Description

Technical Field

[0001] The present invention relates to the field of electric vehicle charging, and specifically to a shared charging pile billing system based on the Internet of Things. Background Art

[0002] A charging pile refers to a power supply device used to provide energy for charging the battery of an electric vehicle. With the popularization of electric vehicles, the owners of electric vehicles need to obtain diverse charging channels for electric vehicles. In particular, for some owners without a parking space who do not support the installation of private charging piles, there is an urgent need for shared charging piles to provide energy for electric vehicles.

[0003] In the prior art, shared charging piles often require the owner to drive the vehicle manually to the charging pile to charge the electric vehicle, and the charging cannot be automatically terminated and must be manually stopped by the owner. Moreover, the management of charging vehicles is chaotic and the billing is unclear. There are often vehicles parked at the shared charging piles for an extremely long time, occupying positions and reducing the efficiency of the shared charging piles. How to achieve the automatic management of vehicle charging and improve the efficiency of shared charging piles is a problem that needs to be solved. For this purpose, a shared charging pile billing system based on the Internet of Things is provided herein. Summary of the Invention

[0004] The purpose of the present invention is to provide a shared charging pile billing system based on the Internet of Things.

[0005] The purpose of the present invention can be achieved through the following technical solutions: A shared charging pile billing system based on the Internet of Things includes a control center, and the control center is connected to a user management module, a vehicle management module, and a charging pile billing module.

[0006] The user management module is used for user registration and login to manage the account, and the process includes:

[0007] A registration unit and a login unit are set up for users to register an account and log in.

[0008] The user inputs the user's personal basic information through the registration unit.

[0009] The registration unit uploads the user's personal basic information input by the user to the control center for review. After the review is passed, the user's account number, login password, and user wallet are generated and uploaded to the database; the account number and login password are sent to the user client.

[0010] The user completes the login by inputting the account number and login password through the login unit.

[0011] When the user logs in for the first time, a bank card needs to be bound to the user wallet for the user to transfer money into the user wallet.

[0012] The vehicle management module is used for the management of vehicle charging, and the process includes:

[0013] Set up a vehicle identification sub-module, a vehicle charging queuing sub-module, and a vehicle handling sub-module; the vehicle identification sub-module is used to obtain the license plate number of the vehicle driven by the user, the vehicle charging queuing sub-module is used for the management of vehicle charging queuing, and the vehicle handling sub-module is used for automated vehicle handling;

[0014] The vehicle management module sets up designated parking spaces, waiting areas, charging areas, and pick-up areas;

[0015] The process by which the vehicle identification sub-module obtains the license plate number of the vehicle driven by the user includes:

[0016] The vehicle identification sub-module deploys a license plate detection model trained through a deep learning network;

[0017] Set up a group of image acquisition terminals to collect images of the vehicle to be detected after the user drives and parks the vehicle; transmit the images to be detected into the license plate detection model to identify the license plate number of the vehicle;

[0018] Match the obtained license plate number with the corresponding user account in the database;

[0019] The process by which the vehicle charging queuing sub-module manages vehicle charging queuing includes:

[0020] Set up a first sequence, a second sequence, and a third sequence for storing user accounts; among them, the accounts in the first sequence are first-class user accounts, the accounts in the second sequence are second-class user accounts, and the accounts in the third sequence are third-class user accounts; the first sequence stores at most m first-class user accounts, and m is determined by the maximum number of vehicles that can be charged simultaneously by the charging piles; the second sequence and the third sequence store the second-class user accounts and the third-class user accounts in a set order, and when the first user account exits, the other accounts in the sequence move forward one by one in turn;

[0021] Set up a vehicle charging reservation unit for the reservation user to complete the vehicle charging reservation;

[0022] The user selects the vehicle charging time through the vehicle charging reservation unit, confirms the vehicle arrival time, and marks the user as a reservation user. The user account corresponding to the reservation user is the reservation user account; at the same time, the reservation user account corresponding to the reservation user enters the third sequence and becomes a third-class user account;

[0023] When the reservation user account becomes the first in the third class, it exits the third sequence and enters the second sequence to become a second-class user account;

[0024] If the vehicle of the reservation user does not arrive at the designated parking space at the vehicle arrival time, the reservation user account exits the second sequence;

[0025] The reserved user drives the reserved user's vehicle to the designated parking space before the vehicle arrival time. After the license plate number obtained by the vehicle identification sub-module matches the corresponding reserved user account, a third instruction is sent to the vehicle handling sub-module;

[0026] After the reserved user's vehicle arrives at the waiting area, if the reserved user account is a second type of user account and the number of the first type of user accounts in the first sequence is less than m, the reserved user account exits the second sequence and enters the first sequence. At the same time, a second instruction is sent to the vehicle handling sub-module, and the reserved user's vehicle enters the charging area for charging; otherwise, no operation is performed;

[0027] The unreserved user drives the vehicle to the designated parking space. After the license plate number obtained by the vehicle identification sub-module matches the corresponding user account, a third instruction is sent to the vehicle handling sub-module. At the same time, the corresponding user account of the user enters the third sequence to become a third type of user account, and the user's vehicle arrives at the waiting area;

[0028] When the number of the first type of user accounts in the first sequence is less than m and no second type of user vehicle has arrived at the waiting area, the user account exits the third sequence and enters the first sequence to become a first type of user account. At the same time, a second instruction is sent to the vehicle handling sub-module, and the user's vehicle enters the charging area for charging; otherwise, no operation is performed;

[0029] After charging is completed, a first instruction is sent to the vehicle handling sub-module. The vehicle of the first type of user account enters the pick-up area, then exits the first sequence and waits to be picked up by the user corresponding to the vehicle;

[0030] The process of the vehicle handling sub-module automatically handling the vehicle includes:

[0031] An electric vehicle handling device is set up, specifically an AGV car carrier parking robot;

[0032] After receiving the first instruction, the vehicle handling sub-module controls the electric vehicle handling device to move the vehicle that has completed charging in the charging area to the pick-up area;

[0033] After receiving the second instruction, the vehicle handling sub-module controls the electric vehicle handling device to move the vehicle corresponding to the user account in the waiting area to the charging area;

[0034] After receiving the third instruction, the vehicle handling sub-module controls the electric vehicle handling device to move the vehicle in the designated parking space to the waiting area;

[0035] The charging pile billing module is used to complete the billing for vehicle charging. The process includes:

[0036] After the user binds the bank card, it is necessary to transfer the balance in the bank card to the user wallet to generate the user balance;

[0037] Set the vehicle charging mode, including fast charging and slow charging;

[0038] After the user drives the vehicle to the designated parking space, the user selects the vehicle charging mode;

[0039] After the electric vehicle handling device transports the vehicle corresponding to the user account in the waiting area to the charging area, it connects the user account to the control center. The control center reads the user balance in the user account and records the user balance as Y;

[0040] Set the settlement period T, and the cost required for one settlement period is S;

[0041] Both fast charging and slow charging are billed according to the settlement period. The fast charging price is recorded as S1, and the slow charging price is recorded as S2;

[0042] Mark the moment when the vehicle starts charging and billing as the initial moment, and record the initial moment as T1;

[0043] At the same time, compare the user balance Y of the user with the cost S required for one settlement period of the vehicle, that is

[0044] When Y ≤ S*T, a balance insufficient message is generated and uploaded to the control center. The control center sends the balance insufficient message to the user client; after the user transfers the bank card balance to the user balance and the user balance Y is greater than or equal to S*T, continue charging;

[0045] When Y > S*T, no balance insufficient message is generated;

[0046] Mark the current moment as T2;

[0047] Obtain the time interval duration between the initial moment T1 and the current moment T2, and record the interval time duration as ΔT;

[0048] When ΔT < T and the vehicle is in the charging state, no billing information is generated;

[0049] When ΔT < T and the user needs to end the vehicle charging, billing information is generated, that is, the charging cost is obtained. Record the charging cost as FY, where FY = S*T;

[0050] Send the charging cost FY to the control center, and the control center sends it to the user client to complete the vehicle charging; after the user confirms the cost, deduct the corresponding charging cost from the user balance, update the user balance and record the updated account balance as YG, where YG = Y - FY;

[0051] When ΔT ≥ T and the vehicle is in the charging state, generate the periodic settlement cost, record the periodic settlement cost as ZS, ZS = ΔT*S;

[0052] Update the user's account balance according to the obtained periodic settlement fee, YG = Y - ZS;

[0053] Compare the obtained account balance YG with the fee S*T required for the settlement period, and output the comparison result. If YG ≤ S*T, generate an insufficient balance message and upload the insufficient balance message to the control center, which is sent to the user client by the control center;

[0054] When YG > S*T, do not generate an insufficient balance message, and so on;

[0055] At the same time, change the current time to the initial time, that is, T2 → T1, and so on;

[0056] It should be further noted that when the vehicle is fully charged, the charging is automatically completed, and there is no need for the user to manually control to end the vehicle charging;

[0057] Set up an overtime parking charging unit; start timing after the user's vehicle completes charging and the electric vehicle handling equipment transports the vehicle that has completed charging in the charging area to the pick-up area;

[0058] Set an overtime threshold TC;

[0059] Record the start timing time as TC1, the user pick-up time as TC2, and the time interval as ΔTC;

[0060] When ΔTC ≤ TC, do not generate overtime parking charging information;

[0061] Otherwise, generate overtime parking charging information, upload it to the control center, and the control center sends it to the user client;

[0062] Set an overtime parking charging period ZT, and the overtime parking charging price is ZTS;

[0063] Deduct the corresponding overtime parking fee ZT*ZTS from the user's balance;

[0064] If the user's account balance is insufficient, deduct it to the corresponding negative value and remind the user to recharge.

[0065] Compared with the prior art, the beneficial effects of the present invention are as follows: on the one hand, it provides an automated vehicle charging mode. The user only needs to park the vehicle in the designated parking space and pick up the vehicle in the pick-up area to complete the charging, which facilitates the user's operation;

[0066] On the other hand, by setting up an overtime parking charging mechanism, users will be charged if they do not pick up the vehicle that has completed charging in time, reducing the situation that the vehicle that has completed charging occupies the pick-up area for a long time and improving the efficiency of the shared charging pile for vehicle charging. Description of the Drawings

[0067] Figure 1 This is the schematic diagram of the present invention. Detailed implementation manners

[0068] As Figure 1 shown, a charging fee system for shared charging piles based on the Internet of Things includes a control center, and the control center is connected to a user management module, a vehicle management module, and a charging pile charging fee module;

[0069] The user management module is used for user registration and login to manage accounts, and the process includes:

[0070] A registration unit and a login unit are set up for users to register accounts and log in;

[0071] Users input their personal basic information through the registration unit; it should be further noted that in the specific implementation process, the user's personal basic information includes license plate number, mobile phone number, login password, name, and gender;

[0072] The registration unit uploads the user's input personal basic information to the control center for review. After the review is passed, the user's account number, login password, and user wallet are generated and uploaded to the database; the account number and login password are sent to the user client;

[0073] Users complete the login by inputting the account number and login password through the login unit;

[0074] When users log in for the first time, they need to bind a bank card to the user wallet for transferring money into the user wallet;

[0075] The vehicle management module is used for the management of vehicle charging, and the process includes:

[0076] A vehicle identification sub-module, a vehicle charging queue sub-module, and a vehicle handling sub-module are set up; the vehicle identification sub-module is used to obtain the license plate number of the vehicle driven by the user, the vehicle charging queue sub-module is used for the management of vehicle charging queues, and the vehicle handling sub-module is used for automated vehicle handling;

[0077] The vehicle management module sets designated parking spaces, waiting areas, charging areas, and pick-up areas;

[0078] The process of the vehicle identification sub-module obtaining the license plate number of the vehicle driven by the user includes:

[0079] The vehicle identification sub-module is deployed with a license plate detection model trained by a deep learning network;

[0080] An image acquisition terminal group is set up. After the user drives and parks the vehicle, the vehicle image to be detected is collected; the image to be detected is transmitted to the license plate detection model to identify the license plate number of the vehicle;

[0081] Match the obtained license plate number with the corresponding user account in the database;

[0082] The process of the vehicle charging queuing sub-module for managing vehicle charging queuing includes:

[0083] Set the first sequence, the second sequence, and the third sequence for storing user accounts; among them, the accounts in the first sequence are the first type of user accounts, the accounts in the second sequence are the second type of user accounts, and the accounts in the third sequence are the third type of user accounts; the first sequence can store at most m first type of user accounts, and m is determined by the maximum number of vehicles that can be charged simultaneously by the charging pile; the second sequence and the third sequence store the second type of user accounts and the third type of user accounts in a set order, and when the first user account exits, the other accounts in the sequence move forward one by one;

[0084] Set a vehicle charging reservation unit for the reservation user to complete the reservation of vehicle charging;

[0085] The user selects the vehicle charging time through the vehicle charging reservation unit, confirms the vehicle arrival time, and marks the user as a reservation user. The user account corresponding to the reservation user is the reservation user account; at the same time, the reservation user account corresponding to the reservation user enters the third sequence and becomes the third type of user account;

[0086] It should be further noted that in the specific implementation process, according to the number of the three types of user accounts in the current first sequence, the second sequence, and the third sequence, estimate the time when all the currently charging and to-be-charged vehicles complete charging. The vehicle charging reservation unit only provides the time for vehicle charging reservation after adding the estimated time when all the currently charging and to-be-charged vehicles complete charging to the current time, and does not accept vehicle charging reservations more than n hours after the current time, where n is a pre-set value;

[0087] When the reservation user account becomes the first of the third type of users, it exits the third sequence and enters the second sequence to become the second type of user account;

[0088] If the reserved user's vehicle does not reach the designated parking space at the vehicle arrival time, the reserved user account exits the second sequence;

[0089] Before the vehicle arrival time, the reservation user drives the reserved user's vehicle to the designated parking space. After the license plate number obtained by the vehicle identification sub-module matches the corresponding reservation user account, a third instruction is sent to the vehicle handling sub-module;

[0090] After the reserved user's vehicle arrives at the waiting area, if the reserved user account is the second type of user account and the number of the first type of user accounts in the current first sequence is less than m, the reserved user account exits the second sequence and enters the first sequence, and at the same time, a second instruction is sent to the vehicle handling sub-module, and the reserved user's vehicle enters the charging area for charging; otherwise, no operation is performed;

[0091] When a non-reserved user drives the vehicle to the designated parking space, after the license plate number obtained by the vehicle identification sub-module matches the corresponding user account, a third instruction is sent to the vehicle handling sub-module. At the same time, the user's corresponding user account enters the third sequence and becomes a third-type user account, and the user's vehicle arrives at the waiting area.

[0092] When the number of first-type user accounts in the first sequence is less than m and the second-type user vehicles have not arrived at the waiting area, the user account exits the third sequence and enters the first sequence to become a first-type user account. At the same time, a second instruction is sent to the vehicle handling sub-module, and the user's vehicle enters the charging area for charging; otherwise, no operation is performed.

[0093] After charging is completed, a first instruction is sent to the vehicle handling sub-module. The vehicle of the first-type user account enters the pick-up area, then exits the first sequence and waits to be picked up by the user corresponding to the vehicle.

[0094] The process of the vehicle handling sub-module automatically handling the vehicle includes:

[0095] An electric vehicle handling device is set up, specifically an AGV car carrier parking robot.

[0096] After receiving the first instruction, the vehicle handling sub-module controls the electric vehicle handling device to move the vehicle that has completed charging in the charging area to the pick-up area.

[0097] After receiving the second instruction, the vehicle handling sub-module controls the electric vehicle handling device to move the vehicle corresponding to the user account in the waiting area to the charging area.

[0098] After receiving the third instruction, the vehicle handling sub-module controls the electric vehicle handling device to move the vehicle at the designated parking space to the waiting area.

[0099] The charging pile billing module is used to complete the billing for vehicle charging, and the process includes:

[0100] After the user binds the bank card, the balance in the bank card needs to be transferred to the user's wallet to generate the user balance.

[0101] Set the vehicle charging mode, including fast charging and slow charging.

[0102] After the user drives the vehicle to the designated parking space, select the vehicle charging mode.

[0103] After the electric vehicle handling device moves the vehicle corresponding to the user account in the waiting area to the charging area, connect the user account to the control center. The control center reads the user balance in the user account and records the user balance as Y.

[0104] Set the settlement period T, and the cost required for one settlement period is S.

[0105] Both the fast charging and slow charging are billed according to the settlement period. The fast charging price is denoted as S1, and the slow charging price is denoted as S2;

[0106] Mark the moment corresponding to the start of charging and billing of the vehicle as the initial moment, and denote the initial moment as T1;

[0107] At the same time, compare the user balance Y of the user with the cost S required for one settlement period of the vehicle, that is

[0108] When Y ≤ S*T, an insufficient balance message is generated and uploaded to the control center. The control center sends the insufficient balance message to the user client; after the user transfers the bank card balance to the user balance and the user balance Y is greater than or equal to S*T, charging continues;

[0109] When Y > S*T, no insufficient balance message is generated;

[0110] Mark the current moment as T2;

[0111] Obtain the time interval duration between the initial moment T1 and the current moment T2, and denote the interval time duration as ΔT;

[0115] When ΔT ≥ T and the vehicle is in the charging state, a periodic settlement cost is generated, and the periodic settlement cost is denoted as ZS, ZS = ΔT*S;

[0116] Update the user's account balance according to the obtained periodic settlement cost, YG = Y - ZS;

[0117] Compare the obtained account balance YG with the cost S*T required for the settlement period, and output the comparison result. If YG ≤ S*T, an insufficient balance message is generated and uploaded to the control center, and the control center sends it to the user client;

[0118] When YG > S*T, no insufficient balance message is generated, and so on;

[0119] Meanwhile, change the current moment to the initial moment, i.e., T2 → T1, and so on;

[0120] It should be further noted that when the vehicle is fully charged, the charging is automatically completed without the need for the user to manually control the end of the vehicle charging;

[0121] Set up an overtime parking charging unit; start timing after the user's vehicle has completed charging and the electric vehicle handling equipment has transported the charged vehicle in the charging area to the pick-up area;

[0122] Set an overtime threshold TC;

[0123] Record the start timing time as TC1, the user pick-up time as TC2, and the time interval as ΔTC;
