Computer Monitoring And Control System Of Greenhouse Based On Internet Of Things

Internet Of Things is a system in which each object is linked,so that it becomes a new technology as a whole.IOT technology into the greenhouse monitoring system,can make the greenhouse monitoring system more intelligent and coordinated.In order to make the greenhouse monitoring system achieve interaction,the system from aspects of software and hardware to design comprehensive monitoring system of IOT.According to the design of hierarchical thinking networking monitoring system into the bottom of the wireless sensor network to collect data and control signal transmission,data collection and control signal format conversion in gateway,network server is stored and forwarded to the Internet,for monitoring terminal equipment and operation view.In sensor monitoring system,communication efficiency and data security data transmission can be changed by the design of networking and transmission process,so according to the actual situation of the design of routing protocol based on parent tree,the simulation curves show the superiority of routing protocol.In the data processing of the sensor layer,the method of weighted data fusion based on trust and packet compression technology is used to solve the problem of load balancing which is not ideal and the energy consumption is too large.For the networking layer of greenhouse control system,using the fuzzy PID control algorithm,the whole greenhouse monitoring system as the object in the MATLAB,and compared with several algorithms,the result is satisfactory.The system configure the database and WEB server,monitoring interface using the browser / server mode,so that the development of mobile terminals,such as mobile phones.In the system hardware,the selection of the sensor,gateway and server and other core hardware models,and in the performance of the hardware are analyzed.The overall design of the monitoring and control system of Internet Of Things based on the above software and hardware has achieved the expected information interaction,and the performance of the system has been improved.
