| Abstract: | In order to reduce the peak-to-valley supply of electric energy in a certain extent, Hall sensor measuring circuit, sampling circuit and signal processing unit were designed. It also includes the programs of power calculation display, power display and so on. The PC transmission section consists of max232 serial interface completing the time-sharing metering parameter setting. The theory calculation and final conclusion of experiment is fit for the meter＇s design and development index mark. The check accuracy can reach 2%. It is actory for civil use in reality. |
