Physiological State Monitoring System of the Home Elderly Based on Multi-frequency Narrowband Power Line Communications

Abstract

This paper designs and implements a home elderly physiological data monitoring system, which based on multi-frequency narrowband power line communications technology. The system combines wireless sensor network and narrowband power line communication method, realizes the real-time monitoring and transmission of the physiological status of the home elderly. This scheme overcomes the weakness that the traditional monitoring system using wireless network signal alone, there is no signal in the shielding area, then realizes no blind angle control in buildings. Finally, through the test and analysis, it proved that the system can meet the application requirements, and it is a suitable solution for home elderly physiological status monitoring.
