The Research Of Wearable Devices In Aged Chronic Disease Monitoring System

With the increasing demand for the monitoring of physiological indicators in terms of physical health and medical aspects in recent years,it has provided favorable conditions for the development of wearable monitoring system due to the development of wireless communication.Based on above conditions,we study and design the medical wearable devices.In this paper,the measurement of temperature,heart rate,blood oxygen,and numerical display are elaborated by research and design wearable devices.The wearable device consists of seven hardware circuits:the main controller,power supply system,OLED display module,wireless communication module,key module,temperature measurement part and heart rate oxygen measurement part.The main controller is the ARM Cortex-M3 architecture STM32 series processors and wireless communication module using ZigBee module.In this paper,the design process details of hardware circuit is given and the whole system is designed.For the software system of the device,it is completed by Keil MDK integrated development environment according to the system requirements.In the study,by analyzing the physiological features of human being and characteristic of sensor,data of A/D acquisition is processed by software filter so as to achieve better results for further research.In this paper,the hardware and software of the wearable device are analyzed from initially hardware design to finally completion by debugging,simulation and testing.
