Design And Implementation Of The Key Technology In Greenstuff Monitoring System Based On Qt

With the continuous progress of science and technology in the world,people's demands for the quality of work and life are greatly improved.People are eager to use more modern tools and means to replace the cumbersome and pure manual work of the past.From the industrial production of automated assembly line,to the restaurant in the robot,the Internet of things intelligent machinery and equipment not only improve the efficiency of production,reduce the labor cost,but also improve the quality of products.And the environment,meteorology and soil factors in the greenhouse,the growth and development of crops,the implementation of cultivation techniques,pest prevention and so on are very important.At present,the development of crop parameters automatic detection system is in the initial stage,and the agricultural environment detection is based on the fixed-point collection of weather station,which can not collect the ecological environment parameters of the wide area farmland and orchard.Therefore,it is needed to study,design and develop a new system which is suitable for the detection of environmental factors in farmland or orchard.In recent years,with the development of Internet of things technology has been widely concerned by the industry's sensor technology,has been the initial application in the target monitoring and tracking.This thesis from the basic concept of network application system,elaborated on the IOT application on crops in vegetable greenhouse in.First of all,through the single-chip microcomputer to collect the environmental data of crops,so as to form the real data and the basic data as a trend chart of environmental data.Secondly,the collected data is stored in the relational database through Qt technology,which plays a role of the bridge from the data acquisition of hardware equipment to the software application data display.Finally,the data presented in the Web application,the system can achieve real-time monitoring of crop user environment change,can display the temperature and humidity of the crop at any time,and can display view the history of temperature and humidity,the formation of curve,to achieve early warning function.The system can be realized in the end of this paper,mainly used in the wide area of vegetable greenhouse temperature and humidity data acquisition.Concise interface design,user-friendly design of menu,make full use of information and communication technology will have a variety of sensor equipment items commonly linked to form a comprehensive,three-dimensional,high coverage of the Internet of things.Intelligent and efficient integration of information resources,optimize the allocation of resources,to achieve a harmonious and sustainable development of the physical environment and human society.
