【摘要】：高校中的开放实验室能够为学生提供自主学习和工程实践的平台,有助于学生实践能力和创新能力的培养,同时可以提高实验室设备的使用效率。然而,开放实验室的管理工作却变得更加繁杂,加重了实验室管理人员的工作负担,增加了管理成本,于是,针对开放实验室的信息管理系统不断出现,很大程度上解决了这一问题。但是,除了计算机房以外,对于其它开放实验室,由于没有计算机及网络设备,现有针对开放实验室的信息管理系统大多存在自动化管理程度不高的问题。物联网技术的发展,为高校开放实验室建设和智能化管理提供了技术支撑。基于物联网的开放实验室信息管理系统涉及传感器技术、射频识别技术、无线通信技术、计算机技术等物联网紧密相关技术,智能感知系统和嵌入式网关是其最核心的组成部分。本文以无线射频模块CC2530为核心器件,设计实验室环境参数感知节点、无线门禁终端节点、智能电源插座终端节点和协调器节点,基于ZigBee协议自组织形成无线传感器网络,以此构成开放实验室智能感知系统,从而实现环境参数的智能感知、无线门禁和电源的自动控制功能。为了实现智能感知系统将感知信息接入Internet,实现与服务器之间的信息交互,方便用户通过Web浏览器访问实验室内部资源,对智能感知系统进行控制,本文设计了Web嵌入式网关。本文详细阐述了智能感知系统中环境参数感知节点、无线门禁终端节点、智能电源插座终端节点和协调器节点,以及嵌入式网关的软硬件设计方法,完成了系统调试。所设计系统可以满足开放实验室智能化管理的基本硬件系统要求,有效解决了传统开放实验室自动化管理程度不高、实验室改造过程中布线困难、缺乏环境状态感知与监控等问题,可以实现开放实验室无人化(或少人化)的智能化管理,从而节约管理成本,提高管理效率,提升管理水平。
[Abstract]:The open laboratory in colleges and universities can provide students with a platform for independent learning and engineering practice, which is helpful to the cultivation of students' practical and innovative abilities, and can also improve the efficiency of the use of laboratory equipment. However, the management of open laboratories has become more complicated, increasing the workload of laboratory managers and increasing management costs. Therefore, information management systems for open laboratories continue to appear. To a large extent, this problem has been solved. However, except for the computer room, for other open laboratories, because of the lack of computer and network equipment, most of the existing information management systems for open laboratories have the problem of low degree of automation management. The development of Internet of things technology provides technical support for the construction of open laboratory and intelligent management in colleges and universities. The open laboratory information management system based on the Internet of things involves sensor technology, radio frequency identification technology, wireless communication technology, computer technology and other closely related technologies of the Internet of things. Intelligent sensing systems and embedded gateways are the core components. In this paper, the wireless RF module CC2530 is used as the core device to design the laboratory environment parameter sensing node, wireless access terminal node, intelligent power outlet terminal node and coordinator node. Based on ZigBee protocol, the wireless sensor network is self-organized. An open laboratory intelligent sensing system is constructed to realize the intelligent sensing of environmental parameters, wireless access control and automatic control of power supply. In order to realize the intelligent perception system to connect the perceptual information into Internet, to realize the information interaction with the server, to facilitate the users to access the laboratory internal resources through the Web browser, and to control the intelligent perception system, the Web embedded gateway is designed in this paper. In this paper, the software and hardware design methods of environment parameter sensing node, wireless access terminal node, intelligent power outlet terminal node and coordinator node, as well as embedded gateway are described in detail, and the system debugging is completed. The designed system can meet the basic hardware system requirements of intelligent management of open laboratory, and effectively solves the difficulty of wiring in the process of laboratory transformation, because the degree of automation management in traditional open laboratory is not high. The lack of environmental state perception and monitoring can realize the intelligent management of open laboratory, which can save the management cost, improve the management efficiency and improve the management level.
