【摘要】 组合导航已成为导航定位系统发展的主流方向，我国组合导航系统的研究起步于70年代末，经过十多年的努力，发展势头迅猛，已广泛用于舰艇、测量船及其它船舶。组合导航系统肩负着舰船导航定位、姿态控制的重要职责，它的可靠性严重关系到舰船航行的安全性和定位的准确性，因而它的可靠性受到越来越多的关注与研究。故障检测与诊断技术和容错控制技术作为提高系统的安全性、可靠性的重要手段，日益引起人们的重视，成为控制理论继分析与综合技术之后的又一主要内容。而故障检测与诊断技术又是容错控制的基础，所以对组合导航计算机系统的故障诊断技术的研究具有深远意义。 本论文以组合导航计算机系统为背景，系统研究了故障检测与诊断技术及其在综合导航显控台上的应用。论文先简要介绍了故障检测与诊断技术的历史和发展现状，然后系统地介绍组合导航系统的原理，并对其可靠性进行讨论。根据组合导航计算机系统经常出现的故障提出检测与诊断的设计方法。 本文主要对组合导航计算机系统中的各种故障进行分析，对系统硬件进行离线或在线故障检测，为系统排除故障的决策提供依据。在此基础上对系统的内存、串口和网络的故障提出检测与诊断的方案，以提高组合导航计算机系统的可靠性。更多还原

【Abstract】 Integrated navigation has become the fashion of ship navigating and orientating systems. The research of Integrated Navigation System (INS) in our country start in the 70’s of 20th centuries. After the effort of more than ten years, it has got great progress. All kinds of INS have been applied in naval vessel, surveying vessel and other ships extensively. Because INS is responsible for ship navigating, orientating and posture controlling. It’s reliability concern the security and orientate accuracy of the ship seriously. Therefore, the reliability of INS attracts increasing attention and study. The technique of Fault Detection and Diagnosis (FDD) and Fault Tolerant Controlling (FTC) as important means of raising systematic security and reliability are getting people’s attention and become another main content of control theory after system analysis and synthesis. For FDD being the foundation of FTC, the research of FDD on the computer system of INS is significant.Base on the computer system of INS, the thesis systematically research the technique of FDD and application on Integrated Navigation Display & Control Console (INDCC). Its history of FDD and its recent development is introduced briefly. The principle of INS is described systematically, discuss about its reliability. Detecting and diagnosing method is put forward according to the faults of INDCC appearing often.This thesis analyses various kinds of faults in the computer system of INDCC, detects the faults of system hardware off-line or online, and provides decision-making basis for faults solution, and then the detecting and diagnosing solution for the faults of RAM, serial port and network, the reliability of thecomputer system of INDCC is raised.更多还原
