Description

[0002] With the rapid development of computer technology, historical records are essential functions in many power electronic system products, which can record the past running information of local systems, such as historical fault information, historical power generation data, etc. These information records can be viewed by users, used for tracing system running state and system defects, and statistical data, providing evidence for system operation anomalies, and providing necessary reference for product defect troubleshooting and function upgrade.

[0003] However, in the process of embedded system software design, the storage of historical record information usually adopts a queue data structure to store in a circular manner.

After local display or information export, all historical record information needs to be re-sequenced or relatively complex retrieval calculation needs to be performed, thereby reducing the data export efficiency.

[0029] Embodiment one

[0030] Figure 1 A flowchart of a data storage method applied to an embedded system is provided for an embodiment of the present application. After obtaining instruction information, the embodiment can determine a target storage container corresponding to the instruction information, determine a data storage mode according to data capacity information of the target storage container and a current data capacity, and then realize data storage. The method can be executed by a data storage device applied to an embedded system. The data storage device applied to an embedded system can be realized in the form of hardware and / or software. The device can be configured in an electronic device, which can be a PC or a server, etc.

[0031] As shown in Figure 1 , the method comprises:

[0032] S110, obtaining to-be-applied instruction information, and determining whether the to-be-applied instruction information matches preset instruction information.

[0033] The to-be-applied instruction information can be instruction information generated when data needs to be processed. The preset instruction information can be understood as instruction information that is set in advance for identifying the to-be-applied instruction information.

[0034] Specifically, if the current data needs to be processed, to-be-applied instruction information corresponding to the current data is obtained, and whether the to-be-applied instruction information meets a preset condition is determined according to the preset instruction information. For example, the to-be-applied instruction information and the preset instruction information can be matched, a matching result is obtained, and then whether the to-be-applied instruction information matches the preset instruction information is determined based on the matching result.

[0035] On the basis of the above technical solutions, the determining whether the to-be-applied instruction information matches the preset instruction information comprises: acquiring instruction type information of the to-be-applied instruction information; and determining whether the to-be-applied instruction information matches the preset instruction information based on the instruction type information.

[0036] The instruction type information can be a data processing type of the current to-be-applied instruction information. Correspondingly, the instruction type information comprises at least one of a data storage type, a data export type, and a data zeroing type. The data storage type can be understood as storing data corresponding to the current to-be-applied instruction information. The data export type can be exporting historical data in a storage container. The data zeroing can be understood as deleting data in the storage container.

[0037] Specifically, the instruction type information is extracted from the to-be-applied instruction information, and then it is determined whether the to-be-applied instruction information matches the preset instruction information based on the instruction type information. For example, the preset instruction information can be instruction information of the data storage type, and then it is determined that the current to-be-applied instruction information matches the preset instruction information when the to-be-applied instruction information needs to perform a data storage operation.

[0038] S120, if the to-be-applied instruction information matches the preset instruction information, determining a target storage container corresponding to the to-be-applied instruction information, and acquiring data capacity information and a current data capacity corresponding to the target storage container.

[0039] The target storage container can be a container that needs to perform data storage, for example, a pre-set stack, a queue, and the like. It should be noted that the target storage container comprises a pre-set valve stack, as shown in Figure 2 The valve stack is a kind of "stack" data storage structure, which is open at the top and closed at the bottom, but has a "valve" at the bottom. The data capacity information can be the maximum data capacity information pre-set when the target storage container is set. The current data capacity can be understood as the number of currently stored data in the target storage container.

[0040] Specifically, if the to-be-applied instruction information matches the preset instruction information, the corresponding target storage container is determined based on the to-be-applied instruction information. For example, address information associated with the target storage container can be extracted from the to-be-applied instruction information, and then the target storage container is determined based on the address information. Then, after the target storage container is determined, the data capacity information and the current data capacity corresponding to the target storage container are acquired.

[0041] On the basis of the above technical solutions, the data capacity information corresponding to the target storage container and the current data capacity are acquired, including: acquiring the data capacity information of the target storage container; and determining the current data capacity corresponding to the target storage container based on the push-in counter of the target storage container.

[0042] The data capacity information is a pre-set data storage quantity. The push-in counter can be a timer for counting the quantity of data pushed in.

[0043] Specifically, a designer can abstractly construct a "valve stack" data storage structure according to product function requirements and actual storage resource conditions, and pre-set the storage space depth and content composition of the "valve stack" data storage structure. When initializing the "valve stack" data storage structure, the values of the "push-in counter SP" and the "push-out counter SP" are both set to zero, and the entire "valve stack" data storage container is cleared. Then, when data needs to be stored, the data capacity information of the target storage container can be acquired, and the current data capacity corresponding to the target storage container can be determined based on the push-in counter of the target storage container.

[0044] S130, determining a data storage mode based on the data capacity information and the current data capacity, and storing data based on the data storage mode.

[0045] The data storage mode can be a mode of storing current data.

[0046] Specifically, the data storage mode can be determined based on the data capacity information and the current data capacity, and data can be stored based on the data storage mode. For example, a corresponding data storage mode can be pre-set, and a corresponding index information table can be set, so that the data storage mode can be determined in the index information table based on the data capacity information and the current data capacity, and data can be stored based on the data storage mode.

[0047] On the basis of the above technical solutions, the data storage mode corresponding to the data capacity information and the current data capacity is determined based on the data capacity information and the current data capacity, and data is stored based on the data storage mode, including: if the current data capacity is less than the data capacity information, determining that the data storage mode is direct storage; acquiring the to-be-stored data corresponding to the to-be-applied instruction information, directly storing the to-be-stored data into the target storage container, and updating the current data capacity.

[0048] The direct storage can be directly storing the to-be-stored data into the target storage container. The to-be-stored data can be understood as data corresponding to the to-be-applied instruction information.

[0049] Specifically, if the current data capacity is less than the data capacity information, it is determined that the data storage mode is direct storage, and then the data to be stored corresponding to the to-be-applied instruction information is obtained, the data to be stored is directly stored into the target storage container, and the current data capacity is updated. For example, when a new historical record information is generated, the historical record information needs to be stored in the "valve stack" data storage structure, the "stacking" operation (i.e. "write" operation) is performed, the "stacking counter SP" value is increased by 1 for each historical record information, and the "stacking counter SP" value remains unchanged after the data storage structure is full.

[0050] On the basis of the above technical solutions, the data storage mode corresponding to the data capacity information and the current data capacity is determined, and data storage is performed based on the data storage mode, including: if the current data capacity is greater than or equal to the data capacity information, it is determined that the data storage mode is translation storage; the historical data at the bottom of the target storage container is deleted, and the remaining data information in the target storage container is translated to the bottom of the container in turn; the data to be stored corresponding to the to-be-applied instruction information is obtained, and the data to be stored is stored into the target storage container.

[0051] In the translation storage, after the last day data in the target storage container is deleted, the remaining data is translated downward, and then the data is stored into the target storage container. The historical data can be understood as the data that has been stored into the target storage container.

[0052] Specifically, if the current data capacity is greater than or equal to the data capacity information, it means that the current target storage container is full, and the data in the target storage container needs to be processed to complete the data storage, so the data storage mode is determined to be translation storage. Then the historical data at the bottom of the target storage container needs to be deleted, and the remaining data information in the target storage container needs to be translated to the bottom of the container in turn. Finally, the data to be stored corresponding to the to-be-applied instruction information is obtained, and the data to be stored is stored into the target storage container. It should be noted that, as shown in the figure, since the space depth (size) of the "valve stack" data storage structure is fixed and has been set in advance, when the number of historical record information reaches the pre-set storage space capacity, the "valve" at the bottom of the "valve stack" data storage structure is used to delete or cover the earliest historical record information in it through the "valve", and then the data information in the "valve stack" data storage structure is translated to the bottom of the stack in turn, and finally the newly generated historical record information is stored in the storage space. Figure 3

[0053] ​On the basis of the above technical solutions, the method further comprises: if the to-be-applied instruction information is of a data export type, performing a data export operation based on a stack-out counter and updating stack-out record information of the stack-out counter in real time; and if historical data in the target storage container has been completely exported, setting the stack-out record information of the stack-out counter to a preset value.

[0054] The stack-out counter can be a counter preset for counting the amount of exported data. The stack-out record information can be understood as the record of the stack-out counter updated in real time.

[0055] Specifically, if the to-be-applied instruction information is of a data export type, a data export operation is performed based on a stack-out counter, and stack-out record information of the stack-out counter is updated in real time. If historical data in the target storage container has been completely exported, the stack-out record information of the stack-out counter is set to a preset value. For example, when local display or execution information is exported, historical record information needs to be read from the "valve stack" data storage structure, and an "export" operation (i.e., a "read" operation) is performed. The value of the "stack-out counter SP" is increased by one for each piece of historical record information read, and the value of the "stack-out counter SP" returns to 0 after the last piece of historical record information is read.

[0056] On the basis of the above technical solutions, the method further comprises: if the to-be-applied instruction information is of a data zero-clearing type, obtaining stack-in record information and stack-out record information of the target storage container; and setting the stack-in record information and the stack-out record information to preset values to clear data in the target storage container.

[0057] The stack-in record information can be the amount of data stacked in real time by a stack-in counter.

[0058] Specifically, if the to-be-applied instruction information is of a data zero-clearing type, stack-in record information and stack-out record information of the target storage container are obtained, and the stack-in record information and the stack-out record information are set to preset values to clear data in the target storage container. For example, the "valve stack" data storage structure can also be subjected to a zero-clearing operation through a command. After zero-clearing, all data in the storage structure are cleared, and the values of the "stack-in counter SP" and the "stack-out counter SP" are both set to 0.

[0059] The technical scheme of the embodiment of the present application comprises the following steps: obtaining to-be-applied instruction information, determining whether the to-be-applied instruction information matches preset instruction information, determining a target storage container corresponding to the to-be-applied instruction information if the to-be-applied instruction information matches the preset instruction information, obtaining data capacity information and a current data capacity corresponding to the target storage container, determining a data storage mode based on the data capacity information and the current data capacity, and performing data storage based on the data storage mode. Based on the above technical scheme, the data storage mode is determined according to the data capacity information and the current data capacity of the target storage container, and then the data storage container is reused, and the data export efficiency in the embedded system is improved.

[0060] Embodiment two

[0061] Figure 4 is a flowchart of a data storage method applied to an embedded system provided by the embodiment of the present application. The embodiment further optimizes the above-mentioned data storage method applied to an embedded system on the basis of the above-mentioned embodiment. The specific implementation manner can be referred to the technical scheme of the embodiment. The technical terms same as or corresponding to those in the above-mentioned embodiment are not described herein.

[0062] The technical scheme provided by the embodiment comprises the following steps: Figure 4

[0063] When the system product software is designed, the designer can abstractly construct a "valve stack" data storage structure according to the actual situation of product function demand and storage resource, and pre-set the storage space depth and content composition of the "valve stack" data storage structure. When the "valve stack" data storage structure is initialized, the "stack-in counter SP" and the "stack-out counter SP" are both set to zero, and the entire "valve stack" data storage container is cleared.

[0064] When a new historical record information is generated, the historical record information needs to be stored in the "valve stack" data storage structure, and then the "stack-in" operation (i.e. the "write" operation) is performed. The "stack-in counter SP" value is increased by one for each historical record information, and the "stack-in counter SP" value remains unchanged after the data storage structure is full. When the local display or the information export is performed, the historical record information needs to be read from the "valve stack" data storage structure, and then the "stack-out" operation (i.e. the "read" operation) is performed. The "stack-out counter SP" value is increased by one for each historical record information, and the "stack-out counter SP" value returns to 0 after the last historical record information is read.

[0065] ​Since the space depth (size) of the "valve stack" data storage structure is fixed and has been set in advance, when the number of historical record information is full of the storage space capacity set in advance, the earliest generated historical record information in the "valve" at the bottom of the "valve stack" data storage structure needs to be deleted through the "valve", and then the data information in the "valve stack" data storage structure is translated to the bottom of the stack in turn, and finally the newly generated historical record information is stored in the storage space. The "valve stack" data storage structure can also be cleared by command. After clearing, all data in the entire storage structure is cleared, and the values of the "stack counter SP" and the "stack counter SP" are both set to zero.

[0066] It should be noted that the historical record information generated by the device is arranged in the storage space in strict accordance with the time point of generation. The latest generated historical record information is always arranged at the top of the "stack" storage structure, and the earliest generated historical record information is always arranged at the bottom of the "stack" storage structure. After local display or information export, there is no need to reorder all the historical record information, and there is no need to perform relatively complex retrieval calculation. At the same time, the "valve stack" data storage structure can be regarded as a whole module. When writing software code, the whole "valve stack" data storage structure can be operated in a modular design idea, reducing the coupling of the software code.

[0067] The technical scheme of the embodiment of the application comprises the following steps: obtaining to-be-applied instruction information, determining whether the to-be-applied instruction information matches preset instruction information, determining a target storage container corresponding to the to-be-applied instruction information if the to-be-applied instruction information matches the preset instruction information, obtaining data capacity information and a current data capacity corresponding to the target storage container, determining a data storage mode based on the data capacity information and the current data capacity, and performing data storage based on the data storage mode. Based on the above technical scheme, the data storage mode is determined according to the data capacity information and the current data capacity of the target storage container, and the data storage container is multiplexed, thereby improving the data export efficiency in the embedded system.
