摘要

摘要本研究提出了一个简单的基于位置的救援请求系统,用于有大量运动员参加的城市马拉松比赛。该系统不采用被动射频识别技术,而是采用主动蓝牙低能耗通信技术。当运动员受伤时,他们可以立即发送救援请求,其中包含他们估计的受伤位置和时间。一旦接到救援请求,医护人员就能迅速做出反应。本研究包括三个部分。首先,救援队接到受伤运动员请求所需的时间是根据过去的国际城市马拉松比赛记录估计的。然后,进行软件仿真,提取系统定位最简单的传递参数要求。最后,制作了实验样本进行现场验证,并开发了救援通知计时系统。该方法在3-4分钟内成功传递了97.4%-99.9%的运动员请求信息,并将救援地点的误差范围保持在15m以下。由于其结构简单、重量轻、成本低,并且只需要准备大规模生产的常见商业技术,因此适用于城市马拉松比赛。

Rescue notification system with accurate location estimation for injuries in city Marathons
ABSTRACT This study proposes a simple location-based rescue request system for use in city marathons with large numbers of athletes. Instead of using passive radio frequency identification technology, the proposed system employs initiative Bluetooth low-energy communication technology. When an athlete is injured, they can immediately transmit a rescue request that contains their estimated location and the time of the injury. Upon receiving the rescue request, medical staff can respond rapidly. This study included three parts. First, the time required for a rescue team to receive a request from an injured athlete was estimated based on past international city marathon race records. Then, a software simulation was performed to extract the simplest transfer parameter requirements for system positioning. Finally, experimental samples were produced for field verification, and the rescue notification timing system was developed. This approach was found to successfully deliver 97.4%–99.9% of the athletes’ request messages within 3–4 min and maintains the error range of the rescue locations under 15 m. It is appropriate for use in city marathons owing to its simple structure, low weight, low cost, and need for only common commercial technologies that are ready for mass production.

期刊介绍: The aim of this interdisciplinary and international journal is to provide a forum for the exchange of original ideas, techniques, designs and experiences in the rapidly growing field of location based services on networked mobile devices. It is intended to interest those who design, implement and deliver location based services in a wide range of contexts. Published research will span the field from location based computing and next-generation interfaces through telecom location architectures to business models and the social implications of this technology. The diversity of content echoes the extended nature of the chain of players required to make location based services a reality.
