Problems solved by technology

However, if an anomaly occurs in a vehicle after it has already been shipped, the anomaly evaluation device must be transported to the location where the vehicle to be inspected is located
For this reason, if an anomaly evaluation unit is upgraded to accommodate large amounts of data as judgment criteria for greater accuracy, it is sometimes inconvenient to ship such an upgraded unit

Abstract

An abnormal sound evaluation system according to this invention includes a sound recording device for recording a sound generated from equipment at a location adjacent the equipment, and an abnormal sound evaluation device for evaluating the sound recorded, wherein: the sound recording device includes sound data conversion means for converting the recorded sound into digital sound data, and sound data output means for outputting the digital sound data thus converted for the abnormal sound evaluation device; and the abnormal sound evaluation device includes sound data input means for receiving the digital sound data, and abnormal sound evaluation means for evaluating the sound as to abnormality based on the digital sound data inputted and outputting a conclusion of the evaluation including abnormality information about the equipment.

Description

technical field [0001] The present invention relates to an abnormal sound evaluation system, which is installed on a certain vehicle to evaluate the abnormal sound produced by equipment such as vehicles or engines when abnormalities occur. The present invention also relates to a sound recording device suitable for this system and an abnormal sound evaluation device. Background technique [0002] So far, when an engine in a vehicle such as a car has an abnormality or a malfunction, it has been conventional to evaluate the abnormality or malfunction based on the abnormal sound produced by the engine. Usually, a technician will go to a car dealership or a car repair shop where the (faulty) vehicle is sent, for example, to conduct an abnormal assessment based on the abnormal sound by listening to the abnormal sound on site. In this case, if the evaluation cannot reach a conclusion, then the information on the abnormal sounds that have been collected so far is searched for a des...
