基于物联网的活动范围受限人员监管系统的研究

Research of Monitoring System for Persons with Limited Range of Activities Based on IOT

首先介绍了活动范围受限人员监管系统的需求和研究意义,之后给出了系统的总体架构.在此基础上,着重介绍了基于RSSI(Received Signal Strength Indication)的测距原理和高斯模型校验方法,以及利用陀螺仪传感器通过航位推测算法进行方位计算的思想与方法.系列测试和实验结果表明,采用的RSSI测距方法和航位推算方法设计的系统可以有效的应用于活动范围受限人员的监管.

The requirements and significance of monitoring system for persons with lim- ited 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.
