US 7,411,865 B2 · System and method for archiving data from a sensor array

Abstract

A system and method for archiving and retrieving information from an array of remote sensors. In a preferred embodiment the invention is incorporated in a gunshot detection and location system to preserve audio information surrounding a gunshot event for later review or analysis. In a preferred embodiment the system includes a plurality of acoustic sensors deployed in an array, a computer for processing gunshot information from the sensors, and a mass storage device for temporary archival of audio information. When a gunshot event is detected, the location of the audio information of the data within the spool is stored in an index to facilitate later retrieval of the information.

Dependent claims

A method for archiving audio information in a gunshot detection system of a type having array of acoustic sensors placed over a geographic area;

wherein said array of sensors detects gunshots which occur proximate to the array, the method comprising the steps of:
providing a mass storage device;
periodically sampling an audio signal from each sensor;
detecting an impulsive noise event including a start time;
storing samples of audio data in said mass storage device wherein audio signals detected by each sensor can be selected using time data, wherein the audio signals may be reproduced with the relative timing between the audio signals of each sensor preserved;
and
creating a searchable database wherein audio signals containing the impulsive noise event are indexed, with each audio signal being indexed as a function of a sensor that detected the audio signal and the start time.
