Багатоканальна високоточна система збирання даних на основі високопродуктивних АЦП із ваговою надлишковістю

Abstract

Existing methods of constructing multi-channel data acquisition systems and their characteristics were analyzed, data systems with weight redundancy and their applications for improving the static characteristics of elements of multi-channel systems were described. Self-calibrating process of level’s weights of analog-digital converters is analyzed. The structure of the system was designed and its algorithm was described. Static and dynamic characteristics of the elements were reasonably improved because of which were improved characteristics of the system as a whole. The recommendations for the practical realization of analog units that can be used in the system in order to improve their performance were described. Program for modeling working process of the system is designed and tested. Economical expediency of implementation of the system is proved.
