新型多功能土壤水分运动测试装置的测控系统研制

The Development of Measure and Control System in New Type of Multi-function Soil Water Moves Experiment System

介绍了用核技术法实现大型非饱和土壤水分运动的多功能自动测定装置及其计算机测控系统。重点介绍了该装置测控系统的硬、软件结构和设计思想。通过位置中断控制解决了二维测试空间单放射源多点自动测定的技术难点，为大型动力水文实验研究提供了先进的技术手段。

A new type of multi-function automatic measure system and its comPuter measure and control system which is used in soil unsaturation water moves with the technique method of nuclear is introducde. The structure of hardware and software as well as the design of measure and control system will be mainly introduced. Using posihon interrupt controlling, measuring several points in 2-D measure space automaically with the single radioactive source, which was the technique difficulty is solved. Using this method also offers advanced technique method for accelerating development in area of larg hydrology researeh.
