Calibration and operational assurance method and apparatus for RFID object monitoring system
A method for monitoring objects in a three dimensional target area and or business process decision making. The methods include calibration, recalibration, operation and rules compliance for a radio frequency object monitoring system. Location tags are placed throughout a three dimensional area in predetermined positions and used to determine relative position, movement and or distances of objects with and without object tags. Repeated scanning and comparison of data provides a database by which the object monitoring system responds according to predetermined rules.
1. A method of rules compliance for an object monitoring system, comprising steps of:
assigning a value to each of a plurality of object tags;
the object monitoring system monitoring a relative position of the plurality of object tags in comparison with a position of a plurality of location tags;
the object monitoring system provided with a set of predetermined rules; the predetermined rules including recognizing the values of the object tags;
and the object monitoring system initiating an alarm when the object tags move in relation to the location tags according to the predetermined rules; the object monitoring system providing a surveillance response to moving object tags proportional to the values of the object tags; wherein the predetermined rules specify an action when the object tags approach within a predetermined distance from a zone.
2. The method of claim 1 , further including monitoring a predetermined distance between designated object tags and initiating a predetermined response upon detection of the predetermined distance that is less than a predetermined value.
