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, the number of cars in my country has increased rapidly year by year. Judging from the current number of cars and parking spaces in China, the parking space gap exceeds 50 million. The difficulty of urban parking has become a problem for most car owners. The traditional parking lot management method requires manual charging and manual search for parking spaces, which is inefficient and prone to errors. At the same time, manual management makes it difficult to achieve real-time monitoring and statistical analysis of vehicle information in the parking lot. In traditional parking lots, drivers often need to spend a lot of time looking for parking spaces and queuing to pay, which greatly reduces the user's parking experience. The security monitoring of traditional parking lots mainly relies on manual patrols and video monitoring, which has problems such as blind spots and delayed response, making it difficult to detect and respond to abnormal situations in a timely manner. Traditional parking lots require a lot of manpower and material resources for management and maintenance, resulting in high operating costs. Although the initial investment in smart parking lots is large, in the long run, the overall operating cost can be reduced by improving management efficiency and reducing labor costs. Compared with the traditional parking lot management method, the smart parking lot management system adopts technologies such as automatic license plate recognition and automatic navigation to achieve unattended parking lot management, which greatly improves parking efficiency and shortens parking time. The smart parking management system provides real-time parking space information and navigation services to help drivers quickly find free parking spaces and avoid the trouble of looking for parking spaces in the parking lot. At the same time, the system supports a variety of payment methods such as contactless payment, which facilitates users to pay quickly and improves the user's parking experience. Through video surveillance, vehicle identification and other technologies, the smart parking management system can achieve security monitoring in the parking lot. Once an abnormal situation occurs, the system can promptly alarm and provide relevant records and evidence, which will help strengthen the safety management of the parking lot. The smart parking management system can monitor and statistically analyze data such as vehicle flow, dwelling time, and charging in the parking lot in real time, helping managers to grasp the operation of the parking lot in a timely manner, optimize management decisions, and improve management efficiency.

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 in conjunction with 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 comprises:

[0050] S1: collects parking space information in real time, including the number of vacant parking spaces and parking space 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: Record the location of the vehicle, upload it to the central management system, and provide the owner with a route 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, collect the fee through non-stop electronic toll collection technology, and after receiving the fee, lift the barrier to let the vehicle leave.

[0054] The working principle and effect of the above technical solution are as follows: the system collects parking space information in real time through various sensors installed in the parking lot, including the number of vacant parking spaces, parking space locations, etc. This information is updated in real time and transmitted to the central management system. At the same time, the system provides real-time query services to car owners through user terminals such as the application layer, and car owners can check the vacant parking spaces in the parking lot anytime and anywhere, so as to choose the most suitable parking lot and parking space. By collecting parking space information in real time and providing it to car owners, car owners can quickly find vacant parking spaces, reducing the time of searching for parking spaces in the parking lot, thereby 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, and compares it with the database in the system to confirm the identity of the vehicle. While identifying the license plate, the system also records information such as the brand, color, and entry time of the vehicle, providing a basis for subsequent fee calculation and vehicle management. The system video monitoring system records the location of the vehicle in real time to ensure the safety and orderly parking of the vehicle. Car owners can query the location of their vehicles through the mobile phone application layer and obtain route navigation services to the vehicle. When a vehicle leaves the parking lot, the system automatically identifies the vehicle's departure information through license plate recognition technology and compares it with the entry information. Based on the time difference between the vehicle's entry and exit, the system automatically calculates the parking fee and collects the fee through non-stop electronic toll collection technology. Once the fee is received, the barrier will automatically lift to allow the vehicle to leave smoothly. Automated and intelligent management methods reduce manual intervention and reduce labor costs, while improving management efficiency and accuracy. Managers can monitor the parking lot situation in real time through the system and respond quickly to various events and problems. Car owners can query parking space information, navigate to the vehicle location, and automatically pay parking fees in real time through channels such as the mobile application layer. These convenient services greatly enhance the user experience. Users no longer need to worry about not being able to find a parking space or forgetting to pay fees. The system improves the safety of the parking lot through technical means such as video surveillance and license plate recognition. The vehicle entry and exit records are clear and traceable, providing strong evidence for handling disputes and abnormal situations. At the same time, the system can also monitor abnormal situations in the parking lot, such as abnormal parking of vehicles and intrusion of people, and promptly notify managers to handle them.

[0055] In one embodiment of the present invention, parking space information is collected in real time, including the number of available parking spaces and the location of parking spaces, and query services are provided 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 vacant 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 locations of parking spaces is synchronized to the application layer in real time, and then the application layer provides query services to the car owners.

[0059] The working principle and effect of the above technical solution are: the occupancy of parking spaces is detected in real time through various sensors installed in the parking lot. These sensors can accurately identify whether there are vehicles parked in the parking spaces, thereby obtaining the real-time status of the parking spaces. The detected parking space occupancy data will be uploaded to the central management system in real time. This process is usually carried out through the network to ensure the timeliness and accuracy of the data. After receiving the data from each sensor, the central management system will perform cleaning and integration. This step is mainly to remove erroneous data, duplicate data, etc., to ensure the quality of data for subsequent processing. The cleaned and integrated data will be further processed to generate information on the number of vacant parking spaces and the location of parking spaces. The system will dynamically update the parking space status according to real-time data to ensure the accuracy of the information. The processed data will be stored in the database of the central management system for subsequent query and analysis. The data interface of the central management system will be connected to the application layer used by the car owner to ensure real-time synchronization of data. This connection is based on API (application programming interface) to ensure the security and stability of the data. The information on the number of vacant parking spaces and the location of parking spaces is synchronized to the application layer in real time. In this way, the car owner can query the real-time parking space situation of the parking lot at any time through the application layer. The car owner enters the relevant query conditions on the application layer, and the system will retrieve the corresponding parking space information from the database based on these conditions and display it to the car owner. The car owner can choose a suitable parking space for parking based on this information. The system detects the occupancy of parking spaces in real time through sensing technology, and uploads the data to the central management system in real time to ensure that the parking space information obtained by the car owner is the latest. Car owners can easily query the number and location information of vacant parking spaces in the parking lot through the mobile phone application layer, without having to go to the scene to find parking spaces in person, which greatly saves time and energy. By updating parking space information in real time, the system can guide car owners to park in vacant parking spaces, avoid wasting parking space resources, and improve the overall utilization rate of parking lots. The system can automatically monitor the occupancy of parking spaces without manual intervention, reducing management costs.

[0060] An 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: Use video detection technology to detect whether a vehicle enters 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: preprocessing the collected image, and using a license plate positioning algorithm to accurately locate the license plate position in the preprocessed image, and obtaining the vehicle license plate number according to 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 is used, especially through cameras to monitor and detect whether the vehicle enters the preset recognition area. When the vehicle enters the recognition area, the camera is automatically triggered to capture the 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 usually uses a high-resolution, high-definition image sensor and is equipped with an intelligent fill light system to cope with the recognition needs under different lighting conditions. The captured vehicle image is preprocessed to improve the image quality and improve the accuracy of subsequent processing. The preprocessing steps may include denoising, contrast enhancement, grayscale, etc. The license plate positioning algorithm is used to accurately find the position of the license plate in the preprocessed image. There are many methods for license plate positioning, including image-based color information method, texture analysis-based method, edge detection-based method, etc. After the license plate position is determined, 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 identify the brand and color of the vehicle through image processing technology. This is usually based on other features of the vehicle image, such as the vehicle's shape, color distribution, etc. When the license plate recognition system 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. The system can automatically detect vehicle entry, capture images, identify license plates, and record information. The entire process does not require human intervention, which greatly improves 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, which is helpful for subsequent management and inquiries.

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

[0066] S31: The positioning device obtains the precise position of the vehicle through positioning technology, and uploads the collected vehicle position 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 location initiated by 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 to the central management system through the built-in communication module in a safe and stable manner. The server of the central management system receives the data packet from the positioning device and performs preliminary data verification and analysis to ensure the integrity and accuracy of the data. 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 query. The system cleans the stored data to remove duplicate, erroneous or invalid data to ensure the purity of the data. The system integrates the cleaned data to form a complete vehicle location information library, and performs regular or real-time data analysis to monitor the vehicle's operating status, predict traffic flow, etc. The owner initiates a route request to the central management system to the location of the vehicle through an application on a terminal device such as a smartphone or tablet computer. The central management system calls a professional map service and uses the API interface of the map service to plan the route. The map service plans the optimal driving route based on the current location of the owner and the location of the vehicle. The system displays the planned route to the owner in a graphical manner, including information such as the starting point, end point, waypoints, and estimated driving time. The car owner can choose the most appropriate driving plan to get to the location of the vehicle based on the displayed route information. The system can obtain and update the vehicle's location information in real time, ensuring that the car owner and management personnel are aware of the latest location of the vehicle at any time. The car owner can quickly check the vehicle's location through the application or web page without having to search blindly in the parking lot. The system automatically plans the best route to the vehicle for the car owner, saving time and improving travel efficiency. The system can continuously monitor the vehicle's location and immediately notify the car owner or management personnel once an abnormal situation is found (such as vehicle theft, abnormal movement, etc.). The central management system has a data backup function to ensure the security and reliability of vehicle location data and prevent data loss.

[0070] An embodiment of the present invention identifies the information of vehicle leaving the parking lot, calculates the time the vehicle has been parked in the parking lot according to the information of vehicle entering the parking lot, calculates the fee according to the time, collects the fee through the non-stop electronic toll collection technology, and after receiving the fee, the barrier is raised and the vehicle leaves, 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 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 fee payable based on the charging standards set by the parking lot;

[0073] S43: The parking lot management system sends a payment request to the car owner through the non-stop electronic toll collection technology and the electronic payment technology. After receiving and confirming the successful payment information, it automatically lifts 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 exit of the parking lot, the license plate recognition system installed at the exit will capture the front image of the vehicle again and apply image processing technology to identify the license plate number. The system will compare the recognized license plate number with the license plate number recorded when entering the lot to confirm that it is the same vehicle leaving the lot. This step is the key to ensuring the accuracy of the charges. Once the vehicle is confirmed to have left the lot, the system will immediately record the current departure time. The system will automatically calculate the length of time the vehicle has stayed in the parking lot based on the entry time recorded when the vehicle entered the lot and the exit time recorded now. Then, the system will automatically calculate the fees that the owner should pay based on the charging standards set by the parking lot (4 yuan / hour) and the calculated parking time. The parking lot management system will use non-stop electronic toll collection technology or electronic payment technology to send a payment request to the owner. After receiving the payment request, the owner will complete the payment operation according to the prompts. After receiving the payment information, the system will immediately confirm the payment to ensure that the payment is successful. Once the payment is successful and confirmed, the parking lot management system will automatically send a command to the barrier at the exit to lift it up and allow the vehicle to leave. Through license plate recognition technology and non-stop electronic toll collection technology, the system can quickly identify vehicles and process payments, reducing the waiting time of vehicles at the exit and improving traffic efficiency. Fast passage means that congestion is less likely to occur at the exit of the parking lot, which helps improve the surrounding traffic conditions. Car owners do not need to stop, get change or wait for manual payment, and can complete the payment through electronic payment, which greatly improves the convenience of payment. It reduces the waiting time of car owners at the exit and improves the satisfaction of the parking experience. The system automatically calculates the parking time according to the time when the vehicle enters and leaves the parking lot, avoiding the error of manual timing. From vehicle identification to fee calculation to payment confirmation and barrier lifting, the entire process is highly automated, reducing the possibility of manual intervention and human error.

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

[0079] Toll collection system: Identify the information of vehicle departure, calculate the time the vehicle has been parked in the venue based on the information of vehicle entry, and calculate the fee based on the time. The fee is collected through non-stop electronic toll collection technology. After the fee is received, the barrier is lifted to allow the vehicle to leave.

[0080] The working principle and effect of the above technical solution are as follows: the system collects parking space information in real time through various sensors installed in the parking lot, including the number of vacant parking spaces, parking space locations, etc. This information is updated in real time and transmitted to the central management system. At the same time, the system provides real-time query services to car owners through user terminals such as the application layer, and car owners can check the vacant parking spaces in the parking lot anytime and anywhere, so as to choose the most suitable parking lot and parking space.

[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 the parking space location information, and also synchronizes the estimated waiting time to the application layer, and then the application layer provides the remaining waiting time query service to the car owner, and the estimated waiting time is obtained by the following calculation formula:

[0086]

[0087] Among them, H represents the vehicles waiting ahead, W represents the vehicles waiting in the buffer zone, which indicates the number of vehicles waiting to enter the exit in the parking lot or the surrounding roads, C represents the number of free 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, λ and μ are both values ​​calculated by the system through historical data in 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, α represents the congestion coefficient, when congestion occurs in the parking lot or the surrounding roads, the moving speed of the vehicle will slow down, resulting in an increase in the waiting time, α adjusts the estimated value of the waiting time according to the real-time congestion situation, and the value range of α is [0,1], where α=0, it means that 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 changes to yellow, and the car owner is prompted to wait for a little longer, and the car owner needs to 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: the occupancy of parking spaces is detected in real time through various sensors installed in the parking lot. These sensors can accurately identify whether there are vehicles parked in the parking spaces, thereby obtaining the real-time status of the parking spaces. The detected parking space occupancy data will be uploaded to the central management system in real time. This process is usually carried out through the network to ensure the timeliness and accuracy of the data. After receiving the data from each sensor, the central management system will perform cleaning and integration. This step is mainly to remove erroneous data, duplicate data, etc., to ensure the quality of data for subsequent processing. The cleaned and integrated data will be further processed to generate information on the number of vacant parking spaces and the location of parking spaces. The system will dynamically update the parking space status according to real-time data to ensure the accuracy of the information. The processed data will be stored in the database of the central management system for subsequent query and analysis. The data interface of the central management system will be connected to the application layer used by the car owner to ensure real-time synchronization of data. This connection is based on API (application programming interface) to ensure the security and stability of the data. The information on the number of vacant parking spaces and the location of parking spaces is synchronized to the application layer in real time. In this way, the car owner can query the real-time parking space situation of the parking lot at any time through the application layer. The car owner enters the relevant query conditions on the application layer, and the system retrieves the corresponding parking space information from the database based on these conditions and displays it to the car owner. The car owner can choose a suitable parking space for parking based on this information. The car owner can also understand the expected waiting time of the parking lot in real time, so as to make a more reasonable parking choice, reduce waiting time and improve the parking experience. The system detects the occupancy of parking spaces in real time through sensing technology, and uploads the data to the central management system in real time to ensure that the parking space information obtained by the car owner is the latest. The car owner can easily query the number and location information of the vacant parking spaces in the parking lot through the mobile phone application layer, without having to go to the scene to find a parking space in person, which greatly saves time and energy. By updating the parking space information in real time, the system can guide the car owner to park in the vacant parking space, avoid the waste of parking space resources, and improve the overall utilization rate of the parking lot. The system can automatically monitor the occupancy of parking spaces without manual intervention, reducing management costs.

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

[0093] Video detection device: Use video detection technology to detect whether a vehicle has entered the identification area. When a vehicle enters the identification 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, and 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 is used, especially through cameras to monitor and detect whether the vehicle enters the preset recognition area. When the vehicle enters the recognition area, the camera is automatically triggered to capture the 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 usually uses a high-resolution, high-definition image sensor and is equipped with an intelligent fill light system to cope with the recognition needs under different lighting conditions. The captured vehicle image is preprocessed to improve the image quality and improve the accuracy of subsequent processing. The preprocessing steps may include denoising, contrast enhancement, grayscale, etc. The license plate positioning algorithm is used to accurately find the position of the license plate in the preprocessed image. There are many methods for license plate positioning, including image-based color information method, texture analysis-based method, edge detection-based method, etc. After the license plate position is determined, 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 identify the brand and color of the vehicle through image processing technology. This is usually based on other features of the vehicle image, such as the vehicle's shape, color distribution, etc. When the license plate recognition system 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. The system can automatically detect vehicle entry, capture images, identify license plates, and record information. The entire process does not require human intervention, which greatly improves 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, which is helpful for subsequent management and inquiries.

[0097] In one embodiment of the present invention, the guiding system comprises:

[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 preprocessing device: The central management system receives the positioning data, stores the positioning data in the 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 to the central management system through the built-in communication module in a safe and stable manner. The server of the central management system receives the data packet from the positioning device and performs preliminary data verification and analysis to ensure the integrity and accuracy of the data. 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 query. The system cleans the stored data to remove duplicate, erroneous or invalid data to ensure the purity of the data. The system integrates the cleaned data to form a complete vehicle location information library, and performs regular or real-time data analysis to monitor the vehicle's operating status, predict traffic flow, etc. The owner initiates a route request to the central management system to the location of the vehicle through an application on a terminal device such as a smartphone or tablet computer. The central management system calls a professional map service and uses the API interface of the map service to plan the route. The map service plans the optimal driving route based on the current location of the owner and the location of the vehicle. The system displays the planned route to the owner in a graphical manner, including information such as the starting point, end point, waypoints, and estimated driving time. The car owner can choose the most appropriate driving plan to get to the location of the vehicle based on the displayed route information. The system can obtain and update the vehicle's location information in real time, ensuring that the car owner and management personnel are aware of the latest location of the vehicle at any time. The car owner can quickly check the vehicle's location through the application or web page without having to search blindly in the parking lot. The system automatically plans the best route to the vehicle for the car owner, saving time and improving travel efficiency. The system can continuously monitor the vehicle's location and immediately notify the car owner or management personnel once an abnormal situation is found (such as vehicle theft, abnormal movement, etc.). The central management system has a data backup function 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 comprises:

[0103] Vehicle departure recording system: When a 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 when it enters the parking lot, and after confirming that it is the same vehicle leaving the parking lot, 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 parking lot, and automatically calculates the fees payable based on the charging standards set by the parking lot;

[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 exit of the parking lot, the license plate recognition system installed at the exit will capture the front image of the vehicle again and apply image processing technology to identify the license plate number. The system will compare the recognized license plate number with the license plate number recorded when entering the lot to confirm that it is the same vehicle leaving the lot. This step is the key to ensuring the accuracy of the charges. Once the vehicle is confirmed to have left the lot, the system will immediately record the current departure time. The system will automatically calculate the length of time the vehicle has stayed in the parking lot based on the entry time recorded when the vehicle entered the lot and the exit time recorded now. Then, the system will automatically calculate the fees that the owner should pay based on the charging standards set by the parking lot (4 yuan / hour) and the calculated parking time. The parking lot management system will use non-stop electronic toll collection technology or electronic payment technology to send a payment request to the owner. After receiving the payment request, the owner will complete the payment operation according to the prompts. After receiving the payment information, the system will immediately confirm the payment to ensure that the payment is successful. Once the payment is successful and confirmed, the parking lot management system will automatically send a command to the barrier at the exit to lift it up and allow the vehicle to leave. Through license plate recognition technology and non-stop electronic toll collection technology, the system can quickly identify vehicles and process payments, reducing the waiting time of vehicles at the exit and improving traffic efficiency. Fast passage means that congestion is less likely to occur at the exit of the parking lot, which helps improve the surrounding traffic conditions. Car owners do not need to stop, get change or wait for manual payment, and can complete the payment through electronic payment, which greatly improves the convenience of payment. It reduces the waiting time of car owners at the exit and improves the satisfaction of the parking experience. The system automatically calculates the parking time according to the time when the vehicle enters and leaves the parking lot, avoiding the error of manual timing. From vehicle identification to fee calculation to payment confirmation and barrier lifting, the entire process is highly automated, reducing the possibility of manual intervention and human error.
