And the verification of the effective time of the code is to compare the effective time information contained in the operating system code with the current time, if the current time is not earlier than the effective time, the verification result of the effective time of the code can be judged to be passed, when the two verifications are passed, the verification result of the starting of the current operating system code can be judged to be passed, otherwise, the verification result of the starting is judged to be failed.
According to the preferred embodiment provided by this embodiment, the code correctness checking may be performed first, and the code validation time checking is triggered after the code correctness checking passes, and in this flow mode, it may be determined that the start check result passes as long as the result of the code validation time checking passes.

firstly, in response to an operating system upgrade instruction of the electric energy meter, the electric energy meter enters a system upgrade switching mode, and a target system code area is determined according to the operating state information of the electric energy meter, wherein the target system code area is one of the system code areas in a non-operating state, for example, the current electric energy meter runs operating system codes in a system code area BANK1, the BANK1 is the system code area in an operating state in the electric energy meter terminal, and the rest BANK2 is the system code area in a non-operating state.
After the target system code area finally stored in the operating system code file to be upgraded is determined, before the operating system code to be upgraded is stored in the target system code area, the operating system code to be upgraded can be stored in an off-chip system backup area, code correctness checking can be carried out in the system backup area, the operating system code to be upgraded is complete and safe, and then the operating system code to be upgraded is transferred into the on-chip target system code area BANK2 to be stored, when the checking result of the code effective time is passed, the operating system code running in the BANK1 is stopped, and the operating system code in the BANK2 is started, so that the currently running operating system code is switched into the operating system code to be upgraded.
