| Abstract: Compressed air is a widespread but costly energy carrier. Leaks account or 10 compressed air consumption in production facilities and their emoval offers high potential for cost reduction. The turbulent flow rom a leak causes broadband acoustic emissions. These are exploited or leak detection using a narrowband ultrasonic microphone that s insensitive to audible noise. A parabolic mirror or an acoustic orn is utilized to enhance the directivity and the received signal ower of the microphone. The microphone is mounted on mobile service obots. In the project "Robotair" an automated guided vehicle (AGV) nd a remotely controlled micro aerial vehicle (MAV) were used for obotized inspection of production facilities. In order to detect eaks, predefined areas are scanned. A leak is detected and localized ased on the sensed peak amplitude of the ultrasound signal. The orresponding pose of the sensor facing the leak is determined based n the selflocalization of the robot. Leak localization is carried ut by triangulation of two sensor poses. Tests were conducted in n automobile production facility to evaluate the performance of he system. A leak was placed in an assembly line and multiple measurements ere taken from two positions with the AGV and the MAV. The leaks ere successfully detected and localized. |
