Description

Technical Field

[0001] The present invention relates to the field of edge computing technology, and more specifically, to an edge computing device and system for intelligent connected vehicle charging services. Background Art

[0002] A large number of vehicle terminals need to be connected to the network, and the amount of data is growing explosively every year. A large part of the data has high requirements for processing accuracy and real-time performance. The cloud server architecture in the Internet era is no longer able to cope with it. Considering the latency and privacy issues of data, cloud computing is no longer suitable for processing these data, and edge computing has emerged. In the edge computing architecture, the server is distributed and sunk to the edge, and the collected data is collected, calculated and analyzed on the side close to the terminal, and then the result data is sent to the cloud server using the gateway, which improves efficiency while reducing processing latency. The edge computing gateway integrates the gateway and edge computing mobile field devices, which can be responsible for communication with vehicle terminal devices and the cloud respectively. At present, edge computing has been widely studied and applied in the field of Internet of Vehicles. For a large number of distributed charging points, edge computing can improve the efficiency of interaction between charging equipment in the point and the background.

[0003] Contactless payment is the current trend of payment development. Literally, it means payment without any feeling, and no user participation is required throughout the process. With the breakthrough and application of technologies such as AI and image recognition, contactless payment represented by face recognition and license plate recognition has emerged in various fields. While contactless payment is gradually being used, there are also some problems that need to be solved. At present, most contactless payments are to capture image information at the payment site, upload it to the cloud backend server, and the cloud backend server will perform image recognition to confirm identity information and submit payment orders. However, in the field of charging payment, license plate image information recognition may contain user privacy, and direct transmission may cause privacy leakage. Summary of the invention

Business processing is performed according to the content of the received response message. The specific steps are as follows: Step D1, establish MQTT communication connection: use the edge gateway as an MQTT client, connect to the MQTT proxy server in the cloud through cellular technology, and establish a two-way communication channel; Step D2, publish message: When the edge gateway publishes a message to the senseless payment platform, the prepared message is organized into a data packet, which contains the vehicle ID, charging pile ID, and charging status information. The prepared message is published to the senseless payment platform using message queue technology. The charging status information includes the current status of the charging pile, the current charging status of the vehicle, the charging start time, and the charging end time; Step D3, message reception: the edge gateway subscribes to the response message issued by the contactless payment platform, and parses the received response message to extract the transaction status, payment result, and order number data; Step D4, business processing: According to the content of the received response message, the edge gateway performs corresponding business processing, including updating the order status and notifying the vehicle that the charging operation is completed.

6. The edge computing device for intelligent connected vehicle charging service according to claim 1, characterized in that: The module communicating with the charging pile monitors the status of the charging pile, receives the charging instruction sent by the order and business processing module, and feeds back the charging status information to the order and business processing module. The specific steps are as follows: Step E1, charging pile status monitoring: by communicating with the charging pile device, monitoring the current working status information of the charging pile, including idle, charging, and fault status; Step E2, receiving charging instructions: when the order and business processing module authenticates the vehicle through the VIN code and determines to start charging, the module communicating with the charging pile receives the charging instruction; Step E3, controlling the charging process: after receiving the charging instruction, the module communicating with the charging pile controls the charging pile to start the charging process and provide electric energy to the car; Step E4, charging status feedback: During the charging process, the charging status is monitored and the charging status information is fed back to the order and business processing module for business processing and convergence calculation; Step E5, exception handling: When an abnormal situation such as charging failure or communication interruption occurs during the charging process, the module communicating with the charging pile sends corresponding exception information to the order and business processing module for exception handling and remedial measures.
