By the electric digital data transmission of brain after amplification to microprocessor kernel 300.
The brain electric analoging signal that the input of multichannel analog-to-digital conversion module 500 collects for electrode, it is preposition by signal acquisition
Partly, polarizing voltage fine setting module, signal amplifier and analog-to-digital conversion module composition.Electrode can use dry electrode, flexible electrical
Pole or other electrodes etc..The signal source impedance of human brain is high, and scalp generally has several kilohms of resistance with skull, it requires
Signal acquisition preamble part has very high input impedance, and ability is asked for improve EEG signals, typically enters impedance and is greater than 10M
Ω.Electrode and skin contact impedance is asymmetric etc. that position that factor can contact in electrode with scalp produces potential difference, referred to as polarizes
Voltage.The biasing of its General Influence signal, so polarizing voltage fine setting module is processed in front end, in favor of the extraction of signal.

Degrees of data and temperature data are transmitted to microprocessor kernel 300.
Wherein, corticocerebral temperature data and temperature data are used for the spirit and health status of auxiliary judgment user.Body
Temperature declines that to can result in blood circulation not smooth, and blood pressure rises, and hinders the burning of the energy such as sugar and fat in blood, can also hinder
The excretion of the wastes such as uric acid, pyruvic acid, easily triggers the illnesss such as hyperglycaemia (diabetes), high fat of blood and gout.In addition, body temperature is low
Also it is relevant with mental illness.People with depression and neurosis generally in temperature and body temperature all relatively low morning spirit not
It is good, afternoon temperature and body temperature rise, mental status will take a turn for the better.

Equally, the blood pressure of the mankind is also constantly in cyclically-varying.The change of blood pressure mainly includes seasonal variations, day-night change etc..
The formation of blood circadian is beneficial to adapting to body activities, protection cardiovascular activity and function.Human blood-pressure is also by very
The influence of many extraneous factors, such as moves, drinks, smoking and excited.
Blood oxygen saturation is to be combined O in whole blood volumes2Capacity accounts for all combinative O2The percentage of capacity.Exhale
Inhaling difficulty causes oxygen intake amount limited, and the blood oxygen saturation detection of respiratory system patient is critically important, on the one hand expiratory dyspnea meeting
Cause to take the photograph hypoxgia, on the other hand, continuing for asthma can also make tiny branch organ be blocked, and occur gas exchanges difficult,
Cause anoxic, cause the even damage of kidney in various degree of cardiopulmonary, brain.
Pulse is the beating of superficial artery.People is when motion and anxiety, it may appear that the situation of palpitating speed.Normally
The pulse of people is consistent with heartbeat.When atrial fibrillation or take place frequently proiosystole when, pulse and heartbeat occur inconsistent.

The light emitting diode of saturation degree pulses measure module 700 sends instruction by microprocessor kernel 300 and is controlled, microprocessor kernel
The optical signal that 300 pairs of photodiodes are received is filtered and amplified, and by receiving signal digital.The module generally comprises two
Individual light emitting diode, the light emitting diode of multiple different-wavebands can also be carried in order to improve precision.One diode discharges ripple
A length of 660 nanometers of light beam, another discharges 905,910 or 940 nanometers of light beam.Oxygen containing hemoglobin is to both ripples
Long absorptivity is very big with oxygen-free difference.Using this property, the ratio of two kinds of hemoglobins can be calculated.According to
Beer-Lambert (lambert Bill) law, feux rouges and infrared optical absorbance are with respect to change measure and arterial oxygen saturation
Functional relation should be linear relationship, but because biological tissue is a kind of strong scattering, weak absorbing, anisotropic complicated optical system
System, not in full conformity with classical Beer-Lambert laws, thus result in expression feux rouges and the relative change of infrared optical absorbance
The Mathematical Models of relation are difficult between measured value, with arterial oxygen saturation.Therefore, determined by the method for experiment pair
It should be related to, i.e. calibration curve.The circuit of the measurement multiplexing oxygen saturation measurement of blood pressure and pulse, only in micro-processor kernel
Write different programs, you can calculate blood pressure and pulse.
