Research On Agricultural Greenhouse Environmental Monitoring System Based On ? Technology

In recent years,along with the development of centralized agricultural facilities,gradually began to normalize,scale of the development trend,at the same time for the intelligent management of greenhouse also put forward higher requirements.The only way for the development of modern greenhouse is to use the greenhouse control system to complete the long-distance communication and further realize the integration of relevant production and management in the greenhouse.Mainly of greenhouse control system of the external environment factors for control and management,respectively is: temperature,light,rainfall,humidity,wind speed and wind direction related to climate factors,based on the related parameters of system setting,and use a series of control measures,reasonable and effective regulation of temperature,illumination and humidity in greenhouse environment factor,at the same time the development of suitable for the crop to grow the most suitable greenhouse ecological environment system.In this paper,the main characteristics of the greenhouse environment control and management,and the use of sensors and data acquisition card and other related hardware equipment and system,to achieve the greenhouse environment temperature,humidity,illumination,carbon dioxide concentration and other relevant environmental factors data acquisition operation.And in the aspect of software,the system mainly adopts Lab VIEW virtual instrument platform for running,not only can greatly improve detection control precision and the speed of data processing,but also effectively implemented within the greenhouse environment on the main factors related to data real-time acquisition and real-time display of information and the accurate signal data output and automatic processing work.Greatly reduce the interference of human factors,so as to further strengthen the effectiveness,stability and accuracy of the measurement and control system.
