Applying RFID hand-held device for factory equipment diagnosis

This paper proposes a new hand-held device application that incorporates an RFID with monitoring system with a fuzzy-rule-based inference into a hand-held device. The designed process follows: firstly, the machine status is displayed in the monitoring system, and when the machine has some problems, PDA users are informed; then, the PDA users can obtain information from the tags by PDA reader and use the fuzzy rules to infer the reasons of breakdown and which part of this machine should be repaired. By means of that the breakdown machine can be repaired immediately when PDA users are informed. After repairing the machine, the new rule is transmitted to other PDA users and central database by replication. This paper shows that applying RFID hand-held device in factory equipment diagnosis can make a big increase on work efficiency.
