Abstract

A data processing system automatically maintains records of respective locations of a plurality of objects in real time. Each of the objects has secured thereto a respective object marker (54) which transmits an identification signal that is unique to the respective object.
Sensor devices (52, 58) are installed at respective doorways of a building.
Each sensor device receives the identification signal transmitted from the object marker as the respective object is moved through the doorway.
The sensor device detects from the identification signal a direction in which the object is being moved through the doorway and generates a detection signal indicative of the detected direction of movement and also indicative of the identification signal for the object. The data processing system (66) receives the detection signals from the sensor devices and maintains a data record with respect to each of the objects indicating the present location, in the building, of each of the objects.
