MULTI-CHANNEL SIGNAL ACQUISITION APPARATUS AND METHOD WITH HIGH RELIABILITY

摘要

The present invention relates to a high reliability multi-channel signal acquisition device and method, and more particularly, to a high reliability multi-channel signal acquisition device and method that can be applied to satellite launchers, satellites, aircraft, etc. requiring high reliability and low weight design. will be. A high reliability multi-channel signal acquisition device according to the present invention includes a multiplexer for selecting one of a plurality of electrical signals, three programmable amplifiers connected in parallel to each other to amplify the electrical signal selected from the multiplexer, and each of the three programmable amplifiers. Compares the output values of each of the three AD converters and the three AD converters for converting the amplified signal into a digital signal, and controls the operation of the multiplexer, the three programmable amplifiers, and the three AD converters. It is characterized by consisting of a controller for.; Multi-Channel, Signal Acquisition, High Reliability, AD Converters, Amplifiers
