It should be understood that the azimuth or positional relationship is based on the azimuth or positional relationship shown in the drawings. These directional terms are used only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and thus should not be construed as limiting the present application.
Referring to fig. 1, in an embodiment of the present invention, the method includes the following steps:
S1, issuing a user password for a recharging user;
After the user connects the charging gun with the charging pile, a user password is issued to the user through the charging pile. The user password may be a combination of numbers, letters, symbols, etc., or may be in the form of a two-dimensional code, a bar code, etc. For example, the charging post may present the user password to the user by way of a built-in display, voice prompt, mobile phone application, and the like. The user needs to input a correct user password to start charging, so that unauthorized people can be effectively prevented from using the charging pile.
S2, after the user password passes verification, the charging data and the identity information of the recharging user are encrypted once and uploaded to an edge computing node;
The recharging user performs identity verification based on the user password, so that the data such as the identity, the account number and the like are prevented from being stolen, and after the recharging user passes the user password verification, the recharging data and the identity information operation authority are obtained. It should be noted that doing so may increase the security and privacy of the data while also reducing the energy consumption and delay in the data transmission process.
For example, the charging stake may encrypt the charging data and the identity information using an asymmetric encryption algorithm, and then upload the encrypted data to the edge computing node using a communication module built into the charging stake. The edge computing node may decrypt the received data using the same asymmetric encryption algorithm and process and store the data.
The charging stake can also compress and package the data prior to uploading the data to reduce the amount and time of data transmission. Meanwhile, the charging pile can also check and backup the uploaded data so as to ensure the integrity and reliability of the data.
By encrypting the uploaded charging data and identity information, the privacy and the data safety of the user can be protected, and the utilization rate and the operation efficiency of the charging equipment are improved. The edge computing node receives and stores the metering of the charging electric quantity and the calculation result of the electric charge in real time, and the charging information, and is used for formulating an ordered charging control strategy (such as the charging sequence, a specific charging time period in a day, or an electric vehicle charging power curve).
It should be noted that the edge computing node in this embodiment is a computing mode that pushes computing and data processing capabilities towards the network edge, and has several advantages over the traditional cloud computing mode:
Low delay: the edge calculation places the computing resource at a position closer to the terminal equipment, so that data processing and decision making can be performed locally, and the delay of data transmission is reduced. This is important for application scenarios requiring real-time response and low latency, such as intelligent transportation, industrial automation, and virtual reality.
Data privacy and security: the edge calculation can process and store the data locally, so that the risk of the data in the transmission process is reduced. Sensitive data can be processed on the edge equipment, and only the processing result is transmitted, so that the privacy and the safety of the data are improved.
Bandwidth utilization: the edge calculation can perform data processing and analysis locally, and only transmits the result or abstract to be transmitted to the cloud, so that a large amount of data transmission is reduced, and bandwidth resources are saved. Offline support: the edge calculation can continue to perform local calculation and decision under the condition of network disconnection or network instability, and is independent of cloud connection.
Elasticity and scalability: the edge calculation can dynamically allocate the calculation resources according to the requirements and flexibly adjust according to the change of the application scene. The edge calculation has better elasticity and expandability, and can adapt to application requirements of different scales and complexity.
S3, after receiving the charging data, the edge computing node performs secondary encryption on the charging data by combining with the identity of the edge computing node and links the charging data;
Specifically, after receiving the charging data, the edge computing node can carry out secondary encryption on the charging data by the identity of the edge computing node, so that the security of the data can be improved, and the data is ensured not to be accessed or tampered by an unauthorized third party in the transmission and processing processes. The specific implementation may vary depending on the encryption algorithm used and the particular application scenario.
For example, the edge computing node may encrypt the charging data using its identity as an encryption key using a symmetric encryption algorithm (e.g., AES) or an asymmetric encryption algorithm (e.g., RSA). The encrypted data may be stored or processed prior to transmission to the cloud or other computing node to ensure the security of the data.
In identity-based cryptography, each edge device has a unique identity, such as an email address or a mobile phone number, from which the public and private keys of the device can be generated. And after receiving the charging data, the edge computing node performs secondary encryption on the charging data by combining the identity of the edge computing node.
It should be noted that the uplink characterizes that the state, the use condition, the geographical position and other information of the charging pile and the charging parking space are uploaded to the blockchain in the form of data to form a tamper-proof data record. It has the following advantages:
(1) Data transparency is improved: the data on the block chain is transparent to all participant disclosures, and can effectively prevent data counterfeiting and cheating.
(2) Enhancing data security: the blockchain technology has the characteristics of decentralization and non-falsification, and can effectively protect the authenticity and privacy of data.
(3) The operation efficiency is improved: through intelligent contract, can realize functions such as automatic charging, intelligent fortune dimension, improve the operation efficiency of filling electric pile and charging parking stall.
(4) Optimizing resource configuration: through the real-time supervision charging stake and the condition of use of parking stall that charges, can realize the optimal configuration of resource, improve charging equipment's utilization ratio.
S4, other nodes on the chain decrypt after receiving the secondarily encrypted data, and verify the identity information of the recharging user;
Other nodes in the chain may use the same identity as the edge computing node as a decryption key to decrypt the encrypted data using a symmetric encryption algorithm (e.g., AES) or an asymmetric encryption algorithm (e.g., RSA). The decrypted data includes the identity information of the recharging user and the charging data, and the node can verify whether the identity information of the recharging user accords with the identity identification of the recharging user on the chain.
If the verification is passed, other nodes on the chain can use the identity information of the recharging user and the charging data to perform corresponding operations, such as processing, storing or inquiring the charging data. If the verification fails, other nodes in the chain may refuse to process the data or take corresponding security measures, such as marking the data as suspicious or conducting further security audits.
S5, after the identity information of the recharging user is successfully verified, accounting is conducted based on the charging data.
Specifically, the fee that the user needs to pay is calculated based on the information of the electricity consumption, the charging time, the charging amount, and the like in the charging data. For example, the amounts of these fees are calculated by corresponding algorithms or formulas and recorded in accounts where information of the source, time, purpose, etc. of the user's recharge amount is recorded to facilitate the user's corresponding check.
It should be noted that, based on the charging data, billing is performed, so that the risk of error occurrence is effectively reduced, and meanwhile, the privacy and the safety of the charging data and the identity information can be improved, so that information leakage is prevented.
Preferably, the user password comprises at least one of a hardware entity or a software key.
For example, in a hardware entity form, a user password may be stored in a USB flash drive, smart card, or other physical device and interact with a computer or other device through a physical interface to verify the user's identity. In the form of a software key, the user password may be a key stored in the form of an electronic file, a short message authentication code, which may be copied and pasted or otherwise entered into the target device to authenticate the user's identity. It should be noted that the user password authentication described above also includes voice authentication and face recognition authentication.
Preferably, after issuing the user password to the recharging user, the charging management method further includes:
and S11, grading the recharging users based on the user passwords, wherein different grades of the recharging users correspondingly enjoy the charging rate adapted to the recharging users.
Specifically, the user is ranked according to information in the user password or a recharge record. For example, users may be classified into different levels of general users, VIP users, advanced VIP users, etc., and users of different levels may enjoy different charge rates.
For an average user, the charging power with a relatively slow charging rate can be set to avoid excessive pressure and waste on the power grid. For VIP users and advanced VIP users, a faster charge rate charge power may be set to provide a better charge experience and priority service.
It should be noted that when different levels of charging service are provided for the user, the charging is performed on the premise of the quality and safety of the charging device, and the charging rates of the different levels of charging users are performed under the rated parameters of the charging device.
Preferably, the process of encrypting the charging data and the identity information of the recharging user once specifically includes:
s21, generating a displacement blockchain digital DID by utilizing an asymmetric encryption algorithm and combining charging equipment related information;
S22, carrying out strong identity binding on the blockchain digital DID and the EID of the recharging user to form the primary encryption.
Specifically, when the charging data and the identity information of the recharging user are encrypted, a unique blockchain number DID (Decentralized Identifier) is generated by combining related information of a new energy vehicle or charging equipment by utilizing an asymmetric encryption algorithm and is strongly identity-bound with EID (Entity Identifier) of the recharging user, so that the charging data are encrypted.
For example, (1) a pair of public keys for encrypting data and private keys for decrypting data are generated using an asymmetric encryption algorithm. (2) And generating a unique blockchain digital DID by combining the related information of the new energy vehicle or the charging equipment, wherein the DID can be used as an equipment identifier for uniquely identifying the equipment identity. (3) And carrying out strong identity binding on the DID and the EID of the recharging user, and realizing the association between the equipment and the citizen identity. (4) And encrypting the charging data by using the public key to ensure the safety of the data. (5) Under the condition that identity authentication is needed, the encrypted data is decrypted by utilizing a private key, and the source and the equipment identity of the data are verified.
The encryption mode can improve the security of the charging data and ensure that the data is not accessed or tampered by an unauthorized third party in the transmission and processing processes. Meanwhile, through strong identity binding with the EID of the recharging user, the association between the equipment and the identity of the recharging user can be realized, and the safety and privacy protection of charging data are improved.
Preferably, the charging data of the recharging user includes charging power, input voltage, output voltage, charging mode, charging billing and charging duration.
The charging power, the input voltage, the output voltage, the charging mode, the charging billing and the charging duration are attribute information of common charging equipment, and based on the charging information, the power consumption condition of the charging equipment can be accurately counted, so that the related charging cost can be counted and analyzed.
Preferably, the identity information includes: user name, account number, nickname, avatar, number, and mailbox.
User name, account number, nickname, avatar, number and mailbox are common identity information that often have a one-to-one correspondence with the identity of the user, and may specifically characterize or represent the user. It should be noted that when the identity information is verified or checked, several information are often used to verify at the same time, for example, when the name, account number, and mobile phone number of the user are consistent with the stored information, the identity of the recharging user can be confirmed to be correct.
The account is characterized in that a recharging user recharges the account on a certain platform or system; nicknames characterize the names that recharging users use on a charging network and can be used to identify the identity of the user. The avatar may also sometimes be used to confirm the identity of the user, as it is a representation of the user's personality and also helps other users identify their identity. When the information is charged on the charging pile, the identity information of the user can be acquired and verified in a mode of user input or automatic system acquisition, so that the safety and the legality of the charging process are ensured.
Preferably, after receiving the charging data, the edge computing node further comprises:
and S31, calculating the electric charge in real time based on the charging time and the charging power, and measuring the charging electric quantity.
Specifically, the charging time and the charging power are measured by a timer and a power meter built in the charging stake. The charging time may be measured in hours or minutes and the charging power may be calculated by measuring the current and voltage.
In calculating the electricity in real time, the electricity rate unit price, the charging time, and the measurement value of the charging power may be used for calculation. During the charging process, the charge amount can be measured to confirm the charge the user needs to pay.
In combination with the metered charge power, the recharging user may observe the current power situation of the electric vehicle, for example, by displaying the current electric vehicle power specifically on a vehicle display screen or a mobile phone software associated therewith.
Preferably, the charging management method further includes: and adjusting the charging time length and the charging power based on the control command of the recharging user.
In addition to calculating the electricity rate and metering the charge amount in real time based on the charge time and the charge power, the charging stake may receive control commands from a recharging user, which may include instructions to adjust the charge duration and the charge power. For example, the user may remotely stop charging, or reduce charging power, through a cell phone application.
After receiving the control command of the user, the mobile phone application program sends out a control data command, so that charging can be stopped remotely according to the control data command, or charging power can be reduced, and the requirement of the user can be met.
As shown in fig. 2, the embodiment of the present invention further provides a charging management system 100 based on edge computing, where the charging management system 100 includes an obtaining module 110, an encrypting module 120, an edge computing module 130, and a decrypting module 140, where the obtaining module 110 is configured to obtain charging data and identity information of a recharging user after the user password of the recharging user is verified, the encrypting module 120 is configured to encrypt the charging data and identity information of the recharging user once, the edge computing module 130 is configured to receive the data after the primary encryption, encrypt the charging data twice in combination with the identity identifier thereof, and perform decryption after receiving the data after the secondary encryption, and verify the identity information of the recharging user, where the edge computing module is further configured to log the charging data.
Specifically, after the user connects the charging gun with the charging pile, a user password is issued to the user through the charging pile, and when the user password of the charging user passes verification, the obtaining module 110 obtains charging data and identity information of the charging user. The charging data of the recharging user comprise charging power, input voltage, output voltage, a charging mode, charging billing and charging duration. The identity information includes: user name, account number, nickname, avatar, number, mailbox, etc. Because the recharging user performs identity verification based on the user password, the data such as the identity, the account number and the like are prevented from being stolen, and after the recharging user passes the user password verification, the charging data and the identity information operation authority are obtained.
The encryption module 120 encrypts the charging data and the identity information by using an asymmetric encryption algorithm and uploads the encrypted data to the edge computing node. For example, when encrypting the charging data and the identity information of the recharging user, the encryption module 120 generates a unique blockchain number DID (Decentralized Identifier) by using an asymmetric encryption algorithm and combining related information of the new energy vehicle or the charging equipment, and performs strong identity binding with EID (Entity Identifier) of the recharging user, thereby implementing encryption operation on the charging data.
After the edge computing node receives the charging data, the edge computing module 130 performs secondary encryption on the charging data by combining with the identity of the edge computing node, so that the security of the data can be improved, and the data is ensured not to be accessed or tampered by an unauthorized third party in the transmission and processing processes.
The other nodes in the chain may use the same identity as the edge computing node as a decryption key, e.g., after the decryption module 140 receives the twice-encrypted data, the encrypted data is decrypted by an asymmetric encryption algorithm. If the identity information of the recharging user is verified to be consistent with the identity mark of the recharging user on the chain at the node, and the identity information of the recharging user is verified to be consistent, the decryption is successful, and the decrypted data comprise the identity information of the recharging user and charging data.
The edge calculating module 130 calculates the fee to be paid by the user based on the information of the power consumption, the charging time, the charging amount, etc. in the charging data.
