超宽带无线通信技术在煤矿井下的应用探讨

Probe on UWB Wireless Communication Technology for Coal Mine Underground

针对目前煤矿井下无线通信的状况,提出了将超宽带(UWB)无线通信技术应用于煤矿井下的设想。介绍了超宽带无线通信技术的概念、特点及系统组成,探讨了超宽带无线技术用于煤矿井下通信时,窄脉冲波形的确定、系统方案的选择及其应用的场合等问题。最后指出超宽带信号在矿井巷道中的传播特性研究对于设计煤矿井下UWB无线通信系统是至关重要的一步。

According to the analysis of the status of wireless communication for coal mine underground, a suggestion of using UWB wireless communication system for coal mine underground communication was proposed. Some new concepts, characteristics and a system structure of UWB wireless communication technology were introduced, and several problems about narrow pulse waveform, the system scheme and application occasion of underground UWB system were discussed. Finally it was pointed out that the research of the propagation characteristic of UWB in coal mine tunnel is the most important step for adopting UWB wireless communication system in coal mine underground.
