In order for any person skilled in the art to implement and use the present application, the following description is given. In the following description, details are set forth for the purpose of explanation. It should be understood that those of ordinary skill in the art can recognize that the present application can be implemented without the use of these specific details. In other instances, well-known structures and processes are not described in detail to avoid unnecessary details from obscuring the description of the present application. Therefore, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in the present application.

[0035] The embodiments of the present application provide a data processing method, device, system and related equipment, which will be described in detail below respectively.

[0036] As Figure 1 shown, Figure 1It is a schematic diagram of the scenario of the data processing system provided by an embodiment of the present application. The data processing system may include an embedded device 100 and a host computer 200. The embedded device 100 is connected to the host computer 200. The embedded device includes a processor, and the processor includes a storage area. The storage area includes an application area, a bootloader area, and a fixed address area. The application area stores an application program, and the bootloader area stores a bootloader program;

[0037] The host computer 200 is used to periodically detect whether the embedded device is in an idle state, and when the embedded device is in an idle state, send upgrade data to the embedded device;

[0038] The processor is used to run the application program and determine whether the embedded device meets the startup conditions of the upgrade task; if so, receive the upgrade data for the application program sent by the host computer, and write startup data reflecting the upgrade task in the fixed address area;

[0039] Run the bootloader program and determine whether the embedded device meets the upgrade conditions of the upgrade task; if so, upgrade the application program based on the upgrade data, and write completion data reflecting the upgrade task in the fixed address area after the upgrade is completed;

[0040] Loop to run the application program and the bootloader program until the written startup data and / or completion data meet the criteria for test completion.

[0041] Among them, the host computer 200 generally refers to a computer system used to control or monitor a lower computer (such as the embedded device 100). It can exchange data with the lower computer through various communication protocols (such as serial port, CAN bus, USB, etc.). During the firmware upgrade process, the host computer 200 is responsible for sending upgrade data (including firmware) to the embedded device 100 and ensuring that these firmware are correctly received and executed. The embedded device 100 refers to a dedicated hardware device integrated with an operating system and an application program. They are usually used to perform specific tasks, such as controlling other devices, processing sensor data, etc. In the scenario of firmware upgrade, the embedded device 100 refers to a processor or other type of dedicated hardware device that needs to update its firmware to improve functions or fix known problems.

[0042] In actual operation, the host computer 200 can communicate with the embedded device 100 in a wired or wireless manner to achieve the transmission of firmware.

[0043] Among them, the start condition of the upgrade task is the main judgment basis for whether the embedded device can enter the upgrade process normally. Specifically, the start condition of this upgrade task can be that the processor (Central Processing Unit, CPU) of the embedded device is in an "idle state".

[0044] Specifically, when the processor of the embedded device is in an idle state, it usually means that the processor has no tasks or workloads to process temporarily, so it is in a state of waiting for new tasks to arrive or be executed. In this state, the processor may reduce its working frequency or voltage to reduce power consumption; the processor may stop executing instructions, but still maintain the ability to monitor external events or interrupts. Once there is a new task to process, it will quickly return to the normal working state; the processor may enter a deeper low-power mode (such as sleep mode), in which most of the functions of the processor will pause, and only a few key functions remain active for quick recovery.

[0045] Therefore, when the embedded device 100 is in an idle state, that is, when the embedded device meets the start condition of the upgrade task, the host computer 200 can use this opportunity to send upgrade data to trigger the upgrade task of the embedded device, so as to ensure that the device can perform firmware update without affecting its key functions.

[0046] In addition, the embedded device 100 also has the functions in the data processing method as follows. For specific details, please refer to the following specific embodiments and will not be elaborated here.

[0047] In the embodiment of the present application, the processor runs the application program stored in the application program area and the bootloader stored in the bootloader area in a loop. Specifically, by running the application program to determine whether the embedded device meets the start condition of the upgrade task, and when the start condition of the upgrade task is met, receiving the upgrade data for the application program sent by the host computer, and writing the start data reflecting the upgrade task in the fixed address area; by running the bootloader to determine whether the embedded device meets the upgrade condition of the upgrade task, and when the upgrade condition of the upgrade task is met, upgrading the application program based on the upgrade data, and writing the completion data reflecting the upgrade task in the fixed address area after the upgrade is completed; until the written start data and / or completion data meet the test completion standard, the automatic upgrade test of the embedded device can be realized without manual operation, making full use of the characteristics of the embedded device itself. Therefore, the manual operation link is reduced, the test efficiency is improved, and the test cost is reduced.

[0048] Those skilled in the art can understand, Figure 1The application environment shown is merely one application scenario of the solution of this application, and does not constitute a limitation on the application scenario of the solution of this application. Other application environments may also include more or fewer host computers and / or embedded devices than those shown in Figure 1 For example, there may be more or fewer host computers and / or embedded devices than those shown in Figure 1 Only 1 host computer and embedded device are shown in . It can be understood that this data processing system may also include one or more other embedded devices, which are not specifically limited here.

[0049] It should be noted that Figure 1 The schematic diagram of the data processing system shown is merely an example. The data processing system and scenario described in the embodiments of this application are for more clearly explaining the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided by the embodiments of this application. Those of ordinary skill in the art know that with the evolution of the data processing system and the emergence of new business scenarios, the technical solutions provided by the embodiments of this application are equally applicable to similar technical problems.

[0050] Next, the data processing method provided by the embodiments of this application will be introduced.

[0051] In the embodiments of the data processing method of this application, an embedded processor is used as the execution subject. For the sake of simplicity and convenience of description, the execution subject will be omitted in the subsequent method embodiments. The processor includes a storage area, which includes an application area, a bootloader area, and a fixed address area. Among them, the application area stores an application, and the bootloader area stores a bootloader. The method includes: running the application, and determining whether the embedded device meets the startup conditions of the upgrade task; if so, receiving the upgrade data for the application sent by the host computer, and writing startup data reflecting the upgrade task in the fixed address area; running the bootloader, and determining whether the embedded device meets the upgrade conditions of the upgrade task; if so, upgrading the application based on the upgrade data, and writing completion data reflecting the upgrade task in the fixed address area after the upgrade is completed; running the application and the bootloader in a loop until the written startup data and / or completion data meet the criteria for test completion.

[0052] The data processing method described in this application will be described in detail below with reference to the accompanying drawings. Although the method operations steps provided in this application are as shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on routine or non-creative labor. In steps where there is no necessary causal relationship logically, the execution order of these steps is not limited to the execution order provided in the embodiments of this application. When the method is actually processing objects or executed by a device, it can be executed in the method order shown in the embodiments or drawings or in parallel (such as in an environment of parallel processors or multi-threaded processing).

[0053] Specifically, please refer to Figures 2 to 4 , Figure 2 which is a schematic flowchart of an embodiment of the data processing method provided in the embodiment of this application. Specifically, this data processing method includes steps 201 to 203:

[0054] 201. Run the application program and determine whether the embedded device meets the startup conditions for the upgrade task.

[0055] Among them, the application program refers to program code designed and written to perform specific functions under a specific software and hardware environment. This program code is optimized to utilize the architecture and performance characteristics of the processor to achieve tasks such as efficient data processing and computing operations. Therefore, the application program in the processor can be understood as software running on the processor, and it can include but is not limited to the following types: embedded application programs, where the embedded processor is mainly used to run dedicated programs for specific fields, such as in the fields of mobile phones, DVDs, set-top boxes, etc.

[0056] In one embodiment, when the application program is in a running state, it will determine whether the embedded device meets the startup conditions for the upgrade task. Specifically, in the step of determining whether the embedded device meets the startup conditions for the upgrade task, it can specifically include: determining whether the processor of the embedded device is in an "idle state". If so, it is determined that the embedded device meets the startup conditions for the upgrade task. If not, it is determined that the embedded device does not meet the startup conditions for the upgrade task.

[0057] 202. If so, receive the upgrade data for the application program sent by the host computer and write the startup data reflecting the upgrade task in the fixed address area.

[0058] Among them, the upgrade data may include firmware of the same version to receive the firmware repeatedly sent by the host computer through the processor.

[0059] In addition, the upgrade data may further include multiple copies of firmware of different versions to receive the firmware repeatedly sent by the host computer through the processor. The selection of specific upgrade data can be made according to actual requirements. For example, in order to evaluate the upgradability of an embedded device to a certain version of firmware, the host computer can send the firmware of this version multiple times in sequence so that the embedded device can be upgraded according to the firmware of this version multiple times, thereby evaluating the upgradability of this version. For example, in order to evaluate the upgrade adaptability of an embedded device to firmware of different versions, the host computer can send multiple copies of firmware of different versions in sequence so that the embedded device can be upgraded according to the firmware of different versions multiple times, thus evaluating the upgrade adaptability of the embedded device to different firmware.

[0060] The process of writing the start data reflecting the upgrade task in the fixed address area refers to the process of increasing the start times in the fixed address area. For example, if it is the first upgrade task currently, then the start times in the fixed address area change from 0 to 1, that is, the process of +1.

[0061] In some embodiments, the storage area further includes an upgrade area; the step of receiving the upgrade data for the application program sent by the host computer and writing the start data reflecting the upgrade task in the fixed address area specifically includes: when receiving the upgrade data, writing the upgrade data into the upgrade area; if the upgrade data is successfully written into the upgrade area, then writing the start data reflecting the upgrade task in the fixed address area.

[0062] It can be understood that for the start data +1, it only needs to start receiving the upgrade data for the application program sent by the host computer. Regarding whether the subsequent upgrade is successful or not, it will not affect the start data +1.

[0063] In a specific embodiment, when the processor of the embedded device receives the upgrade data and successfully writes the upgrade data into the upgrade area, then write the start data reflecting the upgrade task in the fixed address area, that is, +1 on the basis of the original start data. For example, the original start data is 100, and the updated start data is 101.

[0064] 203. Run the bootloader and determine whether the embedded device meets the upgrade conditions of the upgrade task.

[0065] Among them, the bootloader runs earliest after the embedded device hardware is powered on or restarted, and is responsible for starting and managing the software and hardware environment of the system to prepare the correct environment for finally calling the operating system kernel.

[0066] In addition, the bootloader in an embedded device can also have the following functions: Initialize hardware: The bootloader first needs to complete the initialization of the processor and related hardware. This includes setting the clock frequency, configuring the memory mapping, initializing peripherals, etc. Load the operating system: The bootloader reads the operating system kernel from a storage medium (such as a solid-state drive) into RAM and jumps to the entry point of the kernel to start the operating system. Intermediate role: The bootloader acts as an intermediary between the hardware and the operating system to ensure a smooth handover between the two.

[0067] In some embodiments, in the step of determining whether the embedded device meets the upgrade conditions for the upgrade task, it may specifically include: determining whether the upgrade data is stored in the upgrade area. If the upgrade data is stored in the upgrade area, it is determined that the embedded device meets the upgrade conditions for the upgrade task. If the upgrade data is not stored in the upgrade area, it is determined that the embedded device does not meet the upgrade conditions for the upgrade task.

[0068] 204. If so, upgrade the application program based on the upgrade data, and write the completion data reflecting the upgrade task in the fixed address area after the upgrade is completed.

[0069] Among them, the step of upgrading the application program based on the upgrade data and writing the completion data reflecting the upgrade task in the fixed address area after the upgrade is completed specifically includes: erasing the original application program and migrating the upgrade data to the application program area; if the upgrade data is successfully migrated to the application program area, write the completion data reflecting the upgrade task in the fixed address area after the upgrade is completed.

[0070] In a specific embodiment, the processor erases the original application program stored in the application program area and migrates the upgrade data from the upgrade area to the application program area; if the upgrade data is successfully migrated to the application program area, write the completion data reflecting the upgrade task in the fixed address area after the upgrade is completed.

[0071] Specifically, writing the completion data reflecting the upgrade task in the fixed address area can be understood as the processor adding 1 to the original number of completion times to obtain the updated completion data.

[0072] For example, if the original number of completion times is 100 times, the updated number of completion times is 101 times.

[0073] 205. Run the application program and the bootloader in a loop until the written startup data and / or completion data meet the test completion standard.

[0074] Among them, the standard for completing the test can be the requirement for the number of times of startup data, and the specific value of the number of times can be set according to the actual needs of the test, which is not limited here. For example, the standard for completing the test can be set such that the number of times of startup data needs to reach 10 times, 100 times, 200 times, 500 times, and 1000 times.

[0075] Optionally, the standard for completing the test can be the requirement for the number of times of completion data, and the specific value of the number of times can be set according to the actual needs of the test, which is not limited here. For example, the standard for completing the test can be set such that the number of times of completion data needs to reach 10 times, 100 times, 200 times, 500 times, and 1000 times.

[0076] Optionally, the standard for completing the test can be the requirement for the number of times of both startup data and completion data, and the specific value of the number of times can be set according to the actual needs of the test, which is not limited here. For example, the standard for completing the test can be set as follows: the number of startup times needs to reach or exceed 10 times, and at the same time, the completion data needs to reach at least 6 times; or, the number of startup times needs to reach or exceed 100 times, and at the same time, the completion data needs to reach at least 60 times; or, the number of startup times needs to reach or exceed 200 times, and at the same time, the number of completion times needs to reach at least 120 times; or, the number of startup times needs to reach or exceed 500 times, and at the same time, the number of completion times needs to reach at least 300 times; or, the number of startup times needs to reach or exceed 1000 times, and at the same time, the number of completion times needs to reach at least 600 times.

[0077] When the written startup data and / or the completion data meet the standard for completing the test, the loop operation of the application program and the bootloader can be stopped.

[0078] In the embodiment of the present application, the application program stored in the application program area and the bootloader stored in the bootloader area are cyclically run by the processor. Specifically, by running the application program to determine whether the embedded device meets the startup conditions of the upgrade task, and when the startup conditions of the upgrade task are met, receiving the upgrade data of the application program sent by the host computer, and writing the startup data reflecting the upgrade task in the fixed address area; by running the bootloader to determine whether the embedded device meets the upgrade conditions of the upgrade task, and when the upgrade conditions of the upgrade task are met, upgrading the application program based on the upgrade data, and writing the completion data reflecting the upgrade task in the fixed address area after the upgrade is completed; until the written startup data and / or completion data meet the standard for completing the test, the automated upgrade test of the embedded device can be realized without manual operation, making full use of the characteristics of the embedded device itself. Therefore, the manual operation link is reduced, the test efficiency is improved, and the test cost is reduced.

[0079] After the test is completed, when testers need to view the parameters in the upgrade test, it can be achieved in the following ways.

[0080] In some embodiments, the test data can be presented in a passive manner, which specifically includes: after the test is completed, receiving the query instruction sent by the host computer; reading the start data and the completion data from the fixed address area.

[0081] In the embodiment of the present application, through the communication between the host computer and the embedded device, the start data and the completion data stored in the fixed address area after the test is completed can be queried by the host computer, improving the convenience of obtaining test data.

[0082] Further, the test data that needs to be calculated can also be presented in an active manner, which specifically includes: after the test is completed, obtaining the start data and the completion data from the fixed address area; calculating the upgrade success rate of the upgrade data according to the start data and the completion data; uploading the upgrade success rate of the upgrade data to the host computer.

[0083] In the embodiment of the present application, through the communication between the host computer and the embedded device, the embedded device can actively present the required upgrade success rate, further improving the convenience of obtaining test data.

[0084] In some embodiments, the step of calculating the upgrade success rate of the upgrade data according to the start data and the completion data may specifically include: comparing the completion data with the start data to obtain the upgrade success rate. For example, let the upgrade success rate be a, then a = (b / c) * 100%, where b is the completion data (i.e., the number of successful upgrades), and c is the start data (i.e., the number of upgrade starts).

[0085] During the entire upgrade test process, there may be exceptions, and how to automatically analyze the reasons for the exceptions can effectively improve the upgrade test efficiency and reduce the test cost. Specifically, the following methods can be adopted.

[0086] In some embodiments, after the step of calculating the upgrade success rate of the upgrade data according to the start data and the completion data, the method may further include: steps 206 to 207:

[0087] 206. Determine whether there is an exception during the upgrade process of the embedded device according to the upgrade success rate and a preset upgrade success rate threshold;

[0088] In one embodiment, if the upgrade success rate is lower than a preset upgrade success rate threshold, it is determined that there is an abnormality in the upgrade process of the embedded device within the preset time period. If the upgrade success rate is not lower than the preset upgrade success rate threshold, it is determined that the upgrade process of the embedded device within the preset time period is normal.

[0089] Among them, the preset upgrade success rate threshold can be set according to actual needs. For example, the upgrade success rate threshold can be set to 50%, 60%, 70%, 80%, 85%, 90%.

[0090] In a specific embodiment, when the target upgrade success rate (70%) is lower than the preset upgrade success rate threshold (85%), it is determined that there is an abnormality in the upgrade process of the embedded device within the preset time period.

[0091] 207. If so, obtain the device information, upgrade process information, and the upgrade data of relevant devices during the upgrade process within the preset time period, and based on the device information, the upgrade process information, and the upgrade data, determine the abnormal analysis data that causes the abnormality in the upgrade process.

[0092] The upgrade process of the embedded device involves multiple key components and technologies, including the processor, Bootloader, network connection, user interface, security mechanism, and differential upgrade technology. These components and technologies together ensure that the embedded device can perform remote software updates stably and efficiently.

[0093] Optionally, the step of determining the abnormal analysis data that causes the abnormality in the upgrade process based on the device information, the upgrade process information, and the upgrade data includes: extracting upgrade abnormal feature data from the device information, the upgrade process information, and the upgrade data; inputting the upgrade abnormal feature data into a pre-trained network prediction model for upgrade abnormal analysis to obtain a model prediction result; and based on the model prediction result, determining the abnormal analysis data that causes the abnormality in the upgrade process.

[0094] Specifically, extracting the upgrade abnormal feature data from the device information, the upgrade process information, and the upgrade data can be specifically implemented in the following ways:

[0095] First, it is necessary to collect and preprocess the operation data of the device. This includes steps such as data cleaning, filling missing values, standardization, and normalization to ensure data quality.

[0096] Before performing anomaly detection, it is necessary to extract useful features from the original data. These features can help better describe the state and behavior of the device. Common feature extraction methods include algorithms based on manual construction, self-supervised learning methods, and various transformation methods. For example, methods such as Fourier transform and wavelet transform can be used to extract features from signals, thereby obtaining a large number of features.

[0097] The relationship between different features and the recognition rate can be analyzed to select those features that are most important for anomaly detection. In addition, automatic multivariable closed-loop identification technology can be used to improve the identification efficiency and quality of the model.

[0098] Using the extracted and optimized features, train traditional supervised machine learning models or deep learning models to extract features from the device to be recognized and determine whether there is an anomaly based on the model output. Analyze on the feature data and output whether the monitored object is abnormal. If an anomaly is detected, fault warning can be further combined with historical annotation information and prior information.

[0099] During the closed-loop control process of the prediction model, the model can be continuously updated to adapt to changes in the device operating environment. This helps to improve the accuracy and robustness of the model.

[0100] Finally, combine the extracted anomaly feature data with model prediction technology to continuously predict future device operations under the current operating data, compare the predicted values with the set target values, and finally calculate new control actions to reduce the fluctuations of key variables in the process and operate the device in the best state.
