The Design Of Elderly Health Care Sysytem Based On Wireless Heterogeneous Networks

With the continuous development of social economy and culture level,Old people gradually realize the importance of health to yourself,But also in gradually upgrade and change their concept of health.China's aging population increasing,The life of old people demand for medical and health care are also growing,But China's serious shortage of health resources nursing home.Elderly health service construction must keep up with the need of modern the elderly,this is the inevitable requirement of social development.The whole framework of the elderly health care system and the main components and application of system function is designed in this paper.Which focuses on wireless gateway and wearable terminal node hardware design and software design,Communication protocol between heterogeneous networks and positioning of personnel.In the aspect of hardware,the design of the wireless gateway ZigBee coordinator and Wi-Fi controller part and Routing nodes and wearable terminal nodes.Wi-Fi wireless gateway controller part adopts CC3200 wireless chips,Wi-Fi controller to join the nursing home router,the ZigBee network data through the Wi-Fi network transmission to the Internet cloud platform.Wearable terminal node selection CC2530 radio frequency chip,ZigBee network to achieve data processing and RF transceiver function.In the aspect of software,Through the study of application system functions,Designed a wireless gateway in the Wi-Fi controller to connect the router to achieve the wireless gateway and the Internet cloud platform communication and Wi-Fi controller through serial interface and ZigBee coordinator of information interaction,Wi-Fi controller through the establishment of ZigBee network protocol conversion and data fusion methods and the Internet cloud data communication platform,in order to achieve data transmission system.Personnel positioning,through the distance calculation model based on RSSI algorithm to implement the personnel positioning.At the end of this paper,the elderly health care system is tested,Test results show that,the elderly health care system is based on the wireless heterogeneous network,Terminal nodes of the sensor data collection,based on the protocol conversion of heterogeneous network communication system,real-time monitoring and personnel orientation function,can meet the application requirement of elderly health care system.
