Description

Technical Field

[0001] The present invention belongs to the field of intelligent transportation and the Internet of Things, and in particular relates to a car-finding system combined with a payment terminal. Background Art

[0002] The main problems in finding a car in a traditional parking lot are as follows:

[0003] (1) The layout is complex and the owner's memory is easily blurred. For example, the layout of large multi-storey or underground parking lots has no unified pattern, the signs are difficult to understand, and it is difficult for the owner to remember the parking location after leaving for a long time.

[0004] (2) The signs are unclear and lack effective guidance. Some parking lot signs are damaged, blocked, have small fonts, or unclear colors. In addition, there are only static signs that cannot provide accurate route guidance.

[0005] (3) The methods of finding a car are very limited. Using car keys to find a car is not very effective in large parking lots. Sound is easily drowned out by ambient noise, and lights are difficult to detect. Relying on landmarks to find a car is easy to get confused and may lose reference.

[0006] (4) Most existing parking lots rely solely on license plate recognition (OCR) systems to confirm vehicle information, but license plate recognition may fail due to problems such as stains and obstructions.

[0007] (5) Existing parking management systems usually rely on a single record of vehicle entry and exit and are unable to track the dynamic location of vehicles in real time.

[0008] (6) In the prior art, parking space management in parking lots mostly relies on manual or simple sensors. The real-time and accuracy of parking space status are low, which easily causes parking space information lag or error.

[0009] (7) In existing parking systems, the payment process is usually separated from parking space search and exit navigation, and users need to spend extra time looking for their vehicles and exits.

[0010] (8) The parking management system database in the prior art usually has problems such as untimely updates and inconsistent data. Especially during peak hours, information delays will affect the efficiency of parking space management. Summary of the invention

[0011] In view of the above deficiencies in the prior art, the purpose of the present invention is to provide a car finding system combined with a payment terminal, which can solve the problem of finding a car in a large parking lot, provide a full-link service, and improve the car finding experience.

[0018] The user payment and parking location query module is used to support users to query the parking location of their vehicles through the payment terminal and complete the payment of parking fees when the user is ready to leave.

[0019] Furthermore, it also includes: an intelligent navigation planning module, which is used to provide the user with the best navigation route from the current parking space to the parking lot exit according to the built-in parking lot map after the user completes the payment; a data storage device, which is used to receive and store data from the data acquisition device and the data detection and analysis device, and has a built-in background database, and all relevant data of the parking lot are stored in the background database; a visual display and management device, which is used to manage the parking lot related data stored in the background database, and display various vehicle related information generated by the data detection and analysis device to the user in a mobile terminal visual manner.

[0020] Furthermore, the vehicle appearance features collected by the license plate recognition and vehicle feature collection module include: vehicle color, model and brand.

[0021] Furthermore, the camera tracking and positioning module in the parking lot confirms the current position of the vehicle based on the vehicle images collected in real time by each camera in the parking lot and the vehicle identification data, and after monitoring the vehicle entering a new camera coverage area, captures the latest position of the vehicle based on the image taken by the new camera, and updates the latest position data until the vehicle is parked in the corresponding parking space, thereby forming the vehicle's movement trajectory.

[0022] Furthermore, the parking space number marking and database updating module monitors the usage status of each parking space in the parking lot in real time according to the image information captured by the camera, and after determining that a vehicle has been parked in the parking space, it automatically binds the parking space number with the vehicle identification information of the vehicle.

[0023] Furthermore, the user payment and parking location query module supports the following two methods for parking location query and payment, including: scanning a payment QR code or entering a license plate number.

[0024] Furthermore, the intelligent navigation planning module sends the generated optimal navigation route to the smart display screen or mobile application in the parking lot.

[0025] Furthermore, the intelligent navigation planning module further controls the intelligent lighting system in the parking lot to light up the lights on the optimal navigation route.

[0026] Furthermore, the visualization display and management module obtains the parking space number and parking duration of the user's vehicle based on the information fed back by the user payment and parking location query module, automatically calculates the parking fee and generates a payment QR code or other payment method.

[0027] Furthermore, the backend database adopts a distributed architecture.

[0028] Furthermore, the information stored in the backend database includes license plate number, vehicle feature information, vehicle entry and exit records, parking space status, vehicle location information, parking lot map, navigation algorithm and parking fee calculation information.

[0029] The beneficial effects of the present invention are as follows: The car-finding system combined with the payment terminal of the present invention solves the problem of finding a car in a large parking lot by combining the user's car-finding scene and the payment scene, provides a full-link service, and improves the car-finding experience. The present invention can improve parking efficiency and management accuracy, reduce the user's car-finding time, optimize the parking space utilization rate, improve the user's convenience of leaving the parking lot, enhance the intelligent level of the parking lot, reduce management costs, and improve user experience. By building an efficient, intelligent, and safe parking management system, it helps the development of smart cities and smart transportation.

[0030] (1) Dual recognition based on OCR and vehicle features

[0031] The present invention collects the license plate number and the appearance features of the vehicle (such as color, model, brand, etc.) through the camera at the entrance, and combines the OCR (optical character recognition) technology to automatically identify the identity information of the vehicle and generate a unique vehicle identification. That is, the dual recognition mechanism combining OCR technology and vehicle appearance features can accurately identify the vehicle even when the license plate is unclear or blocked. Vehicle appearance feature extraction is used to assist license plate recognition, especially when the license plate is damaged or unclear, to ensure accurate collection of vehicle information. The reliability and accuracy of license plate recognition are enhanced by collecting and comparing vehicle appearance features, especially when the license plate is difficult to recognize, the risk of recognition failure can be effectively reduced.

[0032] The present invention can greatly improve the accuracy and efficiency of vehicle recognition by adopting this method, and avoid manual intervention. When the license plate cannot be recognized, the vehicle appearance characteristics can be used for secondary confirmation, which improves the robustness and fault tolerance of the system.

[0033] (2) Fully automated vehicle tracking and parking space binding

[0034] The present invention introduces a camera tracking system inside the parking lot, which can track the position and movement trajectory of the vehicle in real time from the moment the vehicle enters the parking lot. After the vehicle is parked, the system automatically determines that the parking is completed by detecting the static state of the vehicle, and binds the vehicle to the specific parking space number, and synchronizes the information to the background database in real time. Through the full dynamic tracking and automatic binding of parking spaces, the system can realize the real-time positioning of the vehicle, ensuring that the user can query the precise location of the vehicle at any time, greatly improving the parking experience.

[0035] (3) Automated parking space status monitoring and management

[0036] The present invention monitors the parking space status in real time through cameras or sensors, and automatically synchronizes with the background database to update the parking space occupancy status, ensuring that the parking space status information is always accurate. Automated parking space monitoring technology not only improves the accuracy of parking space management, but also effectively optimizes parking space utilization, avoids the waste of vacant parking spaces, and thus improves the overall operational efficiency of the parking lot.

[0037] The status (free / occupied) of each parking space in the parking lot is monitored in real time through cameras or sensors, and the system dynamically adjusts parking space allocation based on parking space occupancy.

[0038] The present invention adopts this method to realize accurate dynamic management of vehicles in the parking lot, reducing the time users spend looking for vehicles in the parking lot. The system uses camera tracking technology to realize fully automated parking space management, improve the operational efficiency of the parking lot and the accuracy of vehicle scheduling.

The present invention realizes the seamless integration of payment and navigation systems, opens up the last mile of parking lot management, not only reduces the time for users to find vehicles and exits, but also provides intelligent guidance for traffic flow in the parking lot, reducing congestion.

[0041] The present invention adopts this method to realize a convenient and flexible payment process. Users can query parking spaces and fees by license plate number or QR code, which improves user experience. The system can intelligently plan navigation routes, help users quickly find vehicles and leave efficiently, and reduce congestion and queuing time.

[0042] (5) Efficient backend database and real-time data synchronization

[0043] The system of the present invention is equipped with a background database management module to record the vehicle's entry and exit time, parking space occupancy, parking fees and other information in real time. The database automatically synchronizes with the front-end system (license plate recognition, payment terminal, camera network) in real time to ensure data consistency and timeliness. The present invention uses a real-time data synchronization mechanism to ensure that data such as vehicle entry and exit, parking space status, payment information, etc. in the parking lot can be synchronized between the background system and the front-end device in real time to ensure data consistency. Through distributed databases and real-time data synchronization technology, the system can dynamically update vehicle and parking space information, avoid confusion in parking space management due to data lag, and ensure efficient operation of the parking lot.

[0044] The present invention adopts this method to realize the whole process of parking lot management digitization and intelligence, and the operation data of the parking lot (such as vehicle flow, parking time, parking space utilization rate, etc.) can be obtained in real time. The present invention provides efficient operation support for parking lot management, reduces management costs, and improves parking lot operation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

In the present invention, Internet of Things technology can be used to connect cameras, payment terminals, navigation systems, etc. to build an intelligent management network in the parking lot.

[0074] 11. Smart parking system

[0075] Smart parking system refers to a system that combines information technology and intelligent devices to realize automated parking management. Through sensors, cameras, payment terminals and other devices, the system can dynamically monitor the use of parking spaces, provide vehicle navigation, parking fee collection and other services, and improve parking management efficiency and user experience.

[0076] The present invention proposes a car-finding system combined with a payment terminal, which involves the fields of intelligent transportation, Internet of Things, image recognition, data visualization, AI technology, etc. The system is more in line with user scenarios and can visualize and manage intelligent identification, positioning and navigation of parking lots.

[0077] like Figure 1 and Figure 2 As shown, the car finding system combined with the payment terminal of the present invention includes: a data collection device 100, a data storage device 200, a data detection and analysis device 300 and a visualization display and management device 400.

[0078] Specifically, the data collection device 100 includes multiple groups of parking lot cameras and sensors, which are installed at multiple locations in the parking lot, respectively, to collect vehicle information in the location area. The camera uses a high-resolution camera. The vehicle information may include: vehicle appearance features, parking space images, parking lot images, etc.

[0079] For example, N groups of parking lot cameras and sensors are provided, namely, camera 1 and sensor 1, camera 2 and sensor 2, ..., camera N and sensor N, which can be respectively set at the entrance, exit, and various passages of the parking lot.

[0080] The data detection and analysis device 300 is used to process and analyze vehicle information in real time. Figure 1 The data detection and analysis device 300 includes: a license plate recognition and vehicle feature collection module 310, a camera tracking and positioning module in the parking lot 320, a parking space number marking and database update module 330, a user payment and parking location query module 340 and an intelligent navigation planning module 350.

[0081] Specifically, the license plate recognition and vehicle feature acquisition module 310 is used to identify the license plate number using the OCR technology through the vehicle image captured by the camera installed at the entrance of the parking lot, and to capture the vehicle appearance features, and to combine the license plate number and the vehicle appearance features to form vehicle identification data, and to record the vehicle identification data in the background database. The vehicle appearance features include: vehicle color, model and brand, etc.

[0082] When a vehicle enters the parking lot, the camera at the entrance will use OCR (optical character recognition) technology to identify the license plate number and record the unique identification of the vehicle. OCR technology combined with a deep learning algorithm for vehicle appearance feature extraction can accurately extract vehicle information. Even if the license plate cannot be clearly identified, a secondary match can be performed through appearance features.

[0083] At the same time, the camera collects the vehicle's appearance characteristics (such as color, model, brand, etc.) and combines it with the license plate number to create complete vehicle identification data. The vehicle identification data is transmitted to the backend database in real time and associated with the vehicle's activities in the parking lot.

[0084] The camera tracking and positioning module 320 in the parking lot is used to continuously monitor the position of the vehicle based on the vehicle images and vehicle identification data collected in real time by various cameras in the parking lot, and update the latest position of the vehicle in real time to ensure that the vehicle's position information is accurate at any time.

[0085] Specifically, high-resolution cameras are installed at various passages and important nodes in the parking lot, and computer vision technology is used to analyze vehicle images captured by the cameras. The camera tracking and positioning module 320 in the parking lot confirms the current position of the vehicle based on the vehicle images and vehicle identification data collected in real time by various cameras in the parking lot, and after monitoring the vehicle entering a new camera coverage area, it captures the latest position of the vehicle based on the image captured by the new camera, and updates the latest position data until the vehicle is parked in the corresponding parking space, thereby continuously tracking the movement path of the vehicle and forming a motion trajectory.

[0086] The parking space number marking and database updating module 330 is used to identify all parking space numbers in the vehicle based on the image information collected by the camera, and when a vehicle is detected to be parked in a parking space, it automatically binds the vehicle to the parking space number of the parking space and records the information in the background database.

[0087] The parking space number marking and database updating module 330 monitors the use status (free or occupied) of each parking space in the parking lot in real time based on the image information captured by the camera, and automatically determines whether the vehicle has parked in the parking space by detecting the static state of the vehicle. After determining that the vehicle has parked in the parking space, the parking space number is automatically bound to the vehicle identification information of the vehicle (i.e., the vehicle license plate number and vehicle appearance characteristics), and the information is recorded in the background database.

[0088] The user payment and parking location query module 340 is used to support the user to query the parking location of the vehicle through the payment terminal and complete the payment of the parking fee when the user is ready to leave.

[0089] In an embodiment of the present invention, the user payment and parking location query module 340 supports the following two methods for parking location query and payment, including: scanning a payment QR code or entering a license plate number.

[0090] (1) License plate number input: Enter the license plate number on the payment terminal to query the parking space information corresponding to the license plate number and display the parking fee.

[0091] (2) Payment QR code scanning: Users can obtain parking space information and parking fees by scanning the self-service parking payment QR code on the payment terminal or mobile application.

[0092] Connect to the backend database in real time, obtain the parking space number and parking duration of the user's vehicle, automatically calculate the parking fee and generate a payment QR code or other payment method.

[0093] The intelligent navigation planning module 350 is used to provide the user with the best navigation route from the current parking space to the parking lot exit according to the built-in parking lot map after the user completes the payment, so as to help the user quickly find the vehicle and plan the exit path. The intelligent navigation planning module 350 has a built-in 3D map or a flat map of the parking lot and integrates a navigation algorithm, which can plan the best route according to the parking location of the vehicle and the exit selected by the user.

[0094] The intelligent navigation planning module 350 sends the generated optimal navigation route to the smart display screen or mobile application in the parking lot.

[0095] In addition, the intelligent navigation planning module 350 further controls the intelligent lighting system in the parking lot, lighting up the lights on the best navigation route to guide the user to quickly find the vehicle.

[0096] The data storage device 200 is used to receive and store data from the data acquisition device 100 and the data detection and analysis device 300, and has a built-in backend database to store all relevant data of the parking lot.

[0097] The backend database stores all the data in the parking lot, including license plate numbers, vehicle feature information, vehicle entry and exit records, parking space status, vehicle location information, parking lot maps, navigation algorithms, and parking fee calculation information.

[0098] In the embodiment of the present invention, the backend database adopts a distributed architecture to ensure real-time synchronous update of data and avoid information delay.

[0099] The visualization and management device 400 is used to manage the parking lot related data stored in the background database, and to display various vehicle related information generated by the data detection and analysis device 300 to the user in a mobile terminal visualization manner.

[0100] When a vehicle enters the parking lot, the system automatically generates a record of the vehicle, including license plate number, vehicle characteristics, entry time, current location and other information, and updates its location and parking space status in real time based on the movement of the vehicle.

[0101] When leaving the parking lot, the database updates the vehicle's departure time and parking fee settlement information, and releases the parking space after the vehicle leaves the parking lot.

[0102] like Figure 3 As shown, the visual display and management device 350 obtains the parking space number and parking duration of the user's vehicle based on the information fed back by the user payment and parking location query module 340, automatically calculates the parking fee and generates a payment QR code or other payment method, and sends it to the mobile terminal, and presents it to the user through an interface. The interface content includes: current location, vehicle location, vehicle information, parking time and payment amount, etc.

[0103] The following is an explanation of the workflow of the car-finding system combined with the payment terminal of the present invention.

[0104] First, the necessary hardware equipment, such as cameras and sensors, is deployed in the parking lot, and then the data is transmitted to the data center through a network connection. The data center deploys data detection and analysis devices, and uses AI algorithms to process data in real time. The analysis results are stored in the data storage device and displayed to the user through the visualization and management device. The management background provides an interface that allows administrators to configure the system and adjust the rules to adapt to the changing regulatory needs.

[0105] 1. Vehicle entry identification

[0106] When a vehicle enters the parking lot, the camera at the entrance automatically recognizes the license plate number and appearance features and generates a unique parking sign.

[0107] 2. Vehicle tracking and parking

[0108] The internal camera tracks and records the dynamic position of the vehicle in real time based on the vehicle's movement trajectory.

[0109] When a vehicle parks in a parking space, the system automatically records the parking space number and the background database updates the binding relationship between the vehicle and the parking space.

[0110] 3. User pays parking fee

[0111] When leaving the parking lot, users pay the parking fee by scanning the payment code or entering the license plate number.
