资 源 简 介

设计一种基于P89V51RD2的功率因数测量仪,采用光电隔离器和专用数码管驱动器。该测量仪是以增强型单片机P89V51RD2为核心,大大简化系统硬件设计。而软件部分采用模块化设计思想,采用中值滤波和小数补偿算法,实现功率因数的高精度测量。实验测试表明,该功率因数测量仪测量精度高,运行稳定可靠。

Abstract:
 A power-factor measurement instrument based on P89V51RD2is designed,which uses optical coupler and specific LED drive chip.The power factor measurement instrument uses P89V51RD2as a core of which greatly simplifies the system design.Furthermore,modularization software is developed in detail.The high precision power-factor measuring system is realized by the center value filter and fractional compensation algorithm.Experiments manifests that the power- factor measurement instrument is high precision,steady and reliable.
