LONG DISTANCE SIGNAL TRANSMISSION SYSTEM SUITABLE FOR THE CONVERTING CAPACITY OF A COMMERCIAL VOLTAGE-CURRENT CONVERTER

摘要

PURPOSE: A long distance signal transmission system suitable for the converting capacity of a commercial voltage-current converter is provided to operate a long distance signal transmission system using a common voltage-current converter.;CONSTITUTION: One or more sensors(100) transmit a first measurement signal to a measurement system through a signal line after the measurement of more than one kinds of data(300). A pre-processing unit(400) changes the measurement signal of the first voltage range of each sensor to the second voltage range. A voltage-current converter(200) changes a converted measurement signal of the second voltage range to a current measurement signal corresponding to the voltage of the measurement signal.;COPYRIGHT KIPO 2010
