Agricultural Information Remote Monitoring System Based On Internet Of Things

To It is a difficult problem to improve crop yield and ensure the growth of crops under suitable conditions.With the rapid development of Internet,network communication technology,through networking technology,Zigbee wireless communication technology,GPRS wireless network communication technology,sensor technology,data processing technology,automation,intelligent control technology,realize the interaction with the agricultural information data offer tribute to achieve crop information remote monitoring becomes possible,improves the temperature and humidity agricultural environmental light intensity,carbon dioxide concentration measurement accuracy,and characteristic parameters about the measured environmental information extraction after treatment.This paper first introduces the performance requirements of the system,and then puts forward the overall design of the system,through the system's perception layer,network layer,application layer,the system hardware architecture.The overall framework of the system by the environmental parameter acquisition module,data transmission module,control module,video module,alarm module,according to the change of the external environment,the modules of system function respectively,and by the fuzzy PID algorithm for temperature control of linear composite.Secondly,according to the functions of the system with the software model,software platform design of the system,through the real-time monitoring of environmental data information platform,and can effectively control the data and equipment,make the growth of crops in the best environment.Finally,combined with the hardware and software development,the overall design of the system is completed.In this paper,the stability and reliability of the system are tested in the laboratory and greenhouse.Under the condition of laboratory,the temperature and humidity data were collected accurately,and the stability of the system was verified.Under the greenhouse condition,the fuzzy PID algorithm is used in the decision-making process,which makes the data acquisition accuracy of the system greatly improved,and the accuracy of the scheme is further improved.
