Description

Technical Field

[0001] This utility model relates to the field of security monitoring technology, specifically to a monitor with video projection function. Background Technology

[0002] Current surveillance systems are integrated with the Skynet surveillance system and equipped with relatively mature intelligent visual AI algorithms. They can perform structured calculations on real-time images captured by surveillance cameras, enabling facial recognition and analysis of abnormal behaviors such as crowd gatherings and illegal crossings. The analysis results are then sent to the dispatch center. However, these systems have drawbacks: limited police resources, long distances, and the sudden onset and rapid end of abnormal behaviors can prevent timely arrival at the scene, hindering intervention, deterrence, and dispersal, potentially leading to safety incidents. Therefore, a monitor with video projection capabilities is needed to intervene and deter abnormal behavior promptly, reducing the waste of police resources. Utility Model Content

[0003] The purpose of this invention is to provide a monitor with video projection function, which can project video in a timely manner to intervene and deter abnormal behavior when it is detected and to reduce the waste of police resources.

[0004] To achieve the above objectives, a monitor with video projection function is provided, including an electrically controlled rotating platform and a controller. The electrically controlled rotating platform is mounted on a pole and includes a projection component, a camera component, and a speaker. The platform drives the projection component, camera component, and speaker to rotate horizontally. The projection component includes a housing, within which a projector, a zoom adjustment motor, and a laser rangefinder are housed. The zoom adjustment motor adjusts the focal length by rotating the zoom ring of the projector via a rotating block mounted on its output shaft. The housing of the projection component is rotatably connected to the electrically controlled rotating platform via a rotating shaft. A flip motor that drives the rotating shaft is located inside the electrically controlled rotating platform. The electrically controlled rotating platform, camera, flip motor, projector, zoom adjustment motor, laser rangefinder, and speaker are all electrically connected to the controller.

[0005] Furthermore, it also includes a communication module, which is electrically connected to the controller to enable communication with the control center and transmission of image data that needs to be projected by the projection component.

[0006] Furthermore, the communication module is a wired communication module or a wireless communication module, or a combination of a wired communication module and a wireless communication module.

[0007] Furthermore, both the zoom adjustment motor and the tilting motor are stepper motors.

[0008] Furthermore, it also includes a storage module for storing image data projected by the projection component.

[0009] Principles and advantages:

[0010] 1. The electrically controlled rotating platform is used for multi-angle horizontal turning, enabling cameras connected to the Skynet surveillance system to detect abnormal behaviors such as crowd gatherings, fights, and illegal crossings from multiple angles. When such abnormal behaviors are detected, officers at the control center can intervene and deter those engaging in such behaviors in a timely manner through video projection and voice announcements, addressing the problem at its source. This reduces the number of police dispatches and saves police resources.

[0011] 2. This solution utilizes a rotating shaft and a flip motor to allow the projection assembly to rotate vertically, enabling the video to be projected onto the desired location in conjunction with an electrically controlled rotating platform. A laser rangefinder is used to calculate the projection distance, assisting in subsequent zoom adjustment. The zoom adjustment motor, via a rotating block on its output shaft, rotates the projector's zoom ring to adjust the focus, allowing control center personnel to manually adjust the projection clarity.

[0012] 3. The communication module allows for rapid transmission of videos to be projected, making the projected video unrestricted. Combined with the storage module, it allows for convenient and quick retrieval when needed, achieving the desired effect. Attached Figure Description

[0017] Example

[0018] A monitor with video projection capabilities, basically as follows: Figure 1 , Figure 2As shown, the system includes an electrically controlled rotating platform 1 and a controller. The electrically controlled rotating platform 1 is mounted on a pole and houses a projection component 6, a camera component 3, and a speaker 2. The electrically controlled rotating platform 1 is used to drive the projection component 6, camera component 3, and speaker 2 to rotate horizontally. The projection component 6 includes a housing containing a projector 7, a zoom adjustment motor, and a laser rangefinder 8. The zoom adjustment motor adjusts the focal length by rotating the zoom ring of the projector 7 via a rotating block 5 mounted on its output shaft. The housing of the projection component 6 is rotatably connected to the electrically controlled rotating platform 1 via a rotating shaft. The electrically controlled rotating platform 1 contains a flip motor 4 that drives the rotating shaft. The electrically controlled rotating platform 1, camera component 3, flip motor 4, projector 7, zoom adjustment motor, laser rangefinder 8, and speaker 2 are all electrically connected to the controller. The camera component 3 is a camera and needs to be connected to the SkyNet system.

[0019] The communication module is electrically connected to the controller and communicatively connected to the control center, used to transmit image data to be projected by the projection component 6. The communication module can be a wired communication module, a wireless communication module, or a combination of both. In this embodiment, a 4G communication module is used. The 4G communication module allows for rapid transmission of the video to be projected, making the projected video unrestricted.

[0020] The storage module stores image data projected by the projection component 6. The zoom adjustment motor and the tilt motor 4 are both conventional stepper motors. The electrically controlled rotating platform 1 is a conventional rotating platform. The controller is a conventional microcontroller controller, such as an ESP32 series microcontroller, which is compact and functional. The projector 7 is a conventional projector that can automatically adjust its focus, and the focus can also be adjusted manually by adjusting the zoom ring. In this solution, a zoom adjustment motor and a rotating block 5 are used instead. The camera is a conventional camera, and the laser rangefinder 8 and the speaker 2 are also of conventional types.

[0021] The electrically controlled rotating platform 1 in this solution can rotate horizontally at multiple angles, enabling cameras connected to the Skynet surveillance system to detect abnormal behaviors such as crowd gatherings, fights, and illegal crossings from multiple angles. When such abnormal behaviors are detected, officers at the control center can intervene and deter those engaging in such behaviors in a timely manner through video projection and voice announcements, addressing the problem at its source. This reduces the number of police dispatches and saves police resources.

[0022] This solution uses a rotating shaft and a flip motor 4 to flip the projection component 6 up and down, allowing the video to be projected onto the desired location in conjunction with the electrically controlled rotating platform 1. A laser rangefinder 8 is used to calculate the projection distance, providing a reference for operators to adjust the zoom. The zoom adjustment motor can rotate the zoom ring of the projector 7 via a rotating block 5 on its output shaft to adjust the focal length, enabling control center personnel to remotely adjust the projection clarity in the event of autofocus failure.
