Design Of Key Technology Of Mobile Terminal For Intelligent Care Of The Aged Based On Beidou Satellite

With the intensifying of the aging problem,Chinese traditional care of the aged model has already failed to meet the social needs.The rapid development of sensing technology and network technology has resulted in the emergence of intelligent care of the aged.Intelligent care of the aged is designed to provide more convenience for the elderly and provide young people with the possibility to balance their careers and families.At the same time,the Beidou positioning and navigation system,developed by our country,has been widely used in the fields of road traffic management,railway intelligent transportation,maritime transportation and air transportation.,and has also improved Chinese national defense capability.A remote monitoring system of intelligent care of the aged is proposed for the question of elderly remote monitoring,which is based on Beidou positioning,physiological monitoring,wireless data transmission and Android mobile terminal technology.The system consists of three parts: the hand-held detection terminal for the elderly,the monitoring application of the guardian,the system server of the control center.The main work accomplished in this paper includes two parts:(1)This paper has carried on the selection,the circuit design and the programming realization work of each module of the detection and positioning terminal.The Beidou positioning technology was used to obtain the elderly location information;The heart rate and body temperature of the elderly were perceived by using two photoelectric sensors;GPRS network was applied to transmit positioning and detection data;The STM32 act as a processor to detect and locate the terminal.The detection and positioning terminal realized the function of daily detection of heart rate and temperature,and saved the data in the database,and sent the positioning information to the guardian through the GPRS network when the elderly had an abnormal body condition.(2)This paper designed an android application for remote monitoring.The guardian could obtain real-time physiological detection parameters and positioning monitoring data by logging into the application.The android application realized the function of real-time remote detection of the physical state of the elderly and had the ability for the guardian to check the current real-time positioning of the elderly when the heart rate or body temperature was anomaly.Experiments show that the remote monitoring system of intelligent care of the aged has the function to real-time data acquisition,processing,storage and remote transmission,and can be used to solve the problem of remote monitoring of elderly people in the construction of intelligent care of the aged.The advantage of the system lies in the use of multiple photoelectric sensors to collect data,and can display historical data of physiological parameters through a line chart.More comprehensive data allows children to understand the physical status of the elderly using historical data.
