　　This paper expatiates power measurement system design ideas and specific design steps. According to the principle of single chip interface technology to measure power as the main design intent. Based on singlechip, and emphatically introduces the 51-series microcomputer in the system, and the important position of its periphery hardware circuit chip structure characteristics, functions and tube feet knowledge. Set measurement, display function at an organic whole, design is complete, structure is clear, simple operation. In this design, is used for circuit voltage and current separately, then after adc sampling, the simulation ADC0809 quantitative change for corresponding the digital quantity, utilize six unity of digital tube display voltage and power. This paper discusses the composition of the hardware circuit. Using single chip computer to complete the entire measurement circuit test control, data processing and display output.
