光通信室内定位接收信号强度两点定位 optical communication indoor positioning received signal strength two-point positioning

摘要

针对可见光通信中基于接收信号强度的三边定位法在实际中难以应用的现状,提出一种基于可见光通信的室内两点定位模型,只需2个LED,能够克服定位需要多灯环境的限制,同时定位接收端结构简单,不需以往研究中的复杂设计,只在平面上配置3个光电探测器即可。利用收发两端的位置关系计算坐标的可能解,以光电探测器组合成的三角形具有相对位置不变的性质作为判据,判断出真实坐标完成单点定位,最后进行加权定位提升鲁棒性。不降噪处理时,大小适中的接收端在5m×3m×3m的室内环境中,55%以上区域的定位精度在25cm以内,同时能够有效克服接收端水平旋转或上下抖动对定位效果的影响,具备实际应用价值。

Abstract

Aiming at the current situation that the trilateral positioning method based on received signal strength in visible light communication is difficult to be applied in practice, a new indoor two-point positioning model based on visible light communication is proposed, which requires only two LEDs to overcome the need for multi-lamp environment for positioning. At the same time, positioning the receiving end structure is simple, without the complicated design in the previous research; only three photodetectors can be arranged on the plane. By using the positional relationship between the two ends of the transmitting and receiving to calculate the possible solutions of the coordinates, the triangles combined by the photodetectors have the relative position-invariant property as the criterion, and the real coordinates are determined to complete the single point positioning, and the weighted optimization improves the robustness. Experiments show that the positioning performance of the receiving end is affected by factors such as PD combination size, horizontal position, vertical height, angle, and up and down jitter when the noise source is determined. When the noise reduction processing is not performed, the receiving end with moderate size is in the indoor environment of 5m×3m×3m, and the positioning accuracy of more than 55% of the area is within 25cm, which can effectively overcome the influence of horizontal rotation or up and down jitter of the receiving end on the positioning effect. The model has practical application value.
