【摘要】：目前,室内空气质量问题通常由多方面因素引起,其中一方面因素便是人们日常生活中由于粗心或者设备故障引起的诸如水煤气、天然气、液化石油气之类的有害气体泄漏,给人体带来危害。本课题根据实际需求,研究并设计一种面向室内空气质量监测的无线传感器网络,其主要针对室内空气中温度、湿度以及可燃气体进行检测并进行自动调控,其不仅能够能够有效的保护人们的身体健康,同时使得许多家庭的灾难得以避免。本文以室内空气质量监测系统为研究对象,首先对无线传感器网络以及家庭燃气泄漏的重大危害进行分析;结合系统功能及需求,对系统总体设计方案进行设计,并对Zigbee无线网络以及Z-Stack协议栈的关键技术进行研究;设计了室内空气质量检测终端、Zigbee路由器、Zigbee协调器以及上位机实时监测软件,并应用相关理论技术对具体实现过程进行了分析和研究;通过对系统功能的测试,验证了系统能够正常稳定的工作,且具有较高的检测精度。在室内空气质量监测系统中,选用TI公司的CC2530微处理器芯片作为本系统的主控芯片,用于构建Zigbee无线网络中的三种设备对象,并配合智能传感器以及上位机实时监测软件,实现对室内空气中温度、湿度、可燃气体浓度的实时监测、显示以及超限自动调控的功能。同时,能将一段时间内温湿趋势以曲线的方式表示,使监测结果一目了然。Z-Stack协议栈的使用,大大缩短了系统开发的周期,提高了系统的稳定性、可靠性以及可维护性。
[Abstract]:At present, indoor air quality problems are usually caused by various factors, one of which is the leakage of harmful gases such as water gas, natural gas, liquefied petroleum gas, etc., caused by carelessness or equipment failure in people's daily life.Bring harm to human body.According to the actual demand, this paper studies and designs a wireless sensor network for indoor air quality monitoring, which mainly detects and automatically controls indoor air temperature, humidity and combustible gas.It not only can effectively protect people's health, but also make many families to avoid disasters.In this paper, the indoor air quality monitoring system is taken as the research object. Firstly, the major harm of wireless sensor network and gas leakage is analyzed, and the overall design scheme of the system is designed according to the functions and requirements of the system.The key technologies of Zigbee wireless network and Z-Stack protocol stack are studied, and the indoor air quality detection terminal, Zigbee router, Zigbee coordinator and host computer real-time monitoring software are designed.Through testing the function of the system, it is verified that the system can work normally and stably, and has high detection precision.In the indoor air quality monitoring system, the CC2530 microprocessor chip of TI company is chosen as the main control chip of the system, which is used to construct three kinds of equipment objects in the Zigbee wireless network, and cooperate with the intelligent sensor and the real-time monitoring software of the host computer.The functions of real-time monitoring, display and automatic control of indoor air temperature, humidity and flammable gas concentration are realized.At the same time, the trend of temperature and humidity over a period of time can be expressed as a curve, so that the monitoring results can be clearly used in the .Z-Stack protocol stack, which greatly shortens the period of system development and improves the stability, reliability and maintainability of the system.
