【摘要】：未来的世界无疑将是一个伴随着泛在计算和网络的智能化世界，而物联网（the Internet ofThings，IoT）会是实现这一目标的重要途径。实验室作为高校用于教学和科研的重要场所，其管理水平在一定程度上对高校的发展起到了影响作用。因此，针对当前实验室管理效率低、信息化程度低的问题，以及为了探索智能实验室的应用需求和特点，本文基于物联网技术对智能实验室系统进行了研究，给出了完整的解决方案，在此基础上搭建了一个智能化实验室系统的模型。论文首先以实验室管理和物联网的发展应用为背景，分析了国内外的相关研究情况，论述了研究智能实验室系统的必要性与现实意义，并对课题的研究内容、技术难点、创新点和内容安排做了说明。其次，从全局的角度出发综合阐述了系统的整体框架和设计方案，详细介绍了系统涉及到的关键技术的背景和内容。系统的整体框架结构来自于物联网体系的分层架构，最上层是以Web服务器、PHP和MySQL等技术搭建的服务器层，对应于物联网中的应用层；中间层是以嵌入式技术为主的网关，对应于物联网中的网络层；最底层是以ZigBee、传感器、微控制器和RFID等技术组织而成的无线传感网络，对应于物联网中的感知层。出于设计、安装和维护的便利性，对无线传感网络采用了分离结构，将其中的节点拆分为ZigBee节点和终端控制器两个部分，前者负责无线网络的组网和信息的传递，后者负责底层具体硬件的数据读取和控制。然后，全面深入讲述了系统各层和各个模块的软硬件设计。系统的网关以ARM处理器为核心，，主要负责服务器层和无线传感网络之间的信息转换，并且结合Qt和触摸屏技术对部分信息进行了显示，是整个系统的中间层。无线传感网络建立在ZigBee网络的基础之上，综合运用多种传感器和微控制器、RFID、继电器、电子锁等，实现了环境信息的采集、实验设备的电源控制和门禁等功能。服务器层通过Web服务器和数据库的搭建，方便了管理人员和老师通过远程登录进行相关的监控。最后对根据上述方案设计的智能实验室系统进行了分块和整体的测试。测试结果表明，所设计的智能实验室系统实现了设计前的功能需求，达到了方案设计时设定的各项指标。系统整体层次分明，结构严谨，远程监控稳定可靠，为智能实验室的研究提供了模型。
[Abstract]:There is no doubt that the future world will be an intelligent world with ubiquitous computing and network, and the Internet of things will be an important way to achieve this goal. As an important place for teaching and scientific research in colleges and universities, the management level of laboratories has played an important role in the development of colleges and universities to some extent. Therefore, aiming at the problems of low efficiency of laboratory management and low degree of information, and in order to explore the application requirements and characteristics of intelligent laboratory, this paper studies the intelligent laboratory system based on the technology of Internet of things. A complete solution is given, and a model of intelligent laboratory system is built. Firstly, based on the development and application of laboratory management and Internet of things, this paper analyzes the relevant research situation at home and abroad, discusses the necessity and practical significance of the research on intelligent laboratory system, and discusses the research contents and technical difficulties of the subject. Innovation points and content arrangements are explained. Secondly, the overall framework and design scheme of the system are expounded from the overall perspective, and the background and content of the key technologies involved in the system are introduced in detail. The whole frame structure of the system comes from the hierarchical architecture of the Internet of things system. The top layer is the server layer based on Web server and MySQL, which corresponds to the application layer in the Internet of things, and the middle layer is the gateway based on embedded technology. It corresponds to the network layer in the Internet of things, and the lowest layer is the wireless sensor network organized by ZigBee, sensor, microcontroller and RFID, which corresponds to the sensing layer in the Internet of things. For the convenience of design, installation and maintenance, the wireless sensor network is divided into two parts: the ZigBee node and the terminal controller. The former is responsible for the networking and information transmission of the wireless network. The latter is responsible for the data reading and control of the underlying hardware. Then, the software and hardware design of each layer and module of the system is described in detail. The gateway of the system takes the ARM processor as the core, mainly responsible for the information conversion between the server layer and the wireless sensor network, and displays part of the information with the combination of QT and touch screen technology, which is the middle layer of the whole system. Wireless sensor network is built on the basis of ZigBee network. The functions of environment information collection, power supply control and access control of experimental equipment are realized by synthetically using various sensors and microcontrollers such as RFID, relay, electronic lock and so on. The server layer is built by Web server and database, which makes it convenient for managers and teachers to monitor by remote login. Finally, the intelligent laboratory system designed according to the above scheme has been divided into blocks and tested as a whole. The test results show that the designed intelligent laboratory system meets the functional requirements before design and meets the requirements set in the scheme design. The system is well-structured, stable and reliable, and provides a model for the research of intelligent laboratory.
