Development And Research Of An Elderly Electrocardiographic Mutation And Location Alam System

In this paper,we combine sensor technology,Bluetooth technology,GPS positioning technology and Android development technology to propose an elderly electrocardiographic(ECG)mutation and location system.Its purpose is to solve the series of problems that arise from the severe old-age pension situation in China,which is "not rich before getting old".When the elderly suffer from an abnormal electrocardiogram,the system can accurately locate and send a distress signal to facilitate the timely rescue of the elderly relatives and medical staff of the nursing homes.The system provides the elderly with a first-aid positioning and portable ECG monitoring function.It is equivalent to the current ECG monitoring equipment on the market.And,the system has the characteristics of low power consumption,long battery life,easy operation,low price,accurate positioning and help timely.Ultimately,ensure that the harm that may be caused when the elderly is unaccompanied is minimized.The system consists of two parts,the lower computer and the upper computer.The lower machine includes four parts:control core,ECG acquisition module,Bluetooth communication module and GPS positioning module.The microcontroller STC15W4K56S4 is used as the controller core of the lower computer.The ECG acquisition module selects the sensor MAX30102.Using the model hc-05 Bluetooth module for the data transmission between the lower computer and upper computer.Finally,using the model NEO-6M for GPS positioning module which determines the location information.The upper computer uses the Android Studio development tool to design an Android mobile phone client named "Heartbeat Mutation and Positioning Assistant".It is easy to operate.Moreover,its functions include registering login,bluetooth connection,viewing ECG data,help timely,personal information management,and display the elderly real-time geographic location information."Heartbeat Mutation and Positioning Assistant" is not only suitable for the elderly who uses the lower computer,but also for the elderly relatives and medical staff.Each module of the lower unit has a small volume,and the largest size is a Bluetooth module of 27mm*13mm,which can be made into a wristband after processing.The elderly can carry out real-time monitoring of their own ECG signals without affecting normal life,just by carrying a special wristband with them.The paper reports the design and debugging results of the system.It basically achieves the help and positioning of the elderly with abnormal electrocardiograms.It is of great significance for relatives and pension institutions of the elderly to monitor the situation of the elderly in time and to ensure that "the elderly is safe".And it has a wide range of applications.
