摘　　要：煤矿井下通信的准确性与稳定性在紧急救援中至关重要。目前煤矿井下通信系统的定位精度不高,为解决这一问题,文中提出基于改进在线顺序超限学习机算法的煤矿紧急救援通信系统,并进行相应的仿真实验。结果显示,基于改进在线顺序超限学习机算法构建的煤矿紧急救援通信系统在实验1与实验2中的丢包率中位数分别为1.7×10^(-4)与1.4×10^(-4),明显低于其他对比算法构建的通信系统。在实验1与实验2中,改进在线顺序超限学习机算法、EfficientNet算法、在线顺序超限学习机算法、超限学习机算法的定位精度分别为96.8%、83.8%、76.4%、71.0%与95.9%、82.5%、75.8%、70.4%。可见改进OSELM算法在定位精度方面表现优越,基于该算法构建出的煤矿矿井紧急救援通信系统通信质量也更高。实验数据证明,该研究为煤矿紧急救援通信系统提供了一种高效且稳定的方法,为实际应用中的问题提供了有效的解决策略。The accuracy and stability of underground communication in coal mine is crucial in emergency rescue.At present,the positioning accuracy of underground communication system in coal mine is poor.Therefore,a coal mine emergency rescue communication system based on an improved online sequential extreme learning machine(OSELM)algorithm is proposed,and corresponding simulation experiments are conducted.The results show that the median packet loss rate of the coal mine emergency rescue communication system constructed on the basis of the improved OSELM algorithm in Experiment 1 and Experiment 2 is 1.7×10^(-4)and 1.4×10^(-4),respectively.Its median packet loss rate is significantly lower than those of the communication systems based on the other comparative algorithms.The positioning accuracy of the improved OSELM algorithm,EfficientNet algorithm,OSELM algorithm and ELM algorithm are 96.8%,83.8%,76.4%and 71.0%,respectively,in Experiment 1 and 95.9%,82.5%,75.8%and 70.4%,respectively,in Experiment 2.It can be seen that the improved OSELM algorithm is superior in terms of positioning accuracy,and the communication quality of the coal mine emergency rescue communication system based on this algorithm is also higher.Experimental data prove that the study provides an efficient and stable method for the coal mine emergency rescue communication system,and an effective solution strategy for practical problems.
