Design Of Integrated Network Architecture For Marine Electronic System

With the rapid development of information technology in twenty-fisrt century, emerge in an endless stream of advanced theory and equipment, navigation technology ushered in the great impact and challenges. In order to ensure the safety of navigation, more and more marine electronic equipment used, the complicated applications of marine electronic equipment also make the problems of information and control of ship outstanding. The integration system of marine electronic system, can effectively monitor the ship information, and make full use of the various kinds of the marine electronic equipment, ensure the safety of ship navigation. Integrated marine electronic system as a comprehensive treatment system of modern ship, its research is imminent.This paper in view of the above problems, analyse the advanced communication technology and combine the actual situation of ship, design the integrated system of marine electronic system, and then reaseach, design and verification the key module of the integration system, and finally test the integrated system of marine electronic system. The main reseach contents are as follows:1. Study on the design of integrated of marine electronic system. Fisrt, study the functional requirements of the integration system of marine electronic system and analyse several data bus technology in common use, and then combined the technical characteristics of the MIL-STD-1553 B protocol and fiber channel technology, design the scheme of integrated system of marine electronic system, and briefly introduces its the working mode.2. Research on the interface module between fibre channel and MIL-STD-1553 B bus of the integration network architecture of Marine electrical system, custom the special protocol of the integration network according to the properties of the two protocols, and then, on the basis of the core module, carried on the thorough research and design for the key module—protocol conversion module, and at last, design the key function module in the process of protocol conversion.3. Study the information acquisition and monitoring subsystem of the integration network architecture of marine electrical system. First of all, we have a generally introduction of the MIL-STD-1553 B bus technology, especially have a detailed introduction of the signal words. Then, divide the subsystem into three module, they are the system control module, information acquisition and control module and system monitor module, and at last, carry on a detail research and design of the information acquisition and control module and the system control module.4. Study on the FPGA design, realize and verification of the key modules of integrated system of marine electronic system. Firstly, select the FPGA chip according to the specific resource requirements of the hardware realize of integrated system of marine electronic system, and then introduced the overall logic design; Then according to the functions of the integrated system, testing the functions of the key modules and testing the system performance, by building a laboratory test environment.The paper analyse the key function of the integrated system of marine electronic system through the study of domestic and foreign advanced marine integrated system, using the MIL-STD-1553 B protocol and fiber channel technology to design the integrated system of marine electronic system, improve the real-time of the ship through the use of high bandwidth and high rate, and realize the integrated of marine command and control. The integration of marine electronic system design in this paper has greatly function improved compared with other marine integration, can provide a technical reference for our country navigation development.
