<P>PROBLEM TO BE SOLVED: To perform smooth production management even in the case of a process return. <P>SOLUTION: When a worker 100 passes through an antenna gate 1, a plurality of detectors 2a-2d detect the worker 100 who is a passing person of the gate antenna 1, and an RFID reader/writer 50 reads, through the gate antenna 1, a product ID recorded in an RFID tag 9 attached to a product 9 which is transferred to the following process when the worker 100 passes through the gate antenna 1. The process management device 30a detects the passing direction of the worker 100 passing through the gate antenna 1 based on the detection state of each detector 2a-3d, manages transfer state data showing the transfer state to the following process for each product ID based on the detected passing direction, and transmits the managed transfer state data to a center server for each product ID. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
