采用标准差分析、描述性统计等数理统计方法,对2019—2023年山东测震台网126个测震台站的历史故障数据进行汇总分析。将台站故障类型分为通讯故障、供电故障、专业设备故障、人为因素影响4大故障类型,统计近5年每种故障类型的故障次数和时长,结果可知,通讯和供电故障在总故障次数中占比高达77%。通过对月故障次数的统计,可知7—9月的故障发生频次明显高于其他月份,判断台站主要受雨季和高温的影响。通过对以上分析结果提出针对性的措施建议,为台网运行率和稳定性的进一步提升奠定基础。
Statistical methods such as standard deviation analysis and descriptive statistics are used to summarize and analyze the historical fault data of 126 seismic stations in Shandong Seismic Station Network from 2019 to 2023. The station fault types are classified into four major types, namely, communication faults, power supply faults, professional equipment faults, and human factors impacts. By calculating the number and duration of each type of fault in the past five years, the results show that communication and power supply faults account for as much as 77% of the total number of faults. Through the statistics of the number of monthly failures, it can be seen that the frequency of failures in July-September is significantly higher than other months, what indicatethat the station is mainly affected by the rainy season and high temperatures. Based on the above analysis results, targeted measures and suggestions are proposed to lay the foundation for further improvementof the operation rate and stability.
