Applications And Design Of Multi-channel Data Acquisition And Processing Software For Protected Agricultural Area

In recent years,protected agriculture has become a mainstream development direction of future agricultural producing.It is an efficient modern horticulture method for increasing crops production that many universities and institutes have carried out demonstration and promotion of modern protected agricultural areas.Actually,the data collection is mainly based on manual acquisition in traditional agriculture.However,the work efficiency of manual acquisition,especially in multi-component and multi-location data,cannot satisfy the requirements of users,such as frequency,accuracy,storage,and processing of data collection.In order to meet the requirements and improve the work efficiency of data collection,a multi-channel data acquisition and processing software based on.NET platform is designed and implemented in this paper.The designed software can achieve the collection,manipulation,storage and display for the data that from large-scale,multi-type aware equipment in agricultural areas.Meanwhile,it is obvious that the advantages of designed software in simplifying the operation,strengthening the versatility,enhancing practical functions,and improving the production efficiency and management level of the protected agricultural area.The main research work and contributions of the dissertation can be summarized as following:(1)Analyzing the development status of domestic and foreign protected agricultural data acquisition systems,the overall architecture of a multi-channel data acquisition system for protected agricultural areas is proposed by referring to many practical engineering project cases.Furthermore,through the sensor selection,multi-channel data acquirer function design and software functions requirement analysis,the functions of automatic acquisition and data management for relevant agricultural parameter data are implemented.(2)Considering the requirements of software function,the overall architecture of proposed system is constructed based on the three-tier structure model of data layer,business layer and presentation layer.Moreover,the core functions and key mechanisms of designed software in data acquisition,interface switching and data allocation are designed in detail by using UML timing diagrams and flowcharts.(3)Leveraging the.NET Framework 4.5 framework of VS2010,C# language is mainly employed to design the program code to implement the functions of multi-channel data acquisition and processing software acquisition,processing,storage and statistics.In addition,according to the results of unit test,function test and demonstration application of the designed software,the designed software can operate stably in the system and satisfy the requirements of the data acquisition function,accuracy and real-time of the protected agricultural area.
