Abstract:
According to the status o f eng ine used, fault d iagnosed and inspected in production, a set of inte-l ligent fault d iagnosis and inspection system based on the sound intensity recogn ition was deve loped. Thewho le project was given and its principlew as stud ied systematica lly by analyzing the system requirements and def-i n ing the rules. The software to be used in processing data, diagnosing faults and controlling w as developed. Several key prob lems were d iscussed in the process of developing the so ftwares. The prob lems include know-l edge base establishmen,t the intelligent fault d iagnosismodel design and input /outputmode describption. The so ftware and hardware p latform is g iven for intelligent fault diagnosis for engine in practice.
