Abstract：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.
