摘要:
为了增强测量系统中的线性度和精度,将LQI测距法应用于室内定位系统中.在基于ZigBee的硬件平台上,结合室内环境进行了测距实验,并建立了经验模型.实验结果表明,LQI在短距离测量中有较好的线性度和精度,在室内测距的应用中效果较好.
Abstract:
In order to enhance the linearity and prec ision of m easurem ent system, a new me thod of d istance m easuring based on LQ I is applied to indoor lo ca lization system in th is paper. Exper im ents are carr ied out on ZigBee-based hardw are p la tform s in indoor circum stance. A ccording to the experim enta l data, the sc ientific m odeling o f indoo r d istance m easurement is produced. The resu lts indicate that LQI has a good linear ity and precision on m easur ing sho rt distance, and can ach ieve be tter results in indoor distancem easurem ents.
