[0031] In the related art, in a conventional smart campus management system, there is usually a large-sized display device at the school gate of a kindergarten or K12 school to display information about people entering and leaving the campus. The security guard checks in real time whether the person whose face is scanned is a person from the school based on the information about people entering and leaving the campus. Some schools plan to use discarded TV devices to display information about people entering and leaving the campus in order to save costs. Some schools plan to purchase smart TVs or smart screens by themselves to display information about people entering and leaving the campus. Some schools plan to use discarded large-sized e-class signs to display information about people entering and leaving the campus. Therefore, it is necessary to develop an APP separately for each type of display device to adapt to its device hardware parameters. Different schools require different management systems, resulting in a large amount of development work and a lot of duplicate development work.

[0032] To overcome the above problems, the present disclosure provides a campus access management system based on face recognition technology. The campus access management system includes: an intelligent device, which is built-in with campus access management application software and is configured to receive management information of people entering and leaving the campus and generate a display signal based on the management information of people entering and leaving the campus and output it; an MQTT service platform, which is configured to add and register the intelligent device and distribute the management information of people entering and leaving the campus to the intelligent device based on the MQTT topic subscribed by the intelligent device; an access gate with a face collection and recognition function, which is set at the school gate and is configured to collect and recognize images of people entering and leaving the campus and publish basic information of people entering and leaving the campus to the MQTT service platform in real time based on the recognition result, wherein the MQTT service platform assembles and generates the management information of people entering and leaving the campus based on the basic information of people entering and leaving the campus; and a display device, which is configured to receive the display signal from the intelligent device and present the display information of people entering and leaving the campus, and the display information of people entering and leaving the campus includes at least a part of the management information of people entering and leaving the campus.

[0033] The present disclosure distributes the management information of people entering and leaving the campus to the intelligent device subscribing to the MQTT topic in real time through face recognition technology and MQTT technology, and the display device presents the display information of people entering and leaving the campus in real time, which is convenient for the management of people entering and leaving the campus. The intelligent device and the display device are independently set and are built-in with campus access management application software. The intelligent device is applicable to various types and models of display devices and does not require software development for specific display hardware, reducing management costs.

[0034] The optional embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0035] Figure 1 The structural schematic diagram of a campus access management system based on face recognition technology provided by some embodiments of the present disclosure is shown. As Figure 1As shown, some embodiments of the present disclosure provide a campus access management system 100 based on face recognition technology. The campus access management system includes an intelligent device 10, an MQTT service platform 20, an access gate 30 with a face collection and recognition function, and a display device 40. The campus access management system 100 can be applied to multiple schools simultaneously. Figure 1 Taking three schools as an example, the intelligent device 10 includes a first intelligent device 11, a second intelligent device 12, and a third intelligent device 13 located in the first school, the second school, and the third school respectively. The access gate 30 with a face collection and recognition function includes a first access gate 31, a second access gate 32, and a third access gate 33 located in the first school, the second school, and the third school respectively. The display device 40 includes a first display device 41, a second display device 42, and a third display device 43 located in the first school, the second school, and the third school respectively. The MQTT service platform 20 serves the first school, the second school, and the third school.

[0036] The intelligent device 10 is built-in with campus access management application software, configured to receive the management information of the personnel entering and leaving the campus, generate the display information of the personnel entering and leaving the campus based on the management information of the personnel entering and leaving the campus, and output a display signal.

[0037] Specifically, the first intelligent device 11, the second intelligent device 12, and the third intelligent device 13 adopt the same structure, and each of them is built-in with campus access management application software. The first intelligent device 11, the second intelligent device 12, and the third intelligent device 13 respectively receive the management information of the personnel entering and leaving the campus in the first school, the second school, and the third school, and send the display information of the personnel entering and leaving the campus corresponding to the first school, the second school, and the third school generated based on the management information of the personnel entering and leaving the campus in the first school, the second school, and the third school, and output the first display signal, the second display signal, and the third display signal.

[0038] After the intelligent device 10 is powered on, it automatically enters the management application software interface. The intelligent device can output display signals in protocols such as HDMI, VGA, and USB, which can meet the display signal input requirements of various display devices.

[0039] The MQTT service platform 20 is configured to add and register the intelligent device 10, and distribute the management information of the personnel entering and leaving the campus to the intelligent device 10 based on the MQTT topic subscribed by the intelligent device 10.

[0040] Specifically, the MQTT service platform 20 is, for example, set up at the service provider for campus access management, and provides data subscription and distribution services for multiple schools. The MQTT service platform 20 is used to add and register the first intelligent device 11, the second intelligent device 12, and the third intelligent device 13, and distribute the management information of the personnel entering and leaving the campuses of the first school, the second school, and the third school to the first intelligent device 11, the second intelligent device 12, and the third intelligent device 13 respectively based on the MQTT topics subscribed by the first intelligent device 11, the second intelligent device 12, and the third intelligent device 13.

[0041] The access gate 40 with a face collection and recognition function is set at the campus entrance, configured to collect and recognize the images of the personnel entering and leaving the campus, and publish the basic information of the personnel entering and leaving the campus to the MQTT service platform 20 in real time based on the recognition result. Among them, the MQTT service platform assembles and generates the management information of the personnel entering and leaving the campus based on the basic information of the personnel entering and leaving the campus.

[0042] Specifically, the first access gate 41, the second access gate 42, and the third access gate 43 with a face collection and recognition function are respectively set at the campus entrances of the first school, the second school, and the third school, and respectively collect and recognize the images of the personnel entering and leaving the campuses of the first school, the second school, and the third school in real time, and publish the basic information of the personnel entering and leaving the campuses of the first school, the second school, and the third school to the MQTT service platform 20 in real time based on the recognition result.

[0043] The MQTT service platform 20 assembles and generates the management information of the personnel entering and leaving the campuses of the first school, the second school, and the third school based on the basic information of the personnel entering and leaving the campuses of the first school, the second school, and the third school.

[0044] The display device 40 is configured to receive the display signal from the intelligent device 10 and present the display information of the personnel entering and leaving the campus, and the display information of the personnel entering and leaving the campus includes at least a part of the management information of the personnel entering and leaving the campus.

[0045] Specifically, the first display device 41, the second display device 42, and the third display device 43 respectively receive the first display signal, the second display signal, and the third display signal from the corresponding first intelligent device 11, the second intelligent device 12, and the third intelligent device 13, and present the display information of the personnel entering and leaving the campuses of the first school, the second school, and the third school based on the first display signal, the second display signal, and the third display signal. The display information of the personnel entering and leaving the campuses of the first school, the second school, and the third school respectively includes at least a part of the management information of the personnel entering and leaving the campuses of the first school, the second school, and the third school.

[0046] The first display device 41, the second display device 42, and the third display device 43 can be display devices of different types, different sizes, and different resolutions. For example, they can be ordinary display devices that cannot install application programs, or intelligent display devices that can install application programs, etc. Different schools can select appropriate display devices according to actual situations. For example, they can use discarded large-size electronic class signs as display devices, or purchase smart TVs or smart screens as display devices.

[0047] Through the face recognition technology and MQTT technology of the present disclosure, the management information of personnel entering and leaving the campus is distributed to intelligent devices subscribing to the MQTT topic in real time, and the display device presents the display information of personnel entering and leaving the campus in real time, facilitating the management of personnel entering and leaving the campus. The intelligent device and the display device are independently set, with campus access management application software built-in. The intelligent device is applicable to various types and models of display devices. Schools can select appropriate display devices by themselves without developing software for specific display hardware, reducing management costs.

[0048] In some embodiments, the management application software is configured to set the intelligent device ID and the MQTT service IP port to establish an MQTT connection with the MQTT service platform 20 to complete the addition and registration of the intelligent device 10 on the MQTT service platform 20.

[0049] Figure 2 The flowchart of adding and registering the intelligent device on the MQTT service platform is shown. As Figure 2 shown, in step S100, the intelligent device ID is obtained. Specifically, the campus access management application software obtains the ID of the intelligent device 10, such as an identification code.

[0050] In step S200, the campus access management application software sets the intelligent device ID and the MQTT service IP port, and executes the registration of the intelligent device on the MQTT service platform. Specifically, the campus access management application software sets the intelligent device ID and the specific school it matches, and sets the MQTT service IP port, and sends a registration request of the intelligent device 10 to the MQTT service platform.

[0051] In step S300, it is judged whether the registration is successful. Specifically, the MQTT service platform determines whether the intelligent device with the campus access management application software built-in is a legal device based on the intelligent device ID. If it is a legal device, the registration is successful, and step S400 is executed; otherwise, the registration fails, and step 500 is executed.

[0052] In step S400, the intelligent device with the built-in campus access management application software subscribes to the MQTT topic and starts to receive the management information of the personnel entering and leaving the campus. Specifically, the intelligent device 10 receives the management information of the personnel entering and leaving the campus corresponding to the basic information of the personnel entering and leaving the campus published by the access control gate 30 it is concerned about.

[0053] In step S500, check whether the set intelligent device ID and the MQTT service IP port are correct, and return to step S200.

[0054] In some embodiments, the MQTT topics subscribed by the intelligent device include the basic information of the personnel entering and leaving the campus published by the access control gate 30 corresponding to the intelligent device 10. Specifically, the first intelligent device 11 is concerned about subscribing to the basic information of the personnel entering and leaving the campus of the first school published by the first access control gate 31, the second intelligent device 12 is concerned about subscribing to the basic information of the personnel entering and leaving the campus of the second school published by the second access control gate 32, and the third intelligent device 13 is concerned about subscribing to the basic information of the personnel entering and leaving the campus of the third school published by the third access control gate 33.

[0055] The MQTT service platform 20 assembles and generates the management information of the personnel entering and leaving the first school, the second school, and the third school based on the basic information of the personnel entering and leaving the first school, the second school, and the third school, and distributes the management information of the personnel entering and leaving the first school, the second school, and the third school to the first intelligent device 11, the second intelligent device 12, and the third intelligent device 13 in real time.

[0056] In some embodiments, as Figure 1 shown, the campus access management system 100 further includes a cloud storage 50, which is, for example, a cloud storage server rented by the campus access management service provider. The cloud storage 50 stores the head portrait pictures of the recorded personnel. The recorded personnel are, for example, students, parents of students, teaching staff, etc. The head portraits of the recorded personnel are pre-recorded in the cloud storage device. Specifically, the head portrait pictures of the recorded personnel in the three schools are all recorded in the storage 50, and each head portrait picture has a unique storage address in the cloud storage.

[0057] When the access control gate 30 identifies that the personnel entering and leaving the campus are the recorded personnel, the management information of the personnel entering and leaving the campus includes the storage address of the head portrait picture of the recorded personnel in the cloud storage. The intelligent device 10 obtains the head portrait picture of the recorded personnel based on the storage address, and the display information of the personnel entering and leaving the campus includes the head portrait picture of the recorded personnel.

[0058] Specifically, each of the first access control gate 31, the second access control gate 32, and the third access control gate 33 determines whether the person entering or leaving the campus is a registered person based on face recognition technology. When it is recognized that the person entering or leaving the campus is a registered person, the access control gate 30 immediately publishes the basic information of the campus personnel. The basic information of the campus personnel includes the registered person ID, the access control gate ID, and the entry and exit time and direction. The MQTT service platform 20 immediately assembles and generates the management information of the campus personnel based on the basic information of the campus personnel entering or leaving the campus. Specifically, for example, based on the registered person ID, the registered person type information, the registered person profile information, and the storage address of the registered person's avatar picture in the cloud storage are retrieved. Based on the access control gate ID, the corresponding school ID, the specific location information of the gate, etc. are retrieved. The specific location information of the gate is, for example, the school gate number where the access control gate is located.

[0059] In some embodiments, assembling and generating the management information of the campus personnel entering or leaving the campus, for example, includes the school ID, the registered person type, the registered person's entry and exit time, the registered person's entry and exit direction, and the storage address of the registered person's avatar picture in the cloud storage, etc.

[0060] The intelligent device 10 obtains the avatar picture of the registered person based on the storage address of the avatar picture of the registered person in the cloud storage, and integrates at least part of the information of the campus personnel management information to generate the display information of the campus personnel entering or leaving the campus and outputs a display signal.

[0061] For example, the management information of the campus personnel entering or leaving the campus includes the school ID, the registered person type, the registered person's entry and exit time, the registered person's entry and exit direction, and the storage address of the registered person's avatar picture in the cloud storage. The display information of the campus personnel entering or leaving the campus includes the school ID, the registered person type, the registered person's entry and exit time, the registered person's entry and exit direction, and the avatar picture of the registered person.

[0062] In some embodiments, when the registered person is a student, the management information of the campus personnel entering or leaving the campus further includes the name of the registered student, the grade and class number of the registered student, the student ID of the registered student, and the type of the registered student. The display information of the campus personnel entering or leaving the campus further includes the name of the registered student, the grade and class number of the registered student, the student ID of the registered student, and the type of the registered student.

[0063] In some embodiments, when the registered person is a faculty or staff member, the management information of the campus personnel entering or leaving the campus further includes the name of the registered faculty or staff member, the position of the registered faculty or staff member, and the staff number of the registered faculty or staff member. The display information of the campus personnel entering or leaving the campus further includes the name of the registered faculty or staff member, the position of the registered faculty or staff member, and the staff number of the registered faculty or staff member.

[0064] In some embodiments, when the recorded person is a student's parent, the management information of the personnel entering and leaving the campus further includes the student's name, student's grade and class number, student's school number, and the type of relationship between the parent and the student, and the display information of the personnel entering and leaving the campus further includes the student's name, student's grade and class number, student's school number, and the type of relationship between the parent and the student.

[0065] In some embodiments, the access gate 30 further has the function of measuring the body temperature of the entering and leaving personnel in real time, and the basic information of the personnel entering and leaving the campus and the management information of the personnel entering and leaving the campus both further include the body temperature information of the recorded person.

[0066] In some embodiments, when the access gate 30 identifies that the person entering and leaving the campus is a recorded person, it can also determine whether the time for the recorded person to enter and leave the campus belongs to the time period of the access permission enjoyed by the person. If not, specific marking is performed on the management information of the personnel entering and leaving the campus. Specifically, if a recorded person enters or leaves the school during a specific period, such as a non-school-going or leaving-school time period, the time of their entry and exit is marked as an illegal time, and the illegal time periods corresponding to different recorded persons can be different.

[0067] In some embodiments, the campus access management application software built in the intelligent device 10 obtains the management information of the personnel entering and leaving the campus from the MQTT service platform 20 by subscribing to a topic. The transmission format between the campus access management application software and the MQTT service platform 20 is JSON. When the person entering and leaving the campus is a recorded person, the transmission fields are as shown in Tables 1 to 3 below:

[0075] In one embodiment, when the access gate identifies that the person entering and leaving the campus is an unrecorded person, the basic information of the campus personnel includes an unrecorded mark, the access gate ID, the entry and exit time and direction, and the image of the unrecorded person. The management information of the personnel entering and leaving the campus further includes the school ID, the unrecorded mark, the entry and exit time, the entry and exit direction, and the image of the unrecorded person. The display information of the personnel entering and leaving the campus includes the school ID, the unrecorded mark, the entry and exit time, the entry and exit direction, and the image of the unrecorded person.

[0076] In some embodiments, the display device 40 slides to present the management information of the personnel entering and leaving the campus. The management information of the personnel entering and leaving the campus is scrolled and presented along a predetermined direction according to the classification of entry and exit and the entry and exit time. The management application software adaptively sets the number of pieces of the display information of the personnel entering and leaving the campus presented simultaneously according to the size and resolution of the display device.

[0077] Figure 3 The schematic diagram showing the display device presenting the management information of the personnel entering and leaving the campus is shown as Figure 3 shown. In the display interface of the display device 40, the school name is presented in the middle position at the top of the display interface, and the school name is determined based on the school ID.

[0078] The area below the school name is divided into left and right parts. The left part presents the information of the personnel entering the school, and the right part presents the information of the personnel leaving the school. The information of the personnel entering the school in the left part is presented in the left part in sequence according to the entry time. The newly obtained information of the personnel entering the school is presented at the bottom left, and moves up one grid as the next information of the personnel entering the school is presented, until it disappears after moving to the top left. Among them, through the enlarged display grid area, it is convenient for the staff at the school gate to identify. The information of the personnel entering the school in the right part is presented in the right part in sequence according to the entry time. The newly obtained information of the personnel leaving the school is presented at the top right, and moves down one grid as the next information of the personnel leaving the school is presented, until it disappears after moving to the bottom right. Among them, through the enlarged display grid area, it is convenient for the staff at the school gate to identify.

[0079] Figure 3 Only the content of the display information of the personnel entering and leaving the campus is exemplarily shown in, and it can display all or part of the information of the display information of the personnel entering and leaving the campus, which can be specifically set in the campus access management application software.

[0080] In some embodiments, the management application software adaptively sets the number of pieces of the display information of the personnel entering and leaving the campus presented simultaneously according to the size and resolution of the display device 40, and the number of grids occupied by the information of the personnel entering and leaving the campus on the left and right sides, so that the number of pieces of the display information of the personnel entering and leaving the campus presented simultaneously is appropriate, that is, it ensures that the staff at the school gate can clearly identify, and presents as much display information of the personnel entering and leaving the campus as possible.

[0081] In some embodiments, the management application software can set the screen clearing time interval of the display device 40. When no new management information of the personnel entering and leaving the campus is received within a predetermined time, it controls the display device 40 to clear the display information of the personnel leaving the campus presented on the screen before.

[0082] In some embodiments, when the person entering or leaving is a stranger, the management application software controls the display device to mark the information with a warning box when presenting the corresponding display of the person entering or leaving the campus. For example, it is marked with a red flashing box, and at the same time, an alarm sound can be emitted to remind the staff at the school gate.

[0083] In some embodiments, when the person entering or leaving is a registered person, but their entry and exit time is an illegal time, that is, the entry and exit time is outside the specified entry and exit times, the management application software controls the display device to mark the information with a warning box when presenting the corresponding display of the person entering or leaving the campus. For example, it is marked with a yellow box, and at the same time, an alarm sound can be emitted to remind the staff at the school gate.
