摘要:

通过Matlab软件平台开发了相应的使用程序,能充分调用不同厂家提供的各式解码程序以及发挥Matlab优秀的界面操作与做图功能,解决了天津市强震动台网强震数据解码过程中断、数据批量成图及数据通道选择、峰值提取及仪器烈度转换、烈度结果发布等基础技术问题,使速报速度由几个小时缩短到几分钟。介绍了其中的技术难点并用实例说明Matlab在天津市强震动台网烈度速报中应用的可行性。

Abstract:

In the intensity rapid report work of Tianjin strong motion network,utilizing the Matlab software,a series of relative procedures are developed,which can effectively execute the decode EXE file provided by different equipment producers and make best use of the excellent function of Matlab GUI-operation and imaging.These procedures overcome some basic technical difficulties including the interruption of data decoding,bulk of imaging,selecting of data,extracting of the max values and transferring them to equipment intensities,intensity rapid report etc.The time of rapid equipment intensity in the Tianjin network reduces apparently to a few minutes in comparison with some hours before.Some skills of overcoming the above difficulties and the application that can support the feasibility of using Matlab to deal with intensity rapid report in Tianjin are introduced.
