摘要： The invention relates to technical diagnostics. The claimed method consists in measuring of vibration acceleration in three mutually orthogonal planes with the use of vibration sensors mounted at the monitoring points on a diesel generator. Vibration accelerations are measured at the monitoring points on an operational and knowingly fault-free diesel generator, and then vibration accelerations are measured at the monitoring points of a diesel generator in the course of its operation with prescribed intervals. Temperature and intensity of an ultrasonic signal are additionally measured at the same monitoring points, and the root mean square values of the ultrasonic signal intensity, temperature and vibration acceleration are determined. On the basis of the measured vibration acceleration values the root mean square values of vibration velocity and vibratory displacement are calculated, the distances between clusters of preceding measurements are determined, and a conclusion on the operating state of the diesel generator is made. The technical result consists in allowing the timely detection of any operating defects in a diesel generator by performance of periodic measurements and comparison of the obtained calculation results with each other, thus also providing for safety of the process equipment in plants.

摘要： There is provided a method of specifying a location of occurrence of an abnormal sound, the method including: storing mapping data in a storage device (83), the mapping data prescribing mapping that receives, as inputs, a sound variable that matches a sound detected in a vehicle and a state variable of a drive-system device of the vehicle synchronized with the sound, and that outputs a location as a main cause of the sound; executing a sound signal acquisition process of acquiring a sound signal output from a microphone (65) that detects a sound; a state variable acquisition process of acquiring the state variable of the drive-system device; and a specifying process of specifying the location of occurrence of the sound corresponding to the sound signal using the sound variable and the state variable as inputs to the mapping. There are also provided a non-transitory storage medium and an in-vehicle device.
