【摘要】：為了解決傳統(tǒng)土壤界限含水率檢測中存在的需人工現(xiàn)場操作、耗時久、數(shù)據(jù)采集困難、數(shù)據(jù)傳輸實時性差等問題,設(shè)計了一種土壤界限含水率自動檢測系統(tǒng)。該系統(tǒng)以西門子S7-200PLC為控制核心,由傳送帶、正方體容器、攪拌容器、電子秤、抹平系統(tǒng)、圓錐儀和加熱箱等組成,使用MCGS組態(tài)軟件進行數(shù)據(jù)監(jiān)控,并采用采樣烘干法測定含水率,液-塑限聯(lián)合測定法測定液、塑性指數(shù)。實際應(yīng)用中,該系統(tǒng)能夠完成自動攪拌、多組數(shù)據(jù)同時測定和數(shù)據(jù)實時傳送,基于含水率和液、塑性指數(shù)實現(xiàn)土體的分類以及地基土承載力的估算。該系統(tǒng)具有自動化程度高、操作簡單及成本低廉的特點,能夠廣泛應(yīng)用于各種土壤界限含水率的測定,對農(nóng)業(yè)工程的設(shè)計和實施具有一定的參考價值。
[Abstract]:In order to solve the problems existing in traditional soil boundary moisture content detection, such as long time consuming, difficult data acquisition and poor real-time data transmission, a soil boundary moisture content automatic detection system was designed. The system is composed of conveyor belt, cube container, agitation container, electronic scale, flatting system, conical instrument and heating box, and uses MCGS configuration software to monitor the data. The moisture content was measured by sampling drying method, and the plastic index was determined by the combined method of liquid and plastic limit. In practical application, the system can realize automatic mixing, simultaneous measurement and real-time transmission of multiple sets of data, classification of soil mass and estimation of bearing capacity of foundation soil based on moisture content and liquid and plastic index. The system has the characteristics of high automation, simple operation and low cost. It can be widely used in the determination of soil moisture content, and has certain reference value for the design and implementation of agricultural engineering.
