Research and Implementation of a Modern Agricultural Greenhouse Cultivation System Based on Internet of Things

With development of internet and information technology, the traditional agricultural production cannot meet people's demand. The IoT (Internet of Things) technology is now taking this opportunity to modernize agriculture especially the greenhouse planting industry. This paper proposed a novel intelligent greenhouse cultivation system which not only liberate the farmers' labor force but also break constraints on disastrous weather shock, pest outbreak and other undesirable environment limitations. This system have been put into practice in southeastern China, including four functional parts, which are environmental parameters collection, data transmission, information processing, and data regulation and feedback control. These useful data acquired from IoT sensors were utilized to evaluate plant growth and predict the amount of liquid fertilizer to minimize waste of resources. Besides, a reliable PLC (Programmable Logic Controller) was adopted to enhance resistance to interference. Meanwhile, remote computers were adopted as a monitoring center to guarantee the flexibility of whole control system.
