Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle charging, and in particular to a method and system for implementing plug-and-charge of charging piles based on a distributed electric soft bus. Background Art

[0002] With the increasing popularity of new energy vehicles, the demand for intelligent charging stations is growing. Currently, charging service systems provided by charging operators primarily utilize AC charging stations in conjunction with charging apps. Traditional QR code scanning charging methods require users to complete multiple steps, including plugging in the charger, opening the app, scanning the QR code, and confirming the connection. This results in complex interactions, low efficiency, and a poor user experience.

[0003] To improve the user experience, existing technologies have introduced a "plug and charge" feature. Users need to bind their payment method and verify vehicle information (such as entering the license plate number and uploading the driving license) in the app. They can choose "camera recognition" or "VIN code recognition." However, this solution has the following drawbacks: (1) Camera recognition is greatly affected by the parking lot network environment. In scenarios such as morning rush hour, bandwidth pressure is high and processing delay is high, which leads to the risk of recognition failure or misidentification. (2) Some public charging stations do not have screens, which makes the “VIN code recognition” function unusable, limiting the applicability of scenarios. Summary of the Invention

[0027] In some embodiments, locating the root cause and triggering a corresponding treatment mechanism includes: If it is determined that the VIN code of the driving license is incorrectly recognized, the user is requested to re-upload the driving license photo and update the user information mapping table, or switch to the code scanning charging mode; If it is determined that the parking position is abnormal and the license plate recognition error occurs, the user will be notified to re-park and take a new photo, or switch to the code scanning charging mode.

[0028] In some implementations, the user information mapping table includes an association between a VIN code, a bound payment account number, a target license plate number, and user account information.

[0029] In some embodiments, the process of building an ad hoc network of charging piles and Dianhong cameras includes: The charging pile broadcasts a discovery message containing the networking identifier and parameters; The Dianhong camera responds to the message and completes the identity authentication; A two-way data link is established after negotiating the network topology, transmission protocol and encryption method.

[0031] In some embodiments, the distributed soft bus includes a task bus and a data bus. The task bus is used to transmit messages and bytes with high reliability and latency requirements, and the data bus is used for high-throughput file transmission and stream transmission.

[0032] Another embodiment of the present invention also provides a plug-and-charge system for charging piles based on a distributed Dianhong soft bus, including a charging server, a charging pile and a Dianhong camera. The charging pile and the Dianhong camera are respectively connected to the charging server through a distributed soft bus. The charging pile and the camera build an ad hoc network through the distributed soft bus for command interaction and image transmission.

[0033] In some embodiments, the charging pile is used to detect charging interface connection events, read VIN codes and execute charging instructions; the Dianhong camera is used to receive self-organizing network instructions and photograph license plates; the charging server is used to store user information mapping tables, compare the target license plate number corresponding to the VIN code with the reference license plate number, and control the charging process according to the comparison results; the distributed soft bus is used for data transmission between the charging pile, the Dianhong camera and the charging server, and for self-organizing network communication between the charging pile and the Dianhong camera.

[0034] Implementation Case 1: The method for implementing plug-and-play charging of charging piles based on the distributed Dianhong soft bus includes: The charging pile detects the vehicle charging interface connection event, reads the vehicle VIN code, and sends a gun plug event message carrying the VIN code to the charging server through the soft bus task bus; Based on distributed soft bus networking technology, a self-organizing network is built between the charging pile and the Dianhong camera in the corresponding parking space, and the Dianhong camera is notified to take a picture of the license plate; The Dianhong camera receives shooting instructions through the self-organizing network, captures the license plate image, and sends the visual network data carrying the pile identification to the charging server through the data bus of the distributed soft bus; The charging server queries the pre-stored user information mapping table based on the VIN code to obtain the target license plate number, identifies the reference license plate number in the visual network data, and compares the target license plate number with the reference license plate number; If the comparison result is a match, the charging server sends a charging instruction to the charging pile, the charging pile starts charging and provides feedback, and the charging server billing system starts charging; If the comparison result is a mismatch, the charging server will perform root cause location. If it is determined that the VIN code of the driving license is incorrectly recognized, the user will be requested to re-upload the driving license photo and update the user information mapping table, or switch to the scan code charging mode; if it is determined that the parking position is abnormal and the license plate recognition error is caused, the user will be notified to re-park and re-photograph, or switch to the scan code charging mode.

[0035] Implementation Case 2: The plug-and-charge method for charging piles based on the distributed electric Hong soft bus includes: S1: The first charging pile in the first charging parking space detects the connection event of the charging interface of vehicle A through the charging gun, reads the first VIN code of vehicle A, and sends a first gun connection event message carrying the first VIN code to the charging server through the task bus in the soft bus; at the same time, S2. The first charging pile builds a first self-organizing network between the first electric camera of the first charging parking space and the first charging pile based on the soft bus networking technology in the distributed soft bus technology architecture, and notifies the first electric camera of the first charging parking space to perform the license plate shooting operation through the first self-organizing network; The process of self-organizing the network between the charging pile and the Dianhong camera is as follows: Device discovery: After the charging pile detects a vehicle connection event, it broadcasts a network discovery message via wireless signals (such as WIFI, Bluetooth Mesh, ZigBee, or dedicated wireless protocols) based on soft bus networking technology. After receiving the broadcast message from the charging pile, the Dianhong camera parses the network identifier (such as the unique identifier of the first charging parking space) and network parameters (such as encryption method, communication frequency band) and returns a response message to the charging pile, declaring itself available. Identity authentication and parameter negotiation: Both parties complete identity authentication through methods such as pre-shared keys, and negotiate to determine parameters such as network topology (such as star), transmission protocol (such as MQTT), and encryption method; Connection establishment: The charging pile assigns a node ID to the Dianhong camera, establishes a two-way data link, and completes the self-organizing network construction after testing the network connectivity; Network maintenance: Both parties confirm their online status through periodic heartbeat packets, and automatically switch communication modes to maintain the connection when signal interference occurs; S3, the first electric camera of the first charging parking space receives the notification message through the first ad hoc network, captures the license plate number of the currently parked vehicle A to form a first license plate image, and sends the first electric camera network data carrying the first license plate image and the pile identification to the charging server through the data bus in the soft bus; Figure 3 As shown in the figure, the distributed soft bus is divided into task bus and data bus. The task bus transmits a small amount of data but has high reliability and latency requirements, including message transmission and byte transmission. The data bus builds high throughput and large bandwidth transmission capabilities, including file transmission and stream transmission. S4. The charging server receives a first plug-in event message carrying a first VIN code from a first charging pile, and receives first Dianhong video network data carrying a first license plate image and a pile identification from a first Dianhong camera; S5. The charging server first searches the pre-stored plug-and-charge user information mapping relationship table using the first VIN code to obtain the target license plate number corresponding to the first VIN code pre-registered in the mapping relationship table; and, based on the pile identifier, finds the first license plate image in the first electric Hongshi network data, performs a license plate number image recognition operation, and obtains a reference license plate number. S6. Compare the target license plate number with the reference license plate number to obtain a comparison result; If the comparison result is a match, a start charging instruction is sent to the first charging pile. After receiving the instruction, the first charging pile starts charging and returns a charging start success notification message to the charging server. The charging server billing system starts charging and sends the billing information to the user's mobile phone charging app for real-time display; If the comparison result is a mismatch, the root cause positioning operation is performed; if it is determined that the VIN code in the driving license photo is recognized incorrectly, the user is requested to re-upload a clearer driving license photo and update the plug-and-play charging user information mapping relationship table; if it is determined that the license plate recognition error is caused by an abnormal parking position, the user is notified to re-park and control the First Electric Hong camera to re-shoot, etc.; it can also be directly switched to scanning code charging and other methods.

[0036] The plug-and-charge system for charging piles based on the distributed Dianhong soft bus includes a charging server, a distributed soft bus, a charging pile, and a camera. The charging pile and the camera communicate with the charging server through the distributed soft bus, and an ad hoc network is built between the charging pile and the camera through the distributed soft bus.

[0037] Obtaining the target license plate number through the VIN code: When the vehicle charging port is connected to the charging gun, the charging server receives the first gun plug-in event message from the charging pile through the distributed soft bus. The first gun plug-in event message includes the VIN code of vehicle A and the charging pile identifier. The charging server queries the preset plug-and-play user information mapping relationship table based on the received VIN code to obtain the target license plate number. Obtaining a reference license plate number by recognizing the license plate image through the Dianhong camera: When the vehicle is connected to the charging port, the charging pile and the Dianhong camera form an ad hoc network. The charging pile instructs the camera at the first charging parking space to take a picture of the license plate and obtain the license plate number of the currently parked vehicle A. The charging server receives the shooting data from the Dianhong camera through the soft bus. The shooting data includes the license plate number and the charging pile logo, and performs a license plate image recognition operation to obtain the reference license plate number. The VIN code recognition and license plate recognition methods are combined and used. The preset plug-and-play user information mapping table includes the VIN code, user account information and the target license plate number corresponding to the VIN code; the target license plate number is obtained through the VIN code recognized by the charging pile and the plug-and-play user information mapping table, and the target license plate number is compared with the reference license plate number recognized by the Dianhong camera; if the comparison is successful, the charging server sends a charging instruction to the corresponding charging pile logo, instructing the charging pile to start charging, and returns a charging success notification message to the server. The server billing system starts billing and sends the billing information to the user's mobile phone charging APP for real-time display; if the comparison is unsuccessful, the specific reason is determined and corresponding processing is performed.
