【摘要】：近年来,随着计算机技术与网络技术的快速发展,人们对先进的自动化监控技术在建筑领域中的应用投入了愈来愈多的关注。我国建筑业属于劳动密集型产业,传统的施工管理方法多采用人工方式进行现场数据的收集、分析与处理。这种人工方式不仅耗时长、占用资源多,而且数据准确性低、信息传递滞后,不能为管理者的决策提供实时支持。因此,研究基于实时信息的施工现场自动化监控管理,辅助管理者实时做出正确的决策,具有重要的现实意义。本文将计算机技术、无线通信技术、网络技术、测控技术与施工管理相结合,以施工现场温度因素为监控指标,对基于ZigBee无线传感器网络的施工现场环境温度自动监控系统进行研究。首先,在参阅大量文献的基础上,分析了各种自动化监控技术在建设施工领域中的研究与应用,总结了现有研究的主要方向,并提出现有研究的不足,将自动化监控技术引入到施工管理领域,为后续研究奠定基础。其次,对ZigBee、超宽带、Wi-Fi、蓝牙及RFID几种无线通信技术进行阐述,详细分析了这些技术的工作原理、技术特点及适用的应用环境。并对无线传感器网络进行概述,提出了其在建筑领域中的潜在应用情境。而后,基于ZigBee无线传感器网络架构,提出了施工现场环境温度自动监控系统感知层、网络层、应用层的三层系统结构。通过对系统各硬件的工作原理和性能进行分析,详细阐述了温度传感器、无线传感器节点、网关、主控制器之间的连接,设计了系统的硬件平台。再次,设计了系统的总体功能结构,提出了系统的参数设置模块、采集控制模块、数据显示模块、实时监测模块、限值警报模块、数据分析模块及数据存储模块。并基于虚拟仪器技术,以模块化设计为程序设计思想,采用LabVIEW图形化编程语言对这些模块进行功能设计最后,进行了室内外环境温度监控实验,对系统硬件的连接、组网的实现、硬件与软件的集成和实时温度监控的效果进行测试,验证了系统的可行性。并对系统温度监控的影响因素进行分析,提出相应的解决对策。
[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.
