Post-earthquake functional state assessment of communication
A method to evaluate the post-earthquake functionality of communication base stations using Bayesian network is developed.
A method to evaluate the post-earthquake functionality of communication base stations using Bayesian network is developed. The dependence between the equipment and its hosting building structure, and the impact of power outages are considered. The method is validated using seismic damage data from the Ludian Earthquake.
Therefore, this transformation process provides a more accurate assessment of the post-earthquake functional status of base stations and serves as an important basis for subsequent operation and maintenance decisions. 3.2.1. Construction of Fault Tree Model
In the chaotic aftermath of a disaster, communication networks are often challenged by increased usage and/or damage to their base stations. This situation often results in network congestion and subsequent failures of communication systems when reliable communication is most needed.
An indoor base station comprises a communication room accommodating various communication equipment and a communication tower responsible for transmitting and receiving information. The communication room is equipped with wireless communication devices, transmission equipment, power supply equipment, air conditioning, and cable routing racks.
