| Abstract: |
| According to technical requirements of intelligence and automation for fault diagnosis of remote sensing satellite receiving system,fault characteristics of system is analyzed and the architecture of fault diagnosis expert system is presented. Through analysis of the system equipment monitoring information and task flow,the establishment and analysis of the fault tree,using production rule for knowledge representation,the knowledge base of fault diagnosis expert system is established and fault location is realized by heuristic model of forward reasoning. The fault diagnosis expert system is used in actual engineering projects and has improved the fault diagnosis efficiency of remote sensing satellite receiving system. |
