基于DSP和USB2．0的气固两相流测量系统设计

摘要

The accurate measurement of the gas-solid two-phase flow have important and realistic meaning in some areas in-cluding energy,chemical,environmental,meteorological,metal urgy and so on,and with the rapid development of science.lt's more and more important to get online measurement of the parameter continuously.This paper introduces gas-solid two-phase flow measurement system based on DSP and USB2.0,include data acquisition and calculation of microwave signals, andcommunicates with PC through USB,realized the real-time monitoring of gas-solid two-phase flow.%气固两相流参数的准确测量在包括能源、化工、环境、气象、冶金等领域都有着重要的现实意义，并且随着科学技术的迅速发展，在线、连续地对气力输送进行测量就变得越来越重要。介绍了基于DSP和USB2．0的气固两相流测量系统，对微波信号进行数据采集以及运算，并与上位机通过USB进行通信，实现气固两相流的实时监测。
