the user side receives an instruction input by a user, and the instruction requests to retrieve historical diagnosis data to obtain target diagnosis data;
the user side sends the instruction to the kernel module, the kernel module retrieves a local database according to the instruction, if the target diagnosis data is obtained through retrieval, the target diagnosis data is provided and a flow is recorded and terminated, and if the target diagnosis data is not obtained through retrieval, the following steps are continued;
the kernel module inquires whether the terminal equipment associated with the target diagnosis data is online, if not, reports that the target diagnosis data cannot be provided and terminates the process, if so, the kernel module requests the terminal equipment associated with the target diagnosis data to upload an associated file associated with the target diagnosis data, and continues the following steps;

Before the flow is terminated, the kernel module records a retrieval process as an operation record and stores the operation record to the database module.
According to some preferred embodiments of the present invention, the online service of the system is triggered by the data upload of the terminal device in a subscription and publishing mode. The client subscribes the online service by establishing connection with the server and sending a request, and after the kernel module of the system acquires the information through the user interface module, the terminal interface module of the current system of the user receives real-time diagnosis data uploaded by the vehicle-mounted terminal, and then the terminal interface module transmits the information and data content to the kernel module; the kernel module forwards the data to the inference engine module and issues the diagnosis result returned by the inference engine module to the client subscribing to the online service.
Preferably, the offline service of the system is driven by a user request. After the kernel module obtains the offline service request (querying historical data, querying user operation records, etc.) of the user through the user interface, the kernel module queries a database according to the requirement of the user, or accesses the terminal through the terminal data field to obtain the information requested by the user. Taking the historical diagnostic data queried by a terminal (such as an onboard controller of a vehicle) for a certain period of time as an example, the workflow of the kernel module in providing offline service is shown in fig. two. And the kernel module searches the local database in sequence after acquiring the data retrieval requirement, and tries to acquire the target data from a local storage area of the online terminal if the target data cannot be acquired. And if the information still cannot be acquired or the target terminal is not on line, reporting the retrieval failure to the user. The entire search process will be recorded in the user database. Besides historical data query, the system can also provide offline services including operation record query, server list query and the like, and the working flows are similar and are not described again.
Preferably, the kernel module of the system also takes charge of the database access proxy function of each interface module, and when each interface module reports important "events" (such as connection establishment, connection loss, new server online, etc.) to the kernel module according to the function requirements, the kernel module updates the events to the corresponding positions in the database.
While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that these are by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
