Embodiment one:
the application provides a card opening device which can be used for opening a card of a storage device quickly and conveniently. Referring to fig. 1 to 6, the card opening device includes a main control chip 10, a mother card interface 11 and at least one daughter card interface 12 respectively connected to the main control chip 10, and a test unit 13 connected to the main control chip, wherein the mother card interface 11 is used for inserting a mother card 20, and the daughter card interface 12 is used for inserting a daughter card 30.
The mother card 20 includes a first control chip 21 and a first memory chip 22, the daughter card 30 includes a second control chip 31 and a second memory chip 32, and when the mother card 20 and the daughter card 30 are respectively inserted into the mother card interface 11 and the daughter card interface 12, the main control chip 10 performs communication interaction with the first control chip 21 of the mother card 20 and the second control chip 31 of the daughter card 30, and controls reading and writing of card data information under the condition of power on.
In one embodiment, the main control chip 10 has an SRAM integrated therein for loading programs. The main control chip 10 is respectively connected with a mother card interface 11 and a daughter card interface 12, the mother card interface 11 is used for inserting the mother card 20, the daughter card interface 12 is used for inserting the daughter card 30, and the daughter card 30 and the mother card 20 are the same type of storage devices.
Referring to fig. 4 and 6, in one embodiment, the first memory core 21 of the mother card 20 stores firmware, a card opening program, and file system data.
Specifically, the main control chip 10 collects file system data in the mother card 20 to form first image data of the mother card file system, where the first image data includes data of a partition of blocks corresponding to each block.
The file system data of the mother card 20 refers to a method and a data structure of the first control chip 21 for defining files in the first memory chip 22, that is, a method for organizing files on the first memory chip 21, and the executed functions include managing and scheduling a memory space of the files, providing a logical structure, a physical structure and a memory method of the files, realizing mapping from a mark to an actual address of the files, realizing control operation and access operation of the files, realizing sharing of file information, providing reliable file confidentiality and protection measures, providing security measures of the files, and the like. When firmware is installed on the file system, the various processes of the system file are thereby started.
The main control chip 10 collects file system data in the mother card, and the first image data forming the mother card file system includes data of the partitions of the blocks corresponding to each block. The division of the blocks may be divided into an MBR area, a DBR area, a FAT area, a DIR area, and a DATA area.
The MBR area (Main Boot Record area) contains a series of parameters of a memory and a section of Boot program, wherein the Main function of the Boot program is to detect whether the total table is normal or not and Boot an operating system on a partition with an activation flag after the hardware completes self-checking, and give control to the Boot program. The MBR area is generated by the partition program, but is not dependent on firmware.
The DBR section (Dos Boot Record) is the first block that the operating system can access and includes a Boot loader and a BPB (Bios Parameter Block present partition parameter Record table). The main task of the boot program is to judge whether the front-end file of the root directory of the local area is the boot file of the firmware after the MBR gives the control right of the system to the boot program, if so, the file is read into the memory, and the control right is given to the file. The BPB parameter block records important parameters such as a start sector, an end sector, a file storage format, a hard disk medium descriptor, a root directory size, a FAT number, a size of an allocation unit and the like of the partition. DBR is generated by a high-level formatting program.
The FAT area (File Allocation Table file allocation table) is used to indicate the linked storage relationship of files in the storage chip, and to record the storage locations that have been occupied and the storage locations that indicate the subsequent content. Because of the importance of FAT for file management, there is a backup of FAT, i.e., a same FAT is built up behind the original FAT. All items in the initially formed FAT are designated as "unoccupied", but if there is a local corruption in the memory chip, the formatter detects the location of the corruption, marks the corresponding item as the corruption, and no longer stores the file in that location at a later time.
The DIR area (Directory root Directory area) immediately follows the second FAT table, and records a start unit of each file (Directory) under the root Directory, an attribute of the file, and the like. When the file is located, the operating system can know the specific position and size of the file in the hard disk by combining the FAT table according to the starting unit in the DIR.
The DATA area is used to store DATA and occupies most of the DATA space on the hard disk.
In one embodiment, the second memory chip 32 of the daughter card 30 is configured to store a mapping table mapped from the mother card 20 to the daughter card 30 and a file system established according to mirror data of the file system of the mother card, and the daughter card maps the memory block according to the mapping table.

The test unit 13 is configured to perform a read-write comparison test on the daughter card according to the mirror image data of the file system in the mother card, so as to determine whether the daughter card is normal.
Specifically, the method includes the steps of obtaining first image data of a file system in the mother card 20, obtaining second image data of the file system in the daughter card 30, performing exclusive or comparison on the first image data and the second image data, if the first image data and the second image data are the same, indicating that the daughter card is normally opened, and if the first image data and the second image data are different, restarting the opening of the daughter card.
The first mirror image data is located at a first position of a file system in the mother card, the second mirror image data is located at a second position of the file system in the daughter card, and the first position corresponds to the second position.
In this embodiment, since the buffer capacity of the main control chip is limited, the entire file system cannot be written completely, so that the mirror image data of the file systems of the mother card and the daughter card are obtained in sections and compared, and since the file systems of the mother card and the daughter card are the same at this time, the first position of the first mirror image data file in the file system of the mother card is the same as the second position of the second mirror image data file in the file system of the daughter card.
The device further comprises a power interface 14, the power interface 14 being adapted to be connected to an external power source for powering the components.

After the main control chip 10 is connected to the mother card 20 and the daughter card 30, the main control chip 10 checks whether the mapping summary table exists in each daughter card 30, and if the mapping summary table does not exist, the writing of the card opening information to the daughter card 30 is controlled.
Specifically, the main control chip 10 reads the card opening program in the mother card 20 and writes the card opening program into the daughter card 30, and the second control chip 31 of the daughter card 30 runs the card opening program and controls to scan the second memory chip 32 in the daughter card 30, and based on the scanned information, creates a total table as a mapping total table for mapping the memory blocks in the second memory chip and testing and screening the quality of the daughter cards.
After the scanning is completed, firmware is obtained from the mother card 20 and written into the daughter card 30. Specifically, the daughter card 30 sends an instruction to the main control chip 10, and the main control chip 10 controls the reading of the firmware from the mother card 20 and the writing of the firmware into the daughter card 30 according to the instruction. Based on the scanned information, the firmware is written at the starting point of the mapping table, namely, the firmware is placed in a front storage block in the mapping table, so that the firmware is directly read from the beginning of the mapping table.
Specifically, the screening the good blocks of the daughter card includes:

Specifically, the main control chip checks whether a mapping table exists in the sub-card, and if the mapping table does not exist, the main control chip controls the sub-card to execute the card opening steps of S101-S103.
In an embodiment, the obtaining the mirror image data of the file system of the mother card and writing the mirror image data into the daughter card specifically includes:
The main control chip controls the mirror image file data of the file system data of the mother card to be written into the daughter card, wherein the file system data of the mother card refers to a method and a data structure of a first control chip for definitely storing files in the chip, namely a method for organizing the files on the first storage chip. When firmware is installed on the file system, various processes of the system file are controlled to be started.
The master control chip collects file system data in the mother card to form mirror image data of the file system of the mother card, wherein the mirror image data of the file system comprises data of blocks corresponding to each block. The division of the blocks may be divided into an MBR area, a DBR area, a FAT area, a DIR area, and a DATA area.
Specifically, the MBR area (Main Boot Record area) includes a series of parameters of the memory and a section of Boot program, wherein the Boot program mainly serves to detect whether the summary is normal or not and Boot the operating system on the partition with the activation flag after the hardware completes self-checking, and gives control to the Boot program. The MBR area is generated by the partition program, but is not dependent on firmware.
The DBR section (Dos Boot Record) is the first block that the operating system can access and includes a Boot loader and a BPB (Bios Parameter Block present partition parameter Record table). The main task of the boot program is to judge whether the front-end file of the root directory of the local area is the boot file of the firmware after the MBR gives the control right of the system to the boot program, if so, the file is read into the memory, and the control right is given to the file. The BPB parameter block records important parameters such as a start sector, an end sector, a file storage format, a hard disk medium descriptor, a root directory size, a FAT number, a size of an allocation unit and the like of the partition. DBR is generated by a high-level formatting program.
The FAT area (File Allocation Table file allocation table) is used to indicate the linked storage relationship of files in the storage chip, and to record the storage locations that have been occupied and the storage locations that indicate the subsequent content. Because of the importance of FAT for file management, there is a backup of FAT, i.e., a same FAT is built up behind the original FAT. All items in the initially formed FAT are designated as "unoccupied", but if there is a local corruption in the memory chip, the formatter detects the location of the corruption, marks the corresponding item as the corruption, and no longer stores the file in that location at a later time.
The DIR area (Directory root Directory area) immediately follows the second FAT table, and records a start unit of each file (Directory) under the root Directory, an attribute of the file, and the like. When the file is located, the operating system can know the specific position and size of the file in the hard disk by combining the FAT table according to the starting unit in the DIR.
The DATA area is used to store DATA and occupies most of the DATA space on the hard disk.
In one embodiment, the method further comprises S104, screening good blocks of the daughter card.
Specifically, the screening of the good blocks of the daughter card includes:
reading the second mirror image data written into the file system of the sub card;
and determining whether the read second mirror image data of the system file is correct or not through an ECC check circuit, classifying the unstable good block into a bad block if the read second mirror image data of the system file is incorrect, and then writing the second mirror image data of the file system into other good blocks again.
Specifically, after the main control chip writes the mirror image data of the file system in the mother card into the daughter card, the daughter card establishes the file system according to the mirror image data, and the file system data in the mother card and the file system data in the daughter card are identical, so that the mirror image data of the identical file system data can be used for read-write test. The above partitions can show that the file system is used for dividing the blocks and fixedly writing the data, and basically the file system represents a binary file of 0/1 at the bottom layer, so that the main control chip reads out the first mirror image data of the file system in the mother card, reads out the second mirror image data of the sub-card file system, and then carries out exclusive-or comparison on the first mirror image data and the second mirror image data to judge whether the card is opened successfully.
The main control chip obtains the mirror image data of the file system of the mother card and writes the mirror image data into the daughter card, the daughter card establishes the file system according to the mirror image data, please refer to fig. 4 and 5, it can be seen that the file system divides the whole memory area of the mother card into areas, such as a data memory area, a card data area (including firmware and card opening program), a mapping table area and a block area, corresponding data is written in each area, and because the daughter card establishes the file system according to the mirror image data of the mother card, the data information and the memory area corresponding to the mother card are distributed in the storage area of the daughter card. The DATA storage area occupies 93% -97% of the system storage area of the daughter card, in which case DATA is not stored in all blocks, but it will be understood that DATA storage is 0/1 mode, and in a block without DATA itself, the block is filled with 0's in its entirety to represent no DATA. Therefore, the read-out of the 0-filled block in the mother card and the daughter card can be also subjected to a comparison test.
When the main control chip writes the mirror image data of the file system into the sub-card, the good blocks of the sub-card can be screened, as in fig. 4 and 5, the bad blocks of "x" are identified, and the good blocks of "v" are identified. The method specifically comprises the steps of performing complete writing and reading in a sub-card, correspondingly writing first mirror image data of a mother card system file into the good sub-card by a main control chip in the process of transmitting the first mirror image data of the mother card system file to the sub-card, reading out the sub-card file system and obtaining second mirror image data of the sub-card file system, determining whether the read second mirror image data of the sub-card file system is correct or not by an ECC check circuit in a bottom layer, classifying the unstable good sub-card file system into bad sub-card if the read second mirror image data of the sub-card file system is incorrect, and writing the data into other good sub-card file systems again.
