Design And Realization Of Rice Automatic Irrigation System

Rice is the main crop in our country,and rice irrigation is a very important link to determine the growth and yield of rice.At present,rice irrigation in our country depends on the daily experience of farmers,without specific data support and reference,so the ratio of water resources to water distribution required by rice is unreasonable.Based on the measured data and expert experience,this study uses the fuzzy control theory to establish the irrigation prediction model,input the soil moisture,humidity change rate,output the irrigation time,and implement the precision automatic irrigation according to the different requirements of the soil moisture in each stage of rice growth.This research includes two parts: hardware and software.The hardware part,which is composed of sensors,collects the soil moisture,temperature and illuminance in the rice planting area in real time,realizes the real-time recording and processing of the relevant parameters that play a key role in the rice yield,and uploads them to the server through ZigBee network,taking the rice soil moisture as the control quantity,when the measured rice soil moisture is less than the set threshold,the corresponding irrigation type is implemented.In the software part,sensors are used to collect the environmental factors of rice growth in real time.Through wireless communication technology,the collected data is transmitted to the upper computer,and automatic control technology is applied to issue instructions to the single-chip microcomputer for automatic irrigation.The system is developed with C# and B/S system structure.The function modules include planting management,irrigation control,data report and system setting.The purpose of this study is to reduce the cost of irrigation and the workload of farmers,so as to promote rice yield,monitor rice growth environment and provide scientific basis for subsequent irrigation.It can satisfy the rice irrigation project of small and medium-sized farmers,farms and areas,and the data collection is convenient,fast and real-time,so it has the value of popularization and application.
