Detection system for determining positional and other information about objects |
| abstract |
A system for tracking the position of each of a plurality of labelled objects 10 in a specified environment by determining the transit time of ultrasound signals transmitted from a transmitter on each labelled object, to a plurality of ultrasound receivers 20-26 positioned at fixed points in or around the specified environment, and computing therefrom the distance of the transmitter from the receivers. The ultrasound transmissions are initiated by radio signals from a master transmitter 16 and each of the objects includes a radio receiver adapted to respond to the radio transmissions to initiate a burst of ultrasound. Each ultrasound transmitter/radio receiver combination on an object is referred to as a transponder. In order to allow the system to adapt to different numbers of transponder-transmitters and differing demands for service (eg frequency of position determination per transponder-transmitter), a coordinating control system is provided for determining the order in which the object mounted transponder-transmitters are to be triggered by the radio transmissions, in response to updatable information relating to the objects and related service demands. The control system may include a memory for storing relevant information about the different transponders with reference to their radio addresses, by which the order can be determined. The system can also be used to determine object orientation by monitoring the positions of two transmitters at spaced apart locations on an object and comparing their positions. It is preferable to address the two or more transmitters on the object in succession. |
