基于射频技术的隧道人员定位基站优化布设研究

Research on the Optimal Layout of RFID Base Stations for Locating Tunnel Workers

在隧道安全事故中,对被困人员的快速定位可提高搜索速度、减少救援时间,对于保障隧道施工人员人身安全具有极为重要的意义.鉴于现有研究在隧道实时定位技术上的欠缺,本文利用射频技术快速识别、准确定位、成本低廉的优势,同时借鉴室内定位的LANDMARC算法,开展基于射频技术的隧道人员定位基站优化布设技术研究,以实现对施工作业人员的实时准确定位.经验证,本文所提出的布设方法可实现无死角覆盖及低成本建设,具有重要的推广价值.

In tunnel accidents,it has important implications to locate the trapped workers quickly,and it can improve the search speed and reduce the rescue time. The existing research on location technology in the tunnel is poor,so this paper makes a full use of the advantages of RFID（ Radio Frequency Identification） ： rapid identification,accurate location,and low cost. In reference to the LANDMARC algorithm for indoor location applications,this paper studies on the optimal layout of the base stations to accurately locate the workers in the tunnel in real time. The process of layout design is divided into two stages： the layout in the completed area and the layout in the construction area. According to the theoretic verification,this layout method can realize the coverage without dead angles and the low cost of construction,and the most important is that it has important promoting value.
