Abstract

According to the problem that introduces the design of smart meters,which is based on ML610Q495 microcontroller and IDT90E23 measurement chip. This meter has the characteristics of wide range measuring and high accuracy RTC. In the range of 0.02A~100A current, the meter’s measuring accuracy is below ±0.2%, and in the range of -45 C~+85 C temperature the meter’s RTC accuracy is below ±0.1s/d. This design can meet all the requirements of the State Grid, China Southern Power Grid, and Neimenggu Power Grid, and the meters have passed the test.
