A Study On The Realization For The Applied Technology Of Integrated Navigation Information Processing Based On Linux

Integrated navigation technology started from space navigation, developed from the 1970s on the voyage navigation area. The research of integrated navigation in our motherland began from the end of 1970s, now it has already grown to a integrated navigation system with electronic chart and integrated navigation console. In recent years, along with the progressing of computer and the diversification of the navigation equipment.The integrated navigation system progress more and more information, its function is tending toward perfection, and the automaticity is also getting higher and higher. Thus, the command to progressing of navigation information is coming. Now, integrated navigation technology has become the most popular technology of modern ship navigation. So the study of design and implementation of information progressing which satisfied to the ship navigation has become more significant.This subject take integrated navigation information progressing system as backgourd, mastered the research state and the orientation of development, unfolded study of the integrated navigation design and implementation.Firstly, this article introduced the linux operating system and its features, choose linux as a operating platform of information processing to design the application software, study the cut ane setup of Linux nucleus.It choose Qt as the developing tool of application software based on Linux, do a deailed analysis to the signal and slot mechanism of Qt, so do the procedure of Qt programming.Secondly, the article combined the function comman analysis of integrated navigation information progressing to design the application software, which was devided into three parts:information progressing part, interface part and man-computer interaction part.and do a detailed design of each part.Finally, according the device file technology, this paper accomplish the driver of serial prot based on Linux; also the network communication of integrated navigation information progressing system by the network function provided by Qt; it also developed a friendly, beautiful and effective man-computer interface by Qt designer.Thus the subject achieved aim of design demand, improved the application software of integrated navigation information progressing system.
