Fig. 2 is a flowchart of a method of determining a storage partition of a storage unit according to an embodiment of the present application. As shown in fig. 2, the method comprises the steps of:

step S201, a plurality of storage partitions are obtained, each storage partition comprises a plurality of data units, each data unit stores a plurality of fields, and the plurality of fields comprise a use field, a valid field, a data name field, a data length field, a data content field and a data verification field;

specifically, in general, only two storage partitions are required to be set, namely a first storage partition and a second storage partition, and the number of data units included in the two storage partitions is equal, as shown in fig. 3, two areas with the same size are divided on the available space of the storage medium, so that the capacity of one storage space can meet the data storage requirement, in most cases, only one partition (target partition) can be operated, data transfer can be performed only when the storage space is used up, and valid data is copied to the other partition (non-target partition, which can also be called standby partition). As shown in the following figures, each memory partition is divided into small blocks of the same size, each of which may store one data unit, each of which is in turn made up of several sub-blocks. Initially all data units of the memory area are written to 1. And the storage content is managed in a data unit mode, and the correctness of the reading and writing process is ensured by setting various fields.

Wherein, as shown in fig. 3, the respective fields (sub-blocks) of the data unit are explained as follows:

1) Whether to use an identification (i.e., use a field): taking 4 bytes, all 1's indicate that the data unit is empty, i.e. not written with data. If data is written, the flag is set to a magic word that can be self-verified, such as 0xA55B5AA5, i.e. the upper 2 bytes are complements of the lower 2 bytes. When this field is other, then an error is considered to have occurred in writing.

2) Validity identification (i.e., valid field): taking 4 bytes, all 1's indicate that the data is valid. When the data is invalid, the flag is set to a magic word capable of self-checking, such as 0xA55B5AA5, i.e. the upper 2 bytes are complements of the lower 2 bytes. When this field is other, then an error is considered to have occurred in writing.

3) Data name: the data is managed in a key value pair mode, the field is a key, the storage content is a character string, and the character string can be used for judging whether the data exists or not when the data is written.

4) Data length: taking 4 bytes to represent the actual length of the data content, and when this value exceeds the agreed maximum limit, an error is considered to have occurred in writing.

5) Data content: the fixed length is occupied (which may be determined according to specific requirements), and the actual length is obtained from the "data length" field. The data is managed in a key value pair mode, the field is a value, and if the key exists and the values are equal when the data is written, the data is not written.

6) And (3) checking data: the data occupy 2 bytes, which is a numerical value obtained by performing Cyclic Redundancy Calculation (CRC) on the data name, the data length and the data content field, and is used for checking whether errors occur in the data of the parts during writing.

Step S202, detecting each storage partition to obtain a plurality of detection results, wherein the detection results are in one-to-one correspondence with the storage partitions, and the plurality of detection results comprise the effective unit number of the storage partitions, the ineffective unit number of the storage partitions and the blank unit number of the storage partitions, the effective unit number is the number of data units effective by data stored in the storage partitions, the ineffective unit number is the number of data units ineffective by data stored in the storage partitions, and the blank unit number is the number of data units not storing data in the storage partitions;

specifically, each time power is applied, data in a plurality of storage partitions are checked, error checking and even repairing can be performed on various abnormal conditions occurring in the data writing process through various measures, a target partition and a non-target partition are determined through a statistical result, and data of the non-target partition is erased (full writing 1).

The specific implementation steps of step S202 are as follows:

step S2021, detecting a plurality of data units in the storage partition sequentially according to a preset sequence, and sequentially performing usage field detection, valid field detection, data length field detection and data check field detection for each data unit to obtain an initial detection result, where the initial detection result includes one of the data units being valid units, invalid units and blank units;

first, the usage field detection is performed as follows:

step S301, when the usage field meets a first condition, continuing to perform the valid field detection, the data length field detection and the data check field detection in sequence to obtain the initial detection result, wherein the first condition is characterized in that the data unit is not the blank unit;

step S302, when the usage field does not satisfy the first condition and at least one detected data unit is not the blank unit, determining the data unit as the invalid unit;

step S303, determining that the data unit is the blank unit when the usage field does not satisfy the first condition and the detected data units are all the blank units.

Specifically, when the field is all 1, the data unit is represented as a blank unit, when the field is a flag magic word, the data unit is represented as not being the blank unit, the detection of the subsequent field is continued in sequence, and when the field is not all 1 or the flag magic word, the field is proved to be wrong, repair is needed, and the field is set as the flag magic word. And the field can be used for performing a self-checking function, namely, the self-checking can be performed under the condition that the field is in error, so that error checking and even repairing can be performed on various abnormal conditions occurring in the field during the data writing process.

Then, the effective field detection is performed as follows:

step S401, when the usage field satisfies a first condition, continuing to perform the valid field detection, and when the valid field satisfies a second condition, continuing to sequentially perform the data length field detection and the data check field detection, to obtain the initial detection result, wherein the second condition is characterized in that the data unit is the valid unit, and the first condition is characterized in that the data unit is not the blank unit;

Step S402, determining the data unit as the invalid unit when the valid field does not satisfy the second condition.

Specifically, the data unit is represented as an effective unit under the condition that the effective field is all 1, the data unit is proved to be an ineffective unit under the condition that the effective field is a marked magic word, the field is proved to be in error under the condition that the effective field is not all 1 nor is the marked magic word, repair is needed, and the field is set as the marked magic word. And the effective field can perform a self-checking function, namely, can perform self-checking under the condition of field errors, so that error checking and even repairing can be performed on various abnormal conditions of the effective field in the data writing process.

Then, the data length field detection is performed as follows:

step S501, when the usage field meets a first condition and the valid field meets a second condition, continuing to perform the data length field detection, and when the data length field meets a third condition, continuing to perform the data check field detection, to obtain the initial detection result, where the third condition is that a data length represented by the data length field is within a preset length range, the first condition is characterized in that the data unit is not the blank unit, and the second condition is characterized in that the data unit is the valid unit;

Step S502, determining the data unit as the invalid unit when the data length field does not satisfy the third condition.

Specifically, since the data length field does not have a self-checking function, the data length field is used for checking whether an error occurs in the data length field during writing, so that various abnormal conditions occurring in the data length field during data writing can be checked for errors and even repaired.

Finally, the data check field detection is performed according to the following steps:

step S601, when the usage field satisfies a first condition, the valid field satisfies a second condition, and the data length field satisfies a third condition, the data check field detection is continued, and when the data check field satisfies a fourth condition, the data unit is determined to be the valid unit, the fourth condition is that the value of the data check field is a target value and the data written by the data unit is unique, the target value indicates that the data name field, the data length field, and the data content field are correct, the first condition is characterized in that the data unit is not the blank unit, the second condition is characterized in that the data unit is the valid unit, and the third condition is that the data length indicated by the data length field is within a preset length range;

Step S602, determining the data unit as the invalid unit when the data check field does not satisfy the fourth condition and when the field bits of the data check field are not all the preset value;

step S603, repairing the value of the data check field and determining whether the repaired data check field satisfies the fourth condition when the data check field does not satisfy the fourth condition and when the field bits of the data check field are all the preset value.

Specifically, under the condition that the data check field is all 1, the error of the field is proved, the repair is needed, and the new numerical value is obtained by performing Cyclic Redundancy Calculation (CRC) on the data name field, the data length field and the data content field to rewrite the data check field, namely, the data check field cannot be all 1, so that the error check and even the repair can be performed on various abnormal conditions of the data check field in the data writing process.

Step S2022, determining the number of valid units of the memory partition, the number of invalid units of the memory partition, and the number of blank units of the memory partition according to the plurality of initial detection results, so as to obtain the detection results.

Data corruption generally occurs during data writing, and data is checked at the beginning of power-up to ensure data reliability. The power-on data checking process is to check and repair errors possibly occurring in the normal operation process and the data writing process of the power-on data checking process, and determine the current storage partition and the standby storage partition according to a certain judgment basis so as to ensure that the subsequent reading and writing processes can be performed normally.

Step S203, according to at least one of the following: the number of valid units of each storage partition, the number of invalid units of each storage partition, and the number of blank units of each storage partition are determined, and a target partition and a non-target partition are determined, wherein the target partition is the storage partition with the largest number of valid units or the largest number of blank units, the target partition is used for reading and writing data, and the non-target partition is used for continuing to write the data when the target partition is full of data.

Specifically, the data is read and written through the cooperation of the two storage areas, and the data reliability in the reading and writing process is ensured. The memory area operation mainly comprises several main processes of data reading, data writing and power-on data checking. Wherein each power-on data check process identifies a target partition, a non-target partition, and erases the non-target partition data (write-all 1).

The specific implementation steps of step S203 are as follows:

step S2031 of determining, as the target partition, the memory partition having the largest number of effective units when the effective units of at least two memory partitions are different;

for example: a total of 10 memory partitions, wherein the effective unit numbers of 3 memory partitions are different, and the effective unit numbers of the other 7 memory partitions are the same, and the memory partition with the largest effective unit number in the 10 memory partitions is determined as the target partition;

step S2032 of determining, as the target partition, the memory partition having the smallest number of invalid units when the number of valid units of any two memory partitions is the same;

for example, there are 10 storage partitions, where the number of valid units of the 10 storage partitions is the same, but the total number of data units and the number of invalid units of the 10 storage partitions are different, and determining the storage partition with the least number of invalid units of the 10 storage partitions as the target partition;

in step S2033, when the number of valid units of any two of the memory partitions is the same and the number of invalid units of any two of the memory partitions is the same, the memory partition having the largest number of blank units is determined as the target partition.

For example, there are 10 storage partitions, where the number of valid units and the number of invalid units of the 10 storage partitions are the same, but the total number of data units of the 10 storage partitions is different, and determining the storage partition with the largest number of blank units among the 10 storage partitions as the target partition;

specifically, the number of data units of the plurality of memory partitions may be the same or different, and if the number of data units of the plurality of memory partitions is the same, the determination is only required to step S2032, and the determination in step S2033 is not required, whereas if the number of data units of the plurality of memory partitions is different, the determination in step S2033 is further performed. Thus, the maximum number of available units which can be read in the target partition can be ensured, and the maximum number of blank units which can be written in the target partition can be ensured.

Wherein the memory partition is two, according to at least one of the following: after determining the target partition and the non-target partition, the method further includes: copying all valid data in the target partition to the non-target partition and confirming the non-target partition as a current target partition under the condition that target data need to be written and the target partition does not have the blank unit; and erasing the whole content in the target partition, and writing the target data into the current target partition.

The data is written into the blank unit of the current partition in sequence, and the partition switching can be completed by the aid of the standby partition only when the storage partition is full, so that frequent erasing of the storage medium can not be caused. (if the same data name exists, the original data is invalidated).

The method for determining the storage partition of the storage unit comprises the steps of firstly obtaining a plurality of storage partitions, wherein each storage partition comprises a plurality of data units, each data unit stores a plurality of fields, and the plurality of fields comprise a use field, a valid field, a data name field, a data length field, a data content field and a data verification field; detecting each storage partition to obtain a plurality of detection results, wherein the detection results correspond to the storage partitions one by one, the plurality of detection results comprise the effective unit number of the storage partitions, the ineffective unit number of the storage partitions and the blank unit number of the storage partitions, the effective unit number is the number of data units with effective data stored in the storage partitions, the ineffective unit number is the number of data units with ineffective data stored in the storage partitions, and the blank unit number is the number of data units without data stored in the storage partitions; finally according to at least one of the following: the method comprises the steps of determining a target partition and a non-target partition, wherein the target partition is a storage partition with the largest number of effective units or the largest number of blank units, and is used for reading and writing data, and the non-target partition is used for continuing to write the data when the target partition is full of the data. According to the method, the target partition and the non-target partition are determined, so that partition switching is completed by means of one partition when the other partition is full, frequent erasing of the storage medium is not caused, and the problems that the erasing of the storage medium is frequent, the efficiency is low and the service life of the storage medium is influenced in the prior art are solved.

In order to enable those skilled in the art to more clearly understand the technical solutions of the present application, the implementation procedure of the method for determining the storage partition of the storage unit of the present application will be described in detail below with reference to specific embodiments.

The present embodiment relates to a method for determining storage partitions of a specific storage unit, as shown in fig. 4, where the storage partitions are two, and the method includes:

step S1: firstly, carrying out power-on data inspection, then traversing two partitions in sequence from the last data unit of each storage partition, then detecting whether a used field is marked with 1, judging whether the detected data unit is a data unit which is not empty or not under the condition that the used field is marked with 1, proving that the data unit is wrong under the condition that the detected data unit is a data unit which is not empty, setting the data unit as used and invalid, setting the number of invalid units of the storage partition to +1, if the detected data unit is not empty, determining that the data unit is a blank unit, setting the number of blank units of the storage partition +1, then confirming whether the data unit is the last detected data unit, judging a target partition and a non-target partition through the number of valid units, invalid units and blank units if the detected data unit is not empty, and continuously analyzing the next data unit if the detected data unit is not.

Step S2: judging whether the used field is a marked magic word or not under the condition that the used field is not marked with 1, if not, proving that the used field is wrong, repairing, and setting the used field as the marked magic word; if so, detection of the valid field is performed.

Step S3: judging whether the effective field is 1, if the effective field is not 1, determining whether the effective field is a marked magic word, if not, repairing, resetting the effective field as a marked magic word, if the effective field is the marked magic word, determining that the data unit is an invalid unit, storing the number of the invalid units in a partition +1, and then confirming whether the data unit is the last detected data unit, if yes, judging the target partition and the non-target partition according to the number of the effective unit, the invalid unit and the blank unit, otherwise, continuously analyzing the next data unit.

Step S4: and judging whether the data length field exceeds a preset length range under the condition that the effective field mark is 1, determining that the data length field is in error under the condition that the data length field exceeds the preset length range, setting the data unit as invalid, storing the invalid unit number of the partition +1, and confirming whether the data unit is the last detected data unit, if so, judging the target partition and the non-target partition according to the number of the effective unit, the invalid unit and the blank unit, and if not, continuing to analyze the next data unit.

Step S5: judging whether the data check field is 1 or not under the condition that the data length field does not exceed the preset length range, determining that the data check field is wrong under the condition that the data check field is 1, repairing, writing the recalculated check value, namely the effective unit number of the storage partition where the unit is located is +1, and confirming whether the data unit is the last detected data unit, if so, judging the target partition and the non-target partition according to the number of the effective unit, the invalid unit and the blank unit, and if not, continuously analyzing the next data unit.

Step S6: and under the condition that the data check field is not all 1, judging whether the check value is expressed as the error of the data unit, if so, setting the data unit as an invalid unit, and judging whether the data unit is a repeated unit or not, namely comparing the data name field and the data content field of the data unit with the data name field and the data content field of the detected data unit, if not, judging the number of the invalid units in the storage partition to be +1. If the data unit is the repeating unit, the data unit is set as invalid, the number of invalid units in the storage partition is +1, if the data unit is not the repeating unit, the data unit is checked, the number of valid units in the storage partition is +1, whether the data unit is the last detected data unit is confirmed, if the data unit is the last detected data unit, the number of valid units, invalid units and blank units is used for judging the target partition and the non-target partition, and if the data unit is not the repeating unit, the next data unit is continuously analyzed.

After the target partition is determined, all data in the non-target partition is erased, i.e., write-through 1.

The data is written into the blank unit of the current partition in sequence, and the partition switching can be completed by the aid of the standby partition only when the storage partition is full, so that frequent erasing of the storage medium can not be caused. (if the same data name exists, the original data is invalidated)

And (3) circularly reading the data units in the storage area, wherein the data are sequentially written, and when the current data unit is judged to be unused (blank unit), directly jumping out of the circle (the following data units are blank units).
