The introduction of module and parameter declaration:
1, photoelectricity volume pulse transducer
According to langbobier law, material is directly proportional at the absorbance at certain wavelength place and its concentration.When the illumination of constant wavelength is mapped on the tissue, will reflect to a certain extent the architectural feature of illuminated position tissue by the light intensity that measures behind tissue absorption, the reflection loss.Pulse is mainly produced by human body artery diastole and contraction, at the human body finger tip, tremulous pulse component content in the tissue is high, and relative other people soma of finger tip thickness is thinner, it is relatively large to see through the light intensity that detects behind the finger, so the measuring point of photo-electric pulse transducer is usually at the human body finger tip.
Native system photoelectricity volume pulse transducer adopts OPT101 type sensor.OPT101 type sensor is that light harvesting sensing device and signal amplify the device in one, adopts single power supply, piezoelectricity output, and output voltage is linear change with the light intensity that shines light-sensitive device.OPT101 type sensor internal circuit structure as shown in Figure 8.
The feedback network that 1M Ω and 3pF form in the application sheet, soon pin 4,5 connections namely consist of basic application circuit, this sensor is positioned at the B of system part, at this moment relation such as Fig. 5 of the output amplitude of circuit and irradiation light wavelength, and the angle of incidence of irradiation light and the relation of output amplitude are as shown in Figure 6.
2, pressure transducer
Mechanics sensor of a great variety is such as resistance strain gage pressure transducer, semiconductor gauge pressure transducer, piezoresistive pressure sensor, inductance pressure transducer, capacitance pressure transducer, and resonance type pressure sensor etc.But what be most widely used is piezoresistive pressure sensor, and it has extremely low price and higher precision and linear characteristic preferably.
The blood pressure measurement module of native system is selected BP01 type pressure transducer, it be for Monitoring of blood pressure custom-designed, adopt the encapsulation of accurate thick film ceramic chip and nylon plastic(s), have high linearity, low noise and the little characteristics of extraneous stress, its inner equivalent circuit and outline packages are as shown in Figure 7.BP01 has adopted inner demarcation and temperature-compensating mode, thereby precision, the stability and repeatable measured have been improved, in the gamut scope, precision is ± 1%, zero point, imbalance was not more than ± 300 μ V, the blood pressure measurement scope of this blood pressure measurement module is 0～200mmHg, and resolution is 0.1mmHg.
3, acceleration transducer
Because native system need to carry out fall detection, therefore adopt acceleration transducer.
Native system adopts the three axially low gravity accelerometer MMA7260Q based on MEMS (MEMS) of Freescale exploitation, and this is a low-cost minisize condenser type acceleration transducer.This chip has adopted signal condition, single pole low-pass filter and technique for temperature compensation, it is a single-chip device, have three axial measuring abilities, read falling, tilt, move, place, shake and waving of low gravity horizontal with high sensitivity, make native system intelligently response position, orientation and mobile variation.The MMA7260Q package dimension is very little, only needs less board space, and quick startup and park mode also are provided in addition, reaches the requirement of native system low-power consumption.
The MMA7260Q chip is widely used in each field, and for different application, the acceleration of gravity rank has different selections, and what the human body fall detection was applicable in the native system is the rank of 1～2g.MMA7260Q three axle acceleration sensors are the sensors that detect object motion and direction, and it changes the magnitude of voltage of output signal according to object motion and direction.The signal of each axle do not move or not by the state of action of gravity under (0g), it is output as 1.65V.If along some direction activities, perhaps be subject to action of gravity, output voltage will change according to the transducer sensitivity of its direction of motion and setting its output voltage, reads this output signal with the A/D converter of single-chip microcomputer (G), just can detect its motion and direction.
4, the Sampling Compression of compressed sensing and signal
A key foundation of modern signal processing is Shannon Sampling Theory: a signal can be determined by its bandwidth by the desired discrete sample number of undistorted reconstruction.But Shannon's sampling theorem is the abundant inessential condition of a signal reconstruction.Compressed sensing is as a new sampling theory, and it can at the discrete sample that obtains signal under the condition of nyquist sampling rate, guarantee the undistorted reconstruction of signal.
The core concept of compressive sensing theory mainly comprises 2 points.First is the sparsity structure of signal.Traditional Shannon sampled signal method for expressing has only developed the minimum prior information that is sampled signal, the i.e. bandwidth of signal.But, a lot of wide concerned signals in the actual life, with respect to the degree of freedom of its bandwidth information, the construction features of signal self is determined by less a part of degree of freedom.In other words, be exactly in information loss situation seldom, sort signal can represent with digital coding seldom.So on this meaning, such signal is sparse signal (physiological signal that gathers in this utility model all is sparse signal for perhaps approximate sparse signal, compressible signal, empirical tests).Uncorrelated characteristic more in addition.The obtaining of the useful information of sparse signal can shorten signal pressure into less sample data by the method for sampling of a non-self-adapting and finish.The method of sampling of compressed sensing is one and simply signal is carried out relevant operation with one group of waveform of determining that it is incoherent with the evacuated space at signal place that these waveforms require.
The realization of compressed sensing in this utility model: at first use sensor acquisition measured's sign monitoring analogue signal and with its quantification, namely obtain the linear measurement of primary signal, follow the simulation/transcriber based on the compressed sensing theory, utilize a definite observing matrix (" the one group of waveform determined " namely above mentioned) to carry out matrix multiple with the sign monitor signal that quantizes, thereby realize compression, utilize rear end DSP restructural primary signal or directly calculate the information such as statistical data of primary signal.
Compression sensing method has been abandoned the redundancy in the current demand signal sampling, and it directly obtains compression samples from the continuous time signal conversion, then adopts optimization method to process compression samples in Digital Signal Processing.This also is inventive point of the present utility model place having played important function aspect saving data space of the present utility model, the reduction power consumption.
During use, cloth matter base band 1 is tied up to measured's chest locations, finger tip module 5 is worn on measured's thumb, sensor and optoelectronic induction ring are collected the human body physical sign key element, input main frame (single-chip microcomputer) carries out signal detection, processing, simultaneously information is presented on the flexible display screen, and determines whether report to the police and carry out warning of which kind of mode etc. according to the monitoring situation.
