Traditional charging equipment access methods have the following problems:

[0003] From the perspective of device access, there is a wide variety of charging equipment, and devices from different manufacturers differ significantly in terms of communication protocols and interface standards. This necessitates complex protocol adaptation work for charging stations when connecting new devices. Traditional device access methods often require manual configuration of network parameters, protocol adaptation, and security authentication, which are cumbersome, error-prone, and result in low device access efficiency and long access times, failing to meet the needs of rapid deployment and large-scale access. Summary of the Invention

[0007] Two-way verification is performed based on verification information and charging equipment;

[0008] After successful two-way verification, the charging device is connected to the soft bus, and a communication link is established with the charging device through an encrypted communication process.

[0009] The encrypted communication process includes:

[0010] Broadcast the smart charging station controller ID and IP address to the charging equipment;

[0011] Receive and decrypt Ciphertext 1 sent by the charging device. Ciphertext 1 is encrypted with the IP of the smart charging station controller as the key and contains the charging device ID, IP, and access system key.

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0045] In order to solve the technical problems in the prior art, the present invention will now be further described in conjunction with the accompanying drawings and embodiments:

[0046] like Figures 3 to 4 As shown in the figure, this invention discloses a method for controlling rapid access to charging equipment in intelligent charging stations based on Dianhong, including:

[0047] Receive verification information from the cloud platform. The verification information includes a group list, controller information, charging device information, and charging device connection key. The controller information and charging device information include a PIN code, the IP address and ID of the smart charging station controller and the charging device.

[0048] Two-way verification is performed based on verification information and charging equipment;

[0049] After successful two-way verification, the charging device is connected to the soft bus, and a communication link is established with the charging device through an encrypted communication process.

[0050] The encrypted communication process includes:

[0051] Broadcast the smart charging station controller ID and IP address to the charging equipment;

[0052] Receive and decrypt Ciphertext 1 sent by the charging device. Ciphertext 1 is encrypted with the IP of the smart charging station controller as the key and contains the charging device ID, IP, and access system key.

[0053] After decrypting ciphertext 1, ciphertext 2 is generated, and ciphertext 2 and charging device information are forwarded to the cloud platform;

[0054] Receive and decrypt the ciphertext 3 sent by the cloud platform after verifying that the charging device is valid, and synchronize with the cloud platform in time. Ciphertext 3 contains the charging device ID, IP and access system key confirmation information.

[0055] Multi-layer two-way encryption authentication is performed with the charging device, and a communication link is established after successful authentication.

[0056] The intelligent charging station controller includes a core controller, an authentication module, and other functional modules. The control process covers both rapid access and encrypted communication. For rapid access, a device group is created on the cloud platform. Devices are authenticated using the MQTT / MQTTS protocol. After successful authentication, the cloud platform sends information, and the intelligent charging station controller completes device verification and access.

[0057] In encrypted communication, components interact with each other through multiple rounds of encrypted messages to ensure secure data transmission and connection confirmation. This system and method enable rapid and secure access of charging equipment to smart charging stations, enhance data security through encrypted communication, improve station management efficiency, reduce the risk of unauthorized access, and achieve automatic identification, protocol adaptation, security authentication, and parameter configuration of station control and charging equipment, thereby improving equipment access efficiency and the level of intelligent station management.

[0058] In practical applications, leveraging the edge computing and IoT communication capabilities of the DeeHon system, this method enables rapid and secure access for charging devices, significantly improving access efficiency and shortening device access time. Robust authentication and encryption mechanisms enhance system security and reduce the risk of unauthorized access. With excellent scalability, it can easily accommodate a large number of newly added charging devices without requiring extensive system modifications.

[0059] In some implementations, the intelligent charging station controller establishes a local communication soft bus with the charging equipment and initiates an authentication request to the platform; two-way verification further includes:

[0060] The intelligent charging station controller verifies the PIN code, group ID, IP address, and connection key of the charging equipment;

[0061] The charging equipment verifies the PIN code, ID, and IP of the smart charging station controller. After successful verification, both parties establish soft bus communication.

[0062] In some implementations, the establishment of a communication link specifically includes:

[0063] The IP and ID of the smart charging station controller, the ID and IP of the charging device, and the access key are encrypted to form ciphertext 4 and sent to the charging device.

[0064] Receive ciphertext 6 sent by the cloud platform. Ciphertext 6 contains the confirmation information of ciphertext 5 sent by the cloud platform to the charging device and the secondary access confirmation information of the charging device.

[0065] Receive the ciphertext 8 sent by the charging device to confirm the connection. The ciphertext 8 contains the charging device ID, the smart charging station controller IP and ID, the station access confirmation information, and the secondary access permission instruction issued by the cloud platform.

[0066] After confirming that the information on the cloud platform and the charging equipment is consistent, the IP and ID of the smart charging station controller, the ID and IP of the charging equipment, and the allowed access command are encrypted into ciphertext 9 and fed back to the charging equipment.

[0067] The intelligent charging station controller broadcasts its own identification information to the charging equipment; during the first encrypted communication, the charging equipment generates ciphertext 1 based on the controller's identification information and sends it to the controller; cloud verification involves the cloud platform parsing ciphertext 1 to verify the legitimacy of the charging equipment and generating ciphertext 2; two-way authentication process: the controller and the charging equipment complete two-way identity verification through multi-layer encrypted message interaction; secure communication: after successful authentication, both parties establish a secure communication link based on dynamic encryption rules and periodically confirm the connection.

[0068] In some implementations, the access permission granted by the smart charging station controller is a value calculated using an encryption formula based on the IP and ID of the smart charging station controller and the charging equipment. This encryption formula is included in the secondary access permission instruction.

[0069] In some implementations, ciphertext 5 includes the stamped number of the charging device, the access key of the charging device, the IP and ID of the smart charging station controller, and the ID and IP of the charging device. After verifying that the information in ciphertext 5 is correct, the smart charging station controller synchronizes time with the charging device.

[0070] In some implementations, it also includes:

[0071] Monitor whether the charging equipment periodically sends ciphertext 10 to confirm the connection. The ciphertext 10 includes the charging equipment ID and IP, the smart charging station controller ID and IP, the cloud platform secondary access permission, and the time parameters on the charging equipment.

[0072] If ciphertext 10 is not received within the set time, the charging device is deemed untrusted, and the identity reconstruction process is triggered.

[0073] In some implementations, the identity reconstruction process includes:

[0074] Send ciphertext 11 to the charging device, wherein ciphertext 11 contains the initial permission message issued by the platform and the charging device ID and IP address;

[0075] The charging device is required to re-initiate the encryption authentication process.

[0076] In some implementations, the communication methods between the intelligent charging site controller and the charging equipment include, but are not limited to, Ethernet, carrier communication, and WiFi.

[0077] In some implementations, if the periodic encrypted confirmation connection and the charging device communication connection both disappear simultaneously, the charging device is considered powered off or malfunctioning, and identity verification is not performed. If the charging device is powered on, it needs to immediately send encrypted message 10. If it cannot be recognized by the smart charging station controller, the access process restarts.

[0078] Based on the same inventive concept, embodiments of the present invention also provide a system for controlling fast access to charging equipment in intelligent charging stations based on Dianhong, comprising:

[0079] The communication module is used to establish connections with the cloud platform and charging equipment, and supports Ethernet, carrier communication or WiFi.

[0080] The authentication module is used to receive verification information issued by the cloud platform. The verification information includes a group list, controller and device information, and charging device connection key. Based on the verification information, the module performs two-way authentication with the charging device.

[0081] The encrypted communication module is used to perform the following operations: broadcast the controller ID and IP address to the charging device; receive encrypted messages sent by the charging device and decrypt and perform multi-layer two-way authentication based on the key issued by the cloud platform; synchronize time with the cloud platform and the charging device to maintain the timeliness of the communication link;

[0082] The monitoring module is used to monitor the periodic encrypted messages of the charging device. If the message is not received within a timeout period, the identity reconstruction process is triggered.

[0083] like Figure 1 The system architecture diagram shown specifically includes:

[0084] 1) Transformer and charging equipment: Connected through a power circuit, the transformer provides power to the charging equipment.

[0085] 2) The intelligent charging station controller and the measurement module are connected through a communication loop. The measurement module collects the power information output by the transformer, including voltage, current and power.

[0086] 3) Intelligent charging site controller and charging equipment: connected via a communication loop, with communication methods including but not limited to Ethernet, carrier communication, and WiFi.

[0087] 4) The intelligent charging station controller and the platform communicate wirelessly via 5G / 4G / 3G / 2G.

[0088] 5) The platform and charging equipment communicate wirelessly via 5G / 4G / 3G / 2G.

[0089] like Figure 2 The diagram shown illustrates the internal structure of the intelligent charging station controller.

[0090] 1) Station Controller Core Controller

[0091] As the core hub of the intelligent charging field control system, it is responsible for coordinating and managing the work of various modules and processing various data and instructions.

[0092] 2) Identity Authentication Module

[0093] The function is to verify the identity of charging devices, users, etc., and determine whether they have legitimate access and operation permissions based on preset rules and authentication information to prevent unauthorized access.

[0094] 3) Encryption module

[0095] Encryption algorithms are used to encrypt the transmitted and stored data.

[0096] 4) Transformer Area Status Monitoring Module

[0097] In conjunction with the transformer area measurement device, it can collect transformer area power parameters in real time, such as voltage, current, and power, and monitor the operating status of the transformer area.

[0098] 5) Charging equipment interface module

[0099] It provides physical and logical interfaces for connecting to charging devices, enabling data interaction and communication with charging devices.

[0100] 6) Charging equipment status monitoring module

[0101] Continuously monitor the working status of charging equipment, including equipment operating parameters and fault information.

[0102] 7) Parameter Configuration Module

[0103] Used to set and adjust the operating parameters of the intelligent charging field controller and related equipment, such as charging power limits, voltage thresholds, and communication parameters.

[0104] 8) Northbound communication module

[0105] It is responsible for communicating with the cloud, uploading information such as site operation data and equipment status to the cloud, and receiving instructions and policies issued by the cloud and transmitting them to the core controller.

[0106] This system enables rapid and secure access for charging devices, significantly improving access efficiency and shortening device access time. Through robust identity authentication and encryption mechanisms, system security is enhanced, reducing the risk of unauthorized access. With excellent scalability, it can easily accommodate a large number of newly added charging devices without requiring extensive system modifications. It effectively solves the challenges of device access, management, and scalability in smart charging stations, optimizes resource allocation, reduces operating costs, and improves the quality and reliability of charging services.

[0107] Implementation Case 1:

[0108] like Figure 3 As shown, the specific process for connecting charging station equipment to charging equipment is as follows:

[0109] S1: Create a group on the cloud platform that includes all possible connected devices (including smart charging station controllers and charging devices).

[0110] S2: The intelligent charging station controller and charging equipment proactively initiate device authentication requests based on the MQTT / MQTTS protocol to verify their identities with the cloud platform. Simultaneously, the intelligent charging station controller and charging equipment form a local communication soft bus based on their actual local communication connection (connection methods include, but are not limited to, Ethernet and RS485). All devices on the soft bus are currently in a state of pending authentication and access.

[0111] S3: The cloud platform receives the authentication request and verifies the identity information of the smart charging station controller and charging equipment to determine whether they are qualified to access the soft bus.

[0112] S4: Once the charging device is authenticated, it reports its relevant information to the cloud platform, including but not limited to software and hardware versions, device IP address, etc. This information helps the cloud platform to identify, manage, and subsequently configure the device.

[0113] S5: After receiving the device information and confirming that the charging device's information is correct, the cloud platform proactively sends relevant information to the smart charging station controller system and the charging device. The sent information includes the corresponding group list, PIN code, IP address and ID of the smart charging station controller and the charging device, and the charging device's connection key.

[0114] S6: After receiving information from the cloud platform, the intelligent charging station controller system uses this information to verify the charging devices connected to the soft bus that have not yet been confirmed. The verification includes the PIN code, the ID and IP address of the charging device in the group, and the connection key, etc., to determine whether the charging device is a legitimate access device.

[0115] S7: After the intelligent charging station controller verifies the PIN code, ID, IP address, and connection key of the charging equipment, it connects the charging equipment to the soft bus.

[0116] S8: The charging equipment also verifies the PIN code, ID, and IP of the smart charging station controller. After confirming that everything is correct, the charging equipment allows communication between the charging equipment and the smart charging station controller through the soft bus.

[0117] like Figure 4 As shown, the specific process of encrypted communication for charging station equipment is as follows:

[0118] S10: The intelligent charging station controller broadcasts its UDP ID and IP address to the charging equipment.

[0119] S20: The charging device uses the IP address of the intelligent charging station controller as a key to encrypt its own charging device ID, IP address, and access system key, generating ciphertext 1, and sends it to the intelligent charging station controller. Simultaneously, the charging device sends its parameters (including version information, etc.) to the intelligent charging station controller.

[0120] S30: After receiving ciphertext 1, the intelligent charging station controller decrypts it to obtain the charging device ID, IP address, and access key, generating ciphertext 2. The intelligent charging station controller then sends the relevant parameters of the charging device, along with ciphertext 2, to the platform.

[0121] S40: The platform decrypts ciphertext 2 and receives information from the charging device. It then uses the ID and IP address to query the ledger information and analyze the reasonableness of the device's presence at the charging station. If the information is reasonable, the platform issues a command and response to encrypt ciphertext 3 (containing the charging device ID, IP address, and access system key confirmation information) and sends it to the smart charging station controller. The platform also checks the time with the smart charging station controller to ensure their times are consistent.

[0122] S50: The intelligent charging station controller decrypts ciphertext 3, confirms the charging device ID, IP, and access key, and encrypts the intelligent charging station controller IP, ID, charging device ID, IP, and access key to form ciphertext 4, which is then sent to the charging device.

[0123] S60: Decrypt ciphertext 4 for charging equipment, encrypt the stamped number of the charging equipment, the access key of the charging equipment, the IP and ID of the smart charging station controller, the ID and IP of the charging equipment to form ciphertext 5 and send it to the platform.

[0124] S70: After confirming that the information in ciphertext 5 is correct, the platform encrypts the charging device ID, smart charging station controller IP, ID, stamp number, and secondary access confirmation information of the charging device to form ciphertext 6, and sends it to the smart charging station controller. The smart charging station controller saves ciphertext 6 and decrypts it.

[0125] S80: After the platform confirms that the information is correct, it encrypts the charging device ID, smart charging station controller IP, ID, stamp number, and secondary access confirmation information of the charging device into ciphertext 7 and sends it to the charging device. It also checks the time with the charging device to ensure that the charging device's time is consistent with the platform's.

[0126] S90: The charging equipment encrypts the message and sends ciphertext 8, which includes the charging equipment ID, the smart charging station controller IP and ID, the station access confirmation information, and the secondary access permission instruction issued by the platform, to the smart charging station controller to confirm the connection.

[0127] S100: After confirming that the information of the platform and the charging equipment is consistent, the intelligent charging station controller encrypts the intelligent charging station controller IP, ID, charging equipment ID, IP, and the allowed access command to form ciphertext 9, and sends it back to the charging equipment.

[0128] S110: The charging device decrypts ciphertext 9, confirms that all received information is correct and that it has received access permission from the smart charging station controller (the permission is a value calculated using the smart charging station controller and the charging device's IP and ID through an encryption formula, which is included in the secondary access permission instruction), and then communicates with the smart charging station controller through this communication link.

[0129] S120: The charging device encrypts the message and combines the charging device IP, ID, and smart charging station controller IP, ID, and access permission message issued by the smart charging station controller, as well as the secondary access message issued by the platform and the time on the charging device (only the date and hour parameters are referenced) into a ciphertext. The smart charging station controller confirms the connection periodically.

[0130] S130: The intelligent charging station controller monitors whether the charging equipment periodically sends a ciphertext 10 confirming the connection to the intelligent charging station controller; if not received, proceed to S140.

[0131] S140: If the intelligent charging station controller receives an identity query message after the timeout period exceeds the maximum time limit and the charging equipment has maintained a communication connection for more than the specified time, it will consider the charging equipment untrusted, actively stop control, and issue an identity reconstruction instruction based on the first permission message issued by the platform and the charging equipment ID and IP address in encrypted form 11.

[0132] S150: After receiving and parsing ciphertext 11, the charging device jumps to S20.

[0133] In summary, after reading this invention document, those skilled in the art can make various other corresponding modifications to the technical solutions and concepts based on this invention without creative mental effort, and all of these modifications fall within the scope of protection of this invention.
