MULTICHANNEL Acoustic emission systems for diagnostics of automotive engineering

摘要

The invention relates to the field of technical diagnostics and nondestructive inspection of objects on the acoustic emission signals and is used for evaluation of technical status of hazardous industrial facilities, as well as in the automotive industry.; Technical result is directed to the development of a multi-channel acoustic emission system for the diagnosis of motor vehicles, which will produce diagnosing motor vehicles, located at a distance from the external power supply by means of on-board vehicle network.; The technical result is achieved in that said multichannel acoustic emission system for the diagnosis of motor vehicles comprising a power supply for providing power devices for recording and processing acoustic emission signals through the cable line measurement data, the power control device, wherein it is further provided with a converter electric current energy.; The distinguishing features of the prototype is that multi-channel acoustic emission system for the diagnosis of motor vehicles provided with a further energy converter of the electric current.; The proposed technical solution allows multi-channel acoustic emission system to operate autonomously and makes it possible to produce a diagnosis of motor vehicles located at a distance from the external power supply with the help of the onboard vehicle network.
