一种先进实用的单片微型计算机控制的泥水采样器研制

Study on An Advanced and practical Mud-water Sampler Controlled by Single-slice Microcomputer

为研究天然降雨对土壤侵蚀的规律,研制了两套用单片微型计算机控制的泥水采样器,以采集人工降雨条件下块田中的地表泥水径流。用于测定径流中的泥沙含量。文章介绍了泥水采样器各部分结构及工作原理和总的结构及功能。泥水采样器的单片微型计算机控制系统,表现出其较单板机等其它类型微机的优点。并绘出控制系统的软、硬件框图。采样器已经多次实验.运行可靠,采样量准确、精度高,采样频率灵活可调,其性能完全满足现场高水平科研及生产的需要。

To study the law of natural rainfall on soil erosion, we developed two sets of mud-water sampler controlled by single-slice microcomputer, the sampler was utilized to collect surface runoff on the farm under artificial rainfall condition,and to determine silt content in runoff. The artical has introduced the structure of each part, working principle, function of mud-water sampler. Control system of mud-water sampler was better than that of single-broad computer and their type microcomputers, in addition,sketch map of soft and hard wares controlling systems were mapping. The mud-water sampler has been tested for many times in laboratory,it works nomally,sample accurately and elastically,and has high accuracy. It may meet the needs enquire of production and high lever scientific research.
