| Abstract: |
| A network measuring and control device is designed by using DSP(Digital Signal Pro-cessor) chip ADSP - 21992 and Ethernet control chip CS8900A. The configurable and modularized design and its implementation scheme are discussed,and the basic principles and features of its hardware and software designs are introduced. The implementations of fast Fourier transform algorithm in DSP's kernel and UDP/ IP protocol in DSP are emphasized. With its high precise and real-time measuring unit,the device designed is flexible,reliable and expandable,which can be used in substation monitoring systems. |
