Detailed Description

Referring to fig. 1, the main method steps of the embodiment of the present invention are: s100, the intelligent card COS is electrified and reset, the state configuration is checked, and a post-download mode is entered; s200, remotely downloading a corresponding updating data packet for updating, wherein the data source of the updating data packet is an engineering hex file; and S300, after the updating is finished, switching to a normal working mode.

In some embodiments of the invention, referring to fig. 2, the state configuration comprises: a state flag bit indicating that the updating content exists and state flag content indicating whether the intelligent card completes the updating. After the intelligent card COS is electrified and reset, the state marking bit is firstly checked, and whether the updated content exists is judged. In this embodiment, the status flag is not null, i.e., it indicates that there is an update. If the updated content exists, the status flag content is further checked to determine whether the smart card has completed updating. And only when the updating content exists and the intelligent card is not updated, the intelligent card COS enters a post-downloading mode, otherwise, the intelligent card COS is switched to a normal working mode, and a normal working process is started. It will be appreciated that the enabling of the post-COS download update of the smart card may also be performed in other ways, such as a non-repeating sequence of numbers, indicating that there is update content only if the number of the smart card is not equal to the number obtained remotely.

In some embodiments of the present invention, referring to fig. 3, S200 comprises: s210, remotely downloading a corresponding updating data packet, performing data check on the updating data packet, and judging whether the updating data packet is normally downloaded; s220, if the downloading is wrong, deleting the update data packet, and entering the normal working mode after exiting the downloading mode; and S230, if the download data packet is normal, the corresponding content is further provided. In the embodiment of the present invention, whether the downloaded data is correct is determined through CRC check, and it can be understood that whether the downloaded data is correct may also be determined through other check methods. And in the updating process, if the abnormal condition occurs, the mode returns to the post-downloading state mode, so that the updated function can be normally used. And when the updating is normal, modifying the corresponding state mark content, finishing the updating, and switching to a normal working mode to prevent repeated updating.

In some embodiments of the invention, the update package construction process is described with reference to fig. 4 and 5. Firstly, the smart card COS acquires an engineering hex file and explains the file content. If the explanation is wrong, stopping the construction; if the interpretation is normal, data normalization is performed on the interpreted content. And if the standardization is successful, the construction can be completed, and if the standardization is failed, the construction is stopped. It will be appreciated that for builds that stop after failure, the problem is left to be verified and modified before the build is performed again until the build is successful. The detailed process of data normalization is shown in fig. 5, firstly, the line number of the interpretation content is counted, each line of data is packaged by taking a fixed size 10K as a block, and the last block of data is filled with 0 to keep the size of the last block of data to be a multiple of the preset value 8. In this embodiment, after all data are processed, the calculation of the CRC check value is also included. When other verification methods are used for the correct detection of the downloaded update package data, it is understood that the construction of the update package data also includes the calculation of the corresponding contents.

In some embodiments of the invention, the system includes 3 modules: a data packet constructing module 100, a status checking module 200 and a post-download updating module 300. The data package building module 100 is configured to build an update data package according to the engineering he x file; a state checking module 200, configured to check a state configuration, and determine whether a post-download mode needs to be entered; and a post-download updating module 300, configured to download and update the update data package.

In an embodiment of the present invention, the post-download update module 300 includes a download module 310 and an update module 320. A downloading module 310, configured to download a corresponding update data packet and check whether the downloaded data is normal; and an update module 320, configured to update the content of the update data packet and check whether the update is normal.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
