陕西地震烈度速报与预警系统一般站运行对比分析

Comparative analysis on the operation of general stations of Shaanxi earthquake intensity quick report and early warning system

  • 摘要: 陕西地震烈度速报与预警系统共1000个一般站,包含国家项目485个和省级项目515个,均在2021年9月底完成了台站基础建设及仪器设备安装,并将数据传回陕西地震预警中心。试运行期间,基本符合中国地震局一般站试运行的技术要求。鉴于两个项目的组网方式、设备选型、安装场地不同,本文统计2021年11月—2022年2月共4个月项目运行率、数据延迟等数据,针对两个项目一般站运行的组网方式、运行率、通讯情况进行对比分析发现,国家一般站较之省级一般站运行率稳定但延时较大,台站密集区域延时会增大,国家和省级一般站均不能满足小于等于2 s的通讯延时。考虑到在未来的地震监测效能提升工程中,可能将一般站加密部署到省内全部乡镇街道。本文工作可为未来一般站建设组网模式等方面,形成具有一定参考价值的运行数据支撑,针对通讯延时、设备安装等方面提供一定建议。

     

    Abstract: Shaanxi earthquake intensity quick report and early warning system has a total of 1000 general stations, including 485 national projects and 515 provincial projects. The station infrastructure construction and instrument equipment installation were completed at the end of September 2021, and the data were sent back to Shaanxi Earthquake Early Warning Center. During the trial operation period, it basically met the technical requirements of the trial operation of general stations of China Earthquake Administration. In view of the different networking modes, equipment selection and installation sites of the two projects, this paper counted the project operation rate, data delay and other data for a total of four months from November 2021 to February 2022. Based on the comparative analysis of the networking modes, operation rate and communication conditions of the general stations of the two projects, it is found that the operation rate of the national general stations is more stable than the provincial general stations, but the delay time is larger. The delay time in the dense area of stations increased. The national and provincial general stations cannot meet the communication delay of less than or equal to 2 s. Considering that in the future earthquake monitoring efficiency improvement project, general stations may be encrypted and deployed to all township streets in the province. This work can form a certain reference value of operation data supporting for the construction of networking mode of general stations in the future, and give some suggestions for communication delay, equipment installation, etc.
