基于ZigBee的WSN室内有毒气体检测系统5-27.docVIP

摘要 改革开放以来，随着社会经济的飞速发展，人们的生活水平越来越高。 随着人们整体环保意识的增强，人们对室内的空气质量也越来越重视。 本设计根据应用实际，设计了一种基于ZigBee的WSN室内有毒气体检测系统。结合物联网技术、传感与监测技术、计算机控制技术，互联网通信技术等，基于ZigBee所组建的无线传感通信网络（WSN），配合各种气体传感器，通过控制端（上位机）、协调器、终端节点（下位机）三层机构，对室内控制质量参数进行采集，并且可以在任何一台安装有上位机软件的PC机上显示、查看室内空气参数信息。 设计工作以关系生活实际为出发点，在本科所学专业为基础，前期调研了大量的学术论文，总结前人研究方式，结合自己的研究实际，完成本次论文。在硬件方面主要先采取protel画图软件，设计出系统各部分的电路图，完成器件选型，并依据电路图焊接器件。根据各部分电路所要实现的功能，在已有程序的基础上进行修改，烧录程序，在Protues上进行仿真运行，根据运行情况进行硬件和软件的调试工作。 本次设计的基于ZigBee的WSN室内有毒气体检测系统与国外相应产品相比较，实现了远程控制功能，成本较低、性能稳定、能耗较低、组网简单、扩展方便，完全适合用于家庭室内空气环境的监测。 关键词：有毒气体；物联网；ZigBee；WSN；传感器 Abstract Since Chinas reform and opening up, with the rapid development of social economy, peoples standard of living is higher and higher. As people overall environmental protection consciousness enhancement, people on indoor air quality is becoming more and more attention. The design according to the actual application, designed WSN indoor toxic gas detection system for ZigBee-based. Combination of networking technology, sensing and monitoring technology, computer control technology, the Internet and other communication technologies, ZigBee wireless sensor by the formation of a communications network (WSN) based, with a variety of gas sensors, the control terminal (PC), the coordinator the terminal node (the crew) three-tier mechanism, indoor quality control parameters for the collection, and can be displayed on any computer equipped with a PC software PC, view the indoor air parameters. Design work in relation to real life as the starting point, in undergraduate science professional basis, a lot of preliminary research papers, previous research mode, combined with their actual study, the completion of this thesis. In terms of hardware taken protel first major drawing software to design a circuit diagram of the various parts of the system, complete device selection, and based on a circuit diagram of the welding device. Each part of the circuit according to the functions to be achieved, on the basis of the exist
