[Abstract]:With the continuous development of society, people's awareness of health and the prevalence of sub-health, aging and other phenomena, patients are expanding, medical resources become more and more tense, People's health concept began to change from sick medical treatment to disease-free defense, and the health monitoring system which can monitor health status by itself has become an urgent need. According to the above-mentioned situation, this paper takes the monitoring of human heart electricity, blood oxygen, blood pressure and pulse as the starting point, and designs a set of real-time detection of human health information from the aspects of practicality, portability, expansibility, and so on. A health monitoring system that is uploaded to a data center for real-time monitoring via a wireless transmission function. In the ECG monitoring module, the disk electrode is selected and the standard bipolar limb lead is used. On the basis of analyzing the characteristics of ECG signal, ECG analog signals are obtained by pre-amplification, two-stage amplification and filtering processing. After AD conversion, ECG waveform transmission and storage and QRS detection are realized on the software. The blood oxygen monitoring module uses dynamic spectrometric method to transmit the finger with two kinds of light source, the wavelength of which is 660nm and 940nm, respectively. The transmitted light is converted by the photoelectric receiver and the amplified filter of the obtained electrical signal is converted by AD and the oxygen information of human blood is collected by software. The blood pressure monitoring module uses pressure sensor to convert the pressure signal produced by the change of pulse wave amplitude in blood circulation into voltage signal. The static pressure and pulse signal are extracted by low-pass and band-pass filtering, respectively. After AD conversion, the blood pressure value was calculated according to the amplitude coefficient method of oscillographic method in the software. The data aggregation center uses the S3C2440A chip of Samsung Company as the main control chip, uses the internal memory controller, the LCD controller and other resources and ZigBee wireless module to realize the display of the physiological parameters data. Storage and multi-parameter joint monitoring from the monitoring terminal to the data aggregation center. The system preliminarily realizes the monitoring and wireless transmission of many physiological parameters, and can monitor ECG, blood oxygen, blood pressure and pulse in real time. Each monitoring module is optional module, which improves the flexibility and expansibility of the system. It has played a positive role in the development of health monitoring system.
