ZigBee无线传感器网络温度采集系统的设计(任务书,开题报告,论文12000字)
摘 要
科技发展蒸蒸日上，网络的传统布线方式显现出局限性，因此，无线传感器网络受到关注，其中，ZigBee技术因其低功耗、低成本、自组织等优点，广泛应用于国防、工业、农业等领域。ZigBee技术在监控方面，已成为首屈一指的技术，而对温度数据的采集，是一个非常基础且重要的要求，本文以此为出发点，设计一个基于ZigBee无线传感网络的温度采集系统。
本文首先对温度采集系统进行了整体的规划设计，然后再对协调器、终端进行软硬件设计。硬件部分，协调器节点和终端节点均选用CC2530作为主要芯片，终端节点通过传感器设备采集到温度数据无线传输给协调器节点，协调器节点处理后通过串口发送给电脑。软件部分，本文成功配置了Z-stack协议栈、编写了温度数据采集程序，最终实现了温度数据的采集和传输。
本文设计的温度采集系统，不仅搭建简单、部署容易，而且数据传输实时、有效、安全，为ZigBee技术在监测方面的实际应用打下了坚实的基础，为以后的扩展提供了一定的思路与参考价值。

Design of Temperature Acquisition System Based on ZigBee Wireless Sensor Networks
Abstract
As technology advances, the traditional wiring of networks increasingly showing its limitations. So, people pay more and more attention to the wireless sensor networks. Among them, ZigBee technology is widely used in national defense, industry, agriculture areas because of the advantages of low power, low cost and self-organization. ZigBee technology has become a leading technology in monitoring, and temperature data collection is a very basic and important requirement. take it as a starting point to design a temperature acquisition system based on ZigBee wireless sensor networks.
Firstly, this article plan and design temperature acquisition system for the overall. It is mainly based on the principle of ZigBee wireless communication protocol, ZigBee network coordinator nodes and ZigBee end nodes to construct a simple star network topology, and then designs the coordinator nodes and the terminal nodes hardware and software. Hardware part, chip CC2530are selected as the main chip of the coordinator nodes and the end nodes. The end node collects temperature data by sensor device and transmits them to the coordinator node wirelessly. Then the coordinator node processes them and sends them to the computer. Software part, this article successfully configured the Z-stack and prepared temperature data acquisition program. The collection and transmission of temperature data was finished ultimately.
The design of temperature acquisition system is not only simple and easy, but also transmits in timely, effectively and safely. It builds a solid foundation on practical application in the monitoring laid of ZigBee technology. It also provides some ideas and reference for future extensions.
