Modeling an interpretation of real time compaction modeling data from multi-section monitoring system

摘要

A method, apparatus and computer-readable medium for determining deformation of a plurality of coupled members. A distributed strain sensor string on a first member is coupled to a distributed strain sensor string on a second member. Signals are obtained from the sensor strings. A subset of strain data relating to sensor strain on the first member and the second member is created. A virtual sensor string is created having a plurality of virtual sensors placed on the first and second members including a joint therebetween. Strain data of sensors in the distributed stain sensor strings is mapped to sensors in the virtual sensor string. The deformation of the plurality of coupled members is determined using the strain data of the virtual sensors.

1. A method of determining a deformation mode of coupled first member and second member, comprising:
coupling a first distributed strain sensor string on the first member to a second distributed strain sensor string on the second member; propagating light through the first distributed strain sensor string and the second distributed strain sensor string to obtain strain data from sensors in the first distributed strain sensor string and sensors in the second distributed strain sensor string; creating subset strain data from the obtained strain data; creating a virtual sensor string on the first and second members including a joint therebetween, the virtual sensor string including a plurality of virtual sensors; continuing a wrap mode from the first distributed strain sensor string to the virtual sensor string; determining a phase shift between an azimuthal angle of the subset strain data and an azimuthal angle of the virtual sensor string; using the subset strain data and the phase shift to determine virtual strain data at the plurality of virtual sensors in the virtual sensor string; and determining the deformation mode of the coupled first member and second member using the virtual strain data.
