Research And Design The Monitoring System Of Mushroom Greenhouse Based On Wireless Sensor Network

In order to realize edible fungi annualized and Industrialized,and to improve the quality and output,it's necessary to artificially regulate the growth of edible fungi.A greenhouse wireless sensor network monitoring system for monitoring the mushrooms' production in the southern mountain region of Chenzhou is designed in this thesis by using ZigBee wireless communication technology,scm control technique and LabVIEW remote virtual instrument technology in the light of harsh production conditions of edible fungi.The system can effectively improve and manage the growth,quality and output of mushrooms.After the analysis of mushroom growing environment,the overall design scheme of the system is determined,select hardware and design the hardware and software.For the important paraments of mushroom growing environment,such as temperature,humidity and carbon dioxide.when the system is started,the parameter data can be collected through the sensor,then they are dealt through STM32F103C8T6 singlechip,after that,they will be sent to upper computer by Zig Bee wireless sensor networks,at the same time,that the collected data are compared with the system default values,then produces a signal controlling actuator to achieve the regulation purpose of growth environment parameter.The edible mushroom shed growth environment is a system of multivariate,nonlinear,time-varying,strong coupling characteristics of temperature and humidity,in the control of algorithm,combining fuzzy logic control theory and the principle of decoupling,designed temperature and humidity fuzzy decoupling controller,and used MATLAB/Simulink for the fuzzy logic control system to simulation.The simulation results show that the algorithm can meet the requirement of system.The building of thehost computer system using LabVIEW virtual instrument with field data display,historical data query,alarm settings and other functions,and the design of remote control using the LabVIEW built-in Web server,so that the operator can real-time control and field observation in field even if the operator is not on the spot.Through many systems of calibration and test,the results show that the system is reliable,and it plays an important role in promoting the production of the anniversary and information of the edible mushroom.
