Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figure 1 , the embodiment of the present utility model first provides a visual control system 200 for an elevator, including a visual recognition device 100, a cloud module 201, an induction module 202, an audio module 203, and a control module 204, specifically as follows:

[0032] The visual recognition device 100 is arranged on the inner wall of the elevator, and its function is to obtain real-time images for face recognition or other object recognition.

[0033] The cloud module 201 includes a first wireless module 2011, such as a 4G / 5G module or other wireless communication modules. The first wireless module 2011 can establish a connection wirelessly to realize data upload and download.

[0034] The induction module 202 can be a laser induction module or an infrared induction module, which is set at the elevator entrance and electrically connected to the control module 204, and is used to trigger the vision recognition device 100 to perform image recognition through the control module 204. Specifically, when a person or an object approaches the elevator entrance, the induction module 202 will trigger a signal, and this signal is transmitted to the control module 204 through electrical connection; after receiving the signal, the control module 204 will further process and trigger the vision recognition device 100 to start working. The vision recognition device 100 will capture real-time images, especially face recognition. And compare with the pre-stored images or data to identify people or objects for verification. In this way, the combined use of the induction module 202 and the control module 204 can provide an automated triggering mechanism, so that when a person or an object approaches the elevator, the system will automatically start and perform face recognition. This integration makes the access control of the elevator more efficient and secure, while saving the computing power and power consumption of the vision recognition device 100 and avoiding being in the detection state for a long time.

[0035] The audio module 203 is set inside the elevator to provide voice communication functions, such as communicating with the cloud module 201 or mobile terminals, the background, and the audio output of the broadcast inside the elevator, etc.

[0036] The control module 204 is electrically connected to the vision recognition device 100 and the audio module 203 respectively, and includes a second wireless module 2041. The second wireless module 2041 and the first wireless module 2011 both use the same wireless protocol to achieve communication connection. Among them, the vision recognition device 100 can respond to the induction module 202 and start acquiring real-time images. The control module 204 receives the real-time images, uploads the real-time images to the cloud module 201, and controls the elevator according to the real-time images at the same time.

[0037] The working process of the entire vision control system 200 is as follows;

[0038] Step S1: When a person or an object approaches the elevator entrance, the induction module 202 detects a signal and triggers the vision recognition device 100 to start working through the control module 204;

[0039] Step S2: The vision recognition device 100 captures real-time images and sends them to the control module 204;

[0040] Step S3: After receiving the real-time images, the control module 204 uploads them to the cloud module 201 for storage;

[0041] Step S4: The control module 204 or the cloud module 201 decides the actions of the elevator according to the received real-time images, such as allowing or rejecting users to enter the elevator, or automatically selecting a specific floor according to user information, etc.

[0042] Meanwhile, the audio module 203 can provide communication functions inside the elevator, such as connections to the outside or notifications inside the elevator.

[0043] In summary, the vision control system 200 provided by the first embodiment of the present utility model improves the usage experience, safety, and efficiency of the elevator, while facilitating management and maintenance. Exemplary application scenarios are as follows:

[0044] When an illegal entry into the elevator occurs (such as an electric vehicle or an illegal visitor entering the elevator), the induction module 202 in the vision control system 200 responds, driving the vision recognition device 100 to collect real-time images and uploading the real-time images to the cloud module 201 for comparison to determine the illegal entry; thereby sending corresponding instructions to the control module 204, and the control module 204 issues a closing instruction. At this time, the audio module 203 conducts voice prompt broadcasts, emitting voice prompts such as prohibiting elevator rides, and at the same time controls the elevator to be unable to close and unable to run to any floor.

[0045] After a legitimate visitor enters the elevator, the induction module 202 triggers the vision recognition device 100 to work. The visitor uses face recognition or holds a legitimate QR code (generated in advance by downloading a mini-program by authorized visitors) and aligns it with the vision recognition device 100 for recognition, and uploads the collected face image or QR code information to the cloud module 201 for comparison to determine the current legitimate entry, and transmits the corresponding instructions to the control module 204, and the elevator can delay closing the door. At the same time, the audio module 203 conducts voice prompt broadcasts, emitting voice prompts such as welcome to take the elevator, and the visitor can press the button to take the elevator to the corresponding floor or go to the corresponding floor automatically according to the permissions.

[0046] Through the combination of the vision recognition device 100, the cloud module 201, the induction module 202, the audio module 203, and the control module 204, the intelligent control of the elevator is realized, providing a more efficient, safe, convenient, and energy-saving elevator control operation mode.

[0047] Such as Figure 2 , in one embodiment, based on the above vision control system 200, the vision recognition device 100 is as Figure 2 shown. The vision recognition device 100 includes two parts: a camera 12 and a panel mechanism 11. Among them, the camera 12 is arranged at a wide-angle installation location of the elevator (such as the top), and the camera 12 is used for preliminary image recognition when triggered by the induction module 202 to avoid illegal entry; the panel mechanism 11 can be integrated on the inner side of the elevator door or the operation panel inside the elevator, and it is built-in with a micro camera, and users can perform operations such as face recognition, card swiping, or QR code scanning through the panel mechanism.

[0048] It is understandable that the camera 12 is mainly responsible for image acquisition and preliminary image recognition, such as detecting illegal entry. The panel mechanism 11, on the other hand, focuses more on user interaction, such as identity verification operations like face recognition, card swiping, or QR code scanning. The combination of the two can better realize the system functions. At the same time, the cooperation of the two cameras can better monitor illegal behaviors and avoid illegal operations of users in the elevator, such as deliberately blocking the panel mechanism 11, etc.

[0049] Refer to Figures 3 to 5 , as a preferred embodiment of the panel mechanism 11, the panel mechanism 11 includes a support and installation component 1 connected to the elevator. The support and installation component 1 is connected with a lifting and adjusting component 2, and a face recognition component 3 is rotatably connected to the lifting and adjusting component 2. The designs of the support and installation component 1 and the lifting and adjusting component 2 allow the panel mechanism 11 to be flexibly installed and adjusted. Adaptive installation can be carried out according to the specific structure and space requirements of the elevator.

[0050] Further refer to Figure 6 and Figure 7 , specifically, the support and installation component 1 includes a support vertical plate 101, and the support vertical plate 101 is used to be fixed at the inner wall of the elevator and installed in a concealed manner. The support vertical plate 101 is hollow and is provided with a plug hole 102 in the height direction to facilitate the bolt to pass through for firm connection. A strip-shaped barrel groove 103 is opened on the front side of the support vertical plate 101, and the lifting and adjusting component 2 is slidably connected to the strip-shaped barrel groove 103, so that the lifting and adjusting component 2 can move along the support and installation component 1 in the height direction, and the face recognition component 3 can rotate relatively, realizing precise adjustment of the face recognition component 3. This enables the face recognition component 3 to be conveniently installed at an angle and position more in line with ergonomics when the panel mechanism 11 is installed in elevators of different specifications, ensuring the accuracy and efficiency of recognition and simplifying the installation and adjustment process.

[0051] Furthermore, refer to Figure 7 , the lifting and adjusting component 2 includes a lifting and adjusting column 201 adapted to the plug hole 102. The lifting and adjusting column 201 is inserted into the interior of the plug hole 102, and the lifting and adjusting column 201 is used in cooperation with the plug hole 102. A threaded column 202 is fixedly installed on the front side of the bottom end of the lifting and adjusting column 201. The threaded column 202 passes through the strip-shaped barrel groove 103, and a limit nut 203 is threadedly sleeved on the outer side of the end of the threaded column 202 passing through the strip-shaped barrel groove 103. The rear side of the limit nut 203 forms extrusion with the front side of the support vertical plate 101 to fix the lifting and adjusting component 2, and the height of the face recognition component 3 is adjusted and positioned through the limit nut 203.

[0052] In a further aspect of the embodiment of the present utility model, a card-swiper plate 104 is fixedly installed at the top of the front side of the support vertical plate 101, enabling users to conveniently perform card-swiper operations. This design simplifies the user operation process and improves the efficiency of identity verification.

[0053] Further, the rear side surface of the limit nut 203 is designed to be rough to improve the connection stability.

[0054] Furthermore, reference can be made to Figures 6 to 9 , a support carrier plate 204 is fixedly installed at the top of the lifting adjustment column 201, a vertical column 205 is fixedly installed at the top of the support carrier plate 204, a connecting plate 206 is fixedly installed at the top of the vertical column 205, two symmetrically arranged rotating connection seats 207 are fixedly installed on the front side of the connecting plate 206, a U-shaped frame 208 is fixedly installed on the back of the connecting plate 206, a through column 209 passes through the inside of the U-shaped frame 208, the front end of the through column 209 passes through the connecting plate 206, an annular baffle 210 is fixedly sleeved in the middle of the through column 209, the annular baffle 210 is located inside the U-shaped frame 208, a return spring 212 is sleeved on the outer side of the through column 209 and behind the annular baffle 210, a positioning column 211 is fixedly installed on the end surface of the through column 209 passing through the connecting plate 206, and a fixed pull ring 213 is fixedly installed at the rear end of the through column 209.

[0055] The face recognition component 3 includes an integrated panel 301, a rotating connection shaft 302 adapted to the rotating connection seat 207 is fixedly installed on the back of the integrated panel 301, the rotating connection shaft 302 is located between the two rotating connection seats 207, and the rotating connection shaft 302 is in rotational cooperation with the rotating connection seat 207. A plurality of positioning holes 303 adapted to the positioning column 211 are formed on the outer side of the rotating connection shaft 302, the positioning column 211 is inserted into the corresponding positioning hole 303, and the positioning column 211 and the positioning hole 303 are used in cooperation.

[0056] The installation principle of the panel mechanism 11 provided by the embodiment of the present utility model is as follows:

[0057] When it is necessary to install the panel mechanism 11 of the visual recognition device 100 provided by the embodiment of the present utility model inside the elevator, first, the staff loosens the limit nut 203, and then the lifting adjustment assembly 2 can be moved up and down. After the lifting adjustment assembly 2 is moved to an appropriate height, the limit nut 203 is tightened again, so as to realize the adjustment of the height of the lifting adjustment assembly 2 and the face recognition assembly 3. Additionally, by pulling the fixed pull ring 213 backward, at this time, the fixed pull ring 213 will drive the through column 209 and the positioning column 211 to move backward, and at the same time, the return spring 212 will contract and become shorter. At this time, the positioning column 211 will disengage from the inside of a positioning hole 303, and then the integrated panel 301 is rotated. After the integrated panel 301 is adjusted to an appropriate angle, the fixed pull ring 213 is released. At this time, due to the elastic force of the return spring 212, the positioning column 211 will be inserted into the inside of the corresponding other positioning hole 303, so as to realize the adjustment of the angle of the integrated panel 301. The present utility model can not only adjust the height of the face recognition assembly 3, but also adjust the tilt angle of the face recognition assembly 3, so as to make the face recognition effect better.
