| 摘 要： | 通过全尺寸实火试验和计算机模拟,分析和研究了地下工程火灾环境对无线信号传输效果的影响,并基于无线信号传输常规模型,假设地下工程火灾条件下的无线信号传输的数学模型,得出接受信号强度RSSI值的衰减与温度变化、烟气浓度变化的关系,通过分析数据之间的关系,得出地下工程中火灾环境下的无线信号传输损耗指数的值,最终建立起地下工程火灾环境下的无线信号传输模型.为复杂环境消防通信问题的研究奠定基础.

| Abstract: | Based on the real full - scale fire tests and computer simulations, this paper analyzes and studies the effects of the fire underground engineering on wireless signal transmission, and finds the relationship between attenuation of RSSI value with temperature changes and gas concentration changes based on the conventional model of wire- less signal transmission, on the assumption of an underground fire conditions wireless signal transmission mathematical model. radio signal transmission loss index values in underground engineering fire environment were obtained by the analysis of relationship between groups of data. Eventually, a wireless signal transmission model of under- ground engineering fire environment is established, and the foundation for the study of communication problems in complex fire environment is laid. |
