【摘要】：为了解决“十二五”期间农网改造依旧留存的问题,进一步扫清农网自动化方向上的阻碍,“十三五”新一轮农网改造升级工程将围绕“升级”开展重点工作——机井通电。目前,该项目尚处于发展期,各项技术还不成熟,并且由于管理、设备基础等原因,排灌配电设施存在缺陷,存在私自拉线转供电的现象,用电管理混乱,机井电能计量终端的安全无保障,存在不容忽视的安全隐患。为了时刻采集机井电能计量终端的数据,监控其运行情况,本文将利用无线通信技术设计一种采集抄表系统,将机井计量终端装置的数据及运行状态通过短距离无线通信技术传送到该区域的变电室的网络协调器中。网络协调器通过远程无线通信技术将数据远程传送到电力管理后台系统中以及抄表员的手持终端上,实现远程数据抄读和对计量终端安全的监控功能。系统主要涉及数据终端采集系统和网络协调器两个部分。短程无线传输以ZigBee技术为基础组建了采集抄表网络,在此基础上增加了功放模块扩大传输距离,远程无线传输以GPRS技术为基础完成与电力管理中心的网络连接。本文在分析ZigBee和GPRS无线通信技术特点的基础上,实现了数据采集终端和网络协调器的硬件电路设计焊接和软件代码编写。通过大量实验对系统进行测试,结果表明:系统可以准确完成计量终端的电能数据采集传输工作,实现对机井电能计量终端安全的监控功能。
[Abstract]:In order to solve the problem that the transformation of rural power network remains during the 12th Five-Year Plan period, and to further clear the obstacles in the direction of agricultural network automation, a new round of the "13th Five-Year Plan" rural network renovation and upgrading project will focus on the "upgrade" and focus on "upgrading". The project is still in the developing stage, the technology is not mature, and because of the management, equipment foundation and other reasons, the drainage and irrigation distribution facilities have defects, there is the phenomenon of private pulling lines to power supply, and the power management is chaotic. In order to collect the data of the electric energy metering terminal and monitor the operation of the terminal, this paper will design a meter reading system using wireless communication technology. The data and operating state of the terminal unit are transmitted to the network coordinator of the substation room in the area via short-distance wireless communication technology. The network coordinator transmits data remotely to the electricity through remote wireless communication technology. In the power management backstage system and the handheld terminal of the meter reader, The system mainly involves two parts: data terminal acquisition system and network coordinator. Short-range wireless transmission is based on ZigBee technology. On this basis, the power amplifier module is added to expand the transmission distance, and the remote wireless transmission is based on GPRS technology to complete the network connection with the power management center. This paper analyzes the characteristics of ZigBee and GPRS wireless communication technology. The hardware circuit design and software code of data acquisition terminal and network coordinator are designed and welded. The system is tested by a large number of experiments. The results show that the system can accurately complete the power data acquisition and transmission work of the measurement terminal. Realize the monitoring function of electric energy measurement terminal safety.
