Problems solved by technology

However, in the process of calculating the remaining electricity, the impact of the ladder electricity price and tariff electricity price on the electricity consumption is ignored, and the calculated data has a large error, which will inevitably affect some user experience, especially those enterprises with large electricity consumption. For example, in cold chain factories or manufacturing enterprises, breakpoints caused by inaccurate remaining days of use will cause them considerable economic losses

Abstract

A method for calculating the remaining days of use of a prepaid electric meter is characterized in that: it comprises the following steps: (1) obtaining the rate electricity price F; (2) obtaining the ladder electricity price J K ; (3) Judging whether the record number M of the total forward active energy is less than or equal to the specified number B? If yes, the average power consumption in the past several days P=W 1 / M,W 1 is the total forward active power of the last record; if not, the average power consumption in the past several days P=(W 1 -W B+1 ) / B,W 1 is the total forward active energy recorded in the previous record, W B+1 It is the total forward active energy recorded in the previous B+1 item; (4) Calculate the amount D required to complete the current step K K =(A K -W 1 )*(J K +F); (5) Judgment D K Is it greater than the current remaining amount C of the meter K ? This method takes into account the step electricity price and the rate electricity price, so that the calculation result is more accurate.

Description

technical field [0001] The invention relates to the technical field of electric meters, in particular to a method for calculating the remaining days of use of a prepaid electric meter. Background technique [0002] The prepaid electricity meter solves the problem of difficulty in charging with the traditional electricity meter. The user recharges the ammeter in advance when using it, and when the balance is used up, the ammeter automatically switches on and the user cuts off the power. If users want to know when the power will be cut off, they need to invent a method to calculate the remaining days of use based on the balance, so that users can recharge in time to prevent power outages. [0003] The method commonly used at this stage to calculate the remaining days of use of prepaid electric meters is calculated by dividing the remaining electricity by the average electricity consumption in the past few days. However, in the process of calculating the remaining electricity...
