Device and method for positioning
First Claim
1. A device for positioning of a moving object having a monitoring system and a transponder, attachable to the moving object, which includes an infrared receiver and an ultrasound transmitter, the monitoring system having an analysis unit and at least two sensor units, which are connectable to the analysis unit and include an infrared transmitter and an ultrasound receiver, an infrared trigger signal (IR-TC) able to be emitted, which triggers the emission of an ultrasound signal (US) by the ultrasound transmitter, the ultrasound signal (US) being receivable by the ultrasound receivers and the positioning of the moving object able to be performed by the analysis unit using travel time determination of the ultrasound signal (US).

Abstract
Device and method for positioning of a moving object in a monitorable region (4) using a stationary monitoring system and a transponder (3) attached to the moving object. Furthermore, the monitoring system contains at least two sensor units (2) and an analysis unit (1), which allow distance values (Dx) to be established using travel time measurement of ultrasound signals (US) and positioning to be performed therefrom.

10. A method of positioning a moving object, using a transponder attachable to the moving object and a monitoring system having at least two sensor units, including the following method steps:
-
emission of an infrared signal (IR-TC) by at least one of the two sensor units as a reaction to a start signal (S-TC);
transmission of an ultrasound signal (US) using an ultrasound transmitter, which is part of the transponder, as a reaction to the infrared trigger signal (IR-TC);
transmission of a stop signal (S-US) by each of the two sensor units to a control unit as a reaction to the received ultrasound signal (US);
determination of the time differences between the start signal (S-TC) and the stop signals (S-US) by the control unit;
conversion of the time differences into distance values (Dx) between the transponder and the sensor units, the distance values (Dx) corresponding to the travel times of the ultrasound signal (US); and
determination of the position of the moving object. - View Dependent Claims (11, 12, 13, 14, 15)
