The followings are studied1) Monitoring systems that utilize the motion of vehicles and trains, namely VIMS (vehicle intelligent monitoring system) and TIMS (train intelligent monitoring system are studied from theoretical as well as practical points of view.2) Seismic responses data from densely installed sensors in Yokohama Bay Bridge from 1989 to 2005 were analysed using the MIMD (multiple input and multiple output) system identification method and it is found that existence of the modes not dealt with the design model is identified; the end ling behaved as a rigid connection.3) Middlewares of the wireless sensing system using imote2 are developed, I,e., synchronized sensing, data transmitting loss, decentralized data processing for the real time emergency signal processing.

研究了以下内容：1）利用车辆和列车运动的监控系统，即VIMS（车辆智能监控系统）和TIMS利用MIMD软件对横滨海湾大桥1989 - 2005年密集安装的传感器的地震反应数据进行了分析（多输入多输出）系统辨识方法，发现设计模型中未处理的模态的存在性被辨识出来，端部表现为刚性连接。3）开发了基于imote 2的无线传感系统中间件，同步感知、数据传输丢失、分散数据处理，实现真实的实时应急信号处理。
