[0002] Intelligent buildings are the product of the culmination of modern science and technology. Their technical foundation is mainly composed of modern construction technology, modern computer technology, modern communication technology and modern control technology, thus providing users with an efficient, comfortable, convenient and humanized building environment. Among them, face recognition devices are applied to intelligent buildings, which greatly improves the safety of buildings. Face recognition devices are based on advanced face recognition technology. They use cameras or cameras to collect images or video streams containing faces, and automatically detect faces in images, and then perform a series of related technologies on the detected faces for face recognition.

[0003] In traditional technology, a set of identification screens are installed on the gate machine, and residents are identified and allowed to enter through cameras. This operation is convenient and quick, but its fixed installation method results in a smaller recognition range. When a child's height cannot be captured by the camera, he or she cannot enter the interior of the area. At the same time, people are required to stand inside the designated area for identification, which reduces practicality.

[0004] Therefore, it is particularly important to improve the existing intelligent building face recognition device, design a new intelligent building face recognition device to solve the above-mentioned technical defects, and improve the practicality of the overall intelligent building face recognition device.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0025] An intelligent building face recognition device comprises a gate 1, a barrier rod 2 is installed on the outside of the gate 1, an identification screen 3 is installed on the top of the gate 1, an infrared sensor and a camera are arranged at the bottom of the identification screen 3, a frame 4 is installed at the bottom of the identification screen 3, a linkage shaft 5 is installed at the bottom of the frame 4, and a swing component 6 is installed at the bottom of the linkage shaft 5;

[0026] The swing assembly 6 is used to adjust the direction and angle of the identification screen 3 .

[0027] For further information, see Figure 1 , Figure 2 , Figure 3 and Figure 4In this embodiment, the swing assembly 6 includes a rotating shaft 601, a guide groove 602, a special-shaped disc 603, a connecting rod 604, a clamping rod 605 and a rotating roller 606. The rotating shaft 601 is installed on the outside of the linkage shaft 5, the guide groove 602 is opened on the surface of the rotating shaft 601, the special-shaped disc 603 is installed inside the gate machine 1 and is located on the back of the rotating shaft 601, the connecting rod 604 is installed inside the special-shaped disc 603, the clamping rod 605 is installed on the end of the connecting rod 604 away from the special-shaped disc 603, and the rotating roller 606 is installed on the side of the special-shaped disc 603 away from the connecting rod 604. The purpose of the face recognition device is to prevent outsiders from entering the interior of a specific area, collect face information through a camera, and recognize information through the recognition screen 3. The barrier rod 2 is pushed to enter the specific area. When a child appears, his / her height is much lower than the recognition screen 3. The camera cannot capture the face of the child and cannot open the barrier rod 2. The infrared sensor captures the height of the child, so that the motor drives the special-shaped disk 603 to rotate, and the connecting rod 604 slides inside the special-shaped disk 603. When the connecting rod 604 slides to the highest point inside the special-shaped disk 603, the connecting rod 604 tilts, and the connecting rod 604 drives the clamping rod 605 to swing downward, so that the linkage shaft 5 descends inside the rotating shaft 601, and the recognition screen 3 completes the descending work, so as to adapt to people of different heights.

[0028] Among them, see Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, a special-shaped groove 607 is opened inside the special-shaped disk 603, and a special-shaped block 608 is installed in the middle of the special-shaped disk 603. A guide rod is installed at one end of the connecting rod 604 close to the special-shaped disk 603. The connecting rod 604 is connected to the special-shaped groove 607 through the guide rod. A support rod 609 is installed between the connecting rod 604 and the clamping rod 605. Through the rotation of the special-shaped disk 603, the guide rod can move in contact with the inside of the special-shaped groove 607. When the guide rod contacts the highest point of the special-shaped groove 607, the connecting rod 604 is tilted at an angle. Through the design of the support rod 609, the linkage between the connecting rod 604 and the clamping rod 605 is achieved.

[0029] For further information, see Figure 1 , Figure 2 , Figure 3 and Figure 4In this embodiment, the linkage shaft 5 extends to the outside of the rotating shaft 601, and an anti-slip sleeve is installed at the bottom end of the linkage shaft 5. The clamping rod 605 is connected to the linkage shaft 5 through the anti-slip sleeve. The top and bottom of the rotating shaft 601 are both installed with limit plates 610. The inside of the limit plates 610 is symmetrically provided with empty grooves 611. An extension rod 612 is installed in the middle of the special-shaped block 608. An expansion rod 613 is installed on the side of the extension rod 612 away from the special-shaped block 608. An arc-shaped piece 614 is installed on the end away from the expansion rod 613. By rotating the special-shaped disk 603, the extension rod 612 is driven to move with the special-shaped disk 603, so that the rotating roller 606 can rotate. When the rotating roller 606 is in a horizontal state, it will enter the inside of the guide groove 602, thereby driving the rotating shaft 601 to rotate. When the rotating roller 606 is in a vertical state, the rotating shaft 601 will stop rotating, and the unfolding rod 613 will drive the arc piece 614 to be stuck in the inside of the empty groove 611, and limit the limiting piece 610, so as to complete the stopping of the rotation of the rotating shaft 601.

[0030] For further information, see Figure 1 and Figure 2 In this embodiment, a protective cover 7 is installed at the top of the front side of the identification screen 3. The protective cover 7 has an arc-shaped structure. The design of the protective cover 7 can effectively prevent the identification screen 3 from being damaged by high temperature or rainy weather, thereby shortening the service life of the identification screen 3.

[0031] In this embodiment, the implementation scenario is specifically as follows: the purpose of the face recognition device is to prevent outsiders from entering the interior of a specific area. The face information is collected through the camera, and the information is recognized through the recognition screen 3, so that the barrier rod 2 is contacted and fixed, and the barrier rod 2 is pushed to enter the interior of the specific area. When a child appears, his height is much lower than the recognition screen 3, and the camera cannot collect the face and the barrier rod 2 cannot be opened. The infrared sensor captures the height of the person, so that the motor drives the special-shaped disk 603 to rotate, and the connecting rod 604 slides inside the special-shaped disk 603. When the connecting rod 604 slides to the highest point inside the special-shaped disk 603, the connection rod 604 is realized. The connecting rod 604 is tilted, and at the same time, the connecting rod 604 drives the clamping rod 605 to swing downward, so that the linkage shaft 5 is lowered inside the rotating shaft 601, and the identification screen 3 is lowered to adapt to people of different heights. The rotation of the special-shaped disk 603 drives the extension rod 612 to move with the special-shaped disk 603, so that the rotating roller 606 rotates. When the rotating roller 606 is in a horizontal state, it will enter the inside of the guide groove 602, thereby driving the rotating shaft 601 to rotate, and the identification screen 3 is rotated, thereby avoiding the need for people to stand inside the designated area to perform face recognition, which greatly improves practicality.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
