摘　　要：为满足杭州亚运会主体育场大跨度空间结构的健康监测与分析需求,基于这类建筑的结构特征与服役环境,定制了一种多参数、模块化的无线传感网络系统,研发了智能可拓展的树形组网策略与时间同步采集机制,实现了基于物联网平台的远程系统监控。研究结果表明:基于物联网平台,可实现结构的远程监控与结构响应分析,可实时反映结构的性能状态,系统的长期稳定工作验证了其稳定性和耐久性;体育场各类参数的监测数据不仅反映了结构关键构件在施工过程中的内力主要受卸载与环境温度影响较明显的变化规律,也分析了运营期结构的风载、振动、温度场等环境荷载处于设计范围之内的基本特征,以及结构长期应力较为稳定,受温度变化影响较大的主要规律,可用于体育场结构的施工、运营与管理。In order to satisfy the health monitoring and analysis needs of the large-span spatial structure of the main stadium of the Hangzhou Asian Games,firstly,based on the structural characteristics and service environment of these kind of buildings,a multi-parameter,modular wireless sensor network system was customized,and an intelligent and expandable tree-type networking strategy anda time synchronization collection mechanism were developed to satisfy the hardware technical requirements of large-span spatial structures.Secondly,based on the Internet platform,the remote monitoring and structural response analysis of the structure were realized to reflect the performance status of the structure in real time,and the long-term stable work of the system verified its stability and durability.Finally,the monitoring data of various parameters of the stadium not only reflected the internal force change of key components of the structure during the construction process,but also the basic characteristics of environmental loads such as wind load,vibration and temperature field of the structure during the operation period.The monitoring data also indicate that the long-term stress of the structure is relatively stable and is mainly affected by the change of temperature,which provides scientific guidance for the construction,operation and management of the stadium structure.
