摘要
为解决常规的模型存在比较明显的误差,定位时通常不能实现预期定位的问题,设计了一类室内定位系统。该系统很大程度上结合了标准化的RSSI(Received Signal Strength Indicator)测距模型,并应用了高精度的3边定位算法。实验表明,该系统能在很大程度上解决定位误差问题,误差减小15%,得到可靠的定位结果。
In order to solve the problem that there are obvious errors in the conventional models and the expected positioning cannot be realized, a kind of indoor positioning system is designed. The system adopts the standardized rssi ranging model. The experiment shows that the system can solve the problem of positioning error,the error is reduced by 15%,and the reliable result is obtained.
