1、 毕 业 设 计 题 目:基于 ZigBee 及 GPRS 的小 型风电场数据采集系统软件设计 2012 年 6 月 I 基于 Zigbee 及 GPRS 的小型风电场数据采集系统软件设计 摘 要 为实现对风电场现场数据采集的目标而对风电场进行监控,但是传统的 监控系统多采用以太网光纤通讯。对于大型风电场,随着发电机组数量的增 加, 势必增加布线费用, 且当风电场扩充时, 过多的通信线路会造成施工与维 护困难等一系列问题。本课题以 ZigBee 技术和 GPRS 无线分组交换技术为基 础,通过对小型风电场的相关数据的采集,主要包括有风电场的温度、湿度、 风向、风速以及大气压力,来实现对风电场运
2、行状态的实时监控。 本文以小型风电场的数据采集系统为课题背景,论述了 ZigBee 软件平台 的开发过程, 主要完成课题中数据采集系统软件部分设计。 首先介绍了 ZigBee 技术的发展现状和应用前景。其次,介绍了 TI Z-Stack 的软件架构。另外,本 文还介绍了应用层任务处理函数及自定义事件。 关键词关键词:风电场 ZigBee 技术 数据采集 II Software Design of Small Wind Farms Data Collection System Based on Zigbee and GPRS Abstract To achieve the goal of the
3、 wind farm site date acquisition to monitor the winfd farm,but the traditional monitoring system is the use of Ethernet fiber-optic communications. For large wind farms, along with the increase in the number of generating units, certainly will increase wiring fee, and when the wind power expansion,
4、too much communication lines will cause the construction and maintenance difficulties and so on a series of problems. This paper is based on the ZigBee technology and GPRS wireless packet switching technology. By collecting relevant date on small wind farms, including wind farms, temperature, humidi
5、ty, wind direction, wind speed and atmospheric pressure, it finally achieves the purpose of real-time monitoring of the operature status of the wind farm. With the subject background of using the date acquisition system for small-scale wind farm, this paper discusses the development process of the Z
6、igBee software part, mainly to complete the software part design of the data acquisition system in the subject. Firstly it introduces the current situation of the development of ZigBee technology and its development trend. Secondly, it introduces the software architecture of TI Z-Stack. In addition, this paper also describes task handler of the application layer and its custom events. Keywords: wind farm; ZigBee technology; data collector III 目 录 摘 要 . I Abstract .
