Abstract
A net monitoring system, including: a plurality of net monitoring devices, each net monitoring device including: a housing; a plurality of tensioning arms, each tensioning arm reversibly extendable through the housing and configured to reversibly secure to a net, each tensioning arm including a force sensor configured to generate a tension signal indicative of a tension applied to the corresponding tensioning arm; a tensioning mechanism configured concurrently retract the plurality of tensioning arms into the housing; an impulse generating device, configured to generate an impulse responsive to a command; and a communications device configured to receive the tension signals from the plurality of force sensors, and transmit the tension signals through water; and a controller, configured to: command at least one of the plurality of net monitoring devices to generate the impulse; receive the tension signals responsive to the command to generate the impulse; and determine, based on the received tension signals, a presence of a defect in a net on which the plurality of net monitoring devices are installed.
