本文讲解了zigbee技术在高层建筑定位系统中的设计,其中包括参考节点,定位节点,网关等。利用MATLAB对三边测量法、三角形质心定位算法这两种定位算法进行仿真模拟,通过对定位算法的仿真模拟得知三角形质心定位算法的精确度相对比较高,将使用三角形质心定位算法作为该系统的定位算法。最后使用监控软件对该系统进行调试,测试其稳定性。测试结果最高精度可达1 m左右,其定位误差能控制在3 m以内,已大致满足高层建筑日常定位需求。
This article explains the zigbee technology in high-rise building positioning system design, including reference nodes, positioning nodes, gateways and so on. Using MATLAB to simulate the three positioning algorithms of triangulation and triangle centroid positioning algorithm. Through the simulation of the positioning algorithm, we know that the accuracy of the triangle centroid positioning algorithm is relatively high, and the triangle centroid positioning algorithm will be used as the system The location algorithm. Finally, the use of monitoring software to debug the system to test its stability. The highest accuracy of the test results is about 1 m, and its positioning error can be controlled within 3 m, which basically meets the daily positioning needs of high-rise buildings.
