摘要 无线传感器网络的诞生解决了对布线困难的区域、人员不能到达的区域进行数据采集的问题，同时也简化了有线网络所带来的规划布线、预设接口、线路检测、线路扩容等一系列和传输途径有关的繁琐工作。目前无线传感器网络市场几乎被国外厂商占领，这严重阻碍了我国无线数据采集系统的发展。 课题的目的是设计出一套能够实现基本应用的无线实时数据采集系统，以检验本科学习成果。该系统的特点是设计简单、实时性强、系统稳定。其功能包括数据采集节点对模拟信号的采集、ZigBee无线网络对数据的无线传输、实时数据显示、数据报警等。监控人员可以根据上位机上监控系统所显示的数据报表、报警状态对被测对象进行相应的、及时有效的处理。课题以ZigBee芯片CC2430作为无线网络的核心，调整整个无线网络的的正常运行；上位机和无线网络的数据交互:通过组态软件实现无线传感器网络与实时数据库的连接并产生友好的人机界面，方便管理人员管理数据、及时了解数据采集现场的情况。 本文所做的主要工作: l、在研究 IEEE802.15.4/ZigBee协议的基础上，构建了ZigBee无线星型通信网络，实现了ZigBee星型网的基本应用。 2、完成了ZigBee网络节点的硬件设计，包括节点硬件原理图设计、节点硬件电路制作以及硬件电路的调试。 3、完成了各节点通信的软件设计，主要包括终端节点数据采集程序的编写和各节点相互通信的软件设计，实现了终端节点对环境温度的采集以及点到点之间的通信。 关键词: 无线数据采集系统， ZigBee， CC2430， LCD1602 ABSTRACT Wireless sensor network is born to address the difficult wiring area, staff can not reach the regional data collection issues, but also simplifies the wiring cable network planning, design interface, line detection, line expansion and a series of and transmission pathways related to the tedious work. The wireless sensor network market was almost foreign manufacturers are occupied, which seriously hampered Chinas wireless data acquisition system development. The purpose of this study is to design a set to achieve the basic application of the wireless data acquisition system, in order to test the undergraduate learning outcomes. The system is characterized by simple design, strong real-time, system stability. Its functions include data acquisition node to the analog signal acquisition, ZigBee wireless network for the wireless transmission of data, real-time data display, alarm and other data. Monitoring based on computer monitoring system of the displayed data statements, alarm state of the tested object was appropriate, timely and effective treatment. Topic in ZigBee CC2430 chip as the core of wireless network, adjust the entire wireless network normal operation; PC and wireless network data interaction: through the configuration software to realize the wireless sensor network and real time database conn
