Description

Technical Field

[0001] This application relates to the technical field of data storage, and particularly to a multi-master data storage and interaction method, device, equipment, and medium. Background Art

[0002] In modern electronic devices and embedded systems, the microcontroller unit is a core component, and its performance and storage capacity are crucial to the device functions. Due to cost and resource limitations during design, many low-cost microcontroller units have obvious technical bottlenecks in data storage and interaction. On the one hand, the data storage limitations are significant. The memory is small, making it difficult to meet the growing data storage requirements. When processing complex data, data loss or overwriting is likely to occur, affecting the system stability and reliability. On the other hand, the code volume is limited, and the memory and computing power are insufficient, resulting in difficulties for developers to add complex error handling mechanisms or data backup schemes. The code storage space is scarce, and it is difficult to implement efficient data processing and management strategies. In addition, low-cost microcontroller units lack a data double-backup mechanism. In case of anomalies (such as power failures, hardware errors, etc.), the stored data may not be recoverable, leading to irreversible data loss, directly affecting the device functions, usage value, and reliability. With the popularization of smart devices and the expansion of application fields, the market has put forward higher requirements for the data storage and interaction capabilities of microcontroller units. The reliability of the existing storage and interaction technologies of low-cost microcontroller units is insufficient to adapt to this trend, restricting their promotion and application in high-performance application fields.

[0045] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0046] In order to better understand the technical solutions of the present application, the following will be described in detail with reference to the accompanying drawings of the specification and specific embodiments.

[0047] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device, a terminal system, etc. that can implement the above functions. The following takes the system as an example to illustrate this embodiment and the following embodiments.

[0048] Based on this, this embodiment provides a multi-master data storage and interaction method, referring to Figure 1 , Figure 1 It is a schematic flowchart of the multi-master data storage and interaction method of the present application. The multi-master data storage and interaction method includes steps S10 to S30:

[0049] Step S10, read the configuration check values corresponding to multiple storage areas in the preset first master processor;

[0050] Step S20, check whether the storage check values in each storage area are consistent with the corresponding configuration check values to obtain the corresponding check results;

[0051] Step S30, determine the valid data according to the check results of each storage area, update the valid data to the corresponding storage area, and update the valid data to the global configuration array of the preset first master processor. Each storage area includes a main storage area and a backup storage area, and the first master processor is communicatively connected to the second master processor.

[0052] It should be noted that in this embodiment, the first main control processor refers to one of the main processor units in the system. It contains multiple storage areas, and each storage area is preset with a configuration verification value for verifying the integrity of the stored data. These configuration verification values are set for each storage area during the initialization phase to ensure that the data has not been tampered with or damaged. The storage verification value is a value calculated by a specific algorithm based on the actual data stored in the storage area and is used to compare with the configuration verification value to determine the validity of the data. The second main control processor is another processor unit responsible for receiving the valid data from the first main control processor. If the second main control processor needs to update the configuration data, it can be synchronized to the global configuration array of the first main control through the connection with the first main control. The global configuration array is a place where system parameters are centrally stored and allows external applications to read the data therein.

[0053] First, when the system is powered on, the first main control processor reads the preset configuration verification values from its multiple storage areas. These storage areas include the main storage area and the backup storage area, and each storage area has a storage verification value calculated based on its internal data. Next, for each storage area, the system checks whether the storage verification value matches the preset configuration verification value. This process compares the two values through a preset comparison algorithm to obtain the verification result. If the two are consistent, the data in that storage area is considered valid; otherwise, there may be problems. Subsequently, the system determines which data is valid based on the verification results of each storage area and updates these valid data to the global configuration array of the first main control processor. If status synchronization is required, it can be synchronized to the second main control processor through a serial port connection at this time, and the valid data is also updated to the corresponding storage area. For example, the valid data obtained from the main storage area is updated to the backup storage area, and the valid data obtained from the backup storage area is updated to the main storage area.

[0054] Exemplarily, referring to Figure 2 , Figure 2This is the implementation flowchart of the multi-master data storage and interaction method of this application. The user operates through the host computer on the PC (Personal Computer) side, clicks the corresponding function button, and sends a status setting instruction to the device. The request is transmitted to the first master processor at the device end through USB (Universal Serial Bus) connection. Ensure that the USB connection is normal to ensure the accurate transmission of data requests. After receiving the configuration request, the first master processor updates the global configuration array in the first master and forwards the request to the second master processor through the serial port as needed. The serial communication method effectively guarantees the reliable transmission of data. The first master processor parses the received request and stores the specified data in its internal storage area in a double-backup manner according to the processing logic of this embodiment. After the storage is completed, the first master processor returns the stored data to the second master processor for further processing through the serial port as needed to ensure the integrity of the data during the transmission process. The first master processor uses the private stream protocol to transmit the data to the PC-side host computer software being monitored.

[0055] Exemplarily, referring to Figure 3 , when performing a write operation, the system will obtain the configuration items of the first master processor and perform processing of writing to the main storage area and the backup storage area in the data storage module according to the content of the configuration items. Referring to Figure 4 , when performing a read operation, the system will obtain the configuration items of the first master processor and perform processing of reading the global configuration array in the data storage module according to the content of the configuration items.

[0056] This embodiment can be further optimized by introducing a real-time monitoring mechanism to dynamically adjust the verification frequency of the storage area, especially increasing the verification times before and after performing critical tasks to ensure the security and reliability of the data. For example, in an industrial automation scenario, when the device is about to perform an important operation, automatically increase the data verification frequency to ensure the integrity and accuracy of the data during the operation. In addition, machine learning algorithms can be used to analyze historical verification results, predict possible problems, and take measures in advance to avoid data loss. This method not only enhances the adaptability of the system but also improves the flexibility and response speed of data processing.

[0057] This embodiment reads the configuration verification values corresponding to multiple storage areas in a preset first main control processor; through this operation, a benchmark can be provided for subsequent data verification to ensure the accuracy and integrity of the data; it checks whether the storage verification values in each storage area are consistent with the corresponding configuration verification values to obtain the corresponding verification results; this process can effectively identify whether there are errors or losses in the data in the storage area to ensure the reliability of the data; based on the verification results of each storage area, valid data is determined, updated to the corresponding storage area, and the valid data is updated to the global configuration array of the preset first main control processor. Among them, each storage area includes a main storage area and a backup storage area, and the first main control processor is communicatively connected to the second main control processor; this series of operations can not only ensure the consistency and synchronization of data between different storage areas, but also improve the security and fault tolerance of the data through the backup storage area. At the same time, it simplifies the data management process, reduces the development cost and labor cost, improves the overall performance and stability of the system, effectively solves the technical bottleneck problems of low-cost microcontroller units in data storage and interaction, better meets the requirements of complex application scenarios for data storage and interaction, and improves the reliability of low-cost microcontroller units in data storage and interaction.

[0058] Based on Embodiment 1 of the present application, in Embodiment 2 of the present application, the same or similar content as that in the above Embodiment 1 can be referred to the above introduction and will not be elaborated hereinafter. On this basis, the steps of Step S20 further include steps A11 to A12:

[0059] Step A11, if the storage verification value in the storage area is consistent with the corresponding configuration verification value, then determine whether there is a newly added saved configuration item in the operation area of the first main control processor;

[0060] Step A12, if there is a newly added saved configuration item in the operation area, then update the default value of the saved configuration item to the storage area and confirm that the verification result of the storage area is a successful verification.

[0061] It should be noted that in this embodiment, the storage verification value is a value corresponding to the data actually saved in the storage area, which is used to compare with the configuration verification value calculated by a certain agreed rule for the preset configuration item to determine the validity of the data. The configuration verification value is a value set for each storage area in the initialization stage to ensure that the data has not been tampered with or damaged. The newly added saved configuration item refers to the new configuration items added by the user or the system according to needs during the operation of the system, and these configuration items usually have default values. If the storage verification value is consistent with the configuration verification value, it indicates that the data in the storage area has not been damaged, and it can be further checked whether there are new configuration items that need to be updated.

[0062] The system checks whether the stored verification value in the storage area is consistent with the configured verification value. This process is completed by comparing the two values through a specific algorithm to obtain the verification result. If the two are consistent, the data in the storage area is considered valid and not tampered with. Next, the system determines whether there are new saved configuration items in the operating area of the first master processor. If there are new configuration items, the system updates the default values of these configuration items to the storage area and confirms that the verification result of the storage area is successful. For example, in the initialization stage, the global configuration array a and the backup parameter array b have been set up. When new configuration items are detected, the system writes the default values of these configuration items into the corresponding arrays to ensure that the latest state of the system is saved. This process not only ensures the integrity and consistency of the data but also enables the system to adapt to changing requirements.

[0063] Furthermore, this embodiment can be optimized by introducing an intelligent prediction mechanism. Using historical data and machine learning algorithms to analyze which configuration items are more likely to be frequently modified or added, and preparing the corresponding default values in advance to improve the response speed and efficiency of the system. For example, in a smart home scenario, when the device recognizes that the user is accustomed to adding new sensor configurations, the system can pre-load the relevant default configuration items to reduce the real-time processing time. In addition, distributed storage technology can also be considered to disperse the configuration items across multiple nodes to enhance the fault tolerance and data security of the system.

[0064] This embodiment ensures the validity and integrity of the data by checking the consistency between the stored verification value and the configured verification value in the storage area. On this basis, it further checks and updates the newly added saved configuration items, enabling the system to dynamically adapt to new requirements and improving flexibility and response speed.

[0065] In a feasible implementation manner, the steps of step S20 further include step A21:

[0066] Step A21, if the stored verification value in the storage area is inconsistent with the corresponding configured verification value, determine that the verification result of the storage area is a verification failure.

[0067] It should be noted that when the stored verification value is inconsistent with the configured verification value, it indicates that there may be problems with the data in the storage area, such as data loss, damage, or illegal modification.

[0068] First, the system calculates the storage check value of the data in the storage area and compares it with the preset configuration check value. If the two values do not match, the system determines that the check result of the storage area is a failure. This means that the data in the storage area may have been damaged or unauthorized changes have occurred. For example, during the data synchronization process of the first main control processor, if the storage check value of a certain storage area fails to match the configuration check value, it indicates that there may be data anomalies or other problems. At this time, the system will not use the data in this storage area for any further operations, but mark this area as a check failure state. This step is crucial for ensuring the stability of the system and the reliability of the data, as it can prevent system failures or incorrect results caused by using unreliable or damaged data.

[0069] This embodiment can be further optimized by introducing intelligent data analysis technology. Using historical check data, the system can predict which storage areas are more likely to have check failures and take preventive measures in advance, such as increasing redundant backups or adjusting the data update strategy. For example, in an industrial automation environment, the data of certain key sensors needs to be highly reliable. The system can perform additional checks and backups on this data to ensure that the production process is not affected even in case of unexpected situations. In addition, by adopting distributed storage and multi-path transmission technologies, the security and stability of data transmission can be enhanced, reducing data check failures caused by single-point failures.

[0070] Through the consistency check of the storage check value and the configuration check value in the storage area, this embodiment can timely detect and mark the problematic data storage areas, avoiding the risk of using unreliable data. This method significantly improves the stability of the system and the reliability of the data, reducing system failures caused by data damage or loss.

[0071] Based on Embodiment 1 or Embodiment 2 of the present application, in Embodiment 3 of the present application, the same or similar content as that in Embodiment 1 or Embodiment 2 above can be referred to the above introduction and will not be elaborated hereinafter. The steps of Step S30 further include steps B11 to B12:

[0072] Step B11, if the check result of the main storage area is successful and the check result of the backup storage area is a failure, then determine the data in the main storage area as valid data;

[0073] Step B12, update the backup storage area according to the valid data.

[0074] It should be noted that if the check result of the main storage area shows success while the check result of the backup storage area shows failure, it is considered that the data in the main storage area is valid, and these valid data need to be updated to the backup storage area and the global configuration array to ensure data consistency and integrity.

[0075] The system checks the verification results of the primary storage area and the backup storage area. If the verification result of the primary storage area is successful, it indicates that the data in this area is intact and can be trusted. On the contrary, if the verification result of the backup storage area is failed, it means that the backup data may be damaged or there are errors. In this case, the system determines the data in the primary storage area as valid data. Next, the system performs a data update operation to synchronize this valid data to the backup storage area to ensure that the backup data is repaired and updated. At the same time, this valid data will also be written into the global configuration array of the first master processor so that external applications can obtain the latest and reliable data by accessing the global configuration array.

[0076] Furthermore, this embodiment can be further optimized by introducing an automatic data repair mechanism. When it is detected that the verification of the backup storage area fails, not only the data is updated, but also the cause of the verification failure can be analyzed, and measures can be taken to prevent similar problems from occurring again. In addition, the distributed ledger technology is adopted to record each data update and verification situation, enhancing data transparency and traceability.

[0077] This embodiment effectively identifies the valid data by comparing the verification results of the primary storage area and the backup storage area, and updates it to the backup storage area and the global configuration array in a timely manner, ensuring data consistency and integrity. By utilizing the dual-backup mechanism, the stability of the system and the security of the data are enhanced.

[0078] In a feasible implementation manner, the steps of step S30 further include steps B21 to B22:

[0079] Step B21, if the verification result of the primary storage area is failed and the verification result of the backup storage area is successful, then determine the data in the backup storage area as valid data;

[0080] Step B22, update the primary storage area according to the valid data.

[0081] It should be noted that in this embodiment, if the verification result of the primary storage area shows failure while the verification result of the backup storage area shows success, it is considered that the data in the backup storage area is valid, and these valid data need to be updated to the primary storage area and the global configuration array to ensure data consistency and integrity.

[0082] If the verification result of the main storage area fails, it indicates that the data in this area may be incorrect or have been tampered with; while the verification result of the backup storage area is successful, it indicates that the backup data is intact and can be trusted. In this case, the system will confirm the data in the backup storage area as valid data. Next, the system performs a data update operation to synchronize this valid data to the main storage area to repair possible data problems. At the same time, this valid data will also be written into the global configuration array of the first main control processor so that external applications can access the latest and reliable data. This process utilizes a dual-backup mechanism to ensure that even when a problem occurs in one storage area, it can be quickly restored and data consistency can be maintained.

[0083] In this embodiment, by comparing the verification results of the main storage area and the backup storage area, valid data is effectively identified and updated to the main storage area and the global configuration array in a timely manner, ensuring data consistency and integrity.

[0084] In a feasible implementation manner, the multi-main-control data storage and interaction method further includes steps B31 to B32:

[0085] Step B31, if the verification result of the main storage area fails and the verification result of the backup storage area fails, then determine the preset global default data as valid data;

[0086] Step B32, update the valid data to the global configuration array.

[0087] It should be noted that the global default data is a set of standard data preset during system initialization and is used as a safety net for the system when the data in all storage areas is unavailable. If the verification results of both the main storage area and the backup storage area fail, it is considered that the data in both these storage areas has problems, and at this time, the global default data needs to be used as valid data.

[0088] The system will verify the main storage area and the backup storage area, calculate their respective storage verification values and compare them with the preset configuration verification values. If both verification results fail, it indicates that the data in these two storage areas may be incorrect or have been tampered with. In this case, the system will confirm the preset global default data as valid data. These global default data are usually set during the system initialization phase and stored in the global configuration array. Next, the system performs a data update operation to write this valid data into the global configuration array to ensure that even when the data in both the main storage area and the backup storage area is unavailable, the system can still operate normally and provide services.

[0089] Furthermore, this embodiment can be optimized by introducing a dynamic data recovery mechanism. When it is detected that all storage area verifications fail, not only the global default data is used, but also an optimal alternative data set can be automatically generated in combination with historical data and user habits. In addition, the distributed storage technology is adopted to disperse the key data among multiple nodes, enhancing the fault tolerance and data security of the system and reducing the risk brought by single point of failure.

[0090] This embodiment utilizes the preset default data to ensure that the system still has basic functions in extreme cases and avoids complete system failure due to data loss.

[0091] In a feasible implementation manner, the steps of step S30 further include steps B41 to B43:

[0092] Step B41, if the verification result of the main storage area is successful and the verification result of the backup storage area is successful, then verify whether the storage verification value of the main storage area is consistent with the storage verification value of the backup storage area;

[0093] Step B42, if the storage verification value of the main storage area is consistent with the storage verification value of the backup storage area, then determine the data in the main storage area as valid data and update the valid data to the global configuration array;

[0094] Step B43, if the storage verification value of the main storage area is inconsistent with the storage verification value of the backup storage area, then determine the data in the main storage area as valid data and update the backup storage area according to the valid data.

[0095] It should be noted that if the verification results of both the main storage area and the backup storage area are successful, then further check whether the storage verification values of these two storage areas are consistent to ensure that the data completely matches. If the two are consistent, then confirm the data in the main storage area as valid data; if they are inconsistent, still use the data in the main storage area as the standard and perform necessary update operations.

[0096] If the verification results of both are successful, it indicates that the data in both storage areas is intact. Next, the system will further compare the storage verification values of the main storage area and the backup storage area. If these two storage verification values are consistent, it means that the data in the main storage area and the backup storage area is exactly the same. At this time, the data in the main storage area is confirmed as valid data and these valid data are updated to the global configuration array. If the storage verification values are inconsistent, although the verification results of both storage areas are successful, in order to ensure data consistency, the system still regards the data in the main storage area as valid data and updates it to the global configuration array and the backup storage area to repair possible differences. This process ensures data consistency and reliability and prevents problems caused by data asynchronization.

[0097] Furthermore, this embodiment can be optimized by introducing an intelligent synchronization mechanism. When detecting inconsistent storage check values, not only update the data, but also analyze the reasons for the differences and take preventive measures to avoid similar situations from occurring again.

[0098] By comparing the verification results of the main storage area and the backup storage area and the storage check values, this embodiment effectively identifies valid data and updates it to the global configuration array and the backup storage area in a timely manner, ensuring data consistency and integrity, reducing the risks brought by data inconsistency, and improving user experience and trust.

[0099] Exemplarily, referring to Figure 5 , Figure 5 is the full flow chart of this application. After the device is started, operations are performed on the main storage area and the backup storage area simultaneously. Read the configuration check value of the main storage area in the preset first main control processor. Read the configuration check value of the backup storage area in the preset first main control processor. For each storage area, check whether the storage check value in the storage area is consistent with the corresponding configuration check value to obtain a verification result. If the configuration check value is inconsistent with the storage check value, the verification fails directly. If they are consistent, determine whether there are new saved configuration items. If there are new saved configuration items, update the saved configuration items to the storage area and continue the verification. If there are no new saved configuration items, determine that the verification is successful.

[0100] If the verifications of both the main storage area and the backup storage area fail, update the global default array to the global configuration array. If only one storage area verification fails, update the data of that storage area as valid data to the global configuration array and the other storage area.

If they are consistent, determine the data in the main storage area as valid data and update it to the global configuration array. If they are inconsistent, determine the data in the main storage area as valid data and update it to the global configuration array and the backup storage area.
