Research On Key Technologies For Edible Fungi Cultivation Monitoring System Based On The Internet Of Things

With the rise of the Internet of Things,relevant technologies such as sensors,monitoring,information transmission,data analysis,and environmental control.The combination of traditional agriculture and Internet of things has become the trend of modern agriculture.At present,the automated mushroom growing chamber has become the main production model of the edible fungus industry.With the development of automated mushroom house construction technology,monitoring the growth process and environment of edible fungus accurately has become a hot topic of research.The industrial production of edible fungi and the monitoring system of the growth process are the most representative intensive production models.Thanks to the factory and the popularity of mechanization production,the development of modern information technology and advanced sensor technology,advanced electronic instruments such as electronic camera,display controller equipment improvement,make the Internet of things technology in the direction of the industrialization,intensive development of agricultural production has played a great role in promoting,research and promotion of edible fungus plant automation and monitoring strategy edible fungus industry in our country in the future to precision has become a key link in the process of high value-added products and economic development.In the key variables of automation control of edible fungi is the control of environment variables,edible fungus environment generally includes the location of the various edible fungi of quality lighting brightness,light spectrum,illumination time,training environment air flow direction and flow velocity,concentration of oxygen,carbon dioxide in the air,all kinds of harmful gas concentration,air water vapor saturation,air temperature,soil moisture,soil temperature,soil EC and PH value,dissolved oxygen content of soil,and the concentration of metabolic wastes,and other variables in the soil.Control the external factors of growth of edible fungi on the growth situation has a key role,through the control of the growth of external factors,the growth of mycelia and fruit body can be in the best conditions to grow,can effectively improve the efficiency of agricultural production and economic profit.In this study,a wide range of species was selected,and the representative agaricus bisporus was used as the research object.The production index and environmental factors of agaricus bisporus were analyzed.Based on the characteristics of the growth process of agaricus bisporus,the overall structure of the automated production monitoring system for agaricus bisporus was determined.The concept of growth coverage of Agaricus bisporus was introduced.In order to monitor the growth process more accurately,an environmental control strategy was established and a monitoring scheme based on image processing technology was proposed.We use the chromatic aberration of mushroom and surrounding soil to transform the collected pictures into grayscale maps,and apply two value processing.The percentage of white pixels in statistical grayscale represents the growth coverage of the area.According to this,the structure and facilities of mushroom house were analyzed,and two problems were mainly studied:(1)Affected by the working principle of central air-conditioning,the temperature and ventilation degree in the mushroom house were difficult to be balanced,we need to analyze the data to achieve coordinated control.(2)Each vent has more than one control area,which affects multiple areas within a range.After the occurrence of environmental control actions,the influence of the other areas controlled by the vents needs to be predicted and evaluated.The clustering algorithm is used to establish a target monitoring system module,which can accurately detects the areas that most need to regulate environmental factors.It makes the producer accurately concentrate on finding the best regulatory areas of the growing environment in mushroom houses with a large number of mushrooms.The software development of automatic monitoring system for mushroom growing chamber is carried out.Under the Windows7 system platform and the Java language development environment,the software design that covers the above system functions is carried out with the C/S architecture.The design process mainly includes the software architecture design,the software function design and the database design.The UI design of the system includes four main modules: safety control module,monitoring module,control module and overall control system settings module.These allow monitoring for edible fungi growth and environmental factors more accurately,so as to increase crop yield,improve quality,and growth cycle,economic benefits adjustment.
