Research on efficient operation of electrical control automation system based on intelligent frequency conversion regulation in agricultural water-saving irrigation

Abstract

In the context of the promotion of the concept of sustainable development, how to improve the utilization of water resources on the basis of limited natural resources to promote the efficiency of agricultural production and economic benefits, etc. is a hot issue of concern at present. In this study, a PID intelligent frequency control controller is selected to design the constant pressure water supply module of agricultural water-saving irrigation system. Then based on the air temperature and humidity and soil moisture sensors to design the environmental information acquisition module of the system, and finally combined with the design of intelligent frequency conversion agricultural water-saving irrigation control system. The results of empirical analysis show that the water consumption and energy cost of intelligent frequency conversion irrigation technology in cotton crop irrigation are much lower than that of small flow irrigation and traditional irrigation methods. It was also found that the output of cotton crop (5562.36 kg/ and 5629.35 kg/) was significantly higher under this irrigation technology and the average net income per hectare of output was significantly higher than the other two irrigation methods. The automatic irrigation control system designed in this paper based on intelligent frequency conversion technology greatly improves the irrigation efficiency, realizes the efficient use of water resources and high yield quality of crops, and facilitates the dynamic monitoring and management of agricultural irrigation process.
