Research Of Intellectual Breakdown Diagnosis For Telemetry Receiving Channel System

This thesis which elaborates on theory and tech-points of telemetry system and on its telemetry channel receiving system , introduces briefly current study progress on intellectual breakdown diagnosis and asorts the expert system acordding to the applying domain and fuction has the importance of guiding on the specifically tech and system's combination. Telemetry channel receiving and breakdown diagnosis system can be defined primarily as a diagnostic system. This artical discribes the intellectual breakdown diagnosis model and primarily designed a framework for the expert system. Telemetry channel receiving system make up of 6 parts which are the knowledge base , the reasoning organ, the integrated data base , the man- machine interface and the program of interpreting and information getting.After studying and comparing the good and bad of the certain expression for the technique, that is producing pattern, frame pattern and semantic network pattern which are in common use, build up a expressing pattern for specifically knowledge between the 3 pattern.-- the node pattern. which is a specifically knowledge expressing pattern brought forward by the understanding and recollection of the telemetry channel receiving system and the maintenance personnel. And it's a data framework expressing the case-hardened knowledge. By using repository of formula and chain list to make the complicated expert knowledge data base be storied and distributed which has excellencyies of OOA, efficiency, credibility and easy programming and maintenance. according to the characteristic of telemetry channel receiving system and the breakdown diagnosis system, bring forward the logistic diagnosis, width-first searching and rule based conflict deal method which based on the accurate reasoning.Put forward the intellectual breakdown diagnosis for telemetry receiving channel system , and described the mathematical matrix of the intellectual breakdown diagnosis on dianoetic level and preparatory ,contrived the framework of diagnosis expert system. The information repository with this structure has the excellence of object facing, efficiecy, reliability and is prone to programme and maintenance. On the expert system reasioning, and combinatting the conflict-clearing up tactic of rules and cases, find the satisfying searching result step by step.After analyzing in detail of the rule notation, network notation for semantic and framework notation In the process of designing ,I use UML(Unified Modeling Language) and VISUAL C++ 6.0 language and SQL SERVER 2000 which is good at data base management to carry out the telemetry channel breakdown diagnosis expert system and finely designed the illustrations of the system in expert system use case , knowledge base management and activities, breakdown reasoning activities, class pictures , searching method arithmetic and data structures. By doing these job, to make the software module be clear and easy to be expanded. The data base has also the excellency of easily operating , mighty fuction , exchanging information with outer data successfully , wrong tolerating and also be friendly and mighty to use. Being strictly tested, the expert system can finely fulfil the tusk of breakdown diagnosis and has a broad applicative value and further development.
