Control Strategy And Realization Of Humidity In The Environmental Factors Of Edible Mushroom Cultivation

At present,the development of the edible fungus industry has gradually transitioned to automation and factory production.Pleurotus eryngii is one of the main products of the edible fungus base in the Great Wall of Pengyang,Ningxia.Due to the impact of local climatic conditions,the output is not ideal.At present,the humidity is still dominated by artificial regulation,which is not conducive to annual and factory production.In the control of mushroom shed environmental factors in Pengyang Edible Fungi Base in Ningxia,the temperature has been automatically regulated,but there are still some deficiencies in other aspects,mainly the existence of automatic control of humidity needs to be improved.This paper makes further research on the regulation of the humidity of Pleurotus eryngii.The purpose is to realize the integration of humidity control.The growth process of Pleurotus eryngii is very conmplicated.In the stage of hyphae growth,the humidity does not need to be controlled too much.However,during the fruiting period,the control of the humidity is very critical.If it is too low,the mushroom body will be chapped and may be too high.Inhibition of growth or occurrence of disease,therefore,this article is aimed at one of its growth stages as a research object.Firstly,the relevant humidity data was collected through the environmental factor collection platform in the mushroom shed,and then the data collected was processed through MATLAB programming and humidity modeling.Based on the model,the humidity control strategy was studied,mainly through the literature materials.Comparisons with field experiments verify the use of fuzzy PID control algorithms and simulations in simulink.The controller chooses Siemens S7 series PLC.The fuzzy PID algorithm is based on the combination of PLC and simulink.The key is to use the OPC TOOL toolbox in MATLAB.The fuzzy PID algorithm is modeled in simulink and the MATLAB and PLC are implemented through modules such as OPC read and OPC write.The communication and communication implementation process also requires PC Access SMART software.Finally,the moisture control interface of the mushroom shed was configured by Wincc.The system was designed with the use of the field as the goal,and the laboratory simulation was performed and verified.Finally,it is concluded that fuzzy PID can effectively regulate the humidity of Pengyang Pleurotus ostreatus in Ningxia.
