Abstract  In order to prevent the collision between lifting goods and barrier in the process of running, the principle of ZigBee wireless location was introduced, and the loss model of radio was analyzed. The positioning reference node was optimized layout according to structure characteristics of tower crane, and the localization algorithm was simplified. RSSI values were filtered by using Gaussian theory, and the distance was calculated by the logarithmicnormal distribution theory model. Finally, the blind node coordinates were obtained according to the threedimensional positioning method. The experiment was made in real environment, the results shows that this method can realize the positioning accuracy in 2.5 m. It provides the reference for design of location collision avoidance system and realtime monitoring system of tower crane.

Key words： tower crane hook positioning      three-dimensional positioning method      ZigBee      wireless location technology

基于ZigBee的塔机吊钩定位算法

为了防止塔机运行过程中起吊货物与障碍物发生碰撞，介绍了ZigBee无线定位的原理，分析了无线电传播损耗模型.根据塔机的结构特点优化布置定位参考节点，简化了定位算法；采用高斯理论模型过滤RSSI值，利用对数正态分布理论模型计算距离; 最后应用提出的三维定位算法求得盲节点坐标.在实际环境中进行了实验，实验结果表明，该算法可实现定位精度在25 m以内的定位，为塔机定位防撞系统设计、塔机的实时监控提供了参考依据.
