Research And Implementation Of Environmental Monitoring System Of Greenhouse Based On WSN

Along with the strategic transformation of agricultural development in our country and the increasing demand for fresh agricultural products from people,it is incapable of keeping pace with agricultural development to continue open-air cultivation as well as traditional greenhouse production management.This paper,applying WSN monitoring technology to greenhouse management,also combining with the up-to-date greenhouse production management,help users to achieve efficient production management.It is of great significance to give impetus to the development of greenhouse production management.This paper,aiming at integral construction of environment monitoring system in the greenhouses,makes an in-depth research of the application of WSN in the field of greenhouse production management,the mechanism of how WSN has access to IPv6 network and the design and implementation of this system.In order to help modern peasants manage the large-scale greenhouses effectively,this paper carries out an analysis of shortcomings of traditional greenhouse production management pattern,and introduces WSN to the design improvements of greenhouses production management,forming the production management thoughts which contains two management models.At the meanwhile,according to the demands of new-type management model,the overall design of monitoring system was carried out in this paper.In this paper,in order to make WSN have access to IPv6 network,an access mechanism of WSN was designed.And by the means of transplanting Contiki to the platform of MX231 CC and AVR-USBSTICK,many things,such as WSN access,gateway data forwarding,multi-hop data transmission,node environment data collection and sending and receiving,were realized.This paper,combining with the overall system design,also based on HTTP,achieves a local middleware which is an integration of functions such as data request,XML data analysis and node information management,by means of script pre-warning.Furthermore,this paper,based on the technology of AJAX,achieves a remote monitoring system which can provide a visualization of real-time environment data distribution of different places in the greenhouses,a visualization of local environment data fluctuations,a visualization of real-time environment data comparison between greenhouses,historical environment data query as well as early warning information allocation.Finally,as the results of system operation indicate,the system can collect environment information in real time and provide visualizations of the environment data from different perspectives of part,whole and clusters of greenhouses.What’s more,the early environment warning mechanism can effectively solve the problem of long-term needs of manual labour to be on duty,promoting unmanned production of greenhouse production management.Above all,the research results in this paper have a certain practical value,even to some extent,providing a reference for the applications in related fields.
