Design and Research of Intelligent Greenhouse Monitoring System Based on Internet of Things

Since the greenhouse has characters of temperature- humidity uneven distribution, strong coupling and traditional control strategy can't achieve the ideal control effect, the greenhouse monitoring system based on internet of things (IOT) is designed. The system uses a fuzzy neural network which has good control effectiveness in complex and changeable greenhouse system. Perception layer using ZigBee protocol for wireless communications, and greenhouse environment can be controlled by site control software/master node, which makes the system more effective and stronger. The master node uses mobile communication network to send sensing layer data to application layer and can send alarm SMS. This system has the characteristics of low cost, simple structure, flexible networking and easy extending, which adapts to the requirements of complex greenhouse control.

INTRODUCTION * The application and development in the field of internet of things in agriculture are particularly quickly in today's society. The intelligent agriculture based on internet of things will be more and more. Wireless sensor network (WSN), which is the core of the IOT technology, has the advantages of ad-hoc network, simple deployment, low energy consumption and easy manage(1-3). Wireless sensor network is a typical multiple hops network of ad-hoc network, and its self- organizing function can guarantee the network connected in the case of damage of part of the nodes. In the greenhouse environment, because of the uneven distribution of temperature and humidity, it requires a large number of sensors to monitor environmental information, and the big inertia of greenhouse environment leads to the slow change of quantity of state information(4-6).These features make wireless sensor network widely used in the field of greenhouse control. In the 21st century, with the continuous development of radio technology, and the coverage of each mobile operator
