摘　　要：随着市场经济的发展,用户对供电质量和供电可靠性的要求也越来越高,配电变压器是配电网的重要组成部分,其自动化程度的高低,直接反映了配电自动化的水平。本文介绍了一种以TI公司的新型16位低功耗Flash型单片机MSP430F5438和以太网芯片W5100为核心的新型多功能配变监测终端(TTU),通过以太网通讯,实现远程数据传输,以执行配电网运行参数与状态监控。着重论述了此系统的硬件组成、软件流程、数据采集以及实现以太网通信的方法,通过以太网通讯可方便地对终端进行操作。With the development of market economy, consumers put forward higher requirements about power quality and supply reliability. Since distribution transformer is the most important electric power equipment in the distribution network, whose degree of automation will directly reflect the level of the distribution automation. This paper introduces a new muhifunction transformer terminal unit based on a MSP430F5438 ,which is a 16 bit low power consumption flash type microcontroller and an Ethernet chip W5100. This terminal uses the technique of the Ethernet communication to realize remote data transmission and monitor the distribution network parameter and status. This paper also emphasizes on the hardware components, software flow, data collection of this terminal and the methods of Ethernet communication which makes it easier to operate the terminal via Ethernet communication.
