And S403, the gateway server receives the log information message reported by the vehicle, analyzes the message header information (the message header information comprises the VIN of the vehicle, the ECU code ID of the log and the vehicle end time when the log is reported), and writes the message header information into a message queue related to the specified message processing theme in the message middleware server.
S404, the log application service monitors the message processing subject message appointed by the message middleware, analyzes the log message, decompresses the message body, sequentially writes the decompressed message body into the log file (naming the log file according to the vehicle VIN, the ECU code ID and the time, and dividing the log file according to the set maximum size of a single log file), and uploads the log to the file server at regular time.
S405, the log application server stores the vehicle log reporting time, the link of a log downloading URI (Uniform Resource Identifier), the VIN number, the ECU code ID and the log writing time into a database log table.
S406, the log application server sends the decoded vehicle logs to an MQTT push server one by one.
S407, the MQTT pushing server pushes the vehicle log data to a browser-side management interface of a technical administrator who subscribes the vehicle theme message and needs to assist in troubleshooting the vehicle fault problem, and a management front-end program refreshes a log display window after receiving the related push message, so that the purpose of receiving and displaying the log reported by the vehicle side in real time is achieved, and the technical administrator is supported to filter the log information according to the text keywords, the time range, the VIN code, the ECU type and the like.

S501, the log application service checks a local database to check vehicle records, judges whether the current state of the vehicle is an online state or not, and executes the step S502 if the current state of the vehicle is the online state; if not, step S510 is performed.
S502, if the vehicle is in the online state at present, the log application service sends a log starting instruction to the online vehicle message channel through a log gateway (the message channel which is long connected with a vehicle T-BOX related TCP (Transmission Control Protocol) and the log gateway maintains the online state).
S503, the vehicle T-BOX log collection main control receives the log reporting starting instruction, analyzes the instruction (analyzes the ECU code ID list in the instruction body), sends a log opening instruction to the ECU control unit needing log reporting through an UDS (Unified Diagnostic Services) instruction, modifies the local log switch variable to be open, records the ECU code ID needing log reporting, and sets the log reporting duration (set according to fixed time).
S504, the target ECU transmits log information (including ECU code ID, timestamp is required) to the log collection master through UDS instruction.
And S505, the log collection main control program writes the received log information into a cache queue in the T-BOX memory.
S506, the log pushing reporting service reads log queue data in batch at regular time, compresses the log data, and then sends the log data to a log gateway server by using a T-BOX reporting data channel.
S507, after the log pushing and reporting service finishes the log reporting work, judging whether a local log switch variable is opened, if so, executing a step 508; if closed, go to step S509.
