Plug-in Card Design of DSP High-accuracy Electrity Measuring System Based on PCI Bus

摘要：

This paper is based on the research of high-accuracy electrity measurement. It detailedly introduces a design method of plug-in card of DSP high-accuracy electrity measurement based on PCI bus and operating principle. The plug-in card can measure the parameters of AC voltage or AC current signal, such as amplitude, frequency, phase, power and etc., and process the signal with high-accuracy. The accuracy index can reach 0.02％. The paper analyzes and researches the choice and characteristic of device and influence on improving system measuring accuracy, shows the circuit schematic diagram. The paper also gives a brief introduction about the use and control technology of the plug-in card.
