| 摘 要： | 利用接收信号强度指示(RSSI--Received Signal Strength Indicator)定位因为其借助的设备较少,实现方法简单而被广泛应用;在简述利用接收信号强度指示(RSSI)定位原理的基础上,以生活实际中经常用到的蓝牙为例研究两个蓝牙设备之间的距离与接收信号强度指示之间的关系;并在三种具体环境中建立了相应的关系曲线图,虽然并没有给出具体的解析表达式,但仍然能在一定程度上反应设备间距离与RSSI的关系,并为进一步的研究打下了坚实的基础;得出了在空旷环境比室内以及楼道环境下信号传播效果要好,而且三种环境下信号强度都随着距离的增加而减小,在有障碍物的情况下比没有障碍物衰减更大。

| Abstract: | The method of using received signal strength indicator to locating is widely used because it uses only a few equipment and easy realization.This article based on the theory of RSSI locating,with the example of Bluetooth in our lives,studies the relationship between the RSSI and distance between the two Bluetooth equipments.And this article builds the relationship graph in three environments.Although it doesn't give the analytic expression,it also can show the relationship between the distance and RSSI at so... |
