大型桥梁健康无线监测系统

针对传统桥梁健康监测采用有线方式进行数据通信的缺点,提出基于GPRS(通用分组无线业务)网络的大型桥梁无线监测系统,介绍了系统的工作原理,采用32位ARM微处理器S3C44B0X及GPRS模块GR47,设计了具有GPRS功能的桥梁健康监测器,给出了桥梁健康监测器应用软件的实现流程,同时描述了监控中心的GPRS通信服务器软件的实现,并从荷载环境监测、几何监测、结构静动力监测、实时预报警、健康状态评估、系统管理及数据库服务器设置7个方面阐述了监控软件功能模块。实际测试结果表明,该系统具有实时性好、可靠性高等特点。

Wireless monitoring system of long-span bridge health

Aiming at the limitation of traditional bridge health monitoring system with cable,a new wireless monitoring system of long-span bridge based on GPRS is presented.The principle of system is introduced.A bridge health monitor which adopting 32-bit microprocessor S3C44B0X and GPRS module GR47 is designed and its flowchart is given also.The realization of GRPS data communication service is described.And the function module of monitor software are also analyzed from seven aspects including environmental loading monitoring,geometrical monitoring,static and dynamic force of structure monitoring,run-time alarm,health statement assessment,system management,configure of database server.The result of test shows that this system has characters of good real-time and high reliability.5 figs,9 refs.
