摘要：This study designs a single-phase food measurement circuit for food system users. The circuit adopts a high-precision single-phase energy metering chip ADE7755 produced by the United States ADI company for the acquisition of the electrical energy and uses the high-performance SCM AT89C51 as a whole control center of electrical acquisition circuits. The working principle schematic of the single-phase energy metering chip circuit, the diagram of the components of the entire energy metering circuit and the software flow chart are introduced in study. At last, the test situations is introduced, the test results are analyzed and compared, the test showed that the energy metering circuit has the high precision.
