<p><P>PROBLEM TO BE SOLVED: To facilitate prevention and maintenance of a carrier or a traveling route by accurately recognizing the state of the carrier or the traveling route including the circumstances of the traveling route such as a diverging point or a merging point. <P>SOLUTION: In this carrier system, a vibration sensor or a torque sensor or the like is mounted on a carrier 5, and abnormality data are transmitted to a carrier controller 10. The carrier controller 10 stores the abnormality data for each segment and each carrier, and the abnormal segment and carrier on the traveling route is specified from whether or not abnormal data are acquired from a plurality of carriers in the same segment, or whether or not abnormal data are caused from the carriers even in a normal segment. Consequently, it is possible to check the states of both the traveling route and the carrier, and to decide which of the traveling route and the carrier has a problem. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
