Intelligent Control Design of Irrigation Area Measurement and Control Gate Based on Internet of Things and PLC
In order to better meet the requirements of the irrigation system,an intelligent control system of irrigation district measuring and controlling gates based on the internet of things and PLC is proposed for the overflow characteristics of the open canal flat gates,with a view to achieving accurate control of the flow rate and thus the irrigation demand.The results of the study show that ZHOU Yi-qi,LI Hong and WU Li-xin flow rate flow coefficients are different for the matching of the system,the maximum relative error of ZHOU Yi-qi's formula under working condition 3 is 37.57%,while the error of LI Hong's formula floats at 20%and the relative error of the formula proposed by the study is only 4.16%.So the formula proposed by the study is more practical for the system.The results of the study provide a reference for the design of intelligent control system for measuring and controlling gates in irrigation areas.
