Design Of Remote Monitoring System For Intelligent Greenhouse

The application of greenhouse system can improve crop yield,reduce labor cost,and bring good economic,social and ecological benefits.In recent years,with the deepening of the research and application of greenhouse monitoring,the technical level of greenhouse monitoring in China has been greatly improved,but there are still deficiencies in the management and control of greenhouse monitoring equipment,and there is still a great room for improvement in the development of greenhouse monitoring.To meet the needs of the development of greenhouse monitoring system,this paper designs an intelligent greenhouse remote monitoring system.The system uses ZigBee technology to build wireless sensor network,and uses ZigBee technology with low cost and low energy consumption to realize the network connection of greenhouse monitoring system.The system uses CC2530 as the main controller to realize data collection and processing.The greenhouse environment parameters are sent to the server through GPRS module packet data network.The server carries out intelligent analysis and control of the data.According to the greenhouse environment value set by the user,the comparative decision is made,and the control command is sent to the actuator to control the greenhouse environment.At present,the PID control strategy commonly used in industrial control can't adapt to the dynamic change of greenhouse environment,and the fuzzy PID relies too much on expert experience.In this paper,the improved particle swarm optimization algorithm is used to optimize the fuzzy PID controller.The particle swarm optimization algorithm is used to optimize the fuzzy controller dynamically,which has the characteristics of fast optimization speed and less optimization parameters,so as to improve the precision of greenhouse control.Through the simulation and contrast experiment of the environmental temperature in the greenhouse monitoring,the validity of the fuzzy PID algorithm of particle swarm optimization is verified,and the good effect is obtained in the greenhouse monitoring and control.This paper also designs a web program based on B / S architecture.Users can understand the environmental conditions in the greenhouse without leaving home.Through the web program control server software,the remote control of the greenhouse environment can be realized,and the greenhouse environment can be adjusted to meet the needs.The test results show that the system functions and related indexes meet the design requirements.The intelligent greenhouse remote monitoring system designed in this paper has reasonable structure design,fast data acquisition speed,high control accuracy,simple interface design,stable system operation,and can effectively monitor and control the greenhouse environment,which has better use value and significance.
