The vehicle related in the embodiment of the application is provided with a vehicle remote diagnosis function, and after the diagnosis equipment on the vehicle receives a corresponding instruction, the vehicle information of the vehicle can be obtained and sent out. The diagnosis device on the vehicle is a vehicle-mounted TBOX (telematics BOX), also called a TBOX terminal, and is mainly used for acquiring vehicle information of the vehicle and then transmitting the acquired vehicle information in a wireless communication mode. The vehicle information is information that can be used to diagnose a fault of the vehicle, which is acquired by the diagnostic device, and includes, but is not limited to: fault information, location information, attitude information, vehicle status information, mileage information, vehicle model information, vehicle configuration information, driver driving status information, etc. that can reflect vehicle faults, whether a vehicle has a potential fault, or information that can be used to judge whether a vehicle has a fault; alternatively, the vehicle information includes, but is not limited to: hardware configuration information of the vehicle, software information of the vehicle, operation and maintenance information of the vehicle, etc. can reflect a vehicle failure, whether the vehicle has a potential failure, or information that can be used to judge whether the vehicle has a failure. The vehicle diagnostic method includes the following steps.

Step S1, establishing a communication connection between a user terminal and a server cluster, where the server cluster includes a distribution server and a plurality of diagnostic servers.

In one embodiment, the user terminal may be a computer, a mobile phone, a tablet, or other networking device, and the user terminal has a function of communicating with the server. The user terminal can establish communication connection with the server cluster through communication modes such as 5G, 4G, 3G, 2G and the like, and the user terminal establishes communication connection relation with one or more of the distribution server and the plurality of diagnosis servers in the server cluster.

Step S2, a diagnosis request is sent to the distribution server.

In one embodiment, the user sends a diagnostic request to the distribution server via an application or web page. The diagnostic request includes a unique identification code of the vehicle and a time stamp of the request, and a character string consisting of the identification code and the time stamp is unique.

After the user logs in the cloud platform through the user terminal, the cloud platform can determine whether the user can carry out remote diagnosis on the vehicle according to the user authority. Or after the common user logs in the cloud platform through the user terminal, the common user can only check basic information, fault diagnosis results, historical fault information, historical fault diagnosis results or other information of the vehicle, but does not have the authority to remotely diagnose the vehicle through the cloud platform; after the authority is opened by the common user, the vehicle can be remotely diagnosed through the cloud platform.

It should be noted that the distribution server may use a nginnx configuration, and the distribution server may be the same as the diagnostic server, may be different from the diagnostic server, may be one server in the server cluster, or may exist independently of the server cluster. When the distribution server exists independently of the server cluster, the server cluster includes only a plurality of diagnostic servers. However, only the distribution server in the server cluster can receive the diagnosis request sent by the user terminal.

A plurality of diagnosis servers in the server cluster exist as nodes, and the distribution server can add or delete the nodes according to actual needs to adapt to the actual needs and save calculation power.

In step S3, one of the plurality of diagnostic servers is selected, and a diagnostic request is sent to the selected diagnostic server.

In one embodiment, the distribution server receives a diagnosis request transmitted from the user terminal, selects one diagnosis server from the plurality of diagnosis servers to execute a communication connection function between the user terminal, the server cluster and the vehicle, and transmits the diagnosis request to the selected diagnosis server after the distribution server selects the diagnosis server.

Referring to fig. 2, in step S3, a diagnosis server of the plurality of diagnosis servers is selected, and a diagnosis request is sent to the selected diagnosis server, as follows.

In step S32, the distribution server selects a diagnosis server of the plurality of diagnosis servers according to the load balancing policy, and sends the diagnosis request to the selected diagnosis server.

In one embodiment, the distribution server selects one diagnosis server from the plurality of diagnosis servers according to the load balancing strategy, and the distribution server sends the diagnosis request to the selected diagnosis server, and the diagnosis server processes the communication connection and the diagnosis operation among the server cluster, the vehicle and the user terminal.

In step S322, the distribution server numbers the plurality of diagnosis servers.

In one embodiment, for example, the distribution server numbers the plurality of diagnostic servers as 0, 1, 2, 3, 4, 5 ….

In step S324, a hash code (hash) value of a character string composed of the identification code and the timestamp in the diagnosis request is calculated.

Step S326, perform hash (hash) modulo on the hash code value, and map the modulo value to the number of the diagnostic server.

Step S328, determining whether the serial number of the diagnosis server is equal to the modulo value, and if so, the diagnosis server with the same serial number is responsible for processing the diagnosis request.

In this way, through steps S322 to S328, the distribution server selects one diagnostic server from the plurality of diagnostic servers to handle the diagnostic request, and responds to the high-concurrency diagnostic request of the user terminal in time.

In step S4, a diagnosis instruction is formed according to the diagnosis request and sent to the diagnosis device of the vehicle.

In one embodiment, the selected diagnostic server processes the diagnostic request, parses the diagnostic request into a command format that can be recognized by the vehicle, and sends the parsed diagnostic command to the diagnostic device of the vehicle.

In this embodiment, the server cluster further includes a transit server.

And step S5, acquiring vehicle information of the vehicle according to the diagnosis instruction, and sending the vehicle information to the selected diagnosis server, wherein the vehicle information is information which is acquired by the diagnosis device and can be used for diagnosing the fault of the vehicle.

In one embodiment, after receiving the diagnosis instruction, the diagnosis device on the vehicle analyzes the diagnosis instruction and executes the diagnosis instruction, obtains vehicle information such as vehicle model, vehicle configuration, fault code, mileage, vehicle position and the like, and sends the obtained vehicle information to the selected diagnosis server or transfer server. The vehicle position can be used for confirming the position of the vehicle, and maintenance personnel can conveniently go to maintain the vehicle.

Specifically, referring to fig. 5, in step S5, vehicle information of the vehicle is obtained according to the diagnosis instruction, and the vehicle information is sent to the selected diagnosis server, as follows.

And step S52, acquiring the vehicle information of the vehicle according to the diagnosis instruction, and sending the vehicle information to the transfer server.

In one embodiment, the diagnosis device acquires vehicle information of the vehicle according to the received diagnosis instruction and directly transmits the vehicle information to the transit server.

In step S54, the vehicle information is transmitted to the selected diagnosis server.

In one embodiment, the transit server sends the received vehicle information directly back to the selected diagnostic server.

And step S6, forming a diagnosis report according to the vehicle information and sending the diagnosis report to the user terminal.

In one embodiment, the selected diagnosis server firstly judges whether the data format of the vehicle information conforms to the correct data format according to the received vehicle information, if so, the selected diagnosis server analyzes the received data into a diagnosis report which can be identified by the user terminal, and sends the formed diagnosis report to the user terminal for the user terminal to check.

It is understood that other embodiments of step S5 can also be step S5': and acquiring vehicle information of the vehicle according to the diagnosis instruction, and sending the vehicle information to the distribution server.

That is, the distribution server may transmit the vehicle information to the diagnosis server responsible for processing the diagnosis request according to the load balancing policy, or the distribution server may transmit the vehicle information to the selected diagnosis server according to the load balancing policy.

After step S6', step S6: and forming a diagnosis report according to the vehicle information, and sending the diagnosis report to the user terminal.

With reference to fig. 1, after forming a diagnosis report according to the vehicle information and sending the diagnosis report to the user terminal in step S6, the vehicle diagnosis method further includes the following steps.

In step S7, a diagnosis result is formed according to the diagnosis report. The diagnostic results include solutions made to the diagnostic report and repair results.

In an embodiment, after the user terminal displays the diagnosis report, the user can perform fault analysis on the vehicle according to the content in the diagnosis report and obtain a solution, and further arrange a maintenance person to maintain the vehicle. Meanwhile, the solution and maintenance result corresponding to the diagnosis report are recorded into the cloud platform, that is, the user sends the solution and maintenance result corresponding to the diagnosis report to the diagnosis server sending the diagnosis report through the cloud platform through the user terminal, or the solution and maintenance result corresponding to the diagnosis report are forwarded to the diagnosis server sending the diagnosis report through the distribution server, and the diagnosis server further forms a diagnosis result according to the diagnosis report and the received solution and maintenance result, so that each diagnosis report has a corresponding diagnosis result. The diagnosis server sending the diagnosis report is the selected diagnosis server.

In step S8, the diagnosis report and the corresponding diagnosis result are stored to form a database. The user can check the diagnosis report and the diagnosis result existing in the database through the user terminal, so that the vehicle fault diagnosis and maintenance are facilitated. The database is stored in the memory in the form of codes, the memory can be a stand-alone memory, a memory in a distribution server or a memory in a plurality of diagnosis servers, and the codes in the memory can be called to enable the database to be used.

In one embodiment, the memory is a stand-alone memory, and does not occupy the resources of the allocation server and the diagnostic server. After the selected diagnosis server forms the diagnosis result, the selected diagnosis server sends the diagnosis report and the diagnosis result to the memory in a data packaging mode for storage so as to form the database. It should be noted that, a large amount of historical data is needed for forming the database, and when the data in the database reaches a certain order of magnitude, the data in the database can be subjected to big data analysis through a computer program, and potential relationships among data information such as vehicle models, vehicle configurations, fault codes, solutions, fault reasons, mileage and the like are mined, so that the value of the database can be better utilized. For example, the probability that a vehicle of type A fails B is higher through the big data analysis database, or the vehicle of type A is likely to fail C when the vehicle of type A fails B, so that safety early warning can be performed on the vehicle, measures can be taken in advance, and the efficiency of remote diagnosis and the accuracy of diagnosis are improved.

With continuing reference to FIG. 1, it is to be understood that step S6 may also be a step followed by step S5 when the data in the database reaches a certain level so that it can be used.

In step S62, a diagnostic report is formed based on the vehicle information.

In one embodiment, the selected diagnosis server directly receives the vehicle information transmitted by the diagnosis device or the relay server, and analyzes the received vehicle information to form a diagnosis report.

In step S64, the diagnosis report is correlated with the database to form an early warning report. The early warning report comprises the fault corresponding to the diagnosis report, the solution corresponding to the fault of the diagnosis report, maintenance suggestions and the like.

In one embodiment, the selected diagnosis server associates the formed diagnosis report with the database, performs comparison analysis on the diagnosis report and a large amount of historical data existing in the database, and forms an early warning report according to the result of the comparison analysis. Specifically, after the diagnostic report is formed, vehicle characteristics such as vehicle type, configuration, fault code, mileage and the like of the vehicle are extracted, and the same or similar diagnostic report, solution and maintenance suggestion are matched in the database through data analysis. For example, the diagnosis report a has a vehicle model feature a, a configuration feature a, a fault code feature a and a mileage feature a, and a diagnosis report B that is the same as or similar to the diagnosis report a having the vehicle model feature a, the configuration feature a, the fault code feature a and the mileage feature a is matched in the database, so that the diagnosis server further calls a diagnosis result B corresponding to the diagnosis report B, and forms an early warning report with the diagnosis report a, the diagnosis report B and the diagnosis result B. Wherein, the diagnosis report B and the diagnosis result B are used for providing a solution and a repair suggestion for a user.

And step S66, sending an early warning report to the user terminal.

In one embodiment, the selected diagnosis server forms an early warning report and then sends the early warning report to the user terminal for the user to view and refer.
