Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. The present invention is not limited to the embodiment, and other embodiments may be included in the scope of the present invention as long as the gist of the present invention is satisfied.
In a preferred embodiment of the present invention, based on the above problems in the prior art, a FLASH file management system with lifetime management is now provided, for performing storage management on a FLASH file, as shown in fig. 1 and fig. 2, including:
the file storage module 1, the file storage module 1 includes:
the directory area 11 is used for storing the basic information of each Flash file to form a file directory;
a file information area 12 for storing the attribute data of each Flash file in the file directory, the file information area having a plurality of storage blocks 121;
a data area 13 for correspondingly storing the content data of each Flash file in the file directory;
file management module 2, connect file storage module 1, file management module 2 includes:
the balance management unit 21 is configured to store each attribute data in each storage block in a round-robin manner, and set the storage block in which the attribute data is currently stored to a usable state;
the write-in management unit 22 is configured to extract basic information, attribute data, and content data of a file to be written in, write the basic information into the directory area in sequence, write the attribute data into the storage block in the usable state, and write the content data into the file information area;
and the power failure management unit 23 is configured to, when detecting that a power failure occurs in the writing process of the directory area, perform power failure management on the directory area by respectively reading and comparing the directory area and the file information area in the power-on recovery process.
Specifically, in this embodiment, the file storage module 1 is divided into three blocks, so that the basic information, the attribute data, and the content data of the Flash file are respectively stored, and each block is conveniently and respectively managed. The basic information includes but is not limited to a file name of the Flash file, and the attribute data includes but is not limited to a file size and a setup time of the Flash file. By setting the directory area 11 for storing the basic information, the basic information of each Flash file is intensively placed, so that the file retrieval is conveniently carried out according to the basic information, and the file retrieval efficiency is effectively improved. Further, since the file name of the Flash file is fixed, before the file to be written is written, it may be checked whether the file name of the file to be written is stored in the directory area 11, if the file name of the file to be written already exists in the directory area 11, the writing process does not need to perform an erasing operation on the directory area, if the file name of the file to be written does not exist in the directory area 11, the file to be written is a new file, and at this time, the erasing operation needs to be performed on the directory area 11, based on this, the erasing operation frequency of the directory area 11 is low, and the erasing life of Flash is usually about 10 ten thousand times, which can meet the normal use requirement, so in this embodiment, the directory area 11 is not subjected to balanced management.
Taking the attribute data as the file size as an example, since the attribute data of the Flash file with the same file name may be updated in the file size due to the increase and decrease of part of the content data at different acquisition times, the corresponding attribute data is usually updated in real time during each writing of the Flash file, that is, the file information area 12 needs to be frequently erased and written. Based on this, in the present embodiment, by providing a plurality of storage blocks 121 in the file information area 12, the balanced management of the attribute data in the file information area 12 is realized. The set number of the storage blocks 121 can be adjusted according to the requirement of the design service life, and the greater the set number of the storage blocks 121, the longer the service life is. Taking the three storage blocks 121 as an example, the three storage blocks are respectively a first storage block, a second storage block and a third storage block, preferably, each time one of the storage blocks is set to be in a usable state, the other two storage blocks are set to be in an unusable state, when the first storage block is in the usable state, the attribute data written in and read from the first storage block are both directed to the first storage block, when the storage state of the first storage block meets a certain preset trigger condition, the attribute data stored in the first storage block can be moved to the second storage block, when the original storage data in the first storage block is erased, the first storage block is set to be in the unusable state, the second storage block is set to be in the usable state, so as to facilitate the subsequent writing in and reading of the attribute data, and so on, when the storage state of the third storage block meets a certain preset trigger condition, the attribute data in in the third storage block is moved to the first storage block, completing one rotation. Because the erasing frequency of the whole file information area is equally divided into the three storage blocks, the service life of each storage block is effectively prolonged, and the service life of the whole file storage module 1 is prolonged. It should be noted that the above-mentioned rotation method is only one example, and the technical solution is not limited thereto.
Further, in the writing process of the file to be written, firstly writing the basic information of the file to be written into the directory area 1, then writing the attribute data into the corresponding file information area, and further storing the content data into the storage address of the data area according to the storage address of the data area associated with the attribute data.
In this embodiment, since the basic information stored in the directory area 11 and the attribute data stored in the file information area 12 are in one-to-one correspondence, by the above-described writing order, when a power loss occurs during the writing of the directory area 11, due to the writing of the directory area 11 with the basic information at this time, whereas the attribute data has not yet been written due to the power failure, the file information area 12 has no attribute data corresponding to the basic information, therefore, by comparing the stored data in the directory area 11 and the file information area 12, it is possible to locate the write data before the power failure of the directory area 11, in other words, it is possible to determine the normal data and abnormal data stored in the directory area 11, therefore, normal data is reserved, abnormal data is covered when the data is written next time, data loss caused by power failure is minimized, and the phenomenon that the whole directory area is disordered due to power failure in the existing directory area writing process is effectively avoided.
In a preferred embodiment of the present invention, the file information area 12 includes a main information storage area 122 and a standby information storage area 123, wherein a plurality of storage blocks 121 are disposed in the main information storage area 122, and the storage blocks 121 in the standby information storage area 123 correspond to the storage blocks 121 in the main information storage area 122 one to one;
the write management unit 222 writes the attribute data correspondingly to the memory blocks in the usable state in the main information memory area 122 and the spare information memory area 123, respectively.
Specifically, in this embodiment, the main information storage area 122 and the standby information storage area 123 are redundantly arranged in the file information area 12, so that the attribute data is backed up, and the influence on data reading caused by loss or damage of the attribute data stored in the main information storage area 122 due to power failure or other influence factors in the data writing process is avoided.
Further, a plurality of storage blocks 121 are respectively and correspondingly arranged in the main information storage area 122 and the standby information storage area 123, that is, the main information storage area 122 and the standby information storage area 123 are both managed in a balanced manner, and the service life is effectively prolonged.
In a preferred embodiment of the present invention, the file management module 2 further includes a reading management unit 24, and the reading management unit 24 includes:
the first checking subunit 241 is configured to obtain corresponding attribute data by matching the basic information of the file to be read in the main information storage area, check the attribute data, output a first checking signal when the checking is passed, and output a second checking signal when the checking is not passed;
the second checking subunit 242, connected to the first checking subunit 241, is configured to obtain corresponding attribute data by matching the second checking signal and the basic information in the standby information storage area, check the attribute data, output a third checking signal when the checking is passed, and output a fourth checking signal when the checking is not passed;
a first processing subunit 243, respectively connected to the first checking subunit 241 and the second checking subunit 242, for reading the corresponding content data in the data area according to the first checking signal and the corresponding attribute data, and reading the corresponding content data in the data area according to the third checking signal and the corresponding attribute data;
the second processing sub-unit 244 is connected to the second checking sub-unit 242, and is configured to replace the attribute data stored in the main information storage area with the attribute data stored in the spare information storage area according to the third checking signal, and perform system formatting according to the fourth checking signal.
Specifically, in this embodiment, since the attribute data stored in the main information storage area 122 may cause data loss or damage due to factors such as hardware power failure, the attribute data is verified after being read, and only after the main information storage area 122 and the standby information storage area 123 both pass the verification, the attribute data is complete and correct, so as to ensure the correctness of the read data.
In the preferred embodiment of the present invention, the attribute data is verified using a checksum algorithm.
In a preferred embodiment of the present invention, the attribute data includes a file type of a file to be written;
each storage block is divided into a plurality of storage areas in advance, each storage area is associated with a preset file type, and each storage area is associated with at least one storage address in a data area;
the write management unit 22 writes the attribute data into the storage area associated with the corresponding file type, and then writes the content data of the file to be written into the data area according to the storage address associated with the storage area.
Specifically, in this embodiment, the application may be applied to an application scenario that has standard requirements on the type and the file size of a storage file, such as an electric power project application scenario, where the Flash file to be stored has a preset file type, and there is an upper limit requirement on the file size of each Flash file, that is, the file type and the file size of the file to be written in are predictable. Based on the above, the attribute data of each Flash file can be stored in the storage area associated with the matched file type.
In a preferred embodiment of the present invention, each memory region is pre-divided into a plurality of sub-regions, and each sub-region is associated with at least one memory address in the data region;
the write management unit 22 writes the attribute data into the corresponding sub-area in the storage area associated with the corresponding file type, and writes the content data of the file to be written into the data area according to the storage address associated with the sub-area.
Specifically, in this embodiment, based on the file to be written in which the file type and the file size are predictable, the storage area may be pre-divided into a plurality of sub-areas, and preferably, the storage space of each sub-area is set to be not smaller than the upper limit of the file size, so that when the attribute data is written in, and the original sub-area needs to be covered, only the stored data in the original sub-area needs to be erased, and then the attribute data is written in, and calculation of the data size is not needed, and then subsequent operations such as allocation of the storage space and the like are performed according to the data size, thereby effectively increasing the storage rate.
In a preferred embodiment of the present invention, the balance management unit 21 moves the attribute data in the original storage block to the next storage block when a preset trigger condition is satisfied, and sets the original storage block to be in an unavailable state and sets the next storage block to be in an available state.
Specifically, in this embodiment, the preset trigger condition may be a preset time, that is, the attribute data may be moved at a certain time every day, but not limited thereto.
In the preferred embodiment of the present invention, each memory block 121 is associated with a flag bit, and the balance management unit 21 implements setting of the corresponding memory block to the unavailable state or the available state by assigning a value to the flag bit.
Specifically, in this embodiment, a flag bit associated with a memory block may be assigned a 0 value to indicate an unavailable state, while a flag bit may be assigned a 1 value to indicate a usable state.
