| Abstract: | The paper introduces the structure and measuring principle of the ADE7757 chip,and suggests an electric energy measuring method based on ADE7757 and P87LPC764 microcontroller. The method can ensure that the power can be calculated by the input voltage and electric current value inside CMOS chip, and the measuring value of power and electric energy can be obtained through SCM calculating .The whole measurement is simple in circuit ,good in anti-jamming and precise in measurement because the voltage involved and electric current signals are digilized. |
