Design Of Portable Agricultural Machinery Remote Control Terminal System

With the rapid development of agricultural modernization technology,unmanned agricultural machinery has become a hot spot in the research of intelligent agricultural machinery.Agricultural machinery control terminal is one of the important components of unmanned agricultural machinery.Most of the existing agricultural machinery remote control systems are PC client terminals,which are mainly used indoors and are not easy to carry out to work.This paper combines remote control technology with Android technology to develop a portable agricultural remote control terminal system.The main research contents are as follows:Firstly,based on the analysis of domestic and foreign research status,the overall design scheme of portable agricultural machinery remote control terminal system is given.,completed the system frame design and hardware selection of the terminal system.Secondly,the key technologies of portable agricultural machinery remote control terminal system are studied.Including the communication protocol based on serial communication to realize terminal and unmanned agricultural machinery,realize agricultural vehicle state data acquisition and remote control of unmanned agricultural machinery;receive coordinate data based on user layer communication,complete coordinate data processing and display;and coordinate data Automatic path planning algorithm.Finally,completed the development and implementation of portable agricultural machinery remote control terminal system.It adopts multi-thread mode and uses Java language programming to realize the functions of system such as map browsing,device connection,work area display,work path planning,remote control,historical path playback and agricultural machine status information display.After the laboratory tests its function,the system is used normally,the communication is stable,the path planning efficiency is high,the positioning accuracy is high,and the human-computer interaction effect is good,which basically meets the system design requirements.
