Description

Technical Field

[0001] This invention relates to the field of surveillance equipment, and more particularly to an intelligent camera with multi-scene mode switching. Background Technology

[0002] The underground parking garage is equipped with surveillance cameras specifically designed for monitoring the entrance and exit areas. These cameras monitor vehicles entering and exiting the garage in real time. When a vehicle enters the garage without turning off its high beams, the strong light from the high beams shines directly onto the surveillance camera, causing a sharp decline in image quality. This results in the loss of key visual information, automatic exposure imbalance, failure of infrared illumination, and accelerated hardware aging. Consequently, it affects the garage's core functions such as security management and parking guidance. Due to the poor lighting conditions inside the underground parking garage, the environment is dim. When people suddenly emerge from the blind spots of vehicles, the stark contrast between the strong light from the high beams and the dim lighting causes temporary vision impairment. During this time, people may be unable to discern the correct direction to avoid vehicles, greatly increasing the risk of traffic accidents. Summary of the Invention

[0003] To overcome the drawback that the strong light from a vehicle's high beams can severely interfere with surveillance cameras and pose a safety threat to people inside an underground parking garage when the vehicle enters directly without turning off its high beams, this invention provides a smart camera with multi-scene mode switching.

A rotary motor is installed on the top, driving the housing to rotate vertically; a rotating ring is rotatably connected to the housing; a gear ring is fixed to the rotating ring; a drive motor is installed on the housing; a gear is fixed to the output shaft of the drive motor; the gear meshes with the gear ring; a surveillance camera facing the entrance area of ​​the underground garage is installed at the bottom of the housing; a transparent protective cover for the surveillance camera is fixed to the rotating ring; an anti-glare inner film is affixed to the rear side of the transparent protective cover; a bracket is fixed to the rotating ring; a wide-angle convex mirror using polarized lenses is fixed to the front side of the bracket.

[0005] As a preferred embodiment of the present invention, an anti-glare outer film is attached to the left and right sides of the wide-angle convex mirror.

[0006] As a preferred embodiment of the present invention, an electronic signboard is installed on the rear side of the hanger.

[0013] As a preferred embodiment of the present invention, a loudspeaker is installed at the bottom of the mounting block.

[0014] This invention discloses a smart camera with multi-scene mode switching. The camera is mounted on a lifting frame via a rotatable housing, and a wide-angle convex mirror is positioned below it. This mirror immediately reduces and reflects the strong light emitted by a vehicle's high beams towards the driver, alerting them to the need to turn off the high beams. If the driver is unaware of the need to turn off the high beams, a rotating ring causes an anti-glare inner membrane within the transparent housing to shield the camera, reducing interference from the high beams. Simultaneously, the rotating ring rotates the wide-angle convex mirror and an electronic signboard, swapping their positions to prevent the mirror from reflecting light and interfering with the driver's vision. The electronic signboard, along with flashing warning lights and a loudspeaker, continues to remind the driver to turn off the high beams.

[0015] This invention provides a smart camera with multi-scene mode switching, which solves the following technical problem: when a vehicle enters an underground parking garage without turning off its high beams, its strong light will seriously interfere with the monitoring camera and threaten the safety of people staying in the garage.

Detailed Implementation

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0023] Example 1: A smart camera with multi-scene mode switching, such as Figures 1-5As shown, the system includes a fixed frame 11, a lifting frame 12, an electric winding machine 13, a lifting rope 14, a cover 21, a rotary motor 22, a rotating ring 23, a gear ring 24, a drive motor 25, a gear 26, a hanging bracket 27, a monitoring camera 3, a transparent protective cover 4, an anti-glare inner film 41, a wide-angle convex mirror 5, and an anti-glare outer film 51. The lifting frame 12 is slidably connected to the fixed frame 11. The electric winding machine 13 is mounted on the fixed frame 11. The lifting rope 14 is wound around the winding shaft of the electric winding machine 13. The lower end of the lifting rope 14 is fixedly connected to the lifting frame 12. The cover 21 is rotatably connected to the lifting frame 12. The rotary motor 22 is mounted on the lifting frame 12. The output shaft of the rotary motor 22 is fixedly connected to the cover 21. The rotating ring 23 is rotatably connected to the cover 21. The gear ring 24 is fixedly connected to the rotating ring 23. The drive motor 25 is mounted on the cover 21. The output shaft of the drive motor 25... A gear 26 is fixedly connected to the shaft; the gear 26 meshes with the gear ring 24; a monitoring camera 3 is installed at the bottom of the cover 21; a transparent cover 4 is fixedly connected to the rotating ring 23, and the transparent cover 4 covers the outside of the monitoring camera 3; an anti-glare inner film 41 is attached to the rear inner side of the transparent cover 4; a hanger 27 is fixedly connected to the rotating ring 23; a wide-angle convex mirror 5 is fixedly connected to the front side of the hanger 27, and the wide-angle convex mirror 5 uses a polarizing lens; an anti-glare outer film 51 is attached to the left and right sides of the wide-angle convex mirror 5. When the strong light of the vehicle's high beam shines on the left and right sides of the wide-angle convex mirror 5, the left and right sides of the wide-angle convex mirror 5 will reflect the strong light towards the blind spots on the left and right sides of the underground garage. At the same time, the anti-glare outer film 51 can weaken the strong light reflected towards the blind spots on the left and right sides of the underground garage in time, so that people in the blind spots of the underground garage will not be directly hit by the reflected strong light.

[0024] like Figure 4 and Figure 5 As shown, an electronic signboard 6 is installed on the rear side of the hanger 27; two flashing warning lights 71 are installed on the rear side of the hanger 27; two supplementary lighting lights 72 are installed on the rear side of the hanger 27, with the two supplementary lighting lights 72 located on the left and right sides of the electronic signboard 6 respectively, and the supplementary lighting lights 72 are installed in an inclined state facing away from each other; a mounting block 81 is rotatably connected to the bottom of the hanger 27; a laser rangefinder 82 is installed on the front and rear sides of the mounting block 81; a counterweight is provided inside the mounting block 81; when the hanger 27 is flipped, the mounting block 81 can always remain vertical under the gravity of the counterweight, thereby keeping the laser rangefinders 82 on the front and rear sides of the mounting block 81 in a laser ranging working state parallel to the ground.

[0025] This invention discloses a multi-scene mode switching intelligent camera. The monitoring camera 3 is installed on the ceiling of an underground parking garage, with its shooting direction facing the entrance and exit area of ​​the garage. A wide-angle convex mirror 5 also faces the entrance and exit area. An electronic signboard 6 faces away from the entrance and exit area and initially displays a warning message about yielding to pedestrians. When a vehicle enters the underground garage without turning off its high beams, the monitoring camera 3 intelligently identifies the on / off status of the vehicle's high beams based on the intensity of the headlights. When the strong light from the high beams shines on the wide-angle convex mirror 5, the polarizing film on the mirror filters the scattered light, reducing the intensity of the reflected light. The wide-angle convex mirror 5 reflects the strong light from the high beams towards the driver in a weaker light state, allowing the driver to promptly observe that the high beams are on and realize the need to turn them off. The reflected weak light only serves as a warning to the driver and does not affect their field of vision.

[0026] If the driver fails to turn off the high beams after receiving a light warning, the drive motor 25 drives the gear 26 to rotate. The gear 26 meshes with the gear ring 24, causing the rotating ring 23 to rotate 180 degrees. This rotating ring 23 then rotates the transparent cover 4, positioning the anti-glare inner film 41 directly in front of the lens of the monitoring camera 3. The strong light from the vehicle's high beams is weakened by the anti-glare inner film 41, reducing interference to the monitoring camera 3. Simultaneously, the rotating ring 23 rotates the bracket 27 180 degrees, causing the wide-angle convex mirror 5 on the front of the bracket 27 to rotate backward, facing away from the entrance / exit of the underground parking garage. To prevent the wide-angle convex mirror 5 from continuing to reflect light and interfere with the driver's normal observation, the electronic signboard 6, flashing warning light 71, and supplementary lighting 72 on the rear side of the hanger 27 are rotated forward to face the entrance and exit area of ​​the underground garage. At this time, the electronic signboard 6 switches to display the warning message "Please turn off your high beams," and the flashing warning light 71 flashes briefly at the driver to attract the driver's attention to the direction of the flashing warning light 71, so that the driver can see the warning message displayed on the electronic signboard 6 in time and continue to remind the driver to turn off the high beams.

[0027] If the driver does not realize the need to turn off the high beams after a brief flashing warning light 71 and continues driving forward, the rotary motor 22 drives the housing 21 and its connected monitoring camera 3 to continuously rotate downwards and forwards. This allows the monitoring camera 3 to continuously adjust its downward shooting angle to follow the oncoming vehicles, enabling it to continuously capture images of vehicles with their high beams on. Simultaneously, the electronic signboard 6 and the flashing warning light 71 rotate downwards and forwards along with the housing 21, ensuring they are always facing the driver to remind them to turn off their high beams. At the same time, the electric rewinder 13 releases the lifting rope 14 downwards a short distance, causing the lifting frame 12 to move the housing 21 and its connected high beams downwards. The connected monitoring camera 3, electronic signboard 6, and flashing warning light 71 are lowered a short distance to lower the height of the electronic signboard 6 and flashing warning light 71, so that they are in a lower area to remind vehicles to turn off their high beams. At this time, the laser rangefinders 82 on the front and rear sides measure distances to the front and rear sides respectively. The laser rangefinders 82 observe whether there are any tall vehicles traveling towards the gantry 27. If a laser rangefinder 82 observes a tall vehicle traveling towards the gantry 27, the laser rangefinder 82 quickly sends a take-up command to the electric rewinder 13 through the circuit system, so that the electric rewinder 13 drives the lifting rope 14 to raise the lifting frame 12 to its original position, so as to prevent tall vehicles from colliding with the gantry 27.

[0028] As the surveillance camera 3 continuously adjusts its downward shooting angle to follow the continuously moving vehicles, the supplementary lighting lamps 72 on both sides provide supplementary lighting to the left and right sides of the vehicle's direction of travel. This immediately increases the brightness of the lighting on the left and right sides of the vehicle's direction of travel, allowing the driver to immediately observe people in the garage who are coming from the blind spot. It also reduces the light difference between the vehicle's high beams and the dim environment of the garage, thereby alleviating the temporary decrease in vision caused by strong light shining directly into the eyes.

[0029] Example 2, as Figures 1-5As shown, based on Embodiment 1, a warning line projection light 73 is installed on the left and right sides of the hanger 27. When the monitoring camera 3 detects a vehicle approaching the entrance / exit area, the two warning line projection lights 73 on the hanger 27 project bright yellow warning lights to the left and right sides of the vehicle's direction of travel, respectively. The two warning lights are parallel to the vehicle's direction of travel and are projected onto the ground in front of the vehicle. As the rotating motor 22 controls the housing 21 to continuously rotate forward and downward, the housing 21 drives the monitoring camera 3 to track and photograph the vehicle traveling forward. At the same time, the housing 21 drives the two warning line projection lights 73 on the hanger 27 to continuously rotate forward and downward, keeping the two irradiated warning lights in front of the vehicle's direction of travel. At this time, if people in the underground parking garage see the moving bright yellow light strip on the ground, they will realize that a vehicle is approaching and can avoid it in time to prevent traffic accidents. After the vehicle leaves the monitoring range, the rotating motor 22 controls the housing 21 to return to the initial monitoring position.

[0030] Example 3, as Figures 1-5 As shown, based on Embodiment 1, a loudspeaker 9 is installed at the bottom of the mounting block 81. When the monitoring camera 3 detects a vehicle approaching the entrance / exit area, the loudspeaker 9 will broadcast warning voice messages in a loop, such as "Please turn off your high beams" and "Please give way to pedestrians." Through voice broadcasting, the driver of the approaching vehicle can be reminded to turn off his high beams, and people staying in the garage can be alerted to avoid oncoming vehicles.
