Abstract
A Shipboard Auditory Sensor (SAS) for detection and classification of acoustic signaling at sea is capable of detecting whistles blasts from other vessels in accordance with Rules 34 and 35 of COLREGS to support autonomous operations in a maritime environment.
Claims20
An autonomous vessel comprising:
- a shipboard auditory sensor system for processing audio signals from one or more surface maritime vessels in a vicinity of the autonomous vessel to support autonomous navigation of the thereof, where the shipboard auditory sensor includes an auditory sensor assembly configured to
- receive audio signals from the one or more surface maritime vessels in a vicinity of the autonomous vessel,
- filter the received audio signals to determine if the received audio signals are in a first auditory range specified by one or more regulations and being indicative of a status of the one or more surface maritime vessels, and
- format audio signals determined to be in the first auditory range into audio data packets to support autonomous navigation of the autonomous vessel.
A shipboard auditory sensor system located on a first maritime vessel for processing audio signals from one or more additional maritime vessels in a vicinity of the first vessel to support navigation thereof, the shipboard auditory sensor system comprising:
- an auditory sensor assembly including a microphone sensor array for sensing audio signals from the one or more maritime vessels, the auditory sensor assembly including a microphone array housing having a top and bottom plate separated by multiple spacers with the microphone array affixed to an inside facing surface of one of the top and bottom plates;
- wherein the microphone array includes multiple individual microphone assemblies, each of the individual microphone assemblies including a microphone housing with a pre-amplifier and a microphone therein.
An auditory sensor assembly for sensing audio signals from one or more maritime vessels to assist a primary maritime vessel with navigation, the auditory sensor assembly comprising:
- a microphone array housing having a top and bottom plate separated by multiple spacers;
- a microphone array affixed to an inside facing surface of one of the top and bottom plates, wherein the microphone array includes multiple individual microphone assemblies, each of the individual microphone assemblies including a microphone housing with a pre-amplifier and a microphone therein;
- a filter and a data acquisition board attached to the microphone array housing, wherein the sensed audio signals are determined by the auditory sensor to be in a first specified auditory range and are indicative of a status of the one or more maritime vessels, said status being useful for assisting the primary maritime vessel with navigation.
