Method and system for locating an instrumented object transported along a path by a conveyor machine

A system for locating an object transported along a path by a conveyor machine, comprising:

• an instrumented object provided with a measurement system configured to measure at least one given physical quantity during the transportation of the object along the conveyance path, and configured to measure the time evolution of the physical quantity measured by the measurement system having a sensor on the object during the transportation of the object along the conveyance path, and
• an external analysis device comprising
• a recognition module configured to recognize a plurality of indicia during the transportation of the object along the conveyance path, each indicium corresponding to a path characteristic in the time evolution of the measured physical quantity measured by the measurement system,
• a module configured to determine during the transportation of the object along the conveyance path a timeline of path characteristics corresponding to a sequence of recognized indicia based on the recognizing of the plurality of indicia by the recognition module, and
• a locating module configured to locate the object during the transportation of the object along the conveyance path based on a correspondence between the determined timeline of path characteristics and a predetermined spatial representation relating to the conveyor machine stored in memory,
• wherein the physical quantity is selected from the group consisting of a magnetic field, a temperature, a sound, and a pressure.

An analysis device intended to locate an instrumented object transported along a path by a conveyor machine, the instrumented object being provided with a measurement system for measuring at least one given physical quantity, arranged for measuring the time evolution of the physical quantity during the transportation of the object along the conveyance path, the analysis device comprising:

• a communication interface configured to communicate, during transportation of the object along the conveyance path, with the measurement system having a sensor on the object and to receive from the measurement system measured data relating to the time evolution of the physical quantity during the transportation of the object along the conveyance path,
• a recognition module configured to recognize a plurality of indicia during transportation of the object along the conveyance path, each indicium corresponding to a path characteristic in the time evolution of the measured physical quantity received from the measurement system during transportation of the object along the conveyance path,
• a module configured to determine during transportation of the object along the conveyance path a timeline of path characteristics corresponding to a sequence of recognized indicia based on the recognizing of the plurality of indicia by the recognition module, and
• a locating module configured to locate the object during the transportation of the object along the conveyance path based on a correspondence between the determined timeline of path characteristics and a predetermined spatial representation relating to the conveyor machine stored in memory,
• wherein the physical quantity is selected from the group consisting of a magnetic field, a temperature, a sound, and a pressure.
