Description
Technical Field
The invention relates to the technical field of multi-rate electric meters, in particular to an illegal judging and processing method of rate and related parameters.
Background
The multi-rate electric energy meter is also called a time-of-use electric energy meter and a multi-rate meter, commonly called a peak-valley meter, and is a metering means provided for meeting the demand of peak-valley time-of-use electricity price in recent years. The method can respectively measure the power consumption of the peak, the valley and the flat section according to the preset division of the peak, the valley and the flat section, thereby adopting different electricity prices for the power consumption of different sections, exerting the adjusting function of the electricity prices, encouraging the electricity customers to adjust the electricity load, shifting the peak to fill the valley, reasonably using the power resources and fully mining the potential of the power generation, supply and utilization equipment.

Disclosure of Invention
The technical problem to be solved by the invention is as follows: the illegal judging and processing method of the rate and the related parameters, which can effectively ensure the rate to be accurately and reliably obtained, is provided.
The technical solution of the invention is as follows: an illegal judging and processing method for rate and related parameters is characterized in that: it comprises the following steps:
(1) automatically judging whether a rate setting instruction or a rate query instruction sent by an upper computer is received by an electric meter MCU, if the rate setting instruction is received, entering the step (3), if the rate query instruction is received, entering the step (2), and if the two instructions sent by the upper computer are not received, returning to the step (1) to continue judging;
(2) entering rate query through a table lookup method, if the corresponding rate can be found and the rate and related parameters in the current table are legal in the table lookup process, taking the queried rate as the current rate, comparing the current rate with the rate stored in the MCU of the electric meter at the previous moment, executing rate switching action only under the condition that the rates at the previous moment and the later moment are changed, and simultaneously returning to the current state stat which is successful; if any one of the corresponding rate or the rate and the related parameters in the table cannot be found to be illegal, taking the default rate as the current rate, comparing the current rate with the rate stored in the MCU of the electric meter at the previous moment, executing the rate switching action only under the condition that the rates at the previous and later moments are changed, and simultaneously returning to the current state stat which is an illegal type;
(3) and judging whether the data format of the rate and the related parameters in the rate setting instruction sent by the upper computer conforms to a protocol preset in the ammeter, if so, entering a current table to set the rate and the related parameters, and if not, failing to enter the current table to set the rate and the related parameters.
After the method is adopted, the invention has the following advantages:
when sending the rate query command at the upper level, the illegal judging and processing method of the rate and the related parameters can carry out illegal judgment on the rate and the related parameters in the table look-up process and give out corresponding processing schemes; when the upper computer sends the rate setting instruction, the rate and related parameters sent by the upper computer are judged illegally, and a corresponding processing scheme is given, so that the rate and phase parameters are judged illegally and the processing scheme is given no matter in the rate inquiry or rate setting process, so that illegal conditions occurring in the rate inquiry and rate setting process can be fed back and solved in time, and the rate can be ensured to be obtained accurately and reliably.
Preferably, in the step (1), the electric meter MCU further judges whether the timer reaches the automatic query time, if so, the step (2) is performed, and if the automatic query time does not reach and the rate setting instruction and the rate query instruction of the upper computer are not received, the step (1) is performed again to continue the judgment. The rate parameters can be actively and regularly inquired by the setting, and the reliability is higher.
Preferably, in the step (1), before the MCU of the electric meter automatically determines whether the rate setting instruction or the rate query instruction sent by the upper computer is received, the MCU of the electric meter automatically determines whether the standby form preset in the MCU is activated, if so, the standby form is used to replace the current form, and if not, the content of the current form is not changed. The setting can conveniently and uniformly and quickly change the data of the current form.
Preferably, the current table in step (2) includes a season table, a week table, a day table and a tariff table, the illegal type includes a season table query exception, a week table query exception, a day table query exception and a tariff table query exception, and the table lookup method includes the following steps:

When the rate is inquired, two different inquiry schemes are adopted according to whether the current date is a holiday or a common date, because the number of holidays is small, the daily schedule IDs are directly preset one by one through the MCU, only the daily schedule and the script table are inquired during inquiry, but the number of non-holidays is large, if the MCU is adopted, the number is very large, and therefore, the corresponding daily schedule IDs are obtained in a mode of additionally arranging the quaternary schedule and the weekly schedule in a matched manner, the memory space occupied by the daily schedule IDs of the non-holidays is small, and the daily schedule IDs are convenient to obtain; therefore, the rate can be rapidly inquired no matter whether the current time is a holiday or a non-holiday; in addition, the specific illegal type can be returned in the table look-up process, thereby being beneficial to quickly checking the illegal condition.
Preferably, in the table lookup method of step (2), in step (c), each of the week table IDs in the week table corresponds to a day table ID for each of monday to sunday. The setting can set different rates for Monday to Sunday, and the parameter setting is more flexible.
Preferably, the query exception of the quaternary table in step (2) includes one or more of a time series exception of the quaternary table and an exception of a date format of the quaternary table. The abnormity is common in the quaternary table and has larger influence, and the abnormity is checked, so that the reliability of rate inquiry can be improved.
