In order to create quantitative, objective and effective method maintaining civil infrastructures, this research aims to develop monitoring nodes which realize high-density measurements for them. A monitoring system, which combines a laser Doppler vibrometer with a Total Station for surveying, was applied to existing cable-stayed bridges. As a result, it was confirmed that the system made possible to realize remote and automated monitoring for bridges. Moreover, monitoring nodes using MEMS based technologies were developed. Their application test to vibration measurement of a bridge revealed that the nodes were possible to replace conventional measurement system.

为了创建维护民用基础设施的定量，客观有效的方法，该研究旨在开发监测节点，以实现为其实现高密度测量结果。将激光多普勒振动仪与用于测量的总站相结合的监测系统已应用于现有的电缆固定桥梁。结果，已经确认该系统有可能实现桥梁的远程和自动监视。此外，开发了使用基于MEMS的技术监测节点。他们对桥梁振动测量的应用测试表明，节点可以取代常规测量系统。
