摘要

分析了煤矿工作面可见光通信系统模型, 设计了两种工作面通信空间发光二极管(LED)光源分布优化方法, 可分别实现每个LED光源在空间顶部的二维位置的优化, 以及每个LED光源二维位置及其功率分配权值的协同优化。应用烟花算法, 设置接收平面的信噪比(SNR)因子作为群体优化算法的目标函数, 并作为衡量接收平面信号均匀性的指标。研究结果表明, 两种优化方法得到的接收平面信号SNR因子比等功率均匀阵列光源分布的SNR因子分别降低了16.6%和24.6%, 明显改善了接收信号SNR波动, 提高了信号均匀性, 保证了不同用户之间的同等通信质量。

Abstract

The system model of visible light communication in coal mine working face is analyzed. Two optimization methods of LED light source distribution in coal mine working face are designed. One is be used to optimize the two-dimensional position of each LED light source on the top of working space, and the other is used to co-optimize the two-dimensional position and its power weight of each LED light source. The fireworks algorithm is adopted and the signal-to-noise ratio (SNR) factor of the receiving plane is set as the target function of the group optimization algorithm as well as the indicator for evaluating the uniformity of signals in the receiving plane. The research results show that after optimization with these two methods, the SNR factors of signals in the receiving plane are reduced by 16.6% and 24.6%, respectively, compared with that under the uniform array distribution of LED light sources with equal powers. The SNR fluctuation is significantly improved, the optical signal uniformity is also improved, and thus the same communication quality among different users is ensured.
