摘要

上盖动车所在采用多密度结构柱的环境下，无线对讲人员只能近距离通话，无法在设施区间内大范围移动的同时进行无线对讲。针对上盖动车所无线对讲系统的需求，优化了现有首个上盖动车所设备，首次在铁路通信中提出了数字/模拟兼容的无线对讲系统中继方案，同时实现了系统自激干扰消除，创新设计了一套试用于铁路动车所的系统设备，使该系统满足超大范围内全区域人员对讲机直接通话的需求。通过现场测试验证了该套系统的设计水平和应用效果，在满足业务需求的情况下，系统误码率降低到1%以下。为类似环境如客货运车站、物流园区、港口等场景下的无线通信系统设计提供了参考。

Abstract

In environments where the overhead covered depots for electric trains employs multi-density structural columns

wireless intercom personnel can only communicate at close range

making it impossible to conduct wireless intercom while moving within a large area of the facility. In response to the requirements of the wireless intercom system for overhead covered depots for electric trains

the existing equipment of first-ever Depot for Electric Trains was optimized

proposing for the first time in railway communications a relay solution for a digital/analog compatible wireless intercom system. Simultaneously

self-excited interference elimination was realized and a set of system equipment suitable for railway depots for electric trains was innovated

enabling the system to meet the demand for direct intercom communication among personnel across the entire ultra-large area. Field tests verify the design level and application effectiveness of this system

reducing the system's bit error rate to below 1% while satisfying business needs. This provides references for the design of wireless communication systems in similar environments

such as passenger and freight train stations

logistics parks

ports

and other scenarios.
