Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0031] Example 1

[0032] Reference Figures 1 to 8 This is the first embodiment of the present invention, which provides a charging pile message acquisition device, comprising an acquisition module 1, which includes a CAN connector 11 and a FLASH memory 12. The CAN connector 11 is used to acquire message data, and the FLASH memory 12 is used to receive message data from the CAN connector 11. An analysis module 2 receives and processes message data from the FLASH memory 12. A storage module 3 includes an SD card 31, which is divided into a full message storage partition 311 and an abnormal message storage partition 312. The full message storage partition 311 receives all message data processed by the analysis module 2, and the abnormal message storage partition 312 receives abnormal message data processed by the analysis module 2. A voltage regulator module 4 provides a DC regulated power supply for the acquisition module 1, the analysis module 2, and the storage module 3.

[0033] Acquisition Module 1: Acquisition Module 1 collects message data from the charging pile. This message data includes data from the charging pile's power supply, message data from the control motherboard, and message data from the charging components.

[0034] CAN Connector 11: The terminals of CAN connector 11 establish a physical connection with the CAN bus inside the charging pile via a connecting cable, collecting message data during the charging pile's operation. This data may include message data generated during the charging handshake phase, charging parameter matching phase, charging phase, and charging completion phase.

[0035] FLASH memory 12: FLASH memory 12 serves as a temporary storage area, used to quickly receive all message data collected from the CAN connector 11 and transfer the received message data to the SD card 31, improving data processing efficiency. This flash memory contains all message data to facilitate rapid transfer of message data.

[0036] Analysis Module 2: During the process of transmitting message data from FLASH memory 12 to SD card 31, analysis module 2 processes and analyzes all message data, copies abnormal message data, and transmits it to the relevant location on SD card 31. This analysis can separate and copy abnormal data, helping staff quickly identify faults.

[0037] Storage Module 3: Storage Module 3 stores all message data processed by Analysis Module 2 and copies any abnormal data, storing the copied abnormal message data in the corresponding location within Storage Module 3. This partitioned storage method not only stores all message data but also copies and stores abnormal data, facilitating the retrieval of different message data by staff.

[0038] Through this interaction, the CAN connector 11 and the FLASH flash memory 12 jointly ensure the speed and accuracy of the collected message data. During the message data transmission process, the analysis module 2 copies and extracts abnormal data to quickly identify the fault information of the charging pile. Through different storage partitions, it can also provide convenience for personnel to review faults and improve work efficiency.

Each interface is used to extract message data for a different module. When in use, the message acquisition function is activated, and different channel switches are selected to acquire data from the three different modules simultaneously, or one or two modules can be acquired at a time. This allows for selective acquisition, reducing workload and improving work efficiency.

During the transmission to the SD card 31, the processing chip U8 processes and analyzes the message data.

[0051] Based on the data processing results, the processing chip U8 controls other electronic components such as the SD card, 4G module, and USB to implement business logic control. The processing chip U8 copies abnormal data and stores it in the abnormal message storage partition 312.

[0052] This process ensures that during the transmission of message data to the SD card 31, the transmitted message data is processed and analyzed to identify abnormal message data information and store it in the abnormal message storage partition 312.

[0059] SD Card 31: Storage device that partitions the collected message data for efficient storage, export and management of message data.

[0060] Full message storage partition 311: Stores all collected message data as data samples for analyzing the operating status or performance tracing of charging piles, ensuring data integrity and facilitating subsequent operations such as message data extraction and querying.

[0061] Abnormal message storage partition 312: Stores abnormal message data to help staff quickly identify fault information.

[0062] LCD screen 32: It can display message data, making it easy for staff to intuitively see the fault information of the charging pile.

[0063] USB: Universal Serial Bus, is a serial port used to connect computers and external devices. In message data acquisition circuits, the USB interface may be used for data transmission, device connection, etc.

[0064] 4G module: Communication unit used for remote data transmission and information sending. In the message data acquisition circuit, it enables the remote transmission of message data to the cloud, facilitating data monitoring by back-end staff.

[0065] This process enables the differentiation and storage of abnormal data, and the transmission of data through different methods, making it easier for staff to query and improving work efficiency.

[0066] Specific features: 1. Utilizes FLASH flash memory 12 as a full-volume packet acquisition buffer to solve the problem of full-volume collection of millisecond-level packet influx; 2. Employs an offline analysis mechanism to scan, retrieve, and capture feature QR codes to filter mirrored packets, forming a storage distribution, realizing full-volume packet storage, full-volume packet export, and manual deletion and automatic overwriting storage management.

[0067] Example 5

[0068] The fifth embodiment of this utility model, which is based on the previous four embodiments, also includes fault information diagnosis when abnormal message information is stored in the abnormal message storage partition 312.

[0069] A systematic approach of "scanning + retrieving + capturing feature QR codes" is created. While copying the collected abnormal message data, the system also retrieves QR codes at key locations and compares them with the system's "abnormal message feature library" to identify abnormal messages and set system settings, thereby achieving targeted storage and distribution.

[0070] The system extracts the characteristic QR code of each abnormal message and matches the key characters of the key characteristic QR codes in the "Abnormal Message Interpretation Library" of the system. The interpretation of faults that match the characteristics, have consistent object attribute definitions, and have a high probability are extracted and written into the fault information list. The information is displayed on the LCD screen 32 in order of the time the message occurred, from most recent to oldest, so that the staff can easily judge the fault of the charging pile.

[0071] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
