CONSUMPTION AND LEAKAGE CONTROL SYSTEM OF HOUSEHOLD GAS IN BLOCKS OF FLATS Russian patent published in 2013 - IPC G08B17/10 

FIELD: instrument making.

SUBSTANCE: system includes: generators, apartment gas contamination sensors, gas flow counter, gas supply shut-off valves, gas contamination level comparing unit with allowable value, pulse counters, pulse frequency converters into analogue signal, alarm units; logical components 'OR'; sources of reference voltage of allowable gas contamination level; gas contamination sensors for entrance hall, gas flow counter, gas supply shut-off valves, gas contamination level comparing unit with allowable value, sources of reference voltage of allowable gas contamination level, pulse counters, pulse frequency converters into analogue signal, alarm units; summing unit of total gas contamination of entrance hall, comparing units of total gas contamination levels, sources of reference voltage of total gas contamination, imbalance summing units, imbalance module selection units, evaluation units of current imbalance of gas flow, sources of reference voltage of allowable imbalance level, cellular modem, keys, delay lines, phase manipulator, amplifier and antenna.

EFFECT: increase of noise resistance and reception integrity of transmitted information by false signals suppression received via optional channels.
