and 5, the diagnostic instrument makes corresponding display according to the feedback result. And the diagnostic instrument displays corresponding fault code information according to the result fed back by the remote diagnosis system.
An automotive diagnostic instrument comprising:
the communication module is used for converting the diagnosis command into a language which can be identified by the server in a communication mode with the server and analyzing a server response instruction;
the service module is used for analyzing the basic diagnosis service; if the ODX-v file is analyzed to obtain the topology of the whole vehicle, the ODX-d file is analyzed to obtain the request and the diagnosis instruction of the diagnosis message, and the OTX file is analyzed to obtain the diagnosis service sequence of the special process;
the plug-in module is used for analyzing the basic diagnosis service and converting the diagnosis message into readable display content, multi-language display, log and Trace;
and the application module is used for basic application of the diagnostic apparatus, and realizing interface function and interpersonal interaction.
Preferably, the method comprises the following steps:
the application module calls a service module (such as reading basic information);
the service module can analyze the corresponding service module to obtain the corresponding diagnosis service parameters (such as diagnosis commands and diagnosis paths) and automatically complete the group package service; the group service is a process that the diagnostic apparatus generates a corresponding diagnostic instruction according to the currently selected function, packages and sends the diagnostic instruction to the remote diagnostic system, and all functions of the diagnostic apparatus are involved.
Calling a communication module, and sending the diagnosis command to an after-sales server in a lua script mode;
the after-sale server returns the reply command to the diagnostic instrument after processing the completion information;
after the diagnostic instrument receives the diagnostic reply, the communication module analyzes the part of information;
the service module completes package service and UDS analysis service;
the reply command comprises module basic information, data flow, configuration, IO control, special functions and the like;
feeding back the result to the corresponding service module;
and displaying the analyzed content in the application module.
Since the diagnostic instrument remotely diagnoses the vehicle, an engineer is not required to perform operations on the vehicle, which may result in some risk of misoperations, thereby requiring certain safety precautions.
The user level is divided into two levels, namely a super user and a common user;
when a common user operates the diagnostic apparatus, the current position information needs to be uploaded, and the remote diagnostic system compares the vehicle position with the user position and allows operation within a specific range.
The super user is not limited by the position, and can open the authority for the ordinary user in a time limited way so as to prevent the situation that the vehicle cannot upload the position.
Compared with the prior art, the invention has the beneficial effects that:
