水位是水利建设、防汛抗旱斗争的重要依据,是掌握水文情报和进行水文预报的依据。水位可用来推算其它水文数据如流量以及用来确定和控制闸门的开启和关闭等,因此水位是水利、水文等部门一项重要测量项目。本文介绍用微机控制水位测量的一种方法,这种方法具有多方面的优点。可用一机控制多点水位数据的采集;可以进行实时和任意定时测量;可以实现水位数据的远传和自动测试及自动打印记录;测量精确度高,可精确到1～5mm。
Water level is an important basis for water conservancy construction and flood control and drought fighting. It is the basis for grasping hydrological information and hydrological forecasting. The water level can be used to calculate other hydrological data such as flow rate and to determine and control the opening and closing of the gate. Therefore, the water level is an important measure in water conservancy and hydrology departments. This article describes a computer-controlled water level measurement method, this method has many advantages. Can use a machine to control multi-point water level data acquisition; can be real-time and any timing measurement; can achieve remote and automatic test water level data and automatic print records; measurement accuracy, accurate to 1 ~ 5mm.
