基于Java的桥梁强震动实时监测及警报系统开发与应用

摘要

Strong motion monitoring arrays have been built on Queshi Bridge in Shantou, Jiujiang Bridge in Fokai highway, Huangpu Bridge over Zhujiang River and Humen Bridge in Dongguan. The amount of structural real-time vibration data of long-span bridges collected by the strong motion monitoring arrays are huge, and the timeliness requirement of earthquake, collision and other events is high. Therefore, it is necessary to establish a rapid response monitoring data processing and alarm system. This paper develops the strong motion real-time monitoring and alarm system based on Client/Server ( C/S) mode for bridges by using Java language and combining with Socket and multi-threading technology based on JOPENS. The system comprises configuration module, data acquisition module, data storage module, monitoring module, data browsing module, alarm module and data analysis module. The system can be installed across different platform, and the interface is simple and easy to operate. The system has been running steadily for 2 to 6 years on several bridges, and it can be applied to the strong motion monitoring and alerts of other major engineering structures.%本文使用Java语言，在测震台网《数据采集与常规处理》区域版(JOPENS)的基础上结合Socket、多线程等技术，开发出基于Client/Server (C/S)模式的桥梁强震动实时监测及警报系统，系统包括配置模块、数据采集模块、数据存储模块、监测模块、数据浏览模块、警报模块和数据分析模块，可跨平台安装。该系统已在多座大桥上稳定运行，可将其推广到其他重大工程结构的强震动监测及事件警报。
