【摘要】 人们对道路交通气象信息的需求日益增长,而道路结冰是道路交通气象要素中最为重要的要素之一,与人们的日常生活、生产密不可分。因此,道路结冰的测量有着重要的意义。本文在大量查阅了国内外结冰探测方法的基础上,设计了基于ZigBee协议的高速公路路面结冰检测系统。该系统利用温度、路面阻值、振动信息三个参数来综合判断路面结冰状况。针对高速公路中采集的终端节点数目多,分布范围广等特点,利用ZigBee无线传感器网络技术来进行数据的传输。本文首先阐述了论文研究背景、意义和价值,接着对ZigBee协议进行了研究并详细介绍了检测系统的总体设计方案,然后对系统的终端节点与协调器节点部分进行了详细的理论分析和设计。同时,本文根据高速公路的特点设计了符合实际情况的无线传感器网络,实现了数据的收发与系统的监测。并在最后给出了数据采集的方案、数据处理的方法与实验结果。本文利用CC2530无线单片机作为现场智能检测仪表的终端节点、路由器节点、协调器节点(用于现场监控以及远程通信)。在基于CC2530无线芯片的基础上,根据实际道路路面状况的区别,利用ZigBee协议组成了多种网络,实现了对温度、路面阻值等常规参数的检测。经过测试,本系统工作稳定可靠,具有一定的市场价值和良好的发展前景。更多还原

【Abstract】 With the problems of population, resources, environment and disaster in modern society are becoming increasingly prominent, people have growing demand on road traffic weather information and meteorological service. Ice road is one of the most important road meteorological elements inseparable with people’s daily life. Therefore, the measurement of icy roads has important significance,In this paper, an icy detection system on highway road based on ZigBee protocol is designed after a lot of access to domestic and foreign ice detection methods. Three parameters, temperature, pavement resistance and vibration information are taken into account to judgment pavement icy condition. Aiming at the features of big number of terminal nodes, widely distributing range, etc, the technology of ZigBee wireless sensor network is used for data transmission. First, this paper states the research background, importance and value, and introduces the overall system design in detail. Then, depth study and research of ZigBee protocol is conducted and detailed theoretical analysis and hardware design about terminal nodes and coordinator nodes are given. Meanwhile, according to the characteristic of highway, this paper designs wireless sensor network suitable for realistic situation, to achieve data transceiver and system monitoring. And finally solution of data collection, method of data processing and experiment results are given. CC2530 wireless microcontrollers are smart field instrumentation of terminal nodes, router nodes and coordinator nodes (for on-site monitoring and remote communication). According to the actual road surface conditions, based on CC2530 wireless chip, various of networks are made up with ZigBee protocol, to realize detection of temperature, road surface resistance and other conventional parameters. After cyclic test, the designed system works stable and reliable so that it has market value and good prospects for development.更多还原
