| Abstract: | The requirements and significance of monitoring system for persons with limited range of activities are introduced,in the first place.Then,the overall architecture of this system is given.On this basis,the distance measurement principle based on RSSI and the validation method with Gaussian model is highlighted.And,the position calculating method through dead reckoning algorithm with gyro sensor is focused on.A series of tests and experiment results show that,the system with RSSI distance measurement method and dead reckoning method can be effectively applied in monitoring persons with limited range of activities. |
