基于故障树法的广播电视信号传输安全风险评价

Risk assessment of radio and television signal transmission safety based on FTA

利用故障树法对广播电视信号传输安全进行了风险分析评价。在系统技术分解的基础上建立了故障树模型,并对风险因素进行了风险识别;通过计算故障树的最小割集和结构重要度,对风险因素进行了定性和定量分析,最终得到了相应的风险评价结果。研究成果可作为广播电视信号传输安全风险管理的决策支撑,为广播电视台的安全播出工作提供坚实保障。

In this paper FTA(Fault Tree Analysis)was used to conduct risk analysis and evaluation on the safety of radio and television signal transmission.A fault tree model was established based on the technical decomposition of the system,and the risk factors were identified;by calculating the minimum cut set and structural importance of the fault tree,the risk factors were qualitatively and quantitatively analyzed,and the corresponding risk assessment results were obtained.The research results can be used as decision-making support for safety risk management of radio and television signal transmission,and provide a solid guarantee for the safe broadcasting work of radio and television stations.
