Description

Technical Field

[0001] The present invention relates to the technical field of Internet of Things, and in particular to a smart parking lot management method and system. Background Art

[0002] With the improvement of people's living standards, my country's car ownership has been growing rapidly year by year. The current shortage of cars and parking spaces in China exceeds 50 million. The difficulty of finding parking in cities has become a problem for most car owners. Traditional parking lot management methods require manual payment collection and searching for parking spaces, which is inefficient and prone to errors. Furthermore, manual management makes it difficult to achieve real-time monitoring and statistical analysis of vehicle information within the parking lot. In traditional parking lots, drivers often spend a considerable amount of time searching for parking spaces and waiting in line to pay, which significantly reduces the parking experience. Traditional parking lot security monitoring relies primarily on manual patrols and video surveillance, which have blind spots and delayed response times, making it difficult to detect and respond to abnormal situations in a timely manner. Traditional parking lots require significant manpower and material resources for management and maintenance, resulting in high operating costs. While smart parking lots require a larger initial investment, they can reduce overall operating costs in the long term by improving management efficiency and reducing labor costs. Compared to traditional parking lot management methods, smart parking lot management systems utilize technologies such as automatic license plate recognition and automated navigation to achieve unmanned parking management, significantly improving parking efficiency and shortening parking time. The smart parking management system provides real-time parking information and navigation services, helping drivers quickly find available parking spaces and eliminating the hassle of searching for them within the parking lot. Furthermore, the system supports multiple payment methods, including contactless payment, making payments quick and convenient, enhancing the user's parking experience. Using technologies such as video surveillance and vehicle identification, the smart parking management system enables security monitoring within the parking lot. In the event of an anomaly, the system promptly issues an alarm and provides relevant records and evidence, helping to strengthen parking lot safety management. The smart parking management system monitors and analyzes real-time data such as vehicle flow, dwell time, and parking fee collection within the parking lot, helping managers to stay informed of parking lot operations, optimize management decisions, and improve management efficiency.

By improving parking efficiency and optimizing resource allocation, the smart parking system helps alleviate urban parking difficulties and improve urban traffic conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Figure 1 This is a smart parking lot management method described in the present invention. DETAILED DESCRIPTION

[0048] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0049] One embodiment of the present invention provides a smart parking lot management method, characterized in that the method includes:

[0050] S1: Collects parking space information in real time, including the number of available spaces and their locations, and provides query services to car owners through the application layer;

[0051] S2: Automatically identify and record vehicle information, including license plate number, vehicle brand, and vehicle color, and record the vehicle's entry time;

[0052] S3: Records the vehicle’s location, uploads it to the central management system, and provides the vehicle owner with directions to the vehicle;

[0053] S4: Identify the information of the vehicle leaving the site, calculate the time the vehicle has been parked in the site based on the information of the vehicle entering the site, and calculate the fee based on the time. The fee is collected through non-stop electronic toll collection technology. After receiving the fee, the barrier is lifted to let the vehicle leave.

[0054] The working principle and effect of the above technical solution are as follows: The system uses various sensors installed in the parking lot to collect real-time parking space information, including the number of available spaces and their locations. This information is updated in real time and transmitted to a central management system. Simultaneously, the system provides real-time query services to vehicle owners through user terminals such as the application layer, allowing them to check parking availability anytime and anywhere and choose the most suitable parking lot and space. By collecting and providing real-time parking space information to vehicle owners, they can quickly find available spaces, reducing the time spent searching within the parking lot and improving parking efficiency. When a vehicle enters the parking lot, the system automatically identifies the license plate number using high-definition cameras and license plate recognition technology, comparing it with the system's database to confirm the vehicle's identity. In addition to identifying the license plate, the system also records information such as the vehicle's make, color, and time of entry, providing a basis for subsequent fee calculation and vehicle management. The system's video surveillance system records vehicle locations in real time, ensuring safe and orderly parking. Vehicle owners can use the mobile application layer to query their vehicle's location and obtain route navigation services to their vehicle. When a vehicle leaves the parking lot, the system automatically identifies the vehicle's departure information using license plate recognition technology and compares it with the vehicle's entry information. Based on the time difference between the vehicle's entry and exit, the system automatically calculates the parking fee and collects it through electronic toll collection. Once the fee is received, the barrier automatically raises, allowing the vehicle to exit smoothly. This automated and intelligent management approach reduces manual intervention and labor costs while improving management efficiency and accuracy. Managers can monitor parking conditions in real time through the system and quickly respond to various incidents and issues. Car owners can use mobile apps and other channels to query parking space information, navigate to their vehicle's location, and automatically pay parking fees. These convenient services significantly enhance the user experience. Users no longer need to worry about finding a parking space or forgetting to pay. The system enhances parking lot security through technologies such as video surveillance and license plate recognition. Vehicle entry and exit records are clear and traceable, providing strong evidence for resolving disputes and unusual situations. The system also monitors unusual parking conditions, such as improperly parked vehicles or trespassing, and promptly notifies management for action.

[0055] One embodiment of the present invention collects parking space information in real time, including the number of available spaces and the location of the spaces, and provides query services to car owners through the application layer, including:

[0056] S11: Detect parking space occupancy in real time through sensing technology and upload the collected data to the central management system;

[0057] S12: The central management system cleans, integrates, and stores the received data, and processes the data to generate information on the number of available parking spaces and the locations of the parking spaces;

[0058] S13: The data interface of the central management system is connected to the application layer, and the information on the number of vacant parking spaces and the location of parking spaces is synchronized to the application layer in real time, and then the application layer provides query services to car owners.

[0059] The working principle and effect of the above technical solution are as follows: Various sensors installed in the parking lot monitor parking space occupancy in real time. These sensors can accurately identify whether a vehicle is parked in a parking space, thereby obtaining the real-time status of the parking space. The detected parking space occupancy data is uploaded to a central management system in real time. This process is typically carried out over the network to ensure data timeliness and accuracy. After receiving the data from the various sensors, the central management system cleans and consolidates it. This step primarily removes erroneous and duplicate data to ensure data quality for subsequent processing. The cleaned and consolidated data is further processed to generate information on the number of available parking spaces and their locations. The system dynamically updates parking space status based on real-time data to ensure accuracy. The processed data is stored in the central management system's database for subsequent query and analysis. The central management system's data interface connects to the application layer used by car owners to ensure real-time data synchronization. This connection is based on an API (Application Programming Interface), ensuring data security and stability. The number of available parking spaces and their locations are synchronized to the application layer in real time. This allows car owners to query the real-time parking situation at any time through the application layer. Drivers enter relevant query criteria on the application layer. The system retrieves the corresponding parking space information from the database based on these criteria and displays it to the driver. Drivers can then choose a suitable parking space based on this information. The system uses sensing technology to monitor parking space occupancy in real time and instantly uploads this data to the central management system, ensuring that drivers receive the most up-to-date parking information. Drivers can easily query the number and location of available parking spaces in the parking lot through the mobile application layer, eliminating the need to search for a space in person, significantly saving time and effort. By updating parking space information in real time, the system guides drivers to available spaces, avoiding wasted parking resources and improving overall parking lot utilization. The system automatically monitors parking space occupancy without manual intervention, reducing management costs.

[0060] One embodiment of the present invention automatically identifies vehicle information, including license plate number, vehicle brand, and vehicle color, and records the vehicle's entry time, including:

[0061] S21: Uses video detection technology to detect whether a vehicle has entered the recognition area. When a vehicle enters the recognition area, the camera automatically captures the vehicle image and ensures that the license plate number, vehicle brand, and vehicle color are clearly visible;

[0062] S22: pre-processing the collected image, and using a license plate positioning algorithm to accurately locate the license plate position in the pre-processed image, and obtaining the vehicle license plate number based on image processing technology;

[0063] S23: When the license plate recognition system recognizes the license plate and completes the relevant information processing, the system will automatically record the vehicle's entry time and store the license plate number, vehicle brand, vehicle color and entry time information in the central management system.

[0064] The working principle and effect of the above technical solution are as follows: Video detection technology, specifically cameras, is used to monitor and detect whether a vehicle enters a pre-defined recognition area. When a vehicle enters the recognition area, the camera is automatically triggered to capture an image of the vehicle. This process ensures that key information such as the license plate number, vehicle brand, and vehicle color are clearly visible in the image. To achieve this, the camera typically uses a high-resolution, high-definition image sensor and is equipped with an intelligent fill-light system to cope with recognition requirements under varying lighting conditions. The captured vehicle image undergoes preprocessing to improve image quality and enhance the accuracy of subsequent processing. Preprocessing steps may include noise removal, contrast enhancement, and grayscale conversion. A license plate location algorithm is then used to accurately locate the license plate in the preprocessed image. Various license plate location methods exist, including image-based color information methods, texture analysis methods, and edge detection methods. After determining the license plate location, the license plate recognition system uses a character recognition algorithm to recognize the characters on the license plate to obtain the license plate number. In addition to the license plate number, the license plate recognition system may also use image processing technology to identify the vehicle brand and color. This is usually based on other features of the vehicle image, such as the vehicle's shape and color distribution. While the license plate recognition system completes relevant information processing, it automatically records the vehicle's entry time and stores information such as the license plate number, vehicle brand, vehicle color, and entry time in the central management system. The system can automatically detect vehicle entry, capture images, identify license plates, and record information, without the need for human intervention throughout the entire process, greatly improving processing efficiency. Using advanced image processing technology and algorithms, the system can complete license plate recognition and other information extraction in a very short time, reducing vehicle waiting time. The system can not only identify license plate numbers, but also vehicle brands and colors, providing more detailed vehicle information to facilitate subsequent management and inquiries.

[0065] One embodiment of the present invention records the location of a vehicle, uploads it to a central management system, and provides the vehicle owner with a route to the vehicle, including:

[0066] S31: The positioning device obtains the precise location of the vehicle through positioning technology and uploads the collected vehicle location data to the central management system through the data transmission device;

[0067] S32: The central management system receives the positioning data, stores the positioning data in a storage device, cleans, integrates and analyzes the positioning data, and updates the vehicle's location information to ensure the timeliness and accuracy of the data;

[0068] S33: After receiving a route request to the vehicle's location from the vehicle owner at the application layer, the central management system uses the map service to plan the route and displays the planned route to the vehicle owner.

[0069] The working principle and effect of the above technical solution are as follows: The positioning device transmits the collected vehicle location data securely and stably to the central management system via a built-in communication module. The central management system's server receives the data packets from the positioning device and performs preliminary data verification and analysis to ensure data integrity and accuracy. The central management system stores the received vehicle location data in a high-performance storage device, such as a database or cloud storage service, for subsequent data analysis and querying. The system cleans the stored data to remove duplicate, erroneous, or invalid data to ensure data purity. The system integrates the cleaned data to form a comprehensive vehicle location information database and conducts regular or real-time data analysis to monitor vehicle operating status and predict traffic flow. Vehicle owners, through applications on devices such as smartphones and tablets, request a route to the central management system. The central management system then uses a professional mapping service and its API to perform route planning. The mapping service calculates the optimal route based on the vehicle owner's current location and the vehicle's current location. The system then displays the planned route to the vehicle owner in a graphical format, including information such as the starting point, destination, waypoints, and estimated travel time. Based on the displayed route information, drivers can choose the most appropriate driving plan to reach their vehicle. The system can obtain and update vehicle location information in real time, ensuring that drivers and management personnel are aware of the vehicle's latest location at all times. Drivers can quickly check their vehicle's location through an app or website, eliminating the need to search blindly in the parking lot. The system automatically plans the optimal route to their vehicle, saving time and improving travel efficiency. The system continuously monitors vehicle location and immediately notifies drivers or management personnel if any anomalies are detected (such as vehicle theft or unusual movement). The central management system features data backup to ensure the security and reliability of vehicle location data and prevent data loss.

[0070] One embodiment of the present invention identifies vehicle departure information, calculates the vehicle's parking time based on vehicle entry information, calculates a fee based on the time, collects the fee using non-stop electronic toll collection technology, and upon receipt of the fee, raises the barrier and allows the vehicle to depart, including:

[0071] S41: When the vehicle approaches the parking lot exit, the license plate recognition system captures and recognizes the license plate number again, compares it with the license plate number recorded in the entry record, confirms that it is the same vehicle leaving the lot, and records the departure time;

[0072] S42: Automatically calculate the length of time the vehicle has been in the parking lot based on the time the vehicle enters and leaves the parking lot, and automatically calculate the payable fee based on the parking lot's charging standards;

[0073] S43: The parking lot management system sends a payment request to the car owner through non-stop electronic toll collection technology and electronic payment technology. After receiving and confirming the successful payment information, it automatically raises the barrier at the parking lot exit.

[0074] The working principle and effect of the above technical solution are as follows: When a vehicle approaches the parking lot exit, the license plate recognition system installed at the exit captures the vehicle's front image again and uses image processing technology to identify the license plate number. The system compares the recognized license plate number with the license plate number recorded upon entry to confirm that it is the same vehicle leaving the lot. This step is critical to ensuring accurate charging. Once the vehicle's departure is confirmed, the system immediately records the current departure time. Based on the vehicle's entry time and the current recorded departure time, the system automatically calculates the vehicle's parking fee based on the parking lot's established fee rate (4 yuan / hour) and the calculated parking time. The parking lot management system then sends a payment request to the vehicle owner using non-stop electronic toll collection or electronic payment technology. After receiving the payment request, the vehicle owner follows the prompts to complete the payment. After receiving the payment information, the system immediately confirms the payment to ensure successful payment. Once the payment is successful and confirmed, the parking lot management system automatically sends a command to the exit barrier to raise it, allowing the vehicle to leave. Using license plate recognition and electronic toll collection, the system quickly identifies vehicles and processes payments, reducing wait times at the exit and improving traffic efficiency. Faster passage reduces congestion at parking lot exits, helping to improve surrounding traffic conditions. Drivers can simply pay electronically without having to stop, find change, or wait for a toll collector, significantly improving payment convenience. This reduces wait times at the exit and increases parking satisfaction. The system automatically calculates parking duration based on vehicle entry and exit times, eliminating manual timekeeping errors. From vehicle identification to fee calculation, payment confirmation, and barrier raising, the entire process is highly automated, reducing the potential for manual intervention and human error.

[0075] One embodiment of the present invention provides a smart parking lot management system, characterized in that the system includes:

[0076] Vacancy display system: collects parking space information in real time, including the number of available spaces and their locations, and provides query services to car owners through the application layer;

[0077] Automatic recording system: automatically identifies and records vehicle information, including license plate number, vehicle brand and vehicle color, and records the vehicle's entry time;

[0078] Route guidance system: records the vehicle's location, uploads it to the central management system, and provides the vehicle owner with a route to the vehicle;

[0079] Toll collection system: Identifies the information of vehicles leaving the site, calculates the time the vehicle has been parked in the site based on the information of vehicles entering the site, and calculates the fee based on the time. The fee is collected through non-stop electronic toll collection technology. After receiving the fee, the barrier is raised to allow the vehicle to leave.

[0080] The working principle and effect of the above technical solution are as follows: The system uses various sensors installed in the parking lot to collect real-time parking space information, including the number of available spaces and their locations. This information is updated in real time and transmitted to a central management system. Simultaneously, the system provides real-time query services to vehicle owners through user terminals such as the application layer, allowing them to check parking availability anytime and anywhere and choose the most suitable parking lot and space. By collecting and providing real-time parking space information to vehicle owners, they can quickly find available spaces, reducing the time spent searching within the parking lot and improving parking efficiency. When a vehicle enters the parking lot, the system automatically identifies the license plate number using high-definition cameras and license plate recognition technology, comparing it with the system's database to confirm the vehicle's identity. In addition to identifying the license plate, the system also records information such as the vehicle's make, color, and time of entry, providing a basis for subsequent fee calculation and vehicle management. The system's video surveillance system records vehicle locations in real time, ensuring safe and orderly parking. Vehicle owners can use the mobile application layer to query their vehicle's location and obtain route navigation services to their vehicle. When a vehicle leaves the parking lot, the system automatically identifies the vehicle's departure information using license plate recognition technology and compares it with the vehicle's entry information. Based on the time difference between the vehicle's entry and exit, the system automatically calculates the parking fee and collects it through electronic toll collection. Once the fee is received, the barrier automatically raises, allowing the vehicle to exit smoothly. This automated and intelligent management approach reduces manual intervention and labor costs while improving management efficiency and accuracy. Managers can monitor parking conditions in real time through the system and quickly respond to various incidents and issues. Car owners can use mobile apps and other channels to query parking space information, navigate to their vehicle's location, and automatically pay parking fees. These convenient services significantly enhance the user experience. Users no longer need to worry about finding a parking space or forgetting to pay. The system enhances parking lot security through technologies such as video surveillance and license plate recognition. Vehicle entry and exit records are clear and traceable, providing strong evidence for resolving disputes and unusual situations. The system also monitors unusual parking conditions, such as improperly parked vehicles or trespassing, and promptly notifies management for action.

[0081] In one embodiment of the present invention, the vacancy display system includes:

[0082] Parking space detection device: uses sensing technology to detect parking space occupancy in real time and uploads the collected data to the central management system;

[0083] Data processing device: The central management system cleans, integrates and stores the received data, and processes the data to generate information on the number of vacant parking spaces and the location of parking spaces;

[0084] Information synchronization device: The data interface of the central management system is connected to the application layer, and the information on the number of vacant parking spaces and the location of parking spaces is synchronized to the application layer in real time, and then the application layer provides query services to car owners.

[0085] The central management system synchronizes the number of available parking spaces and parking space location information, and also synchronizes the estimated waiting time to the application layer. The application layer then provides the remaining waiting time query service to the car owner. The estimated waiting time is calculated using the following formula:

[0086]

[0087] Among them, H represents the number of vehicles waiting ahead, W represents the number of vehicles waiting in the buffer zone, which indicates the number of vehicles waiting to enter the exit in the parking lot or on the surrounding roads, C represents the number of available parking spaces in the parking lot, λ represents the vehicle departure rate, that is, the number of vehicles leaving the parking lot per unit time, μ represents the vehicle entry rate, that is, the number of vehicles entering the parking lot per unit time. Both λ and μ are values ​​calculated by the system based on historical data from the recent period, T represents the average service time, that is, the time required for each vehicle to completely leave the parking lot from the time it arrives at the exit, R represents the number of service windows, and α represents the congestion coefficient. When congestion occurs in the parking lot or on the surrounding roads, the movement speed of vehicles will slow down, resulting in increased waiting time. α adjusts the estimated waiting time based on the real-time congestion situation. The value range of α is [0,1]. When α = 0, it means there is no congestion in the parking lot, and when α = 1, it means that the parking lot is very congested.

[0088] When the required waiting time t≤30 minutes, the font color of the required waiting time in the application layer turns green, and the car owner is informed that the waiting time is moderate;

[0089] When 30<t≤60, the font color of the required waiting time in the application layer turns yellow, and the driver is prompted to wait a little longer and choose another parking lot according to the waiting time;

[0090] When t>60, the required waiting time of the application layer turns red, and warns the car owner that the waiting time is too long and he needs to consider changing the parking location.

[0091] The working principle and effect of the above technical solution are as follows: Various sensors installed in the parking lot monitor parking space occupancy in real time. These sensors can accurately identify whether a vehicle is parked in a parking space, thereby obtaining the real-time status of the parking space. The detected parking space occupancy data is uploaded to a central management system in real time. This process is typically carried out over the network to ensure data timeliness and accuracy. After receiving the data from the various sensors, the central management system cleans and consolidates it. This step primarily removes erroneous and duplicate data to ensure data quality for subsequent processing. The cleaned and consolidated data is further processed to generate information on the number of available parking spaces and their locations. The system dynamically updates parking space status based on real-time data to ensure accuracy. The processed data is stored in the central management system's database for subsequent query and analysis. The central management system's data interface connects to the application layer used by car owners to ensure real-time data synchronization. This connection is based on an API (Application Programming Interface), ensuring data security and stability. The number of available parking spaces and their locations are synchronized to the application layer in real time. This allows car owners to query the real-time parking situation at any time through the application layer. Drivers enter relevant query criteria on the application layer. The system retrieves relevant parking space information from the database based on these criteria and displays it to the driver. Drivers can use this information to select a suitable parking space. Drivers can also view the estimated wait time in real time, allowing them to make more informed parking choices, reduce wait times, and enhance their parking experience. The system uses sensing technology to monitor parking space occupancy in real time and instantly uploads this data to a central management system, ensuring that drivers receive the most up-to-date parking information. Drivers can easily query the number and location of available parking spaces in the parking lot through the mobile application layer, eliminating the need to search for a space in person, significantly saving time and effort. By updating parking space information in real time, the system guides drivers to available spaces, avoiding wasted parking resources and improving overall parking lot utilization. The system automatically monitors parking space occupancy without manual intervention, reducing management costs.

[0092] In one embodiment of the present invention, the automatic recording system includes:

[0093] Video detection device: Use video detection technology to detect whether a vehicle enters the recognition area. When a vehicle enters the recognition area, the video camera automatically captures the vehicle image and ensures that the license plate number, vehicle brand and vehicle color are clearly visible;

[0094] Image processing device: pre-processes the collected image, uses the license plate positioning algorithm to accurately locate the license plate position in the pre-processed image, and obtains the vehicle license plate number based on image processing technology;

[0095] Information storage device: When the license plate recognition system recognizes the license plate and completes the relevant information processing, the system will automatically record the vehicle's entry time and store the license plate number, vehicle brand, vehicle color and entry time information in the central management system.

[0096] The working principle and effect of the above technical solution are as follows: Video detection technology, specifically cameras, is used to monitor and detect whether a vehicle enters a pre-defined recognition area. When a vehicle enters the recognition area, the camera is automatically triggered to capture an image of the vehicle. This process ensures that key information such as the license plate number, vehicle brand, and vehicle color are clearly visible in the image. To achieve this, the camera typically uses a high-resolution, high-definition image sensor and is equipped with an intelligent fill-light system to cope with recognition requirements under varying lighting conditions. The captured vehicle image undergoes preprocessing to improve image quality and enhance the accuracy of subsequent processing. Preprocessing steps may include noise removal, contrast enhancement, and grayscale conversion. A license plate location algorithm is then used to accurately locate the license plate in the preprocessed image. Various license plate location methods exist, including image-based color information methods, texture analysis methods, and edge detection methods. After determining the license plate location, the license plate recognition system uses a character recognition algorithm to recognize the characters on the license plate to obtain the license plate number. In addition to the license plate number, the license plate recognition system may also use image processing technology to identify the vehicle brand and color. This is usually based on other features of the vehicle image, such as the vehicle's shape and color distribution. While the license plate recognition system completes relevant information processing, it automatically records the vehicle's entry time and stores information such as the license plate number, vehicle brand, vehicle color, and entry time in the central management system. The system can automatically detect vehicle entry, capture images, identify license plates, and record information, without the need for human intervention throughout the entire process, greatly improving processing efficiency. Using advanced image processing technology and algorithms, the system can complete license plate recognition and other information extraction in a very short time, reducing vehicle waiting time. The system can not only identify license plate numbers, but also vehicle brands and colors, providing more detailed vehicle information to facilitate subsequent management and inquiries.

[0097] In one embodiment of the present invention, the guidance system includes:

[0098] Positioning device: The positioning device obtains the precise location of the vehicle through positioning technology and uploads the collected vehicle location data to the central management system through the data transmission device;

[0099] Information pre-processing device: The central management system receives positioning data, stores the positioning data in a storage device, cleans, integrates and analyzes the positioning data, and updates the vehicle's location information to ensure the timeliness and accuracy of the data;

[0100] Route planning device: After receiving a route request to the vehicle's location from the car owner at the application layer, the central management system uses the map service to plan the route and displays the planned route to the car owner.

[0101] The working principle and effect of the above technical solution are as follows: The positioning device transmits the collected vehicle location data securely and stably to the central management system via a built-in communication module. The central management system's server receives the data packets from the positioning device and performs preliminary data verification and analysis to ensure data integrity and accuracy. The central management system stores the received vehicle location data in a high-performance storage device, such as a database or cloud storage service, for subsequent data analysis and querying. The system cleans the stored data to remove duplicate, erroneous, or invalid data to ensure data purity. The system integrates the cleaned data to form a comprehensive vehicle location information database and conducts regular or real-time data analysis to monitor vehicle operating status and predict traffic flow. Vehicle owners, through applications on devices such as smartphones and tablets, request a route to the central management system. The central management system then uses a professional mapping service and its API to perform route planning. The mapping service calculates the optimal route based on the vehicle owner's current location and the vehicle's current location. The system then displays the planned route to the vehicle owner in a graphical format, including information such as the starting point, destination, waypoints, and estimated travel time. Based on the displayed route information, drivers can choose the most appropriate driving plan to reach their vehicle. The system can obtain and update vehicle location information in real time, ensuring that drivers and management personnel are aware of the vehicle's latest location at all times. Drivers can quickly check their vehicle's location through an app or website, eliminating the need to search blindly in the parking lot. The system automatically plans the optimal route to their vehicle, saving time and improving travel efficiency. The system continuously monitors vehicle location and immediately notifies drivers or management personnel if any anomalies are detected (such as vehicle theft or unusual movement). The central management system features data backup to ensure the security and reliability of vehicle location data and prevent data loss.

[0102] In one embodiment of the present invention, the charging system includes:

[0103] Vehicle departure recording system: When a vehicle approaches the parking lot exit, the license plate recognition system captures and identifies the license plate number again, compares it with the license plate number recorded in the entry record, confirms that it is the same vehicle leaving the lot, and records the departure time;

[0104] Fee calculation device: automatically calculates the length of time a vehicle has been in the parking lot based on the time the vehicle enters and leaves the lot, and automatically calculates the payable fee based on the parking lot's charging standards;

[0105] Automatic barrier lifting device: The parking lot management system sends a payment request to the car owner through non-stop electronic toll collection technology and electronic payment technology. After receiving and confirming the successful payment information, it automatically lifts the barrier at the parking lot exit.

[0106] The calculation formula of the parking fee can be obtained by the following formula:

[0107]

[0108] Among them, P represents the parking fee and E represents the parking time.

[0109] The working principle and effect of the above technical solution are as follows: When a vehicle approaches the parking lot exit, the license plate recognition system installed at the exit captures the vehicle's front image again and uses image processing technology to identify the license plate number. The system compares the recognized license plate number with the license plate number recorded upon entry to confirm that it is the same vehicle leaving the lot. This step is critical to ensuring accurate charging. Once the vehicle's departure is confirmed, the system immediately records the current departure time. Based on the vehicle's entry time and the current recorded departure time, the system automatically calculates the vehicle's parking fee based on the parking lot's established fee rate (4 yuan / hour) and the calculated parking time. The parking lot management system then sends a payment request to the vehicle owner using non-stop electronic toll collection or electronic payment technology. After receiving the payment request, the vehicle owner follows the prompts to complete the payment. After receiving the payment information, the system immediately confirms the payment to ensure successful payment. Once the payment is successful and confirmed, the parking lot management system automatically sends a command to the exit barrier to raise it, allowing the vehicle to leave. Using license plate recognition and electronic toll collection, the system quickly identifies vehicles and processes payments, reducing wait times at the exit and improving traffic efficiency. Faster passage reduces congestion at parking lot exits, helping to improve surrounding traffic conditions. Drivers can simply pay electronically without having to stop, find change, or wait for a toll collector, significantly improving payment convenience. This reduces wait times at the exit and increases parking satisfaction. The system automatically calculates parking duration based on vehicle entry and exit times, eliminating manual timekeeping errors. From vehicle identification to fee calculation, payment confirmation, and barrier raising, the entire process is highly automated, reducing the potential for manual intervention and human error.
