Description

[0002] With the booming development of smart devices and the increasing prevalence of smart modules, smart homes, smart security, and smart energy are being implemented on a large scale, leading to an exponential surge in the number of smart devices. However, the increasing complexity of device hardware and software, along with the more diverse operating environments, has resulted in frequent issues during actual use. On the one hand, program execution often encounters anomalies, such as crashes, infinite loops, and module failures; on the network side, Wi-Fi or BLE link failures cause network disconnections; and system resources are often excessively consumed, resulting in abnormal CPU, memory, and RF channel usage.

[0029] The following is combined with Figures 2-4 The present invention describes a method for recovering from anomalies in smart devices.

[0030] Figure 2 This is one of the flowcharts illustrating the intelligent device anomaly recovery method provided by this invention. For example... Figure 2 As shown, the method includes the following: Step 201: Determine if a malfunction has occurred.

[0031] A fault is a state in which a smart device is unable to perform its expected functions due to hardware abnormalities, software crashes, or external interference. Examples include program crashes, network disconnections, abnormal main business functions, and radio frequency abnormalities.

[0032] In practice, intelligent devices can determine that they have malfunctioned in various ways, and are not limited by the description in this manual.

[0033] Step 202: Obtain the black-box summary information of the fault status data at the current moment.

[0034] Fault status data is quantitative information recording the operating parameters of equipment when a fault occurs. Fault status data may include, but is not limited to: The complete crash stack describes the call hierarchy information at the time of the program crash, which is used to locate the crash location.

[0035] Network and radio frequency statistics include network connection quality (such as RSSI, SNR) and wireless communication status (such as Wi-Fi channel, BLE connection count).

[0036] Recent business process data is used to record key business process nodes recently executed by the device.

[0037] Register snapshots are used to capture the values ​​of CPU registers (such as PC and SP) at the time of a crash, aiding in the analysis of the cause of the crash.

[0038] Sensor / peripheral status snapshots are used to record the real-time status of device peripherals (such as temperature and accelerometer data).

[0039] In the specific implementation process, after the intelligent device determines that it is in an abnormal state, it initiates the following self-rescue mode: stops non-critical business; starts a minimized operating environment; analyzes the source of the abnormality trigger; and obtains black-box summary information of the fault status data based on the source of the abnormality trigger.

[0040] As an example only, smart devices can extract the following key data from fault status data to form black-box summary information: register snapshot, crash stack fingerprint, main service call chain summary; network connection status, radio frequency status (BLE / Wi-Fi channel, Tx / Rx status); most recent uptime; block health, such as the operating status of "Bluetooth stack / sensor driver / service module", etc.

[0041] The register snapshot may include, but is not limited to, the following data: PC (Program Counter), which stores the address of the next instruction to be executed; LR (Link Register), which stores the function return address (used when a subroutine is called); SP (Stack Pointer), which points to the top address of the current stack; and xPSR (Extended Program Status Register), which contains condition flags (such as the zero flag and carry flag) and status information.

[0042] The network connection status may include, but is not limited to, the following data: RSSI (Received Signal Strength Indicator), which measures the power strength of the wireless signal (unit: dBm); SNR (Signal-to-Noise Ratio), which represents the ratio of signal power to noise power (unit: dB); AP (Access Point), which is the central node in a wireless local area network (such as a Wi-Fi router); BSSID (Basic Service Set Identifier), which is the MAC address of the wireless access point (uniquely identifying the AP).

[0043] The radio frequency status may include, but is not limited to, the following data information: BLE (Bluetooth Low Energy), a short-range wireless communication technology (suitable for low-power devices); Tx / Rx (Transmit / Receive), describing the communication direction of the wireless device (Tx for transmitting, Rx for receiving).

[0044] The above black-box summary information has a lightweight structure, suitable for transmission via broadcast protocols.

[0045] After obtaining the black-box digest information, the smart device can generate a data fingerprint of the black-box digest information (e.g., hash value, CRC check value, etc.); based on the data fingerprint of the black-box digest information, an anomaly rescue request can be generated.

[0046] After receiving an abnormal rescue request, the network interconnection device uses the data fingerprint of the black box digest information carried in the abnormal rescue request as a key to read the black box digest information from the smart device.

[0047] Network interconnection devices are hardware / software systems that enable data exchange or protocol conversion between different devices or subnets within a local area network (LAN). Examples of network interconnection devices include smart gateways and user terminals.

[0048] In some embodiments, the smart device is a Bluetooth Low Energy (BLE) device, which can construct a broadcast packet based on the data fingerprint of the black-box digest information; wherein the broadcast packet carries the data fingerprint of the black-box digest information and the rescue communication endpoint of the smart device; a preset General Attribute Profile Service Identifier (GATT ServiceUUID) is written into the broadcast packet to obtain an abnormal rescue request; wherein the General Attribute Profile Service Identifier carries a first self-rescue service identifier; the first self-rescue service identifier is used to identify the broadcast packet as an abnormal rescue request.

[0049] Rescue communication endpoints are logical or physical nodes that intelligent devices can use for information exchange in the event of a failure.

[0050] For example, in BLE (Bluetooth Low Energy) communication, the rescue communication endpoint can be a rescue connection channel established through advertising channels or specific service channels (e.g., GATT-based service channels).

[0051] For example, in a Wi-Fi network, the rescue communication endpoint could be a TCP / UDP port used for emergency communication or device management.

[0052] In some embodiments, the broadcast packet may also carry an exception type code indicating a malfunction in the smart device and an identifier required for OTA (Over-The-Air) proxying. The exception type code can be initially determined by the smart device based on black-box summary information. The identifier required for OTA proxying is used for subsequent OTA upgrades.

[0053] In the specific implementation process, the intelligent device can write the data fingerprint of the black box summary information, the rescue communication endpoint, the anomaly type code, and the identifier required by the OTA agent into the Vendor Specific field of the BLE broadcast packet; and set the first self-rescue service identifier in the preset field of GATT ServiceUUID.

[0054] After receiving the broadcast packet, the network interconnection device uses the Bluetooth Low Energy GATT service to read the black box digest information from the rescue communication endpoint of the smart device, using the data fingerprint of the black box digest information as a key.

[0055] In the embodiments provided by the present invention, by broadcasting the broadcast packet constructed in the above manner within the device's local area network, the network interconnection device can detect the broadcast packet without the need for network configuration, and learn from the broadcast packet that the smart device has malfunctioned and needs rescue.

[0056] In some embodiments, the smart device is a Wi-Fi device, which can construct a Wi-Fi management frame based on the data fingerprint of the black-box summary information to obtain an abnormal rescue request; wherein, the vendor-specific information element field (Vendor IE) of the Wi-Fi management frame contains the data fingerprint of the black-box summary information, the rescue communication endpoint of the smart device, and the second self-rescue service identifier; wherein, the second self-rescue service identifier is used to identify that the Wi-Fi management frame is an abnormal rescue request.

[0057] In practice, Wi-Fi management frames, such as Beacon / Probe Response frames, carry a custom Vendor IE. The Vendor IE may contain: a data fingerprint of black-box summary information, a rescue communication endpoint (e.g., rescue port number UDP 5353), a second self-rescue service identifier, an exception type code of the smart device failure, and the identifier required by the OTA (Over-The-Air) proxy.

[0058] In the embodiments provided by the present invention, by constructing the Wi-Fi management frame in the above manner, the network interconnection device can detect the Wi-Fi management frame without affecting the existing network structure and without the smart device needing to actively connect to the AP (Access Point), thereby knowing that the smart device has malfunctioned and needs rescue.

[0059] After receiving the Wi-Fi management frame, the network interconnection device uses the Wi-Fi protocol to read the black box digest information from the rescue communication endpoint of the smart device, using the data fingerprint of the black box digest information as a key.

[0060] Step 203: Broadcast an anomaly rescue request within the device's local area network.

[0061] In practice, smart devices can broadcast emergency rescue requests within the device's local area network using various common methods, without being limited by the descriptions in this manual.

[0062] After detecting an abnormal rescue request broadcast, the network interconnection device establishes a connection with the smart device and reads the black box summary information from the smart device.

[0063] Step 204: Receive the update packet sent by the network interconnection device.

[0064] An update package is a software or firmware upgrade file containing fault fixes, such as a differential patch or a full firmware image. The update package corresponds to black-box summary information; it is received from the cloud server after the network-connected device reports the black-box summary information.

[0065] In practice, the update package may be an existing patch or version package for the black-box summary information, or a patch or version package generated by relevant personnel based on the black-box summary information, and is not limited to the description in this manual.

[0066] Step 205: Perform an online upgrade based on the update package.

[0067] In practice, network interconnection devices can act as OTA agents to guide smart devices to perform online upgrades based on update packages.

[0068] After completing the online upgrade, the smart device exits the self-rescue mode, goes back online, and resumes normal operations.

[0069] Figure 3 This is the second flowchart illustrating the intelligent device anomaly recovery method provided by this invention. This method is executed by network interconnection devices in the device's local area network, such as... Figure 3 As shown, the method includes the following: Step 301: Detect the broadcast of an abnormal rescue request, establish a connection with the smart device broadcasting the abnormal rescue request, and read the black box summary information from the smart device; wherein, the abnormal rescue request is broadcast by the smart device after it determines that it has malfunctioned; the black box summary information is obtained by the smart device after it determines that it has malfunctioned.

[0070] For a detailed description of the abnormal rescue request and black-box summary information, please refer to the relevant content in steps 202 and 203, which will not be repeated here. In practice, network interconnection devices can scan for broadcast services within the device's local area network at preset time intervals; once any broadcast service carrying a self-rescue service identifier is detected, the rescue process is triggered.

[0071] In some embodiments, an abnormal rescue request is obtained by writing a preset general attribute profile service identifier into a broadcast packet. The broadcast packet is constructed by the smart device based on the data fingerprint of the black-box digest information. The broadcast packet carries the data fingerprint of the black-box digest information and the rescue communication endpoint of the smart device. The general attribute profile service identifier carries a first self-rescue service identifier. The first self-rescue service identifier is used to identify the broadcast packet as an abnormal rescue request. For a detailed description of this embodiment, please refer to the relevant content in step 203, which will not be repeated here.

[0072] In this embodiment, a broadcast packet carrying a general attribute profile service identifier can be parsed based on an abnormal rescue request. The attribute profile service identifier carries a first self-rescue service identifier. A connection is established with a smart device through the Bluetooth Low Energy (GATT) service.

[0073] In some embodiments, the abnormal rescue request is constructed by creating a Wi-Fi management frame based on the data fingerprint of the black-box digest information. The vendor-specific information element field of the Wi-Fi management frame includes the data fingerprint of the black-box digest information, the rescue communication endpoint of the smart device, and a second self-rescue service identifier. The second self-rescue service identifier is used to identify the Wi-Fi management frame as an abnormal rescue request. For a detailed description of this embodiment, please refer to the relevant content in step 203, which will not be repeated here.

[0074] In this embodiment, after parsing the Wi-Fi management frame according to the abnormal rescue request, the network interconnection device can establish a connection with the smart device through the Wi-Fi protocol (e.g., SoftAP mode or direct connection mode).

[0075] In practice, network interconnection devices can use the data fingerprint of the black box digest information as a key to read the black box digest information from the rescue communication endpoint of the smart device.

[0076] Step 302: Report the black-box summary information to the cloud server.

[0077] In the specific implementation process, the cloud server can complete the following tasks based on the uploaded black-box summary information: anomaly classification (including crash type matching and business flow anomaly identification), cause inference (through register pattern matching and business flow comparison analysis), patch matching (comparison with the version repository), and decision on the distribution of available OTA update packages.

[0078] If no available update package is available, the cloud server can push black box summary information to relevant personnel to assist in locating and generating the update package.

[0079] Step 303: Receive the update package from the cloud server; wherein the update package corresponds to the black-box summary information.

[0080] Update packages are software or firmware upgrade files containing bug fixes, such as differential patches or full firmware images. Update packages correspond to black-box summary information.

[0081] In practice, the update package may be an existing patch or version package for the black-box summary information, or a patch or version package generated by relevant personnel based on the black-box summary information, and is not limited to the description in this manual.

[0082] Step 304: Send the update package to the smart device to instruct the smart device to perform an online upgrade operation based on the update package.

[0083] Figure 4 This is the device local area network provided by the present invention. For example... Figure 4 As shown, the device local area network 400 includes a smart device 410 and a network interconnection device 420; wherein, the smart device 410 and the network interconnection device 420 perform the following interactive operations: The intelligent device determines that it has malfunctioned.

[0084] Obtain the black-box summary information of the fault status data at the current moment.

[0085] Broadcast an emergency rescue request within the device's local area network.

[0086] The network interconnection device detects the broadcast of an abnormal rescue request, establishes a connection with the smart device, and reads black-box summary information from the smart device.

[0087] The black-box summary information is reported to the cloud server.

[0088] Receive an update package from the cloud server; wherein the update package corresponds to the black-box summary information.

[0089] The update package is sent to the smart device.

[0090] The smart device receives the update package.

[0091] Based on the update package, perform an online upgrade.

Figure 5 As shown, the intelligent device anomaly recovery device 500 includes the following modules: The determination module 510 is used to determine if a fault has occurred within itself.

[0095] The acquisition module 520 is used to acquire the black-box summary information of the fault status data at the current moment.

[0096] The broadcast module 530 is used to broadcast an abnormal rescue request within the device's local area network; wherein, after the network interconnection device detects the broadcast of the abnormal rescue request, it establishes a connection with the smart device and reads the black box summary information from the smart device.

[0097] The receiving module 540 is configured to receive an update packet sent by the network interconnection device; wherein the update packet corresponds to the black box summary information; the update packet is received from the cloud server after the network interconnection device reports the black box summary information to the cloud server.
