Remote Monitoring System of Greenhouse Environment Based on LabVIEW

摘要

In order to solve the problem of low automaticity and poor real time in the current monitoring approaches for greenhouse, a remote environment information monitoring and distributing system for greenhouse based on ZigBee and WEB technology was developed. By applying LabVIEW virtual instrument platform, the field monitoring system can sample real-time environmental information in greenhouse with the wireless sensor networks and simultaneously transmit it to PC through RS-232 bus. The information distributing system establishes the connection between the field monitoring system and Internet and transmits the acquisitioned information to the WEB data server. The remote monitoring system is featured with satisfactory automation, intelligence and graphics. Experiment results show that the system has higher efficiency for the real-time monitoring result, and can significantly reduce the workload for greenhouse environment monitoring. The system can be used for evaluation of greenhouse environment and bring out the basis for modern greenhouse control.
