There are a Smart Verify device, the Smart Verify device can automatically judge described exhale for the outer surface of the respirator
Whether haustorium has already appeared exception, if occur it is abnormal if issue alarm, wherein it is shown to examine that specific step is as follows:
There are a sound collection apparatus, sound pretreatment unit and abnormal test devices in the Smart Verify device；
Firstly, the sound collection apparatus obtains the sound of the respirator of predetermined time period at work, and will be described
Sound is passed to the sound pretreatment unit；
The sound pretreatment unit counts the totalframes P of the incoming sound of the sound collection apparatus, and obtains each frame
The value of first audio and the second audio simultaneously forms matrix A, and matrix A is the value that P row 2 arranges, and brings matrix A into formula (1), is done
Rejecting is disturbed, obtains rejecting matrix B；
Wherein, Bi,tFor the value that the i-th row t of matrix B is arranged, that is, to Ai,tValue after carrying out interference rejecting, Ai,tFor matrix A
The value of i-th row t column, Π is pi, and e is natural constant, i=1,2,3 ... P, t=1,2；
The matrix B is brought into formula (2), adjustment factor is calculated；
rtTo solve the adjustment factor that the t of obtained matrix B is arranged, t=1,2；
Then, sound pretreatment vector C is obtained using formula (3)；
Wherein, CiFor i-th of value of vector C, SiFor intermediate parameters, Bi,1For the value that the i-th row the 1st of matrix B arranges, Bi,2For matrix B
The i-th row the 2nd column value, min () be solve bracket in minimum value, max () be solution bracket in maximum value, i=1,2,
3…….P；
Sound pretreatment vector C is passed to the abnormal test device；
In the abnormal test device, there are preset inspection vector D, the number of the value among the vector D is P, by institute
It states vector C and vector D and brings formula (4) into and obtain inspection result；
Wherein, the inspection result that rt is, DiFor i-th of value of vector D,
If the rt is greater than 0.5, illustrates that respirator has already appeared exception, then issue early warning, illustrates if rt is less than or equal to 0.5
There is not exception in the respirator.
