Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.
At present, the prior art causes a diagnosis process to be more complicated and inconvenient for a user, thereby reducing the efficiency of vehicle diagnosis. Therefore, the vehicle diagnosis scheme can avoid frequent tool switching in the diagnosis process, and provides convenience for users to use, so that the diagnosis efficiency is improved.
Referring to fig. 1, an embodiment of the present application discloses a vehicle diagnostic method applied to a diagnostic apparatus, including:
s101, receiving a diagnosis instruction input by a user;
s102, judging whether the diagnosis software is idle or not; if yes, executing S103; if not, executing S105;
in one embodiment, determining whether the diagnostic software is idle comprises: it is determined whether a flag bit in the first registry is a first target value indicating that the diagnostic software is idle. Specifically, in order to distinguish whether the diagnostic software is idle, a first registry may be provided in which the flag bit is assigned two different values, one value (i.e., a first target value) indicating that the diagnostic software is idle and the other value (i.e., a second target value) indicating that the diagnostic software is running. In the diagnosis process, a second target value can be assigned to the zone bit after the diagnosis software is started; if the diagnosis process is finished, a first target value is assigned to the flag bit. In the initial state, the default value of the flag bit in the first registry is set as a first target value indicating that the diagnostic software is idle.
It should be noted that the remote diagnosis and the local diagnosis may be set to be executed in parallel, or alternatively.
If the remote diagnosis and the local diagnosis are set to be executed in parallel, the remote diagnosis corresponds to a first registry, and the first registry is used for identifying whether the diagnosis software corresponding to the remote diagnosis is idle or running. The local diagnostics correspond to another first registry for identifying whether another piece of diagnostic software corresponding to the local diagnostics is idle or running. The remote diagnosis and the local diagnosis are set to be executed in parallel, the remote diagnosis and the local diagnosis correspond to different first registration tables, different diagnosis software and different dynamic libraries, and the dynamic libraries need to be called after the diagnosis software is started. If the setting is carried out, no matter the remote diagnosis process or the local diagnosis process is executed, after the diagnosis software is started, a second target value is assigned to the zone bit in the first registry; if the diagnosis process is finished, a first target value is assigned to the zone bit in the first registry. In the initial state, a default value is assigned to the zone bit in the first registry, and the default value is a first target value.
If the remote diagnosis and the local diagnosis are set to be selected for execution, the remote diagnosis and the local diagnosis correspond to the same first registry, the same diagnosis software and the same dynamic library. At this point, the first registry is used to identify whether the diagnostic software is idle or running. If so, after the diagnostic software is started, assigning a second target value to the zone bit in the first registry; if the diagnosis process is finished, a first target value is assigned to the zone bit in the first registry. In the initial state, a default value is assigned to the zone bit in the first registry, and the default value is a first target value.
S103, calling a function corresponding to the diagnosis instruction to trigger a diagnosis event;
the diagnosis event is a remote diagnosis event or a local diagnosis event. Specifically, the operable buttons for entering remote diagnosis and local diagnosis can be presented on the top page of the target diagnosis tool, as shown in fig. 2. When the user clicks the operable button, the target diagnosis tool calls a function corresponding to the operable button to trigger a corresponding diagnosis event. The operable buttons are pre-bound to their corresponding functions.
S104, carrying out fault diagnosis on the vehicle according to the diagnosis process corresponding to the diagnosis event;
and S105, generating and displaying the prompt information of diagnosis.
If the diagnostic event is a remote diagnostic event, the vehicle is diagnosed for a fault according to a remote diagnostic flow corresponding to the remote diagnostic event. And if the diagnosis event is a local diagnosis event, performing fault diagnosis on the vehicle according to a local diagnosis process corresponding to the local diagnosis event.
In the remote diagnosis, please refer to fig. 3 for the communication connection between the diagnostic device and the vehicle. In fig. 3, the diagnostic device is connected to the vehicle via a VCI box, i.e. a communication connector; the VCI box is connected to the OBD diagnostic seat of the vehicle (the interface on the vehicle for diagnosing faults). The diagnostic device is a PC (Personal Computer) and dll (dynamic Link library) is a dynamic library of diagnostic software calls. On one hand, the PC can directly perform data interaction with the VCI box through the Internet, and can also perform data interaction with the VCI box through the server, and any one of the PC and the VCI box can be selected.
In the local diagnosis, the communication connection between the diagnostic device and the vehicle is shown in fig. 4. In fig. 4, the diagnostic device is connected to the vehicle via a VCI box, i.e. a communication connector; the VCI box is connected to the OBD diagnostic seat of the vehicle (the interface on the vehicle for diagnosing faults). The diagnostic device is a PC (Personal Computer) and dll (dynamic Link library) is a dynamic library of diagnostic software calls. The PC is connected with the VCI box in a mode of a USB data line and the like.
It should be noted that the remote diagnosis and the local diagnosis can adopt diagnosis protocols such as J2534, D-PDU and the like to diagnose the fault of the vehicle.
In the prior art, since the IP address used in the local diagnostic process is the IP address of the communication connector, and the IP address used in the local diagnostic process is the IP address of the diagnostic device, the diagnostic devices independent of each other need to use two different dynamic libraries to store the IP address used in the diagnostic process. And two different dynamic libraries are needed in the diagnosis process, so that the flexibility and the universality of the diagnosis process are reduced.
If the remote diagnosis and the local diagnosis are integrated in the same diagnosis device and are set to be alternatively executed, the same dynamic library and the same diagnosis software can be used for the remote diagnosis and the local diagnosis. The target diagnosis tool, the dynamic library and the diagnosis software are all application programs installed in the diagnosis equipment, and the target diagnosis tool is integrated with two diagnosis processes of remote diagnosis and local diagnosis.
In one specific embodiment, the process of diagnosing the fault of the vehicle according to the diagnostic process corresponding to the remote diagnostic event includes: detecting whether the diagnostic equipment is accessed to the Internet; if so, writing the IP address of the diagnostic equipment into a second registry, and establishing network connection between the diagnostic equipment and the communication connector; the communication connector is in communication connection with the vehicle; if the diagnosis software is started, establishing network connection between the dynamic library and the target diagnosis tool; and updating the flag bit to a second target value indicating that the diagnostic software is running, and performing fault diagnosis on the vehicle by using the diagnostic software.
Specifically, establishing a network connection between the dynamic library and the target diagnostic tool includes: the dynamic library reads the IP address of the device from the second registry and establishes a network connection with the target diagnostic tool using the IP address. Of course, the dynamic library and the target diagnostic tool may establish a communication connection in a memory sharing manner. The IP address of the device may be a local loopback address of the device, or an IP address of a network card in the device.
And if the diagnosis equipment does not access the Internet, generating and displaying a prompt message without network connection.
Wherein, if the diagnostic software is started, before establishing the network connection between the dynamic library and the target diagnostic tool, the method further comprises: judging whether the diagnostic equipment and the communication connector establish network connection or not; if so, generating and displaying a prompt message for starting the diagnostic software so that a user can start the diagnostic software; if not, executing the step of generating and displaying the prompt message without network connection.
In a specific embodiment, the process of diagnosing the fault of the vehicle according to the diagnostic process corresponding to the local diagnostic event includes: inquiring the IP address of the communication connector, and writing the IP address into a second registry; the communication connector is in communication connection with the vehicle; if the diagnosis software is started, establishing network connection between the dynamic library and the communication connector; and updating the flag bit to a second target value indicating that the diagnostic software is running, and performing fault diagnosis on the vehicle by using the diagnostic software.
Specifically, the establishing of the network connection between the dynamic library and the communication connector includes: the dynamic library reads the IP address of the communication connector from the second registry and establishes a network connection with the communication connector according to the IP address.
It should be noted that, the remote diagnosis and the local diagnosis are integrated into the same diagnosis device, and the remote diagnosis and the local diagnosis are set to be executed in parallel, so that the remote diagnosis corresponds to a second registry, and the second registry is used for storing the IP address of the PC. The local diagnostics correspond to another second registry for storing the IP address of the VCI box. That is, the remote diagnosis and the local diagnosis are set to be executed in parallel, and the remote diagnosis and the local diagnosis correspond to different second registries. In the initial state, the IP address in the second registry is a default IP address, and the default IP address is as follows: 0.0.0.0.
it can be seen that, the diagnostic device provided by the embodiment receives the diagnostic instruction input by the user; firstly, judging whether the diagnostic software is idle; if the diagnostic software is idle, indicating that a new diagnostic process can be executed, calling a function corresponding to the diagnostic instruction to trigger a corresponding diagnostic event, wherein the diagnostic event is a remote diagnostic event or a local diagnostic event; and further carrying out fault diagnosis on the vehicle according to the diagnosis process corresponding to the diagnosis event. Therefore, the remote diagnosis and the local diagnosis are integrated in the same diagnosis device, frequent tool switching in the diagnosis process can be avoided, convenience is provided for users, and the diagnosis efficiency is improved.
The specific implementation process of integrating the remote diagnosis and the local diagnosis into the same diagnosis device and setting the alternative execution of the remote diagnosis and the local diagnosis can be referred to fig. 5. Remote diagnostics and local diagnostics are integrated into the target diagnostic tool.
In FIG. 5, when a user turns on a target diagnostic tool in a diagnostic device (PC), then the target diagnostic tool reads the current assignment of the flag bit in the first registry; if the current value is 1 (namely the second target value), the diagnostic software is indicated to be running, and a user is prompted that a diagnostic mode cannot be selected currently; if the current value is 0 (i.e., the first target value), it indicates that the diagnostic software is idle, and the user is prompted that a diagnostic mode can be currently selected.
The storage path of the first registry in the PC may be: the computer \ HKEY _ CURRENT _ USER \ Software \ SmartBoxTool 3.0\ IsLoad, which is a flag bit, and judges whether the diagnosis is in progress or not according to the value of the IsLoad.
The home interface of the target diagnosis tool may present two options (as shown in fig. 2), one is local diagnosis and one is remote diagnosis, and the two options can be selected alternatively. These two modes cannot be selected simultaneously. When the user clicks any option, the target diagnosis tool judges whether the diagnosis is in progress according to the value of the IsLoad; if the IsLoad is 0, prompting the user to select a diagnosis mode; if IsLoad is 1, the user is prompted that the diagnosis is in progress, please later.
If the user clicks the local diagnosis and IsLoad is 0, then the local diagnosis process is entered. See fig. 5 for local diagnostic flow. As shown in fig. 5, if the user clicks the local diagnosis, the target diagnosis tool creates a broadcast service to query the IP address of the VCI box, and then stores the queried IP address into a second registry, where the storage path of the second registry in the PC may be: computer \ HKEY _ CURRENT _ USER \ Software \ SmartBoxTool 3.0\ Addr. And then the target diagnosis tool prompts a user to open the diagnosis software, if the diagnosis software is started, the dynamic library is called, at the moment, the dynamic library reads the IP address of the VCI box from the second registry, and the communication connection between the dynamic library and the VCI box is established. This communication connection may be a TCP network link and the port of the VCI box is 22488. Before the diagnostic software runs, IsLoad is modified to 1, after which local diagnostics are started. And if the local diagnosis is finished, modifying IsLoad to 0.
If the user clicks remote diagnosis and Isload is 0, then the remote diagnosis process is entered. See fig. 5 for a remote diagnosis process. As shown in fig. 5, if the user clicks the remote diagnosis, the target diagnosis tool detects whether the PC is connected to the internet; if not, prompting to check the network connection, and timing to wait; if the waiting time is overtime, the current diagnosis process is ended. The waiting time of the timing can be flexibly adjusted, such as 3 minutes. If the PC has access to the Internet, the IP address of the PC (e.g. 127.0.0.1 of the local loopback address of the PC) is stored in a second registry, and the storage path of the second registry in the PC can be: computer \ HKEY _ CURRENT _ USER \ Software \ SmartBoxTool 3.0\ Addr. And then, directly connecting the target diagnosis tool and the VCI box through a transfer server or P2P to establish network connection, and if the network connection is ready, prompting that the network connection is ready by the target diagnosis tool and opening diagnosis software. If the diagnostic software is started, the IP address of the PC is read from the second registry, and a TCP network link of the dynamic library and the target diagnostic tool is established. Before the diagnostic software runs, IsLoad is modified to 1, after which remote diagnostics are started. And if the remote diagnosis is finished, modifying IsLoad to 0. If the network connection is not ready, the current diagnostic process is ended.
Therefore, the remote diagnosis and the local diagnosis are integrated in the same diagnosis device, and the remote diagnosis and the local diagnosis are alternatively executed, so that the multiplexing of the dynamic library and the diagnosis software is realized.
