潮汐模拟系统的研制

Modelling system of tidal simulation

该系统根据要模拟的目标潮位曲线，利用微机计算出控制水池瞬时进出水量及尾门高度变化的时间信号，依此对多功能水池的尾门运行及进出水量进行实时控制和修正，以达到模拟目标潮位曲线的目的。使用表明，该系统自动化程度高，操作简单；不仅提高了试验精度，而且加快了试验的速度。

The height of rear gates in the multi-functional experimental basin,in which the gates form the basin wall,is able to be adjusted with a stepping motor. With the help of a microcomputer, the instantaneous water discharge and the gate elevating process are calculated according to the thin weir discharge formula to simulate the desired tidal waves in the basin. The tide level data in the basin are collected and compared with the desired value,and then be modified by the process of real-time-analysis. Thus various tidal waves are got to meet the experimental requirements.
