Design And Implementation Of Man-Machine Interaction System Based On Electronic Chart

With the rapid development of unmanned craft technology,the man-machine interaction system of unmanned craft is indispensable.In this paper,the design and development of man-machine interaction system of unmanned craft based on electronic chart are carried out.Through the introduction of electronic chart,the problem of information loss in the ocean area of ordinary map is solved,so that the unmanned ship can obtain the static known maritime risk,so as to improve the safety of the unmanned ship.The content is mainly divided into the following aspects:?.This paper presents a design scheme for man-machine interaction system of unmanned craft.Firstly,by analyzing the function and performance requirements of the system,the overall architecture of the system is designed.Secondly,the man-machine interaction system is divided into several functional modules.Finally,relevant design is completed for each module.?.The reading of chart data is realized based on s-57 chart data standard.Firstly,on the basis of reading s-57 chart data by GDAL/OGR,object object object matching is carried out.Secondly,the matching symbol description instruction is obtained from the lookup table and analyzed.Finally,in the process of drawing chart symbols,Mercator projection coordinate conversion and screen coordinate conversion are used to complete the coordinate conversion in the drawing of chart symbols.?.Based on VS2017 platform,the man-machine interaction system of unmanned vehicle was developed by using C# and WPF framework.First,add custom controls,buttons and display blocks on the system interface to complete the development of the system interface.Secondly,at the background logic layer,routing events are added to the interface controls to complete the issuing of control commands and the analysis of feedback information.Finally,through the TCP/IP communication protocol,the communication connection is completed.The feasibility of man-machine interaction system is verified by field test of unmanned craft.
