In order that the above-recited objects, features and advantages of the present invention will be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.
Fig. 1 shows a flow chart of a data processing method based on a rotation pool.
As shown in fig. 1, the application discloses a data processing method based on a rotary pool, which comprises the following steps:
s102, acquiring data to be stored, and judging the end storage position of a current storage disk to store the data to be stored;
s104, if the tail end storage position does not reach a preset rotation area, the data to be stored is directly stored in a sector of the storage disc;
s106, if the tail end storage position reaches the rotation area, carrying out storage position offset operation, and updating the position of the rotation area so as to store the data to be stored into the sector of the storage disk;
S108, acquiring a read data packet, and calculating a storage address based on the read data packet and a preset address calculation formula so as to read and output data in the storage address;
s110, responding to abnormal data detection of the user terminal, identifying abnormal factors in the storage disk sector, and outputting data in the sector with the abnormal factors to the user terminal.
It should be noted that, in this embodiment, when there is data to be stored, the data to be stored is first obtained, and the end storage position of the current storage disk is determined to store the data to be stored, where the storage disk uses flash storage as an example, and correspondingly, different end storage positions correspond to different storage modes, if the end storage position does not reach a preset rotation area, the data to be stored is directly stored in a sector of the storage disk, which indicates that the current data storage stage is not stored in the rotation area, so that there is no need to update the rotation area, and if the end storage position reaches the rotation area, there is a need to perform a storage position offset operation, and update the position of the rotation area, so that the data to be stored is stored in the sector of the storage disk.
Further, when the user side needs to read data, the corresponding read data packet is obtained first, so that a storage address is calculated based on the read data packet in combination with a preset address calculation formula, the data in the storage address is read and output, and accordingly, the storage addresses corresponding to different storage data are different, so that the currently needed storage address needs to be obtained according to the data in the corresponding range in the read data packet in combination with the address calculation formula, and specific calculation steps are described later.
Further, when an abnormal situation occurs, for example, when the smart meter is damaged or flash storage is in problem, abnormal data detection of the user end needs to be responded, so that abnormal factors existing in the storage disk sector are identified, and data in the sector with the abnormal factors are output to the user end for the user to conduct research, reading and judgment.
According to an embodiment of the present invention, the obtaining data to be stored, judging a terminal storage position of a current storage disk to save the data to be stored, specifically includes:
identifying the carousel based on the storage disk, wherein the storage disk comprises m+1 sectors, and the carousel is the m+1th sector;
Judging the end storage position of the storage disk, wherein,
if the sector sequence number corresponding to the terminal storage position is smaller than or equal to m, storing the data to be stored into the sector corresponding to the storage disk;
if the sector sequence number corresponding to the tail end storage position is equal to m+1, carrying out storage position offset operation, wherein the offset operation specifically comprises the step of counting the number of times of updating the rotating area position so as to determine the updated sector position of the rotating area; and storing the data to be stored into the sector of the next bit after the updated sector position.
In this embodiment, as shown in fig. 2, taking a storage disc with m+1 sectors as an example, taking the last sector with a sequence number as the rotation area, that is, the rotation area is the m+1st sector, the end storage position corresponds to the sector where the end data stored in the storage disc is located, and correspondingly, if the sequence number of the sector corresponding to the end storage position is smaller than or equal to m, it indicates that the rotation area does not need to update the position, and the data to be stored is stored in the sector corresponding to the storage disc at this time, and correspondingly, the currently stored sector is generally the first sector; however, when the end position is equal to m+1, that is, it indicates that the currently stored sector is no longer the first sector, an offset operation needs to be performed, specifically, first, the updated position of the rotation area is determined, so that the data to be stored is saved in the updated sector of the next bit of the rotation area, the updated sector position of the rotation area can be determined by counting the update times of the rotation area, and then the data to be stored is saved in the updated sector of the next bit of the position of the sector, where m is a natural number and is at least greater than "2", accordingly.
According to an embodiment of the present invention, the updating the number of times of the rotation area location to determine the updated sector location of the rotation area specifically includes:
counting once after updating the position of the rotating area once, and accumulating to obtain a counting result Q;
and updating the sector position of the rotating area according to the counting result Q, wherein the updated position of the rotating area is the sector with the sequence number Q in the storage disk.
It should be noted that, in this embodiment, when the rotation area position is updated, the updated sector position of the rotation area is obtained by counting, specifically, counting is performed once after the rotation area position is updated once, and the counting result Q is obtained by accumulating; and updating the sector position of the rotating area according to the counting result Q, wherein the updated position of the rotating area is the sector with the sequence number Q in the storage disk, and correspondingly, Q can be far larger than m, but the Q value is automatically subtracted by m+1 every time Q is larger than m+1, so that the sector with the sequence number Q is always positioned in the original sector of the current storage disk and belongs to the sector range of [1, m+1 ].
According to an embodiment of the present invention, the obtaining a read data packet, calculating based on the read data packet in combination with a preset address calculation formula to obtain a storage address, so as to read data in the storage address and output the data, specifically includes:

According to an embodiment of the present invention, the method further comprises: and synchronously storing the currently identified abnormality factors into the sector currently storing data when the ammeter abnormality and/or the storage disk abnormality are identified, wherein the abnormality factors at least comprise ammeter abnormality factors and storage disk abnormality factors.
It should be noted that, in this embodiment, when data is stored, the anomaly factor is synchronously stored, and accordingly, when the ammeter anomaly and/or the storage disk anomaly are identified, the anomaly factor that is currently identified is synchronously stored into the sector that is currently storing data, for example, when the data is being stored into the sector 2, no new data is stored due to occurrence of the storage disk anomaly, at this time, the anomaly factor that is identified is synchronously stored into the sector 2, and the smart meter is always normal, and after the temporary anomaly recovery of the storage disk, the data to be stored (for example, the smart meter data) will be stored into the sector 3 soon, so that in order to enable the user to better analyze the anomaly data, after storing the anomaly factor into the sector 2, the user is not required to retrieve the data in the sector 3, and only needs to directly retrieve the data in the sector 2, which is time-saving and efficient.
According to an embodiment of the present invention, the responding to abnormal data detection of the user terminal identifies an abnormal factor in the storage disk sector, and outputs data in the sector where the abnormal factor exists to the user terminal, specifically including:
acquiring an abnormal data detection command input by a user terminal to respond;
Traversing data stored by each sector of the storage disk to identify the anomaly factors;
and extracting all data in the sector with the abnormal factor to output to the user terminal.
It should be noted that, in this embodiment, after the user inputs the abnormality detection command, the abnormality detection command is responded to, and the data stored in each sector of the current storage disk is traversed, so that the abnormality factor is identified, and correspondingly, the data in the sector where the abnormality factor exists is extracted and output to the user terminal for analysis.
It is worth mentioning that the method further comprises verifying whether the rotation area rotates, specifically comprises:
acquiring the erasing times of the sectors in the storage disk
；
Comparing the number of erasures
And the size of the count result Q, wherein,
if the number of times of erasing
The result is the same as the counting result Q, and the correct rotation of the rotation area is indicated;
if the number of times of erasing
And if the number is different from the counting result Q, indicating that the rotation region rotates by mistake.
It should be noted that, in this embodiment, the wrap-around area is rotated once every time, indicating that there is a sector to be erased, and accordingly, the number of erasures
The same as the count result Q should indicate that the current round-robin region is correctly round, otherwise, it is incorrectly round.
It is worth mentioning that when an erroneous rotation occurs, the method further comprises:
stopping storing the data to be stored into the storage disk, and taking the sector of the current error cycle as a target sector;
storing the preset self-checking data into the target sector to judge whether the target sector is abnormal or not, wherein,
and if the self-checking result is normal, indicating that the current target sector has no abnormal storage.
It should be noted that, in this embodiment, due to the problem of error rotation, that is, the problem that the target sector corresponding to the storage disk may have a storage abnormality, the data cannot be stored, resulting in the number of erasures
And when the self-checking data is stored in the target sector, the problem that the storage abnormality of the current target sector is not caused is identified.
It is worth mentioning that when an erroneous rotation occurs, the method further comprises:
stopping storing the data to be stored in the storage disk;
and storing the data to be stored into the storage disk for the second time after the preset time is over, and judging the rotation result, wherein,
if the rotation result is normal, indicating that the current storage disk is not abnormal, and continuing to store the data to be stored;
and if the rotation result is abnormal, indicating that the current storage disk is abnormal, and detecting the data to be stored.
It should be noted that, in this embodiment, since a temporary bug occurs during storage, it is necessary to perform secondary storage on the data to be stored after the preset time is over, and determine the storage disk based on the rotation result, where if the rotation result corresponding to the secondary storage is normal, it indicates that there is no abnormality in the current storage disk, and subsequent data may be continuously stored, and if the rotation result is abnormal, it indicates that there is abnormality in the current storage disk, and the data to be stored may be used to detect the storage disk to identify a specific sector, where the preset time may be "1min".
It should be noted that the detecting the storage disc by using the data to be stored to identify a specific sector specifically includes:
when the secondary storage corresponding rotation result is abnormal, identifying the sector currently storing data as a sector to be tested;
extracting a sector of a next bit of the sector to be detected as a detection sector, storing the data to be stored into the detection sector, judging the rotation result of the data to be stored in the detection sector, wherein,
if the corresponding rotation result is normal, indicating that the sector to be tested is abnormal;
and if the corresponding rotation result is abnormal, indicating that the current storage disk is abnormal.
It should be noted that, in this embodiment, when analyzing an abnormal situation, the to-be-stored data may be used to determine a storage disk and a sector in the storage disk, where a sector of the current stored data is used as a to-be-detected sector, a sector next to the to-be-detected sector is used as a detection sector, the to-be-stored data is stored in the detection sector, and a rotation result of the to-be-stored data in the detection sector is determined, where if the rotation result is normal, it is indicated that the to-be-detected sector in the storage disk is abnormal, otherwise, it is indicated that the current storage disk is abnormal, and the data cannot be stored.
