Description

Technical Field

[0001] This invention belongs to the technical field of parking management systems, and in particular relates to a fast and convenient parking system based on fiber optic sensors. Background Technology

[0002] With the rapid development of the national economy, the number of private cars has increased significantly, and correspondingly, the demand for parking has surged. To address urban parking needs, regulate vehicle parking order, and reduce road occupancy, parking lots have gradually become an indispensable part of urban infrastructure.

[0003] Traditional parking lots typically divide the space into parking zones, each containing multiple parking spaces, thus achieving rational planning and utilization of the parking lot's internal space. Sensors are used to detect whether each parking space is occupied, and a display screen at the parking lot entrance shows the number of remaining parking spaces.

[0004] However, current technology can only indicate to drivers whether there are remaining parking spaces in a parking lot, but it cannot effectively explain the location or actual condition of the remaining parking spaces. Therefore, in practical applications, drivers spend a significant amount of time searching for remaining parking spaces, severely impacting the user experience. Furthermore, with continuous advancements in automotive technology, the market offers a variety of vehicle sizes, while parking space sizes remain relatively constant. Therefore, differences in vehicle size and parking position directly affect the usability of parking spaces. When a large vehicle is parked adjacent to a remaining parking space, or when adjacent vehicles are not centered, the difficulty of parking in the remaining space increases significantly, severely impacting the actual parking experience. Summary of the Invention

[0023] The second adjustment unit is used to adjust the distance between the two connecting seats when the volume label is a large vehicle volume label, so that the distance between the two edge measuring fiber optic sensors is adjusted to the second preset spacing.

[0024] Furthermore, the reminder module also includes:

[0025] A guiding unit, used to form a light-emitting guiding line in a parking space based on the distance between two edge-positioning fiber optic sensors, includes:

[0028] Furthermore, the regional-level processing module includes:

[0029] The quantity calculation unit is used to calculate the number of remaining parking spaces in the parking area based on the number of parking space-level processing modules that generate parking space occupancy signals and the total number of parking spaces in the parking area.

[0034] The judgment subunit is used to determine the parking difficulty level of a parking area based on the proportion of small cars, the proportion of large cars, and the number of remaining parking spaces in the parking area. This determination includes: when the proportion of small cars is greater than or equal to the proportion of large cars, and the number of remaining parking spaces is greater than a preset number, the parking difficulty level is determined to be low; when the proportion of small cars is less than the proportion of large cars, and the number of remaining parking spaces is greater than a preset number, the parking difficulty level is determined to be medium; and when the proportion of small cars is less than the proportion of large cars, and the number of remaining parking spaces is less than or equal to a preset number, the parking difficulty level is determined to be high.

[0040] (1) The fast and convenient parking system based on fiber optic sensors described in this invention can collect vehicle weight parameters through a parking space sensing module and detect whether a vehicle has entered between two edge-positioning fiber optic sensors to determine the occupancy status of the parking space. Simultaneously, a volume label can be generated through a parking space-level processing module, and the spacing between the two edge-positioning fiber optic sensors can be adjusted through an adjustment module to adjust and plan the parking position of the vehicle in the parking space, improving the rationality of parking space space utilization and reducing the subsequent parking difficulty for large vehicles. Furthermore, a regional subsystem can calculate the parking difficulty level of the parking area and display the number of remaining parking spaces and parking difficulty icons, allowing drivers to quickly determine the parking status of vehicles in the parking area when searching for a parking space, thereby improving the user experience during the parking process.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] A fast and convenient parking system based on fiber optic sensors, which can be... Figure 1 The following is an illustration. In this embodiment, the fast and convenient parking system based on fiber optic sensors includes a parking space-level subsystem and a region-level subsystem. The parking space-level subsystem is set in the parking space and is used to sense, process, and display the vehicles parked in the current parking space. The region-level subsystem is set in the parking area formed by multiple parking spaces and is used to process and display the vehicles parked in the current parking area.

[0050] Specifically, the parking space-level subsystem includes: a parking space perception module, a parking space-level processing module, an adjustment module, and an alert module. The parking space perception module senses the parking status of vehicles within the parking space. This module includes a weight-measuring fiber optic sensor and two edge-positioning fiber optic sensors. The weight-measuring fiber optic sensor is located at the entrance of the parking space, while the two edge-positioning fiber optic sensors are located on either side of the center of the parking space. In operation, the weight-measuring fiber optic sensor collects vehicle weight parameters before the vehicle enters the parking space, allowing the subsequent processing module to determine the vehicle's size based on these parameters. The edge-positioning fiber optic sensors detect whether a vehicle parked inside the parking space has entered between the two edge-positioning fiber optic sensors, thus determining the vehicle's parking position within the parking space.

[0051] It should be noted that the fiber optic weighing sensor and the fiber optic edge positioning sensor described in this embodiment are common fiber optic pressure sensors in the prior art. Their specific working principles and composition structures are well known to the public and are not part of the core inventive points of this application, so they will not be described in detail here.

[0052] To enable signal transmission between the parking space-level processing module and the parking space sensing module, the parking space-level processing module is connected to the weighing fiber optic sensor and the edge positioning fiber optic sensor via optical fibers. The parking space-level processing module is used to determine the vehicle's size type and parking location, and specifically includes a tag generation unit and a location determination unit.

[0053] The tag generation unit generates volume tags based on vehicle weight parameters collected by the fiber optic weighing sensor. Since the weight and volume of common vehicles are usually directly proportional (i.e., the heavier the vehicle, the larger its volume), before applying the fiber optic sensor-based fast and convenient parking system provided in this embodiment, a first weight threshold (e.g., 1.3 tons) and a second weight threshold (e.g., 1.8 tons) should be pre-set based on the weight of common vehicles, and the first weight threshold should be less than the second weight threshold. When the vehicle weight parameter is less than the first weight threshold, it indicates that the current vehicle's weight is relatively low, and it can be classified as a small vehicle (e.g., an A0-class sedan). Therefore, a small vehicle volume tag should be generated to facilitate subsequent adjustment of the spacing between the two edge-positioning fiber optic sensors, thereby guiding the small vehicle to be centered within the parking space and preventing it from affecting the parking difficulty of adjacent vehicles due to improper parking. When the vehicle weight parameter is greater than the second weight threshold, it indicates that the current vehicle weight is relatively low and can be identified as a large vehicle (such as an SUV). Therefore, a large vehicle volume label should be generated to facilitate subsequent adjustment of the spacing between the two edge positioning fiber optic sensors, thereby guiding the large vehicle to be parked in the center inside the parking space and preventing it from encroaching on the available space inside the adjacent parking space.

[0054] The position determination unit determines the vehicle's parking position based on the detection results from the edge positioning fiber optic sensors. When the edge positioning fiber optic sensors detect that the vehicle is not parked between two sensors, it indicates that the vehicle is not parked according to the system's plan, thus generating an alarm signal to remind the driver to adjust the vehicle's parking position during subsequent processing. When the edge positioning fiber optic sensors detect that the vehicle is parked between two sensors, it indicates that the vehicle is parked according to the system's plan, thus generating a parking space occupancy signal to indicate that the parking space is in use during subsequent processing.

[0055] Accordingly, to facilitate the driver's perception of the signals generated by the location judgment unit, the parking space-level subsystem also includes a reminder module. The reminder module is communicatively connected to the parking space-level processing module, allowing signals generated by the location judgment unit to be sent to the reminder module. In this embodiment, the reminder module includes a parking space-level display unit and an alarm unit. The parking space-level display unit displays a parking space occupancy icon (exemplarily, the display unit can be positioned above the current parking space, and the parking space occupancy icon can be a red pattern on the icon) upon receiving a parking space occupancy signal, allowing the driver to determine that the current parking space is occupied. The alarm unit issues an alarm notification (an alarm sound or flashing light) upon receiving an alarm signal, allowing the driver to adjust the vehicle's parking position promptly after receiving the alarm notification.

[0056] In practical applications, the same parking space may be used by vehicles of different sizes. Therefore, the parking space-level subsystem should also include an adjustment module that communicates with the parking space-level processing module. During use, the adjustment module adjusts the distance between the two edge-positioning fiber optic sensors according to the volume label, ensuring that the distance between the two edge-positioning fiber optic sensors matches the volume label. This allows for flexible adjustment of the vehicle's parking position within the parking space based on its size, thereby making efficient use of the space.

[0057] Optionally, the adjustment module may include: an execution unit, a first adjustment unit, and a second adjustment unit. The execution unit, comprising a guide rail and two connecting seats, is used to drive the movement of two edge-positioning fiber optic sensors. When setting up this system, a trench should first be dug in the ground of the parking space area, and the guide rail should be placed inside the trench so that its length direction is perpendicular to the vehicle entry direction of the parking space. Then, the two connecting seats are slidably mounted on the guide rail and connected to the two edge-positioning fiber optic sensors respectively. When it is necessary to adjust the distance between the two edge-positioning fiber optic sensors, the two connecting seats can be driven to slide on the guide rail, thereby increasing or decreasing the distance between the two edge-positioning fiber optic sensors. The first adjustment unit is used to adjust the distance between the two connecting seats when the volume label is for a small vehicle, so that the distance between the two edge-positioning fiber optic sensors is adjusted to a first preset distance. The second adjustment unit is used to adjust the distance between the two connecting seats when the volume label is for a large vehicle, so that the distance between the two edge-positioning fiber optic sensors is adjusted to a second preset distance. Since the width of a common vehicle is directly proportional to its volume (i.e., the larger the vehicle volume, the wider its width), before applying the fast and convenient parking system based on fiber optic sensors provided in this embodiment, a first preset distance (e.g., 1750mm) and a second preset distance (e.g., 2000mm) should be preset according to the width of a common vehicle. The first preset distance should be smaller than the second preset distance so that the system can reasonably plan the parking position of the vehicle in the parking space based on the width of the vehicle.

[0058] It should be noted that the guide rail and connecting seat described in this embodiment can refer to the linear motor mechanism in the prior art, where the guide rail is the track of the linear motor with a stator, and the connecting seat is the sliding block of the linear motor with a mover. After receiving the corresponding control signal, the connecting seat can slide on the guide rail. Operators can also choose other mature devices in the prior art as the specific implementation method for the guide rail and connecting seat, as long as they can successfully achieve the purpose of "adjusting the distance between the two edge positioning fiber optic sensors".

[0059] Optionally, to help the driver clearly understand the distance between the two edge positioning sensors when driving the vehicle into the parking space and reduce the number of times the vehicle's parking position needs to be adjusted, the reminder module in this embodiment may also include a guide unit for forming an luminous guide line in the parking space based on the distance between the two edge positioning fiber optic sensors.

[0060] Specifically, the guidance unit may include a first guidance subunit and a second guidance subunit. The first guidance subunit includes two first guide light strips for forming a light-emitting guide line, the two first guide light strips being arranged parallel to each other, and the distance between the two first guide light strips being equal to a first preset spacing. The second guidance subunit includes two second guide light strips for forming a light-emitting guide line, the two second guide light strips being parallel to each other, and the distance between the two second guide light strips being equal to a second preset spacing. When the adjustment module adjusts the distance between the two edge-measuring fiber optic sensors to the first preset spacing, the two first guide light strips in the first guidance subunit will illuminate, forming a light-emitting guide line in the parking space based on the two first guide light strips, guiding the driver to enter. When the adjustment module adjusts the distance between the two edge-measuring fiber optic sensors to the second preset spacing, the two second guide light strips in the second guidance subunit will illuminate, forming a light-emitting guide line in the parking space based on the two second guide light strips, guiding the driver to enter.

[0061] Since common parking lots are usually divided into multiple parking areas, and each parking area contains multiple parking spaces, drivers need to first select a parking area in the parking lot, and then find a parking space within the selected parking area. To help drivers quickly determine the number of remaining parking spaces and the difficulty of parking in the current parking area, the area-level subsystem in this embodiment includes an area-level processing module and an area-level display module.

[0062] The area-level processing module communicates with each parking space-level processing module within the parking area, while the area-level display module communicates with the area-level processing module to transmit signals. In operation, the area-level processing module calculates the number of remaining parking spaces and the parking difficulty level within the parking area, generating a parking difficulty icon based on the difficulty level. The area-level display module then displays the number of remaining parking spaces and the parking difficulty icon, allowing drivers to quickly understand the current status of the parking area.

[0063] Optionally, the area-level processing module in this embodiment may include a quantity calculation unit and a difficulty calculation unit. The quantity calculation unit is used to calculate the number of remaining parking spaces in the parking area based on the number of parking space-level processing modules generating parking space occupancy signals and the total number of parking spaces in the parking area (remaining parking spaces in the parking area = total number of parking spaces in the parking area - number of parking space-level processing modules generating parking space occupancy signals). The difficulty calculation unit is used to calculate the parking difficulty level of the parking area based on the number of parking space-level processing modules generating small vehicle volume labels, the number of parking space-level processing modules generating large vehicle volume labels, the number of parking space-level processing modules generating parking space occupancy signals, and the number of remaining parking spaces in the parking area, and generate a parking difficulty icon based on the parking difficulty level.

[0064] To calculate the parking difficulty level and generate the parking difficulty icon, the difficulty calculation unit may include: a first calculation subunit, a second calculation subunit, a judgment subunit, and a generation subunit.

[0065] The first calculation subunit calculates the proportion of small vehicles based on the number of parking space-level processing modules generating small vehicle volume tags and the number of parking space-level processing modules generating parking space occupancy signals. The small vehicle proportion is the ratio of the number of parking space-level processing modules generating small vehicle volume tags to the number generating parking space occupancy signals. The small vehicle proportion reflects the number of small vehicles parked in the currently occupied parking spaces within the parking area. Generally, a higher small vehicle proportion indicates that the remaining parking spaces in the current parking area are more convenient for subsequent parking.

[0066] The second calculation subunit calculates the proportion of large vehicles based on the number of parking space-level processing modules generating large vehicle volume tags and the number of parking space-level processing modules generating parking space occupancy signals. The large vehicle proportion is the ratio of the number of parking space-level processing modules generating large vehicle volume tags to the number generating parking space occupancy signals. The large vehicle proportion reflects the number of large vehicles parked in the currently occupied parking spaces within the parking area. Generally, a higher proportion of large vehicles indicates that the remaining parking spaces in the current parking area are less convenient for subsequent parking.

[0067] The judgment subunit determines the parking difficulty level of a parking area based on the proportion of small cars, the proportion of large cars, and the number of remaining parking spaces. It should be noted that before applying the fiber optic sensor-based fast and convenient parking system provided in this embodiment, a preset remaining number (e.g., 40% of the total number of parking spaces in the current parking area) should be pre-set based on the total number of parking spaces in the current parking area. When the number of remaining parking spaces is less than the preset remaining number, it indicates that most of the parking spaces in the current parking area are already in use. In this case, the available space for vehicles in the current parking area will be affected by the parked vehicles, thus increasing the parking difficulty. Correspondingly, due to the size difference between small and large cars, if a small car parks according to the guidance of the parking space-level subsystem, its parking space will form a large open area. Subsequent vehicles can then use this open area to move, thus reducing parking difficulty to some extent. If a large car parks according to the guidance of the parking space-level subsystem, the open area formed by its parking space is smaller, making it difficult for subsequent vehicles to use this open area to move, thus increasing parking difficulty to some extent. Based on the above reasons, in this embodiment, determining the parking difficulty level of a parking area according to the proportion of small cars, the proportion of large cars, and the number of remaining parking spaces in the parking area may include: when the proportion of small cars is greater than or equal to the proportion of large cars, and the number of remaining parking spaces is greater than a preset number, the parking difficulty level of the parking area is determined to be low difficulty; when the proportion of small cars is less than the proportion of large cars, and the number of remaining parking spaces is greater than a preset number, the parking difficulty level of the parking area is determined to be medium difficulty; when the proportion of small cars is less than the proportion of large cars, and the number of remaining parking spaces is less than or equal to a preset number, the parking difficulty level of the parking area is determined to be high difficulty.

[0068] After determining the parking difficulty level of a parking area, the parking difficulty level will be sent to the generation sub-unit. The generation sub-unit will then generate a parking difficulty icon based on the parking difficulty level. Specifically, generating a parking difficulty icon based on the parking difficulty level can include: generating a low-difficulty icon when the parking area's parking difficulty level is low; generating a medium-difficulty icon when the parking area's parking difficulty level is medium; and generating a high-difficulty icon when the parking area's parking difficulty level is high.

[0069] For example, in this embodiment, the parking difficulty icons for low difficulty, medium difficulty, and high difficulty can all be of the same shape and distinguished by different icon colors (e.g., low difficulty parking icon is green, medium difficulty parking icon is yellow, and high difficulty parking icon is red) so that drivers can quickly make a judgment based on the parking difficulty icons.

[0070] Based on the above embodiments, the fast and convenient parking system based on fiber optic sensors may further include a central subsystem located in a parking lot formed by multiple parking areas. Optionally, the central subsystem includes a central processing module and a central display module, wherein the central processing module is communicatively connected to all area-level processing modules in the parking lot, and the central display module is located at the entrance of the parking lot and is communicatively connected to the central processing module.

[0071] During operation, the central processing module calculates the total number of remaining parking spaces in the parking lot based on the number of remaining spaces in each parking area (the total number of remaining parking spaces in the parking lot is equal to the sum of the remaining parking spaces in all parking areas). The central display module displays the number of remaining parking spaces and parking difficulty icons for each parking area, allowing drivers to quickly understand the status of each parking area when entering the parking lot, thereby improving parking convenience.

[0072] The effects of the above solution are explained below:

[0073] This embodiment provides a fast and convenient parking system based on fiber optic sensors. It generates volume tags based on vehicle weight parameters and adjusts the spacing between two edge-positioning fiber optic sensors based on these tags. This guides and restricts the vehicle's parking position within the parking space, improving space utilization and reducing the difficulty of parking subsequent vehicles. Secondly, this embodiment guides vehicle parking through a guidance unit, improving the ease with which a vehicle can enter the area between the two edge-positioning fiber optic sensors. Furthermore, this embodiment calculates the parking difficulty level of the parking area and displays it using a parking difficulty icon, thereby improving the driver's convenience in selecting a parking area.

[0074] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
