It should be noted that the diagnostic data includes the maximum vehicle speed traveled by the vehicle, the output power of the driving wheel, the coolant temperature, the oil pressure, the carbon dioxide emission amount, the fuel injection pressure and the braking distance of the injector, and the like. The bus includes, but is not limited to, a K line and a CAN line. The K line is a dedicated line for data transfer between the control unit of the vehicle and the diagnostic device. The CAN line belongs to the field bus field. It is a serial communication network that effectively supports distributed control or real-time control. It is a multi-master bus. The communication medium can be twisted pair, coaxial cable or optical fiber.

Further, the diagnostic data includes the VIN of the vehicle (Vehicle Identification) Number, vehicle identification code) code to distinguish between different vehicles. The VIN code consists of 17 characters, so it is commonly known as the 17-digit code. It contains the manufacturer, age, model, body type and code, engine code and assembly location of the vehicle.

Step S20, when receiving the data request instruction sent by the server, filtering the diagnostic data according to the data request instruction to obtain data to be sent;

Step S30: Send the to-be-sent data to the server.

When the remote server needs to acquire diagnostic data of the vehicle and troubleshoot the vehicle, the server sends a data request command to the diagnostic device. When the diagnostic device receives the data request command sent by the server, the diagnostic device filters the diagnostic data according to the data request instruction, obtains data to be sent, and sends the filtered data to be sent to the The server, configured to receive, by the server, the data to be sent, and perform troubleshooting on the vehicle according to the to-be-sent data. If the server only needs to acquire data related to the engine of the vehicle, the diagnostic device removes engine-independent data of the diagnostic data of the vehicle according to the data request command, such as Diagnostic data related to the chassis, the vehicle body, and the like are filtered out, and data related to the vehicle engine is transmitted as data to be transmitted to the server.

Further, the data processing method includes:

Step a, compressing the diagnostic data to obtain the compressed diagnostic data;

Step b, storing the compressed diagnostic data.

In this embodiment, the data processing method further includes:

Step S40, analyzing the diagnostic data to obtain an analysis result;

Step S50, generating an inspection report of the vehicle according to the analysis result, and storing the inspection report.

After the diagnostic device obtains the diagnostic data, the diagnostic data is analyzed to obtain an analysis result. It should be noted that the diagnostic device may analyze the diagnostic data by using a numerical analysis method, a causal analysis method, a time analysis method, an association analysis method, or the like. The numerical analysis method analyzes the numerical variation law and the numerical variation range of the data; the causal analysis method is an analysis of the inter-relevant data response situation and the corresponding speed; the time analysis method is for the data change. The analysis of the frequency and the change period; the correlation analysis method is an analysis of the proportional relationship and the correspondence relationship between the mutually correlated data, that is, the logical relationship between several parameters.

After the diagnostic device obtains the analysis result, an inspection report of the vehicle is generated according to the analysis result, and the inspection report is stored. Further, the inspection report may be stored together with the generation of the inspection report corresponding diagnostic data, or all inspection reports generated by the diagnostic device may be stored in the same folder. It can be understood that the inspection report contains identification information to distinguish inspection reports of different vehicles. In this embodiment, the VIN code of the vehicle can be used as the identification information of the inspection report.

It should be noted that, in this embodiment, the step S40 and the step S50 are between the step S10 and the step S20. In other embodiments, the step S40 and the step S50 may also be between step S20 and step S30.

Further, the data processing method further includes:

Step c, if it is confirmed according to the inspection report that the vehicle is in a fault state, outputting prompt information, and outputting a corresponding troubleshooting method.

When the diagnostic device confirms that the vehicle is in a fault state according to the inspection report, the diagnostic device outputs a prompt message prompting the user that the vehicle is in a fault state, and outputs a corresponding troubleshooting method. The diagnostic device may prompt the user that the vehicle is in a fault state by an indicator light or a prompt tone.

It should be noted that the processing manner of different faults is pre-stored in the database of the diagnostic device. When the diagnostic device determines that the vehicle is in a fault state, the diagnostic device may find a corresponding processing manner in its database according to the fault type of the vehicle, and generate a fault elimination method. Further, the diagnostic device periodically updates the database to make the data in the database more comprehensive and complete.

Further, the diagnostic device may further send the prompt information to a mobile phone of a vehicle owner of the vehicle to prevent the vehicle owner from failing to know in time that the vehicle is in a fault state. The diagnostic device may send the prompt information to the owner's mobile phone by using a short message or a voice.

Further, the data processing method further includes:

Step d, obtaining an inspection report corresponding to the to-be-sent data;

The step S30 includes:

Step e: Send an inspection report corresponding to the to-be-sent data and the to-be-sent data to the server.

Further, when the diagnostic device obtains the to-be-sent data, the diagnostic device acquires an inspection report corresponding to the to-be-sent data, and the inspection report corresponding to the to-be-sent data is sent together with the to-be-sent data Sent to the server. When the server receives the to-be-sent data and the inspection report, the server may regenerate an inspection report according to the to-be-sent data, and analyze two inspection reports to obtain the most suitable vehicle. The inspection report of the actual situation. The server may also check the inspection report with the to-be-sent data to determine whether the inspection report is incorrect, and improve the correctness of the inspection report.

In this embodiment, by analyzing the acquired diagnostic data, an analysis result is obtained, an inspection report is generated according to the analysis result, and the inspection report is stored. When the user subsequently diagnoses the vehicle, the stored inspection report can be retrieved, and the stored inspection report can be used to comprehensively diagnose the vehicle to improve the correctness of the vehicle diagnosis.
