Description
Technical field
The invention belongs to sound phase instrument technical field more particularly to a kind of simulation human auditory system effect sound phase instrument detection methods.
Background technique
Sound phase instrument also known as acoustical camera are to utilize the dedicated of a certain range of sound-filed simulation of Microphone array measurement
Equipment can be used for measuring the position of the sound of object sending and the state of acoustic radiating, and be shown intuitively with cloud atlas mode
The measurement of image, i.e. acoustic imaging.
Acoustic imaging (acoustic imaging) is based on Microphone array measurement technology, by measurement certain space
Sound wave reaches the signal phase difference of each microphone, and the position of sound source is determined according to phased array principle, measures the amplitude of sound source,
And sound source is shown in a manner of image in the distribution in space, i.e. acquirement space sound-filed simulation cloud atlas-ultrasonogram, wherein with image
Color and brightness representative voice power.The video image that ultrasonogram is clapped in fact with the camera shooting being equipped on array is with transparent
Mode be superimposed together, be formed the noise source situation that can intuitively analyze measured object sound field in real time.This utilization acoustics,
Sound mapping can be helped people intuitively to recognize by the technologies such as electronics and information processing at the technology of the visible image of human eye
Know sound field, sound wave, sound source, easily understands position and reason that mechanical equipment generates noise, react its sound field being presently in
State.
Therefore, a kind of simulation human auditory system effect sound phase instrument detection method is invented to be very necessary.
Summary of the invention
In view of the above technical problems, the present invention provides a kind of simulation human auditory system effect sound phase instrument detection method.
A kind of simulation human auditory system effect sound phase instrument detection method, which is characterized in that the simulation human auditory system effect sound phase
Instrument detection method includes that acoustical signal is collected, acoustical signal data are transmitted, the identification of failure acoustic image library, comparative analysis, output line failure generation
Code, voice reminder；Under conditions of mechanical equipment continuous normal table work, failure acoustic image identification library is established, to sonoscope reality
When the acoustical signal of mechanical equipment that acquires collect, and the noise data transmission of collection to failure acoustic image is identified into library, acoustical signal and
Failure acoustic image identifies comparative analysis in library, if identifying successfully, exporting output line fault code and carrying out the voice of fault code
It reminds.
Preferably, mechanical equipment line spectrum identification library includes the corresponding line spectrum of mechanical equipment noise spectrum.
Preferably, acoustic imaging fault detection system can use under conditions of any complex sound field.
Preferably, function includes voice broadcast fault code and failure prompting function.
Compared with prior art, the invention has the following beneficial effects: the configuration of the present invention is simple, set using of the invention
