数据传输故障下EDAS-24GN型数据采集器的数据获取与格式转换
Data acquisition and format conversion of the EDAS-24GN data logger under data transmission failures
【摘要】 在测震台站观测硐室地震数据采集器至办公机房的数据传输环节中,若存在网络故障、断缆、停电、计算机宕机、软件故障等突发事件,易造成测震数据断记,影响数据可用性。以测震台站广泛使用的EDAS-24GN型地震数据采集器为例,简要介绍了数据传输故障时的数据获取方式及格式转换,即:通过FTP远程登录或现场直连方式,从采集器中下载指定时段的.dat格式原始数据;利用EDAS_VIEW软件,将下载的数据转换为中国地震台网中心要求的地震数据交换标准格式(SEED),并针对合并文件后出现的台网标识异常问题,采用UltraEdit软件对文件相应头段内容进行替换,实现原台网标识的精准恢复。北京地震台的应用实例表明,采用该方法可快速恢复故障时段的观测数据,提高测震台站的数据连续性和运行效率。
【Abstract】 In the data transmission link from the seismic data logger in the observation chamber to the computer office of a seismological station, sudden incidents such as network failures, cable breaks, power outages, computer crashes, or software malfunctions are likely to cause missing seismic data records and affect data availability. Taking the widely used EDAS-24 GN seismic data logger as an example, this paper briefly introduces the data retrieval method and format conversion during data transmission failures. Specifically, the original data in ‘.dat’ format of a specified period is downloaded from the logger via FTP remote login or direct on-site connection. Using the EDAS_VIEW software, the downloaded data is converted into the SEED format, required by the China Earthquake Networks Center. To address the abnormal network identification issue after file merging, the UltraEdit software is used to replace the corresponding header content to restore the original network identifiers. Application examples from the Beijing Seismological Station demonstrate that this method can quickly restore observation data during failure period, thereby improving the data continuity and operational efficiency of seismological stations.
