Abstract
A method for monitoring a system, in which a plurality of acoustic images are recorded and compared at defined intervals of time over a period of time extending several weeks. A large system can be monitored reliably and with little complexity if the acoustic images each contain a plurality of acoustic image areas which are arranged in a spatially different manner, and, between respective recordings of the image areas of an acoustic image, an acoustic sensor is aligned with an image area, which is to be recorded, of a next image area by being moved.
Claims12
A method for monitoring a system, which comprises the steps of:
- recording and comparing a plurality of acoustic images at defined intervals of time over a period of time extending several weeks, the acoustic images each contain a plurality of acoustic image areas which are disposed in a spatially different manner, and, between respective recordings of the acoustic image areas of an acoustic image, an acoustic sensor is aligned with an image section, which is to be recorded, of a next image area by being moved.
An apparatus for monitoring a system, the apparatus comprising:
- an acoustic sensor;
- a process unit for controlling a recording of a plurality of acoustic images and performing a comparison of the acoustic images at defined intervals of time over a period of time extending several weeks;
- and
- a movement device for moving said acoustic sensor, the acoustic images each containing a plurality of acoustic image areas which are disposed in a spatially different manner, and said process unit being intended to control a movement of said acoustic sensor between respective recordings of the acoustic image areas of an acoustic image such that the acoustic sensor is aligned with an image section, which is to be recorded, of a next image area.
