Design And Implementation Of GPRS Wireless Communication For Monitoring The Health Of The Elderly In The Distance

With the rapid development of computer technology and Internet technology, the emergence of all kinds of new electronic products is gradually changing the way of people's life. People pay more and more attention to Internet technology, especially foreign children unable to real-time access to the health of old man. Of this phenomenon, this paper proposes a health remote testing system based on GPRS wireless communication, is the old man can't time at different children guardianship independent life health and put forward a solution. The solution to the existing intelligent bluetooth bracelet as health data collection tool, home gateway is used to receive the old man health data and processing, with the Internet as a carrier to fit the data sent to the remote client, to make install remote client children can know the old man's health at any time.In this paper, the old man health remote monitoring system mainly consists of data collection, transmission and processing, the design of hardware and software part of the family gateway. Hardware part as STM32F103 microcontroller core, bluetooth is used to send and receive data and GPRS network data transmission as auxiliary.Bluetooth part used to receive health data from the bracelet, GPRS part used to transport gateway health data after processing. The normal operation of the software part controls the gateway and ensure the real-time transmission of data to the remote client.This paper deeply analyses the bluetooth communication protocol and GPRS communication protocol, home gateway send data request to the bluetooth bracelet,in order to get the old man body data feedback, the old man body data obtained feedback, Using GSM network of the AT command to sent data by PDU encoding.Through hardware and software work together, complete the remote monitoring to the health of the elderly at home, although we don not have to accompany beside the old man,we also can easily know the physical of the old man condition in the home, it solve the separation of hand ring and mobile data connection problem.
