The Analysis Of The Ltchi Growth Environment Monitoring System Based On Soil Property Ddetection Technology

Since ancient times,litchi has always been one of the favorite tropical fruits.Therefore,in the provinces with suitable geographical conditions,litchi planting is often regarded as a major aspect of its economic development.In this paper,Nanshan litchi garden is selected as the research object,which is located in Shenzhen City,Guangdong Province.The growth rate of litchi is relatively slow in the early stage of planting.Therefore,in the early stage of planting,the growth environment of litchi should be monitored to provide high-quality environment for litchi as much as possible to ensure the early survival rate.In this paper,the growth environment of litchi will be monitored with the help of soil detection technology.Based on the analysis of litchi growth environment monitoring system based on soil property detection technology,this paper firstly studies the growth environment of litchi,and on this basis discusses the requirements of hardware and software of the monitoring system,and finally designs the overall scheme of the system.Then the hardware part of the system is studied,the hardware framework is designed,and osa-1w sensor is selected to collect soil temperature and humidity data,and the structure and circuit diagram of the sensor are analyzed.Then,the circuit diagram of soil p H data acquisition is analyzed,and the communication between p H acquisition module and AD7705,signal acquisition and related circuit diagram are studied.This paper discusses the design of the light sensor of the system,so the light has a great influence on the growth of litchi.Then,the Zig Bee wireless transmission module is studied,and the communication circuit between the upper computer and the lower computer is analyzed.At the same time,this paper also designs the software part of the system,selects Lab VIEW as the platform of system software development,and presents the implementation interface of the system.At last,the system was designed to monitor the soil moisture and the application of the system.The final soil testing data also showed the effectiveness of the study.
