Data Supplement Settlement Method for Electric Energy Meter

Abstract

The invention discloses a data supplementation and settlement method for an electric energy meter. The data supplementation and settlement method comprises the steps that monthly valid settlement daysare arranged reversely; the year and month of current electrifying time serve as the year and month of a current supplementation and settlement node; the year and month of the current supplementationand settlement node and the year and month of current electrifying time are sequentially combined to obtain the current supplementation and settlement node; electric energy data of the current supplementation and settlement node is supplemented and settled; the month of the current supplementation and settlement node is ahead a month, and the year and month of the current electrifying time are updated; the steps are repeated till the number of current supplementation and settlement nodes reaches a set value, data supplementation and settlement of the electric energy meter is completed. The data supplementation and settlement of the electric energy meter performed in a reverse data supplementation and settlement mode according to the data supplementation and settlement method, so that allsupplementation and settlement time points can be found only by traversing the number of set supplementation and settlement nodes, the power consumption of the electric energy meter during power failure is not affected, and the operation is not needed that the electric energy meter is awakened in the low-power-consumption sleeping mode of power supply of a battery after power failure in a timed way.

Description

technical field [0001] The invention specifically relates to a data supplement settlement method for an electric energy meter. Background technique [0002] With the development of national economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source in people's production and life, bringing endless convenience to people's production and life. As the only component for measuring electric energy in the power system, the energy meter is self-evident in its importance and reliability. [0003] The metering and billing of electricity is the most important function of the energy meter. The energy meter settles and transfers the user's electricity every month. Monthly electricity settlement is an important basis for billing and deduction of electric energy meters. The electric energy meter performs electricity settlement and transfer on the settlement day set by the user, and the system performs dedu...

Problems solved by technology

[0010] The defect of this scheme is: the longer the power-off time, the more settlement points between the power-off time and the power-on time, and it is necessary to traverse from the power-off time to the power-on time and find out each valid settlement point during the period The longer the time is, and if the effective settlement points between the power-off time and the power-on time are greater than 12, each time the nearest supplementary settlement time point is found, the earliest supplementary settlement time point must be deleted to ensure that the final settlement point is found The 12 supplementary settlement time points are the last 12 supplementary settlement time points;

[0012] Although this solution will not make the power-on time longer to find all the compensation settlement points due to the longer power-off time, but if the battery of the energy meter itself is out of power or undervoltage, the MCU will not be in a low power consumption state but Completely lose power, in this case, it will not be able to perform scheduled wake-up, and cannot complete the above work. At the same time, scheduled wake-up under low power consumption will increase the power consumption of the battery under low power consumption, which will cause the low-power battery to be exhausted earlier
