摘　　要：随着我国建造行业逐步向智能建造转型升级,高层结构地震响应和健康监测技术所涉及的传感器数目、待处理的数据量以及系统的复杂性都在不断增加。针对高层建筑结构地震响应和健康智能化监测需求,将物联网LoRa扩频通信技术引入到高层结构智能化监测系统中,设计实现基于LoRa的高层结构地震响应和健康监测软硬件平台方案。该系统由多个LoRa终端节点、LoRa网关、OneNET服务器和用户4个部分组成,监测数据通过LoRa网络传输,LoRa网关通过ESP8266模块接入云平台,将采集到的监测数据形成可视化监测界面。经测试,在城市空旷环境下该系统3 km内的丢包率小于8%,可实现高层结构地震响应和健康监测数据远距离、低功耗的可靠传输,帮助用户进行地震作用下振动反应资料的累积、建筑结构的状态评估和设施管理。As the building industry in China gradually transforms and upgrades to intelligent construction,the number of sensors involved in the seismic response and health monitoring technology of high-rise structures,the amount of data to be processed,and the complexity of the system are increasing.In this paper,to meet the intelligent monitoring demand of seismic response and health of high-rise buildings,LoRa spread spectrum communication technology based on the Internet of Things was introduced,and the software and hardware platform scheme of high-rise buildings'seismic response and health monitoring based on LoRa was designed and implemented.The system consisted of multiple LoRa terminal nodes,LoRa gateway,OneNET server,and users.The monitoring data were transmitted through the LoRa network,and the LoRa gateway was connected to the cloud platform through the ESP8266 module to form a visual monitoring interface for the collected monitoring data.The test results show that the packet loss rate of the system within 3 km in an urban open environment is less than 8%.The system can realize the long-distance,low-power,and reliable wireless transmission of seismic response and health monitoring data of high-rise structures,and help users accumulate vibration response data under earthquake,evaluate the state of building structures and manage facilities.
