RESEARCH ON ENVIRONMENTAL FACTOR MONITORING TECHNOLOGY OF AGRICULTURAL FACILITIES BASED ON INTERNET OF THINGS AND BIG DATA DRIVEN

摘要

The agricultural facility environm ent affects agricultural production, w hich requires accurate m onitoring and control. B ased on the Internet o f T hings technology, this paper designs an environm ental m onitoring system for agricultural facilities, w hich consists o f three parts: inform ation sensing layer, inform ation transm ission layer and application m anagem ent layer. The inform ation-sensing layer m onitors the environm ental data and transm its it to the application m anagem ent layer through the w ireless com m unication netw ork o f the inform ation transm ission layer. T he application m anagem ent layer receives the data and analyzes and stores it, and then form s a control instruction according to the re sult o f the analysis, and drives the operation-executing device to perform corresponding control operations. The system is used to m onitor and control the tem perature, light intensity, soil w ater content, and pests in the four vegetable grow ing environm ents in the greenhouse. The new m ethod can accurately m onitor and control according to the set values. The environm ental factors are m aintained in the m ost vegetables. W ithin the appropriate grow th conditions by big data, the Internet o f T hings-based environm ental m onitoring system can be applied in facility agriculture to achieve real-tim e m onitoring and precise control o f the environm ent.
