【摘要】：近年來,隨著計算機技術(shù)與網(wǎng)絡技術(shù)的快速發(fā)展,人們對先進的自動化監(jiān)控技術(shù)在建筑領(lǐng)域中的應用投入了愈來愈多的關(guān)注。我國建筑業(yè)屬于勞動密集型產(chǎn)業(yè),傳統(tǒng)的施工管理方法多采用人工方式進行現(xiàn)場數(shù)據(jù)的收集、分析與處理。這種人工方式不僅耗時長、占用資源多,而且數(shù)據(jù)準確性低、信息傳遞滯后,不能為管理者的決策提供實時支持。因此,研究基于實時信息的施工現(xiàn)場自動化監(jiān)控管理,輔助管理者實時做出正確的決策,具有重要的現(xiàn)實意義。 本文將計算機技術(shù)、無線通信技術(shù)、網(wǎng)絡技術(shù)、測控技術(shù)與施工管理相結(jié)合,以施工現(xiàn)場溫度因素為監(jiān)控指標,對基于ZigBee無線傳感器網(wǎng)絡的施工現(xiàn)場環(huán)境溫度自動監(jiān)控系統(tǒng)進行研究。 首先,在參閱大量文獻的基礎(chǔ)上,分析了各種自動化監(jiān)控技術(shù)在建設施工領(lǐng)域中的研究與應用,總結(jié)了現(xiàn)有研究的主要方向,并提出現(xiàn)有研究的不足,將自動化監(jiān)控技術(shù)引入到施工管理領(lǐng)域,為后續(xù)研究奠定基礎(chǔ)。 其次,對ZigBee、超寬帶、Wi-Fi、藍牙及RFID幾種無線通信技術(shù)進行闡述,詳細分析了這些技術(shù)的工作原理、技術(shù)特點及適用的應用環(huán)境。并對無線傳感器網(wǎng)絡進行概述,提出了其在建筑領(lǐng)域中的潛在應用情境。 而后,基于ZigBee無線傳感器網(wǎng)絡架構(gòu),提出了施工現(xiàn)場環(huán)境溫度自動監(jiān)控系統(tǒng)感知層、網(wǎng)絡層、應用層的三層系統(tǒng)結(jié)構(gòu)。通過對系統(tǒng)各硬件的工作原理和性能進行分析,詳細闡述了溫度傳感器、無線傳感器節(jié)點、網(wǎng)關(guān)、主控制器之間的連接,設計了系統(tǒng)的硬件平臺。 再次,設計了系統(tǒng)的總體功能結(jié)構(gòu),提出了系統(tǒng)的參數(shù)設置模塊、采集控制模塊、數(shù)據(jù)顯示模塊、實時監(jiān)測模塊、限值警報模塊、數(shù)據(jù)分析模塊及數(shù)據(jù)存儲模塊。并基于虛擬儀器技術(shù),以模塊化設計為程序設計思想,采用LabVIEW圖形化編程語言對這些模塊進行功能設計 最后,進行了室內(nèi)外環(huán)境溫度監(jiān)控實驗,對系統(tǒng)硬件的連接、組網(wǎng)的實現(xiàn)、硬件與軟件的集成和實時溫度監(jiān)控的效果進行測試,驗證了系統(tǒng)的可行性。并對系統(tǒng)溫度監(jiān)控的影響因素進行分析,提出相應的解決對策。
[Abstract]:In recent years, with the rapid development of computer technology and network technology, people pay more and more attention to the application of advanced automatic monitoring technology in the field of architecture. Construction industry in China belongs to labor-intensive industry. The traditional construction management methods adopt manual method to collect, analyze and deal with the field data. This manual method not only takes up time, takes up more resources, but also has low data accuracy and information transmission lag, which can not provide real-time support for managers' decision-making. Therefore, it is of great practical significance to study the automatic monitoring and management of construction site based on real-time information to assist managers to make correct decisions in real time. In this paper, computer technology, wireless communication technology, network technology, measurement and control technology and construction management are combined, and the temperature factor of construction site is taken as the monitoring index. Based on ZigBee wireless sensor network, the environment temperature automatic monitoring system of construction site is studied. First of all, on the basis of consulting a large number of literatures, this paper analyzes the research and application of various automatic monitoring technologies in the construction field, summarizes the main directions of the existing research, and puts forward the shortcomings of the existing research. The automatic monitoring technology is introduced into the construction management field to lay the foundation for the follow-up research. Secondly, several wireless communication technologies such as ZigBee, UWB Wi-Fi, Bluetooth and RFID are described. The working principle, technical characteristics and applicable application environment of these technologies are analyzed in detail. The potential applications of wireless sensor networks in the field of architecture are presented. Then, based on the ZigBee wireless sensor network architecture, a three-layer system structure is proposed, which is the perceptual layer, the network layer and the application layer of the environment temperature automatic monitoring system in the construction site. By analyzing the working principle and performance of the hardware of the system, the connection between temperature sensor, wireless sensor node, gateway and main controller is described in detail. The hardware platform of the system is designed. Thirdly, the overall functional structure of the system is designed, and the parameter setting module, the collection and control module, the data display module, the real-time monitoring module, the limit alarm module, the data analysis module and the data storage module are put forward. Based on the virtual instrument technology, the modular design is taken as the programming idea, and the LabVIEW graphical programming language is used to design the function of these modules. Finally, the indoor and outdoor environment temperature monitoring experiments are carried out, and the hardware of the system is connected. The realization of network, the integration of hardware and software and the effect of real time temperature monitoring are tested, and the feasibility of the system is verified. The influencing factors of system temperature monitoring are analyzed, and the corresponding countermeasures are put forward.
