Water and Fertilizer Integration Intelligent Control System of Tomato Based on Internet of Things

摘要

The main body of this article shows a system designed to improve the level of greenhouse irrigation and fertilization automation in China, while improving the utilization of water and fertilizer resources. Tomato greenhouse irrigation was used as an example to design an intelligent control system for tomato water and fertilizer integration in the greenhouse. The system is based on the optimal growth conditions of greenhouse tomatoes, combined with the impact of time on greenhouse tomatoes, using NB-IOT technology, information processing technology, information acquisition technology and other networking technology. The system has two sub-modules: tomato water and fertilizer integration intelligent control module and intelligent warning module. The system improves the precision of smart irrigation and fertilization in greenhouse tomatoes. In addition, in order to facilitate the user's real-time supervision of the greenhouse, the system is equipped with a dedicated mobile phone APP. Experiments have shown that the system greenhouse environment information collection and uploading are very stable, and tomato growth environment is controlled reliably. The system satisfies the needs of modem greenhouse planting management, and significantly improves the benefits of tomato production.
