A Design Of Integrated Ship Information System Based On Embed System

Marine Integrated Information System, is an integrated a variety of ship equipment, intelligent information systems, it uses ship's various devices information through computer systems, fast and accurate processing to improve the security features and automation ,intelligence.The issue referred to in the main vessel combines integrated information system plays a key role for the safe navigation of the ship positioning and navigation systems and automatic identification system (AIS) and meteorological navigation warning system (NAVTEX) the contents of the two parts of the system design.AIS ship terminal by the base station and the common form, is a set of network technology, modern communication technology, computer technology, integrated digital navigation systems and equipment. NAVTEX is the Global Maritime Distress and Safety System (GMDSS) is an integral part, is also part of the global navigation warning system is provided for GMDSS radio ship ground only means to receive safety information, including receiving frequency 518kHz, 486kHz and 4209.5kHz, broadcast To provide an important guarantee for safe navigation.This topic used powerful method to realize ISIS . The above two kinds of device information, the subject of mining Xscale family of embedded processor PXA255, according to system requirements, set up the frequency to 400MHz embedded platform, and on this basis, tailoring the Linux kernel transplantation. Respect for the human-computer interaction was developed by the Nokia C + + cross-platform GUI application framework QT, it is completely object-oriented, easily extensible, allowing component programming. In this system, key information on the appropriate algorithm processing, intuitive, simple graphical interface to achieve a ship-borne equipment, information disposal.Where the subject of the project through co-ordination of planning and implementation, with a clear definition of such applications workable solution. Starting from the product requirements, system architecture review, implementation of the program on the system, the function of each module and character from the product of research and development aspects of the implementation: the selection of hardware platform design, hardware implementation of the system validation, software system selection core algorithm, the software implementation of the system validation.
