摘要:

针对天津市测震台网数字化资料数量庞大、种类繁多以及各台网之间数据交换困难,无法与台站参数准确结合的问题,利用PHP语言研制测震台网综合管理系统,实现数据共享功能,通过liss数据流的二次开发,实现大震后地震事件的快速产出,满足了地震预报、新参数计算的需要;同时将台站设备参数与数据相结合,保证了数据使用的准确。该系统的使用在一定程度上将提高测震台网工作效率和数字观测资料的使用率。

Abstract:

Owing to the abundant and various digital data within the Tianjin Seismic Station Network, difficulties occur in data exchanges between various networks when stations parameters cannot be accurately combined.The development of an integrated management system realizes data-sharing through the secondary development of liss data flow and through the fast output of large earthquake seismic events. There was need for new parameter calculations that simultaneously combined the station equipment parameters and data together,to ensure the accurate use of the data.The use of this new system will improve the efficiency of the seismic station network and the utilization rate of the observational material. The Tianjin Seismic Station Network released an integrated management system based on VB.Net in 2011.The system realized link monitoring and journal management as well as regulating the daily work and raising the monitoring capability of the link.The growth of digital observation data has caused the problem of how to provide data services and how to help if the need for a seismic trace becomes urgent. Thus,we developed a new system that utilizes the advantages of PHP and MySQL.It has the following functionalities.The administrator can add a user name,change a password,and grant user permissions. Normal users can search and download seismic events.As earthquake forecasters depend on the fast output of data during a seismic event,this new system raised the efficiency of data output.Simultaneously, the new system rapidly reports and determines the earthquake intensity,publishing both messages together; this message includes the result charts and vectorgraph.Thus,different offices can launch rescue workers and provide field monitoring on the basis of the produced message.The functionality of passing parameters in the system was added to prevent discrepancies between data and parameters.At the same time,online detection was added to draw curves of the damping changes and to produce exact figures.
