基于GPRS的配电变压器在线监控系统研究

Research on On-line GPRS-based Monitoring System of TTU

针对TTU的国内外发展现状,在广泛的市场调查的基础上,提出了一种基于UPSD3334单片机和GPRS通信技术的配电变压器在线监控系统整体设计方案。并根据配电数据的采集原理和电参量的计算方法,实现了硬件系统设计及配电变压器检测终端与主站监控中心管理系统软件的开发。同时进行了软、硬件的抗干扰设计。实验结果表明,该系统功能丰富、便于操作、成本低、安装与维护方便,具有较好的推广和应用价值。

Aiming at current developing status of TTU at home and abroad, and on the basis of wide marketing investigation, an integrated design strategy of online monitoring for distribution transformers is proposed. The system is based on UPSD3334 single chip computer and GPRS communication technology. In accordance with acquisition principle for data of electric power distribution, and calculation method for electric parameters, the design of hardware system, and the development of the software for distribution transformer detection terminal and main station monitoring center management are implemented. In addition, the design of anti-interference for both hardware and software is conducted. The results of experiments indicate that the system offers rich functions, easy installation and operation and maintenance, low cost, and well worth to be propagated.
