The data storage method provided by the present application will be described in detail below with reference to specific embodiments.

Referring to FIG. 1 , a schematic flowchart of a data storage method is provided in an embodiment of the present application. As shown in FIG. 1 , the method in this embodiment of the present application may include the following steps S101-S103.

S101, when a unit data block in the original data is received by the original storage module, obtain a first check value in the unit data block.

The original data is the data that needs to be transmitted, and the original data is stored in the original storage module. When the transmission is required, the original storage module transmits the original data to the destination storage module via the data storage device, and the original storage module is the data. the sender.

The unit data block refers to that when the original data is transmitted, due to the large size of the original data, the original data is divided into multiple data segments and transmitted in sequence, and a unit data block includes a data segment and the first calibration of the data segment. test value. The first check value is the check value calculated according to the data fragment in the data block of the same unit, and the first check value and the data fragment are sent to the data storage device by the original storage module.

The check value can be a cyclic redundancy check code obtained by cyclic redundancy check (Cyclic Redundancy Check, CRC), referred to as a cyclic code, which is a check code with error detection and error correction capabilities. The length can be arbitrarily selected. The principle of using CRC for verification is: perform polynomial calculation on the data to be verified, and attach the obtained result to the back of the data. At the same time, the receiving device also executes the same algorithm to obtain a verification value, which is the same as the previous result. Compare to ensure the correctness and integrity of data transmission.

The check data length, polynomial, initial value and result XOR value involved in the CRC check value algorithm can be set when the data storage device leaves the factory, or can be set on the original storage module, destination storage module or data storage device .

The length of the check data of the first check value can be preset on the original storage module or data storage device, and obtaining the first check value in the unit data block is to obtain the end length of the unit data block as the check data. length of data.

Further, the original storage module can add a restoration check digit to the unit data block. If the data storage device recognizes that the restoration check digit is 0, then the content in the unit data block needs to be verified before it can be stored. If the data storage device recognizes that the restoration check bit is 1, the content in the unit data block can be directly stored without checking.

S102: Acquire a data segment of the unit data block, and calculate a second check value of the unit data block.

The data storage device adopts the same check algorithm as that of the original storage module, and the obtained data segment of the unit data block is checked by the check algorithm to obtain a second check value.

For example, in the algorithm for calculating the CRC check value set in the data storage device, the length of the check data is 4 bits, the polynomial used for calculation is the two-digit hexadecimal value 03, and the initial value is the two-digit hexadecimal value 00. Figure 2 is a schematic diagram of an example of calculating the second check value. The obtained data in the unit data block is "202010011000", and the first check value of the unit data block can be extracted as "1000". Fragment is "20201001". The data storage device calculates the data segment according to the setting algorithm, and can obtain the second check value "1000". If the first check value is the same as the second check value, it indicates that the data segment of the unit data block is transmitted completely.

S103, when the first check value matches the second check value of the unit data block, store the data segment in the unit data block according to the restoration address of the destination storage module.

The destination storage module is the receiving end for the original storage module to transmit the original data via the data storage device, and the data storage device stores the received data fragments at the restoration address of the destination storage module according to the receiving sequence and generates storage data.

If the first check value is the same as the second check value of the unit data block, the data storage device confirms that the transmission of the data segment in the unit data block is complete and correct, and saves the data segment in the destination storage module on the corresponding recovery address.

Further, when all the unit data blocks of the original data are transmitted, the destination storage module can extract the stored data according to the restoration address, and the stored data is the original data sent from the original storage module to the destination storage module.

In the embodiment of the present application, the first check value in the unit data block is obtained, and the second check value is calculated based on the data segment of the unit data block. When the verification values match, the data segment in the unit data block is stored according to the restoration address of the destination storage module. By comparing the first check value and the second check value, it is determined whether the transmission of the data segment is complete, which ensures the integrity of the data during the data transmission process.

Referring to FIG. 3 , a schematic flowchart of a data storage method is provided in an embodiment of the present application. As shown in FIG. 3 , the method in this embodiment of the present application may include the following steps S201-S208.

S201, when a unit data block in the original data is received by the original storage module, obtain a first check value in the unit data block.

For details, refer to S101, which will not be repeated here.

S202: Acquire the last unit data block of the unit data block based on the arrangement order of the unit data blocks in the original data, and determine the second check value corresponding to the last unit data block as the value of the unit data block. Check the reference value.

The check reference value is the initial value of the check value of the calculated data segment in the calculation unit data block, and can affect the result of the check value. The check reference value will change according to different unit data blocks. The second check value of the previous unit data block is the check reference value of the unit data block, that is, the check result of the previous unit data block will affect the The verification result of the unit data block not only verifies the integrity of the data segment of the unit data block, but also verifies the previous verification result, which enhances the security and reliability of data transmission.

For example, if the second check value of the previous unit data block is a four-digit binary number 1011, and the second check value is converted into a two-digit hexadecimal number 0B, the data storage device confirms that 0B is the unit data block , that is, the initial value used when the unit data block calculates the second check value.

Further, after the data storage device determines the check reference value, it sends the check reference value to the original storage module, and the original storage module calculates the check reference value based on the received check reference value and the data segment of the unit data block. The first check value of the unit data block. Alternatively, after the data storage device confirms that the transmission of the previous unit data block is complete, it may send a unit block transmission completion notification to the original storage module, and the original storage module may directly use the first check value of the previous unit data block as the The check reference value of the unit data block, and the first check value is calculated based on the reference value and the data segment of the unit data block to which it belongs.

Further, the check data length of the first check value and the second check value can be increased according to the order of the unit data blocks, and the original storage module generates the first check value according to the check data length of the unit data block. , and the data storage device calculates the second check value according to the same length of the check data. For example, a feasible method for increasing the length of the check data is that the length of the check data is in the same order as the unit data block, the length of the check data of the first unit data block is 1 bit, and the length of the check data of the nth unit data block is 1 bit. is n bits.

Further, the check reference value may also be used as a polynomial in the calculation of the CRC check value or the result XOR value, etc. to calculate the second check value of the unit data block.

Further, if the unit data block is the first unit data block of the original data, and there is no previous unit data block at this time, the check reference value of the unit data block is a preset initial reference value. , the initial reference value can be set when the data storage device leaves the factory, or it can be set on the original storage module, the destination storage module or the data storage device, or the first data block of the last unit data block in the last transmission of data can be used. Two check values.

S203: Acquire a data fragment of the unit data block, and calculate a second check value of the unit data block based on the data fragment in the unit data block and the check reference value.

Using the check reference value as an initial value, calculate the CRC check value of the data segment in the unit data block, and use the obtained result as the second check value of the unit data block. Likewise, the second check value of the unit data block will be used as the check reference value of the next unit data block.

S204, adding the restored fixed address to the received data length of the original data in the destination storage module to generate a restored address of the unit data block, where the restored fixed address is the initial storage of the original data in the destination storage module address.

The restoration fixed address is the initial address of the original data stored in the destination storage module, which is a preset first address for storing the original data, which can be set when the destination storage module leaves the factory, or can be stored in the original storage module. The setting is made on the module or data storage device and sent to the destination storage module, or the setting is made on the destination storage module. Of course, when historical data is stored in the destination storage module, the first address after storing the historical data may be used as the restoration fixed address for storing the original data.

The received length of the original data in the destination storage module refers to the total length of other data segments in the destination storage module that have been stored and belong to the same original data as the data segments in the unit data block. The restoration address is the first address where the data segment in the unit data block is stored in the destination storage module, and the restoration address can be calculated by adding the restoration fixed address to the received length.

For example, as shown in Figure 4 is a schematic diagram of an example of calculating the restoration address, the restoration fixed address set in the data storage device is 0000, and the received length obtained is 500 bits, then the restoration fixed address and the received length can be obtained. The recovery address of the unit data block is 01F4.

Further, a feasible method for calculating the restoration address is: adding the restoration address of the previous unit data block to the length of the data fragment in the previous unit data block to obtain the restoration address of the unit data block.

Further, if the unit data block is the first unit data block of the original data, the received length at this time is 0, and the restoration fixed address is the restoration address of the unit data block.

S205: Determine whether the first check value matches the second check value of the unit data block.

It is judged whether the first check value is the same as the second check value of the unit data block, and if they are the same, S206 is executed, and if they are not the same, S207 is directly executed.

S206, when the first check value matches the second check value of the unit data block, according to the initial storage address of the original data in the destination storage module, perform a check on the data in the unit data block. Fragments are stored.

If the first check value and the second check value of the unit data block are the same, that is, the data fragments in the unit data block are transmitted completely, the data storage device stores the data fragments of the unit data block in the destination In the recovery address in the memory module.

S207, using the data length of the data segment to update the received data length.

After the data fragment in the unit data block is stored in the destination storage module, add the length of the received data to the length of the data fragment in the unit data block, and confirm the result as the received data length for the next step. A unit data block calculates the recovery address.

S208, when the first check value and the second check value do not match, output a transmission error notification.

If the first check value and the second check value of the unit data block are different, that is, the data segment in the unit data block is incompletely transmitted or has an error, a transmission error notification is sent to the original storage module , which informs the original storage data module that there was an error in the transmission.

Further, when the original storage data module receives the transmission error notification, it will recalculate the first check value and send the unit data block. If the transmission error notification received by the original storage data module during the transmission of an original data exceeds the error notification threshold, it will output an error warning to notify the relevant technical personnel to troubleshoot possible problems. The error notification threshold refers to a critical value of the number of transmission error notifications received in the transmission of an original data, and exceeding this value indicates that there is a problem in the data transmission process.

Further, when the unit data block is the last unit data block of the original data, the data length of the stored data is obtained in the destination storage module, and the stored data is in the destination storage module, with the The initial storage address of the original data in the destination storage module is the first address, and the length is the data of the received data length;

When the data length of the stored data is different from the data length of the original data, a data error notification is output.

The unit data block is the last unit data block of the original data, and after the data fragment is stored in the destination storage module, the data length of the stored data in the destination storage module is obtained, and the length of the stored data is compared with the length of the original data. .

If the data length of the stored data is the same as the data length of the original data, the data storage device confirms that the original data has been transmitted and the transmitted data is complete, and can output a transmission completion notification.

If the data length of the stored data is different from the data length of the original data, the data storage device confirms that the transmission of the original data is incomplete, and outputs a data error notification.

Further, a method for confirming that the unit data block is the last unit data block is: if the length of the data fragment in the unit data block is less than the single transmission length of the original storage module, then confirming the unit data block. is the last unit data block. The single transmission length means that the original storage module divides the original data into multiple data segments according to the single transmission length.

In the embodiment of the present application, the first check value in the unit data block is acquired, the second check value of the previous unit data block is used as the check reference value, and the check value is based on the data fragment sum of the unit data block. The reference value calculates the second check value of the unit data block, while ensuring that the data fragment transmission of the unit data block is complete and correct, the check result of the previous unit data block is verified again, and the data transmission is improved. integrity and reliability.

The recovery address is calculated by the received length of the original data and the initial storage address, and the storage location of the data segment of the unit data block is determined, which is convenient for searching and extracting the stored data, and at the same time, it is convenient to compare the length of the stored data and the original data when the transmission is completed, Confirm that the data transfer is complete. When the first check value matches the second check value, store the data segment in the unit data block according to the restoration address of the destination storage module, and output a transmission error notification if they do not match , allowing the original storage module to retransmit the unit data block, which further improves the reliability of data transmission.
