The Design Of Basic Display Platform For Vxworks-based ECDIS

With the development of the international standards of the ECDIS and the background that the ECS produced by our school is not compliant with the international standards, this thesis studies on the design and realization of the basic display platform for Electronic Chart Display and Information System based on Vxworks OS.Electronic Chart Display and Information System (ECDIS) which has lots of advantages such as incorporate functions, automatization, the standardization of the software and hardware and so on, is the only IMO sanctified substitute for the paper chart. And IHO, IMO and IEC have participated in the constitution of ECDIS standards together.At the beginning of this thesis, it does some research on the international standards, the Vxworks OS, the Vxworks's developed environment Tornado, Zinc and UGL which are the tools for graphic development and the coordinate transition.Then, by studying with the IHO TRANSFER STANDARD for DIGITAL HYDROGRAPHIC DATA (Standard S-57) and SPECIFICATIONS FOR CHART CONTENT AND DISPLAY ASPECTS OF ECDIS (Standard S-52), the paper gives the design and implement of the two important parts of the basic display platform. It discusses the content and the programme flow of the SENC which is transformed from Electronic Navigation Chart and used for improving the speed of displaying Electronic Navigation Chart. It also solves the measure and the programme flow of S-52 Presentation Library. This section is the most important and primary work of the paper.Thirdly, this thesis makes a brief design of the hardware and software of the ECDIS, especially the function design of the software.
