摘 要
物联网技术正在蓬勃发展，基于具有低成本、低能耗、高安全性等特点的ZigBee技术构建的无线传感网可以实现直线位移的无线监测。本文利用ZigBee模块(CC2530)内嵌高性能和无线收发功能的特点，设计了无线位移监测硬件电路和配套软件，实现了位移的无线监测系统。系统分为两个部分：下位机硬件基于ZigBee无线传感网络的直线位移数据监测和传输部分；上位机软件模块的直线位移数据的存储、管理、动态显示等部分。 在下位机ZigBee直线位移传感网络中，设计了直线位移传感器的终端节点，集成数据传输的协调器节点。在本文的系统中每个节点都使用了完全兼容8051内核和IEEE 802.15.4的CC25 30单片机作为主要芯片，其中无线直线位移传感器节点上面集成了直线位移传感器、LED显示屏、报警电路等模块，其主要功能是采集数据和传输数据。传感器节点在获取到数据后进行AD转换等处理，一方面将监测到的直线位移数据显示在液晶上面，如果检测点的直线位移超过了设置好的阈值，该节点将进行报警提醒；同时另一方面直线位移终端节点将位移数据通过ZigBee网络传送到协调器节点，而协调器节点主要是负责直线位移传感网和上位机软件之间的互联，包括负责系统终端节点的在线情况的控制和实现下位机直线位移传感节点和上位机软件的串口数据通信功能。
在上位机软件开发模块中，使用微软的Visual Studio 2010集成开发环境，利用C#语言开发了windows窗口应用程序。主要是ZigBee协调器和上位机服务器之间的串口通信程序的设计，功能是通过串口通信实现下位机无线传感网数据的传输。其次设计了直线位移数据的存储和动态实时显示的windows窗口。此外，程序还利用数据库表设计了上位机软件的登录窗口和利用开源的ZedGraph控件对串口接收到的直线位移数据实时动态的曲线显示。

things technology is booming, based on low cost, low power, high security features，ZigBee wireless sensor network technology can achieve the wireless monitoring of straight line displacement. this paper ZigBee module High performance and radio functions, the design of a wireless monitoring hardware and supporting software to achieve displacement of wireless displacement monitoring systems.System is divid ed into two parts:lower positi -on machine hardware in linear displacement data monitoring and transmission parts of ZigBee wireless sensor network, cache management, dynamic display portion etc. of linear displacement data of host computer software module.
In lower position machine designed terminal nodes of a linear displacement transducer and a data transfer coordinator node. In the system, each node is fully compatible with the use of 8051-and the CC253 0 single-chip IEEE 802.15.4 as the main chip. which integrate linear displacement sensors, LEDand alarm modules on wireless linear displacement sensor nodes top.室内wifi定位 The ma -in is to collect data and store data.After obtaining the data sensor nodes into the AD conversion process, Then, on the one hand the linear displacement monitored data is displyed on the LCD above, if the linear displac
ement detection point exceeds the maximum of set a good, the node corresponding remind超导无轴陀螺空天载具s, to make preventive measures; and on the other hand the linear displacement terminal nodes transverse displacement data to the coordinator node by ZigBee network, a频率元件nd the coordinator node is mainly responsible for the linear displacem ent sensor network interconnection and PC software. that is responsible for the system nod -e control line situation and achieve serial data communication lower position machine linear displacement sensor nodes and PC software.
In the host computer software development module, using Visual Studio and using C # language to develop Windows server window applications. Mainly includes design ZigBee coordinator between the server and PC serial communication program, function is to achieve lower position machine to transfer data wireless sensor network through the serial communication. Secondly, the design of the linear displacement data caching and dynamic real-time display of windows window the program also use the database table designed PC software login window and using open source Zed Graph control to the serial data received in real-time dynamic linear displacement by curves displayed.
