应急救灾系统研究具有重要的实际意义,针对当前应急救灾系统被困人员定位性能差的缺陷,提出一种基于光纤传感器的应急救灾系统。首先介绍当前应急救灾系统的研究现状,并采用光纤传感器作为硬件核心构建应急救灾系统,然后针对被困人位定位问题,采用一种最小二乘法实现光纤传感器节点定位,最后在Windows XP实现了应急救灾系统,并进行了仿真模拟实验。结果表明,本文系统可以快速、准确得到了被困人员位置信息,是一种性能优良的应急救灾系统。
Research on emergency relief system has important practical significance. Aiming at the defect of poor positioning performance of trapped personnel in emergency rescue system, an emergency relief system based on optical fiber sensor is proposed. Firstly, the research status of the current emergency relief system is introduced, and the optical fiber sensor is used as hardware core to construct the emergency relief system. Then aiming at the location of the trapped person, a least square method is used to locate the fiber sensor node. Finally, Disaster relief system, and conducted simulation experiments. The results show that the system of this paper can get the location information of the trapped people quickly and accurately, which is a kind of excellent disaster relief system.
