An IoT-based Hierarchical Control Method for Greenhouse Seedling Production

Abstract

The development of agriculture modernization leads to a flourish in high-tech equipment agricultural production, IoT-based greenhouse seedling production is the most presentative one. However, for the great majority of the seedling production factories, the data stream collected from IoT sensors only be applied for display, failing to assist the resource utilization and order target completion. To fill this gap, this paper provides an IoT-based system implementation architecture and a hierarchical control method for greenhouse seedling production, which make use of history monitoring data, real-time monitoring data, and seedling growth model, aiming at achieving the target growth along the predefined timeline as well as saving the additional energy cost. The proposed method is easy to implement in practical production and offers a valuable reference to other precise agricultural projects.
