【摘要】：自然災(zāi)害造成的災(zāi)難是觸目驚心的,對房屋建筑和橋梁結(jié)構(gòu)都產(chǎn)生了巨大的威脅,造成了巨大的經(jīng)濟(jì)損失,并威脅著人類的生命安全。但是自然災(zāi)害是無法避免的,所以為了減少經(jīng)濟(jì)損失和保護(hù)人類的生命安全,需要建立完善的結(jié)構(gòu)健康監(jiān)測系統(tǒng),對結(jié)構(gòu)性能進(jìn)行健康監(jiān)測,及時發(fā)現(xiàn)結(jié)構(gòu)損傷,對可能出現(xiàn)的災(zāi)害進(jìn)行預(yù)測,并評估結(jié)構(gòu)安全性。 目前,結(jié)構(gòu)健康監(jiān)測系統(tǒng)已取得了比較完善的發(fā)展,在土木工程結(jié)構(gòu),尤其是橋梁結(jié)構(gòu)中得到了飛速的發(fā)展,但目前只在一些特定大型結(jié)構(gòu)上使用,并沒有面向大眾的監(jiān)測方式,為了更加方便快速的實現(xiàn)結(jié)構(gòu)健康監(jiān)測,本文提出云監(jiān)測的概念,并在此基礎(chǔ)上進(jìn)行了一系列的探索研究。主要工作如下： 1.提出面向土木工程結(jié)構(gòu)云監(jiān)測的概念,并進(jìn)行了詳細(xì)闡述。選擇智能手機(jī)作為云監(jiān)測終端和控制中心,以此初步實現(xiàn)云監(jiān)測的基本功能。結(jié)合當(dāng)今智能手機(jī)的發(fā)展?fàn)顩r以及常用手機(jī)的參數(shù)以及其內(nèi)置傳感器的傳感性能,論證了智能手機(jī)作為云監(jiān)測智能終端的可行性。 2.在iphone4s的IOS平臺上開發(fā)了一套云監(jiān)測軟件系統(tǒng),包括數(shù)據(jù)采集程序、指令控制程序以及網(wǎng)絡(luò)存儲程序。實現(xiàn)對GPS信息、加速度、傾角等監(jiān)測信息的監(jiān)測。 3.將該云監(jiān)測系統(tǒng)應(yīng)用到橋梁索力監(jiān)測中,分別在實驗室的索模型、大連華錄橋、哈爾濱四方臺大橋上進(jìn)行了實驗驗證,采用智能手機(jī)加速度采集系統(tǒng)與壓電式加速度傳感器和力平衡式加速度傳感器的結(jié)果進(jìn)行對比分析,結(jié)果表明本論文研發(fā)的移動智能終端能夠準(zhǔn)確測量拉索索力。 4.為了拓展移動智能終端的可監(jiān)測參數(shù),以及針對目前位移監(jiān)測困難之現(xiàn)狀。研究了基于激光圖像識別原理的動態(tài)位移監(jiān)測技術(shù),開展了靜態(tài)、動態(tài)對比試驗,并進(jìn)行了二層框架的動態(tài)位移試驗。試驗結(jié)果證實了使用攝像功能進(jìn)行位移監(jiān)測的可行性,為后續(xù)的研究奠定了基礎(chǔ)。且該方法成本低廉,利于將來的應(yīng)用推廣。
[Abstract]:The disaster caused by natural disasters is shocking, which has caused great threat to the building and bridge structure, caused huge economic losses, and threatened the safety of human life. But natural disasters are unavoidable, so in order to reduce economic losses and protect human life, it is necessary to establish a sound structural health monitoring system to monitor the structure performance and find structural damage in time. Predict possible disasters and evaluate structural safety. At present, the structural health monitoring system has made relatively perfect development, and has been rapidly developed in civil engineering structures, especially in bridge structures, but it is only used in some specific large structures. In order to realize the structural health monitoring more conveniently and quickly, this paper puts forward the concept of cloud monitoring, and carries on a series of exploration and research on this basis. The main tasks are as follows: 1. The concept of cloud monitoring for civil engineering structures is put forward and described in detail. In order to realize the basic function of cloud monitoring, smart phone is selected as the cloud monitoring terminal and control center. Considering the development of smart phone, the parameters of common mobile phone and the sensing performance of its built-in sensor, the feasibility of using smart phone as a cloud monitoring intelligent terminal is demonstrated. 2. A cloud monitoring software system is developed on the IOS platform of iphone4s, including data acquisition program, command control program and network storage program. Achieve the monitoring of GPS information, acceleration, inclination and other monitoring information. 3. The cloud monitoring system has been applied to bridge cable force monitoring, and has been tested in laboratory cable model, Dalian Hualu Bridge and Harbin Sifangtai Bridge. The results of smart phone acceleration acquisition system, piezoelectric acceleration sensor and force balance acceleration sensor are compared and analyzed. The results show that the mobile intelligent terminal developed in this paper can accurately measure the cable force. 4. In order to expand the monitoring parameters of mobile intelligent terminals and the current situation of displacement monitoring difficulties. The dynamic displacement monitoring technology based on the principle of laser image recognition is studied. The static and dynamic contrast tests are carried out, and the dynamic displacement tests of the two-story frame are carried out. The experimental results confirm the feasibility of using the camera function to monitor displacement and lay a foundation for further research. The cost of the method is low, which is beneficial to the future application.
