Scheme Design And Verification Platform Development For The Control System Of Intelligent Agricultural Machinery

Intelligent agriculture refers to the technological upgrading of agricultural production methods.With the development of science and technology,many new technologies have been added to modern agriculture to solve problems in traditional agriculture.The intelligentization of agricultural machinery and equipment is not only a component of intelligent agriculture,but also a basic guarantee for the realization of intelligent agriculture.Intelligent agricultural machinery is a typical representative of the intelligentization of agricultural machinery equipment.Intelligent agricultural machinery is an advanced equipment that combines satellite positioning,image acquisition,computer aided and other technologies."Shen Nong I"is a processor chip independently developed by China that can serve intelligent agricultural machinery.Based on the "Shen Nong I"chip as the core,this paper establishes a pre-verification system for agricultural machinery terminals that can be applied to intelligent agricultural applications.The system completes the board-level integration of the "Shen Nong I" chip and a variety of information equipment,and can be used as a control center for intelligent agricultural machinery.In view of the requirements of intelligent machinery,such as automatic driving and intelligent networking,this paper divides the system function into four parts:positioning navigation,information collection,human interaction and data communication.Based on the practical application of agricultural machinery and the technical situation of the existing agricultural machinery control platform,this paper propose,s a design scheme of intelligent agricultural machinery control system.The solution uses GPS(Global Positioning System)and BDS(BeiDou Navigation Satellite System),using the inertial device to obtain the attitude information of the system,using machine vision equipment and various sensors to collect environmental data.Data transmission is completed by means of communication such as 4GA/WiFi/Bluetooth.During the research of the thesis,the communication-based displayless processor of the "Shenong I" chip is designed and implemented two graphic display schemes based on Ethernet and USB to provide function extension of the processor display function;in addition,the paper also proposes an innovative solution method,which can effectively improve the anti-interference of attitude solution.There are two main reasons for the thesis.One is to verify the effectiveness of the design through the development of the hardware platform.Second,the hardware system can provide a chip-level design verification platform in the "Shen Nong I" chip design.The test shows that the design proposed in this paper satisfies the functional requirements of the system;through the platform,some design problems of "Shenong I" chip are found,and feedback is given,which plays the role of chip verification.
