[Abstract]:The Internet of things is a new technology that connects every object in a system and makes it a whole. The integration of the Internet of things technology into the greenhouse monitoring system can make the greenhouse monitoring system more intelligent and coordinated. In order to make the greenhouse monitoring system more information and interactive, the system designed the whole greenhouse monitoring system of the Internet of things from the aspects of hardware and software. The monitoring system is designed according to the hierarchical idea of the Internet of things. The underlying wireless sensor network collects data and transmits control signals. The collected data and control signals are converted into format in the gateway. In the Internet of things server stored and forwarded to the Internet for monitoring terminal equipment view and operation. The routing protocol and information fusion of the sensor layer of the monitoring system are studied emphatically. The communication efficiency and data security of data transmission are changed by designing the networking mode and the communication transmission process. The MATLAB simulation curve of the father tree routing protocol is designed to verify the equilibrium of the routing protocol. The weighted data fusion based on trust degree and packet compression technology are used in the data processing of sensor layer, which effectively solves the problems of poor load balance and excessive energy consumption. For the greenhouse control system in the processing layer of the Internet of things, the fuzzy PID control algorithm is used. The whole greenhouse monitoring system is simulated on the MATLAB as the controlled object, and several algorithms are compared, and the results are satisfactory. In the application layer, the database and WEB server are configured, and the B (browser) / S (server) mode is used in the monitoring interface for the development of mobile terminals such as mobile phones. In the aspect of system hardware, the model of core hardware, such as sensor, gateway and server, is selected, and the hardware performance is analyzed. Based on the above software and hardware, the whole design of IOT monitoring system has achieved the desired information interaction, and the performance of each aspect has been effectively improved.
