[0012] S06), after the server verifies the correctness of the downloaded software package, it sends software upgrade command through IEC104 communication; the client responds to the software upgrade command, closes the OTA connection, closes the IEC104 communication connection, and starts the upgrade;

[0013] S07), after the upgrade is completed, the client re-establishes the IEC104 communication connection, the server acquires the inherent parameters of the client including the software version number and compares them, and if the verification is passed, the software upgrade is completed.
