1. A method for synchronizing sensor detection in a moving conveyor belt system of the system type having a plurality of sensors spaced along the belt and a sensor reader for detecting and identifying the presence of a sensor passing by the sensor reader, and a plurality of identification tags spaced along the belt and a tag reader for detecting and identifying the presence of a tag passing by the tag reader, the method comprising:

  • acquiring associated time and distance target values from a calibration table for a next sensor (S1) based upon a detected and identified functional tag;

    initiating time and distance counters;

    determining whether the next sensor (S1) is detected within the time and distance target values.
