Research On Precision Irrigation Control System Based On Internet Of Things And Architecture

The shortage of water resources is the basic characteristic of our country,per capita water resources is less than the global average of 25%,and our country is a large agricultural country,is in great demand for agricultural irrigation water,but also in agricultural water due to poor irrigation techniques caused extremely serious waste water.With the development of information technology and Internet of things technology,the application of agricultural irrigation water technology ushered in a new starting point.In this development trend,experts and scholars from various countries are actively applying the new control algorithm and computer technology to agricultural irrigation,in order to save water resources as much as possible and improve the utilization rate of water resources.This paper concentrates on data acquisition,single field power supply inconvenience,communication quality is not stable,the design and implementation of the system,the system includes hardware design and software development of the two part,the hardware system mainly includes the ZigBee wireless node part,software development is the coordinator and routing node and host computer to write.The system uses real-time monitoring of the plant growth environment,temperature humidity sensor and light and moisture,through the ZigBee wireless network,the real-time data uploaded to the host computer,then the computer system according to the different plant required environmental monitoring data of plant growth threshold and adaptive control of the electromagnetic valve,to achieve precise irrigation.After a series of tests,such as point to point communication,antenna height,system barrier free operation,multi hop network,valve reliability and weather conditions,the reliability of the system is verified.After a series of reliability test and the successful application in the Agricultural College of Liaocheng University No.2 in a greenhouse,the experiment results show that the design of the sensor deployment scheme can accurately collect soil moisture,temperature and light moisture,and through the network transmission is reliable,the soil moisture content is uploaded to the PC in the irrigation area,it can to monitor the wholeirrigation area information.According to the optimum soil moisture content of different plants,different thresholds are set to make the plant in the most favorable growth environment,and achieve the purpose of energy saving and water saving.
