[0002] Against the backdrop of rapid urbanization, electric vehicles have become the preferred mode of transportation for many citizens due to their convenience and environmental friendliness. However, with the surge in the number of electric vehicles, the phenomenon of them illegally entering elevators and charging on upper floors has become increasingly serious. This not only threatens the operational safety of elevators but also poses a serious fire safety hazard. To address this issue, elevator camera devices that actively identify electric vehicles have emerged, using advanced visual AI technology and intelligent recognition algorithms to achieve real-time monitoring and accurate identification of electric vehicles inside elevators.

[0003] However, in the existing technology, most of these elevator camera devices are fixed installations, and the shooting angle of the camera is often inconvenient to adjust. When shooting the interior environment of the elevator, such cameras may not be able to fully cover or accurately capture all the features of the electric vehicle. In particular, when the electric vehicle is located at the edge or corner of the camera's field of view, the recognition accuracy may be affected. Therefore, we need to propose an elevator camera device that can actively identify electric vehicles. Utility Model Content

[0004] The purpose of this invention is to provide an elevator camera device for actively identifying electric vehicles.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution:

[0023] An elevator camera device for actively identifying electric vehicles includes a positioning plate 1 and a camera body 6. A motor box 2 is fixedly installed at the bottom of the positioning plate 1, and a rotating rod 3 is rotatably installed at the bottom of the motor box 2. The top end of the rotating rod 3 passes through the motor box 2 and is connected to a first drive motor 4. A mounting base 5 is fixedly connected to the bottom end of the rotating rod 3. A power assembly 7 for swinging and adjusting the camera body 6 is provided inside the mounting base 5. The power assembly 7 includes a worm gear 701, one end of which is rotatably installed on the inner wall of one side of the mounting base 5, and the other end of which is connected to a second drive motor 702. A worm wheel 70 meshes with the bottom of the worm gear 701. 3. A rotating shaft 704 is fixedly inserted inside the worm gear 703. The two ends of the rotating shaft 704 are respectively rotatably mounted on the two side walls of the mounting base 5. By setting the positioning plate 1, motor box 2, rotating rod 3 and first drive motor 4, the camera body 6 can be horizontally rotated and adjusted, thereby increasing the shooting range of the camera body 6. In addition, by setting the power component 7 inside the mounting base 5, the camera body 6 can be swung and adjusted. Combined with the horizontal rotation adjustment, the shooting angle of the camera body 6 can be further increased to achieve full coverage of the elevator interior environment, which is conducive to further improving the recognition accuracy of electric vehicles.

[0024] By adopting the above cases, such as Figure 4As shown, it also includes a connecting frame 705. One end of the connecting frame 705 is fixedly installed on the outer wall of the rotating shaft 704, and the other end of the connecting frame 705 is fixedly connected to the camera body 6. The output shaft of the second drive motor 702 can drive the worm gear 701 to rotate in the forward or reverse direction, thereby driving the worm wheel 703 to rotate, which in turn drives the rotating shaft 704 to rotate. Thus, the connecting frame 705 can drive the camera body 6 to swing and adjust, thereby flexibly adjusting the shooting angle of the camera body 6 according to actual needs.

[0025] The outer wall of the mounting base 5 is provided with a sliding groove 8 that is adapted to the connecting frame 705. The connecting frame 705 is slidably connected to the inside of the sliding groove 8. By setting the sliding groove 8, the connecting frame 705 is limited, making its movement process more stable.

[0026] The second drive motor 702 is fixedly installed on the inner wall of one side of the mounting base 5. One end of the output shaft of the second drive motor 702 is fixedly connected to one end of the worm gear 701. The second drive motor 702 is set as a forward and reverse stepper motor. The stepper motor can achieve precise control of the motor by controlling the sequence, frequency and number of electrical pulses applied to the motor coil. This means that the camera body 6 can adjust the shooting angle more accurately, thereby ensuring the quality and stability of the shooting image.

[0027] The bottom of the positioning plate 1 has four sets of mounting holes 9, and the four sets of mounting holes 9 are symmetrically arranged. By using the positioning plate 1 and the mounting holes 9 together, the entire elevator camera device can be easily installed on the top of the elevator car.

[0028] The first drive motor 4 is fixedly installed at the bottom of the motor box 2. One end of the output shaft of the first drive motor 4 is fixedly connected to the top of the rotating rod 3. The first drive motor 4 is configured as a forward and reverse stepper motor.

[0029] The mounting base 5 has an internal cavity 11 and an arc-shaped part 10 at its bottom.

[0030] The camera body 6 acquires image data inside the elevator car and performs preprocessing on the acquired images to improve the accuracy and robustness of subsequent classification. Preprocessing includes operations such as denoising and image enhancement. The denoising operation uses a filter to remove noise from the image, and the image enhancement uses histogram equalization to enhance the contrast and brightness of the image.

[0031] Feature extraction is performed on the preprocessed image data to extract feature information related to people and vehicles. Deep learning methods are used to extract features. The YOLO model based on deep learning is adopted. By training a large amount of sample data, the network can learn target features related to people and non-motorized vehicles in the image.

[0032] The extracted features are classified and judged using a trained classifier, and the image data is divided into two categories: people and non-motorized vehicles. The deep learning algorithm uses the classic ResNet convolutional neural network, which is trained on large-scale data to enable the network to have good image classification capabilities.

[0033] Based on the classification algorithm's results, when both pedestrians and two-wheeled vehicles are detected inside the elevator, the algorithm outputs to the backend management center and the linked elevators, prohibiting the elevator doors from closing and its upward and downward movement. This algorithm employs an image recognition-based elevator pedestrian and vehicle classification algorithm, which has the following advantages compared to traditional methods: It uses image recognition technology to accurately classify people and two-wheeled vehicles inside the elevator; through preprocessing and feature extraction, the algorithm's robustness is improved, enabling it to adapt to classification requirements under different lighting and angle conditions; the algorithm uses a fast classification algorithm, enabling it to quickly and accurately determine whether there are people or two-wheeled vehicles inside the elevator in real-time scenarios; the classifier can be trained and updated as needed to adapt to different scenarios and changes.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
