THE POSITION RECOGNITION SYSTEM OF A VEHICLE IN A HARBOR USING A UWB SENSOR

摘要

PURPOSE: A position recognition system of a vehicle in a harbor using a ultra-wide-band sensor(UWB) is provided to recognize the position of a vehicle by respectively installing a UWB tag in the vehicle and a UWB sensor in a harbor terminal. CONSTITUTION: A signal transmission unit(100) is installed in a vehicle and transmits signal. A signal receiving unit(200) receives the signal from the signal transmission unit. The position of the signal transmission unit is calculated through a time difference of arrival. The received signal is transmitted to a position recognition server(300). Considering the speed of the vehicle, the position recognition server filters estimated position data with a speed filter. The filtered position data is displayed on a graphic user interface.
