山地城市超高层结构健康监测系统建设与应用

Construction and application of super highrise structural health monitoring system in mountainous cities

针对山地城市超高层结构健康监测中存在的传感器类型多,通信组网复杂,多源数据处理流程各异等问题,本文基于前端感知层、采集传输层、云服务平台和用户交互子系统的架构,遵循可靠、经济、开放的原则,构建了山地城市超高层结构健康监测系统。该系统通过前端多传感器感知技术、多类型数据传输网络、预警动态评估策略和信息实时发布机制,实现了对超高层建筑结构响应与环境荷载的实时监测,并通过在重庆市某超高层建筑第三方监测项目中的应用,验证了该系统的可行性。

For the problems such as multiple sensor types,complex communication network and different multisource data processing flows of super highrise structural health monitoring in mountainous cities,this paper proposes to build a health monitoring system for super highrise buildings in mountainous cities by using an architecture based on frontend sensing layer,acquisition and transmission layer,cloud service platform and user interaction subsystem,and by following the principles of reliability,economy and openness.The system can realize realtime monitoring of structural response and environmental load of super highrise buildings through frontend multisensor sensing technology,multitype data transmis⁃sion network,early warning dynamic evaluation strategy and realtime information release mechanism.The feasibility of the system is demonstrated by using it in a thirdparty monitoring project of a super highrise building in Chongqing City.
