A host factory developer develops a diagnosis data file according to a vehicle model, adds attribute values to the Semantic fields in each diagnosis service field in the ODX diagnosis file, for example, assigns the Semantic field of 1902 XX as a READ-DTC to indicate that the diagnosis service is a code reading service, assigns the Semantic field of 22 XX as a READ-ECU-VERSION to indicate that the diagnosis service is an ECU VERSION information reading service, assigns the Semantic field of 22 XX as a READ-DATASTREAM to indicate that the diagnosis service is an ECU VERSION information reading service, and through the Semantic values, a client can clearly judge the definition of each diagnosis service and correctly find out the desired algorithm and command. In developing the diagnostic data for a data stream, a developer may add SDG information (SDG is annotation information in the ODX standard) to the diagnostic data for the commands of each data stream, an after-market identifier "after" is added to the SDG, with a default value of "true", when the car does not need to display the data stream, the value is configured as "false", the client will determine whether the data stream needs to be displayed by comparing the value of aftersample when parsing the ODX diagnostic file, through the proposal, the host factory developer can conveniently distinguish the types represented by each service in the diagnosis service, especially, the version information and data stream service which are both '22' improves the efficiency of the client side for analyzing the ODX diagnosis file, reduces the workload, and by adding an artifact value in the data stream command, whether each data stream needs to be displayed or not is intelligently judged, and the accuracy of data stream display is greatly reduced.
And a host factory developer develops the ODX file of the diagnosis data according to the vehicle type, configures the Semantic attribute value and the data stream aft value in the diagnosis service according to the actual information of the vehicle, and uploads the data stream aft value to the server. The client downloads the vehicle type diagnosis data ODX packet, determines diagnosis service according to Semantic, analyzes aftersale, and determines whether the data stream needs to be displayed, so that the display process of the whole data stream is completed:
1: and a host factory developer develops the ODX file of the diagnosis data according to the vehicle type, configures the Semantic attribute value and the data stream aft value in the diagnosis service according to the actual information of the vehicle, and uploads the data stream aft value to the server.
2: and the user starts the client, downloads the corresponding ODX diagnostic data file according to the read vehicle type information and analyzes the source file.
3: and the diagnosis service types are distinguished by analyzing the Semantic values, including version information and data stream services.
4: and analyzing the data stream algorithm command and acquiring an artifact value in the data stream command.
5: if the artifact value is false, the data stream is not displayed, otherwise the data stream is normally displayed.
6: and exiting the program.
Through the steps 1-6, the host factory developer configures the Semantic and artifact attribute values when developing the diagnostic data file, and the client can distinguish the diagnostic function of each diagnostic service representative and judge which data streams do not need to be displayed according to the two values when analyzing, so that the diagnostic efficiency is improved, the workload is reduced, and the development efficiency of the host factory is greatly facilitated.
