SOUND INFORMATION ACQUISITION SYSTEM, SOUND INFORMATION ACQUIRING DEVICE, NONCONTACT DIAGNOSIS SYSTEM, AND NONCONTACT DIAGNOSIS METHOD

摘要

PROBLEM TO BE SOLVED: To provide a precise and efficient sound information acquisition system and a noncontact diagnosis system.;SOLUTION: The sound information acquisition system for acquiring sound information for diagnosing whether a diagnosis target is normal or abnormal comprises a storage that is provided corresponding to each diagnosis target and stores information peculiar to each diagnosis target in advance; and a sound information acquisition device, having a peculiar information reading section for reading peculiar information from the storage, a reference distance acquisition section for acquiring reference distance from the diagnosis target when acquiring sound information, based on the peculiar information of the diagnosis target, an actual distance measurement section for measuring actual distance from the diagnosis target, a comparison section for comparing the actual distance RL with the reference distance SL, a sound signal detection section for detecting a sound signal, an output section for outputting the comparison result when it is determined that RL is equal to or smaller than SL by the comparison section, and a sound information acquisition section for acquiring the sound signal detected by the sound signal detection section as sound information for diagnosis, when the comparison result of RL≤SL is outputted from the output section.;COPYRIGHT: (C)2006,JPO&NCIPI
