Design Of The Acquisition And Control Service Software For The Intelligent Agricultural System

Intelligent agricultural system can perceive the agricultural environment data,acquire and transmit the data effectively as well as control equipments remotely by using the internet of things,cloud computing and other modern information technology,which promotes the process of the agricultural modernization efficiently.Acquisition and control service software,the most important part of the intelligent agricultural system server,is responsible for the network connecting,the information process service for data collecting and device controlling.Considering the big amount of the data links and the frequent client requests,acquisition and control service software is studied in the thesis,aiming at solving the low collected data's accuracy,the insufficient auto-management and equipment control ability of the intelligent agricultural system.The main contents are as follows:1.A simple decision algorithm,support degree measurement algorithm(SDMA)is proposed to solve the insufficient automation of the existing intelligent agricultural system.To improve the automation level of the system,support degree measurement algorithm is raised to realize the automatic selection of the most appropriate control strategy through matching the environment data for the time with the historical data in the database.The algorithm is simple to realize and feasible according to the experiments results.2.To improve the collected data's accuracy of the intelligent agricultural system and solve the problem of the missing information processing architecture,a n information processing model is designed combined with the blending matrix method,the adaptive weighted average method and SDMA,called three-layer information processing model(TIPM).TIPM has the ability of pre-processing the failure data,fusing the local data and auto-controlling the equipment.The TIPM used in the intelligent agricultural system is proved to be effective.3.Based on the feature of the intelligent agricultural system server,that it needs to handle the requests of several clients at the same time.The acquisition and control software based on IOCP is designed and realized with VC++,which integrates TIPM.4.Some related experiments are conducted,containing the communication function,the IOCP communication performance and the TIPM's algorithms of the acquisition and control software.Tests show that the software has the ability of supporting mass links of clients and satisfies the application requirements of the server.The software's communication success rate is high and the scalability is good.The anticipated design target is achieved.
