<P>PROBLEM TO BE SOLVED: To provide a part monitoring system to monitor whether or not parts placed in a working machine are legitimate and prevent imitations from being used. <P>SOLUTION: A working machine 2 has a plurality of replaceable parts 4, and each part 4 is provided with a radio tag 5. The radio tag 5 stores a part ID in advance. When the working machine detects a part replacement or a start of an engine (2A), the part ID stored in the radio tag 5 is acquired (2B) and transmitted to a working machine management device 1. The working machine management device 1 collates the part ID received from the working machine 2 with a part ID stored in part ID storage means 1C (1A). If the two part IDs do not match, abnormal state detection means 1B outputs an alarm signal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
