Localization and indoor tracking of rescuers and victims are essential during emergency management in post-earthquake conditions because those allow search and rescue teams to be faster and more efficient. While several indoor tracking technologies have been developed over the past years, localization and tracking are still a challenge during emergency conditions when power and telecommunication networks are often missing. This article presents a new indoor positioning technique for emergency support that is based on the ultra-wideband network using fixed nodes (anchors) and moving nodes (tags) in the form of a smart watch. The main challenge addressed by the system design is a self-calibrating positioning that is able to transfer also the user’s vital signals parameters. This article describes the system architecture and the key aspects of the prototype components. Two applications for indoor tracking and emergency rescue are illustrated while the performance of the system is validated by performing tests in a complex building.

使用室内跟踪改进地震后应急响应

在地震后的应急管理过程中，救援人员和受害者的定位和室内跟踪至关重要，因为这可以让搜索和救援团队更快、更高效。尽管过去几年开发了多种室内跟踪技术，但在电力和电信网络经常缺失的紧急情况下，定位和跟踪仍然是一个挑战。本文介绍了一种基于超宽带网络的应急支持室内定位新技术，采用智能手表形式的固定节点（锚点）和移动节点（标签）。系统设计解决的主要挑战是自校准定位，它也能够传输用户的重要信号参数。本文描述了系统架构和原型组件的关键方面。说明了室内跟踪和紧急救援的两个应用，同时通过在复杂建筑物中执行测试来验证系统的性能。
