天津地铁控制中心无线话务量的估算

Estimation of Wireless Traffic Value for Control Center of Tianjin Subway

地铁控制中心是地铁运营管理的核心。特别是在设备故障和突发事件直接影响地铁正常运营的情况下,控制中心调度员要及时、灵活地进行调度管理,要保障地铁安全、高效运营。所以,控制中心的通信质量在地铁运营过程中起着十分重要的作用。根据天津地铁1号线控制中心目前的无线通信现状,以及考虑1、2、3号线控制中心合设,必将增加通信话务量,为此提出了增加一套基站的解决方案。根据对将来话务量的估算,结果表明该方案是可行的。

Subway control center is the core of subway op- eration management, especially when equipment failure and unexpected events directly affect subway normal opera- tion. Central control operator needs to manage scheduling timely and flexibly to ensure safe operation and efficient transport. Therefore, communication quality of control center plays a very important role in subway operation. Ac- cording to wireless communication situation of Line 1 in Tianjin subway control center, the integration of control centers of Line 1, Line 2 and Line 3 will definitely increase the communication traffic volume. Based on this concern and estimation of future communication traffic, adding one base station will be a better solution.
