FIELD: automated information collecting systems with time demultiplexing of channels used to collect and timely process data received from measurement transducers of radiation contamination of atmosphere. SUBSTANCE: invention is meant for design of system ensuring absence of resistance coupling of transmitters noninterrogated at given moment with electric circuits of units for conversion and transmission of measurement results, isolation of units determining sequence and periodicity of interrogation of transmitters from units controlling process of data conversion and transmission and high reliability of system operated unattended. System to collect, convert and process measurement information has k groups of n transmitters, k commutators, k units controlling commutator, k analog-to- digital converters, two channels for communication with peripheral equipment, input/output channel and central control and processing device. EFFECT: increased functional reliability of system. 1 dwg
