5G中分布式云技术方案的应用

集装箱式边缘数据中心是5G通信网络中的一类重要节点，准确评价其在不同强度地震作用下的功能水平是5G通信网络震后功能评价的基础。该文以一个典型集装箱式边缘数据中心为研究对象，提出了该类数据中心震后功能的概率评价方法。详细分析了典型数据中心5个子系统的基本部件构成和各基本部件间的功能逻辑关系，建立了子系统的故障树模型和数据中心的状态树模型；通过数值模拟和文献调研，给出了数据中心各基本部件的地震易损性参数；将状态树和蒙特卡洛模拟相结合，计算出了典型数据中心的地震功能易损性曲线和参数。研究表明：空调内机、蓄电池柜和空调外机是集装箱式边缘数据中心的薄弱环节，改善这些薄弱环节可显著提升集装箱式边缘数据中心震后功能水平。

Application of distributed cloud technology solution in 5G

The containerized edge data center (CEDC) is one of the critical components of the 5G communication network. Accurate assessment of its functionality level under earthquakes with various intensities is the foundation of post-earthquake functionality assessment of the communication network. Taking a typical CEDC as the research object, a probabilistic-based method is developed to evaluate its post-earthquake functionality. The critical components of five subsystems of the CEDC were recognized and the functional logic relationship between these components were analyzed. Then the fault tree model of each subsystem and the state tree model of CEDC were established. The seismic fragility parameters of each critical component were given based on previous literature or supplemental analyses. Seismic functional fragility curves and parameters of CEDC were calculated by combining the state trees with Monte Carlo simulation. The results indicate that the indoor and outdoor units of air conditioning, and battery cabinet are the most vulnerable parts of CEDC. Enhancement of these parts can significantly improve the post-earthquake functionality level of CEDC.
