摘要
主要介绍利用变频调速控制系统,实现模拟降雨系统对不同降雨量要求的自动调节功能.解决了原手动系统对降雨量大小变化时流量调节阀和管道安全性的问题.该系统的特点是:克服了径流小区进行定位观测耗时费力的缺点,缩短试验周期,加速雨水入渗规律和土壤侵蚀规律的研究进程,对水土保持以及水资源科学利用具有相当重要的意义.
This paper introduces the realization of a automatic adjustment function according to simulated rainfall system requirements using frequency control system.The system has solved a kind of safety problem when the original manual system changes the size of the rainfall flow control valve and pipeline.And has some features：overcoming some shortcomings of the observed runoff time-consuming locating defects,shortening the test cycle,speeding up the research process of the principles of the rainwater infiltration and soil erosion,which have an important scientific significance on soil conservation and water resource use.
