Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle management technology, and more specifically, to a parking space vehicle presence sensing device. Background Technology
[0002] With rapid urbanization and a surge in car ownership, underground parking garages have become an indispensable urban parking facility. Efficient management of underground garages, improving parking space utilization, and accurately detecting vehicle occupancy are crucial. Currently, video parking space detection terminals using cameras are widely used for monitoring underground parking garages.
[0003] However, underground parking garages generally suffer from dim lighting. Video parking space detection terminals rely on good lighting to obtain clear images; in dim lighting, images are prone to blurring, noise, poor color reproduction, and significant shadow interference, leading to errors in parking space occupancy judgment and vehicle information recognition. To achieve intelligent and efficient management of underground parking garages, addressing the impact of dim lighting on parking space sensing equipment is urgently needed, as it is of great significance for improving the urban parking experience and resource utilization efficiency. Utility Model Content
[0004] In view of the problems existing in the prior art, this utility model proposes a parking space vehicle presence sensing device.
[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:
[0006] A vehicle presence sensing device for a parking space includes a video monitoring terminal and deceleration protrusions set on the front and rear boundary lines of the parking space. An installation groove is provided near the front and rear boundary lines of the parking space, and a glass plate is provided at the opening of the installation groove. A sensor light is installed in the installation groove, and a sensing system is provided in the deceleration protrusion. When a vehicle passes over the deceleration protrusion, the sensing system is triggered, thereby turning on the sensor light for 1 to 5 minutes.
[0007] When a vehicle prepares to enter or exit a parking space, it will pass over a speed bump positioned on the front or rear edge of the parking space. As the vehicle passes over the speed bump, it triggers a sensor system within it. Once triggered, the sensor system activates a sensor light within the mounting slot, providing adequate illumination for the video monitoring terminal. The sensor light remains on for 1 to 5 minutes, sufficient for the video monitoring terminal to acquire a clear image of the parking space and accurately identify parking space occupancy and vehicle information within this timeframe.
[0008] In dimly lit underground parking garages, motion-sensor lights provide additional, targeted illumination for video monitoring terminals, reducing issues such as image blur, noise, poor color reproduction, and shadow interference, thereby improving the accuracy of parking space monitoring. The motion-sensor lights only activate for 1-5 minutes when a vehicle passes a speed bump, avoiding prolonged and unnecessary lighting and saving energy.
[0009] Preferably, the deceleration protrusion includes a rubber skin and a mounting plate fixed to the ground. Two mounting plates are provided, and the two ends of the rubber skin are respectively fixed to the two mounting plates. The sensing system is located below the rubber skin.
[0010] When a vehicle passes over a speed bump, it crushes the rubber sheeting. The pressure causes the rubber sheeting to deform downwards, contacting a sensor system mounted on a plate below it. This triggers the sensor system, activating the motion-activated lights. The rubber sheeting's elasticity helps to cushion and absorb shocks when the vehicle passes over it, reducing vehicle bumps and impacts on the ground. By placing the sensor system under the rubber sheeting, it provides some protection, reducing direct damage from external factors and extending the system's lifespan.
[0011] Preferably, the sensing system includes a support plate and a micro switch disposed below the support plate, and also includes an elastic element. When no external force is applied, the elastic element pushes the support plate away from the micro switch and causes the center part of the rubber skin to move upward to form a protrusion.
[0012] Under normal conditions, the elastic element pushes the support plate upward, moving it away from the microswitch, while the center of the rubber skin bulges upward. When the vehicle passes over the deceleration bump and runs over the rubber skin, the rubber skin presses down, causing the support plate to move downward against the elastic force of the elastic element until it contacts and triggers the microswitch.
[0013] The elastic element acts as a buffer, reducing the impact force directly acting on the microswitch and extending its service life. After the vehicle leaves, the elastic element allows the support plate and rubber skin to return to their initial positions, preparing for the next trigger.
[0014] As a preferred embodiment, a sensing groove is provided on the ground, a micro switch is installed in the sensing groove, the elastic element is a spring, the upper end of the support plate extends to both sides to form an extension, one end of the spring is fixed to the lower end surface of the extension, and the other end is fixed to the ground.
[0015] Under normal circumstances, the spring pushes the extension of the support plate upwards, moving the support plate away from the microswitch in the sensing groove. At this time, the center of the rubber cover bulges upwards. When a vehicle runs over the rubber cover, the pressure causes the extension of the support plate to press down, compressing the spring. The support plate moves downwards and contacts the microswitch, thus triggering the sensor. Placing the microswitch within the sensing groove in the ground does not occupy extra space, making the overall structure more compact. The extension design increases the contact area between the support plate and the spring, making the spring support more stable and ensuring smooth triggering.
[0016] Preferably, positioning rods are provided at both ends of the induction groove, and positioning holes for the positioning rods are opened on the lower end face of the support plate. During the up and down movement of the support plate, the positioning rods are always in the positioning holes.
[0017] When a vehicle runs over the rubber sheeting, causing the support plate to move up and down, the positioning rods at both ends of the sensing groove remain inserted into the positioning holes on the lower end face of the support plate. The positioning rods slide within the positioning holes as the support plate moves, providing guidance and limiting for the up-and-down movement of the support plate.
[0018] Preferably, a shaping plate is fixed to the upper surface of the support plate, the cross-section of the shaping plate is semi-circular, and the arc surface of the shaping plate is set at the top.
[0019] When the rubber skin is run over by a vehicle, the pressure is transmitted to the shaping plate on the support plate. The shaping plate has a semi-circular cross-section with its curved surface facing upwards, which allows it to bear the pressure more evenly and transmit the pressure more effectively to the support plate, thereby triggering the micro switch.
[0020] Preferably, the bottom of the mounting groove is provided with an inclined surface that slopes toward the center of the parking space, and the sensor light is set on the inclined surface.
[0021] The inclined slope allows the light from the sensor lights to be more concentrated in the center of the parking space, reducing blind spots and improving lighting effect. Attached Figure Description

[0028] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.
[0029] Example
[0030] In this embodiment, the parking space vehicle presence sensing device includes a video parking space detection terminal. The video parking space detection terminal is usually composed of multiple cameras, an image acquisition and processing unit, a storage unit, a communication unit, etc. The cameras are installed reasonably according to the parking space layout and monitoring needs.
[0031] Image Acquisition and Processing Unit: Image Acquisition: The analog video signal acquired by the camera is transmitted to the image acquisition card via a video cable. The image acquisition card converts the analog signal into a digital signal for processing by the computer. In some network cameras, the image acquisition and digitization process is completed internally, and the digital image data is directly output through the network interface.
[0032] Image processing: Image processing is performed using dedicated image processing chips or by utilizing the computer's CPU or GPU. This mainly includes preprocessing operations such as image noise reduction, contrast enhancement, and color correction to improve image quality. Then, object detection algorithms, such as deep learning-based convolutional neural network algorithms, are used to identify and locate targets such as vehicles and parking spaces in the image, extracting feature information such as vehicle outlines, license plate numbers, and vehicle colors to determine whether a parking space is occupied.
[0033] like Figures 1-4 As shown, the parking space vehicle presence sensing device in this embodiment also includes a deceleration protrusion 110, a mounting groove 120, and an internal sensor light 1201 and related sensing and control components, all disposed on the front and rear boundary lines of the parking space.
[0034] The deceleration protrusion 110 includes a rubber skin 1101 and two mounting plates 1102 fixed to the ground. Both ends of the rubber skin 1101 are fixed to the two mounting plates 1102, and a sensing system is located below it. A sensing groove 150 is formed in the ground. The sensing system includes a microswitch 140 disposed within the sensing groove 150. Above the microswitch 140 is a support plate 130 connected to a spring 160 via an extension 1301. The other end of the spring 160 is fixed to the ground. Positioning rods 1501 are provided at both ends of the sensing groove 150. A positioning hole 1302 for inserting the positioning rods 1501 is formed on the lower end face of the support plate 130. A shaping plate 170 with a semi-circular cross-section and an upward-facing arc surface is fixed to the upper end face of the support plate 130.
[0035] An installation groove 120 is provided near the front and rear lines of the parking space. A glass plate 1202 is provided at the opening of the installation groove 120. The bottom of the installation groove 120 is provided with an inclined surface 1203 that slopes towards the center of the parking space. The sensor light 1201 is provided on the inclined surface 1203.
[0036] The working principle of the parking space vehicle presence sensing device in this embodiment is as follows:
[0037] When a vehicle prepares to enter or exit a parking space, it will pass over the deceleration protrusion 110 along the front or rear edge of the parking space. The vehicle runs over the rubber sheet 1101, causing it to deform and transmit pressure to the shaping plate 170, which in turn transmits it to the support plate 130. The support plate 130 moves downward against the spring force of the spring 160, causing the positioning rod 1501 to slide within the positioning hole 1302 until the support plate 130 contacts and triggers the micro switch 140. Once triggered, the micro switch 140 controls the sensor light 1201 in the mounting slot 120 to turn on, providing illumination for the video monitoring terminal. The sensor light 1201 remains on for 1 to 5 minutes, during which time the video monitoring terminal acquires a clear image of the parking space, accurately identifying parking space occupancy and vehicle information. After the vehicle leaves, the spring 160 returns the support plate 130 and the rubber sheet 1101 to their initial positions.
[0038] With the above settings, when the underground parking garage is dimly lit, the sensor light 1201 provides good illumination for the video monitoring terminal, reducing image blur and ensuring accurate parking space monitoring. The sensor light 1201 only turns on for 1-5 minutes when a vehicle passes the speed bump 110, avoiding unnecessary prolonged lighting and saving energy.
[0039] The rubber skin 1101 acts as a buffer, reducing vehicle bumps and impacts on the ground, improving driving comfort and protecting the road surface. The rubber skin 1101 and the sensor groove 150 protect the sensing system, extending its service life.
[0040] The inclined surface 1203 at the bottom of the mounting groove 120 concentrates the light from the sensor lamp 1201 onto the center of the parking space, reducing blind spots and improving lighting effect and uniformity.
[0041] In summary, the above are merely preferred embodiments of this embodiment. All equivalent changes and modifications made in accordance with the scope of the patent application of this embodiment shall fall within the scope of the patent of this embodiment.
