This work proposes an improved Real Time Localization System using UWB technology, for people and asset tracking in a closed environment, particularly in underground mines. The UWB technology has demonstrated a very good performance with a localization error margin below 41 centimeters. The main objective of this work was to develop an affordable, easy to use, and scalable localization system to detect people in underground mines that allows fast location and rescue in case of disaster. It can also improve the mine productivity under normal conditions. Different tests were carried out in mines and urban buildings to validate the design and evaluate the error margin. The test in an underground mine was done at “Casposo Mining”, which is located in the town of Calingasta, San Juan province, Argentina. Finally, an autonomy of 25 hours of continuous used was achieved using a 2000mAh battery.

使用 UWB 的地下矿井人体实时定位系统


这项工作提出了一种使用 UWB 技术改进的实时定位系统，用于封闭环境中的人员和资产跟踪，特别是在地下矿井中。 UWB技术已经展现出了非常好的性能，定位误差范围低于41厘米。这项工作的主要目标是开发一种经济实惠、易于使用且可扩展的定位系统，用于检测地下矿井中的人员，以便在发生灾难时快速定位和救援。在正常情况下还可以提高矿山生产率。在矿山和城市建筑中进行了不同的测试，以验证设计并评估误差范围。此次地下矿山测试是在位于阿根廷圣胡安省卡林加斯塔镇的“Casposo Mining”进行的。最终，使用2000mAh电池实现了连续使用25小时的自主性。
