从功能划分的角度,将移动通信系统分为基站子系统、传输子系统与供电子系统三部分,对其关联结构、运行功能进行系统分析;结合汶川、鲁甸等历史地震中通信系统典型破坏案例,对移动通信基础设施系统的典型震害破坏形式与机理进行了总结分析;基于故障树模型,分析地震灾害下移动通信基站退服的多层级、多类型的故障原因,提出了地震破坏造成通信基站退服故障的系统分析模式.
From the perspective of functional division, the mobile communication system is divided into three parts: base station subsystem, transmission subsystem and power supply subsystem, and its related structure and operation function are analyzed systematically. Combined with the typical failure of communication system in historical earthquakes such as Wenchuan and Ludian Case, this paper summarizes the typical forms and mechanisms of damage to the mobile communication infrastructure system. Based on the fault tree model, it analyzes the multi-level and multi-types of failure reasons of the mobile communication base station under the earthquake disaster, System Analysis Mode of Communication Base Station Failure Service.
