[0002] With the increasing intelligence of home appliances, the need for recording and debugging their operating status is growing, making the preservation of log data generated during operation crucial. Existing solutions typically write this log data directly to serial ports or non-volatile storage. However, when multiple threads operate simultaneously within a home appliance, the log data generated by each thread needs to be written sequentially, resulting in frequent and inefficient write operations. Especially with large volumes of log data, this writing method is highly susceptible to data loss. Therefore, reducing the risk of log data loss in home appliances is a pressing technical problem that needs to be solved. Summary of the Invention

Since the log pool is located in volatile memory, the data writing speed is fast, enabling rapid response to the high-frequency log data generation needs of the home appliance and avoiding data loss due to frequent read / write operations or write delays. Furthermore, the process of reading and saving target log data from the log pool allows this log data to be persistently stored, providing a reliable data foundation for subsequent log data analysis. In summary, the technical solution proposed in this application, through efficient data capture, fast storage and writing, and flexible data preservation, can reduce the risk of log data loss in home appliances, achieve comprehensive monitoring and effective utilization of home appliance log data, and improve the reliability of home appliances and user experience.

However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0030] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily need to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0031] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the amount of data for the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "multiple" means two or more.

[0032] It should be noted that the log data storage method proposed in this application can be applied to home appliances, such as air conditioners, refrigerators, washing machines, etc.

[0033] To enable those skilled in the art to better understand this application, firstly, in conjunction with Figure 1An application scenario in one embodiment of this application will be described.

[0034] See Figure 1 The diagram illustrates an application scenario of an embodiment of this application.

[0035] In such Figure 1 In the application scenario shown, an air conditioning unit 101a, air conditioning unit 101b, and air conditioning unit 101c may be included in a home. To record and debug the operating status of each air conditioning unit, it is necessary to save the log data generated during operation. In existing solutions, each air conditioning unit typically saves log data to a mobile storage device 103 or local non-volatile memory 102a, 102b, 102c via serial port A, or to a cloud server 104 via network communication C (e.g., via WiFi access to the internet). However, when multiple threads are working simultaneously in the air conditioning unit, the log data generated by each thread needs to be written sequentially, resulting in frequent and inefficient write operations. Especially when the log data volume is large, this writing method is prone to log data loss. Therefore, this application proposes a log data storage scheme to reduce the risk of log data loss in air conditioning units.

[0036] The implementation details of the technical solutions in the embodiments of this application are described in detail below:

[0037] Reference Figure 2 A flowchart illustrating a log data storage method according to an embodiment of this application is shown. In this application, the log data storage method can be executed by a device with computing processing capabilities. (Refer to...) Figure 2 As shown, this log data saving method includes at least steps 210 to 230, which are described in detail below:

[0038] In step 210, target log data of each business thread in the target home appliance during its operation is obtained.

[0039] In this application, the business thread in the home appliance can refer to the business thread used to implement various functions of the home appliance, such as business threads including voice module, TFT module, sensor module, WiFi module, Ble module (i.e., Bluetooth Low Energy module), etc.

[0040] In this application, the acquisition of target log data of each business thread in the target home appliance during operation can be performed according to the following steps 211 to 212:

[0041] Step 211: In response to the startup of each business thread in the target home appliance, listen to the log data of each business thread during its operation.

[0042] Step 212: Filter the log data according to preset filtering conditions to obtain the target log data.

[0043] It is understandable that when each business thread in the target home appliance starts running, it will generate a series of log data. Therefore, the initial log data can be obtained by listening to the running process of each business thread.

[0044] In this application, the log data may include, but is not limited to, the following:

[0045] I. Error Log Data: Records error information that occurs during thread execution. This includes exception capture, error code, and error description. This data is crucial for diagnosing and troubleshooting home appliances.

[0046] 2. Warning Log Data: Records potential risks or abnormal behaviors that may cause problems. For example, resource usage approaching the limit, unstable network connection, etc.

[0047] III. Information Log Data: Records normal system operation information. This typically includes thread start and stop times, successful configuration loading, connection establishment, etc. This data helps to understand the overall operating status of home appliances.

[0048] IV. Debug Log Data: Used during the development and testing phases, this data records detailed internal state changes and variable values. In production environments, this data is usually disabled or restricted to minimize its impact on performance.

[0049] V. Performance Log Data: Records thread performance metrics such as execution time, memory usage, and CPU usage. This data is very useful for optimizing the system performance and resource management of home appliances.

[0050] VI. User Operation Log Data: Records user interactions with the device, including user input and command execution. This data helps analyze user behavior and improve user experience.

[0051] In this application, after monitoring the log data of each business thread during its operation, this data can be further filtered to extract target log data of significant importance. Through preset filtering conditions, log data that meets the criteria can be automatically identified and extracted, thereby more efficiently supporting problem monitoring and diagnosis.

[0052] In this application, the preset filtering conditions can be flexibly configured to adapt to different data analysis needs. These conditions can be graded according to the importance of log data. For example, error log data, warning log data, and information log data are considered high-priority data because they are directly related to the stability and performance of home appliance systems. Therefore, these types of log data are defined as high-level data and are prioritized for filtering and processing. In contrast, debug log data and user operation log data can be defined as low-level data. These log data are mainly used for debugging and user behavior analysis during the development phase, and their priority is relatively low.

[0053] In this application, this hierarchical screening mechanism can not only effectively filter out unnecessary log data noise, but also ensure that key log data is processed and analyzed in a timely manner, thereby improving the efficiency of log data management, helping to quickly locate and solve potential problems of home appliances, and thus ensuring the efficient and stable operation of home appliances.

[0054] Continue to refer to Figure 2 In step 220, the target log data is written into a log pool, which is a storage space pre-created in the volatile memory of the target home appliance.

[0055] In this application, a storage space can be pre-created in the volatile memory of the target home appliance as a log pool for temporarily storing and managing target log data of each business thread during operation. This effectively allows for the temporary storage and management of target log data from each business thread. Specifically, the fast read / write characteristics of volatile memory can be utilized to ensure that log data can be written efficiently, thereby improving the real-time performance of the system. Furthermore, the log pool proposed in this application can avoid frequent read / write operations to non-volatile memory, thus reducing the risk of log data loss in the home appliance.

[0056] In this application, the step of writing the target log data into the log pool can be performed according to the following steps 221 to 222:

[0057] Step 221: Determine whether the remaining storage space of the log pool is greater than or equal to the amount of the target log data.

[0058] Step 222: If the remaining storage space is greater than or equal to the amount of data, then write the target log data into the log pool.

[0059] In this application, step 223 may also be performed:

[0060] Step 223: If the remaining storage space is less than the amount of data, then discard the target log data.

[0061] In this application, the remaining storage space of the log pool is determined to ensure that new target log data can be effectively stored. When the remaining storage space of the log pool is detected to be greater than or equal to the amount of target log data to be written, this data can be safely written to the log pool, ensuring the integrity and timeliness of the target log data and providing reliable data support for subsequent log data analysis. When the remaining storage space of the log pool is insufficient to accommodate new target log data, this data is discarded to prevent the log pool from crashing due to storage space overflow and losing other log data. This reduces the risk of log data loss in home appliances and achieves secure management of log data storage and processing.

[0062] Continue to refer to Figure 2 In step 230, the target log data is read from the log pool and saved.

[0063] In this application, the step of reading the target log data from the log pool can be performed according to the following step 231:

[0064] Step 231: Read the target log data from the log pool periodically or quantitatively.

[0065] In this application, by reading target log data from the log pool periodically or according to a preset data volume, data overflow in the log pool can be prevented, ensuring that key log data is processed and saved in a timely manner, thereby providing reliable data support for subsequent home appliance status analysis and fault diagnosis.

[0066] In this application, before saving the target log data, the following step 240 may also be performed:

[0067] Step 240: Add a setting character to the target log data. The setting character is used to identify the data category of the target log data.

[0068] In this application, adding specified characters to the target log data before saving it can significantly improve the efficiency of log data management and analysis. Specifically, by setting characters to identify the specific categories of log data, such as data level or data type, users can quickly locate and identify different categories of log data during subsequent analysis. For example, in the target log data, the set characters can be "ERROR" or "INFO" to distinguish between error log data and information log data. This makes the classification of log data more intuitive, and can greatly shorten data processing time and improve the accuracy and efficiency of log data analysis when performing data filtering, sorting, and retrieval during subsequent log data analysis.

[0069] In this application, the saving of the target log data can be performed according to at least one of the following steps: 250, 260, and 270.

[0070] Step 250: Move the target log data to a mobile storage device for storage.

[0071] In this application, the target log data is moved to a mobile storage device for storage, which can be achieved through a serial communication channel between the target home appliance and the mobile storage device. For example... Figure 1 As shown, air conditioning devices 101a, 101b, and 101c move target log data from the log pool to mobile storage device 103 via serial port A.

[0072] Step 260: Move the target log data to the local non-volatile memory of the home appliance for storage.

[0073] In this application, the target log data is moved to the local non-volatile memory of the home appliance for storage, which can be achieved through a serial communication channel between the target home appliance and the local non-volatile memory. For example... Figure 1 As shown, air conditioning devices 101a, 101b, and 101c respectively move target log data from the log pool to local non-volatile storage devices 102a, 102b, and 102c via serial port A.

[0074] Step 270: Upload the target log data to the cloud server for storage.

[0075] In this application, the target log data is uploaded to a cloud server for storage, which can be done through a network communication channel (such as an internet communication channel connected via WiFi) between the target home appliance and the cloud server. For example... Figure 1 As shown, air conditioning devices 101a, 101b, and 101c upload target log data from the log pool to the cloud server 104 via network communication channel C.

[0076] Based on the technical solution proposed in this application, by acquiring target log data from each business thread in the target home appliance during its operation and writing it into a log pool pre-created in the volatile memory of the home appliance, important information during the operation of the home appliance can be captured in real time, ensuring the recording of key log data in the home appliance. Since the log pool is located in volatile memory, the data writing speed is fast, enabling rapid response to the high-frequency log data generation needs of the home appliance and avoiding data loss due to frequent read / write operations or write delays. Furthermore, the process of reading and saving target log data from the log pool allows this log data to be persistently stored, providing a reliable data foundation for subsequent log data analysis. In summary, the technical solution proposed in this application, through efficient data capture, fast storage and writing, and flexible data preservation, can reduce the risk of log data loss in home appliances, achieve comprehensive monitoring and effective utilization of home appliance log data, and improve the reliability of home appliances and user experience.

[0077] In this application, before step 270 above, that is, before uploading the target log data to the cloud server for storage, the following steps 271 to 272 may also be performed:

[0078] Step 271: Send a device registration request to the cloud server so that the cloud server can determine the target device code for the target home appliance based on the registration information of the target home appliance.

[0079] Step 272: Receive the target device code sent by the cloud server. The target device code is used to be added to a set position in the target log data to identify that the target log data belongs to the target home appliance.

[0080] In this application, the accurate attribution and efficient management of log data can be ensured by registering and assigning codes to home appliances before uploading data to the cloud server. Specifically, before uploading target log data, the target home appliance first sends a registration request to the cloud server, so that the cloud server assigns a unique target device code to it based on the registration information of the target home appliance. This code can be used to identify the device and ensure that each log data can be accurately associated with the target home appliance.

[0081] Once the target home appliance receives this code, it can add it to the designated location in the target log data, ensuring the source of the target log data is clearly identifiable. The advantages are twofold: First, it ensures the accurate attribution of the target log data, enabling the cloud server to effectively identify and manage target log data from different home appliances. Second, by registering and assigning codes to home appliances before data upload, log data management efficiency is improved, reducing the risk of log data contamination. Furthermore, it enhances security during log data management, allowing only registered home appliances to upload log data and preventing unauthorized access. Overall, the home appliance registration and coding mechanism described in steps 271 to 272 enables efficient management and use of target log data, improving the overall reliability of log data management and user experience.

[0082] In this application, step 273 may also be performed:

[0083] Step 273: If the network communication channel between the target home appliance and the cloud server is interrupted (for example, the WiFi connection of the target home appliance drops), the target log data is sent to other home appliances so that the other home appliances can upload the target log data to the cloud server.

[0084] In this application, before sending the target log data to other home appliances, the following step 2731 may also be performed:

[0085] Step 2731: Broadcast pairing information via short-range wireless communication so that the other home appliances can establish a short-range wireless communication channel with the target home appliance based on the pairing information.

[0086] In this application, the short-range wireless communication method can be Bluetooth communication. Specifically, as... Figure 1As shown, firstly, the target home appliance (home appliance 101a) enters discoverable mode and broadcasts Bluetooth pairing information. Other home appliances (home appliances 101b and 101c) scan the channel to discover the pairing information. Then, the other home appliances initiate pairing requests, exchanging pairing keys to establish a secure connection with the target home appliance. After successfully pairing with other home appliances, the target home appliance establishes a short-range wireless communication channel B with them for data exchange and transmission. This allows the target home appliance to communicate with other home appliances even when its network is interrupted, enabling them to upload target log data to the cloud server 104.

[0087] Based on the technical solution in step 273 above, when the network communication channel between the target home appliance and the cloud server is interrupted, the target log data can be uploaded to other home appliances by sending the target log data, which can ensure the reliability and integrity of the target log data upload, improve the robustness of the home appliance in saving log data, and thus reduce the risk of log data loss in the home appliance.

[0088] In this application, the step of sending the target log data to other home appliances so that the other home appliances can upload the target log data to the cloud server can be performed according to the following steps 2732 to 2733:

[0089] Step 2732: Send the target device code of the target home appliance to the other home appliances, so that the other home appliances can send the target device code to the cloud server for verification.

[0090] Step 2733: If the target home appliance receives a confirmation message sent by the other home appliance, then the target log data is sent to the other home appliance so that the other home appliance can upload the target log data to the cloud server. The confirmation message is used to indicate that the target device code has passed the verification of the cloud server.

[0091] Based on steps 2732 and 2733 above, before uploading the target log data via other home appliances, the target device code is verified by the cloud server to ensure that only target log data from registered home appliances can be uploaded, thus ensuring the security of the entire log data upload process. Using other home appliances as intermediaries for target log data upload increases the flexibility and stability of data transmission, especially when the target device's network connection is unstable, ensuring log data upload and reducing the risk of log data loss from home appliances.

[0092] In this application, based on step 2733 above, the other household appliances can perform the following step 2734:

[0093] Step 2734: After the other home appliances receive the target log data, the other home appliances add the target device code to the set position of the target log data and upload the target log data to the cloud server, so that the cloud server can identify and save the target log data of the target device based on the target device code.

[0094] In this application, step 2734 offers the advantage of enhancing the accuracy and security of data management. When other home appliances receive the target log data, they add the target device code to the designated location within the target log data, ensuring that the target log data uploaded to the cloud server can be accurately identified and categorized. In this way, the cloud server can effectively identify and store log data based on the target device code, preventing confusion or loss of target log data from different home appliances, thereby improving the efficiency of log data management. Furthermore, it can further verify the legitimacy of the log data source, preventing unauthorized log data uploads and enhancing the security of log data management across all home appliances.
