摘要
采煤工作面无线传感器网络有助于采煤工作面环境监测与采矿设备的自动化控制,而无线通信是影响采煤工作面无线传感器网络工作性能的关键因素。本文首先提出采煤工作面无线传感器网络系统结构图。其次分析采煤工作面煤岩层结构、机器噪声等因素对井下无线通信损耗的影响,建立了采煤工作面的无线通信信道模型。最后对模型进行仿真分析,并与实测数据相比较,结果表明,所建立的无线通信信道模型与实测数据有较好的匹配,为构建采煤工作面无线传感器网络奠定了基础。
Coal face wireless sensor network is helpful in environmental monitoring and automatic control of mining equipment,and wireless communication is a key factor affecting the coal face working performance of wireless sensor networks.This paper firstly proposed coal face wireless sensor network system structure,then analyzed communication loss factors in underground wireless such as coal-rock structure,machine noise and other factors,built coal face wireless communication channel model.Finally made model simulation analysis,and compared with measured data,results show that the model matches measured data well,which built foundation for coal face wireless sensor network.
