Problems solved by technology

[0003] 1. Considering the low cost, the use of low-priced unknown capacitors cannot ensure enough time to store power-down data
[0004] 2. There is not enough margin. Because many electric energy meters use electrolytic capacitors, the error is 20%. The time for electricity to store data is greatly reduced
[0005] 3. The use of supercapacitors is derated. Some electric energy meters use supercapacitors in the design circuit. In order to make the life of the supercapacitors conform to the double 85 design, the method of reducing the voltage and reducing the charging c

Embodiment Construction

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0051] In view of the fact that the existing technology cannot accurately simulate the charging and discharging control of the capacitor, nor can it simulate the program problem of the electric meter caused by the accidental power failure during the operation of the FLASH, the embodiment of the present invention provides a simulation method based on the power-off data storage of the electric energy meter. Effectively evaluate whether the power-off data stored in t

Abstract

The invention provides a simulation method and system based on electric energy meter power-down data storage. The simulation method includes: according to preset capacitance capacity, preset load current and preset voltage amplitude, calculating power-down time, and generating simulation waveform; outputting the simulation waveform to an electric energy meter, and receiving and storing power-downdata fed back by the electric energy meter, wherein the power-down data are generated by the electric energy meter; judging whether the power-down data are complete or not; if not, increasing power-down time. By the simulation method and system, whether the power-down data stored by the electric energy meter are complete or not can be evaluated effectively.
