Abstract

The purpose of this study is to investigate the effects of environmental and human factors on communication attenuation as well as to improve radio signal attenuation. In this study, a fire training containerized structure for firefighters and commercial rescue portable radios were used for a communication experiment in a fire scene. It was found that the firefighter’s relief communication posture reduced radio communication power. The prone posture had the greatest effect on radio communication attenuation. Also, smoke caused a decrease in communication power regardless of flame burning conditions or temperature effects. The results of the study showed that the communication power can be improved by changing the radio antenna orientation and operating the radio in a non-dense smoke layer. Finally, this study proposed that a new portable radio protection bag with thermal protection designed for firefighters wearing radios on oxygen cylinder straps could effectively improve the communication attenuation problem.
火灾期间消防员操作无线电衰减的研究
本研究旨在探讨环境与人为因素对通信衰减的影响,以改善无线电信号衰减。本研究采用消防训练集装箱结构和商用救援便携式无线电在火灾现场进行通信实验。发现消防员的救援通信姿势会降低无线电通信功率。俯卧姿势对无线电通信衰减的影响最大。此外,无论火焰燃烧条件或温度影响如何,烟雾都会导致通信功率下降。研究结果表明,通过改变无线电天线方向和在非密集烟雾层中操作无线电可以提高通信功率。最后,本研究提出了一种新型的便携式带热保护的无线电保护袋,用于在氧气瓶带上佩戴无线电的消防员,可以有效地改善通信衰减问题。

期刊介绍: The Journal of Fire Sciences is a leading journal for the reporting of significant fundamental and applied research that brings understanding of fire chemistry and fire physics to fire safety. Its content is aimed toward the prevention and mitigation of the adverse effects of fires involving combustible materials, as well as development of new tools to better address fire safety needs. The Journal of Fire Sciences covers experimental or theoretical studies of fire initiation and growth, flame retardant chemistry, fire physics relative to material behavior, fire containment, fire threat to people and the environment and fire safety engineering. This journal is a member of the Committee on Publication Ethics (COPE).
