Description
Technical Field
The invention relates to the technical field of electric energy meters, in particular to a method for retrieving the daily time period meter rate of an electric energy meter.
Background
The multi-rate electric energy meter is also called time-sharing metering electric energy meter, and is an electric energy meter which respectively meters the electricity consumption condition of users according to different time periods. According to the size of the power load, a plurality of different time intervals can be set, the power supply department carries out different electricity prices on the electricity consumption in different time intervals, and the economic means encourages users to actively take the measures of avoiding peaks and filling valleys, so that the power load curve is slowed down, the utilization rate of the power generation equipment is improved, and unsafe factors caused by too large change of the load curve are reduced.
A day time table is usually preset in an MCU of an existing electric energy meter, as shown in fig. 1, each day time table includes start times of a plurality of time periods, that is, a first time of the day time table is a start time T of a first time period1The second is the starting time T of the second period2… and so on, the Nth is the start time T of the Nth periodnThe N +1 th is the start time T of the N +1 th periodn+1And the starting time T of the Nth periodnA start time T less than the N +1 th periodn+1The current time T and the starting time of each time period of the day time period table are sequentially compared to search the current rate to be used, and the specific search method is as follows: obtaining the starting time T of the Nth time periodnAnd a start time T of the N +1 th periodn+1Judgment of Tn (the same day)≤T<Tn +1 (the day)Is there any? T is a unit ofn (the same day)、Tn +1 (the day)All the time of the day, if yes, the current rate F to be used is searchedNAnd if not, continuing to inquire the next item of the time-of-day table. In practice, it is sometimes desirable that the time period corresponding to some rates is not on the same day, for example, it is desirable that the time period corresponding to some rates is 17:00(the same day)-1:00(the following day)Then in the time of day table, the start time of the corresponding Nth period is 17:00, thThe initial time of the N +1 time interval is 1:00, so that the initial time of the Nth time interval is greater than the initial time of the N +1 time interval, which is called as time-of-day table disorder, the disorder generally appears in the last two time intervals, and the current rate to be used cannot be accurately retrieved when the time-of-day table disorder is carried out by adopting the conventional electric energy meter time-of-day table rate retrieval method.
