The Design Of Fuzzy PID Controller And Remote Monitoring System For Environmental Factors To The Growth Of Eringi

Eryngii growth has a strong dependence on the environment. And temperature, humidity, CO2concentration, light intensity are the four most important influencing factors. The factory cultivation, annual production of Eryngii requires two conditions:firstly, to konow well about the requirement of temperature, humidity, CO2concentration, light intensity in eryngii growth period; secondly, building Intelligent Greenhouse to control the growing environment of Eryngii strictly.Firstly, based on previous research on control strategy of Pleurotus growth and combined with experience of cultivating Pleurotus in the Southern Ningxia, a set of wireless remote monitoring system was developed, which is responsible for monitoring the temperature, humidity, CO2concentration in real-time in the Eryngii house, and monitoring data will be sent wirelessly to the upper computer and dynamicly display in the monitoring interface, which is developed by Kingview6.55.Greenhouse cultivation of Pleurotus eryngii environment system is a complex process with lag a nonlinear, time-varying, and it is difficult to establish the accurate model of system. Based on the temperature control has reached the expected goal, precise control of humidity on the growth of Pleurotus eryngii has become extremelyimportant, so the control of temperature and humidity needs intelligent and enrich the means of control. For this class is unable to obtain the accurate mathematical model of the system, this paper combines fuzzy control and PID control, a fuzzy PID controller is designed for humidifying equipment. Using the fuzzy theory to the parameters of PID are adjusted, the three parameters can adaptively adjust with the changes of the object, while not affecting the normal operation of the system, realize the precise control ofhumidity. Using the MATLAB Fuzzy Control Toolbox Fuzzy PID controller design, and Simulation of control algorithm in Simulink. The simulation results show that in the case of large disturbance, the systemcan quickly reach the environmental parameter, strong anti-interference ability,fast response and strong robustness, control system based on fuzzy PID algorithm is ideal for Pleurotus eryngii humidity inside greenhouse controleffect.Application microcontroller programming to achieve fuzzy PID control algorithm, using Proteus and Keil software development joint commissioning way to build a comprehensive co-simulation strategy for the next crew hardware circuits, software design, development PC software system.In summary, based on the need of industrial development of eryngii in southern Ningxia, a wireless remote monitoring and control system was designed. which can regulate the environment in the Pleurotus eryngii greenhouse. Design of humidity fuzzy PID controller which have instructive function for the development of local eryngii industry, and lay the foundation for the study of the wireless remote monitoring system.
