电喷发动机故障诊断专家系统的研究

Development of an expert system for fault diagnosis of electrical ejection engines

针对目前国内汽车电喷发动机维修过程中存在的问题 ,利用模糊综合评判的原理和方法对电喷发动机的故障进行分析和诊断 .并在 Windows环境下 ,将模糊诊断技术与计算机多媒体技术相结合 ,研制出电喷发动机故障诊断专家系统 ,经杭州市多家汽车维修企业使用 ,表明该系统具有推理过程简单。

Aiming at the problems existing in maintenance of electrical ejection engines, principle and method of vague comprehensive evaluation were applied to analyze and diagnose the faults that can be met with in such engines. A fault diagnosis expert system that based on the combination of vague diagnosis technology with computer multimedia technology was developed. Having stood up to tests in several automobile maintenance enterprises in Hangzhou city, the system showed its merits in inference: simplicity, high speed, accuracy, and so on.
