微机应用于河工模型试验

THE APPLICATION OF MICROCOMPUTER IN RIVER MODEL TEST

本文介绍了以APPLE-Ⅱ微机和以IBM-PC微机为核心部件的水位自动控制和流速、水位数据采集与处理系统以及该系统在河工模型试验中的应用。系统运行时,完全由主程序自动控制给定的边界水位,而后对模型中拟测量的多点水位、流速进行集中采集与处理,列表打印出一系列数据结果,并绘出断面流速分布图和水面线图形。

This paper introduces the complex system for water level automatic control and for data acquisition and processing of velocity and level in river model tests. The Apple Ⅱ or IBM PC microcomputer is used as the core part of tire system. It is operated automatically by main program. First, the boundary water level is controolled by the system, then data acquisition and processing of water level and velocity in the river model are carried out, and the list is printed, and finally the figures are drawn.
