基于ZigBee技术的自习室人数监测系统设计(论文14000字)
摘要ZigBee 是无线传感器网络的部署和应用的一项新技术。ZigBee网络协议和 IEEE802.15.4 技术标准为ZigBee的开发提供了基础。射频信号作为无线数据传输的手段，这一波段下的信号传输功耗很低，相对来说，开发成本也不高。每一个端节点需要的电能很少,在只有电池供电的情况下,也能够持续供电很长时间。本文利用ZigBee 技术和红外关电传感器的结合,用来完成 ZigBee 无线传感器网络的建立,实现一个协调器点对应多个终端节点之间的通信。ZigBee技术的在生活着还有很多的应用，例如：智能家居、楼宇自动化、现代化农业的控制、现代化交通的监测等多个领域[1]。
本文是把ZigBee技术应用到人数监测系统中，实现对自习室中学生人数的监测与显示，以便于学生查询并找到合适的自习教室。同时也完成了每个节点的硬件设计及焊接和软件的编写工作。节点可划分为电源模块、教室计数模块、LCD显示等模块。考虑到成本、通信数据量以及功耗和安全问题，本文将以CC2530作为本次设计的主控芯片。人数采集模块才采用的是红外光电传感器，该传感器开发成本低，测量精度在可接受范围之内。软件程序的是在TI公司开发的ZigBee协议栈--Z-Stack的基础上进行修改，包括串口的通信、数据的采集、网络组建、无线通信等程序的编写。经过不断的硬件的修改和软件的调试，系统的网络组建和数据传输功能得到了充分的证明。 [来源：http://Doc163.com]

The Monitoring System of Self - study Room Based on ZigBee Technology
Abstract：ZigBee is a new technology for the deployment and application of wireless sensor networks.ZigBee network protocol and IEEE802.15.4 technical standards for the development of ZigBee provides the basis.RF signal as a means of wireless data transmission,The signal transmission power in this band is very low.Relatively speaking, the development costs are not high.Each end node needs little power.In the case of battery-powered, but also can continue to power for a long time.In this paper, the combination of ZigBee technology and infrared power sensor is used to complete the establishment of ZigBee wireless sensor network, and realize that a coordinator point corresponds to the communication between multiple terminal nodes.ZigBee technology in the life there are many applications, such as: smart home, building automation, modern agricultural control, modern traffic monitoring and other fields.
