[0044] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0045] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0046] The main solutions of the embodiments of this application are:

[0047] Get vehicle diagnostic requests and wireless connection requests;

[0048] Based on a pre-generated dual network connection mechanism, according to the wireless connection request, a communication connection is established with a preset wireless network of the diagnostic device, wherein the dual network connection mechanism includes a configuration file connection mechanism and a batch file connection mechanism;

[0049] Based on the connected diagnostic equipment wireless network, according to the vehicle diagnostic request, the vehicle is diagnosed through the preset diagnostic equipment to generate a vehicle wireless diagnostic result.

[0050] In the prior art, WIFI-based vehicle diagnostic equipment connects to WIFI by setting an automatic connection mode or manually connecting each time. Both of these connection modes are implemented through the system. After each vehicle is diagnosed, it is necessary to reconnect to WIFI to diagnose the next vehicle. The network connection time is limited by automatic connection through the system or manual connection to WIFI for vehicle diagnosis, which leads to low efficiency of vehicle diagnosis. In addition, wireless diagnostic technology also faces problems such as network stability, frequent disconnection, and low data transmission efficiency. These problems not only affect the user experience, but also limit the further application and development of wireless diagnostic technology.

[0051] The present application provides a solution for quickly connecting to a wireless network of a diagnostic device through a dual network connection mechanism, wherein the dual network connection mechanism includes a configuration file connection mechanism and a batch file connection mechanism. The configuration file connection mechanism can automatically connect to the wireless network of the diagnostic device. When the network connection fails, the batch file connection mechanism is automatically switched to realize the connection to the designated wireless network of the diagnostic device. Thus, the designated wireless network can be quickly connected to realize efficient, real-time and safe vehicle diagnosis, thereby improving the diagnostic efficiency and user experience.

[0052] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a vehicle wireless diagnostic system, etc. The following takes the vehicle wireless diagnostic system as an example to illustrate this embodiment and the following embodiments.

[0053] Based on this, the embodiment of the present application provides a vehicle wireless diagnosis method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle wireless diagnostic method of the present application.

[0054] In this embodiment, the vehicle wireless diagnosis method includes steps S10 to S30:

[0055] Step S10, obtaining a vehicle diagnosis request and a wireless connection request;

[0056] It should be noted that a vehicle diagnostic request refers to an inspection request regarding the vehicle status, fault or performance issued by a user, diagnostic equipment or the vehicle itself, including requirements for inspection of specific faults or performance issues. A wireless connection request refers to a request to establish communication with a diagnostic equipment via wireless means.

[0057] In a feasible implementation, step S10 may include steps S101 to S102:

[0058] Step S101, establishing a connection with the diagnostic device through a preset on-board diagnostic interface;

[0059] Step S102 : receiving the vehicle diagnosis request sent by the diagnostic device through the connected on-board diagnostic interface, and generating the wireless connection request.

[0060] The vehicle wireless diagnostic system establishes a connection with the diagnostic device through a preset on-board diagnostic interface, then receives a vehicle diagnostic request sent by the diagnostic device through the connected on-board diagnostic interface and generates a wireless connection request.

[0061] It should be noted that the on-board diagnostic interface refers to a standardized interface inside the vehicle (such as OBD-II), which is used to exchange data with external devices. The vehicle diagnostic request is a request issued by the diagnostic device, which usually contains the fault code, sensor data and other information that you want to obtain. The wireless connection request refers to a request to establish wireless communication after completing the wired connection to facilitate the wireless transmission of subsequent data.

[0062] In this implementation, the preset configuration of the on-board diagnostic interface is used to ensure that the device can complete the connection in the shortest time, reducing the waiting time. Once the connection is successful, the vehicle and the diagnostic device can quickly and in real time exchange data, improving the accuracy and response speed of the diagnosis. The system can automatically generate wireless connection requests, which means that the user does not need manual intervention, thereby reducing the risk of human error. As a result, the efficiency and accuracy of vehicle diagnosis can be significantly improved, the user experience can be improved, and the problems of connection stability and operation complexity existing in traditional vehicle diagnosis can be effectively solved, providing a more intelligent and convenient solution for vehicle maintenance.

[0063] Step S20, based on the pre-generated dual network connection mechanism, according to the wireless connection request, establishing a communication connection with the preset diagnostic device wireless network, the dual network connection mechanism including a configuration file connection mechanism and a batch file connection mechanism;

[0064] The vehicle wireless diagnostic system establishes a communication connection with a preset diagnostic device wireless network based on a pre-generated dual network connection mechanism and according to a wireless connection request.

[0065] It should be noted that the dual network connection mechanism includes two connection methods: the configuration file connection mechanism refers to the use of preset parameters and configuration files for connection, and the batch file connection mechanism refers to processing connection requests in a batch manner. The combination of the two mechanisms can improve the success rate and efficiency of the connection.

[0066] Exemplarily, an implementation of step S20 is as follows:

[0067] 1) Prefer to use the configuration file connection mechanism:

[0068] Read network information from the preset configuration file;

[0069] Try to connect to the designated diagnostic equipment wireless network;

[0070] Check the connection status and enter the data exchange phase if successful.

[0071] 2) Switch to batch file connection mechanism (if necessary):

[0072] If the configuration file connection fails, the batch connection script is automatically called;

[0073] Batch scripts can contain multiple candidate networks and try to connect in sequence;

[0074] Supports multiple protocols and port settings to accommodate different types of diagnostic equipment.

[0075] In a feasible implementation, step S20 may include steps S201 to S203:

[0076] Step S201, based on the configuration file connection mechanism and according to the wireless connection request, a network connection instruction is generated through a preset wireless network scanning module and sent to the diagnostic device wireless network;

[0077] Step S202, generating a serial number reading instruction according to the wireless connection request and sending the instruction to the diagnostic device;

[0078] Step S203, when the serial number data sent by the diagnostic device is not received within the preset waiting time, based on the batch file connection mechanism and according to the wireless connection request, a communication connection is established with the wireless network of the diagnostic device.

[0079] The vehicle wireless diagnostic system is based on a configuration file connection mechanism. According to the wireless connection request, a network connection instruction is generated and sent to the diagnostic device wireless network through a preset wireless network scanning module. The instruction usually contains the name, type and authentication information of the network. The network connection instruction is transmitted to the diagnostic device via a wireless signal. Once the diagnostic device receives the instruction, it will try to establish a connection. Then the system constructs a serial number reading instruction based on the connection status to request the diagnostic device to return its serial number. The serial number is a unique identifier of the device, which helps to confirm the identity of the device and ensure the security of data interaction. The serial number reading instruction is then sent to the diagnostic device through the established wireless connection. Once the device receives the instruction, it will return its serial number information. When the serial number data sent by the diagnostic device is not received within the preset waiting time, it is determined that the network connection has failed. Based on the batch file connection mechanism, according to the wireless connection request, a communication connection is established with the diagnostic device wireless network again to ensure that the system can continue to communicate with the device and obtain the required data as soon as possible.

[0080] It should be noted that the wireless network scanning module is used to scan available wireless networks in order to find the target device. Its function is to identify the surrounding wireless signals and select the appropriate network for connection. The network connection instruction is an instruction from the vehicle wireless diagnostic system to instruct the diagnostic device to establish a connection. Its function is to start the connection process with the specified wireless network. The serial number reading instruction is an instruction for requesting the diagnostic device to return its serial number. Its function is to obtain the identity information of the device for subsequent communication and data processing. The waiting time is the maximum waiting time set by the system when trying to receive serial number data.

[0081] When the vehicle wireless diagnostic system receives the serial number data sent by the diagnostic device within the preset waiting time, it indicates that the vehicle wireless diagnostic system and the diagnostic device are successfully connected, and the system does not need to switch to the batch file connection mechanism.

[0082] The following is an example of the process of connecting to the wireless network of the diagnostic device based on the batch file connection mechanism:

[0083] 1. Get the wireless network information of the diagnostic device. For example, the Wi-Fi network name (SSID) provided by the diagnostic device is DiagnosisDeviceSSID, and the BSSID (MAC address) is 00:11:22:33:44:55.

[0084] 2. Create a batch file.

[0085] In Windows environment, you can use the following command to create a batch file (such as connect_diagnosis_device.bat) to achieve wireless connection.

[0086] 3. Run the batch file.

[0087] 1) The user double-clicks the connect_diagnosis_device.bat file and the batch program starts executing.

[0088] 2) The program will try to connect to the defined wireless network DiagnosisDeviceSSID.

[0089] 3) After the connection is successful, the program will display the current network connection status.

[0090] Among them, the following points should be noted when connecting to a wireless network based on the batch file connection mechanism:

[0091] 1) Make sure the target wireless network has been configured in advance and saved to the computer's network list.

[0092] 2) Modify the PASSWORD in the script as needed to ensure successful connection to the network.

[0093] 3) Other commands can be added to the batch file, such as starting diagnostic software or performing data synchronization.

[0094] In this embodiment, the wireless network scanning module can quickly identify available wireless networks, ensuring that the diagnostic device can quickly find and connect to the appropriate network, thereby improving connection efficiency. The serial number reading instruction can obtain the device's identity information in real time, which helps to confirm the validity and accuracy of the device and enhance the security of the system. The dual network connection mechanism provides redundancy measures. When the serial number data is not received in time, the system can automatically switch to the batch file connection mechanism to ensure that the connection can still be established under special circumstances. In this way, the efficiency, stability and security of wireless connections can be significantly improved, while solving the common connection delays and device verification problems in the traditional diagnostic process, providing users with a smoother and more reliable vehicle diagnostic experience.

[0095] Step S30 , based on the connected diagnostic device wireless network and according to the vehicle diagnostic request, diagnose the vehicle through a preset diagnostic device to generate a vehicle wireless diagnostic result.

[0096] Before performing diagnosis, the vehicle wireless diagnostic system ensures that the connection to the wireless network of the diagnostic equipment is stable and the data transmission is normal. Then the system obtains the valid vehicle diagnostic request from the previous steps, extracts the required fault code or diagnostic item, uses the connected diagnostic equipment, calls the corresponding diagnostic program or tool, and selects the appropriate diagnostic module to execute the diagnostic process according to the specific conditions of the vehicle (such as model, age, etc.) to generate the vehicle wireless diagnostic results.

[0097] It should be noted that the vehicle wireless diagnostic results refer to the vehicle status report obtained after analysis by diagnostic equipment, which usually includes fault codes, performance indicators and other information. These results help technicians or users understand the specific condition of the vehicle.

[0098] Exemplarily, a possible flow of the diagnostic process performed is as follows:

[0099] 1) Data collection: Obtain real-time data from various control units of the vehicle (such as engine, brake system, transmission system, etc.).

[0100] 2) Fault analysis: Analyze the collected data, compare it with preset standards and fault codes, and identify potential problems.

[0101] 3) Generate diagnostic report: Generate a detailed diagnostic report based on the analysis results, including: fault code, fault description, possible causes, and recommended repair measures.

[0102] This embodiment provides a vehicle wireless diagnosis method, which quickly connects to a diagnostic device wireless network through a dual network connection mechanism, wherein the dual network connection mechanism includes a configuration file connection mechanism and a batch file connection mechanism. The configuration file connection mechanism can automatically connect to the diagnostic device wireless network, and when the network connection fails, the batch file connection mechanism is automatically switched to achieve connection to the designated diagnostic device wireless network. Thus, the designated wireless network can be quickly connected, and efficient, real-time and safe vehicle diagnosis can be achieved, thereby improving diagnostic efficiency and user experience.

[0103] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 2 Before step S20, the vehicle wireless diagnostic method further includes steps S401 to S403:

[0104] Step S401, generating the configuration file connection mechanism based on the pre-generated configuration file;

[0105] Step S402, generating the batch file connection mechanism based on the pre-generated batch file;

[0106] Step S403: obtaining the dual network connection mechanism according to the configuration file connection mechanism and the batch file connection mechanism.

[0107] The vehicle wireless diagnostic system first reads a pre-generated configuration file, which usually contains the parameters required for connection, such as IP address, port number, connection protocol, etc., to ensure that the system obtains the correct connection information for subsequent connection operations, and then parses the content in the configuration file into available variables or objects and verifies them to facilitate subsequent program calls. According to the parsed and verified parameters, a configuration file connection mechanism is generated, and then a pre-generated batch file is read. The file contains a series of commands or scripts for connection to ensure that the system obtains all operation instructions required for connection and forms the basis for subsequent execution. The content in the batch file is parsed into an executable command list and verified, and a connection mechanism is constructed according to the verified command list. A batch file connection mechanism is generated, and finally the configuration file connection mechanism and the batch file connection mechanism are integrated to form an overall connection strategy to obtain a dual network connection mechanism to ensure that the system can take advantage of the advantages of both mechanisms at the same time to achieve a more reliable connection.

[0108] It should be noted that the configuration file contains the parameters required for the connection (such as IP address, port number, etc.) and is used to normalize and standardize the connection settings. The batch file is a set of predefined commands used to automatically execute connection tasks and improve efficiency.

[0109] In a feasible implementation manner, before step S401, steps S5011 to S5012 may also be included:

[0110] Step S5011, obtaining wireless network identifier data, identifier string data and wireless network password data;

[0111] Step S5012: Fill the wireless network identifier data, identifier string data and wireless network password data into a preset configuration file template to generate the configuration file.

[0112] The vehicle wireless diagnostic system obtains the wireless network identifier data, the identifier string data and the wireless network password data, and then fills the wireless network identifier data (SSID), the identifier string data and the wireless network password data into the corresponding positions in the preset configuration file template, and creates a final configuration file based on the filled data, which is usually saved in a specific format (such as JSON, XML or a specific configuration file format).

[0113] It should be noted that the wireless network identifier data (SSID) is the name of the wireless network, which is used to distinguish different networks. It is the basic information required to connect to the network; the identifier string data is the unique identification information of the user or device, which may be used to track or manage the connected device; the wireless network password data is the password required to protect the security of the wireless network. Only by entering the correct password can you connect to the network; the configuration file template is a predefined file format that contains the required fields to store network connection information. The template ensures that the generated file meets the system requirements; the configuration file contains specific wireless network connection information for the system to read and use.

[0114] For example, refer to Figure 3 , Figure 3 A schematic diagram of the contents of a configuration file provided in Example 2 of the present application.

[0115] The configuration file is in XML format and the file name is WLAN-XXXXXX.xml, where XXXXXXX is the WIFI SSID. It includes information such as the WIFI SSID, WIFI password, and SSID hexadecimal string.

[0116] In this embodiment, by automatically acquiring wireless network information and generating configuration files, the steps of manual input are reduced, and the risk of human error is reduced. This makes the configuration process more efficient and standardized. Whenever the network environment changes (such as changing the network or password), the system can obtain new wireless network information in real time and regenerate the configuration file, thereby ensuring that the device is always connected to the correct network. The generated configuration file is personalized according to the actual acquired data, and can adapt to different types of network environments, thereby enhancing the system's compatibility with a variety of network conditions. In this way, the automation and real-time update of wireless network configuration can be achieved, which significantly improves the flexibility and reliability of the system, while solving the complexity and security issues of manual configuration, and providing more effective technical support for wireless diagnostic methods.

[0117] In another feasible implementation manner, before step S402, steps S5021 to S5022 may also be included:

[0118] Step S5021, obtaining wireless network identifier data and wireless network name data;

[0119] Step S5022: Fill the wireless network identifier data and the wireless network name data into a preset batch processing file template to generate the batch processing file.

[0120] The vehicle wireless diagnostic system obtains the wireless network identifier data and the wireless network name data, and then replaces the placeholders (such as {SSID} and {NetworkName}) in the preset batch file template according to the wireless network identifier data and the wireless network name data. This process can be automated using programming languages ​​(such as Python, PowerShell, etc.) or text processing tools to generate batch files.

[0121] It should be noted that the wireless network identifier data (SSID), Service Set Identifier, indicates the name of the wireless network and is used to distinguish different networks; the wireless network name data is usually a description of the SSID or a more recognizable name, which may include information such as brand or location; a batch file template is a predefined file format used to store and execute a series of commands, usually for automated tasks; a batch file is a file containing a series of commands that can be run in a command line environment to achieve batch processing.

[0122] For example, refer to Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the first part of the contents of the batch file provided in Example 2 of the present application. Figure 5 A schematic diagram of the second part of the contents of the batch file provided in Example 2 of the present application.

[0123] The batch file format is bat, the file name is ConnectWifi.bat, and it includes information such as WIFI SSID and WIFI name.

[0124] In this implementation, by obtaining the wireless network identifier and name, it is possible to achieve a comprehensive control of the network environment, provide basic information for subsequent configuration and management, and enable network management personnel to have a clearer understanding of the network environment in which they are located. The automatically generated batch file can be used to quickly configure multiple devices or perform specific network operations, thereby improving the efficiency and consistency of network management. The use of preset batch file templates ensures the standardization of configurations between different devices or systems, and reduces errors caused by manual input. As a result, it is possible to quickly obtain and batch process wireless network information, improve the automation, standardization and efficiency of wireless network management, and at the same time, effectively solve technical problems such as information islands, cumbersome manual configuration, and inconsistent device management, providing strong support for network management.

[0125] For example, taking the on-board diagnostic interface as the on-board diagnostic system OBD and the vehicle wireless diagnostic system including the vehicle communication interface VCI as an example, a feasible implementation of the vehicle wireless diagnostic method described in this embodiment is as follows:

[0126] 1. Configure the configuration file and content for connecting to WIFI (WLAN-XXXXXXX.xml), see Figure 3 , where XXXXXXX is the WIFI SSID.

[0127] 2. Configure the batch file and content for connecting to WIFI (ConnectWifi.bat), see Figure 4 and Figure 5 .

[0128] 3. Connect the vehicle's OBD interface to the diagnostic device, which will start up and broadcast the WIFI signal.

[0129] 4. Based on the configuration file connection mechanism, VCI automatically searches for the WIFI signal of the diagnostic device and connects for communication.

[0130] 5. VCI issues a command to read the serial number of the diagnostic device (2103):

[0131] 1) If the diagnostic equipment responds positively, proceed to the next vehicle diagnostic operation;

[0132] 2) If the diagnostic device does not respond, VCI automatically switches to the second WIFI connection method based on the batch file connection mechanism;

[0133] 3) VCI connects to the specified WIFI through a program call batch process, and then performs the next step of vehicle diagnosis operation on the vehicle.

[0134] 6. After the vehicle diagnosis is completed, unplug the diagnostic equipment from the vehicle's OBD interface and replace it with the next vehicle for diagnosis.

[0135] 7. Follow steps 3-6 in order.

[0136] Compared with the existing methods, the vehicle wireless diagnosis method described in this embodiment uses a dual network connection mechanism to quickly connect to WIFI. First, the WIFI is automatically connected through the configuration file connection mechanism. When the VCI automatic connection mode fails, the configuration file connection mechanism can automatically switch the program loading command to connect to WIFI, configure the configuration file for connecting to WIFI, configure the batch file, and VCI calls the batch loading WIFI configuration file to implement the automatic call of the WIFI connection instruction, so as to quickly connect to the specified WIFI, which can realize efficient, real-time and safe vehicle diagnosis, thereby improving the diagnosis efficiency and user experience.

[0137] In this embodiment, the two connection mechanisms enable the system to not only adapt to a single network environment, but also flexibly select the optimal connection method according to different situations. This flexibility improves the availability of the system. Through the dual network connection mechanism, even if one of the connection methods fails, the system can still restore the connection through another method to ensure that the diagnostic process is not interrupted. After integrating these two connection mechanisms, the device can automatically determine and switch the connection method without manual intervention, reducing the possibility of human error and improving work efficiency. As a result, a vehicle wireless diagnostic method with both flexibility and stability is provided, which solves the limitations of traditional methods in a changing network environment and significantly improves the reliability, security and user experience of the system.

[0138] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the vehicle wireless diagnostic method of the present application. More simple transformations based on this technical concept are all within the protection scope of the present application.

[0139] This application also provides a vehicle wireless diagnostic device, please refer to Figure 6 , the vehicle wireless diagnostic device comprises:

[0140] A request acquisition module 10, used to acquire a vehicle diagnosis request and a wireless connection request;

[0141] A wireless connection module 20, configured to establish a communication connection with a preset wireless network of a diagnostic device according to the wireless connection request based on a pre-generated dual network connection mechanism, wherein the dual network connection mechanism includes a configuration file connection mechanism and a batch file connection mechanism;

[0142] The vehicle diagnosis module 30 is used to diagnose the vehicle through a preset diagnostic device based on the connected diagnostic device wireless network and according to the vehicle diagnosis request, and generate a vehicle wireless diagnosis result.

[0143] Optionally, the wireless connection module 20 is further used for:
