Fig. 2 is the implementation process figure for the cardioelectric monitor method that the utility model embodiment provides, and details are as follows：
The realization of the cardioelectric monitor method, based on cardioelectric monitor system described in Fig. 1, methods described specifically includes：
In step s 201, the cardioelectric monitor analog signal of user is gathered by electrocardioelectrode.
Specifically, the electrocardioelectrode can be textile electrode, the electrocardioelectrode can by the braided wire of conduction with
Filter circuit is connected.The electrocardioelectrode can be arranged on electrocardio clothing, and user, can be by knitting when dressing the electrocardio clothing
Thing electrode effectively obtains cardioelectric monitor analog signal.
In step S202, the cardioelectric monitor analog signal is filtered, by electrocardiogram integrated chip by the heart
Pyroelectric monitor analog signal is converted to cardioelectric monitor data signal.
The cardioelectric monitor analog signal is filtered, can effectively remove the power frequency in cardioelectric monitor analog signal
Disturb, loop noise of shaking and myoelectricity noise and electrode noise etc..
Wherein, step is filtered to the cardioelectric monitor analog signal including following one or two kinds of：
Potential industrial frequency noise and ringing noise are eliminated by dual bilateral filtering technology and twice iterative technique；
Eliminated by two kinds of parallel noise reductions and disturbed with myoelectricity and electrode noise.
Specifically, described by dual bilateral filtering technology and twice, iterative technique potential industrial frequency noise and shakes to eliminate
Bell noise step includes：
After end effect signal is inputted into the first wave filter, forward filtering is performed, obtains the first forward filtering signal；
Inverse filtering is performed to the first forward filtering signal, obtains the first inverse filtering signal；
The first inverse filtering signal iteration is inputted into first wave filter, performs the forward filtering, obtains the
Two forward filtering signals；
The inverse filtering is performed to the second forward filtering signal, obtains first filter not comprising industrial frequency noise
Ripple signal；
Wherein, first wave filter is according to sample rate, trap frequency and the first resistance band, and original filter
In parameters, first wave filter is calculated.
The dual bilateral filtering technology specific implementation process is as follows：
1. initialize.The resistance band of given sample rate, trap frequency and trapper, filter coefficient is calculated by formula (1).
Wherein, formula (1) is specially：
fsFor the sample rate, f0For the trap frequency, Δ f is first resistance band.
2. first time bilateral filtering.The system for making end effect signal be determined by formula (1), obtains output signal and residual
Part, residual fraction contains potential industrial frequency noise PLI and the loop noise RAs that shakes.This process is filtered equivalent to primary signal
Ripple is twice：It is once from left to right；Another time is from right to left.Because formula (1) is a causal system, same heartbeat pulse letter
RAs caused by number can be located at the both sides of pulse.
3. second of bilateral filtering.Filtering signal is set to obtain output signal again by same system.PLI will in this step
It is filtered out.Residual error portion only includes RAs and the broadband noise in stopband.
4. RAs is positioned.Involve the technologies such as threshold value using difference, low pass filtered to enter the RAs in step 3. middle residual error portion
Row positioning.
5. RAs is eliminated.RAs is eliminated using certain threshold rule, i.e., screens each heart in step 3. middle residual error portion
Not by the coefficient of one end (pulse both ends one end is polluted, and the other end is not contaminated) of RAs pollutions as output in jump pulse.It is actual
On, the distortion for causing output signal to last about several seconds in starting end by the transient effect of system will be also eliminated in this step.
Dual bilateral filtering technology implies an important hypothesis：The resistance band parameter of setting makes each two heartbeat arteries and veins
Rushing RAs caused by signal does not have overlapping, and the technology can not tell overlapping RAs.Actually selected resistance band is inevitable
Meeting cause RAs overlapping.Because civil power power frequency generally has certain drift, the industrial standard of general country be controlled at 1% with
It is interior；But poor civil power environment, drift up to 3%.Double iterative technique can solve this problem.
Iterative technique filtering twice is described below：
1. carry out PLI eliminations using a first larger resistance band.The first larger resistance band of setting one (ratio
Such as 6.0Hz), target signal filter PLI is disturbed using dual bilateral filtering technology.PLI and relatively strong but hold is contained in residual error portion
Shorter RAs of continuous time.
2. carry out signal reconstruct using less second resistance band.Select less second resistance band
(actual conditions requirement is less than 6.0Hz, generally 2.0Hz or so), using dual bilateral filtering technology to upper step (1.) residual error portion
Divide and handled.Obtain exporting filtering part this step and mainly make use of residual error portion than the intensity generally low two of primary signal
Two-stage, the RAs included in residual error portion can be ignored.
It is being using the requirement on the larger and less stopband wide duration and intensity to RAs in iterative technique twice
Complementary.As can be seen that it is Non real-time processing to be eliminated while Hz noise and RAs, but it is (such as therein low by design
Pass filter coefficient is arranged to simple integral coefficient), it can be achieved quasi real time to handle.
Step is disturbed to include with myoelectricity and electrode noise for described eliminated by two kinds of parallel noise reductions：
Parallel one：Decomposed by Empirical mode decomposition and contain noisy intrinsic mode functions IMF, by the intrinsic mode functions
Comprising signal sequence according to default length carry out window segmentation, the max-thresholds and minimum threshold of window are obtained, according to institute
State max-thresholds and minimum threshold is filtered；
Parallel two：Extract and filter out the baseline drift in electrocardiosignal, flesh is filtered out respectively using wavelet method and trapper
Electrical interference and Hz noise, above-mentioned three kinds filtered signals are added the reference signal as sef-adapting filter, it is and noisy
Electrocardiosignal carries out adaptive-filtering, generates output signal.
Specifically, in view of the frequency band and noise frequency band of electrocardiosignal have the phenomenon of aliasing, denoising is simply combined
Method can simply filter out totally to the noise beyond electrocardiosignal frequency range, and during noise denoising to aliasing, will certainly
The characteristic of each waveform is had influence on, so as to cause the distortion of signal.So also to be fully taken into account when to all kinds of Combination of Methods,
To keep electrocardiogram undistorted as far as possible during denoising.In addition, before all kinds of Combination of Methods are carried out, every kind of method is again
There is respective difficult point.Such as：With during Wavelet Denoising Method, it is necessary to consider the On The Choice of wavelet basis；With during threshold method denoising, it is necessary to
Consider the On The Choice of optimal threshold；With during morphology denoising, it is necessary to consider On The Choice of structural element etc..So
When selecting the combination of denoising scheme, respective advantage and disadvantage are taken into full account, are learnt from other's strong points to offset one's weaknesses.
The utility model realizes the purpose that aliasing noise interference removes by the parallel noise reduction of two-way：
Parallel one：Empirical mode decomposition (EMD) is especially suitable for handling non-linear and non-stationary signal, and it is maximum excellent
Gesture is that the basic function that need not be pre-defined to represent signal, the adaptively selected substrate of direct basis signal self-characteristic
Signal is analyzed, unlike wavelet method, it is necessary to define wavelet function, so as to face the On The Choice of wavelet basis, therefore very
Suitable for processing cardioelectric signals.But due to signal frequency band and the aliasing of noise frequency band, during denoising, letter can be caused
Number distortion, so, the utility model consider and Threshold denoising be combined.But soft, hard -threshold is all by will be greater than
The value of threshold value is arranged to given threshold value, and reaches the purpose of denoising less than the method for the value zero setting of threshold value, so as to increase mistake
The possibility of denoising by mistake, therefore the method that the utility model uses dual threshold.This method decomposites all from EMD first
Found in IMF containing noisy intrinsic mode functions IMF, and then the signal sequence that these IMF are included carries out " window " segmentation,
" window " length is set, the maximum, minimum in calculating " window " are worth to max-thresholds and minimum threshold, that is, obtain each " window
The dual threshold of mouth ", is filtered.
Parallel two：Mathematical morphology is the mathematical tool analyzed based on morphological structuring element image.It
Basic thought is to go to measure with the structural element with certain form and extract the correspondingly-shaped in image to reach to image point
Analysis and the purpose of identification.Electrocardiosignal is the One Dimension Periodic signal formed with PQRST ripples, so in selecting structure element, choosing
Selecting linear pattern can compare beneficial to analysis and processing.But this method is more sensitive to singular point, so as to which QRS wave shape can be caused
Distortion, so this patent considers to combine trapper, wavelet method and sef-adapting filter, and sef-adapting filter can be good at
Reflect real-time.This method is to extract baseline drift using morphologic method and filtered out first, secondly utilizes small echo
Method and trapper filter out myoelectricity interference and Hz noise, and then the signal of three kinds of filtering is added as sef-adapting filter
Reference signal, adaptive-filtering is carried out with noisy electrocardiosignal, is finally reached the effect of denoising.
