基于ZigBee的室内环境检测系统的设计(论文15000字)
摘要:随着人们生活水平的不断提高,人们对室内环境质量的需求也变得越来越高。本文主要是根据国内目前的家居环境监测的发展现况,设计了一个基于CC2530的室内环境检测系统。该系统利用以CC2530为核心的无线传感模块实现点对点通信,通过协调器进行环境参数数据的接受和转发,而传感器节点进行环境参数的测量和转发,上位机软件进行环境参数的显示和检测。本论文主要是讨论了以CC2530芯片为核心的相关ZigBee无线传感网络模块的技术背景、其基于的IEEE802.15.4标准、其协议体系结构、技术特点和实现的基本方式[1],分析了硬件设计实现的可行性。并对本设计采用的温湿度传感模块、烟雾传感模块、人体感应传感模块以及OLED显示模块进行的简要的说明与分析。本文还简单地阐述了有关上位机软件的设计。最后对温湿度、烟雾和人体感应的功能效果进行测试和简单的认证,并总结分析验证结果。实验证明,这种设计结构非常简单,使用与操作相当方便,功能较为齐全,在现实中具有一定的实用价值。

Indoor Environment Detection System Based on ZigBee
Abstract:With the continuous improvement of people's living standards, people's demand for indoor environmental quality has become increasingly high. This paper is based on the current domestic home environment monitoring the development of the status of the design of a CC2530 based on the indoor environment testing system. The system uses the wireless sensor module with CC2530 as the core to realize point-to-point communication. The parameters and data of the environmental parameters are accepted and forwarded by the coordinator. The sensor nodes carry out the measurement and forwarding of the environmental parameters. The host computer software displays and detects the environmental parameters. This paper mainly discusses the technical background of the related ZigBee wireless sensor network module with CC2530 chip as its core, which is based on the IEEE802.15.4 standard, its protocol architecture, technical characteristics and the basic way of realization [1]. The hardware The feasibility of the design realization. And the design and use of the temperature and humidity sensor module, smoke sensor module, the human body sensor module and OLED display module for a brief description and analysis. This article also briefly describes the design of the host computer software. Finally, the functional effects of temperature and humidity, smoke and human induction are tested and simply authenticated, and the results are analyzed and summarized. Experiments show that this design structure is very simple, easy to use and operation, the function is more complete, in reality has a certain practical value.
