[0021] The vehicle computer diagnosis method based on multi-channel communication is applied to Figure 5 In the computer device 500.

[0022] Figure 1 : is a flow chart of a vehicle computer diagnosis method based on multi-channel communication provided by an embodiment of the present application, the method comprising the following steps S110-S170:

[0023] S110, obtaining networking information of the vehicle diagnostic instrument, and determining whether each diagnostic module in the vehicle diagnostic instrument is in a network available state according to the networking information;

[0024] S120, selecting a diagnostic module in a network available state to add to a waiting-to-start sequence, and the vehicle diagnostic instrument arranges a waiting-to-diagnose agenda in the waiting-to-start sequence;

[0025] S130, obtaining vehicle computer diagnostic information of each diagnostic module, and determining whether the vehicle computer diagnostic instrument is in a diagnostic function operation state according to the vehicle computer diagnostic information;

[0026] S140, selecting a diagnostic module in a diagnostic function running state to add to a diagnostic scheduling sequence, and arranging a diagnostic agenda for the diagnostic module in the diagnostic scheduling sequence;

[0027] S150, respectively arranging the priorities of the diagnostic modules in the to-be-started sequence and the diagnostic modules in the diagnostic scheduling sequence to obtain a first priority sequence and a second priority sequence;

[0028] S160, matching the diagnostic modules in the first priority sequence with the diagnostic modules in the second priority sequence to generate vehicle computer diagnostic result information;

[0029] S170 . Send a vehicle computer diagnosis and repair instruction to a vehicle computer that matches the vehicle computer diagnostic instrument according to the vehicle computer diagnosis result information.

[0030] In a more specific implementation process, the vehicle diagnostic system is started, the vehicle diagnostic instrument establishes a connection with the server through the first channel, and establishes a connection with the diagnostic box through the second channel, and the vehicle diagnostic instrument obtains its own networking information, including IP address, network status, etc. The network availability status of each diagnostic module in the vehicle diagnostic instrument is determined according to the networking information. The diagnostic module in the network availability status is added to the sequence to be started. In the sequence to be started, the vehicle diagnostic instrument arranges the diagnostic modules for the agenda to be diagnosed. The vehicle diagnostic instrument obtains vehicle diagnostic information from the diagnostic module. According to the diagnostic information, it is determined whether the vehicle diagnostic instrument is in the diagnostic function running state. The diagnostic module in the diagnostic function running state is added to the diagnostic scheduling sequence. The diagnostic agenda is arranged for the diagnostic modules in the diagnostic scheduling sequence. The diagnostic modules in the startup sequence and the diagnostic scheduling sequence are prioritized to obtain the first priority sequence and the second priority sequence respectively. The diagnostic module in the first priority sequence is matched with the diagnostic module in the second priority sequence to generate vehicle diagnostic result information. According to the diagnostic result information, the vehicle diagnostic instrument sends a diagnostic repair instruction to the vehicle to be tested. By configuring two wireless network communication channels, the stability and reliability of communication are improved, and the problem of diagnostic interruption caused by a single channel failure is avoided. Through the priority arrangement and matching process, the efficient execution of key diagnostic tasks is ensured, and the diagnostic efficiency is improved. Real-time acquisition of diagnostic information and rapid response ensure the accuracy and real-time nature of the diagnostic results. The dual-channel communication mechanism ensures that when a problem occurs in one channel, the other channel can continue to work, thereby not affecting the continuity of the vehicle computer diagnosis. Priority sorting ensures that important diagnostic tasks are executed first, speeds up the diagnostic process and improves the overall diagnostic efficiency. The system can quickly generate repair instructions based on the diagnostic results, repair the vehicle computer in a timely manner, and reduce the downtime caused by the fault. This method supports the access and arrangement of multiple diagnostic modules, has good scalability and flexibility, and is suitable for different types of vehicle computer diagnostic needs.

[0031] By using two independent WIFI channels, namely WIFI1 and WIFI2, the problem of coexistence of wireless networking and wireless diagnosis is effectively solved. WIFI1 (2.4GHz / 5GHz) is used for wireless networking communication between the vehicle diagnostic instrument and the external network (such as a server). The 2.4GHz band provides better penetration, while the 5GHz band provides higher transmission rate and stability. WIFI2 (2.4GHz / 5GHz) is specifically used for wireless diagnostic communication between the vehicle diagnostic instrument and the diagnostic box. The 5GHz band is selected for faster transmission speed and better anti-interference ability. Wireless networking (WIFI1) The vehicle diagnostic instrument connects to the Internet through WIFI1 for remote data synchronization, software updates and online support. Wireless diagnosis (WIFI2) The vehicle diagnostic instrument establishes a connection with the diagnostic box through WIFI2 for real-time vehicle diagnostic data exchange. Through two independent WIFI channels, WIFI networking and WIFI wireless diagnosis can be carried out simultaneously without interfering with each other. The 5GHz band provides a higher data transmission rate, which is particularly important for transmitting large amounts of diagnostic data. Compared with the 2.4GHz band, the 5GHz band is less susceptible to interference from other electronic devices, ensuring the accuracy of diagnostic data. Although the transmission distance and penetration ability of the 5GHz band are not as good as those of the 2.4GHz band, it is still sufficient for use in most vehicle diagnostic scenarios and provides a better transmission rate. Due to the increased transmission speed and reduced interference, the diagnostic process is faster, thereby improving the efficiency of car repair. Compatibility is reflected in the support of 2.4GHz and 5GHz dual-band communication, so that the vehicle diagnostic instrument can be flexibly used in different network environments. Through this dual-band, dual-channel wireless communication solution, the vehicle diagnostic system can not only achieve efficient data transmission, but also ensure the stability and reliability of the diagnostic process, thereby providing a better service experience in the field of automobile maintenance and service. The first channel (WIFI1) function is used for wireless networking communication between the vehicle diagnostic instrument and the server. The communication content includes but is not limited to remote data synchronization, software updates, online technical support, etc. The frequency band can be 2.4GHz or 5GHz, depending on the network configuration and requirements. The 5GHz band is usually used in scenarios that require higher transmission rates. The second channel (WIFI2) function is specifically used for wireless diagnostic communication between the vehicle diagnostic instrument and the diagnostic box. The communication content includes the exchange of real-time vehicle diagnostic data, fault code reading, real-time monitoring of vehicle status, etc. The frequency band is preferably 5GHz because it provides faster transmission speed and better anti-interference ability, which is essential to ensure the accuracy and real-time nature of diagnostic data. First channel (WIFI1): Network communication between the vehicle diagnostic instrument and the server. Second channel (WIFI2): Wireless diagnostic communication between the vehicle diagnostic instrument and the diagnostic box. Ensure that the network communication and diagnostic communication are separated to avoid mutual interference. Take advantage of the superior performance of the 5GHz frequency band to improve diagnostic speed and efficiency.The dual-channel design increases the redundancy of the system. Even if one channel fails, the other channel can still keep the system running. This design makes the vehicle computer diagnosis system more efficient and stable, and can adapt to different working environments and diagnosis needs.

[0032] In summary, by configuring two independent wireless communication channels (the first channel and the second channel), the system has communication redundancy, which significantly improves the communication stability and reliability during the diagnosis process. By prioritizing the diagnostic modules to be started, it is ensured that key diagnostic tasks can be executed first, thereby improving the diagnostic efficiency. The diagnostic modules in different priority sequences are matched to generate the vehicle computer diagnostic result information in real time, which speeds up the diagnostic process and improves the accuracy of the diagnosis. The system can send repair instructions remotely according to the diagnostic result information, realize the remote diagnosis and repair function, reduce the need for on-site maintenance, and improve service efficiency. Using wireless network communication, the vehicle computer diagnostic instrument can efficiently synchronize data and update software with the server, ensuring the latest status and performance of the diagnostic system. By using the 5GHz frequency band for diagnostic communication, the system has better anti-interference ability and is suitable for complex electromagnetic environments. The dual-channel design enables the system to flexibly adjust the communication strategy according to different diagnostic needs and network conditions, enhancing the adaptability of the system. In summary, the core effect of this technology is to improve the stability, efficiency, real-time and remote service capabilities of vehicle computer diagnosis, while enhancing the flexibility and anti-interference ability of the system.

[0033] In a more specific embodiment, executing method S110 further specifically includes executing steps S111-S112:

[0034] S111, sensing available signals from the vehicle diagnostic instrument to obtain networking information;

[0035] S112: Determine whether the networking information is a preset status value to determine whether the vehicle diagnostic instrument is in a network available state.

[0036] Specifically, in a more specific embodiment, the execution process of method S110 can be refined into the following steps S111-S112 to ensure the effective operation of the vehicle diagnostic instrument in the network environment. The vehicle diagnostic instrument is sensed for available signals to obtain networking information. After the vehicle diagnostic instrument is started, its built-in wireless signal sensing module starts to work and scans and senses the surrounding wireless signals. Collect wireless network signal information in the current environment, including signal strength, signal type (such as 2.4GHz or 5GHz), signal quality, etc. A series of networking information obtained by sensing will be used for subsequent network status judgment. Determine whether the networking information is a preset state value to determine whether the vehicle diagnostic instrument is in a network available state. Compare the networking information collected in step S111 with the preset state value. The preset state value can be a signal strength threshold, a signal quality standard, or a specific network configuration requirement. Determine whether the vehicle diagnostic instrument is in a network environment where wireless communication can be performed normally. If the networking information meets the preset state value, it is determined that the vehicle diagnostic instrument is in a network available state, and the subsequent diagnostic process can continue to be executed. If the network information does not meet the preset status value, it may be necessary to perform network configuration adjustment, signal enhancement or other troubleshooting steps to ensure that the vehicle diagnostic instrument can successfully connect to the network. Through steps S111 and S112, the vehicle diagnostic instrument can self-detect the network status to ensure good network communication conditions before starting diagnosis. Judging the network status in advance can prevent diagnostic failures or data transmission errors caused by network problems. Fast network status detection and automatic adjustment can improve the user experience and reduce waiting time caused by network problems. Through these specific implementation steps, the vehicle diagnostic system can complete the vehicle's diagnostic tasks more intelligently and efficiently.

[0037] In a more specific embodiment, before executing method S120, the method further specifically includes executing steps S121-S122:

[0038] S121, storing the diagnostic item information of the vehicle diagnostic instrument in a database to create a sequence to be started;

[0039] S122: Arrange the diagnostic agenda for the vehicle diagnostic instruments in the startup sequence according to the matching degree between the diagnostic item information of the vehicle diagnostic instruments and the requirements to be diagnosed.

[0040] Specifically, in a more specific embodiment, the diagnostic project information of the vehicle diagnostic instrument is stored in the database to create a sequence to be started, and the vehicle diagnostic instrument stores all the diagnostic project information it supports, such as the name of the diagnostic module, function description, diagnostic parameters, etc., in a central database or a local database. A clear list of diagnostic projects is established to provide data support for the subsequent diagnostic process. A sequence to be started is created in the database, which contains all available diagnostic projects and their detailed information. According to the degree of matching between the diagnostic project information of the vehicle diagnostic instrument and the requirements to be diagnosed, the vehicle diagnostic instruments in the sequence to be started are arranged in a diagnostic agenda, and the system matches and analyzes the diagnostic project information in the database according to the user's diagnostic requirements, such as specific fault codes, vehicle models, maintenance history, etc. Determine which diagnostic projects need to be executed first and their execution order. High-priority projects may include those that directly affect vehicle safety or major functions. Projects with a high degree of matching will be arranged at the front of the sequence to ensure that the most relevant diagnosis is executed first. Considering the diagnostic efficiency and resource allocation system may optimize the arrangement according to factors such as the complexity of the project and the execution time. By matching the specific diagnostic needs of the user, the system can provide a personalized diagnostic agenda to improve the pertinence and efficiency of the diagnosis. The rational arrangement of the diagnostic agenda helps to reduce unnecessary diagnostic steps, shorten diagnostic time and improve overall work efficiency. By prioritizing the execution of key diagnostic projects, the system can more effectively utilize the resources of the vehicle diagnostic instrument to ensure that the most important diagnostic tasks are completed within a limited time. Through these steps, the vehicle diagnostic system can achieve an orderly and efficient diagnostic process, thereby improving the overall level of automobile maintenance and service.

[0041] In a more specific embodiment, vehicle computer diagnostic information of each diagnostic module is obtained, and judging whether the vehicle computer diagnostic instrument is in a diagnostic function operation state according to the vehicle computer diagnostic information includes sensing available signals of the vehicle computer diagnostic instrument to obtain the vehicle computer diagnostic information; judging whether the vehicle computer diagnostic information is a preset state value to determine whether the vehicle computer diagnostic instrument is in a network available state.

[0042] In a more specific embodiment, a diagnostic module with a diagnostic function running state is selected to be added to a diagnostic scheduling sequence, including storing the diagnostic project information of the vehicle diagnostic instrument in a database to create a diagnostic scheduling sequence; and arranging the diagnostic agenda of the vehicle diagnostic instrument in the diagnostic scheduling sequence according to the degree of matching between the diagnostic project information of the vehicle diagnostic instrument and the requirements to be diagnosed.

[0043] Prioritizing the diagnostic modules in the sequence to be started and the diagnostic modules in the diagnostic scheduling sequence to obtain the first priority sequence and the second priority sequence respectively includes assigning urgency priority to the diagnostic project information of each vehicle diagnostic instrument in the sequence to be started and the diagnostic project information of the diagnostic modules in the diagnostic scheduling sequence; arranging the priorities according to the urgency priority values ​​to obtain the first priority sequence corresponding to the sequence to be started and the second priority sequence corresponding to the diagnostic scheduling sequence. Matching the diagnostic modules in the first priority sequence with the diagnostic modules in the second priority sequence to generate vehicle diagnostic result information includes: obtaining the diagnostic project information of at least one diagnostic module in the first priority sequence as primary target diagnostic project information; obtaining the diagnostic project information of at least one diagnostic module in the second priority sequence as advanced target diagnostic project information; matching the primary target diagnostic project information with the advanced target diagnostic project information to generate vehicle diagnostic result information; and sending the vehicle diagnostic result information to the diagnostic box for diagnostic information storage.

[0044] Specifically, in a more specific embodiment, the operation process of the vehicle diagnostic system is further refined to ensure the correct execution and efficient management of the diagnostic function. Obtain vehicle diagnostic information and determine the operating status of the diagnostic function. Perform available signal sensing on the vehicle diagnostic instrument to obtain vehicle diagnostic information. The vehicle diagnostic instrument detects surrounding wireless signals through a built-in sensor or network module to obtain vehicle diagnostic information. Determine whether the vehicle diagnostic information is a preset state value to determine whether the vehicle diagnostic instrument is in a network available state. The system compares the acquired vehicle diagnostic information with the preset state value to determine whether the vehicle diagnostic instrument is in a network available state. If the information matches the preset state value, it is considered that the diagnostic instrument is in an operational state. Select the diagnostic module with the operating status of the diagnostic function to add it to the diagnostic scheduling sequence, store the diagnostic project information of the vehicle diagnostic instrument in the database to create a diagnostic scheduling sequence, and the diagnostic project information of the vehicle diagnostic instrument is stored in the database, and a diagnostic scheduling sequence is created accordingly. According to the matching degree between the diagnostic item information of the vehicle diagnostic instrument and the requirements to be diagnosed, the vehicle diagnostic instruments in the diagnostic scheduling sequence are arranged for diagnostic agenda. The system sorts the items in the diagnostic scheduling sequence according to the matching degree between the diagnostic item information and the actual diagnostic requirements to determine the priority and order of diagnosis. Prioritize the diagnostic modules, assign the diagnostic item information of each vehicle diagnostic instrument in the sequence to be started and the diagnostic item information of the diagnostic modules in the diagnostic scheduling sequence to the urgency priority respectively, and the system assigns a priority value to each item according to the urgency of the diagnostic item. Prioritize according to the urgency priority assignment to obtain the first priority sequence corresponding to the sequence to be started and the second priority sequence corresponding to the diagnostic scheduling sequence. The system sorts the diagnostic items according to the size of the assignment to form two priority sequences. Match the diagnostic modules to generate vehicle diagnostic result information, obtain the diagnostic item information of at least one diagnostic module in the first priority sequence as the primary target diagnostic item information, and select the information of at least one diagnostic module from the first priority sequence as the target of preliminary diagnosis. Obtain the diagnostic item information of at least one diagnostic module in the second priority sequence as the advanced target diagnostic item information, and select the information of at least one diagnostic module from the second priority sequence as the target of further diagnosis. The primary target diagnostic item information is matched with the advanced target diagnostic item information to generate the vehicle computer diagnostic result information. The system matches the diagnostic item information in the two sequences to generate comprehensive diagnostic result information. The vehicle computer diagnostic result information is sent to the diagnostic box for diagnostic information storage. The generated diagnostic result information is sent to the diagnostic box and stored therein for subsequent analysis and processing. Through the priority arrangement and matching process, it is ensured that key diagnostic items are given priority, improving the accuracy and efficiency of diagnosis. The system sorts the diagnostic items according to their urgency and matching degree, optimizing the allocation of diagnostic resources.By storing the diagnostic result information in the diagnostic box, the system can manage and analyze diagnostic data more effectively to provide support for maintenance.
