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.
First of all, it introduces the demand and research significance of the system of limited personnel supervision of the scope of activities, and then gives the overall architecture of the system.On the basis of this, the principles of distance measurement based on RSSI (Received Signal Strength Indication) and Gaussian model verification Method, and the idea and method of using azimuth sensor to calculate azimuth by dead reckoning algorithm.The series of tests and experimental results show that the system designed by RSSI ranging method and dead reckoning method can be effectively applied to the field of limited range of activities Personnel supervision.
