<P>PROBLEM TO BE SOLVED: To enable information from an arbitrary point of the surface of a moving body to be safely acquired, to secure reproducible information by accurately converting the acquired information into an electric signal without being affected by ambient noise, and to perform objective abnormality diagnosis of the moving body on the basis of the information. <P>SOLUTION: An abnormality diagnostic device for a moving body comprises: a contact part 1 which can be brought into contact with an arbitrary point of the surface of a moving body M; a contact material 2 which can transmit a sound from the contact part 1; an acoustic sensor 3 disposed in a part of the contact material 2; an electrically insulating resin shield part 4 which fixes the acoustic sensor 3 to the contact material 2 and shields external disturbance; a converter 6 which converts the output of the acoustic sensor 3 into an electric signal; and an arithmetic processing part 7 which performs storage/calculation of the output of the converter 6 and determines abnormality of the moving body M on the basis of the output. <P>COPYRIGHT: (C)2013,JPO&INPIT |
