Title: (DE) Mehrkanalige Ultraschall-Messeinrichtung
(EN) Ultrasonic-measuring device for motor vehicle, has control unit to transmit and receive generated low frequency ultrasonic signals and to measure high frequency body impact signals to measure running time in gaseous medium
Abstract: front page image
(DE)

Die vorliegende Erfindung betrifft eine Ultraschall-Messeinrichtung mit einer zentralen Steuereinheit, die mehrere Kanäle für den Anschluss von Ultraschallsensoren zur Abgabe und/oder zum Empfang von Ultraschallsignalen aufweist und die eine programmgesteuerte Ultraschallelektronik mit zumindest einem Signalgeber für die Ansteuerung der Ultraschallsensoren zur Abgabe der Ultraschallsignale sowie einer Auswerteeinheit für die Auswertung von Empfangssignalen der Ultraschallsensoren umfasst. Die zentrale Steuereinheit ist für die Erzeugung und den Empfang von niederfrequenten Ultraschallsignalen für Laufzeitmessungen in gasförmigen Medien über Messungen von Körperschall bis hin zu hochfrequenten Ultraschallsignalen für Laufzeitmessungen in flüssigen Medien mit den Ultraschallsensoren ausgebildet. DOLLAR A Mit der vorliegenden Ultraschall-Messeinrichtung lassen sich mit einer einzigen Steuereinheit die unterschiedlichsten Messaufgaben durchführen, insbesondere vielfältige Messaufgaben in einem Kraftfahrzeug.


(EN)

The device has a control unit (1) with measuring channels for connection of ultrasonic sensors (2) to transmit and receive generated low frequency ultrasonic signals. The unit (1) has an analyzing unit with a transmitter to control the sensors to evaluate the reception of the signals of the sensors. The unit (1) measures high frequency body impact signals to measure running time in gaseous medium. - The ultrasonic sensors are arranged in an ultrasound transducer and sense a task e.g. impact sound measurement.
