The Design Of Wireless Monitoring System For Mushroom Cultivation In Greenhouse

China's agriculture is in a critical period of transition from traditional agriculture to modern agriculture.Cultivation is changing from the small peasant cultivation to large-scale facility cultivation. With the development of communication technology and automation technology, the greenhouse environment monitoring and control system is going to realize the informatization and automation. Mushroom cultivation is an important part of agriculture in our country, the edible fungus production accounted for 70% of world output in China, the biggest in the world. Edible fungus production ranks sixth in the planting industry in our country, follows the grain, cotton, oil, fruit and vegetables, but the mushroom cultivation in our country is based on scattered production of manual operation of small scale.The plant management link needs a large number of human resources.The existing mushroom greenhouses are in low automatic degree. Monitoring management needs a large number of wiring, with complex installation.It is not convenient for management and production. With the development of technology in greenhouse wireless sensor network of mushroom cultivation,we can improve the mushroom cultivation greenhouse automation in our country,saving human resources, reducing the wiring, giving convenient management.For the shortage of communication and transport in greenhouse monitoring and control system for mushroom cultivation in our country.In this paper, we design a mushroom cultivation in greenhouse wireless monitoring system based on Zig Bee.According to the study of the mushroom growth environment,this system needs temperature and humidity, substrates,humidity, light, carbon dioxide concentration multiple nodes sensor to be inside the greenhouse for data collection. Zig Bee terminal equipment is made of the master control chip CC2430 and sensor.Batteries can work over months or even two years.Data can be send to Zig Bee coordinator in a certain communication format by Zig Bee wireless module.The Zig Bee coordinator work as the main nodes to construct star topology.The number of Zig Bee terminal equipment can come up to 65535. Coordinator of the single chip microcomputer work as a main control agency, according to the environment of system, setting threshold value to control the corresponding actuator. Various data acquisition nodes and the master is controlled by Zig Bee wireless module for data transmission.It has realized the automation,wireless. Zig Bee coordinator is the gateway system, connecting the Zig Bee network and Internet.It can not only display the data according to the results, but also send data to theInternet, realizing data view in a remote real-time way.
