With digital informatization in the rapid development of all walks of life, industrial system of informatization, digital will also e the future trend of development. Especially in the narrow space when operating, often face many functions, sizes, different range instrument panel. These instrument panel not only occupy a space, and not enough intuitive, easy to cause the working staff of the incorrect operation or reaction lag, give operating cause unnecessary trouble. So using AC frequency and voltage measurement technology, design the voltage frequency monitoring system, may simplify system operation space, improve work efficiency.
This design taking single puter AT89C52 as a bining the periphery signal to enlarge and the shaping circuit, through to the output waveforms of the count and the simulated voltage sampling, the quantitative get ac frequency and voltage the digital quantity. These data are sent to the puter by a series port and visual display,realizing the monitoring of the frequency and voltage. Design is simple in structure, measurement error small, has high practical value. Keywords:single puter;frequency;voltage;sampling;AT89C52;AD0809; 目录
