Description
Technical field
The invention belongs to electronic communication technology fields, more particularly to a kind of intercommunication panel self checking method.
Background technique
Intercommunication panel detection in the prior art is realized by the hardware check function of panel, and this method is only
There is when some hardware component damages completely to work competence exertion act on, and when there are abnormal conditions for some components, such as want
It is the microphone of panel or when minor failure occur in loudspeaker, equipment is still working, and the self-checking function of hardware can not detect
Out, to drastically influence conversational quality, or even in significant instant influence call, being for this problem prior art can not
It detected, and also there is no very good solution method.
Summary of the invention
The present invention provides a kind of intercommunication panel self checking methods, solve intercommunication panel detection method in the prior art only
The drawbacks of fault condition damaged completely can be detected, and the minor failure that can be still worked normally can not be detected.
Specific technical solution is the intercommunication panel self checking method, acquires normal condition loudspeaker by microphone first and plays
Audio signal, and by collected normal condition loudspeaker play audio signal upload to intercommunication center carry out storage and conduct
Template audio；
Acquisition needs to carry out the audio signal that the loudspeaker of detection moment play, and uploads to the conduct of intercommunication center by microphone
Acquire audio；
Template audio and acquisition audio are converted to frequency domain by time domain by intercommunication center, and calculate separately frequency domain energy spectrum；
By Pearson correlation coefficient calculation formula, acquisition audio and template audio frequency domain energy spectral correlative coefficient are calculated；
It acquires audio and template audio frequency domain energy spectral correlative coefficient is greater than or equal to setting threshold values, determining intercommunication panel just
Often, normal use can still be carried out；It acquires audio and template audio frequency domain energy spectral correlative coefficient is less than setting threshold values, determine intercommunication
Panel is abnormal.
Further, it is less than setting threshold values in acquisition audio and template audio frequency domain energy spectral correlative coefficient, determines intercommunication
After panel exception, alarm signal is issued.
Beneficial effect can detecte out the event for the equipment of minor failure only occur according to the technical solution of the present invention
Barrier problem, testing result is more sensitive and accurate, easy to operate, effectively eliminates equipment fault, guarantees that the operation of intercommunication panel is more steady
It is fixed；It can be effectively by the acquisition audio and template audio frequency after failure by the application of Pearson correlation coefficient calculation formula
Domain energy spectral correlative coefficient distinguishes.
Detailed description of the invention
Fig. 1 is flow chart of the method for the present invention.
Specific embodiment
Equipment fault when being unable to run completely can only be detected for intercommunication panel self checking method in the prior art, and nothing
Method detects minor failure, such as only influences call tone quality, and may continue to the microphone of work or the failure of loudspeaker etc., the application
Concrete scheme is as follows.
Embodiment 1 can will such as be examined as shown in Figure 1, intercommunication centring system executes the self-test of intercommunication panel at a set point in time
Time setting is surveyed in morning 4-6 point, environment is more quiet, and external world's influence is small, and equipment carries out in the case where not using.At the beginning of system
When secondary installation, the confirmation method of template audio can be completed by the following method, choose one section of continuous unremitting voice broadcast
Such as " welcome XXXX self-help bank ", as original audio file；When system is installed for the first time, it is ensured that system is just
Normal, no hardware problem broadcasts the audio file using the loudspeaker (loudspeaker) of panel then under quiet environment；Pass through again
The microphone of panel acquires and uploads to central server and preserves, as template audio file；In order to give original audio
Actual system hardware noise is added in file, so that related coefficient backward is accurately calculated.
Under equipment normal operating condition, also it may be selected before being detected, it is right in the good situation of equipment running status
The center of saying issues broadcasting voice command, and the loudspeaker of intercommunication panel play audio, and will be collected by the microphone of intercommunication panel
Broadcasting audio be uploaded to intercommunication center, this audio is carried out storage and as template audio by intercommunication center.
Followed by daily normal detection, in setting time, intercommunication center issues play command, the loudspeaker of intercommunication panel
Broadcasting audio, microphone acquisition play audio and are simultaneously uploaded to intercommunication center, using this audio as acquisition audio.
Template audio and acquisition audio are converted into frequency domain by time domain using Fast Fourier Transform (FFT) method by intercommunication center,
And calculate separately frequency domain energy spectrum.The calculation method of Fast Fourier Transform (FFT) method and frequency domain energy spectrum is all known method,
This is no longer described in detail.
By Pearson correlation coefficient calculation formula,
Wherein, XiIt indicates the in template audio (i/fft_len) frame
(i%fft_len) energy value of a frequency point,It is the mean value of the frequency domain energy spectrum of template audio, YiIndicate acquisition audio (i/
Fft_len) in frame (i%fft_len) a frequency point energy value,It is the mean value for acquiring the frequency domain energy spectrum of audio, fft_
Len is the frame length of Fast Fourier Transform (FFT), and n=min (nx, ny), nx are the length of the frequency domain energy spectrum of template audio, and ny is to adopt
Collect the length of the frequency domain energy spectrum of audio.
Calculate acquisition audio and template audio frequency domain energy spectral correlative coefficient r；
It acquires audio and template audio frequency domain energy spectral correlative coefficient r is greater than or equal to setting threshold values 0.70 or 0.99
Determine that intercommunication panel is normal, can still carry out normal use；Acquisition audio and template audio frequency domain energy spectral correlative coefficient r, which are less than, to be set
Determine threshold values 0.70 or 0.99, determines that intercommunication panel is abnormal.According to the technical solution of the present invention, it can detecte out and only occur
The failure problems of the equipment of minor failure, testing result is more sensitive and accurate, easy to operate, effectively eliminates equipment fault, guarantees
The operation of intercommunication panel is more stable；It can be effectively by adopting after failure by the application of Pearson correlation coefficient calculation formula
Collection audio and template audio frequency domain energy spectral correlative coefficient distinguish, and keep breakdown judge more accurate.
It is less than setting threshold values in acquisition audio and template audio frequency domain energy spectral correlative coefficient, determines that intercommunication panel is abnormal
Afterwards, alarm signal is issued, alarm issues alarm, so that the failure of staff's intercommunication panel be reminded to tie up
It repairs.
