摘要

目的

为解决消防救援和矿井检测等场景下强散射烟雾环境对可见光通信（VLC）造成的严重性能退化问题，文章研究了一种基于微型发光二极管（LED）烟雾环境VLC系统，突破传统光源强散射环境下的通信瓶颈，为第六代移动通信技术（6G）网络的应急场景以及通信与感知的一体化应用提供了技术方案。

方法

文章研制了基于InGaN/GaN多量子阱（MQWs）结构的微型LED发射器并建立了适用于烟雾VLC的Beer-Lambert信道模型，完成了衰减特性仿真验证；利用可控烟雾实验平台结合双透镜光路系统优化了光束聚焦，将光的利用效率提高到85%，同时对比分析了清晰环境下及不同烟雾浓度下的吸光度差异，搭建了烟雾VLC系统通信性能测试平台，并对系统通信性能进行了测量。

结果

微型LED发射器实现了3.39 MHz调制带宽，最大传输速率为25 Mbit/s，功耗为10~50 mW。在轻度烟雾条件下（1.4 g烟饼）信号功率衰减70%，系统能够保持稳定通信，眼图开口度大于50%；重度烟雾下（2.6 g烟饼）信号功率衰减85%，仍然能正常通信，收发稳定可靠，实现了通信及环境感知功能的融合。

结论

文章将微型LED应用于烟雾环境VLC中，重度烟雾条件下信号功率衰减85%时依然可实现稳定传输，解决了一直以来存在的光源不易于在强散射环境中稳定传输的问题。文章建立了Beer-Lambert信道模型，可为烟雾VLC系统的硬件设计和优化提供参考，实验表明，通过接收信号来定量地反演烟雾浓度，验证了微型LED在6G通感一体化领域的优势，可运用于消防救援和矿井监测等应急场景。

Abstract

Objective

To address the severe performance degradation caused by strongly scattering smoke environments on Visible Light Communication (VLC) in scenarios such as fire rescue and mine detection

this paper studies a smoke-environment VLC system based on micro-Light-Emitting Diode (LED). It aims to overcome the communication bottleneck of traditional light sources in strongly scattering environments. It also provide a technical solution for emergency scenarios in 6th Generation Mobile Communication Technology (6G) networks and integrated applications of communication and sensing.

Methods

A Micro-LED transmitter based on an InGaN/GaN Multiple Quantum Well (MQWs) structure was developed. A Beer-Lambert channel model suitable for smoke VLC was established

and its attenuation characteristics were verified through simulation. Using a controllable smoke experimental platform combined with a dual-lens optical system to optimize beam focusing

the optical utilization efficiency was improved to 85%. Simultaneously

the absorbance differences under clear conditions and different smoke concentrations were compared and analyzed. A communication performance test platform for the smoke VLC system was built

and its performance was measured.

Results

The Micro-LED transmitter achieved a 3.39 MHz modulation bandwidth

a maximum transmission rate of 25 Mbit/s

and a power consumption of 10~50 mW. Under light smoke conditions (1.4 g smoke cake)

with a 70% signal power attenuation

the system maintained stable communication with an eye diagram opening greater than 50%. Under heavy smoke conditions (2.6 g smoke cake)

with an 85% signal power attenuation

stable and reliable communication was still achieved

realizing the integration of communication and environmental sensing functions.

Conclusion

This paper pioneers the application of Micro-LEDs in visible light communication within smoke environments. Under heavy smoke conditions

stable transmission is still achievable even with an 85% signal power attenuation

solving the long-standing problem of light sources struggling to maintain stable transmission in strongly scattering environments. The established Beer-Lambert channel model provides a reference for the hardware design and optimization of smoke VLC systems. The experiments demonstrate that smoke concentration can be quantitatively inferred by analyzing received signals

verifying the advantages of Micro-LEDs in the field of 6G integrated sensing and communication. This technology can be applied to emergency scenarios such as fire rescue and mine monitoring.
