The Research And Application Of Wisdom Agriculture Based On OPC UA Technology

The continuous progress of the times,the continuous development of science and technology,the emergence of information technology in the agricultural sector so that the production process has become automated.Wisdom agriculture that agricultural environment intelligent monitoring,gradually come into our views.In view of the fact that China's existing greenhouse monitoring system is mostly based on hardware,there are interface aspects of intuitive and flexible and low level of automation and other issues,intelligent agriculture solutions combined with advanced Internet of Things and software technology.In the industrial control,data collection and control gradually introduced a virtual technology to solve the monitoring system of some interactive issues.The use of virtual instrument technology development of the monitoring system,the data processing and display surface more intuitive,more flexible,wait for all the engineers affirmed.The OPC UA technology used in the system,is OPC upgrade version and being used more in the field of industrial.T The use of the technology,so that different hardware and software business in the development of products do not have to consider the interface problem.There's no need for each device to develope drive,greatly saving the cost.Labview has the characteristics of short development period,easy to learn and use,friendly interface,and is adopted by most engineers in data acquisition and control.In labview using OPC UA technology to make the communication between the host computer and the lower computer more convenient,to achieve the real-time data in the field device display in the host computer interface.The system mainly includes the user login,login user management,the impact factor in the greenhouse environment for real-time monitoring and curve display.Setting the scope of the environmental factor data range,the scope of the data to achieve the alarm,the alarm data stored in the database for later investigation.Ceating tables in MySQL to stroe the collected data in real time.The historical data query module can query data according to different time ranges and can query data within one day and one week.The lower position of the valve switch can be achieved both manual and automatic control mode control operation.The modules work well with each other,has completed the initial test system.Design requirements before the basic requirements have been achieved,the greenhouse can be fully monitored.
