| Abstract: | Big diesel engine is one of the most important equipments in industry, and its safety condition plays a great role in oil production. This paper presents a fuzzy method to monitor the safety state of the big diesel. Six useful diagnostic characteristic parameters have been selected to diagnose safety condition of the big diesel engine. The standard fuzzy vector was obtained by using statistical method, so the status of big diesel's safety condition can be determined by calculating the fuzzy distance between the fuzzy vector and standard fuzzy vector. This fuzzy method has been successfully used on PZ12V190 diesel engine. |
