为探索RSSI（Received Signal Strength Indicator）技术的应用，了解其测距原理及验证其准确性，经过多次实地测量，在不同距离下搜集多组接收信号的强度指示，通过数学软件，采用线性回归及多项式回归两种回归分析，研究其相关性，再比较、验证其精准性，选择出更符合原始数据的分析方法，得到RSSI和距离的关系。

Explore the RSSI (Received Signal Strength Indicator) technology, understand its location principle and verify its accu-racy, after several field measurements at different distances to collect multiple sets of received signal strength indicator, through mathematical software, used linear regression and two kinds of regression polynomial regression analysis, researched their rele-vance, and then compared, verified its accuracy. Chose the more in line with the analysis method of the original data, and ac-quired the relationship between RSSI and distance.
