摘　　要：该实验装置依据水电场两者之间的相似性原理,模拟渗流场中的等水头线,并利用正交原则绘出渗流区的流网图,从而得到渗流场内任意点的各水力要素,达到水电比拟实验的目的。该装置主要由交流信号产生模块、A/D采样及显示模块、单片机控制模块、串口通信模块以及电源模块组成。利用单片机作为系统控制和数据处理核心,对加有交流电信号的实验容器中设定的6 4路探针进行信号采集,并对其进行实时显示。通过串口通信将所获数据发送给计算机,进行综合分析和处理得到实验容器中水的等电位线。The experimental device based on the principle of similarity between water and electric fields,to simulate water head isogram of seepage field,and make use of the orthogonality principle to draw the flow net map of seepage areas,can gain any point of the hydraulic elements in seepage field,so as to achieve the purpose of the experiment of water and electricity analogy.The device mainly consists of the AC signal generator module,A/D sampling and display module,single-chip microcomputer control module,serial communication module and power module.The use of single-chip microcomputer as a system controlling and data-processing core,has to gather the electrical signals form 64-channel probe in the experimental containers in which AC signals can be added,and display in real time.It will be obtained data and sent to the computer by the serial communication,making a comprehensive analysis and treatment to acquire equipotential lines in the experimental container of water.
