[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a smart parking lot sensor-based parking space occupancy detection device of the present invention includes a horizontal tube 1, a camera, and a sensor 9. One end of the horizontal tube 1 is bent downwards, and a flat wire 2 is provided inside the horizontal tube 1. One end of the flat wire 2 extends downwards from the bent end of the horizontal tube 1 and is fixedly connected to the camera. A protective shell 3 is installed on the outside of the camera. The other end of the flat wire 2 extends from the opening at the other end of the horizontal tube 1 and is equipped with a winding mechanism. A fixing frame 7 is installed on the outside of the winding mechanism. The other end of the fixing frame 7 is installed on the horizontal tube 1. A fixing shell 8 is installed on the end of the fixing frame 7 connected to the horizontal tube 1. The fixing shell 8 is installed on the outside of the horizontal tube 1 and the sensor 9 is installed on the fixing shell 8. A driving mechanism is installed on the other end of the fixing frame 7.

[0026] In this embodiment, the drive mechanism includes a first motor 14, a fixing ring 15, a support rod 16, a panel 13, and a collar 12. The collar 12 is mounted on the end of the fixing frame 7 away from the horizontal tube 1. The panel 13 is movably disposed inside the collar 12. A first bearing is embedded in the center of the panel 13. The first motor 14 is mounted on the panel 13. The shaft of the first motor 14 passes through the inner ring of the first bearing and is mounted on a shaft 10 through a coupling. The other end of the shaft 10 is mounted on the fixing frame 7 and fixed to one end of the horizontal tube 1. Multiple support rods 16 are mounted on the panel 13 in a ring structure. The fixing ring 15 is mounted on the other end of the support rods 16.

[0027] In this embodiment, the winding mechanism includes a second motor 17, a winding reel 6, a reel frame, and a drive shaft. The winding reel 6 is disposed inside the reel frame, and the reel frame is mounted on a fixed frame 7. The other end of the flat wire 2 is coiled in the winding reel 6. Second bearings 5 ​​are embedded in both sides of the reel frame. A drive shaft is installed in the center hole of the winding reel 6. Both ends of the drive shaft are installed in the inner rings of the second bearings 5. The second motor 17 is mounted on one side of the reel frame, and the rotating shaft of the second motor 17 is fixedly connected to the drive shaft.

[0028] The drive shaft has a hollow interior and a slip ring installed inside, allowing the core of the flat conductor to be mounted on the movable end of the slip ring, while another conductor can be connected to the fixed end of the slip ring, so that the rotation of the reel does not affect the conduction of the flat conductor.

[0029] In this embodiment, an annular groove 19 is provided on the outer ring surface of the panel 13, and a positioning ring is installed on the inner ring surface of the collar 12. The positioning ring is movably disposed in the annular groove 19, so that the fixing frame can only rotate around the positioning ring.

[0030] In this embodiment, a load-bearing bearing 11 is installed on the outside of the shaft 10. The outer ring of the load-bearing bearing 11 is installed on the fixing frame 7. The load-bearing bearing can better distribute the weight on the shaft, so that the device can be stably fixed above.

[0031] In this embodiment, the protective shell 3 is made of transparent plastic material, and a counterweight 18 is installed on the bottom surface of the protective shell 3 so that the camera can see the external situation through the protective shell.

[0032] In this embodiment, there are multiple sensors 9, namely ultrasonic sensors and infrared sensors. The ultrasonic sensors and infrared sensors are externally mounted with connecting brackets, and the other end of the connecting brackets is mounted on the fixed shell 8. The ultrasonic sensors, infrared sensors and cameras are all controlled by a microcontroller.

[0033] In this embodiment, the first motor 14 is a brake motor, and the second motor is also a brake motor. Therefore, after power is cut off, the horizontal tube and the winding reel can be positioned, preventing the horizontal tube and the winding reel from rotating on their own.

[0034] In this embodiment, the cross-section of the horizontal tube 1 is set in a flat structure and matches the cross-section of the flat wire 2, so that the flat wire can only enter and exit along the horizontal tube, avoiding the rotation of the flat wire and increasing stability.

[0035] In this embodiment, the fixing ring 15 has a ring-shaped structure with multiple fixing holes, and bolts can pass through the fixing holes to fix the device to the top of the indoor parking lot.

[0036] An ultrasonic sensor emits ultrasonic waves vertically downwards and calculates the distance by measuring the reflection time of the sound waves. If the reflection time becomes shorter (the distance decreases), it is determined that a vehicle is parked there.

[0037] Infrared sensors can detect the heat emitted by a vehicle's engine or body, ultrasonic sensors can detect the presence of a vehicle, infrared sensors can help distinguish between dynamic and static vehicles, and combined with cameras, cameras provide visual verification, and ultrasonic sensors reduce false alarms.

[0038] Furthermore, when a parking space is occupied, the brake motor can be activated. The activation of the brake motor drives the shaft, and the rotation of the shaft drives the horizontal tube and the winding mechanism. The rotation of the horizontal tube drives the flat wire and the camera, allowing the camera to move above the vehicle's license plate.

[0039] After the second motor is started, it drives the drive shaft and the take-up reel. The rotation of the take-up reel releases the flat wire, and the counterweight pulls down the protective shell and the flat wire until the protective shell and the camera inside move to the side of the license plate. This allows for clear imaging and uploading of the image, enabling staff to move the vehicle, greatly increasing adaptability.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
