摘要

摘要: 针对现有井下人员定位技术定位精度较低的问题，通过分析电磁波、超声波测距原理及在井下巷道的应用特点，提出了一种井下电磁波超声联合定位方法。该方法根据对数-常态分布模型，通过近似运算得到移动节点到2个锚节点的距离之比，以电磁波测距方法得到移动节点的纵向坐标，以超声波测距方法得到移动节点的横向坐标。Matlab仿真结果验证了该方法的可行性及精确度。

Abstract: For low localization precision of existing underground personnel localization technologies, an underground joint localization method based on electromagnetic wave and ultrasonic was proposed by analyzing ranging principle of electromagnetic wave and ultrasonic wave as well as application characteristics in underground tunnels. In the method, a ratio of distance between a mobile node and two anchor nodes is obtained by approximate calculation according to logarithmic normal distribution model. Vertical coordinate of the mobile node is obtained by electromagnetic wave ranging method, and horizontal coordinate is gotten by ultrasonic wave ranging method. The Matlab simulation result verifies feasibility and localization precision of the method.
