid permission identification after receiving the SOS signal.
[0008] Preferably, the background management terminal has an emergency mode, when a school-wide disaster occurs, all access controls are automatically unlocked and a list of students who have not left the building is counted in real time.
[0009] A student on-campus safety management method based on RFID cards, comprising: S1, a student swipes an RFID smart card to access the campus through an access control; S2, an electronic fence positioning component monitors and determines whether the student has crossed the boundary, and if so, the background management terminal issues a warning; S3, a student can anonymously report an alarm by sticking a card at a security help terminal; the background management terminal processes the alarm according to the number of alarms; S4, a student triggers an emergency rescue by pressing the SOS button of the RFID smart card, and the background management terminal distributes the location to first-aid personnel; S5, when the system detects that the RFID smart card is abnormally detached or continuously off-network, the background management terminal generates an abnormal disappearance alarm.
[0010] Preferably, in step S3, when the background management terminal determines that it is a second-level emergency alarm, the corridor alarm bell and the broadcast device are automatically enabled to remind the surrounding faculty and staff.
[0011] Preferably, in step S4, the message content pushed by the background management terminal to the first-aid response team includes at least the identity of the reporting student, the reporting time, and the precise positioning coordinates.
[0012] Preferably, in step S5, after the abnormal disappearance alarm is generated, the background management terminal automatically locks the RFID smart card until the administrator confirms the student's status and unlocks it.
[0013] Compared with the prior art, the present application has the following beneficial effects: (1) The present application integrates four scenes of access control, anti-lost, anti-bullying and emergency rescue into the same RFID technology framework, and forms a closed loop through the access control gate, electronic fence, anonymous help terminal and SOS button. Once any link triggers an alarm, the background immediately presents the event level, student identity and accurate position on the same interface, and automatically pushes it to the corresponding on-duty personnel or first aid team, realizing the whole-process second-level linkage of "discovery, positioning, response and disposal", greatly shortening the information island and reaction time between traditional multiple systems; (2) The present application completely relies on RFID passive induction and local logic control, and can complete safety management without collecting face, voice or behavior trajectory images. All identity data is stored in encrypted form in the school server in the form of hexadecimal card number, which not only reduces the dependence on cloud computing power and the pressure of continuous payment, but also effectively avoids the legal risk of face feature database leakage; (3) The help terminal hidden in the corner of the corridor can quickly report bullying clues without exposing the identity of the student, and the background records but does not display the identity on site; if the same terminal detects multiple student cards to report alarms successively within a set time window, the system automatically upgrades the alarm and links the floor alarm bell, broadcast and security patrol, realizing the group supervision mechanism of multi-person witnessing and upgrading. It breaks through the psychological barrier of previous single-point button false alarm and students' fear of public help, and can significantly improve the discovery rate and intervention success rate of bullying incidents; (4) The RFID smart card of the present application is built-in with micro energy and SOS circuit triggered by long pressing for three seconds. The accurate coordinates can be pushed to the background in less than one second after the nearest card reader captures the signal, and a pop-up window navigation is pushed to the mobile phone app of the nearest three teachers with first aid authority at the same time. In global events such as fire and earthquake, the system can also generate a list of remaining personnel in the building within 30 seconds according to the last card swiping node, winning a golden five-minute rescue window for fire fighting and medical care, and greatly improving the survival rate and disposal efficiency; (5) The RFID card of the present application is integrated with line break detection and shielding detection circuit. Once the card is cut, wrapped in a shielding bag or lost for 120 seconds, the background immediately marks the card as an abnormal disappearance and pushes it to the class teacher and gatekeeper terminal; at the same time, the access control system puts the card in a locked state to prevent illegal use or escape with the card. The defense line and electronic fence are coupled, which can trigger intervention in the early stage of students being coerced or leaving school involuntarily, and plug the security loophole of traditional RFID access control card replacement.

[0015] The technical solutions of the present application will be further described below in combination with the drawings and through specific embodiments.
[0016] The present application provides a kind of student in school safety management system based on RFID card, comprising: RFID smart card component, for student identity recognition, anti-disassembly detection and emergency help (built-in passive RFID chip, micro energy unit, alarm button, LED indicator, disconnect detection circuit);Each student is issued the RFID smart card of unique ID (kindergarten can use bracelet form).Card contains passive RFID chip and small amount of electronic components, such as LED indicator and hidden button. Card has identity recognition and safety help function, usually as school badge or student card wear, ensure that it is not separated from the body. Card can be read in induction area without battery, certain advanced functions (such as button alarm) are supported by built-in micro battery.
[0017] Access control component, set in campus entrance, for reading RFID smart card and controlling passage (set in school gate, dormitory door, teaching building entrance, including card reader gate, anti-following sensor and sound and light alarm device);Install RFID card reader gate or card reader at each entrance of campus, implement automatic registration and permission control of student access.Only personnel with valid student card can pass normally, and the system automatically records time and identity information;If it is detected that no card personnel tries to tailgate or students unauthorized leave school, sound and light alarm is triggered immediately and security personnel is notified to intercept. This module can also be linked with SMS platform, send notification to parents when students enter or exit school gate, and strengthen school cooperation management.
[0018] Electronic fence positioning component, laid in campus perimeter and key passageway, for monitoring student border crossing behavior (constituted by medium distance card reading antenna laid in the inside of fence and key passageway, for monitoring student border crossing or abnormal stay);Deploy medium and short distance RFID card reading device in campus perimeter, kindergarten activity area and key place, form electronic fence and positioning network. When younger students approach school gate or exceed the specified activity area, card reader will sense its card signal and immediately send early warning to teacher and security, prevent young children from losing and leaving school. System can update student location in area in real time, when finding that young children stay in abnormal area for a long time or separate from class team, automatically remind teacher to pay attention. For boarding middle school and university campus, positioning module can be used for night check and emergency search and rescue, guarantee the personal safety of students in vast campus.
[0019] Safety Help Component, including several hidden help terminals, distributed in corridors, stairways, and bathroom entrances, for receiving anonymous help signals from students and uploading; several safety help points (such as corridor corners, stairways, and bathroom entrances) are set up in the campus, equipped with hidden RFID card readers or help terminals. If a student encounters campus bullying or witnesses someone in danger, he or she can trigger an anonymous alarm by approaching the help point without drawing attention. The system will immediately send the location and situation to the on-duty teacher or security guard while protecting the identity of the alarm student, which is only known to the administrator. To improve reliability, the system supports a collaborative alarm mechanism: if multiple student cards trigger the help at the same location within a short period of time, the system will upgrade the alarm level and immediately notify nearby staff through broadcast or alarm bells to intervene quickly. This multi-confirmation method can reduce false alarms and provide greater courage support to the bullied.
[0020] Emergency Rescue Component, linked with the SOS button on the RFID smart card and the nearby card reader, for positioning and notifying rescue (linked with the SOS button on the RFID smart card and the nearby card reader, triggering background map positioning, broadcast notification, and emergency team push); each safety card integrates an emergency button, which can be triggered by long-pressing the hidden button on the card in case of sudden illness, injury, or campus violence. The nearest RFID reading device in the campus will capture the signal and automatically report to the campus security center, and the system interface will immediately pop up the identity and precise location of the trigger alarm. At the same time, teachers, nurses, or security personnel with first aid skills in the nearby area will also receive mobile notifications to arrive at the scene first to handle the situation. This module is equivalent to an emergency call button on the campus, and its silent alarm design ensures that the alarm does not disturb potential perpetrators in critical situations. In addition, the rescue module is linked with the school's emergency plan: if a global event such as a fire or earthquake occurs, the system can quickly count the number of students still in the building and their locations based on the latest card swiping records and positioning data, assisting rescue personnel in efficient search and rescue.
[0021] Background Management Terminal (including campus server, on-duty computer, large screen, and broadcast equipment, for data aggregation, event classification, voice prompt, and log storage), for aggregating data from various components, classifying and handling alarm events, and storing logs locally.
[0022] The RFID smart card assembly is internally provided with a disassembly detection circuit. When the card body is broken, shielded or continuously lost for more than a preset time, an alarm is sent to the background management terminal. The access control assembly includes an anti-tailing sensor for triggering an audible and light alarm when a person without a card is identified to be tailing. The security help assembly is configured with anonymous cooperative alarm logic. When the same help terminal receives help signals of not less than two different RFID smart cards within a preset time window, the background management terminal upgrades the alarm level and links the corridor alarm bell and the campus broadcast. The emergency rescue assembly automatically pushes a rescue instruction containing the position coordinates to the teacher RFID smart card with first-aid permission after receiving the SOS signal. The background management terminal has an emergency mode. When a school-wide disaster occurs, all access controls are automatically unlocked, and the list of students who have not left the building is counted in real time.
[0023] A student on-campus safety management method based on an RFID card, comprising: S1, a student swiping an RFID smart card to enter or exit the campus through an access control; S2, an electronic fence positioning assembly monitoring and judging whether the student has crossed the boundary, and if so, a background management terminal issuing a warning; S3, a student pasting a card on a security help terminal to anonymously report an alarm; the background management terminal processing the alarm according to the number of alarms; S4, a student triggering an emergency rescue by long pressing an RFID smart card SOS button, and the background management terminal distributing the position to first-aid personnel; S5, when the system detects that the RFID smart card is abnormally disassembled or continuously off-network, the background management terminal generating an abnormal disappearance alarm. In step S3, when the background management terminal determines a second-level emergency alarm, the corridor alarm bell and the broadcast device are automatically enabled to remind surrounding teachers and staff. In step S4, the message content pushed by the background management terminal to the first-aid response team includes at least the alarm student identity, alarm time and accurate positioning coordinates. In step S5, after the abnormal disappearance alarm is generated, the background management terminal automatically locks the RFID smart card until the administrator confirms the student status and unlocks the card.
[0024] In a kindergarten scenario, a child swipes a card to pass through an access control gate when entering the kindergarten, and the background records the time of entering the kindergarten. The electronic fence limits the range of activities between the playground and the classroom during the class. If the card reader detects that the child card is close to the door, the background immediately pops up a window to remind the class teacher. When the child is pushed or bullied, the child can paste a card on a security terminal on the corridor wall for help. The background pushes a first-level alarm, and the on-duty teacher arrives within 30 seconds. In an emergency, long press the card SOS key for 3 seconds, the nearest card reader uploads an alarm, and the infirmary and security room receive voice and map coordinates at the same time.
[0025] Boarding school scenario: Night dormitory access card check-in, non-card users are automatically included in the list of non-returning; Teachers can view the last positioning node and trajectory of students in the class through the mobile app; If bullied in the bathroom, students can anonymously report the alarm by sticking the card, if the second card reports within 60 seconds, the corridor alarm will ring immediately and broadcast the floor location; School first aid team (teacher volunteers) card has first aid permission mark, the system automatically assigns the nearest volunteer to participate in the disposal.
[0026] University campus scenario: Medium-range card reading gateway is installed on the main road of the campus, which is used for student distribution heat map with an accuracy of ±5m; If a suspicious person is found following into the laboratory building, the access control alarm will sound and push the snapshot to the security terminal (only for archiving); In case of fire, the administrator activates the emergency mode in the background, the system automatically unlocks all access controls and marks the number and approximate location of students still in the building in real time, providing decision basis for fire rescue.
