无线通信定位一体化进展及其在煤矿井下应用分析

Development of integrated localization and wireless communication and its application in the underground coal mine

  • 摘要: 无线通信定位一体化(ILWC)是一种基于硬件资源及软件信息共享以实现定位与通信功能协同的新型信息技术。通过简述无线通信技术和定位技术的研究进展,揭示了ILWC技术是无线通信系统承载业务拓展的必然结果。给出了不同研究对于ILWC技术的定义和内涵,明确了ILWC核心思想为“硬件集成,软件共享”,按照设备复用和深度融合2个阶段综述了ILWC技术的研究进展。结合煤矿井下场景的特殊性,提出了煤矿井下ILWC概念:基于时间、空间、频谱、计算等资源共享,具有场景自动感知和资源动态自适应分配机制的通信功能和定位功能融合技术。对煤矿井下ILWC在大巷、中央变电所、井底车场、采煤工作面等场景的适应性进行了讨论,指出井下ILWC面临的挑战是煤矿井下无线信道复杂性、基站部署不均衡性、井下复杂场景精准判别。

     

    Abstract: Integrated localization and wireless communication(ILWC) is a new information technology based on hardware resources and software information sharing to realize the coordination of location and communication functions. This paper briefly introduces the research progress of wireless communication technology and localization technology, and reveals that ILWC technology is the inevitable result of the bearer services expansion of wireless communication system. This study summarizes the definition and connotation of ILWC technology in different research. The core idea of ILWC is defined as "hardware integration and software sharing". The research progress of ILWC technology is summarized according to the two stages of equipment reuse and deep fusion. Combined with the particularity of the scene of the coal mine, the concept of ILWC in the coal mine is put forward. Based on the sharing of time, space, spectrum, computing and other resources, the technology is the fusion technology of communication function and localization function with an automatic scene perception and dynamic and adaptive resource allocation mechanism. The adaptability of underground ILWC in roadway, central substation, underground parking lot, coal working face and other scenes is discussed. It is pointed out that the challenges faced by underground ILWC are the complexity of underground wireless channel, unbalanced deployment of base stations and precise recognition of complex underground scene.
