基于RISC-V的农田智能灌溉控制系统研究
Intelligent Irrigation Control System for Farmland Based on RISC-V
摘要
Abstract
In order to improve the water utilization efficiency of farmland irrigation and clarify the impact of different soil qualities on irrigation quantity,constructed a model based irrigation control system using RISC-V architecture chip.The system used GD32VF103VBT6 chip as the core MCU,including main controller,communication,sensors,irrigation cal-culation,safety operation and other functional modules.By quantifying the differences in water transport dynamics of dif-ferent types of soil and based on the proportion of sand,clay and other components in the soil,an irrigation quantity esti-mation model suitable for different soil textures was constructed.The system combined real-time soil moisture data ob-tained from soil moisture sensors to calculate the optimal irrigation amount for each round of irrigation,and controlled the opening time of electromagnetic valves in each irrigation area based on the irrigation amount to achieve automatic irriga-tion.This system had functions such as moisture measurement irrigation,remote control,integrated irrigation of water and fertilizer,and automatic rotation irrigation.The results showed that compared with traditional farmer experience irri-gation methods,this system can significantly reduce crop irrigation by 17.3％,but had a small impact on grain yield,only reducing by 0.16％;Compared with the soil moisture dynamic balance model,the irrigation amount of this system decreased by 9.2％and the yield increased by 0.19％.In summary,the research and application of this system can ef-fectively reduce farmland irrigation while ensuring stable crop yield,which is of great significance for the development of smart water-saving agriculture.关键词
