Background Art

[0002] Some old devices may have faults such as non-hot-pluggable USB or inability to reset, which require R & D personnel to go to the site for troubleshooting and repair, consuming a large amount of human and material resources and having low efficiency.

Therefore, it is impossible to determine whether a device is inserted into a certain USB port, and it is impossible to monitor USB exceptions and perform automatic soft repair.

[0050] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] Referring to Figure 1 , a flowchart of steps of a USB exception monitoring and automatic soft repair method based on HarmonyOS provided by an embodiment of the present invention is shown, and specifically may include the following steps:

[0052] Step 101, identify the current USB fault type; the USB fault type includes soft faults and hard faults;

[0053] Step 102, if the current USB fault type is a hard fault, notify the R & D personnel to repair the hard fault;

[0054] Step 103: If the current USB fault type is a soft fault, import the USB basic resource information of HarmonyOS, and based on the USB basic resource information, find the key-value pair relationship between the VID, PID, and the USB port, and perform a reset or dynamic configuration according to the search result.

[0055] The present invention monitors the USB to promptly detect USB anomalies and accurately identify the USB fault type, distinguishing whether the USB fault is a soft fault or a hard fault. When the system detects a USB fault, it immediately determines the fault type. If it is determined to be a hard fault, which usually means there is a hardware-level damage or physical connection problem, the system will promptly notify the R & D personnel to intervene and repair. Since hard faults often involve the replacement or repair of hardware entities, professional on-site handling is required. By promptly notifying the R & D personnel, it can ensure that hard faults are resolved quickly and professionally, thus maintaining the stability and reliability of the entire system.

[0056] If the system identifies the USB fault as a soft fault, it will start an automated repair process based on HarmonyOS. First, import the USB basic resource information of HarmonyOS, which contains detailed information about the USB device, including the device's vendor ID, product ID, device path, USB interface, and endpoints. The system will then, based on this basic resource information, deeply search for the key-value pair relationship between the VID, PID, and the USB port. This search process is a crucial step in the automated repair and can help the system accurately locate the problematic USB device and port. Once the problem is found, the system will perform a reset operation or make dynamic configuration adjustments according to the preset strategy to attempt to restore the normal function of the USB. This process requires no manual intervention and greatly improves the efficiency and accuracy of fault repair.

[0057] In the automated repair process of soft faults, the asynchronous dual-process technology is adopted. For different search result situations, the corresponding process is selected for asynchronous processing, that is, perform a reset or dynamic configuration according to different search results, and the unselected process can be not started, saving the consumption of system space and power.

[0058] It can be seen that the method of the present invention can automatically identify whether it is a soft fault or a hard fault. For soft faults, through the asynchronous dual-process technology, it monitors USB anomalies and performs automated soft repair, improving the repair efficiency of USB soft faults, being imperceptible to users, enhancing the user experience, and eliminating the need for R & D personnel to travel to the site to troubleshoot and repair soft faults, saving a large amount of manpower and material resources.

[0059] In an optional embodiment of the present invention, identifying the current USB fault type includes:

[0060] Load the preset battery information access module and obtain the current voltage through the battery information access interface;

[0061] Judge whether the current USB fault type is a soft fault or a hard fault according to the current voltage.

[0062] In this embodiment, in order to identify the current USB fault type, a preset battery information access module can be loaded, the current voltage can be obtained through the battery information access interface, and it can be judged whether the current USB fault type is a soft fault or a hard fault according to the current voltage. The specific implementation method is as follows: load the battery information access module through "import batteryInfo from '@ohos.batteryInfo';", and then obtain the current voltage value through the batterySOC interface. If the obtained voltage value is greater than 0, it is determined that the current USB fault type is a soft fault; if the voltage value is less than or equal to 0, it is determined to be a hard fault. Different types of USB faults can be effectively distinguished by this method, providing an accurate basis for subsequent fault handling.

[0063] In an alternative embodiment of the present invention, import the USB basic resource information of HarmonyOS, including:

[0064] Load the preset USB basic resource information access module, obtain the USB device list through the USB device list acquisition interface, and traverse the USB device list to parse the VID information and PID information.

[0065] In this embodiment, in order to import the USB basic resource information of HarmonyOS, a preset USB basic resource information access module can be loaded, the USB device list can be obtained through the USB device list acquisition interface, and the USB device list can be traversed to parse the VID information and PID information. The specific implementation method is as follows: load the preset USB basic resource information access module through "import usb from '@ohos.usbManager'", import the USB basic resources related to HarmonyOS, and then obtain the USB device list through the getDeviceList interface. Then, perform a for loop traversal operation on the device list, parse the VID of each device through the idVendor() method, and parse the PID through the idProduct() method. In addition, the device path information and other related device information (such as device name, serial number, etc.) can also be parsed through the getDevicePath method.

[0066] In an alternative embodiment of the present invention, according to the USB basic resource information, find the key-value pair relationship between the VID, PID and the USB port, and perform a reset or dynamic configuration according to the search result, including:

[0067] Check whether the VID information and PID information of the USB device are empty;

[0068] If the VID information and PID information are not empty, query the database to determine whether there is a key-value pair of VID information and PID information and the USB port;

[0069] If the database has a key-value pair of VID information, PID information and the USB port, perform a reset operation on the bound USB port according to the key-value pair of VID information, PID information and the USB port; the key-value pair relationship of VID, PID and the corresponding USB port is obtained by listening to the USB plug-and-play broadcast of the system in advance and binding the PID, VID and the corresponding port position.

[0070] For the automatic repair of soft faults, the present invention first realizes efficient monitoring and processing through Process 1. The focus of Process 1 is on the real-time monitoring of the system USB plug-and-play broadcast. When a USB device is inserted or removed, the service will immediately capture relevant events, and through the listening mechanism, dynamically bind the PID and VID of the device to the corresponding USB port position. This binding process is the basis for subsequent anomaly detection and repair, ensuring that the system can accurately track the connection status of USB devices and port ownership. Through the binding operation, the service can not only record the detailed information of the device (such as vendor ID, product ID, device path, USB interface and endpoints), but also quickly locate the problem port when the device is abnormal, providing data support for the targeted repair of soft faults.

[0071] After parsing the VID information and PID information, Process 1 first checks whether the VID and PID are empty. If both are not empty, further query the pre-constructed database to verify whether there is a USB port key-value pair corresponding to the VID / PID. The database pre-stores the mapping relationship between the VID / PID and the port of all recognized devices through historical listening data, enabling the query process to be completed quickly. If there is a matching key-value pair in the database, the system directly performs a reset operation on the target USB port according to the binding relationship, effectively solving the soft fault. This reset operation does not require user intervention and is completed asynchronously in the background, ensuring the continuity of device use.

[0072] Refer to Figure 2 , the specific process is as follows:

[0073] Judge whether the VID information and PID information are empty. If the VID information and PID information are not empty, continue to the next step;

[0074] Query the database to determine whether there is already a key-value pair relationship between the VID, PID, and the USB port. If it exists, then according to the binding relationship between the VID, PID, and the USB port, power on again for reset.

[0075] During the execution of Process 1, if Process 2 does not need to be started, then continue to execute Process 1; if Process 2 needs to be started (such as for dynamic configuration or other operations), then destroy Process 2 after Process 2 finishes execution, and continue to execute Process 1.

[0076] Through the above method, the USB soft fault problem can be effectively solved, while ensuring the stability of the system and the normal operation of the USB device.

[0077] In an alternative embodiment of the present invention, the method further includes:

[0078] If the database does not record the key-value pair of the VID information, PID information, and the USB port, then read and parse the configuration file under the preset system path, obtain the new key-value pair relationship of the VID, PID, and the USB port according to the modification records in the configuration file, perform the configuration of the USB device node symbol and the port power-on / off node based on the new key-value pair relationship of the VID, PID, and the USB port, and update the new key-value pair relationship of the VID, PID, and the USB port in the database.

[0079] Since Process 1 depends on the fixed binding relationship of the PID, VID, and the port, if the USB peripheral is replaced later, and it is detected that the PID and VID are not bound or the PID and VID are detected to change, it may cause the monitoring to fail or misjudge an exception, and then trigger an unnecessary port reset. For this reason, the present invention also designs Process 2 to further improve the flexibility and compatibility of the method of the present invention.

[0080] The first situation processed by Process 2: When the system detects that the VID and PID information of the current USB device exist but the database does not record the key-value pair with the port, Process 2 will be triggered. At this time, Process 2 will read the Usb.conf configuration file under the preset system path (such as / sys / ). This file records the modification records and key parameters of the historical USB device configuration. By parsing the information in the file, the system can deduce the new key-value pair relationship of the current device's VID, PID, and the USB port. Subsequently, Process 2 automatically completes the dynamic configuration of the USB device node symbol and the port power-on / off node according to the configuration content, and updates the new key-value pair relationship to the database. After completion, Process 2 is automatically destroyed, and Process 1 continues to execute to ensure efficient use of resources.

[0081] In an alternative embodiment of the present invention, the method further includes:

[0082] If the VID information and PID information are empty, read the device node symbols and port power-on / off node information predefined in the configuration file under the preset system path, automatically configure the device node symbols and port power-on / off node information, and write the mapping relationship between the device node symbols and port power-on / off nodes into the database after the configuration is completed.

[0083] Since Process 1 depends on the fixed binding relationship of PID, VID, and the port, if the USB peripheral is replaced later, and it is detected that the PID and VID are not bound or the PID and VID are detected to change, it may cause the monitoring to fail or misjudge an exception, and then trigger an unnecessary port reset. For this reason, the present invention also designs Process 2 to further improve the flexibility and compatibility of the method of the present invention.

[0084] The second situation processed by Process 2: If it is detected that the VID and PID information are empty, Process 2 is also activated. In this scenario, the system directly reads the device node symbols and port power-on / off node information predefined in the Usb.conf file, bypasses the PID / VID binding mechanism, and directly completes the port configuration according to the preset rules. After the configuration is completed, the system writes the mapping relationship between the device node and the port into the database to avoid triggering Process 2 repeatedly later. After updating the database, Process 2 is destroyed, and Process 1 continues to execute.
