Multi-Parameter Online Monitoring Of Soil Composition And Design And Implementation Of Acquisition System

In order to meet the requirements of soil composition information monitoring,in this paper,a data monitoring and acquisition unit is designed using FPGA logic development technology and sensor technology,Web cloud platform development technology and database storage technology to design a data cloud display platform,and finally completes a soil composition monitoring service system that can monitor data in real time.On this basis,a soil comprehensive index quality evaluation model was established to evaluate and predict soil quality.The main research work is as follows:1)Monitoring terminal hardware circuit realization.In the hardware circuits,spartan6 series can meet the requirements with the FPGA of Xilinx Company as the core.The hardware circuit mainly includes FPAG minimum system circuit,sensor circuit,wireless communication module circuit,completed the design of the hardware circuit.2)Monitoring terminal software logic implementation.Verilog language is used to develop the logic of the hardware system,including the development of modules such as data packaging,instruction parsing,sensor control,data cache processing,etc.,which is connected with the wireless communication module to realize data acquisition and upload.3)Implementation of data cloud display platform.In the Intelli J IDEA development platform,Java,SQL,HTML,CSS and JavaScript are used for Internet Web development under the SSM framework,providing visual information.After the completion of monitoring software development,the software is tested,mainly to test whether the software can meet the established requirements.4)Soil comprehensive index quality evaluation model.After years of development,there are many kinds of soil quality evaluation models.On this basis,a comprehensive quality evaluation model which combines several evaluation models is proposed to evaluate soil quality.After the completion of the design of the whole system test,we can see that the system designed in this paper meets the reliability and real-time data upload,can be widely used in the field of monitoring.
