105. Judging whether the second data meets qualified display conditions or not;
specifically, the second data sent by the server may be two types, one type is the second data sent after the server is judged to be qualified, the other type is the second data sent after the server is judged to be unqualified, the second data has prompt information for judging to be qualified and unqualified, and the diagnosis software judges whether the second data meets the qualified display condition according to the prompt information so as to correspondingly display the second data.
106. Performing first display, wherein the first display is a processing result after the server inquires the second data;
specifically, the first display is performed to indicate that the diagnosis process conforms to the validity defined by the diagnosis software, that is, through the judgment process between the diagnosis software and the server, the processing result may include the fault code that is successfully queried, and the related information such as the explanation of the fault code.
107. And performing a second display, wherein the second display represents diagnosis failure and is provided with failure prompt information.
Specifically, the second display is performed, although the current diagnosis process is failed, the diagnosis failure here does not mean that the server does not inquire or diagnose the corresponding conclusion, but means that the diagnosis process does not pass through the judgment process of the diagnosis software and the server to represent the diagnosis failure, and the failure prompt message carried by the diagnosis failure prompt message can indicate the reason of the diagnosis failure.
In this embodiment, first data of a vehicle to be detected is read, whether the first data meets a sending condition is judged, if the first data meets the sending condition, the first data is sent to a server, so that the server queries second data according to the first data, receives the second data sent by the server, and judges whether the second data meets a qualified display condition, if the second data meets the qualified display condition, a first display is performed, and the first display is a processing result of the server after querying the second data. And judging whether the account is successfully logged in and whether the diagnosed result is displayed according to the second data, so that the possibility of leakage of the vehicle fault code and the related data is reduced.

To explain the server-side processing, in this embodiment, one embodiment of a method for vehicle diagnosis includes:
301. receiving first data sent by diagnostic software;
specifically, the server receives first data sent by the diagnosis software, and the first data can include vehicle fault codes read by the diagnosis software and identification information of the vehicle-mounted diagnosis system.
302. Judging whether the query state of the first data is legal or not;
specifically, whether the first data meet the qualified display condition is judged, and the judgment is mainly realized by judging whether the current diagnosis process meets a legal mode preset by a system in order to prevent the vehicle-mounted fault code information from being maliciously inquired.
303. If the query state of the first data is legal, generating second data according to the first data, wherein the second data comprises fault code information corresponding to the first data and prompt information that the query state is legal;
specifically, if the first data meets the qualified display condition, the second data includes fault code information corresponding to the first data, if the first data does not meet the qualified display condition, the second data does not include the fault code information corresponding to the first data but includes prompt information that does not meet the qualified display condition, it can be understood that the first data may include a vehicle fault code read by the diagnostic software and identification information of the on-board diagnostic system, the second data may include generation-related information corresponding to a determination result of the server on the first data, if the determination is passed, the second data includes fault code-related information generated corresponding to the vehicle fault code in the first data, if the determination is not passed, the second data includes a reason that the second data fails to correspond to the first data but does not include fault code-related information generated corresponding to the vehicle fault code in the first data, the process of generating the fault code related information generated corresponding to the vehicle fault code in the first data may be that a text is preset in a service period, the text has a corresponding relationship between the vehicle fault code and the vehicle-mounted diagnostic system and the fault code information, the server obtains the desired fault code information according to the corresponding relationship between the vehicle fault code in the first data and the vehicle-mounted diagnostic system, and the generated second data includes identification information indicating whether the process is passed or not, the identification information is used for prompting the diagnostic software, and whether the diagnostic process is legal or not is determined, so that the corresponding display is performed.
304. If the query state of the first data is illegal, generating second data according to the first data, wherein the second data contains prompt information that the query state is illegal, but does not contain fault code information corresponding to the first data;
specifically, if the query state of the first data is illegal, the second data is generated according to the illegal reason of the first data and is sent to the diagnostic software, when the second data is sent to the diagnostic software, the diagnostic software can judge that the diagnosis is failed according to prompt information that the query state contained in the second data is illegal, and give out related failure prompt, wherein the failure prompt has failure reasons, namely the prompt information about the illegal query state, but specifically, the display means on the diagnostic software can be a string of characters stored in a product specification, so that a user can obtain the failure reasons according to the review specification, and can also directly display the failure reasons.
305. Sending the second data to diagnostic software.
Specifically, the second data is generated and then sent to the diagnostic software, the diagnostic software correspondingly indicates whether the identification information in the second data passes the judgment process or not, if the identification information indicates that the judgment process passes, the diagnostic software extracts the fault code information in the second data for display, and if the identification information indicates that the judgment process fails, the diagnostic software extracts the corresponding information in the second data indicating the reason for the failure and displays the corresponding information.
In this embodiment, first data sent by diagnostic software is received, whether the query state of the first data is legal is determined, if the query state of the first data is legal, second data is generated according to the first data, and if the query state of the first data is illegal, the second data includes prompt information corresponding to the fault code information of the first data and prompt information corresponding to the query state, and if the query state of the first data is illegal, second data is generated according to the first data, and the second data includes prompt information not corresponding to the query state but does not include fault code information corresponding to the first data, and is sent to the diagnostic software, so that the diagnostic software performs corresponding display according to the prompt information in the second data. The server side judges the legality of the first data so as to correspondingly generate the second data to return to the diagnostic software for corresponding display, so that the possibility that the data stored in the diagnostic software is maliciously cracked can be avoided, and the possibility of data loss is reduced.
In this embodiment, based on the embodiment in fig. 3, a process of determining whether the first data meets the qualified display condition is further explained, specifically referring to fig. 4, another embodiment of the method for vehicle diagnosis includes:
40. it is determined whether the second data meets the qualifying display condition.
Specifically, whether login verification information of the first data is the same as a preset value or not is judged;
if the login verification information of the first data is the same as a preset value, judging whether the connector serial number of the first data is consistent with the connector serial number stored in the server or not;
if the login verification information of the first data is different from the preset value, judging that the first data does not meet the qualified display condition;
if the connector serial number of the first data is consistent with the connector serial number stored in the server, judging whether the current query state conforms to an illegal policy, wherein the illegal policy is a preset parameter range of illegal query;
if the connector serial number of the first data is inconsistent with the connector serial number stored in the server, judging that the first data does not meet qualified display conditions;
if the first data do not meet the illegal policy, judging that the first data meet qualified display conditions;
if the violation policy is met, judging that the first data does not meet qualified display conditions;
specifically, the above process may be understood as determining whether the first data meets the qualified display condition, and mainly determining three aspects, that is, whether the login authentication information, the connector serial number and the illegal policy are met, where the login authentication information may be embodied in a token mode, that is, in the diagnosis process, the server issues a data to the login account and requests the login account to be input at a fixed location, and if the input data is consistent with the issued data, the login authentication information is determined;
the process of judging the serial number of the joint, the joint refers to the joint that the diagnostic equipment is connected with the vehicle-mounted diagnostic system, each joint has a fixed and unique serial number, and is bound with the account and stored in the server, the process is to prevent the behavior that different accounts use the same joint, only when the diagnostic software detects that the currently used joint serial number is consistent with the serial number of the stored server, the judgment of the joint serial number is passed;
in the process of determining the illegal policy, it can be understood that the server determines some diagnostic states violating the ordinary diagnostic requirement in advance, and for example, in the case of corresponding to the same account and the same connector serial number, the following specific examples are provided in this embodiment:
a) reading a maximum of 20 fault codes at a time;
b) if the same system ID request fault code in any 3 minutes and the last time have more than 9 different fault codes, 10 or more fault codes are continuously available twice, entering a blacklist;
c) if 10 times of requests are accumulated to generate different fault codes within 60 minutes, entering a blacklist; for example, the cases of the first request P0109, the second requests P0103 and P0104, the third request P0105, the fourth requests P0110 and P0102, and the fifth request P0207 are also classified as illegal;
d) reading 50 different fault codes at most in one day, and entering a blacklist when the number of the different fault codes read within two days reaches 80;
the above example is not fixed, in a specific implementation process of the scheme, different definitions are performed on the illegal policy, if the illegal policy is in accordance with the scope of the illegal policy, the diagnosis state is not determined, and if the illegal policy is not in the scope, the diagnosis state is determined, it is noted that although the determination of whether the login verification information, the connector serial number, and the diagnosis state conform to the illegal policy in this embodiment is embodied in a flow form, the sequence of the three determination processes is not specified, it can be understood that no matter a failure of one determination process, the first data is represented as being illegal, so that corresponding second data is generated, and only when all three determination processes are successful, the second data including the fault code information is generated.
