Description

Technical Field

[0001] The present invention belongs to the technical field of charging station management, and in particular relates to an Internet-based charging station management system. Background Art

[0002] In the development of modern cities, the popularity of electric vehicles is gradually replacing traditional fuel vehicles, becoming an important measure to reduce carbon emissions and improve the environment. However, with the increase in the number of electric vehicles, the demand for public charging stations is also rising, resulting in new challenges in charging station management and resource allocation. Intelligent and efficient charging station management systems have gradually become a key link in urban infrastructure construction. In the process of charging electric vehicles, how to ensure the legality and safety of charging behavior is an important issue. Traditional charging management systems mostly rely on license plate recognition technology, but this method cannot completely prevent the use of other people's license plates, resulting in the electricity bill being borne by the car owner and even causing legal disputes. With the increase in the number of electric vehicles, the phenomenon of charging by using other people's identities is difficult to avoid. Most of the existing charging station charging models are fixed or simply adjusted based on time periods, which is difficult to accurately reflect market dynamics and the real-time supply and demand of charging resources. For example, during peak hours, if there is no effective price adjustment mechanism, the utilization rate of charging stations will be too high, the waiting time will be extended, resulting in uneven resource allocation, and even user dissatisfaction. At the same time, the transparency and rationality of charging electricity prices are also crucial to user experience. If users cannot clearly understand the current charging costs and the basis for fee adjustments, it will affect their trust in charging stations. Another challenge facing electric vehicle charging stations is the management of parking spaces and charging piles. Due to the long charging time, many car owners do not leave the parking spaces in time after completing charging, occupying resources and preventing other users from charging normally. This situation is particularly obvious during the peak period of charging demand, resulting in a huge waste of resources. How to effectively manage the use of charging piles and parking spaces, avoid occupying parking spaces for a long time, and ensure the rationality of parking charges is an important issue in the operation and management of charging stations. Therefore, an Internet-based charging station management system is proposed. Summary of the invention

And after querying the stored license plate number according to the received license plate number to contain the same license plate number as the received license plate number, it is used to calculate the similarity between the received face feature vector and the stored face feature vector corresponding to the license plate number, and then judge whether the similarity is lower than the similarity threshold. And after judging that the similarity is lower than the similarity threshold, it is used to set the electricity price adjustment factor to infinity, and then send the electricity price adjustment factor to the charging dynamic adjustment module. And after judging that the similarity is lower than the similarity threshold, it is used to send a warning message to the display screen. And after judging that the similarity is higher than the similarity threshold, it is used to set the electricity price adjustment factor to the default value, and then send the electricity price adjustment factor to the charging dynamic adjustment module.

[0022] The warning sign is set next to the charging pile and connected to the edge computing device network to display the prompt information after receiving it.

[0023] Furthermore, the formula used by the electricity price API interface to obtain the real-time basic electricity price is:

[0028] Furthermore, the parking space resource management includes a first microprocessor, a parking space monitoring unit, and a display screen.

[0029] The first microprocessor is electrically connected to the charging pile, and is used to detect whether the charging pile is in a discharging state.

[0046] The identity security recognition module is set in front of the charging pile to monitor the license plate number in front of the charging pile. It is also used for user face recognition and then extracting the facial feature vector of the face image.

It is also used to query whether the stored license plate number contains the same license plate number according to the license plate number. It is also used to calculate the similarity between the facial feature vector and the corresponding stored facial feature vector after querying the stored license plate number according to the license plate number to contain the same license plate number. It is also used to set the electricity price adjustment factor to infinity after judging that the similarity is lower than the similarity threshold, and then send the electricity price adjustment factor to the charging dynamic adjustment module. It is also used to prohibit any touch operation after judging that the similarity is lower than the similarity threshold. It is also used to set the electricity price adjustment factor to the default value after judging that the similarity is higher than the similarity threshold, and then send the electricity price adjustment factor to the charging dynamic adjustment module.

[0047] The dynamic adjustment module for charging costs is set in the charging station, connected to the user App, the grid API interface, and the identity security identification module network, and is used to monitor the image in the charging station, then identify the number of cars to be charged in the image, and then send it to the parking resource management module. It is also used to obtain the real-time basic electricity price of the power grid. It is also used to determine whether the electricity price adjustment factor is the default value after receiving the electricity price adjustment factor and the number of cars to be charged. It is also used to calculate the real-time charging electricity price based on the real-time basic electricity price, the number of cars to be charged, and the electricity price adjustment factor after determining that the electricity price adjustment factor is the default value, and then send it to the user App. It is also used to generate a prompt message after determining that the electricity price adjustment factor is infinite, and then display it.

[0048] The parking space resource management module is connected to the charging fee dynamic adjustment module and the user App network to detect whether the charging pile is in a discharging state. It is also used to monitor whether the parking space is occupied after the charging pile is in a non-discharging state, and to start recording the first parking duration after monitoring the parking space occupancy, and then determine whether the first parking duration exceeds the parking time threshold. It is also used to start recording the second parking duration after determining that the first parking duration exceeds the parking time threshold. It is also used to calculate the parking fee based on the second parking duration, the preset parking rate, and the number of cars to be charged after monitoring that the parking space is not occupied, and then send it to the user App. It is also used to count the unoccupied parking spaces after monitoring that the parking space is not occupied, and then display them.

[0049] In this embodiment, the identity security recognition module includes a license plate recognition device, a face recognition unit, and a server.

[0050] The license plate recognition device is installed in front of the charging pile to monitor the license plate number in front of the charging pile and then send the license plate number to the server.

[0051] The face recognition unit is set on the charging pile for user face recognition, then extracts the face feature vector of the face image, and then sends the face feature vector to the server.

[0052] The server is connected to the license plate recognition device, the face recognition unit, and the charging dynamic adjustment module network, and is used for the administrator to store the license plate number and the face feature vector corresponding to the license plate number. And after receiving the license plate number and the face feature vector, it is used to query whether the stored license plate number contains the same license plate number as the received license plate number according to the received license plate number. And after querying the stored license plate number according to the received license plate number to contain the same license plate number as the received license plate number, it is used to calculate the similarity between the received face feature vector and the stored face feature vector corresponding to the license plate number, and then judge whether the similarity is lower than the similarity threshold. And after judging that the similarity is lower than the similarity threshold, it is used to set the electricity price adjustment factor to infinity, and then send the electricity price adjustment factor to the charging dynamic adjustment module. And after judging that the similarity is lower than the similarity threshold, it is used to send a warning message to the display screen. And after judging that the similarity is higher than the similarity threshold, it is used to set the electricity price adjustment factor to the default value, and then send the electricity price adjustment factor to the charging dynamic adjustment module.

[0053] The display screen is set on the charging pile and connected to the server network. It is used to prohibit any touch operation after receiving the warning information.

[0054] In this embodiment, by using the license plate number and the facial feature vector for double verification at the same time, the security of identity recognition is improved, the risk of impersonation is reduced, the embarrassment when borrowing a car and the high risk of borrowing a car that the borrower has to bear are avoided, and the real-time data transmission of the license plate recognition device and the facial recognition unit ensures that the manager can obtain the user's identity information in real time, thereby realizing dynamic monitoring, judging the legitimacy of the user's identity based on the recognition results, and automatically adjusting the electricity price. When an unmatched identity is identified, the electricity price adjustment factor is set to infinity to prevent unauthorized users from charging, further enhancing the right to use the vehicle autonomously. When the recognition fails, the system will promptly send a warning message to the display screen and prohibit any touch operation, thereby improving the security protection level of the system. The server stores the license plate number and the corresponding facial feature vector for future query and management, ensuring the effective management of user identity information. The automated identity authentication and electricity price adjustment process reduces the user's operation steps and improves the convenience of use.

[0055] In this embodiment, the formula for calculating the similarity by the server is:

[0056] Among them, F is the received face feature vector, F regi For the corresponding stored face feature vector, similarity cos (F,Freg i ) is the similarity.

[0057] For example, the received facial feature vector is [0.2, 0.3, 0.4], and the corresponding stored facial feature vector is [0.5, 0.1, 0.3]. The similarity is calculated. cos (F,Freg i ) is 0.784,

[0058] For example, the received facial feature vector is [0.9, 0.1, 0.1], and the corresponding stored facial feature vector is [0.8, 0.2, 0.1], and the calculated similarity is 1.02.

[0059] In this embodiment, the formula for setting the electricity price adjustment factor of the server is:

[0060]

[0061] Where K is the electricity price adjustment factor and S is the similarity threshold.

[0062] For example, if the similarity is 0.784, the similarity threshold is 0.9, and the electricity price adjustment factor is ∞,

[0063] For example, the similarity is 1.02, the similarity threshold is 0.9, and the electricity price adjustment factor is the default value, which is 1.

[0064] In this embodiment, the charging fee dynamic adjustment module includes a camera, an edge computing device, an electricity price API interface, and a warning sign.

[0065] The camera is set up in the charging station to monitor the image in the charging station, then identify the number of cars to be charged in the image, and then send the number of cars to be charged to the edge computing device and the parking space resource management module.

[0066] The electricity price API interface is connected to the power grid API interface to obtain the real-time basic electricity price of the power grid, and then send the real-time basic electricity price to the edge computing device.

[0067] The edge computing device is connected to the camera, electricity price API interface, server, and user App network, and is used to determine whether the electricity price adjustment factor is the default value after receiving the electricity price adjustment factor, the number of cars to be charged, and the real-time basic electricity price. And after determining that the electricity price adjustment factor is the default value, it is used to calculate the real-time charging electricity price based on the real-time basic electricity price, the number of cars to be charged, and the electricity price adjustment factor, and then send it to the user App. And after determining that the electricity price adjustment factor is infinite, it is used to generate a prompt message and then send it to the warning sign.

[0068] The warning sign is set next to the charging pile and connected to the edge computing device network to display the prompt information after receiving it.

[0069] In this embodiment, the camera monitors the number of cars to be charged in the charging station in real time to ensure the effective use and management of charging resources and reduce the waste of idle parking spaces. The real-time basic electricity price of the power grid is obtained through the electricity price API interface, and the edge computing device can dynamically calculate the real-time charging electricity price in combination with the number of cars to be charged and the electricity price adjustment factor to ensure that users pay fair and reasonable fees. The calculated real-time charging electricity price will be quickly sent to the user App, so that users can immediately understand the changes in charging costs, so as to make corresponding decisions and improve user experience. When the electricity price adjustment factor is infinite, the system will generate a prompt message and display it through a warning sign to promptly inform users of the risks of charging operations and enhance safety awareness. Combined with the monitoring of the number of cars to be charged and the real-time electricity price information, the system can optimize the allocation of charging resources, avoid the phenomenon of concentrated charging or retention of users due to electricity price fluctuations, and improve the operating efficiency of the charging station. The integration of edge computing and real-time data processing improves the intelligent management capabilities of charging stations, enabling them to adapt to the ever-changing power grid environment and user needs.

[0070] In this embodiment, the formula used by the electricity price API interface to obtain the real-time basic electricity price is:

[0071] Among them, D(t) is the real-time basic electricity price, in yuan / kWh.

[0072] In this embodiment, the edge computing device calculates the real-time charging electricity price according to the real-time basic electricity price, the number of vehicles to be charged, and the electricity price adjustment factor. The formula is:

[0073] P=D(t)+Q×K,

[0074] Among them, P is the real-time charging electricity price, in yuan / kWh, and Q is the number of cars to be charged, in units of vehicles.

[0075] For example, during peak periods, the real-time basic electricity price is 1.5 yuan / kWh, the number of cars to be charged is 3, the electricity price adjustment factor is 1, and the real-time charging electricity price is 4.5 yuan / kWh.

[0076] In this embodiment, the parking space resource management includes a first microprocessor, a parking space monitoring unit, and a display screen.

[0077] The first microprocessor is electrically connected to the charging pile, and is used to detect whether the charging pile is in a discharging state. And after the charging pile is in a non-discharging state, it is used to generate a start signal, and then send it to the parking space monitoring unit. And after receiving the timing information, it starts recording the first parking duration, and then determines whether the first parking duration exceeds the parking time threshold.

It is also used to count the second number of vacant parking spaces from the initial number of vacant parking spaces after monitoring that the parking space is not occupied, and then send it to the display screen.

[0079] The display screen is arranged in the charging station and is electrically connected to the parking space monitoring unit, and is used for displaying the first number of vacant parking spaces or the second number of vacant parking spaces after receiving the number of vacant parking spaces.

[0080] In this embodiment, the parking space monitoring unit monitors the occupancy of the parking space in real time to ensure that the manager can understand the usage status of the parking space in a timely manner and improve the utilization rate of the parking space. The first microprocessor automatically records the parking time according to the received timing information and determines whether it exceeds the set parking time threshold, thereby realizing effective management of the parking time. After detecting that the parking space is free, the system can automatically calculate the parking fee and send it to the user through the user App, which improves the convenience of user experience. The display screen displays the first number of vacant parking spaces and the second number of vacant parking spaces in real time, which is convenient for users and managers to obtain parking space information instantly and reduce the time to find parking spaces. By displaying the number of vacant parking spaces in a timely manner, users can quickly determine the available parking spaces in front of the charging pile, optimizing the charging experience.

It is also used to generate timing information after monitoring the parking space is occupied, and then send it to the first microprocessor and the second microprocessor. It is also used to generate clearing information after monitoring the parking space is not occupied, and then send it to the first microprocessor and the second microprocessor.

[0083] The second microprocessor is electrically connected to the ultrasonic sensor and the display screen, and is used for the manager to store the initial number of vacant parking spaces. After receiving the timing information, the first number of vacant parking spaces is subtracted by 1 from the initial number of vacant parking spaces, and then the first number of vacant parking spaces is sent to the display screen. After receiving the reset message, the second number of vacant parking spaces is added by 1 to the initial number of vacant parking spaces, and then the second number of vacant parking spaces is sent to the display screen.

[0084] In this embodiment, the first microprocessor calculates the parking fee according to the second parking time, the preset parking fee rate, the number of cars to be charged, and the preset parking fee coefficient as follows:

[0085] Charge=R×T second ×(1+β×Q),

[0086] Where T second is the second parking time, in hours, R is the preset parking rate, in yuan / hour, Q is the number of cars to be charged, in units, β is the preset parking fee coefficient, and Charge is the parking fee, in yuan.
