摘　　要：为解决新型工程机械故障的现场快速故障分析与诊断难题,研制了工程机械故障专家诊断系统。其功能包括两个方面,一是维修决策与维修指导功能,二是维修教学与训练功能。系统硬件为通用计算机,软件包括专家故障诊断模块、维修方案确定模块、训教模块、帮助模块和打印输出模块等。系统的开发提高了工程机械的维修保障能力。In order to solve the problem ofrapid field failure analysis and diagnosis for new-type construction machinery, the expert- based fault diagnosis system is developed. Its functions include two parts of maintenance decision and repair guide as well as main- tenance teaching and training. The hardware is mainly composed of personal computer, whereas the software is made up of the PDA module used for information detection, fault diagnostic expert module, maintenance selection and concept module, training and teach- ing module, aiding module and printing ＆ output module. The development of the system can greatly improve the fault diagnosis and maintenance ability.
