润扬长江大桥结构损伤预警系统的设计与实现

研究了润扬长江大桥结构损伤预警系统的功能、体系结构、数据库和应用软件的设计与实现方法.提出了结构损伤预警系统的两级架构设计和两阶段实现方法,以保证结构损伤预警的实时性和准确性.建议采用Client/Server和扩展Browser/Server两种系统模式相结合的形式将结构健康监测系统与损伤预警系统相互结合,并采用MIMOSA数据库规范进行损伤预警数据库的设计.针对基于扩展Browser/Server模式的损伤预警软件特点,提出分别采用ActiveX技术和ASP技术实现客户端和服务器端应用的软件设计方法,并在此基础上编制了润扬长江大桥结构损伤预警系统软件.

Design and realization of structural damage alarming system for Runyang Yangtse River Bridge

The design and realization method for structural damage alarming system of Runyang Yangtse River Bridge is discussed in detail with respect to system function,system framework,database and application software.The two-level framework design method and two-stage realization method for structural damage alarming system are put forward so as to guarantee the real-time performance and correctness.In order to connect the structural health monitoring and damage alarming system efficiently and effectively,the double system mode of Client/Server and extended Browser/Server are suggested and the design method for system database based on the international specification MIMOSA(machinery information management open system alliance) are also presented.The software design methods using the ActiveX and ASP(active server page) technology to realize the browser's and server's application are put forward according to the characteristics of extended Browser/Server system mode,on the basis of which the structural damage alarming system software is developed.
