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。
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.
