基于测震强震仪器健康状态数据的应用集成开发
|
摘要
首先介绍测震和强震仪器健康状态数据的集成方法,然后将方法应用于仪器健康状态分布式监视系统的服务器端设计,并通过综合应用Java EE、消息推送和WebGIS技术实现数据集成基础上的应用集成。系统具有功能实用、性能优异及界面友好的特点,在地震台网应用中有助于提高运维工作效率,同时可为测震强震台网业务系统的综合集成以及同类应用软件的开发提供典型示范。
The rapid development of the strong motion network in Hebei province has resulted in 48 new stations being added to enhance the seismic monitoring capacity.Each station is equipped with REFTEK 130-REN-3as the digitizer and SYSCOM MS2007+ as the accelerometer.Since the implementation of the project,a strong motion observation system has been established,which is relatively independent from the existing seismic network.It relies on heavy maintenance by engineers.Therefore,the problem of how to integrate the two systems and improve the efficiency of the network maintenance tasks has become urgent and is a key issue of concern.The integration of the systems requires a two-level approach,data integration as the foundation and application integration as the superstructure.In this paper,the application of instrument health data is introduced as an example.First,a model of health data integration is proposed.This model includes three layers:the data,middleware,and application layers.The data layer is the bottom layer and supplies health data to the upper layers from both the relational database and the Ethernet stream.The middleware layer is in the middle of the model;it shields the differences among the underlying data and provides a unified upward interface.It contains three components:message producer,message middleware,and mes-sage consumer.The message producer receives health data from the under layer,creates JMS messages,and sends them to the message middleware.The message consumer receives the JMS message from the message middleware,decodes the message into data,and sends them to the upper layer.The application layer is the top layer and through application integration it provides users with a unified graphic user interface.Second,the design and implementation of health data application integration into seismic and strong motion instruments is introduced.An application integration framework that comprehensively integrates several advanced technologies including Java EE,message pushing,and WebGIS is proposed.Software is introduced,which supports functions,including station map browsing,station health monitoring,and station database management.The software is developed under a Windows 7environment with MyEclipse 6.0as the IDE,Tomcat 6.0as the web server,ActiveMQ 5.5as the JMS broker,Geoserver 2.5as the WebGIS server,MySQL 5.1and PostgreSQL 8.4/PostGIS 1.5as the database server.It was found to be functional,practical,high-performance,and with a friendly-GUI.Its utility will help improve the efficiency of maintenance jobs at the seismic network.It is also a demonstration of comprehensive network integration and development for similar applications.
