摘要
当前对于设备的故障诊断专家系统,无论在设计上还是实现上,都受到很多客观因素的制约,使得专家系统的实用性和效率都受到了很大的影响。该文从实际应用的角度出发,在已有故障树诊断和规则推理诊断方法的基础上,提出了一种基于专家规则匹配的、可成长的故障诊断专家系统模型,并给出了基于该系统的推理算法和成长机制。该系统模型着重于提高诊断系统的效率和实用性,具有一定的通用性,并在实际项目中取得了较为成功的应用。
Currently, sorts of objective factors limit the design and application of fault diagnosis expert systems. From the perspective of practicability, a fault diagnosis expert system model was brought about with fault tree and rule matching based on former fault tree diagnosis and rule inference methods, and the deducing algorithm and growing up mechanism in the system were given. This system model mainly focused on the efficiency and facility of the fault diagnosis system, thus it could be applied generally to some extent. In specialty, it has had a successful application in project.
