Acoustic fingerprinting of mechanical devices |
摘要 |
A method and device are presented for identifying machines, such as vehicles, based on acoustic machine signatures. An acoustic sensor generates machine-acoustic data about the machine. A machine-signature identifier receives the machine-acoustic data, determines a machine signature from the machine-acoustic data, and identifies the machine based on the machine signature. A machine-signature database, configured to store multiple machine signatures and/or machine-signature templates, may receive and process queries about machine signatures for machine identification. The machine-signature identifier may generate and send an instruction based on the identified machine. The instruction may instruct application of electronic countermeasures or may permit a vehicle to enter a secured area. An acoustic modulator may generate the machine-acoustic data to act as a machine signature. The acoustic modulator may generate the machine signature using an ultrasonic carrier. |

1. A method, comprising:
receiving machine-acoustic data from one or more acoustic sensors; determining, with an acoustic-signature identifier, a machine signature based on the machine-acoustic data, wherein the machine signature is associated with only one individual machine of a plurality of machines; performing, with the acoustic-signature identifier, a complete identification of the individual machine based on the machine signature, wherein performing the complete identification comprises identifying the only one individual machine based on the machine signature; and sending an instruction from the acoustic-signature identifier based on identifying the individual machine. |
