Abstract
Система предотвращения затопления помещения, включающая влагочувствительные датчики, включенные параллельно в электрическую цепь и размещенные в местах возможных протечек воды, и блок управления, связанный с электромагнитными запорными клапанами водоразборного трубопровода, отличающаяся тем, что электрическая цепь влагочувствительных датчиков дополнительно включает резистор заданного сопротивления R1 и электрически связана с блоком управления, выполненном в виде блока обработки сигналов, а также с дополнительным узлом сигнализации и дополнительным блоком питания указанных датчиков, меняющем полярность электрического тока с заданной частотой, причем блок обработки сигналов выполнен с возможностью замера величины сопротивления R2 указанной электрической цепи и передачи на узел сигнализации сигнала I1 о нарушении целостности системы в случае увеличения R2 на величину, большую контрольного значения Δ1, а также передачи двух сигналов - I1, поступающего на узел сигнализации, и сигнала I2, поступающего на электромагнитные запорные клапаны водоразборного трубопровода в случае снижения R2 на величину меньшую контрольного значения Δ2.A system for preventing flooding of a room, including moisture-sensitive sensors connected in parallel in an electric circuit and located in places of possible water leaks, and a control unit associated with electromagnetic shut-off valves of the water intake pipe, characterized in that the electric circuit of the moisture-sensitive sensors further includes a resistor of a given resistance R1 and electrically connected with the control unit, made in the form of a signal processing unit, as well as with an additional signaling unit and an additional power supply unit for these sensors, which changes the polarity of the electric current with a given frequency, and the signal processing unit is configured to measure the resistance value R2 of the specified electrical circuit and transmit to the signaling unit a signal I1 about the violation of the integrity of the system if R2 increases by an amount greater than the control Δ1 values, as well as the transmission of two signals - I1 received at the signaling unit, and signal I2 received at the electromagnetic shut-off valves of the water pipe in R2 uchae reduce an amount less than the reference value Δ2.
