Description
Technical field
The invention belongs to the field of medical instrument technology more particularly to a kind of new-type surgical nursing dressing change device, control systems
And control method.
Background technology
Currently, the prior art commonly used in the trade is such：
Currently, the drug being applied with removes old drug after reaching defined usage time, it will be new
Drug applies, to ensure the validity of drug.General old drug and new drug are same drugs.Or using a kind of or several
Kind of drug, because of needs (such as have reached curative effect, or find there is better healing scheme) medically, be changed to other one kind or
Several drugs.Dressing process is one and its important process, and the process of dressing directly affects the process for the treatment of.Nowadays do not have
Have a kind of time saving well, and liquid is uniformly coated on to the dressing change device on wound.
The Dispersion Equation of wave is generally a binary transcendental equation about wave number and frequency, when solving in complex wave number field
When the solution of disperse relationship, equation becomes more complicated ternary transcendental equation, and the coefficient of Dispersion Equation is possible to contain plural number
, thus such issues that solution it is highly difficult.
In conclusion problem of the existing technology is：
Nowadays without a kind of time saving well, and the dressing that liquid is uniformly coated on wound fills
It sets；Meanwhile existing apparatus cannot detect whether liquid leaks in dressing；And detection bacterium data are unable to, it has a single function,
Poor practicability.
Can only generally disperse relationship be solved to the case where extremely special very simple, this is for various different structures
The analysis of sonic sensor is far from being enough.
In recent years, have scholar to carry out the carrier frequency estimation of single CF signal under Alpha Stable distritation noise models
Certain research, but its achievement in research is less.Grandson et al. proposes to be based on fractional lower-order statistics, it is proposed that one kind is suitable for
The new spectral analysis method of Alpha Stable distritations.This method is composed using fractional lower-order covariance, to whole value ranges (0 ＜ α
≤ 2) signals with noise carries out frequency-response analysis, and proposes weighting and overlap method of average estimated score low order covariance spectrum.It should
Method is all suitable for any one α value, and the variance of Power estimation is smaller.But in the document there is no to carrier frequency estimate to
Go out specific algorithm steps, carrier frequency can just be estimated by still needing to further investigate its covariance spectrum.Zhao et al., which is directed to, is based on second order
The problem of method for parameter estimation of Cyclic Statistics is seriously degenerated in Alpha Stable distritation noises, it is proposed that one kind is based on dividing
The mpsk signal carrier frequency estimation method of number low order Cyclic Spectrum analyzes its carrier frequency for the psk signal under different M values
With the relationship of corresponding scores low order Cyclic Spectrum parameter, the estimating carrier frequencies of suitable all psk signals are given on this basis
Method.This method is when mixing signal-to-noise ratio is -10dB and α is 1.5, the normalized mean squared error of the carrier frequency estimation of bpsk signal
Normalized mean squared error for the estimation of 0.043, QPSK signal carrier frequency is 0.041, therefore the carrier frequency under low signal-to-noise ratio estimates performance
It is still to be improved.
