Description

Detect article, the method and system of physiological function and posture state
Detect article, the method and system technical field of physiological function and posture state
The present invention relates to can be applied to the detecting physiological function in the fields such as physical training, medical treatment, body-building, health care, amusement and industry security and article, the method and system of posture state.The posture state of user is more particularly to obtained by the physiological signal for sensing non-posture, situation is changed available for detecting user's work safety, health status, body-building effect and posture state.Background technology
With standard of living and health care significant progress, average human life gradually extends, and proportion of aged population continues to increase.In face of the society of aging, with showing the problem of various social welfares, medical medicine technology and social safety system, increasing People can not be obtained by household and family and properly sufficiently looked after.This sunset is foretold, and due to diet and the change of habits and customs, the population ratio with chronic diseases such as hypertension, diabetes, gout, high fat of blood and heart diseases also rapidly rises.These, which are had a large population, needs instant system of monitoring physiological function, to detect the physiological function of correlation whenever and wherever possible, to prevent unexpected generation.
For example：Electrocardiogram is observation heart most convenient and conventional instrument, is not only measured several minutes in the consulting room of doctor, it is to want non-volatile recording also to have many occasions, the Hol ter electrocardiograms of such as 24 hours.Preferable electrocardiogram, is to have comfortable electrode, can make continuous record for a long time on the premise of daily life is not disturbed.But paster style physiological electrode usual at present, if it is 4 blunt uncomfortable to be attached to for a long time on skin, only it is useful in professional medical occasion.Therefore, electrocardiosignal is obtained with continuous for a long time using non-SMD electrode, is always important research topic.One of existing solution, it is that electrode and signal transmssion line are made of textile, it is fixed on clothing or chair, bed, user can so be allowed in the case of more comfortable, obtain electrocardiogram, many electric wires will not be led as conventional ECG machine again, user's action is allowed and is restricted.However, to signal transmssion line is fixed on clothing, allowing user comfortable again, signal transmssion line should not be oversize too complicated too much；But to allow user's various postures in daily life work and rest to obtain electrocardiogram, on clothing it must set electrode and signal transmssion line more.This awkward predicament is solved, it is to allow multiple electrodes to share signal transmssion line to have a method, and the other physiological sensors of identical reason are also such situation.
On the other hand, electrocardiogram is not unalterable, otherwise its posture to body is very sensitive.It is known when people is changed to standing by lying on the back, heart rate can be temporarily increased（With reference to United States Patent (USP) 5,354,317), when body gesture changes, electrocardiographic wave can change therewith immediately（With reference to United States Patent (USP) 5,865,760).The waveform for the electrocardiogram that the known electrode by human body different parts is obtained is different, because electrocardiogram is by the mechanical periodicity of the polarization and depolarising of myocardial cell membrane, on " vector " for being projected in the formation of any two electrodes.Therefore, it is theoretically feasible to judge human posture by electrocardiographic wave.In the useful multiple electrodes measuring heart-beat of United States Patent (USP) 7502643, but without thus ECG (electrocardiograms simultaneously）Waveform surveys user's posture state.The change of posture, be also a critically important information, if for example someone sleep when change posture it is too frequent, may represent this person sleep it is poor quality, if if someone the change posture in sleep is greatly reduced suddenly, may represent this person has thrombus obstruction four limbs or the cerebrovascular.United States Patent (USP) 6384729 and 5508540, is the contraction situation that abdominal muscle is surveyed using inductor.United States Patent (USP) 4988981 is then the posture that hand or body are measured with inductor, and United States Patent (USP) 5914701 surveys posture also with capacitance variations between two electrodes.Useful two in US6930608 United States Patent (USP)s Sensor senses identical physiological status, but can not also sense another posture state unrelated with original sensor simultaneously.Japan has a patent JP2009-18158A to be also to read the physiological signal of human body while reading the postural change of human body, but it is the sensor for being attached to detecting posture using physiological sensor, such as accelerometer, gyroscope is with inclinator（Ti l t Sensor), this is not pressure or pulling force sensor, while can not filter noise yet.Previous PCT/CN2005/001520 electronic switches, which are just mentioned, to be connected switch with physiological sensor to detect physiological signal, but is not mentioned simultaneously using switch and the signal intensity produced by physiological sensor, can measure the postural change of human body.

Further to illustrate the technological means taken and effect of the invention to reach predetermined goal of the invention, below in conjunction with accompanying drawing and preferred embodiment, to according to electrocardiogram proposed by the present invention monitoring and human posture's determination methods, device and system its embodiment, structure, feature and its effect, describing in detail as after.
For the present invention foregoing and other technology contents, feature and effect, can be clearly appeared from the detailed description of the preferred embodiment of following cooperation referenced in schematic.Pass through the explanation of embodiment, one is obtained when the technological means and effect that predetermined purpose taken can be reached to the present invention more deeply and specific understanding, but institute's accompanying drawings are only to provide reference and purposes of discussion, not for being any limitation as to the present invention.
The present invention sets the switch of physiological sensor connection at least one, the pulling force of at least one group non-posture in the article contacted with body（S tra in gague) or pressure sensor, the physiological sensor of this at least one set of non-posture either alternatively or simultaneously senses the physiological signal of former inductor, while at by data signal After reason and analysis, the posture of user is also can determine whether, therefore in addition to the physiological function of itself, the posture state of user at that time can also be learnt.
Most times will put on clothing, be sitting on chair or lie on a bed in people's daily life, therefore sensor is set on cap, scarf, shoes, clothing, seat, sheet or pillow, the present invention is simultaneously combined pressure or pulling force sensor with physiological sensor, can not only noise be reduced while going back the article of the next contact of automatically starting, and the article of previous contact can be closed with power saving automatically, continuous record for a long time can be made, user need not be limited by sensor and electric wire.Further, as the physiological signal obtained by the sensor on diverse location, or the different physiological signals obtained by same position, and these signals can be obtained in identical or different article, growth time can be integrated and continuous physiological function and postural change figure, had very great help for the healthy of user and safety.This current technology by IEEE, EMBC 2009 can examination ＆ verification, it is will be delivered in September, entitled " Sleeping ECG and body pos i tion moni toring sys tem,.
General framework of the invention is referred to as shown in Fig. 1.The article of physiological sensor will be laid, such as clothing, socks, sheet, pillow or seat, directly or indirectly contacted with people（For example between physiological sensor and skin, across underwear）.Electric capacity physiological sensor regards application scenario and configured on location, and switch of arranging in pairs or groups, for example：Key switch or crack switch.The technology of this switch, pressure or pulling force sensor is as shown in PCT/CN2005/001520 electronic switches；In addition, PCT/CN2008/001571 can form the cloth of electronic building brick, PCT/CN2008/001570 has the cloth or PCT/CN2009/000118 sensing device furthers of separation induction zone, these are switch entirely, pulling force or pressure sensor, if connecting result such as Fig. 1 of non-posture sensor a, b, c, d is switch, also available pressure device replaces and produced identical effect for position that pressure or pulling force sensor can be placed, that is at least individual physiological sensor connection at least one is switched, pulling force, pressure sensor or pressure device connect or can contact with each other to make physiological signal to be received physiological signal by processor during external force.This physiological signal can be used to judge the postural change of user simultaneously.And certain critical value can be set just start connected physiological sensor or close the previous article detected, therefore use and be positioned in tactile body article as switch, combined simultaneously with non-gesture sensor, such as ECG electrode, thermistor, make electrode, brain wave electrode, electromyogram, breathing soaked with sweat（Resistance spirometer impedance phe draw graphy), heartbeat, humidity body fat, infrared temperature sensing device, blood pressure sensor, pulse sensor, resistance-type breathing sensor, blood oxygen sensor, blood glucose sensor etc., can assist to judge that posture is more accurate.Because each switch can set the critical value of an external force, when external force is more than critical value, physiological signal just can entering signal processor.Using the purpose of switch, it is to choose suitable position according to human posture to capture physiological signal, the effectively introduced noise of isolation false touch can close the power supply of previous article again, and being capable of power and energy saving.
Physiological signal is connected to the circuit in signal processor 22 by switch, pressure or the pulling force sensor of first, second grade sensor and its connection.Physiological signal amplifies analog signal first via amplifier, then removes high frequency and low-frequency noise and Analog-digital Converter through analog bandpass filter, then the program stored in controller is analyzed signal.Microcontroller calculates the feature of signal, and according to the feature information of the position in the database prestored, both compare, you can judge the posture of user.Signal processor 22 itself can also have display function and by sounding or the luminous function to warn, and can also have the communicator of the wirelessly or non-wirelessly function of two-phase flow in signal processor 22 in addition.Therefore physiology and postural cue also can deliver to personal information device by the communicator in signal processor 22（PDA or PC）, to receive, record and show physiology and postural cue.In addition, signal processor 22 Interior signal pre-treatment（Signal is amplified, filters and goes P tiltedly not number conversions）, analysis（Extract the feature of signal) or database purchase, also it can handle and store in personal information device.For same user, personal information device can receive the signal that one or more signal processors 22 are spread out of, one group of sensor and switch, pulling force or pressure sensor and signal processor 22 are for example respectively loaded onto on the B＆C of user, growth time is integrated again and continuous individual physiological and posture information, and user need not be limited by the SMD sensor and electric wire of conventional method, it is possible to send alert news in good time according to default judgment criterion（For example car steering is not fastened the safety belt or dozed off）.
Fitted between contact for sensor to be increased with people, a material can be added between sensor and cloth or leather to increase thickness, for example：Elastic material, such as sponge, rubber, silica gel, spring.And capacitance sensor, such as temperature-sensitive sticker, humidity sensor, there can be different heat transfer or transmission coupling because material is different or thickness is different again.Meanwhile, in order to prevent false touch or the too many signal of simultaneous transmission, also can Jia one between sensor and cloth or leather switch, pressure or pulling force sensor, the startup that this switch, pressure or pulling force sensor can be detected according to pressure or pulling force come control signal.And the sensor for disconnecting switch can reach effect of power saving without power drain.
Switch, pressure or pulling force between physiological signal and people and sensor is relevant, does not have signal when being not in contact between people and sensor；When the contact between sensor and people is bad, signal is not also good.The present invention, which is utilized, builds switch or crack switch and sensor serial or parallel connection, only when pressure is enough, physiological signal can be just conducted to circuit, multiple sensors can be so allowed to share a transmission lines, avoid unnecessary physiological signal to disturb the desired signal of physical record, so can both reduce the quantity and length of transmission line, and user can have been made more comfortable again, and when user changes posture, also still there is sensor to be pressurized to obtain physiological signal.Connected for example, setting a key switch at back with sensor, when user lies supine upon bed, back is pressed onto mattress, and the physiological signal that sensor is obtained can be just conducted to circuit；And for example, being set at knee cap, crack switch is in parallel with sensor, and when user goes down on one's knees, crack switch is pulled open by pulling force at this, and this pulling force can make trousers press close to knee joint, and the sensor at this can obtain physiological signal.When user stretches leg, trousers, which lose pulling force, would not press close to knee joint, and sensor is that can not obtain physiological signal.In Fig. 1, when being connected between processor and physiological sensor, pressure or pulling force sensor using transmission line, it is to have a reference area to be connected with processor beside it when transmission line does not insulate, for surveying transmission line, whether with reference area to produce leaky such as cloth overly wet, or transmission line and reference area touch generation short circuit condition.When there is the circuit for the treatment of, such as heating, cooling, TENS (transcutaneous electrical stimulations）Or electrode etc. must also have side during nuditing wire also to have reference area to survey electric leakage situation.As long as or can all have reference area by the wire on cloth on circuit to detect leakage condition, reference area also can be used as electrode, heater wire or antenna to use in itself
The preferred embodiment of the mat woven of fine bamboo strips one
Refer to shown in Fig. 2 and Fig. 3, be that the first preferred embodiment of the present invention is applied to the configuration diagram of nightwear and the electrode and key switching structure schematic diagram of the first preferred embodiment.The configuration diagram applied to nightwear of first preferred embodiment of the invention, it is used for recording electrocardiogram and judges human posture, include the electrode 101,102,103,104,105,106,107,108 with Switch, signal processor 22, and personal digital assistant or PC 12.The structure of switch electrode is as shown in figure 3, the electrode 15 contacted with body is arranged on the ad-hoc location of clothing 1, and there is a key switch 10 each top of electrode 15, and electrode 15 is connected with key switch 10.When key switch 10 is depressed, key switch 10 is into conducting state, and electrocardiosignal is connected to signal processor 22, and electrocardiosignal amplification, the filtering of simulation are removed into noise, analog-to-digital conversion（Analog- to-digi tal convert ion) ^, then Ecg wave form is analyzed with program.As " ^！Switch 10 is built when not being depressed, key switch 10 is into open-circuit condition, and electrocardiosignal cannot connect in signal processor 22.Thus, when user changes sleeping position, just there are different key switches 10 to be depressed, that is, the electrocardiosignal for having the electrode of different parts to obtain is conducted to instrument amplifier, ecg wave form is also just different therewith, so can judge human posture by ecg wave form.Shown in Fig. 3 is key switch or multi-step button switch to produce different critical values, or is replaced with pulling force, pressure sensor and and can connect or connect with physiological sensor, while pulling force pressure sensor can be digital or analog sensor.This switch, pressure or pulling force sensor may belong to two different bed of cloths, and this technology is described in previous PCT/CN2008/001570 or PCT/CN2008/001571.
It is as shown in Figure 7a the electrocardiogram under four kinds of sleeping positions of user, it may be seen that QRS (i.e. Q ripples, R ripples and S ripples when user sleeps）Waveform is maximum, ECG when just sleeping then secondly, the waveform that left side is slept sometimes to just sleeping when it is similar, the ECG waveform that right side is slept is minimum, still by the ECG electrode reversal connection on left side and right side, cause the waveform phase of output reversely, as shown in Figure 7b.This can just be very easy to learn user posture why, on the one hand obtain the ECG signal of user, at the same by ECG signal learn user posture why, therefore can cylinder list conclusion result as shown in Figure 7 c.And Fig. 7 d can then be learnt the sleeping position of user by ECG waveform.Same principle, we can be obtained outside physiology information using the result of different physiological sensors and pressure or pulling force sensor output signal, it should also be appreciated that the postural change of user.
Because clothing has electrode, when user sleeps, different sleeping positions is for example just slept, left side is slept, sleep be pressed onto electrode difference, causes the waveform difference of electrocardiogram, its principle is as stated in the Background Art.If just sleeping and the electrode of chest is also switched on if both hands embrace chest, but its from only just sleep or lie prone sleep gained electrocardiographic wave it is again different, therefore can be changed using the waveform of electrocardiogram, carry out posture and its change of detecting sleep, while generation activity diagram（Act igraph accordingly, can learn the depth state of user's sleep；Also heart rate variability can be calculated by ECG signal（Hear t Rate Var iabi l i ty, HRV>Or breathing, so as to estimate the depth state of its sleep.In general, the flexible of thoracic cavity muscle can cause the drift of electrocardiogram, and for sleeping just user, this drift is i.e. from breathing.Thus, capture the low frequency part (being less than 0. 3 Hz) of ECG signal, you can obtain breath signal.If user's sleep is shallow, body contact electrode, which makes to contact between body and electrode, constantly to be changed, and electrocardiographic wave also just changes therewith, and so then signal noise can become big, therefore from the noise change procedure of signal, estimate the depth state of its sleep or whether clear realize.Similarly with other sensors in the case where human body mind understands situation, noise can also increase, if user is in quiet or sleep, noise is also just reduced.Therefore the depth state of its sleep from the noise change procedure of signal, can be estimated or whether clear realized.
It is the electrocardiogram obtained by the various sleeping positions of the first preferred embodiment of the invention as shown in Fig. 6 a to Fig. 6 m.The not outer back of the body of common people's sleeping position is lain on the back, right side is crouched, lie on the left side, four kinds of prostrate, in order to obtain electrocardiogram in four kinds of sleeping positions, as shown in Fig. 2 the present invention is respectively mounted with two electrodes in the surrounding of nightwear.Electrode 101-108 includes bubble silk floss 14, and key switch 10 also has stereochemical structure, can so increase the chance and reliability contacted between people and electrode 101-108.
Other key switch 10 has stereochemical structure and button originally also has electrode structure i.e. pressure or pulling force sensor while being also electrode, such as：Key switch or crack switch inherently electrode.This technology such as PCT/CN2005/00152G electronic switches；PCT/CN2008/001571 can shape ^ electronic building bricks cloth or PCT PCT/CN2008/001570 have separation induction zone cloth, therefore switch is also simultaneously in itself electrode, also it can use and be positioned in article as physiological sensor simultaneously, such as sensing electrocardiogram, Electromyogram, breathing（Resistance spirometer impedance pheumography), heartbeat, humidity, electroencephalogram, body fat etc..It can also be pressure in addition or pulling force sensor is connected to physiological sensor, and certain critical value can be set just to start physiological sensor or close the previous article detected.
On the other hand, two conductive fabric one electric capacity of formation, under outside pressure or pulling force, its capacitance also and then changes, principle is to provide a fixed frequency from external system and detect the electric capacity between two electrodes, and the presentation of its pressure or tension variations is showed with voltage or frequency.So, itself it is also a pressure sensor or pulling force sensor, the posture one of such as people has variation, its capacitance also and then changes, for example under a certain degree of pressure, physiological signal is just received, and otherwise signal is to cancel, for example, set certain critical value and just start physiological sensor or close the previous article detected, therefore two conductive fabric one electric capacity of formation, as a switch, while conductive fabric also serves as electrode, therefore also work as ^ simultaneously：Physiological sensor is used.
Same mode, uses an oscillator（Osci l lator), the oscillator of especially one unstable state measures the capacitance variations between cloth electrode and human body, and capacitance variations are showed with resonant frequency, also there is identical effect, that is to say, that conductive fabric be in itself a pressure sensor also serve as be one switch.Identical, conductive fabric is also electrode in itself, thus also as physiological sensor using come measure electrocardiogram, electromyogram, 4 inhale（Resistance spirometer impedance pheumography>, heart iMillionth, humidity, brain electricity, body fat etc..Certainly two conduction cloths are used, the result obtained by the oscillator of cloth and a unstable state is also the same, and one of them is also treated as electrode to measure electrocardiogram, breathing, electromyogram, E.E.G or offer TENS, electric shock etc. treat use.
The purpose of distribution of electrodes position is chosen, is the solid angles for having acquirement different（Relative to heart）, therefore heart itself electrical activity be projected in electrode 101-108 vector result it is also different, thus i.e. can determine whether sleeping position.There is mother-in-law in first three sleeping position, the hand of user is possible to be pressed onto front or clasps toy or bedding, and start the electrode 101,102 of front, therefore first three sleeping position is each sub-divided into four kinds of situations again, it is to more detailed postural change, then middle before and after user to add an electrode again, just have more detailed postural change result and produce, i.e. more sensor distributions, resulting posture resolution ratio is just higher.With regard to prostrate sleeping position, the hand of user is hardly possible to be translated into behind to start electrode 105,106 backward, therefore only considers the situation that electrode 101 and 102 starts.Various sleeping positions and the electrode of unlatching 10 foretell 108, refer to shown in table 1, have displayed the electrode that the various sleeping positions of the preferred embodiment of the mat woven of fine bamboo strips one of the present invention are started.

Prostrate+- refers to table 1, it can be seen that have many situations be two electricity-parallel connections again；F arrives ecg amplifier input, and its equivalent circuit is also different from traditional electrocardiograph（As shown in Figure 4）.Because the internal resistance of human body surface different parts may have very big difference, the skin of such as front is very thin again near apart from heart, its internal resistance thus very little, otherwise the internal resistance of back is just much larger, and this electrode 101,102,105,106 at two is connected in parallel, it is likely that without enough effects.Therefore, in a specific embodiment of the invention, between the front end of signal processor 22 and a certain electrode, an external resistor 111 of connecting, to obtain preferable shunt electrodes effect.Similarly, the impedance operator of viewing human and the frequency of signal（There are different frequencies such as ' electromyogram, capacity of blood vessel, breathing, humidity, blood oxygen, body temperature, body fat）, optionally serial or parallel connection resistance, inductively or capacitively.
Refer to shown in Fig. 5, be the definition of typical Lead I electrocardiograms each point, with microcontroller or remote control storage program analyze ecg wave form algorithm it is as follows.For the electrocardiosignal of entering signal processor 22, first with existing known Digital Signal Processing（With reference to Biomedical Digi tal Signal Process, by Wi l l is J. Tompkins, 1993), handled.As shown in Fig. 8, the first embodiment of the present invention is as follows to the processing method of electrocardiosignal：Electrocardiosignal is quantified and stored first with the analog-digital converter in signal processor 22, after noise is filtered out with bandpass filter（Quadravalence Bezier bandpass filter, 0. 06-40 Hz), the R points in electrocardiosignal are then found out by program（Take amplitude maximum point）And polarity, P, Q, S, T each points are then found out again.Due to 12 not usual helical pitch normal places of electrode position, therefore waveform is different from reference waveform, as shown in figure 5, still those skilled in the art still can find out foregoing each point with the feature of the points of R, P, Q, S, T in existing known technology.Then, then R, S, the amplitude of Τ each points are found out（It is defined as VR, VS, VT).Electrocardiogram under some sleeping positions, can (but R peaks necessarily have without P, S or T ripple）, or its direction and standard lead I are on the contrary, this is all the feature used in interpretation sleeping position.The present invention is captured eight features, is met its judgment criterion and be calculated as 1, be not inconsistent as 0 by the analysis to various sleeping positions, as follows：
1. T wave-amplitudes are more than kl times of R wave-amplitudes：This abnormal big T ripple, only occurs in prostrate, mark is VT>Kl*VR, wherein, kl between（0. 6 to 1. 0) between, preferably 0. 8;
2. there are P ripples:No matter direction is positive or negative, mark is P;
3. R ripple polarity：Forward direction is 1, and mark is+R;
4. R wave-amplitudes are more than 2 times of S ripples：There are significant R ripples to be then calculated as 1, mark is VR>K2*VS, wherein, k2 between（1. 8 to 2. 2) between, preferably 2;
5. forward direction S ripples：There is forward direction and be then calculated as 1, mark is+S;
6. negative sense S ripples：There is negative sense and be then calculated as 1, mark is-S;
7. positive T wave：There is forward direction and be then calculated as 1, mark is+T;
8. T wave-amplitudes are more than k2 times of R wave-amplitudes：Mark is VT>K3*VR, wherein, k3 between（0. 35 to 0. 65) between, preferably 0. 5;
Electrocardiosignal under typical various sleeping positions is referred to shown in Fig. 6.
Refer to shown in table 2, the feature of various sleeping positions is concluded.If there is this feature, mark is 1.The present invention is the number of a byte according to precedence eight features volumes, and is represented with two 16 binary digits.
Fig. 7 a are then Fig. 1 ECG results, and each of which has a pressure sensor to connect and be output to processor jointly to electric shock, and Q, R, S amplitude that our visible ^ lie are maximum, just lying and left side is lain When（), R, S amplitude it is placed in the middle, P ripples are not obvious when left side is lain, and Q, R, S amplitude are minimum when right side is lain, but P ripples are obvious.
Fig. 7 b are then that, by the contact reversal connection of the electrode of left and right sides and processor to produce anti-phase electrocardiogram (inverse phase), therefore can distinguish left side and the ECG Change just lain, i.e., we are reverse by the electrocardiogram phase on left side and right side.Therefore Fig. 7 c analysis logic can be obtained, when amplitude is big and forward direction is lain to lie prone, amplitude is lain greatly and on the left of being reversed, and amplitude is small and positive just to lie, and amplitude is small and is reversely then lain for right side.Therefore thus analysis method can obtain the posture state of user as shown in figure 7d.
Table 2
In practical application, the electrocardiosignal more or less difference of each user, it is adaptable to certain Yue judgment criterion, such as different users, kl-k3 needs to select different numerical value just to obtain more preferable effect.Therefore, one or three axle accelerometers, gyroscope, inclinator or magnetometer are housed on the circuit board further in signal processor 22 of the present invention, the inclination angle on accelerometer or other posture sensors and ground can be learnt by gravity when static.When user opens the system for the first time, system may require that user fixes signal processor 22 piggyback with hand, to determine the sleeping position of user, then converts various sleeping positions and allows network analysis.Similarly, the present invention can also detect posture with the sensor of other species, for example, gyroscope, video signal instrument（Video camera) etc..The parameter setting of the system has self-learning function, when user makes various sleeping positions, system can carry out the feature extraction of R, P, Q, S, T point to the waveform of the electrocardiosignal under each posture and repeatedly calculate kl-k3, finally take average either pre-set parameter of weighted value when being used as actual use person of result of calculation, to adjust the judgment criterion that the user is optimal, flow chart is as shown in Figure 8.User is also allowed in addition in the case of no accelerometer or other posture sensors, from the various sleeping positions of line translation, so as to the ECG signal of each sleeping position of network analysis.In the future in real use, because nightwear is loose in itself, thus accelerometer can not possibly abut against with to provide sleeping position to system, therefore the system of the present invention also provides another way, that is, points out user when system self study carries out parameter setting, it is necessary to which which kind of sleeping position user provides, so that system determines parameter kl- k3 numerical value, in addition, adding some electrode sensors in different places, then the differentiation of posture is more various.The critical value of different switches, pulling force or pressure sensor is especially can adjust in response to different statures and body weight, then effect is good.

Refer to shown in Fig. 9 a, be electrode position and connection diagram that the second preferred embodiment of the invention is applied to bicycle knight clothing and trousers, circuit part is same as Example 1, wherein No. 1 to No. 5 electrode is all connected with switch or pressure sensor.
Fig. 9 b show switch, pressure or the pulling force schematic diagram of hand set hand position.I.e. right-hand man has the conductive fabric of set hand position, it is flexible material shield to cover hand cloth, and have the switch of connection one, pressure or pulling force sensor, then this person when walking or sit back and wait posture right-hand man ECG signal can pass to processor formation 2 pole electrocardiograms, if thering is pressure or switch to be in contact with the conductive material on underpants in hip or clothing pendulum plus thering is conductive fabric directly to contact in clothing pendulum and close on hip position, three pole electrocardiograms are then produced, and are the helical pitch electrocardiograms of the mat woven of fine bamboo strips two.
If the cotta clothes in summer, then the design for covering hand is changed to flexible material such as elastic band or is located at cotta cuff to replace such as Fig. 9 c.So that people's cuff of right-hand man in action is still contacted with skin, while there is conduction cloth on cuff.To survey at cuff and the laminating degree of arm then has pressure or pulling force sensor（Such as Fig. 9 d) it is connected with conduction cloth.Wherein the first conduction region has an accessory such as button structure thereon, and the second conduction region then has a flexible clasp line (such as Fig. 9 d element numbers 3), can be used to clasp button.Second conduction region can be divided into 3 sections of conduction regions, when pulling force difference touches different conduction regions, then also can be different for position and number.The pulling force of first and second conduction region can be then measured using electric capacity or resistance, while first and second conduction region can also work as electrode to sense ECG or EMG (electromyograms）, or connect other non-posture physiological sensors to survey physiological signal.This pulling force sensor can be also designed at the other places such as bottoms of jacket of dress ornament or the opening of trousers, or clothes and trousers, trousers and socks connection.Breathing can be also surveyed with this structure, is made soaked with sweat, body fat, E.E.G or offer TENS.Piggyback can also there is pressure sensor to connect following electrode cloth in addition, and have a signal processor on left or right shoulder, then when this person puts signal processor piggyback, while starting the detecting of electrocardiogram.The thing that we can also put shoulder pad on left or right shoulder enables pressure sensor to turn on and electrode is passed ECG signal, electrode cloth is set to be made electrode cloth be difficult separately to detect for a long time with human body by the thing such as control box of shoulder pad simultaneously, pressure sensor can also be replaced with pulling force or switch sensor, surveyed with pressure or pulling force sensor electrode cloth and body pressure or pulling force why, can just allow signal stabilization.
Refer to shown in Figure 10 a- Figure 10 d, No. 1 electrode of front may be touched less than body, but back electrode（No. 2 No. 3 parallel connections, ecg amplifier positive and negative terminal is connect with No. 4 respectively）Electrocardiogram can be measured, Figure 10 a are referred to.When suspending and standing on road, knight does not bend over, and No. 1 electrode of front encounters body, now No. 2 No. 3 electrode parallel connections, and 1 is in parallel with No. 4 electrodes, and ecg amplifier positive and negative terminal is connect respectively, electrocardiogram is obtained（Figure 10 b), compared with Figure 10 a, the significant increase in R peaks, but without P ripples is thus i.e. distinguishable to bend over or uprightly.Similarly, when knight sits on cushion and upper body is vertical, by No. 1 of front and No. 5 electrodes of buttocks, electrocardiogram can be measured, Figure 10 c are referred to;When knight stands, police portion is not pressed onto No. 5 electrodes, and the electrocardiogram of stern is to vanish from sight, and expression is not sitting on bicycle.Judge that the criterion of posture is listed in table 3.
Electrode is also mountable on trousers and socks, wherein No. 6 are located at No. 7 electrodes near the knee joint of trousers, and each crack switch or pulling force sensor in parallel；No. 8 are located on socks with No. 9 electrodes, and each one key switch of series connection；No. 9 electrodes are connected with No. 7 electrodes, and No. 6 are connected with No. 8 electrodes.Straight and pin is beaten when knee joint to touch on the ground, compressing No. 8 and No. 9 electrodes, and the electrocardiosignal that No. 6 or No. 7 electrodes do not suffer oppression therefore can measured by No. 8 and No. 9 electrodes（Shown in Figure 10 d）, No. 6 No. 7 electrode conductions can be made when left knee or right knee joint bending when walking and obtained with the socks electrode of another pin Different electrocardiograms.By above-mentioned, we may determine that user is to walk, plant oneself or going down on one's knees.Table 3
Signal processor captures electrocardiosignal and judged after posture, i.e., this information is sent into personal information device, and personal information device can give user's suggestion or alert news according to the default scope of user.For example when measure HR Heart Rate it is excessive when, it may be possible to the physical load of cycling is overweight, can now send suggestion, reminds user to slow down and rides speed.All unchanged with acceleration when measuring long-time posture, it may be possible to fall down and remain unconscious, now personal information device can be automatically by various wireless telecommunications pipeline (mobile phone or Wi-Fis）, send individual or mechanism of the alert news to distal end, plea for aid.
The preferred embodiment of the mat woven of fine bamboo strips three
Refer to shown in Figure 11, be that the electrode of the 3rd preferred embodiment of the invention is placed in the schematic diagram of bedding.The electrode 12a- 12e that the embodiment of the present invention three is contacted with body are arranged on the ad-hoc location of bed, set key switch, pressure sensor simultaneously, circuit part is similar with Fig. 1, and simply key switch or pressure sensor are located on clothes and key switch or pressure sensor are also electrode in itself.Electrode 12a 12b, it is connected with 12d, electrode 12c is connected with 12e, respectively as the positive negative input of amplifying circuit.Input amplifier closes (capaci t ive coupl ing) using condenser type, to obtain the electrocardiosignal of human body through key switch or pressure sensor.When user changes sitting posture or prone position, body contact electrode position is different therewith, and ecg wave form is also just different therewith, ' so human posture can be judged by ecg wave form.This is to set processor in bed.
For example：There is electrode on pillow and sheet, then do not sleep the different sleeping positions of person and be pressed in pillow and also change therewith with the electrode position on sheet, while electrocardiogram is also different.Refer to shown in Figure 12 a- Figure 12 c.（Figure 12 a are not propped up for the neck that just crouches by the leg of bed two；Figure 12 b prop up for the neck that just crouches by the leg of bed two；Figure 12 c keep flat for the neck that just crouches by the leg of bed two）.Judge that the criterion of posture is listed in table 4

4th preferred embodiment
Refer to shown in Figure 13, be electrode position, connection and Organization Chart that the 4th preferred embodiment of the invention is applied to automobile driver seat.
Each electrode is connected with pressure sensor.There are two electrodes present pre-ferred embodiments four, front（211 and 212), wherein electrode 212 is oppressed in the Shi Douhui that just sits and lean forward and connected by safety belt, but then no in "Left"-deviationist, as long as electrode 211 is then to fasten the safety belt to connect.Various sitting postures（Just sit, lean forward, right side is inclined, left side is inclined, without safety belt）The electrode of lower startup, and two electrocardiosignal amplifications Device whether there is acquisition electrocardiosignal（To whether there is the judgement of R peaks）Situation as shown in table 5, the electrocardiographic wave of acquisition is as shown in figure 14.The electrode I to 216 of 1 to No. 6 electrode sequentially for 5 listed by table 5.Judge that the criterion of posture is listed in table 5.
Table 5
As shown in table 5 and Figure 13, the sitting posture driven can be judged easily.There is safety belt left-leaning with just sitting two kinds of sitting postures without safety belt, it is necessary to be judged with waveform except indivedual, as long as seeing whether ecg amplifier A, B have output electrocardiogram to coordinate R peaks to table look-up again again and can determine that for other sitting postures.Differentiating "Left"-deviationist has safety belt very easy without two kinds of sitting postures of safety belt with just sitting, and the former has huge T ripples almost typically high with R peaks, and the latter's T ripple very littles, by judging VT>K6*VR is to understand.Similarly, band has been differentiated to lean forward and have band Right deviation, also can be by T ripples, the former has huge T ripples and the latter's T ripples are blunt small, by judging VT>K6*VR is to understand.Wherein, k6 is between 0. 7 to 0. 9, and preferably 0. 8.
Because driving can encounter the situations such as emergency brake, pit-hole unavoidably, now because human body is acutely rocked, electrocardiosignal meeting serious distortion can exclude these unusual conditions to interpretation, the present invention is difficult to using accelerometer.After multiple actual test, conclusion is concluded to obtain：When transient acceleration is more than 9. 8 meter per seconds2(acceleration of gravity on One Earth One Family surface, when g), electrocardiosignal can serious distortion to being difficult to interpretation.Therefore the method for the present invention, accelerometer signal can be captured simultaneously, when acceleration is more than 9. 8 meter per seconds2When can stop analysis electrocardiogram so as not to erroneous judgement.
