极端条件下地铁应急通信保障的思考与对策

针对地铁发生重特大灾害事故造成公网瘫痪、电力中断等极端条件下，消防救援队伍应急通信保障存在的不足，提出了地铁应急通信保障的对策建议。探讨了现阶段运用有线+无线自组网基站混合组网，未来修订完善标准规范，在隧道内利用“光纤直放站+天线”的方式搭建隧道无线信号覆盖平台、建设专用区间电话等系统的方式，制定了解决方案，并模拟“断路断电断网”等极端条件，多次组织在不同城市的地铁站进行实地测试和全流程、全要素演练，验证了该解决方案的可行性。

Consideration and countermeasures of subway emergency communication guarantee under extreme conditions

In view of the shortcomings of the current emergency communication guarantee for fire rescue teams under extreme conditions such as public network paralysis and power interruption caused by major disasters and accidents in the subway, this paper puts forward countermeasures and suggestions for the emergency communication guarantee of the subway. At this stage, the hybrid networking of wired + wireless ad hoc network base stations is used, the standard specifications will be revised and improved in the future, the tunnel wireless signal coverage platform and special section telephone systems will be built in the tunnel by using the mode of "optical fiber repeater + antenna", the solutions are formulated, the extreme conditions such as "open circuit, power failure and network disconnection" are simulated, and the field tests and the whole process was organized in subway stations in different cities for many times. The feasibility of the solution is verified by the full element exercise.
