江西测震台网运行故障统计分析

Statistical analysis of operation failure of Jiangxi seismic network

应用数理统计方法,系统分析了2015年以来连续5年江西测震台网25个台站运行中断的原因,总结归类为8大故障类型,揭示了台站供电和通讯网络是影响正常运行的主要因素,占比达92%以上;故障统计分析显示,高温酷暑和冰冻严寒是故障高危时段,每年约有8周时间。针对主要因素和高危时段,提出了相应的改进措施与工作建议,这对江西测震台网运行保障将起到积极作用。

Applying mathematical statistics method,this paper systematically analyzes the reasons for the interruption of the operation of 25 stations in Jiangxi seismic network for five consecutive years since 2015,and classifies them into 8 major faults types.It is found that the station power supply and communication network are the main factors affecting the normal operation,accounting for more than 92%.Statistical analysis of faults shows that high temperature,intense summer heat and freezing cold are high-risk periods of faults,which takes about 8 weeks per year.According to the main factors and high-risk period,corresponding improvement measures and working suggestions are put forward,which play a positive role in the operation guarantee of Jiangxi seismic network.
