Description
Technical field
The present invention relates to a kind of heart sound Anti-control for chaos device based on heart sound chaotic characteristic.
Background technology
Organism is one to be had nonlinearity and typically exhibits the system of chaos phenomenon, and therefore human body is physiologically
Show stronger chaotic property.Chaos refers to the phenomenon occurring random motion in Deterministic Methods, it discloses non-linear side
Definitiveness in method and randomness, in order with unordered unification.The chaos phenomenon of research life entity contributes to preferably recognizing people
Non-linear and the irregular dynamics of body life process.
Heart is as one of mostly important and complicated nonlinear dynamic system of human body, since finding that heart is a chaos
Since system, people have carried out a large amount of cardiodynamics based on chaology research to it.Cardiechema signals is as diastole
Compound tone produced with complicated machinery motor process Myocardial, blood, cardiovascular and the valve etc. shunk, can well reflect
Heart various piece such as atrium, ventricle, cardiovascular and the substantial amounts of physiology of each valvular function state and pathological information and heart
The early stage pathology information of pathological changes.Substantial amounts of research thinks that healthy heart has a certain degree of intrinsic transmutability and is i.e. rendered as mixing
Ignorant state；Normally, there is the conclusion of significant difference in the chaotic characteristic of abnormal heart sound；Chaos controlling theory can control heart rate and lose
Often, the produced chaotic signal of control method fed back by direct ratio disturbance deactivates ARR heart so that heart turns
Beat for rule.These be heart early lesion computer-aided diagnosis and based on heart sound chaotic characteristic design heart sound chaos anti-
Controller provides theoretical basis.
But in the prior art, also lack ripe based on above-mentioned heart sound Anti-control for chaos device based on chaotic characteristic at present
Product, it is possible to accessory heart premature beat patient returns to heart beating normal condition as early as possible, not relaxing of reduction of patient.
Summary of the invention
The technical problem to be solved in the present invention is to propose a kind of heart sound Anti-control for chaos device based on heart sound chaotic characteristic, energy
Produce and meet the mechanical shock of heart sound Anti-control for chaos rule, external have rule by the chest of premature beat heart disease patient is carried out
Beaing of rule, with accessory heart, premature beat patient returns to heart beating normal condition as early as possible, not relaxing of reduction of patient.
For solving the problems referred to above, the technical scheme that the present invention proposes is a kind of heart sound Anti-control for chaos based on chaotic characteristic
Device, this cardiechema signals Anti-control for chaos device include heart sound transducer, memorizer, microprocessor, speech player and knocking by

With the real-time cardiechema signals collected, microprocessor is the core of whole circuit, is applicable to pathology heart sound chaos for generation anti-
Controlling the control law that the massage head with knocking masseur shakes, speech player is used for carrying out heart rate result report, heart sound
Sensor, memorizer, speech player are attached with microprocessor respectively with knocking masseur, constitute whole heart sound chaos
Revertive control device.
Further, above-mentioned knocking masseur uses electromagnetic shock mode, the intensity of knocking masseur vibrations and vibrations
Frequency by cardiechema signals Anti-control for chaos method control, by Real-time Collection to pathology cardiechema signals carry out chaos countercharge
System, obtains being suitable for the control law U of user self heart sound characteristic, this control law U acts on the massage head of electromagnetic shock formula
On so that the massage head of knocking masseur is operated by this control law U.
Further, the work process of above-mentioned cardiechema signals Anti-control for chaos method is: first gather a period of time real-time heart
Sound wave shape obtains control law U, beats outside patient chest then according to the rule of U controls knocking massage head；Beat
Continue for some time, then carry out the real-time heart sound collection of a period of time, then obtained new control rule by the cardiechema signals newly gathered
Rule U, then according to new U carries out knocking massage again, circulates so that heart sound collection massages two mistakes with beaing successively
Journey alternately, by the most repeatedly, makes premature beat heart sound progressively revert to normal cardiac sound, to slow down the symptom of patient.
As preferably, the above-mentioned time span continued for some time of beaing is 3-5 minute.
As preferably, described massage head uses flat structure.
Further, above-mentioned control law U produces by the following method:
1) gather the cardiechema signals of user and read the normal cardiac sound signal in memorizer；
2) above-mentioned collection and the two paths of signals read are processed through Nonlinear Tracking Differentiator respectively, respectively obtain two paths of signals
Follow the tracks of signal and follow the tracks of signal approximate differential signal；
3) obtained signal errors e by the tracking signal difference of two paths of signals, two-way follow the tracks of the approximate differential signal difference of signal
Obtain signal errors rate of change ec；
4) using the signal errors e obtained and signal errors rate of change ec as the input of Chaos and Fuzzy control module, thus
Obtain three controls parameter Ki, kp, kd of fuzzy control in real time, and obtained heart sound by the linear combination of these three control parameter
Anti-control for chaos control law U.
Compared with the technology treating premature beat heart disease in prior art, the heart sound Anti-control for chaos device of the present invention make use of
Chaotic property difference existing for chaotic characteristic that cardiechema signals is had and cardiechema signals normal, abnormal, uses chaotic feedback control
Method processed, and combine differential tracking thought, PID control method theory and fuzzy control theory so that abnormal (pathology) heart sound letter
Normal (healthy) cardiechema signals of tracking that number can be real-time, encourages pathology heart sound quickly to transfer regular beating to.And pass through
The cardiechema signals obtained after revertive control is carried out chaotic property analysis, and result shows that the chaotic property of this heart sound is remarkably reinforced.The heart
Sound Anti-control for chaos device can produce the mechanical shock meeting heart sound Anti-control for chaos rule, by premature beat heart disease patient's
Chest carries out external regular beat, and can return to heart beating normal condition as early as possible with accessory heart premature beat patient, effectively alleviate
Patient's does not relaxes.
