Fall Detection and Monitoring System For Elderly Person
Falls in the elderly have every so often been serious medical and social problems. Fall detection is a foremost task in the public healthcare area, particularly for the elderly and consistent system is a need to alleviate the sound effects of falls. An effective fall detection system is essential to bring critical support and to considerably reduce the medical care costs related with falls. The persons above 70 years of age were dead produced by fall incident. Hence we need consistent user based fall detection system. This fall detection system is proposed for elderly person monitoring which is based on smart sensors worn on the body and working through home networks. The key part of this system is ARM 7 Microcontroller. To detect the unintentional falls, a small low power tri-axial accelerometer is used and to detect heart rate cardio tachometer sensor is used. This specified 3-axis accelerometer sensor is used to measured acceleration of the body in all the three axes. By using information composed from an accelerometer and cardio tachometer the effects of falls can be noted. The system will also send the location of the person using GPS. Location information, which gives the information of longitude and latitude. The fall detection can be described as the rapid change from the front, right, left, back fall position information. The family members know how to, with permission, access this information and consider the safety of the elderly person. The system will contact the emergency center instantly through text message using GSM modem.
