[0045] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0046] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.

[0047] In the field of IoT, cellular devices (also called cellular wireless transmission devices) are key components for realizing IoT communication connections and are widely used in various IoT scenarios. These devices usually need to operate 24 / 7, unattended, and rely on reliable network connections to ensure stable data transmission. Therefore, the stability of the cellular communication network and the ability to quickly and accurately locate cellular device operation problems are crucial to the efficient operation of the IoT system.

[0048] However, existing equipment fault diagnosis methods have certain limitations. These methods usually rely on key operation logs of core functions to locate equipment problems. When an embedded cellular device has an abnormality, although the key operation logs can be stored to determine the on-site equipment problem, this method is not conducive to effectively distinguishing equipment problems from business problems. This makes it difficult to quickly and accurately locate the root cause of the problem in actual operation and maintenance, thus affecting the overall operation and maintenance efficiency and stability of the system.

[0049] To solve the above problems, the present application embodiment proposes a self-diagnosis method for a cellular device. Figure 1The figure is a schematic diagram of the implementation scenario of the method. The implementation scenario includes a device management platform (DMP in English, the full name is Device Management Platform in English), an application management platform (AMP in English, the full name is Application Management Platform in English), a gateway (GW in English, the full name is Gateway in English) and a storage device. Among them, the device management platform and the application management platform can push information to each other, the device management platform and the gateway can communicate through HMP (Human Monitor Protocol), and the application management platform and the gateway can communicate through TCP protocol, MQTT protocol or GB28281 protocol.

[0050] The gateway may include a peripheral interface, which may include at least one of an RJ45 interface, an RS232 interface, an RS485 interface, a USB interface, and a TF card interface. Among them, the RJ45 interface, the RS232 interface, and the RS485 interface can be used to access serial terminals such as IoT devices so that the IoT devices can be connected to the network through the gateway, or can also be connected to a lower computer, and the lower computer includes a camera and a PC. The USB interface and the TF card interface can be used to access external storage devices, including U disks, TF cards, etc. The application can be encrypted through an external storage device. In addition, the gateway may also include a wireless communication module, and the network is accessed through the wireless communication module. The wireless communication module may include a Wifi module, a 4G module, or a 5G module. After the gateway is connected to the network, the gateway can transmit data to the device management platform or the application management platform according to different needs. For example, data such as device status information, device attribute data, and device operation log data can be transmitted to the device management platform. Data such as business data, analysis data, control instruction feedback data, and application logs are transmitted to the application management platform.

[0051] The application management platform and the device management platform can communicate through the API to conduct joint analysis of faults, thereby obtaining more accurate fault location results.

[0052] The log information in the embodiment of the present application may include at least one of startup log information, initialization log information, wireless test log information, peripheral interface log information, application application log information and other log information.

[0053] The startup log may include boot startup log information and kernel startup log information, and the initialization log information may include the initialization log information of the gateway. Figure 2In the log information storage diagram when the gateway is started, when the gateway is started, the startup log information and the initialization log information can be stored locally, that is, stored locally in the gateway. After the gateway is started, it can be detected whether the gateway is connected to the network. If the gateway is connected to the network, the startup log information and the initialization log information can be sent to the device management platform. If the gateway is not connected to the network, the log information can be exported through an external storage device, including the export of the startup log information and the initialization log information, so that the log information can be effectively saved in the event of a power outage.

[0054] After the gateway is powered on, it enters the boot and kernel startup stages. In the initialization stage, environment variables are loaded, functions are pulled up, interfaces are mounted, etc. In order to accurately monitor the stability of the system, the log information of the gateway startup is stored and monitored. If the startup log information determines that the startup speed is slower than normal, or other abnormalities occur during the startup, it can be obtained remotely through the device management platform after the gateway is restored or the startup is completed, or exported and analyzed locally through the network port / serial port / USB port, etc.

[0055] After the gateway is started, Figure 3 In the log information storage process diagram shown, the log management system in the gateway obtains the device log information and business log information of the gateway. When it is detected that the gateway is connected to an external storage device, the device log information and business log information are stored in the external storage device of the gateway. If the gateway is not connected to an external storage device, the log information, including the device log information and the business log information, can be stored in the local storage device of the gateway. When the log information is stored in the local storage device, the frequency of writing log data to the local storage device can be increased by polling the memory size when the memory usage is high to reduce the amount of log information cached in the memory; or, a batch write operation of the log information can be triggered to free up memory space. If the memory usage is low, the frequency of writing log information to the local storage can be reduced to avoid frequent disk I / O operations affecting system performance.

[0056] After the log information is stored, it can be detected whether there is an abnormality in the log information. If there is an abnormality, the log information with the abnormality can be sent to the management platform, including sending the abnormal device log information to the device management platform and sending the abnormal business log information to the application management platform. If there is no abnormality in the log information, it can be stored locally on the gateway and can be used for the device management platform and the application management platform to call.

[0057] After the device is initialized, the gateway can be connected to the external storage device. After the internal system functions are running normally, the log management system will also be running. The core application of the log management system is to manage the logs of all functional units in the gateway, perform statistics according to the time unit function, and read the log information according to the predetermined storage rules and the predetermined reading rules. The reading rules can include active log push and passive log storage reading according to the difference in log levels.

[0058] For example, the log level can include full log level, business log level and exception log level. Among them, the full-time level log information is used to store all the operation status of the gateway from startup to power-off. The business log level log information is used to store the core business communication content log, such as the channel data transmission of the data transmission unit (DTU), the operation status and data status of the container application (DOCKER APP), etc. Abnormal log level: system log with abnormal fields. Business alarm log, etc.

[0059] Log information of different levels can be stored according to pre-set storage priorities.

[0060] For example, the storage priority can be: First, the log management system will determine the best log storage condition. The best log storage condition is the external storage device of the gateway, and then it is stored in the local storage device of the gateway, and then it is stored in the management platform. External storage devices can include USB flash drives, TF cards, and customer lower-level computer storage, etc. USB flash drives and TF cards belong to the content of the gateway interface department, and logs can be directly stored in USB flash drives and TF cards through the log management system. Lower-level computer logs need to be transmitted based on the southbound unified interface protocol. For example, between the serial port device in the gateway and the Ethernet device, the log information monitored by the gateway can be transmitted to the lower-level computer through TCP / IP. When the log management system detects that the various functions of the system have abnormal log information output, the stored abnormal log information can be sent to the device management platform or application management platform according to the current network situation, or stored in the local storage device of the gateway.

[0061] After the gateway establishes a link with the built-in northbound protocol and the management platform, it regularly packages and compresses the log information stored in the gateway and transmits it to the northbound management platform in a scheduled manner or according to the size of the log data packet (that is, only one of the time and size needs to be met to trigger active reporting).

[0062] In the passive upload mode, the management platform can issue log information acquisition instructions, and the log information can be reported on demand according to the instructions.

[0063] The wireless test log information may include the operating status information of the modem (moden), Wifi module, and Wan module, the operating performance information of the modem (moden), Wifi module, and Wan module, and the network judgment key log information of the modem (moden), Wifi module, and Wan module.

[0064] The peripheral device interface log information may include interface connection status log information and peripheral device operation status management log information.

[0065] The application log information may include application running status detection information and application running data packet information.

[0066] Other log information may include VPN log information and time synchronization log information.

[0067] In addition, the gateway in the embodiment of the present application can also determine whether the device management platform is running normally through the device management platform application. If the device management platform is running normally, the log information of the device management platform application can be stored locally in the gateway. If the device management platform is not running normally, the abnormal device log information can be pushed to the AEB (application performance management) platform and stored locally in the gateway.

[0068] Figure 4 A schematic diagram of a self-diagnosis method for a cellular device according to an embodiment of the present application is provided. The system for self-diagnosis of a cellular device can be as follows: Figure 1 As shown, the first device may be a device management platform, and the second device may be a service management platform, or the first device may be an application management platform, and the second device may be a device management platform. The method includes:

[0069] In S401, the first management platform detects abnormal first log information.

[0070] The first management platform in the embodiment of the present application may be a device management platform, or may be an application management platform.

[0071] When the first management platform is a device management platform, the first log information of the abnormality detected may include abnormal information that the device management platform loses connection with the gateway. When the first management platform is an application management platform, the first log information of the abnormality detected may include abnormal information that the application management platform loses connection with the gateway.

[0072] In S402, second log information of the gateway is obtained through the second management platform according to the communication link between the first management platform and the second management platform.

[0073] When the device management platform detects the abnormal first log information that the device management platform has lost contact with the gateway, the device management platform can send a service query request to the application management platform based on the communication link between the device management platform and the application management platform to determine whether the service corresponding to the gateway is normal. If the service corresponding to the gateway is normal, it can indicate that the wireless channel of the gateway is normal. The application management platform can actively retrieve the second log information of the gateway. The second log information may include the device log information of the gateway and the service log information obtained by the application management platform. The log information of the gateway includes the status of the gateway and the abnormal log information of the gateway. The service log information obtained by the application management platform includes the service status information and the log information of the service abnormality. The application management platform pushes the second log information to the device management platform.

[0074] When the application management platform detects the abnormal first log information that the application management platform and the gateway have lost contact, it is assumed that the gateway and the application management platform transmit industrial data based on the modbus protocol through the TCP protocol. After the application management platform detects that the data collection issued based on the modbus protocol has timed out, the application management platform may think that there is a problem with the service transmitted based on the modbus protocol, but it cannot be determined whether the cellular disconnection of the gateway caused the TCP disconnection, or the lower computer crashed, causing the lower computer to receive data based on the modbus protocol without replying. Therefore, it is necessary to conduct a comprehensive analysis in combination with the first log information and the second log information.

[0075] In S403, the fault of the cellular device is located according to the first log information and the second log information.

[0076] In the embodiment of the present application, when an abnormal first log information is detected on the device management platform, such as when the device management platform is detected to be disconnected, the device management platform may send a query request to the application management platform based on the communication link between the device management platform and the application management platform to query whether the gateway's business is normal. If the gateway's business is normal, the gateway's second log information is obtained through the application management platform, and the second log information includes the gateway's log information and the gateway's business log information obtained by the application management platform. The first log information and the second log information may be input into a pre-trained first fault location model to determine the faults located by the first log information and the second log information.

[0077] The first fault location model can be trained based on sample data of the determined fault location, and the sample data includes the first log information, the second log information, and the fault location information corresponding to the first log information and the second log information. The first log information and the second log information are input into the first fault location model, so that the model calculates and outputs the fault location information, and the fault location information output by the model is compared with the fault location information in the sample data, and the first fault location model is adjusted according to the deviation between the two, until the deviation between the two meets the preset requirements, thereby completing the training of the first fault location model.

[0078] In the embodiment of the present application, when the application management platform detects abnormal first log information, such as when the business management platform detects that the business data is offline, including missing modbus data, the business management platform can determine whether the cellular device and the gateway are operating normally by communicating with the device management platform. If the communication is normal, the gateway log can be retrieved through the device management platform to analyze the reason why the modbus data inside the cellular device is not transmitted to the application management platform, that is, the gateway log is captured by the device management platform to analyze the fault point. If the device management platform is not online, that is, the device management platform is also offline, the fault point may be the gateway.

[0079] When the first log information includes a gateway collection instruction timeout, and the second log information obtained by the application management platform through the device management platform includes that the gateway is normal, the application management platform can locate the business fault according to the business log through the second log information including the business log of the gateway obtained by the device management platform.

[0080] Among them, locating a service fault based on the service log may include:

[0081] If the business log content includes that the cellular network status is normal and the lower computer communication link shows timeout or error, it means that the network function between the gateway and the management platform is not faulty, and there is a problem with the communication link between the gateway and the lower computer (such as serial port, network port, etc.).

[0082] If the business log information includes data format anomalies, such as when the gateway processes data and finds that the data format does not meet expectations, it may be that the data is parsed incorrectly or tampered with during data transmission. Or if there is a memory anomaly, such as a problem with the gateway's memory usage, it may be a memory leak, insufficient memory, or memory corruption. Then it can be determined that the gateway has an internal fault.

[0083] If the service log content includes TCP connection abnormalities, that is, there is a problem with the TCP connection between the gateway and the device management platform (DMP), which may be a connection interruption or connection abnormality, or a TCP connection network timeout, that is, the network connection delay between the gateway and the DMP is too high or completely interrupted, then it is determined that the gateway and the device management platform have communication failures.

[0084] Alternatively, in a possible implementation, the embodiment of the present application may also use a pre-trained second fault localization model to calculate the fault localization information corresponding to the first log information and the second log information.

[0085] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
