基于伪基站的地震废墟人员搜寻定位技术
Disaster relief based on Pseudo Base Stations

在地震救灾工作中，能否在短时间内搜寻并定位被困人员是考验应急救援工作的重要问题。快速的搜索定位可以显著地提高救援效率，减少人员伤亡和财产损失。针对大范围地震灾害发生后，搜寻范围大、搜救力量不足、搜寻时效性要求高的一系列问题，该文研究提出一种基于伪基站的大范围手机搜寻定位技术及其系统架构。通过在模拟的地震废墟地形中测试手机接收信号强度指示值（receive signal strength indicator，RSSI）与手机信号发射强度，对采集的数据进行分析以验证该系统在大范围地震废墟中的搜寻能力。实验测试和数据分析结果表明：该系统可以对大范围的手机进行搜寻定位，能够满足废墟、地下室等特殊环境下应急需求，并可以有效地提高人员搜救效率。
Abstract：The time for searching and locating victims in disaster-relief work is a key factor for the rescue efficiency. A fast search and locating operation can significantly reduce casualties and property loss. A cellphone search and locating system based on Pseudo Base Stations (PBS) is described in this paper to alleviate the problems caused by lack of rescue resources and large rescue areas. The receive signal strength indicator (RSSI) data and cellphone signal transmission power data were collected in simulated disaster areas. Then, data was analyzed to evaluate the effectiveness of searches in large disaster areas. The data analyses show that the system can search and locate cellphones in large areas for use by rescue teams in widely damaged areas.
