Abstract
An optical fiber sensor system and a method for determining a location of a disturbance having a signal processor with a plurality of activation cells adapted to react to components of a back-scattered signal and label the disturbance.
Claims16
An optical fibre sensor system comprising:
- an optical fibre;
- a radiation source for launching radiation into the optical fibre;
- a detector for detecting back-scattered radiation back-scattered from the optical fibre;
- and
- a signal processor connected to the detector for generating a plurality of values from the back-scattered radiation, the signal processor comprising:
- a plurality of first activation cells of a machine learning model, the plurality of first activation cells connected to the signal processor and configured to receive a plurality of components of the back-scattered radiation;
- a plurality of second activation cells of the machine learning model, overlapping subsets of the first activation cells being connected to ones of the second activation cells;
- and
- an output for summing at least outputs from a subset of the plurality of second activation cells to produce a result indicative of at least one interference with the optical fibre.

A method for determining a location of a disturbance, the method comprising:
- launching radiation into an optical fibre;
- detecting back-scattered radiation;
- processing the back-scattered radiation to produce a plurality of components;
- passing the plurality of components to a plurality of first activation cells within a machine learning model;
- triggering first outputs from the first activation cells;
- passing the first outputs to a subset of second activation cells within the machine learning model;
- triggering second outputs from the subset of the second activation cells;
- summing the second outputs from a plurality of subsets of the second activation cells;
- and
- calculating, by a programmable processor associated with the machine learning model, the location of the disturbance based on a change in a frequency of the summed second outputs.
