【摘要】 室内移动定位在商场购物、建筑节能、医疗护理、应急救援等领域中应用广泛。由于受复杂室内环境等条件的限制,目前室内定位方法往往精度不高,价格也较为昂贵。ZigBee是一种新兴的短距离、低速率无线网络技术,利用ZigBee技术实现定位具有低成本、低功耗的优点,且信号传输不受视距的影响。本文对各种室内无线定位技术进行了分析和比较,选择用XBee模块进行自组织组网,采用加权三角质心RSSI定位算法,提高室内定位精度,并通过实验证明该方法的可行性。更多还原

【Abstract】 Indoor mobile location are applied widely to the application field such as shopping mall, building energy saving, medical care, emergency rescue and so on. Due to the constraints from complex indoor environments, the indoor positioning methods have high precision hardly and the prices are high. ZigBee is a new short-range, low-speed wireless network technology. Using ZigBee technology to realize location has the advantages of low cost, low power consumption and signal transformation without influence of stadia distance .In this paper several indoor wireless location techniques are analyzed and compared with each other. XBee module is used to complete self-organization network. Meanwhile, Weighting Triple Centroid RSSI algorithm is adopted in order to improve the precision of indoor location. And the experiments prove that the method is feasible.更多还原
