Design of Substation Data Collector Dedicated Line MODEM
摘要
Abstract
The traditional transformer substation'data acquisition line MODEM design is usually implemented by a dedicated FSK modem chip. Although the system has good reliability,the introduction of proprietary chips will inevitably lead to higher hard?ware design costs and technical monopoly and other issues. In order to solve these problems,a dedicated MODEM for substation da?ta acquisition based on Single-Chip Microcomputer is designed. A simple and effective FSK modulation and demodulation circuit is designed by using discrete components and combined with the FSK modulation and demodulation algorithm,the design of the dedi?cated MODEM for substation data acquisition is realized. The experimental results show that the hardware circuit and the effective?ness of the algorithm are verified,the hardware circuit is simplified,and the cost performance of the dedicated MODEM is im?proved,which provides guidance for engineering practice.关键词
