Design Of An Edible Mushroom Greenhouse Management System Based On ZigBee Technology

With the rapid development of China's social and economic level,people's food and clothing has been solved.Health concept also gradually enjoys popular support,the concept of modern health advocacy,a meat and a bacteria,which seems to indicate the importance of fungi nutrition to us.Edible mushrooms have some good function for us,1,inhibition of tumor activity 2,increase immunity 3,blood fat,blood sugar and so on.So more and more people love and attention edible mushrooms.China's large demand for edible fungi,but China's mushroom farming generally have low fruiting rate,yield and other phenomena,so edible mushroom farming urgent need for scientific monitoring and management.There are many kinds of edible fungi,each edible fungus needs difference growth environment,the same edible fungus in different growth periods also have needs different environmental.This requires us in the growth of different fungi environment to take the appropriate control settings,the mushroom room environment is most suitable for the growth of fungi,so that the production of edible fungi to maximize.The main factors that affect the growth of edible fungi are temperature,humidity,CO2 concentration,light and so on.The main effects are temperature and humidity.The change of temperature will lead to the change of humidity.The humidity also will lead to the change of temperature.They has a coupling relationship,and it is difficult to establish a precise mathematical model.Therefore,the control method of temperature and humidity fuzzy decoupling is introduced in this system.The design of fuzzy decoupling controller solves the problem of coupling between temperature and humidity,and makes the control of temperature and humidity more accurate.In this paper,the monitoring system based on ZigBee wireless network,and the growth environment of edible mushroom greenhouse is monitored by wireless technology.The terminal node is responsible for collecting the environmental parameters and passing it through the ZigBee network to the coordinator.The coordinator communicates passing the data through the serial port to the host computer.The host computer control system analyzes the collected information and the state of the control equipment and the turn-on time.Greenhouse use of plastic material is a plastic film,if not pay attention to easily lead to fire,causing serious losses.Based on this system joined the MQ-2 gas sensor,can be flammable gases,smoke and other gaswarning,the system can protect the greenhouse's security.The system uses CC2530 chip,with low power consumption,operability and other advantages.The traditional wired transmission data cabling trouble,it is not convenient to operate.Through the construction of ZigBee wireless communication network transmission can solve the above problems,not only can quickly and accurately transmit data,we can also establish a node network,in order to achieve the entire mushroom room monitoring and control.
