Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Generally, when a vehicle breaks down and needs to be maintained, due to the fact that environments of users are different, the network state may be unstable or even disconnected, and therefore a fault diagnosis report cannot be uploaded and checked in time, namely, the uploading and checking of the fault diagnosis report are affected by uncertainty of the network environment, and vehicle diagnosis efficiency and driving experience of the users are reduced.
Based on this, the method, the device and the diagnostic equipment for generating the vehicle diagnostic report provided by the embodiment of the invention can effectively alleviate the technical problems.
To facilitate understanding of the present embodiment, a method for generating a vehicle diagnostic report disclosed in the present embodiment will be described in detail first.
In a possible implementation manner, the embodiment of the present invention provides a method for generating a vehicle diagnosis report, which is applied to a diagnosis device, and the flowchart of the method for generating the vehicle diagnosis report shown in fig. 1 includes the following steps:
step S102, responding to vehicle diagnosis report generation operation when fault diagnosis is carried out on the current vehicle, and judging whether network abnormality exists in the diagnosis equipment;
step S104, if yes, obtaining the vehicle model of the vehicle, and searching the vehicle information corresponding to the vehicle according to the vehicle model;
in actual use, the fault diagnosis process is usually performed when the vehicle has a fault and needs to be repaired, and the specific repair process may be performed by a professional serviceman, such as a professional serviceman in an Automobile Sales Service 4S Shop (4S for short), or may be directly performed by a vehicle owner.
The diagnostic device generally refers to an intelligent device capable of rapidly and accurately finding out technical conditions of a vehicle, an assembly, and a mechanism and obtaining an undisrupted test of a reliable conclusion, and when a fault diagnosis of the vehicle is performed, the vehicle may be diagnosed through the diagnostic device, and specifically, the diagnostic device may be communicated with an On-Board Diagnostics (OBD) of the vehicle to obtain information related to the vehicle.
Furthermore, the diagnostic device is generally configured with a network module for further uploading diagnostic content and results to the server, so that maintenance personnel can display the diagnostic content and results through a display device with an interactive interface, such as an upper computer configured in the server. However, because the environments of the diagnostic devices are different, the network state may be unstable or even disconnected, so that the content obtained by the diagnosis cannot be uploaded and checked in time.
Therefore, the above-described vehicle diagnosis report generation operation is generally an operation that is generated when a service person operates a diagnosis device, and the diagnosis device can respond to the operation and determine whether there is a network abnormality. If there is an abnormality, execution continues with step S104.
Step S106, generating an offline diagnosis report and an online diagnosis report of the vehicle based on the vehicle information, the pre-stored user information and a fault code obtained by fault diagnosis performed by the vehicle;
step S108, storing the offline diagnosis report into a first database; and storing the online diagnosis report to a second database so as to upload the online diagnosis report to a server when the diagnosis equipment network is normal.
The method for generating the vehicle diagnosis report provided by the embodiment of the invention can respond to the vehicle diagnosis report generating operation aiming at the current vehicle during fault diagnosis, and when the network abnormality of the diagnosis equipment is judged, the vehicle model of the vehicle is obtained, and the vehicle information corresponding to the vehicle is searched according to the vehicle model; generating an offline diagnosis report and an online diagnosis report of the vehicle based on the vehicle information, the pre-stored user information and a fault code obtained by fault diagnosis performed by the vehicle; and storing the offline diagnostic report to a first database; and storing the online diagnosis report into a second database so as to upload the online diagnosis report to a server for a user to check when the network of the diagnosis equipment is normal, and directly checking the offline diagnosis report stored in the first database on the diagnosis equipment, so that the user can obtain the vehicle diagnosis report under the condition of abnormal network or normal network, namely, the user can normally check the fault diagnosis of the current vehicle according to the vehicle diagnosis report under the condition of uncertain network environment, thereby effectively improving the diagnosis efficiency of the vehicle and the driving experience of the user.
In actual use, the network abnormality generally refers to a situation that the diagnostic device monitors that both the WIFI network and the mobile data are abnormal in a current environment through a network module of the diagnostic device, for example, if the diagnostic device monitors that both the WIFI network and the mobile data are not connected, a network disconnection condition is determined, if one of the WIFI network and the mobile data is available, but a received or transmitted network data flow is lower than a preset flow threshold, the diagnostic device may determine that the diagnostic device is in a weak network state at present, and may also determine that the diagnostic device is in a network abnormality. And when judging whether the diagnosis equipment has network abnormality or not, judging whether both the WIFI network and the mobile data of the diagnosis equipment are abnormal or not, if so, determining that the diagnosis equipment has network abnormality, if one network is available, not considering the network abnormality, and if not, generating a diagnosis report according to a diagnosis result and combining vehicle information and uploading the diagnosis report to a server. And if the network abnormality of the diagnosis equipment is determined, processing according to the processes of the steps S104-S108 to generate an offline diagnosis report and an online diagnosis report.
For convenience of understanding, on the basis of fig. 1, fig. 2 shows a flowchart of another vehicle diagnosis report generation method, which describes a vehicle diagnosis report generation process, and specifically, as shown in fig. 2, includes the following steps:
step S202, responding to vehicle diagnosis report generation operation when fault diagnosis is carried out on the current vehicle, and judging whether network abnormality exists in the diagnosis equipment;
step S204, if yes, reading the VIN code of the vehicle;
step S206, inquiring a vehicle model corresponding to the VIN code of the vehicle in a pre-stored local VIN code database according to the VIN code;
in specific implementation, it is described by taking an example that the diagnostic device monitors that both the WIFI network and the mobile data are not connected, that is, the diagnostic device monitors that the network is disconnected, because the diagnostic device is usually connected to an on-board diagnostic system OBD of a Vehicle, at this time, the diagnostic device may read a VIN (Vehicle Identification Number) code of the Vehicle through the on-board diagnostic system OBD, and then query a Vehicle model corresponding to the VIN code in a local VIN code database. Specifically, the diagnostic device generally has diagnostic software, such as AutoSearch software, which can further query the vehicle model in the local VIN code database after reading the VIN code, and when the network of the diagnostic device returns to normal, the diagnostic software can also perform networking to obtain the VIN code of the latest version and update the local VIN code database.
Step S208, searching vehicle information corresponding to the vehicle model in a vehicle database stored in advance based on the vehicle model;
step S210, acquiring a preset diagnosis report template;
step S212, adding the vehicle information, the user information and the fault codes obtained by fault diagnosis performed by the vehicle to a diagnosis report template so as to generate an offline diagnosis report and an online diagnosis report of the vehicle based on the diagnosis report template;
in specific implementation, after the diagnostic device identifies the vehicle signal, it may further obtain vehicle information corresponding to the vehicle type, such as system parameters, fault codes, data streams, and the like of the current vehicle, from a vehicle database according to step S208, and then integrate the vehicle information, user information, and corresponding fault codes, where the user information generally refers to information of the vehicle owner, such as name of the vehicle owner, a mobile phone number, and the like, so as to generate an offline diagnostic report and an online diagnostic report of the vehicle based on the diagnostic report template.
Step S214, storing the offline diagnosis report into a first database; and storing the online diagnostic report to a second database;
generally, the first database refers to a local database of the diagnostic device, and the offline diagnostic report may be inserted into the local database and stored after being generated.
Further, the second database generally refers to a local directory for storing temporary file data, and since the online diagnosis report stored in the second database needs to be further transmitted to the server through the network, the online diagnosis report generally needs to be encrypted to ensure the security of file transmission.
Specifically, storing the online diagnosis report in the second database requires encrypting the online diagnosis report; the encrypted online diagnostic report is then stored to a second database. For example, the online diagnostic report may be encrypted by Base64 encryption and saved to a local directory as a file.
Step S216, if the diagnostic device is monitored to be restored to the normal network, decrypting the plurality of encrypted data packets corresponding to the online diagnostic report, and uploading the online diagnostic report obtained after decryption to a server.
In actual use, in order to ensure stability of network transmission, the online diagnostic report may be split, specifically, after the encrypted online diagnostic report is stored in the second database, the encrypted online diagnostic report may be split according to a preset data splitting rule to generate a plurality of encrypted data packets corresponding to the online diagnostic report; and then storing the plurality of encrypted data packets in an associated manner.
Wherein, the splitting rule comprises: splitting according to the report basic information, the vehicle basic information and the vehicle system information; and if the vehicle system information comprises a plurality of vehicle subsystems, performing secondary splitting processing on each vehicle subsystem, wherein after the secondary splitting processing, a splitting packet corresponding to each vehicle subsystem records a fault code of the vehicle subsystem.
For example, an online diagnostic report may be broken into encrypted packets that include three parts: report basic information, such as report type, user information, etc.; vehicle basic information, such as license plate number, mileage, etc., and vehicle system information. For example, if the current fault diagnosis result includes an engine system fault and a brake system fault, the fault code includes fault codes of the engine system and the brake system, and at this time, the vehicle system information includes two vehicle subsystems of the engine system and the brake system, and when the vehicle system information is split, the engine system and the brake system can be split respectively, and each split packet includes respective fault codes, data streams, calibration information and the like, so as to avoid unstable network transmission caused by an excessively large data packet.
Further, if it is monitored that the diagnostic device is restored to a normal network, that is, when the diagnostic device has a network, the diagnostic device starts to upload the split online diagnostic report to the server, specifically, the plurality of encrypted data packets may be decrypted, and the online diagnostic report obtained after the decryption is uploaded to the server, at this time, the offline diagnostic report in the local database may be modified and perfected according to the content returned by the server after the uploading is successful, so as to ensure that the report record of the local offline diagnostic report of the user is consistent with the record of the server.
In addition, in the process of uploading the online diagnosis report, if uploading of a certain encrypted data packet fails, the encrypted data packet is automatically uploaded again, and the encrypted data packet which is uploaded successfully before does not need to be uploaded repeatedly, so that the uploading success rate is increased, if the uploading times are up to the preset times, for example, three times, the environment where the user is located is considered to be a weak network, namely, the network is abnormal, at the moment, the uploading can be suspended, and the remaining encrypted data packets of the online diagnosis report are stored to a local directory in a file manner.
Further, if the monitored duration of the network abnormality of the diagnostic device is greater than a preset duration threshold, the offline diagnostic report in the local database, that is, the first database, may be directly displayed, specifically, the offline diagnostic report in the first database may be read at this time, and the offline diagnostic report may be displayed in a preset local webpage form.
In actual use, the initial style of the offline diagnostic report is generally the same as the style of the online diagnostic report, and a timer may be set on the side of the diagnostic device, so as to update the initial style of the offline diagnostic report periodically, for example, the diagnostic device may be set to download the style file of the online diagnostic report via internet every 24 hours and update the style file to a local database, so as to ensure that the style of the offline diagnostic report can change following the change of the style of the online diagnostic report, thereby ensuring that the style of the offline diagnostic report is consistent with the style of the online diagnostic report. In addition, through the method, users, such as vehicle maintenance personnel, can normally generate and check the vehicle diagnosis report under the condition that the network environment is uncertain.
