the Study of an Electric Transmitter Based on the Real-time Ethernet

本文分析了实时以太网系统的优点,介绍了一种基于实时以太网多功能电量变送器的设计方法。该装置采用MSP430F149和AT89S58并行处理技术,通过以太网发送电流、电压、有功、无功等实时测量值,并且可根据设定限值实时监测被测系统的故障变化,从而提供部分的保护和控制功能。

The paper analyses advantages of Real-Time Ethernet system, introduces the frame of a multifunctional electric transmitter based on the Real-Time Ethernet. This device uses MSP430F149 and AT89S58 with its parallel-processing technique, and transmits real-time measured values of various electric quantities from Ethernet. It also can monitor fault of the monitored system according to predefined values and thereby provide partial protection and control ability.
