Adaptive optical electronic control system self-inspection and fault diagnosis expert system

Abstract

The invention discloses an adaptive optical electronic control system self-inspection and fault diagnosis expert system. Based on fault tree analysis of the adaptive optical system electronic control system, the self-inspection and fault diagnosis expert system of the system is established and mainly comprises a human-machine interface module, a database module, a reasoning module and an explaining mechanism module. A system fault tree is designed and generated on the basis of fault analysis of the adaptive optical system electronic control system, a knowledge base of the fault diagnosis expert system is generated via fault tree knowledge, fault diagnosis reasoning is performed according to the knowledge base generated by the fault tree, and finally a function of the AO system electrical fault diagnosis expert system is realized. The diagnosis expert system is applicable to daily maintenance and fault diagnosis of the adaptive optical system electronic control system.

Description

technical field [0001] The invention relates to the field of adaptive optics systems, in particular to the content of self-check and fault diagnosis of an electric control system in the field of adaptive optics systems. Background technique [0002] The adaptive optics system is a large and complex system. The whole system involves different fields such as optics, mechanics, electronics, and control. Among them, the electronic technology covers the acquisition-processing-correction-observation and other stages of the adaptive optics system. With the development and maturity of adaptive optics technology, adaptive optics systems are more and more used in different fields such as aerospace, medicine, astronomy, and industry. The high complexity and wide application of adaptive optics system also put forward higher requirements on the reliability of its electrical system. At the same time, for the electronic control system of the adaptive optics system, the system modules are ...

AI Technical Summary

Problems solved by technology

At the same time, for the electronic control system of the adaptive optics system, the system modules are numerous and scattered, the application environment is complex and changeable, and the internal conditions of the system are also quite complicated.

Therefore, the inspection of the operating status of the electronic control system not only wastes a lot of manpower and material resources, but also is difficult to implement from the perspective of the system.

Moreover, the development of domestic adaptive optics system started relatively late, and the development of the discipline system is not very sound, and there are few domestic researches on self-inspection and fault diagnosis of electrical systems.
