Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The core of the embodiment lies in that the refreshing process of the module data is automatically triggered through an instruction, and the step of downloading the data again by a client is omitted, so that the operation flow is simplified and the production time and the cost of the client are saved under the condition of improving the stability. The following describes implementation details of the method for improving the stability of the data module in the embodiment in detail, and the following only provides implementation details for easy understanding, and is not necessary to implement the present solution.
Fig. 1 shows a flow chart of a method 100 for improving the stability of a data module according to this embodiment.
Step 101: and after the module is powered on, starting a system boot item.
Step 102: searching whether a moving mark exists; the moving mark represents that the last moving operation is not completed, so that the moving step can be directly executed if the moving mark is searched, and the rest moving operations are completed.
Therefore, if there is a move flag, the step of moving the data is executed as shown in step 103.
If there is no move flag, then the method is started normally and waits for a move command from the controller, as shown in step 104.
Step 105: after receiving the move instruction, a move flag is added. The purpose of this step is to mark that the transfer operation has started, and if the module is powered off when the transfer has not been completed, the transfer operation can be directly continued without waiting for a transfer instruction after the module is powered on again, as described in the above steps 101 to 103.
Then, jump to step 103: executing the step of moving data.
In some embodiments, the move command is received through a universal serial bus interface (USB interface) or a universal asynchronous receiver/transmitter interface (UART interface).
Compared with the prior art, the method and the device have the advantages that the process of refreshing the data is triggered through the command, and the step of manually downloading the data by a client for refreshing is omitted, so that the operation flow is simplified, and the production time and the cost of the client are saved under the condition of improving the stability. In addition, the embodiment of the invention also considers the situation of power failure in the midway of refreshing the data, sets the moving mark aiming at the situation, searches the moving mark firstly after the module is powered on so as to judge whether to directly continue to execute the moving step, and further improves the efficiency of program operation.
The step of moving the data in step 103 is specifically shown in fig. 2, and referring to fig. 2, the step of moving the data includes:
step 201: the address of the data block which needs to be moved currently is obtained by querying the position mark P1.
Step 202: it is determined whether the temporary area has full backup data for the data block.
If the temporary area has the complete backup data of the data block, step 203 is executed: the backup data in the temporary area is written to the address.
If the temporary area does not have the complete backup data of the data block, execute step 204: the data blocks within the address are written to a temporary area to form backup data. After writing the data block to the temporary area, check information is added to ensure the correctness and detectability of the temporary area data, as shown in step 205.
Then, after the backup data is formed, it jumps to step 203: the backup data in the temporary area is written to the address marked by the location mark P1. Specifically, before writing the backup data in the temporary area to the address, the data in the address is erased.
After writing the backup data in the temporary area to the address, P1 is made P1+1 to move the position marker P1 to the next data block, as shown in step 206.
Then, in step 207, it is determined whether P1 is greater than the address of the last data block.
If P1 is less than or equal to the address of the last data block, the process returns to step 202 to perform a refresh operation on the next data block.
If P1 is greater than the address of the last block, indicating that all data has been moved, so step 208 is performed: erasing the moving mark to finish moving.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
