Description

Technical Field

[0001] This utility model relates to the technical field of parking space availability display devices, specifically a parking lot entrance / exit pedal count availability display device. Background Technology

[0002] With the acceleration of urbanization and the continuous growth of motor vehicle ownership, the problem of parking difficulties has become increasingly prominent. To improve parking lot management efficiency and user experience, intelligent parking space availability display systems are gradually becoming standard equipment in modern parking lots. These systems typically use vehicle detection devices at parking lot entrances and exits to count the number of vehicles entering and exiting in real time, calculate the remaining parking spaces based on the total number of spaces, and finally dynamically display the results on an external display screen, guiding drivers to quickly determine whether to enter the parking lot, thereby reducing entrance congestion and improving traffic efficiency. Currently, common vehicle entry and exit detection methods mainly include geomagnetic sensors, infrared beams, video recognition, and pressure-sensitive pedals. Among these, pressure-sensitive pedals are widely used in small and medium-sized parking lots due to their simple structure, reliable response, and strong anti-interference capabilities. Existing technologies include devices that detect vehicle passage by installing single or multiple pressure-sensitive pedals on the ground. When a vehicle's tires pass over the pedal, a signal is triggered, achieving a counting function.

[0003] However, most existing margin display devices adopt a fixed structure, and the installation angle of the LED display screen is not adjustable, making it difficult to adapt to different terrains or viewing angles. At the same time, the size of the display screen is usually matched with the mounting frame. When the original display screen is damaged and the same model of spare parts cannot be purchased, or when a new model of display screen with a larger size and higher brightness needs to be replaced due to technical upgrades, or when the display area needs to be adjusted to adapt to different installation environments (such as curves, slopes, and long-distance observation positions), the entire display screen needs to be replaced or complex modifications need to be made, resulting in high maintenance costs and poor flexibility. Utility Model Content

[0004] This utility model aims to address the shortcomings of the prior art by providing a remaining display device for parking lot entrance and exit pedal counting. To solve the above problems, the horizontal angle of the LED display screen is adjusted by the synergistic action of the adjustment components, using a rotating plate and through holes. At the same time, the sliding slider drives the pull plate to move, and the spacing is adjusted by a threaded limit structure to adapt to different sizes of display screens. Finally, the top limit plate, adjustment screw, and nut press the top together, improving installation stability and maintenance convenience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a parking lot entrance / exit pedal counting balance display device, comprising: a cement base, an entrance pressure plate a on the top of the cement base, an entrance pressure plate b on one side of the entrance pressure plate a, an exit pressure plate a on the top of the cement base, an exit pressure plate b on one side of the exit pressure plate a, a display frame base fixedly installed on the top of the cement base, and an adjustment assembly disposed on the top of the cement base.

[0012] This utility model provides a parking lot entrance / exit pedal counter remaining display device, which has the following features:

[0013] Beneficial effects:

[0014] The advantages of this utility model are that, by adjusting the settings of the components, the rotating plate can be fixed with the through hole of the display frame base using bolts, thereby adjusting the horizontal orientation of the LED display screen. At the same time, the slider slides in the slide groove, driving the pull plate to move.

At the same time, the microcontroller performs logical judgment on the signals, and only when the signals are triggered in a specific order within a set time window are they recognized as valid passage events. This avoids duplicate counting caused by single-wheel triggering or incorrect sequence, thus improving the accuracy and reliability of parking space statistics. Attached Figure Description

[0025] This application provides a parking lot entrance / exit pedal count balance display device. This device allows for horizontal angle adjustment of the LED display screen through the coordinated action of adjusting components. A rotating plate and through-hole are used to move the pull plate, and a threaded limiting structure adjusts the spacing to accommodate different screen sizes. A top limiting plate, adjusting screws, and nuts then secure the top, improving installation stability and ease of maintenance. The following provides a detailed description of this parking lot entrance / exit pedal count balance display device. It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of embodiments.

[0026] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] Please see Figure 1-6 This embodiment provides a parking lot entrance / exit pedal count balance display device, comprising: a cement base 1, an entrance pressure plate a101 on the top of the cement base 1, an entrance pressure plate b102 on one side of the entrance pressure plate a101, an exit pressure plate a103 on the top of the cement base 1, an exit pressure plate b104 on one side of the exit pressure plate a103, and a display frame base 3 fixedly mounted on the top of the cement base 1; and an adjustment assembly disposed on the top of the cement base 1, the adjustment assembly including: the top of the display frame base 3... A rotating plate 302 is provided, and a back plate 6 is fixedly installed on the top of the rotating plate 302. Three connecting blocks b404 are provided on one side of the back plate 6, and two connecting blocks a501 are provided on one side of the back plate 6. A pull plate a4 is fixedly connected to one end of the three connecting blocks b404, and a pull plate b5 is fixedly connected to one side of the two connecting blocks a501. Two threaded limiting rods 402 are fixedly connected to one side of the pull plate b5 and the pull plate a4. A top limiting plate 7 is provided on the top of the back plate 6, and two adjusting screws 701 are fixedly connected to the bottom of the top limiting plate 7.

[0028] The LED display screen 8 can be adjusted horizontally by using the rotating plate 302 and the through hole 303 of the display frame base 3 with bolts. At the same time, the slider 603 slides in the groove 602 of the back plate 6, which drives the pull plate a4 to move. The pull plate a4 is connected to the screw hole 605 of the back plate 6 with the threaded limit rod 402, the limit nut 403 and the threaded sleeve 405 to adjust the distance between the pull plate a4 and the pull plate b5 to accommodate LED display screens of different sizes. Finally, the top limit plate 7, the adjusting screw 701 and the adjusting nut 702 work together to press the top of the LED display screen 8, which improves the installation stability and maintenance convenience.

[0029] Secondly, by coordinating the entrance pressure plate a101, entrance pressure plate b102, exit pressure plate a103, and exit pressure plate b104, the gravity sensor 201 on the mounting plate 2 can detect the triggering sequence and time interval of vehicles passing over each pressure plate sequentially, thus achieving accurate identification of the vehicle's entry and exit direction. Simultaneously, the microcontroller 301 within the display frame base 3 performs logical judgment on the signals, recognizing only valid passage events triggered in a specific sequence within a set time window. This avoids duplicate counting due to single-wheel triggering or incorrect sequence, improving the accuracy and reliability of parking space statistics.

[0030] The display stand base 3 has through holes 303 at the top and the rotating plate 302 at the bottom. The display stand base 3 and the rotating plate 302 are connected by bolts and nuts.

[0031] During installation, place the rotating plate 302 and the back plate 6 on top of the display stand base 3, adjust the orientation of the back plate 6 to a suitable horizontal angle, and then align the through holes 303 at the top of the display stand base 3 and the bottom of the rotating plate 302 with each other, and fix them with bolts and nuts to secure the rotating plate 302.

[0032] Among them, a slider 603 is fixedly connected to one side of both connecting block a501 and connecting block b404. Two limiting grooves 401 are opened on both sides of the back plate 6. A support platform 601 is fixedly connected to one side of the back plate 6. A fixing plate 604 is fixedly connected to one side of the back plate 6. Two through holes are opened on the top of the fixing plate 604. Two adjusting nuts 702 are threadedly connected to the outer side of the adjusting screw 701. An LED display screen 8 is provided between the pull plate a4 and the pull plate b5. Multiple sliding grooves 602 are opened on one side of the back plate 6. The slider 603 is slidably connected to the sliding groove 602. One end of the threaded limiting rod 402 extends into the interior of the limiting groove 401. A limiting nut 403 is threadedly connected to the outer side of the threaded limiting rod 402. A threaded sleeve 405 is fixedly connected to one side of the limiting nut 403. Threaded holes 605 corresponding to the positions of the threaded sleeve 405 are opened on both sides of the back plate 6, and the threaded holes 605 are threadedly connected to the threaded sleeve 405.

[0033] When it is necessary to replace the LED display screen 8 with a different specification, the two adjusting nuts 702 on the adjusting screw 701 and the limiting nut 403 and threaded sleeve 405 on the threaded limiting rod 402 can be turned to release the limiting of the top limiting plate 7, the pulling plate a4, and the pulling plate b5 respectively. At the same time, the pulling plates a4 and b5 are pulled away from the back plate 6 to change the distance between the pulling plates a4 and b5 until the distance between the pulling plates a4 and b5 is greater than the length of the LED display screen 8. The LED display screen 8 is then placed on the support platform 601, and one side of the pulling plates a4 and b5 is placed against the LED display screen 8. Next, tighten the limiting nuts 403 on the threaded limiting rod 402 on both sides of the LED display screen 8, so that the threaded sleeve 405 on one side of the limiting nut 403 is screwed into the screw hole 605 on one side of the back plate 6 to complete the fixing of the LED display screen 8. Then, make the bottom of the top limiting plate 7 rest against the top of the LED display screen 8, and then tighten the two adjusting nuts 702 to move the two adjusting nuts 702 towards the fixing plate 604 at the same time until the two adjusting nuts 702 contact the fixing plate 604 to fix the adjusting screw 701 and the top limiting plate 7, thereby fixing the LED display screen 8.

[0034] The display base 3 has a microcontroller 301 fixedly installed inside. Multiple spring dampers 203 are fixedly connected to the bottom of the inlet pressure plate a101, inlet pressure plate b102, outlet pressure plate a103 and outlet pressure plate b104. Multiple protrusions 202 are fixedly connected to the bottom of the inlet pressure plate b102, outlet pressure plate a103 and outlet pressure plate b104. Mounting plates 2 are provided at the bottom of the inlet pressure plate b102, outlet pressure plate a103 and outlet pressure plate b104. Gravity sensors 201 are fixedly installed at the bottom of the multiple protrusions 202, and the protrusions 202 and gravity sensors 201 are positioned correspondingly.

[0035] When a vehicle enters or exits the parking lot, gravity sensors 201 installed on the ground in the vehicle detection entrance pressure plate a101, entrance pressure plate b102, exit pressure plate a103, and exit pressure plate b104 sense the vehicle's passage and generate corresponding entry or exit signals. These signals are transmitted via cables to the signal input interface on the microcontroller 301. After receiving the signals, the microcontroller 301 inside the display device uses a variable value register as a counter to record the current total number of vehicles in the parking lot. When the system starts, the counter is initialized to zero.

[0036] To accurately determine the vehicle's entry and exit direction and avoid duplicate counting caused by the front and rear wheels running over the gravity sensor 201, the microcontroller 301 employs a logic mechanism based on trigger sequence and time window collaborative judgment. Only when the entrance pressure plate a101 and entrance pressure plate b102, or the exit pressure plate a103 and exit pressure plate b104, are triggered sequentially in a specific order within a set time window, is the system considered a valid vehicle passage event. Specifically, if the gravity sensor 201 at the bottom of the entrance pressure plate a101 is triggered first, and the gravity sensor 201 at the bottom of the entrance pressure plate b102 is subsequently triggered within the time window, it is determined that a vehicle has entered, and the counter is incremented. Conversely, if the gravity sensor 201 at the bottom of the exit pressure plate a103 is triggered first, and the gravity sensor 201 at the bottom of the exit pressure plate b104 is subsequently triggered within the time window, it is determined that a vehicle has exited, and the counter is decremented. If only a single gravity sensor 201 is triggered, or the triggering sequence is illogical, or the interval between two triggers exceeds the time window, it is considered an invalid signal and will not be counted.

[0037] Through the above mechanism, the system can effectively identify the direction of vehicle passage, avoid counting errors caused by repeated triggering of the front and rear wheels, and thus calculate the total number of vehicles in the parking lot in real time and accurately. Combined with the preset total number of parking spaces, the system calculates the number of remaining parking spaces, and the calculation results are sent to the LED display screen 8 for dynamic display.

[0038] The working principle is as follows:

[0039] During installation, place the rotating plate 302 and the back plate 6 on top of the display stand base 3, adjust the orientation of the back plate 6 to a suitable horizontal angle, and then align the through holes 303 at the top of the display stand base 3 and the bottom of the rotating plate 302 with each other, and fix them with bolts and nuts to secure the rotating plate 302.

[0040] Furthermore, when it is necessary to replace the LED display screen 8 with one of different specifications, the two adjusting nuts 702 on the adjusting screw 701 and the limiting nut 403 and threaded sleeve 405 on the threaded limiting rod 402 can be turned to release the limiting of the top limiting plate 7, the pulling plate a4, and the pulling plate b5 respectively. At the same time, the pulling plates a4 and b5 are pulled away from the back plate 6 to change the distance between the pulling plates a4 and b5 until the distance between the pulling plates a4 and b5 is greater than the length of the LED display screen 8. The LED display screen 8 is then placed on the support platform 601, and one side of the pulling plates a4 and b5 is then placed against the support platform 601. Next, tighten the limiting nuts 403 on the threaded limiting rod 402 on both sides of the LED display screen 8, so that the threaded sleeve 405 on one side of the limiting nut 403 is screwed into the screw hole 605 on one side of the back plate 6 to complete the fixing of the LED display screen 8. Then, make the bottom of the top limiting plate 7 rest against the top of the LED display screen 8, and then tighten the two adjusting nuts 702, so that the two adjusting nuts 702 move towards the fixing plate 604 at the same time until the two adjusting nuts 702 contact the fixing plate 604 to fix the adjusting screw 701 and the top limiting plate 7, thereby fixing the LED display screen 8.

[0041] When a vehicle enters or exits the parking lot, gravity sensors 201 installed on the ground in the vehicle detection entrance pressure plate a101, entrance pressure plate b102, exit pressure plate a103, and exit pressure plate b104 sense the vehicle's passage and generate corresponding entry or exit signals. These signals are transmitted via cables to the signal input interface on the microcontroller 301. After receiving the signals, the microcontroller 301 inside the display device uses a variable value register as a counter to record the current total number of vehicles in the parking lot. When the system starts, the counter is initialized to zero.

[0042] To accurately determine the vehicle's entry and exit direction and avoid duplicate counting caused by the front and rear wheels running over the gravity sensor 201 separately, the microcontroller 301 employs a logic mechanism based on trigger sequence and time window collaborative judgment. Only when the entrance pressure plate a101 and entrance pressure plate b102, or the exit pressure plate a103 and exit pressure plate b104, are triggered sequentially in a specific order within a set time window, is the system considered a valid vehicle passage event. Specifically, if the gravity sensor 201 at the bottom of the entrance pressure plate a101 is triggered first, and the gravity sensor 201 at the bottom of the entrance pressure plate b102 is subsequently triggered within the time window, it is determined that a vehicle has entered, and the counter is incremented. Conversely, if the gravity sensor 201 at the bottom of the exit pressure plate a103 is triggered first, and the gravity sensor 201 at the bottom of the exit pressure plate b104 is subsequently triggered within the time window, it is determined that a vehicle has exited, and the counter is decremented. If only a single gravity sensor 201 is triggered, or the triggering sequence is illogical, or the interval between two triggers exceeds the time window, it is considered an invalid signal and will not be counted.

[0043] Through the above mechanism, the system can effectively identify the direction of vehicle passage, avoid counting errors caused by repeated triggering of the front and rear wheels, and thus calculate the total number of vehicles in the parking lot in real time and accurately. Combined with the preset total number of parking spaces, the system calculates the number of remaining parking spaces. The calculation results are sent to the LED display screen 8 for dynamic display. This mechanism is a conventional existing technology, so it will not be described in detail.
