Referring to the embodiment shown in fig. 1, the access control system may include: the system comprises a Bluetooth interaction device, a UWB positioning device, an entrance guard gate device, a man-machine interaction device, a millimeter wave imaging device and a wireless communication device.
Specifically, the Bluetooth interaction device is used for realizing data interaction based on Bluetooth communication; the UWB positioning device is used for realizing short-range positioning based on UWB signals; the entrance guard gate device is used for opening or closing an entrance guard channel; the entrance guard control device is used for controlling the entrance guard gate device according to the data of the Bluetooth interaction device or/and the UW B positioning device.
As a more specific scheme, the Bluetooth interaction device forms data connection with the entrance guard control device so that the user mobile phone forms data interaction with the entrance guard control device through the Bluetooth interaction device; the UWB positioning device and the entrance guard control device form data connection so that the UWB positioning device at least feeds back positioning data of a user mobile phone to the entrance guard control device; the entrance guard gate device and the entrance guard control device form data connection so that the entrance guard control device outputs a control command to the entrance guard gate device.
When a user enters a teaching building or a classroom, the user opens an APP or a small program application of a mobile phone, the user scans a two-dimensional code at an entrance guard device by using the mobile phone, the two-dimensional code can be fixedly and directly adhered at the entrance guard, and can also be dynamic and displayed by a touch screen of a human-computer interaction device in the system.
After a user scans the two-dimensional code by using the mobile phone, the mobile phone acquires the mac address of the door Bluetooth interaction device and data required by matching, so that the mobile phone and the Bluetooth interaction device form Bluetooth connection, the user can acquire a face image through a camera of the mobile phone and then transmit the face image to the access control device through the Bluetooth interaction device, the access control device identifies the identity and the authority of the user through the image data of the two people, if the user has the authority of entering the access control, the UWB positioning function is opened by the mobile phone of the user through the Bluetooth connection, and the mobile phone and the user are bound in a real name mode.
A concentrated area with a mobile phone can be arranged near the entrance guard gate device, when a user needs to place the mobile phone in the concentrated area, the position of the mobile phone can be positioned through UWB signal interaction of a UWB positioning device and the mobile phone (at the moment, the mobile phone is equivalent to a UWB label device), and therefore whether the user stores the mobile phone at a specified position or not is judged.
By adopting the scheme, the non-electronic scheme of the existing mobile phone centralized bag can be adopted for mobile phone collection, at the moment, the entrance guard gate device needs to be arranged behind the mobile phone centralized bag when deployment is carried out, namely, a user firstly scans the mobile phone and then inputs a face image, if the user has permission to enter, UWB positioning data of the mobile phone is obtained, and when the user places the mobile phone into the mobile phone centralized bag, the entrance guard control device enables the entrance guard gate device to open the entrance guard so that the user can enter.
As a simplified scheme, in some application scenarios without access control management, the system may only have: the Bluetooth interaction device, the UWB positioning device and the access control device are mainly used for enabling students to sign in through real-name authentication and placing mobile phones at specified positions. Namely, through Bluetooth interaction, the user authentication of face recognition is carried out by using the own mobile phone of the user, and then UWB positioning is carried out to judge whether the user stores the mobile phone in a designated position area or not.
And centimeter-level position judgment can be realized by adopting UWB positioning, so that the monitoring of mobile phone collection is realized.
As an extended technical solution, a millimeter wave imaging device may be used to determine whether the user still carries an additional mobile phone.
As shown in fig. 2, compared to the embodiment shown in fig. 1, the access control system is additionally provided with a face acquisition device and a mobile phone temporary storage device.

The mobile phone temporary storage device is used for providing a space for storing the mobile phone of the user.
The scheme shown in fig. 1 requires real-name verification by a mobile phone of a user, and after the user passes authentication for the first time, the access control device can actually acquire mobile phone related data, so that when verification is performed later, the user only needs to scan a code by using the mobile phone, namely, UWB positioning can be activated by scanning the code at the moment. At the moment, the entrance guard device can be provided with the face acquisition device, so that a user does not need to carry out face recognition through a mobile phone, or the user passes through the entrance guard device when the user does not have the mobile phone at all.
In the scheme shown in fig. 2, when the user passes through the access control device, if the UWB positioning function is turned on, the UWB positioning device of the access control device actively starts to position the mobile phone of the user only by face recognition, and the user may not operate the mobile phone (at this time, bluetooth communication may be turned off). If UWB locate function is closed, then entrance guard control device control human-computer interaction device display information, suggestion user opens UWB locate function, and as preferred scheme, entrance guard control device can make human-computer interaction device show developments two-dimensional code, and the user only need can open UWB locate function through sweeping the sign indicating number.
As shown in the embodiment of fig. 3, compared with the embodiment of fig. 2, the access control device can send data to the cloud server through wireless or wired communication, so that the cloud server performs big data operation, and an artificial neural network can be constructed on the cloud server. The artificial neural network can be used for training and constructing a data model through a large amount of data, so that the behavior of a user is analyzed according to the position data of the mobile phone.
As shown in fig. 4, as a specific solution, the access control device provided by the present application is provided with: camera, touch-sensitive screen, physical keyboard and railing. The camera is used for collecting images, including human face images, health codes and the like of the user. The touch screen is used for realizing human-computer interaction. The barrier can realize the functions of the gate by rotating or stretching.
Particularly, the entrance guard device is further provided with a plurality of placing grooves for placing the mobile phone, the placing grooves are used for helping the user to temporarily store the mobile phone, as an optimal scheme, the placing grooves are provided with movable groove doors, and the groove doors are opened only after the user enters a password or face recognition before returning to the entrance guard device, so that the user can take back the mobile phone, and the safety of the mobile phone is ensured.
As shown in fig. 5, as another specific solution, a mobile phone temporary storage device may also be separately provided, and is provided with a camera, a touch screen, and a storage bin. Here the camera and touch screen arrangement is similar to that shown in figure 4, but they are only used to access the handset. A position switch is arranged in the storage bin, and if the mobile phone is stored, a signal generated by the position switch is sent to the entrance guard control device, so that the mobile phone storage management can be realized.
As another specific solution, the monitoring device of the present application may be configured as a monitoring probe with a pan/tilt head, which is installed in an entrance gate or other locations where the user can be monitored. Specifically, the monitoring device includes an optical camera and a millimeter wave camera. Which are used to acquire different image data, respectively.
