Description

Technical Field

[0001] This invention belongs to the field of smart campus security technology, specifically relating to a smart campus entrance and exit control system that integrates radio frequency identification (RFID) and computer vision technologies. Background Technology

[0003] When school staff enter the campus to go to work or class, it's different from clocking in at a regular office building. Usually, a large number of people flood in within a short period of time. The few security personnel stationed at the school gate can hardly keep an eye on the crowd at all times and distinguish whether there are outsiders who have broken in. Moreover, faculty and staff can wear personal clothing to work, while students from other schools or delinquent youths can borrow identical school uniforms to impersonate students of the school. It is almost impossible to distinguish them. So when these abnormal outsiders enter the campus, at best they will disrupt the teaching order, and at worst they will cause serious accidents and endanger the lives of school staff.

[0004] The same dense influx of people into the campus, if a check-in process is added, will cause congestion and affect the teaching process. If students do not arrive at school on time, when teachers and staff find out that the students are absent during class or roll call, regardless of whether the students skipped school or had an accident on the way, a lot of time may have passed, and the time to respond in time will be missed, and the probability of students being in danger will increase accordingly.

[0005] Campus safety management currently faces two core challenges:

[0006] 1. The Dilemma of Identity Verification:

[0007] During peak student arrival times (such as morning rush hour), the large flow of people makes it difficult for security personnel to identify outsiders who have infiltrated the crowd in real time.

[0008] Outsiders can infiltrate the school by disguising themselves in school uniforms, rendering traditional visual inspections ineffective.

[0009] 2. Blind spots in school attendance status:

[0010] Student absence information relies on classroom roll call feedback, which has a delay of several hours and cannot respond promptly to truancy or unexpected events on the way to school;

[0011] Manual registration and check-in can easily cause congestion and affect traffic efficiency.

[0012] Existing access control systems (such as card-swipe turnstiles) are difficult to adapt to peak traffic scenarios on campus, and there is an urgent need for an intelligent solution that enables seamless access, real-time verification, and proactive early warning. Summary of the Invention

[0013] (I) Technical problems to be solved

[0014] This invention aims to solve:

[0015] 1. Accurate identification in dense crowds: Real-time differentiation between authorized personnel and unauthorized intruders when passing through areas without requiring active cooperation;

[0016] 2. Real-time synchronization of student attendance status: Automatically push student attendance information to parents' devices to enable early detection and intervention of absences;

[0017] Rapid response to abnormal events: Immediately alert security personnel upon identifying abnormal targets and coordinate their response.

[0070] Figure 1 This is a schematic diagram of the campus intelligent access control management system based on RFID and image fusion recognition according to the present invention.

[0071] Figure 2 This is a schematic diagram of the campus intelligent access control management system based on RFID and image fusion recognition according to the present invention. Detailed Implementation

[0072] The present invention will now be described in further detail with reference to the accompanying drawings.

[0073] Example 1

[0074] To solve the above-mentioned technical problems, the technical solution provided by this invention is: a campus intelligent access control management system based on RFID and image fusion recognition, combined with the appendix. Figure 1This includes: a monitoring center based on RFID technology and equipped with image recognition technology. The monitoring center includes a data processing server with a control system. RFID technology is also known as radio frequency identification technology. This application involves installing relevant instruments and systems at the entrances and exits of the campus. A corresponding RFID electronic identification tag is pre-installed on appropriate accessories, clothing, and bags such as school uniforms, school badges, school bags, watches, etc., on legally authorized personnel entering the campus. The information of these personnel is pre-entered into the access control management system. When personnel enter the campus, the RFID-based system and related identification equipment identify them one by one, just like centralized scanning or remote IC card swiping. They are screened according to whether they are authorized, thereby preventing other unrelated personnel from entering the campus during peak periods, along with the flow of teachers and students going to work or school, thus creating campus security risks.

[0075] Combined with appendix Figure 2 The data processing server includes an RFID management center and an image processor. The RFID management center includes all peripheral components except for readers, electronic tags, etc., which constitute RFID identification devices and systems that support the effective execution of the RFID identification process. The additional image processor is to facilitate security personnel to intuitively view the facial features of abnormal persons and promptly identify them from the crowd to prevent them from entering.

[0076] It also includes an inspection terminal carried by people entering the school, which works with RFID technology for identification. The inspection terminal is equipped with a low-frequency activated electronic tag that works in conjunction with a long-range RFID reader. As the object to be identified, it is an indispensable and important component in the implementation of RFID technology. Currently, with the development of technology, the physical structure of electronic tags is generally very small, thin, and soft, making it easy to place on most items carried by the person.

[0077] Since school badges are required to be worn by almost all students and faculty members on campus, and the cost of embedding them into matching RFID electronic tags is low and the method is simple, and they are rarely cleaned or replaced daily, this application uses school badges as the carrier for low-frequency activation electronic tags.

[0078] The monitoring center's front-end and back-end are respectively equipped with an identification terminal that matches the inspected end and a feedback terminal that informs the RFID identification terminal. The feedback terminal broadcasts information about abnormal personnel for campus security personnel to view, thereby assisting in campus security management. The feedback terminal is a derivative part after the normal use of RFID technology, and its main purpose here is to allow personnel to know and view the identification and detection results.

[0079] The identification terminal includes a long-range RFID reader installed at the campus entrance and exit, which is associated with the RFID management center, and multiple optical cameras that are interconnected with the image processor and used to capture the image features of people. The reader is the active scanning, identification and detection module of the corresponding electronic tag in RFID technology. The camera also has the function of detection, identification and information collection. It is used to record and take pictures, so that the appearance, experience, clothing characteristics of abnormal persons and their geographical location can be displayed on the screen later. The long-range RFID reader is also equipped with a low-frequency activator and an activation antenna.

[0080] The feedback terminal includes an alarm that uses sound and light to alert abnormal personnel and remind security personnel, and a display screen that allows security personnel to view information related to abnormal personnel. Both the alarm and the display screen are configured to be interconnected with the RFID management center, and the display screen is also interconnected with the image processor.

[0081] The alarm uses a buzzer and a flashing warning light, and the display screen includes a query interface and a reset button for stopping the buzzer and warning light.

[0082] The monitoring center is equipped with a storage space that is interconnected with the image processor to temporarily store the information captured by the cameras. The display screen extracts relevant image information from the storage space and displays the characteristic images of abnormal persons on the query interface.

[0083] The equipment in the feedback terminal will only be activated when an abnormal alarm is received. Under normal circumstances, there will be no abnormal movement, meaning that security personnel do not need to pay special attention to it at all times.

[0084] When this part of the equipment and system is triggered, firstly, in terms of sensory perception, the piercing sound of the buzzer and the flashing light of the warning light will alert a wide range of people, including security personnel and people who have illegally entered the campus. This not only informs security personnel that there are abnormal people who have entered the campus and that they need to be investigated, stopped, or even driven away, but also warns abnormal intruders hiding in the crowd to stop their illegal entry into the campus.

[0085] The display will be scanned by the RFID and captured by the camera, but the image of the person whose low-frequency activated electronic tag is registered in this access control system cannot be recognized by the long-range RFID reader. The image is presented as a series of photos or videos. After the security personnel know the information in the image, they enter the crowd, find the abnormal person, and prevent him / her from entering the campus.

[0086] Subsequent actions to complement this process may include expelling suspicious individuals, registering and granting access to off-campus personnel, and verifying the identities of suspicious individuals by entering the information into the system. The specific actions will be handled according to the objective circumstances, requirements, and regulations on site, and there are no specific framework restrictions here.

[0087] Example 2

[0088] In addition, a campus intelligent access control management system based on RFID and image fusion recognition, combined with... Figure 1-2 It also includes mobile applications on parents' phones for receiving messages about students arriving at school or not arriving;

[0089] The mobile terminal is installed on the parents' mobile phones in the form of APP, mini program, etc. The monitoring center sends the identified and registered student entry information to the corresponding mobile terminal in the form of message;

[0090] First, we plan information receiving carriers for mobile terminals, including developing corresponding apps, WeChat mini-programs, or directly using SMS mass messaging platforms to send text messages to parents' mobile phones and other reasonable notification methods. Second, we will distinguish between the RFID school badges worn by students and those worn by faculty and staff. After the long-range RFID reader identifies the low-frequency activated electronic tag in the student's school badge, it will be compared and classified by the data processing server, and then the student's arrival information will be sent to the mobile terminal. The arrival information includes, but is not limited to, the student's name and arrival time.

[0091] Thresholds, or timetables, can be set within the monitoring center. When the time exceeds the timetable, students who have not arrived at school are considered "absent" or "out of contact," and a notification is sent to their mobile devices.

[0092] The display screen at the feedback terminal also includes an identification and sending module for proactively sending verified information about enrolled students to the mobile device;

[0093] Based on objective needs, there are certainly situations in reality where students forget to bring their school badges. Therefore, a manual assisted identification check-in function should be set up. This function is an extension of the feedback end function for identifying outsiders mentioned above. Students of this school who do not bring their school badges are still considered abnormal persons. After the security personnel verify their identity, the security personnel use the identification module in the display screen to send the student's arrival information to the mobile terminal.

[0094] In practical implementation, when students and faculty members flock to the campus from the school gate in the morning or afternoon, the long-range RFID reader in the campus access control system scans the area through which the crowd passes. It emits a signal wave through radio frequency technology. When it detects the corresponding low-frequency activated electronic tag carried by a person, it receives a response. If the person meets the access standard, the access control system will allow them to pass. Specifically, the access control system and related equipment will not make any special reaction. At the same time, the monitoring center will send the arrival information of the students among the people to the corresponding mobile devices one by one.

[0095] When the identification device and data processing server detect an unusual person in the crowd, the alarm will activate first, the buzzer will sound, and the warning light will illuminate. At this time, security personnel will be notified and come to the display screen to check the unusual person. Based on the information provided by the feedback device, they can easily and quickly locate the unusual person in the crowd and take appropriate follow-up actions. If the unusual person is found to be a student of the school after their identity information has been verified, they will be allowed to pass by the security personnel. At the same time, the identification module in the feedback device will also send the student's arrival information to the corresponding mobile device, avoiding unnecessary anxiety and misunderstandings for parents.

[0096] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
