STUDY AND DEVELOPMENT OF A SELECTIVE MONITORING SYSTEM

Abstract

To reduce the load on data transmitting and processing equipment-- and thereby reduce the size and power requirements of such equipment in space vehicles--methods of selecting only the significant portions of data from transducers were investigated, and a six-channel laboratory model of a selective monitoring system was built and tested. Two principles of data selection were studied: (1) selection based on departure of a process variable from the steady state, and (2) excursion of a process variable beyond predetermined limits. Selection data while in the analog state--as taken directly from the transducers--and selection data after conversion to digital code were studied. The laboratory model demonstrates selective monitoring of analog data after conversion to digital code and uses as a selection criterion either departure from the steady state or excursion beyond limits. A program for applying the knowledge gained by the study and the principles demonstrated by the model to space-vehicle equipment is described.
