军用导航设备故障智能诊断的DSS软构件技术

DSS-Based Software Component Technology for Intelligent Malfunction Diagnosis of Military Navigation Equipment

传统诊断仪器对导航设备进行故障检测诊断,只能局限于固定对象,软件可重用性和移植性差,故提出基于决策支持系统(DSS)的故障智能诊断软构件设计思想。该设计将DSS与软构件相结合,用专家系统的软构件技术开发导航设备故障智能诊断系统软件。采用DSS和人工智能技术、集成事实与规则2种知识表达方法,设计出一种结构化的故障智能诊断系统。它由专家系统、人机接口、主控计算机、知识获取机构、系统知识库、推理机和解释器、动态数据库、模糊故障诊断模块、神经网络知识库、问题处理和测试等组成。

The malfunction of navigation equipment monitor and diagnose is detected and diagnosed with traditional diagnostic instruments, which limits only on fixed objects because of its software lacks of ability of reuse and transplantation. So, put forward a software component plan for intelligent malfunction diagnosis based on DSS (decision supporting system). In this plan, combine DSS with software component, the software component technology of Expert System (ES) is applied to exploit the software of intelligent malfunction diagnosis system for navigation equipment. A structural intelligent malfunction diagnosis system is designed with DSS and artificial intelligence technology, the two expressional methods of knowledge such as facts and rules integrated. This system consists of ES, human-machine interface, main controlling computer, knowledge obtaining mechanism, system knowledge repository, dynamic database, fuzzy diagnosis module, NN repository and so on.
