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

[0037] Specifically, the first intelligent device 11, the second intelligent device 12 and the third intelligent device 13 adopt the same structure, each of which 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 receive access campus personnel management information of the first school, the second school and the third school respectively, and send corresponding access campus personnel display information of the first school, the second school and the third school generated based on the access campus personnel management information of the first school, the second school and the third school, and output first display signals, second display signals and third display signals.

[0038] After the intelligent device 10 is turned on, it automatically enters the management application software interface. The intelligent device can output display signals of HDMI, VGA, USB and other protocols, 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 access campus personnel management information to the intelligent device 10 based on the MQTT topic subscribed by the intelligent device 10.

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

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

[0042] Specifically, the first access gate 41, the second access gate 42, and the third access gate 43 with face collection and recognition function are arranged at the campus entrances of the first school, the second school, and the third school, respectively, and collect and recognize the images of the access personnel of the first school, the second school, and the third school in real time, respectively, and publish the access personnel basic information 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 access personnel management information of the first school, the second school, and the third school based on the access personnel basic information of the first school, the second school, and the third school.

[0044] The display device 40 is configured to receive display signals from the smart device 10 and present the access personnel display information, wherein the access personnel display information includes at least part of the access personnel management information.

[0045] Specifically, the first display device 41, the second display device 42, and the third display device 43 receive the first display signal, the second display signal, and the third display signal from the corresponding first smart device 11, the second smart device 12, and the third smart device 13, respectively, and present the access personnel display information 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 access personnel display information of the first school, the second school, and the third school includes at least part of the access personnel management information of the first school, the second school, and the third school, respectively.

[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 common display devices that cannot install applications, or smart display devices that can install applications, and the like. Different schools can select appropriate display devices according to actual conditions. For example, large-size electronic class boards that are no longer in use can be used as display devices, or smart TVs or smart screens can be purchased as display devices.

[0047] The present disclosure distributes the personnel management information in and out of the campus to the smart devices subscribing to the MQTT topic in real time through the face recognition technology and the MQTT technology, and displays the personnel information in and out of the campus in real time by the display device, which facilitates the management of the personnel in and out of the campus. The smart device and the display device are independently arranged, and the campus in-out management application software is built-in. The smart device is applicable to various types and models of display devices, and the school can select appropriate display devices by itself without the need of developing software for specific display hardware, thereby reducing the management cost.

[0048] In some embodiments, the management application software is configured to set the smart 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 smart device 10 on the MQTT service platform 20.

[0049] Figure 2 A flowchart of the addition and registration of the smart device on the MQTT service platform is shown. As shown in Figure 2 In step S100, the smart device ID is obtained. Specifically, the campus in-out management application software obtains the ID of the smart device 10, for example, an identity code.

[0050] In step S200, the campus in-out management application software sets the smart device ID and the MQTT service IP port, and performs the registration of the smart device on the MQTT service platform. Specifically, the campus in-out management application software sets the smart device ID and the specific school matched therewith, and sets the MQTT service IP port, and sends a registration request of the smart device 10 to the MQTT service platform.

[0051] In step S300, it is determined whether the registration is successful. Specifically, the MQTT service platform determines whether the smart device with the built-in campus in-out management application software is a legal device based on the smart device ID. If it is a legal device, the registration is successful, and step S400 is performed. Otherwise, the registration fails, and step S500 is performed.

[0052] In step S400, the smart device with the built-in campus access management application subscribes to the MQTT topic and starts to access the access campus personnel management information, specifically, the smart device 10 receives the access campus personnel management information corresponding to the access campus personnel basic information published by the access gate 30 it focuses on.

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

[0054] In some embodiments, the MQTT topic subscribed by the smart device includes the access campus personnel basic information published by the access gate 30 corresponding to the smart device 10. Specifically, the first smart device 11 focuses on subscribing to the access campus personnel basic information of the first school published by the first access gate 31, the second smart device 12 focuses on subscribing to the access campus personnel basic information of the second school published by the second access gate 32, and the third smart device 13 focuses on subscribing to the access campus personnel basic information of the third school published by the third access gate 33.

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

[0056] In some embodiments, as shown in Figure 1 The campus access management system 100 further includes a cloud storage 50, which is a cloud storage server rented by a campus access management service provider, for example, and the cloud storage 50 stores the head portrait of the registered personnel, such as students, student parents, faculty and staff, etc. The head portrait of the registered personnel is input into the cloud storage device in advance. Specifically, the head portraits of the registered personnel of the three schools are input into the storage 50, and each head portrait has a unique storage address in the cloud storage.

[0057] When the access gate 30 identifies that the access campus personnel is a registered personnel, the access campus personnel management information includes the storage address of the head portrait of the registered personnel in the cloud storage, the smart device 10 obtains the head portrait of the registered personnel based on the storage address, and the access campus personnel display information includes the head portrait of the registered personnel.

[0058] Specifically, each of the first entry / exit gate 31, the second entry / exit gate 32, and the third entry / exit gate 33 uses facial recognition technology to determine whether the person entering or leaving the campus is a registered person. When the person entering or leaving the campus is identified as a registered person, the entry / exit gate 30 publishes basic campus personnel information in real time. This basic campus personnel information includes the registered person ID, the entry / exit gate ID, and the entry / exit time and direction. The MQTT service platform 20 assembles and generates the campus personnel management information in real time based on the basic campus personnel information. Specifically, for example, it retrieves the registered person type information, registered person data information, and the storage address of the registered person's headshot image in the cloud storage based on the registered person ID, and retrieves the corresponding school ID and the specific location information of the gate based on the entry / exit gate ID. The specific location information of the gate is, for example, the school gate number of the school where the entry / exit gate is located.

[0059] In some embodiments, the information generated for managing personnel entering and leaving the campus includes, for example, the school ID, the type of registered personnel, the entry and exit time of registered personnel, the direction of entry and exit of registered personnel, and the storage address of the registered personnel's headshot image in the cloud storage.

[0060] The intelligent device 10 obtains the headshot image of the registered person based on the storage address of the headshot image in the cloud storage, integrates at least part of the campus personnel management information to generate campus entry and exit personnel display information, and outputs a display signal.

[0061] For example, the campus access personnel management information includes the school ID, the type of registered personnel, the entry and exit time of registered personnel, the entry and exit direction of registered personnel, and the storage address of the registered personnel's headshot image in the cloud storage. The campus access personnel display information includes the school ID, the type of registered personnel, the entry and exit time of registered personnel, the entry and exit direction of registered personnel, and the headshot image of registered personnel.

[0062] In some embodiments, when the registered personnel are students, the campus access personnel management information also includes the registered student's name, registered student's grade and class number, registered student's ID number, and registered student type. The campus access personnel display information also includes the registered student's name, registered student's grade and class number, registered student's ID number, and registered student type.

[0063] In some embodiments, when the registered personnel are faculty and staff, the campus access personnel management information also includes the registered faculty and staff name, the registered faculty and staff position, and the registered faculty and staff employee number, and the campus access personnel display information also includes the registered faculty and staff name, the registered faculty and staff position, and the registered faculty and staff employee number.

[0064] In some embodiments, when the registered person is a student's parent, the access management information further comprises the student's name, the student's grade, the student's class number, the student's ID number, and the relationship type between the parent and the student, and the access display information further comprises the student's name, the student's grade, the student's class number, the student's ID number, and the relationship type 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 access person in real time, and the access management information and the access management information further comprise the body temperature information of the registered person.

[0066] In some embodiments, when the access person is identified as a registered person, the access gate 30 can further determine whether the access time of the registered person belongs to the time period of the access permission enjoyed by the registered person. If not, the access management information is specially marked. Specifically, if the registered person accesses the school during a specific period, such as a non-school or off-campus period, the access time of the registered person is marked as illegal time. The illegal time period corresponding to different registered persons can be different.

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