摘要
专用无线通信是城市轨道交通内部运营管理和业务的重要保证。如何在保证无线通信质量的前提下,合理地计算无线通信系统场强覆盖,是研究无线通信其中的一个重要方面,只有采取了合理的无线覆盖方式,才能够避免无线通信系统的无序、重复建设和无线资源的浪费。通过对宁波轨道交通1号线隧道、站台、站厅的建筑形式分析,确立典型隧道区间、站台、站厅的电波传播路径、覆盖模型以及路径损耗。在此基础之上,得出满足无线覆盖条件下的关键点电平,为今后地下车站和区间无线覆盖的建设提供参考依据。
Wireless communication is an important guarantee for internal operation management as well as business of urban rail transit. It is an important research area of wireless communication about how to calculate the field coverage of wireless communication system reasonably in the condition of ensuring the quality of wireless communications at the same time. Only by adopting reasonable methods for wireless coverage can we avoid chaos of the wireless communication system, repetitive construction and waste of resources. Through the analysis of the architecture form of stations, tunnels, platforms as well as the stations＇ hall of Ningbo Metro Line 1, the wave path in typical interval tunnel platform and the station hall, its coverage model and path loss were established. On this basis, the key point level that meets the condition of wireless coverage could be obtained. The research could provide a guidance for future construction of underground stations and their interval coverage.
