Abstract

Agricultural irrigation is a very important link in agricultural production, but in the current situation of water shortage, reasonable control of agricultural water supply can not only achieve the purpose of irrigation, but also save water resources to the maximum extent. Therefore, this paper studies the agricultural water supply control system and its related circuits. According to the actual situation of agricultural irrigation, based on the nine-point controller in logic control, a control system of agricultural water supply based on nine-point controller is designed, and also the corresponding control circuit. The control system is verified by experiments. The results show that the control system circuit can meet the operation requirements under extreme conditions and has high stability. The experimental results of the control system show that the whole control system is obviously superior to the traditional PID control system, while the actual application results show that the whole control system has a good response and can control the water supply system in real time according to the actual situation of agricultural irrigation.

农业灌溉是农业生产中一个非常重要的步骤，但是在水资源逐渐短缺的今天，合理的控制农业供水既可以达到灌溉的目的，同时也能够尽可能的节约水资源，因此这里对农业供水系统中的控制系统及其相关电路进行研究。本研究根据农业灌溉的实际情况，以逻辑控制中的九点控制器为基础，设计了一个基于九点控制器的农业供水控制系统，并对其相应的控制电路进行了设计。然后通过实验的方式对该控制系统进行验证，验证结果表明控制系统的电路能够适应极端条件的运行需求，有较高的运行稳定性。而对控制系统的实验结果则证明了整个控制系统明显优于传统的PID控制系统，而实际的应用效果则表明整个控制系统具有良好的响应性，能够根据农业灌溉的实际情况对供水系统进行实时的控制
