The Design And Implementation Of The Integrated Collection System Of Human Physiological Parameters And Environmental Information Based On Android

At present,the aging of China's population is increasingly serious,and the number of sub-healthy people is increasing.In order to improve health security,it has become a new way of health management to collect various information of human body by wearable devices.Based on the research of the existing human monitoring system and analysis of the demand of people,this paper designs and realizes a kind of information integration based on the Android human physiological parameters and the acquisition system,the system can not only the physiological parameters acquisition,to grasp the user's state of health,can also be for environmental information collection,whether the user to understand the environment security,improve the security and comfort of users.In the process of development,this paper focuses on the acquisition principles and algorithms of human physiological parameters such as heart rate detection based on PPG(Photo Plethysmo Graphy),blood pressure detection based on PWTT(Pulse Wave Transit Time in the Artery)and blood oxygen saturation detection based on fitting calculation.Establishes a modular design,completed the integration of a variety of sensor module,bluetooth wireless transmission module and OLED(Organic Light-Emitting Diode)display module the master control center of the construction of the hardware platform and the development of control software,realizes the heart rate,blood pressure,blood oxygen saturation and human physiological parameters such as temperature and humidity and the concentration of combustible gas integration acquisition of environmental information,and in the local real-time display at the same time,according to the bluetooth transmission protocol transmitting data over a bluetooth module to the mobile phone client;At the same time,an android-based mobile APP(Application)was designed and developed,which realized the functions of data storage,waveform display,digital display,data storage and historical data query,so as to facilitate users to manage and view the data.Through this system software and hardware test and data analysis,proved that the system can realize the integration of the various parameters acquisition,it not only can be used for the old man's home care,but also can provide data support for the prediction of sub-health,have very strong practicability.
