Check code generation method, data recovery method, medium and electronic equipment

Номер: CN116107800A
Принадлежит:

The invention belongs to the technical field of data recovery, and particularly relates to a check code generation method, a data recovery method, a medium and electronic equipment, and the method comprises the steps: S1, calculating first check data of source data through a CRC-16 algorithm; s2, calculating the source data by adopting a check algorithm of a bit lookup table mode to obtain second check data; s3, merging the first verification data and the second verification data to generate a final verification code; according to the check code generated by the check code generation method, the situation that the check code obtained through calculation of non-zero data is 0 can be effectively avoided, only half byte is added to the check code, and both accuracy and storage space are considered.

The invention belongs to the technical field of electronic circuits, and discloses a non-isolated alternating current sampling double-power calculation single-phase electric energy meter and method, and the method comprises the steps: S1, enabling a live wire current sampling circuit to collect the live wire current of alternating current by taking a zero line as a reference ground based on the characteristics of the alternating current, the null line current sampling circuit collects the null line current of the alternating current by taking a live wire as a reference ground; based on the alternating current characteristics, the dynamic voltage sampling circuit circularly collects the zero line voltage of the alternating current through the first sampling loop, and the second sampling loop collects the live line voltage of the alternating current. S2, the first data processing module calculates a first path of power of the alternating current based on the received zero line current and ...
