Operation managing system for driving a navigation control device according to a degraded operating mode

摘要

An operation managing system is provided for managing the operation of a navigation control device. The navigation control device is adapted for controlling the depth and/or the lateral position of a towed acoustic linear antenna and including a body to which is attached a set of wings. The operation managing system operates the navigation control device according to a degraded operating mode, by acting on at least one non-released and motorized wing when detecting that at least one wing of the set of wings has been released or must be released.

1. An operation managing system for managing operation of a navigation control device, the navigation control device being adapted for controlling depth and/or lateral position of a towed acoustic linear antenna and comprising a body to which is attached a set of wings, the operation managing system comprising:
means for detecting that at least one wing of the set of wings has been or is released, said means for detecting comprising a wing loss decision circuit, configured to generate a wing loss signal when detecting that at least one wing of the set of wings has been or is released; and means for operating the navigation control device according to a degraded operating mode, by acting on at least one non-released and motorized wing when the means for detecting detects that at least one wing of the set of wings has been or is released, said means for operating comprising a driving circuit comprised in the navigation control device and configured to drive the navigation control device according to said degraded operating mode when receiving said wing loss signal, said degraded operating mode enabling to control at least the depth of the towed acoustic linear antenna, wherein said at least one wing that has been or is released comprises an embedded magnet, wherein said operation managing system comprises a magnetic sensor, for measuring a whole magnetic field, and wherein said wing loss decision circuit comprises: a circuit configured to detect a change in the measured whole magnetic field, due to a movement away of the embedded magnet when said at least one wing is released; and a circuit configured to generate said wing loss signal, when said change in the measured whole magnetic field is detected.
