泥沙模型试验测控系统

CONTROL AND MEASUREMENT SYSTEM OF THE SEDIMENTATION MODEL TEST

本文介绍了成功地应用于国家“八五”重点科技攻关项目——三峡工程回水变动区涪陵河段泥沙模型试验的测控系统，简述了对模型试验进口的含沙量、流量和泥沙颗粒级配的控制原理和方法，重点介绍了微机尾水位自动控制以及流速、水位和波浪的多点同步采集与处理系统。

This paper introduces a control and measurement system which is used successfully for the model test of the Three Groge Project (in the backwater jone).This paper presents the operating principle and application of a synthetic measurement system for the automatic monitoring of sediment concentration,controlling of discharge and analyzing of sediment grain size,which are installed at the inlet of the model.It also presents a microcomputer control system for water level automatic control and for data,which are water level,wave height and flow velocity during model test,acquisition and processing in multipoints.
