摘　　要：山西地震台网运维智能管理系统通过多线程ping台站IP地址实现链路监控,通过连接JOPENS系统的流服务器监控实时数据流接收状态,自动生成故障日志,维护人员填报日志后,系统自动判定是否有地震计或数据采集器的更换,根据新的仪器类型和序列号查找对应的仪器响应,自动将JOPENS系统中有关台站参数进行更新;同时,系统根据获取到的台站连续波形,按照数据预处理、加速度功率谱密度PSD估算、加速度功率谱概率密度PDF估算的步骤实现对台站噪声的质量监控。The intelligent management system for the operation and maintenance of the Shanxi Seismic Station Network has enabled link monitoring through the use of multi-thread ping to monitor the IP addresses of the stations.Additionally,and the system continuously monitors the reception status of real-time data streams using a flow server connected to the JOPENS system,and automatically generates fault logs when necessary.Once the maintenance personnel have filled in the log,the system can automatically determines whether a seismometer or data collector replacement is necessary,and identify the corresponding instrument response based on the new instrument type and serial number.The system then updates the relevant station parameters in the JOPENS system accordingly.In order to ensure the quality of the station noise,the system acquires continuous waveform data from the station and applies a series of steps,including data preprocessing,acceleration power spectral density(PSD)estimation,and acceleration power spectrum probability density(PDF)estimation,to implement station noise quality monitoring.
