推理机是专家系统的重要组成部分,直接影响专家系统的实用性和判断的正确性。文章探讨了农机液压系统故障诊断专家系统的推理机实现问题,研究了基于故障树理论的不精确推理方法,经过系统开发验证,该推理方法应用于故障诊断专家系统中,具有较高的诊断效率和准确性。
Inference engine is an important part of expert system, which directly affects the practicability of expert system and the correctness of judgment. In this paper, the realization of the inference engine of fault diagnosis expert system for agricultural hydraulic system is discussed. Inaccurate reasoning method based on fault tree theory is studied. After the system is developed, the inference method is applied to the fault diagnosis expert system and has high diagnostic efficiency And accuracy.
