Abstract
The research integration, automated, the multi-purpose modernized synthesis measuring instrument has become the modern science technological development highly the tendency. At present, the electronic technology, the computer technology progress by leaps and bounds, the article selects the STC89C51 monolithic integrated circuit chip to take the control core, through to exchanges the signal high speed sampling sensor's application, completes to electrical parameter and so on electricity voltage, electric current surveys, discusses based on monolithic integrated circuit's power and the power factor survey question, has given the practical metering circuit, uses piece of 89C51 to carry on the analysis, uses the metrical data which the RS-232 mailing address will gather to upload PC machine to realize the data analysis. And uses the software antijamming design in the hardware antijamming design basis, uses the software to adjust, the simplified circuit, enhances overall system's accuracy effectively.
