摘　　要：针对目前有源电力滤波器(APF)控制系统数据采集实时性不高,数据传输量有限的问题,设计了基于Lw IP的APF实时数据采集监控系统。文中详细介绍了系统下位机与上位机之间数据传输的时序控制,包括DSP数据组织传输,ARM数据接收调度以及上位机数据接收与下发等软件功能的实现。同时系统还实现了APF运行时通过上位机设置控制参数的功能。通过实验,验证了系统控制参数下发以及32 k Hz采样频率下15个数据实时更新的可行性与有效性。In view of the problem that the real-time data acquisition of APF( active power filter) control system is not high and the amount of data transmission is limited,the real-time data acquisition and monitoring system for APF based on LWIP is designed. This paper introduces the timing-sequence control of data transmission between upper and lower computer in detail,including the software functions for data organization and transmission of DSP,data receiving and dispatching of ARM,data receiving and transmission of the upper computer and so on. At the same time,the system also introduces the function of setting new control parameters by the host computer when APF is running. The feasibility and effectiveness of the system control parameters transmission and 15 real-time data updating under 32 k Hz sampling frequency were verified through experiments.
