SYSTEM OF REMOTE RADIATION CONTROL(VARIANTS) Russian patent published in 2007 - IPC G01T1/167 

FIELD: the proposed invention refers to means of remote control of radiation state of an object and may be used for air radiation control in the buildings of a controlled zone and in the ventilating systems of atomic power stations.

SUBSTANCE: The aim of the invention is creation of a system of remote air radiation control which allows to simplify periodic control and exclude possibility of errors in the results of measurements at changing conditions of delivery of controlled mediums to detection blocks. The proposed system of remote air radiation control has detection blocks, distributing boxes and controller-calculators including: a microcomputer, sources of feeding of the detection blocks, converters of the detector signal and arrangements for input-output of information along the information channel, one for each detection block; an operator's panel with a personal computer and with means of reflection of information, a block of collection, primary processing and analysis of information, autonomous blocks of uninterrupted feeding, pipe-lines with closing-regulating valves of manual control, filters and flow-measuring apparatus for direction of continuously controlled mediums with prescribed consumption to detection blocks, pipe-lines with remotely controlled closing valves according to periodically controlled mediums combined at the exit of the valves for delivery of controlled medium with prescribed consumption through the closing-regulating valve of manual control, a filter and a flow-measuring device on a common detection block, two gas blowers, two closing valves of the gas blowers with remote control, a discharge sensor at the entry of the gas blowers, a valves control block, a gas blowers control block and a gas blowers switching block consisting of two arrangements of switching of electric drives. In the additional modification of the proposed scheme it additionally includes as component the second block of collection, primary processing and analysis of information.

EFFECT: simplifies remote periodic control and excludes possibility of errors in the results of measurement.
