| Abstract: | Reasoning mechanism which affects application and correctness oi expert system is an important element of expert system. The paper introduces, reasoning mechanism of expert system in hydraulic system of farming machine. The paper studies, not precisely reasoning method based on fault tree theory in reasoning mechanism. According to the testifying of exploration of the expert system, the reasoning method has high diagnosing efficiency and correctness when it is applied in fault diagnosing expert system. |
