Real-time Monitoring System Of Human Health Indexes

In recent years,with the ageing of population and younger of patients with chronic diseases of China's population are increasing day by day.High-quality and longer-term medical care has gradually become the focus of attention around the world.In the field of contemporary electronic medical,the development of family medical care system has become an important research direction,and as family medical equipment must have the characteristics of portability,real-time and multi-function.Accordingly,we designed human health indicators real-time monitoring system equipment which has a small size,high precision,real-time strong and easy to carry and operate,to collect the user's ECG,heart rate,blood pressure,body temperature and other physiological parameters.And Combined with Android intelligent mobile phone terminal to realize the physiological parameters' real-time transmission through the wireless.The article introduces the application background of the real-time monitoring system of human health indicators and the development of international and domestic research.And studies the theory knowledge related to this task,such as Android development environment,the JAVA language foundation,all kinds of sensor driver and ECG filtering algorithm,which provides a theoretical basis for the design of this system.In this paper,the hardware part of the MCU design using STM32F103RCT6 chip as the hardware platform processing core.ECG,heart rate data acquisition using BMD101 chip.Blood pressure measurement using FBP300 bridge-type pressure sensor.Temperature data acquisition using MLX90615 infrared temperature sensor.Wireless communication using CC2540 Bluetooth 4.0module.This system follows the principle of small size,low cost,antiinterference ability and real-time ability,conform to the design of portablefeatures.It is convenient for the user to wear in daily life.And developed a health care system based on Android mobile phone application.In the part of Android application,describes the overall framework of application development.Then respectively made a description in the achievement of software filtering,data communication,ECG graphics rendering,and data playback.And added an appropriate filtering algorithm in system to remove ECG interference data.In the filtering algorithm using the smoothing filter and the wavelet filter in the combination of the series filter algorithm.The design of this system in line with the design requirements of running stable,measuring accuracy and real-time and highly portable.
