Problems solved by technology
[0004] At present, the smart meter settlement method has the following technical problems: for the supplementary settlement, only the impact of power failure, school time, and daylight saving time on the supplementary settlement are considered, but the impact of the combined situation on the supplementary settlement is not considered, so that the supplementary settlement The result is not accurate enough

Embodiment
[0062] A smart meter settlement method, it comprises the following steps:
[0063] (1) The meter automatically judges whether a power failure occurs, or a time callback occurs, or an asynchronous settlement trigger command is received;
[0064] If power failure occurs, then enter step (2);
[0065] If time callback occurs, then enter step (7);
[0066] If an asynchronous settlement trigger instruction is received, proceed to step (11);
[0067] If none of the above three situations occurs, return to step (1) to continue judging;
[0068] (2) Judging whether one or more synchronous settlement periods are crossed during the power-off period;
[0069] If not, do not make supplementary settlement, and return to step (1);
[0070] If yes, go to step (3)
[0071] (3) Determine whether to enter or exit daylight saving time during power failure;
[0072] If entering daylight saving time during power-off, then enter step (4);
[0073] If exit daylight saving time during power-of...

A billing method for smart electric meters includes the following steps: (1) an electric meter automatically judges whether there is power failure; (2) whether the power failure period spans one or more synchronous billing cycles is judged; (3) whether the power failure period enters or exits from the summer time is judged, the method goes to step (4) if the power failure period enters the summertime, the method goes to step (5) if the power failure period exits from the summer time, and the method goes to step (6) if the power failure period neither enters nor exits from the summer time; (4)the relationship between the time of the first synchronous billing point in the power failure period and the entry time of the summer time is judged; (5) the relationship between the time of the first synchronous billing point in the power failure period and the exit time of the summer time is judged; and (6) supplemented billing is carried out for the first synchronous billing point in the powerfailure period. Through the billing method for smart electric meters, a reliable and accurate supplemented billing result can still be obtained under the conditions as follows: the power failure period enters the summer time, the power failure period exits from the summer time, and the power failure period neither enters nor exits from the summer time.
Description
technical field [0001] The invention relates to the technical field of electric meters, in particular to a settlement method for an intelligent electric meter. Background technique [0002] Smart meters are one of the basic equipment for smart grid data collection. They can realize online monitoring of metering devices and real-time collection of information such as user load, electricity, and voltage, and are the basis for information integration, analysis optimization, and information presentation. Settlement is an important function of smart meters, which can store important data such as electricity demand at a specific time in the external EEPROM, which is used to calculate electricity charges and determine the highest demand of power consumers, which is helpful for reducing power generation costs and planning electricity consumption. important meaning. [0003] Smart meter settlement includes three methods: synchronous settlement, asynchronous settlement, and supplemen...
