Description
Technical Field
The invention relates to the technical field of rate switching of electric equipment, in particular to a method for activating standby rate of electric equipment.
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, playing the role of adjusting the electricity prices, encouraging power customers to adjust the electricity load, shifting the peak to fill the valley, reasonably using the power resources and fully exploiting the potential of power generation, power supply and electric equipment.
Two different tariff schemes are generally arranged in the multi-tariff electric energy meter, so that the power bureau can switch between different seasons, the power price can be adjusted when the seasons change, and the power load can be better controlled. Since the electric energy meter can only operate in one scheme within a time period, if necessary, the switching of different rate schemes is realized through local or remote parameter setting. The IDIS (Interoperable Device Interface specifications) protocol provides that the content of the activated standby rate scheme replaces the content of the current rate scheme, and for the method for activating the standby rate scheme, the existing program usually adopts address pointer offset, namely the addresses of two sets of rate schemes are continuous, the standby rate scheme is activated through the initial address offset, but all parameters (more than or equal to four) need to be reset, the efficiency is low, and therefore, the method has certain limitation in use; if the standby rate scheme inside the electric energy meter is activated by the data relocation of the EEPROM, the data volume is large, the program resource occupies a large space, even causes the watchdog to reset, and has no practicability.
