Specific embodiments of the present invention will be further explained with reference to the accompanying drawing.It should be noted that for The explanation of these embodiments is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, disclosed below The each embodiment of the present invention involved in technical characteristic can be combined with each other as long as they do not conflict with each other.

A kind of lie detecting method includes the following steps as shown in Fig. 1：

Step 1, testee wear Intelligent bracelet, and start bracelet, and wherein bracelet is used to detect the biological telecommunications of testee Number.

In the prior art, the bioelectrical signals of testee are generally checked using plurality of devices, for example detect blood with sphygmomanometer It is cumbersome to wear use using the bioelectrical signals that various equipment detect testee respectively in this way, but also is only used for short for pressure etc. Time detects a lie.

In an embodiment of the present invention, bracelet specifically includes bracelet ontology, control module, communication module and detection module, Control module, communication module are arranged in bracelet ontology, and detection module is connect with control module, and detection module includes skin electro-detection Device, blood oxygen detection device, ECG detection device, apparatus for testing body temperature and body move acceleration detecting, and control module passes through Communication module is connect with terminal device.

Skin electro-detection module includes skin electric transducer, and skin electric transducer includes two skin electric transducer probes；Blood oxygen detection Module includes blood oxygen transducer, and blood oxygen transducer includes blood oxygen transducer probe；It two electrocardioelectrodes of ECG detecting module and sets Set the electrocardio driving on bracelet；Temperature check module includes body temperature transducer；The dynamic acceleration detection module of body, which includes that body is dynamic, to be added Velocity sensor.

Above-mentioned bracelet is worn in this way in testee's left hand wrist：Two skin electric transducer probes are worn on testee's On left index finger and the third finger；Blood oxygen transducer probe is worn on the left hand middle finger or thumb of testee；Two electrocardio electricity Pole can be divided into LA electrode and RA electrode, and wherein LA electrode is worn on left side chest nipple and the clavicle middle position of user, RA Electrode is worn on right side chest nipple and the clavicle middle position of user.

It is easy to operate using simple using the bioelectrical signals of bracelet acquisition testee, and testee can wear for a long time It wears to carry out judgement of detecting a lie for a long time.

Step 2 selects material of detecting a lie from multimedia stimulation water conservancy diversion, and shows material of detecting a lie to testee.

Wherein multimedia stimulation water conservancy diversion includes multimedia stimulus file, hearing response problem and/or evidentiary material, wherein more Media stimulus file can be file, be also possible to the material that picture or video etc. can play on multimedia equipment.

Step 3, bracelet receive the bioelectrical signals of fluctuation of the testee by material stimulation generation of detecting a lie and generate physiology Data are sent to terminal.

Due to including multimedia stimulus file, hearing response problem and evidentiary material these materials in material of detecting a lie, accordingly Material can to testee generate stimulation, and then make testee generate fluctuation bioelectrical signals.

Wherein, physiological data includes that skin resistance data, blood oxygen saturation data, electrocardiogram (ECG) data, temperature data and body are dynamic Data.

Step 4, terminal analysis physiological data and generation are detected a lie as a result, Fig. 3 is terminal analysis physiological data and generation is detected a lie As a result flow chart specifically includes following steps as shown in Fig. 3：

Step 401, terminal generates map according to physiological data and index, map include electrocardio map, pulse wave map, skin Electrograph spectrum and body innervation answer map, and index includes blood pressure index and heart rate index.When people can be due to nervous and sweat gland when lying Secretion influences physiological data and exception occurs, and the terminal can analyze the physiological data of testee to judge whether testee says Lie.

Step 402, analysis skin electrograph spectrum, now skip a grade or the phenomenon that fluctuates widely if skin electrograph is composed, then follow the steps 403, if skin electrograph spectrum does not occur phenomenon of skipping a grade or fluctuate widely, export the result that do not lie.

Skin resistance refers to the variation of the skin resistance of people, it is considered that this variation and the sweat gland of skin of people have closely Connection, control by sympathetic nerve, when testee has the performance of muscle slightly trembleed or have the anxiety such as sweat, can be caused Muscle electric discharge, cause skin electricity skip a grade or the phenomenon that fluctuates widely.

Now skip a grade or the phenomenon that fluctuates widely so being composed such as pericarp electrograph, one can consider that testee is at least tight , but can not need further to judge electrocardio map in this, as the judgment criteria that testee lies.

Step 403, analysis electrocardio map；If electrocardiogram composes existing electromyogram reaction, thens follow the steps 404 or execute step 406；If electrocardio map does not occur electromyogram reaction, the result that do not lie is exported.

Electrocardiogram is the figure for recording the variation of electrical activity caused by heart each cardiac cycle, when the heart rate of testee is When normal, electrocardio map is also periodically to fluctuate, but if will be produced when testee's anxiety on its electrocardiogram Electromyogram reaction, i.e., the waveform to get muddled in electrocardio map, it can be determined that testee be it is doubtful lie, at this time can be into One step judges blood pressure data, can also directly judge that body innervation answers map.

Fig. 3 is not show the electrocardio map that material measures of detecting a lie to testee, as can be seen from the figure the heart of testee Dynamic is loop cycle, and Fig. 4 is electromyogram map, i.e., testee generates the nervous electrocardiogram that influences and composes existing flesh after being stimulated Electrograph reaction, can be obvious from figure find out the variation of map, so the knowledge of detecting a lie that tester does not need profession can also be with Judgement show that testee has the possibility lied directly from map.

Step 404, analysis blood pressure data then follow the steps 405 or execute step if apparent increase occurs in blood pressure data 406；If the blood pressure data does not occur apparent increase, 406 are thened follow the steps.

When people is in anxiety, blood pressure will appear apparent increase, so when blood pressure data occurs significantly raised, it can be determined that by Survey person is doubtful to lie, and can further judge heart rate data, can also directly judge that body innervation answers map, but due to blood Pressure data are used only to do auxiliary judgment, so even if blood pressure data does not occur apparent increase, it is also desirable to further judge body Innervation answers map to determine whether testee lies.

Step 405, analysis heart rate data, no matter whether the heart rate data there is apparent increase, is performed both by step 406.

When people is in anxiety, heart rate will appear apparent increase, is reflected as heart rate data and significantly raised or pulse map occurs Fluctuate widely, it can be determined that testee be it is doubtful lie, can further judge that body cardon is composed, but due to heart rate Data are used only to do auxiliary judgment, so even if heart rate data does not occur apparent increase, it is also desirable to further judge that body is dynamic Map is incuded to determine whether testee lies.

Step 406, analysis body innervation answer map, if body innervation answers map to fluctuate widely phenomenon, illustrate testee with The variation of upper various physiological datas may be the movement generation due to testee's body, so judge that testee does not lie, it is defeated The result that do not lie out；If body innervation answers map without the phenomenon that fluctuates widely, illustrate that the body of testee does not move significantly Make, then exports the result lied.

That is, this lie detecting method is mainly by electrocardio map, skin electrograph spectrum and body innervation, to answer map tested to judge Whether person lies, and blood pressure index and heart rate index are as auxiliary judgment.

I.e., it is possible to judge that testee is the case where lying and is：

1) skin electrograph, which is composed, now skips a grade or the phenomenon that fluctuates widely, and electrocardiogram composes existing electromyogram reaction, and body is dynamic Answer map without the phenomenon that fluctuates widely；

2) skin electrograph, which is composed, now skips a grade or the phenomenon that fluctuates widely, and electrocardiogram composes existing electromyogram reaction, and blood pressure number It is significantly raised according to occurring, and body innervation answers map without the phenomenon that fluctuates widely；

3) skin electrograph, which is composed, now skips a grade or the phenomenon that fluctuates widely, and electrocardiogram composes existing electromyogram reaction, and blood pressure number It is significantly raised according to occurring, and there is apparent increase in heart rate data, and body innervation answers map without the phenomenon that fluctuates widely.

General in the prior art only judge the data such as electric skin, heart rate or blood pressure, still, this needs strict control to detect a lie environment And condition, it needs testee to keep normal sitting position, is unable to voluntary activity, therefore be only used for detecting a lie for short time, but this hair Bright lie detecting method, introduces electrocardio map and body innervation answers atlas analysis, firstly, we can be very intuitive from electrocardio map It must find the performance of testee's anxiety, i.e., the waveform to get muddled in electrocardio map.

Finally, analysis body innervation answers map, do not need testee and be always maintained at normal sitting position, generates life when testee moves When managing data variation, map can be answered to exclude the data of the variation by body innervation, eliminate the interference of testee itself, protected Card can be detected a lie for a long time without interrupting.
