The Research And Development Of Intelligent Greenhouse Controling And Detection System Based On Internet Of Things

The technology for the Internet of Things(IOT) is to connect everything to the Internet for information exchange and telecommunications through a variety ofinformation sensing devices according to the given protocols, so as to realize the intelligentizcd identification, location, tracking, monitoring and management. Based on the characteristics of Hebei Province region’s climate and greenhouse, the Internet of Things are used to agricultural greenhouse intelligent control in this paper, The complicated and changeable environment of a greenhouse is compared to the“article ”with an Internet connection,the perception layer of the system has three nodes which include acquisition nodes、the master node and execute driving node,the perception layer access the Internet through the mobile communication module,so the greenhouse site can be controlled by the master node and control software and the information of the greenhouse can be get by remote monitoring software of the application layer through the internet.Through the analysis of the facts of the current rural areas, this paper used mobile communication GPRS network to communicate. So in this paper the GPRS mobile communication module is used for transmission of information.The hardware of the entire system is designed. The system hardware design includes: acquisition node(CO2 concentration, temperature, humidity, light intensity acquisition), the master node, alarm messages and mobile communication module, the actuator driving nodes.The system uses a fuzzy neural network has high intelligence as a control algorithm, the system has good control effect in changing greenhouse replication system.The software of the entire system is designed,including: Acquisition Node(carbon dioxide concentration, temperature, humidity, light collection procedures), Zigbee communication program design, the master node design, design-driven execution nodeAt last,the remote monitoring software of the application layer is designed, the entire system is debuged and test,including: the communication between the master node and the acquisition node/the actuator driving node, the remote monitoring terminal acquire the data from the greenhouse, the actuator driving node drive the relay.
