| Abstract: | According to the status of engine used, fault diagnosed and inspected in production, a set of intelligent fault diagnosis and inspection system based on the sound intensity recognition was developed. The whole project was given and its principle was studied systematically by analyzing the system requirements and defining the rules. The software to be used in processing data, diagnosing faults and controlling was developed. Several key problems were discussed in the process of developing the softwares. The problems include knowledge base establishment, the intelligent fault diagnosis model design and input/output mode describption. The software and hardware platform is given for intelligent fault diagnosis for engine in practice. |
