【摘要】：随着高校教学水平的提高，实验室在教学和科研中发挥着越来越重要的作用，而实验室的各种设备往往价格昂贵，同时对环境又有某些特殊要求，因此，能否保证实验环境的稳定、实验仪器的正常运转和仪器的财产安全，对高校的科研进步和管理水平具有重要意义。因此，迫切寻求一种合理而有效的技术，使得以较低的成本来保障实验室的安全，是高校实验室环境所亟待解决的问题。在现代短距离无线通信技术发展日新月异的背景下，本课题面向应用为中心，遵循系统稳定性、可靠性、灵活性的原则，以时下最流行的物联网技术——ZigBee无线通信技术为核心，组建成本低、覆盖范围广、组网智能化的无线传感网络。通过终端节点携带多种传感器，，定时进行数据采集发送至协调器节点，同时依靠高校的校园网资源，将无线传感网的采集数据通过基于ARM构架的以太网网关发送至校园网内的服务器主机，安保人员则可以通过客户端上位机实现校园网内任意地点的远程监测，大大提高了实验室远程监测的灵活性和可靠性。本文主要完成了以下工作： (1)分析了系统的整体结构和功能需求，并对ZigBee网络节点和以太网网关的硬件进行了设计。 (2)对ZigBee的三种类型节点的软件协议栈进行了软件设计和功能定制，实现了终端节点定时休眠唤醒并对温湿度、人体红外、烟尘浓度、火焰探测、门磁等信息的采集，并汇总至协调器节点。通过对以太网网关控制器的软件设计，实现了将采集数据发送至以太网服务器的功能。 (3)在VC6.0的中，使用MFC的CSocket类进行网络通信编程，设计了服务端和客户端的上位机软件，实现了服务端的多ZigBee网络数据汇总、多客户端连接和网络通信功能，通过客户端实现校园网内对实验室环境的远程监测。
[Abstract]:With the improvement of teaching level in colleges and universities, laboratories are playing more and more important roles in teaching and scientific research. Whether we can guarantee the stability of the experimental environment, the normal operation of the experimental instruments and the property safety of the instruments is of great significance to the scientific research progress and management level of colleges and universities. Therefore, it is urgent to seek a reasonable and effective technology to ensure the safety of the laboratory at low cost, which is an urgent problem to be solved in the laboratory environment of colleges and universities. Under the background of the rapid development of modern short-range wireless communication technology, the subject is application-oriented and follows the principles of system stability, reliability and flexibility. ZigBee wireless communication technology, which is the most popular technology of the Internet of things nowadays, is the core of the wireless sensor network with low cost, wide coverage and intelligent networking. Through the terminal node carrying a variety of sensors, timing data collection to the coordinator node, while relying on the campus network resources, The data collected from the wireless sensor network is transmitted to the server host in the campus network through the Ethernet gateway based on the ARM architecture, and the security personnel can realize remote monitoring of any location in the campus network through the client PC. The flexibility and reliability of remote monitoring in laboratory are greatly improved. The main work of this paper is as follows: (1) the overall structure and functional requirements of the system are analyzed. The hardware of the ZigBee network node and the Ethernet gateway is designed. (2) the software design and function customization of the software protocol stack of the three types of ZigBee nodes are carried out. Infrared, smoke concentration, flame detection, door magnetism and other information collection, and summarized to the coordinator node. Through the software design of Ethernet gateway controller, the function of transmitting the collected data to Ethernet server is realized. (3) in VC6.0, the CSocket class of MFC is used for network communication programming. The upper computer software of server and client is designed to realize multi-ZigBee network data aggregation, multi-client connection and network communication, and to realize remote monitoring of laboratory environment in campus network through client.
