Human Physiological Parameter Acquisition System Of Intelligent Pension

In China, large population and rapid growth of the old make aging society becoming severer. The problem of one-child and medical care shocks traditional pension. An innovative pension called intelligent pension was proposed as information, big data and Internet of things are coming. All kinds of sensor terminals connect to computer networks by Cloud Computing and Internet of things.Based on the above-mentioned background, the human physiological parameter acquisition is proposed in this paper, including the collection and display of the physiological parameters. There are body temperature, heart rate and ECG in this system. The following is a detailed introduction of the detection techniques:Temperature detection module is sampled by NTC (negative temperature coefficient) thermistor, according to the change character of electrical resistivity with temperature, voltage and temperature indirect characteristics, fitting curves to get corresponding quadratic functional relations between voltage and temperature by IBM SPSS (statistical product and service solutions) software, finally we can obtain the values of the corresponding temperature according to the voltage.Heart rate detection module is sampled by pulse sensor and pulse wave is obtaine d according to the photoplethysmograph pulse wave.We can obtain the mean time bet ween the wave and the wave and calculate a pulse rate in 60 seconds by the appropriat e processing of pulse wave.That is, the heart rate.ECG detection module is sampled by AD8232 integrated signal conditioning module, which has the function of filtering, amplification and other signal processing. It filters and displays the ECG waveform through the noise characteristics of the ECG signal.
