[0043] In which, the diagnostic terminal is connected to the remote diagnostic equipment operated by the maintenance technician, thereby receiving the diagnostic request sent by the remote diagnostic equipment including the remote diagnostic equipment identification. Based on the diagnostic request, the diagnostic terminal sends a data acquisition request to the first server, wherein the data acquisition request may include the identification of the remote diagnostic equipment and the address information of the diagnostic terminal, and the address information may be the longitude and latitude information based on the Global Positioning System (GPS).

[0044] Specifically, before receiving the acquisition request from the diagnostic terminal, the method also includes: receiving data information sent by the remote diagnostic device, the data information is obtained by determining the network delay of the relay server when the remote diagnostic device performs remote diagnosis, the data information includes the identification of the remote diagnostic device, the identification of the relay server, the reference network delay and the remote diagnosis time, and the remote diagnostic device is connected to the diagnostic terminal; and storing the data information in a database.

[0045] Among them, when the remote diagnosis device starts remote diagnosis, it will upload the calculated network delay data with each relay server to the background server, and the background server will save this data to the database. The specific data content may include: the identification of the remote diagnosis device, the identification of the relay server, the network delay, and the time to start remote diagnosis.

[0046] Among them, the identifier of remote diagnosis can be the device serial number, such as "JD00123456", "JS-78901234", etc., or the physical address of the device, the specific code of the device, etc.; the identifier of the transit server can be the specific code of the transit server, such as "ZS001", "TransServer_05", or a specific identifier generated based on certain characteristics of the transit server, etc.

[0047] Specifically, the reference network delay is determined according to the network delays between the remote diagnostic device and the on-board diagnostic device and the transfer server respectively, and the on-board diagnostic device is connected to the vehicle to be diagnosed.

[0048] Among them, the first network delay between the relay server and the remote diagnostic device is calculated, and the second network delay between the relay server and the on-board diagnostic device is calculated, and the reference network delay is obtained according to the average of the first network delay and the second network delay.

[0049] S220: In response to the data acquisition request, acquire a relay server list, wherein the relay server list includes identifiers and address information of a plurality of relay servers.

[0050] The backend server searches for the relay server in the database according to the serial number of the remote terminal according to the request of the diagnostic terminal. The address of the relay server may be the address of the city where the relay server is located.

[0051] S230, determining target data, where the target data is used to indicate a relationship between the diagnosis terminal and each of the plurality of relay servers.

[0052] Specifically, the data acquisition request includes the identification of the remote diagnostic device, the address information of the diagnostic terminal and the address information of the on-board diagnostic device, and the determination of the target data includes: determining whether there is network delay data between the remote diagnostic device and the relay server in the database based on the identification of the remote diagnostic device; in the case where the network delay data exists, determining the reference network delay corresponding to the remote diagnostic time closest to the current time interval as the target network delay; sorting the target network delays to obtain a network delay list; sending the relay server list and the target data to the diagnostic terminal includes: sending the relay server list and the network delay list to the diagnostic terminal.

[0053] Among them, after receiving the request, the background server searches the database for the network delay data most recently uploaded by the device according to the identifier of the remote diagnostic device, and sorts the network delay corresponding to each relay server from small to large, or from large to small. The specific sorting method is not limited. After sorting, a network delay list including the relay server identifier and the network delay corresponding to the relay server is obtained. The background server sends the relay server list and the network delay list to the diagnostic terminal. Based on the received data, the diagnostic terminal can select the relay server with the shortest network delay as the target relay server.

[0054] Specifically, in the absence of the network delay data, the distances between the remote diagnostic device and the on-board diagnostic device and the relay server are determined according to the address information of the diagnostic terminal, the on-board diagnostic device and the relay server respectively; the target distance is determined according to the distances between the remote diagnostic device and the on-board diagnostic device and the relay server respectively; the target distances are sorted to obtain a distance list; and sending the relay server list and the target data to the diagnostic terminal includes: sending the relay server list and the distance list to the diagnostic terminal.

[0055] Among them, if the network delay data of the device is not found in the database, the background server will calculate the first distance between the diagnostic terminal and the relay server, and the second distance between the relay server and the on-board diagnostic device according to the location of the diagnostic terminal and the on-board diagnostic device in the data acquisition request, and the location of the city where the relay server is located, calculate the average of the first distance and the second distance to obtain the target distance, sort the target distance corresponding to each relay server from small to large, and obtain a distance list including the relay server identifier and the target distance corresponding to the relay server. The background server sends the relay server list and the distance list to the diagnostic terminal. Based on the received data, the diagnostic terminal can select the relay server with the shortest target distance as the target relay server.

[0058] The target data includes a network delay list, that is, the network delay data about the remote diagnosis device can be found in the background server, and the target data includes a data list, that is, the network delay data about the remote diagnosis device cannot be found in the background server. When the diagnosis terminal receives the network delay list, it can select the transit server with the shortest network delay in the network delay list as the target transit server. When the diagnosis terminal receives the distance list, it can select the transit server with the shortest distance in the distance list as the target transit server.

[0059] It can be seen that in the embodiment of the present application, the determination of the relay server is achieved by processing the relationship between each relay server and the diagnostic terminal in multiple relay servers, which improves the speed of data transmission during remote diagnosis and enhances the user experience.

[0060] In one possible embodiment, when it is determined that there is network delay data between the remote diagnosis device and the relay server in the database based on the identification of the remote diagnosis device, the most recent remote diagnosis time and the current time are compared to determine whether the preset interval time is exceeded. If the time interval between the most recent network delay data and the current time is too long, the reference network delay list and the distance list can be combined to determine the target relay server. Alternatively, the network delay data in the database can be regularly updated and deleted.

[0061] It can be seen that in the embodiments of the present application, the speed of diagnostic data transmission can be improved.
