GAS LEAKAGE AUTOMATIC DETECTION AND CONTROL SYSTEM Russian patent published in 2018 - IPC G08B19/00 

FIELD: alarm system.

SUBSTANCE: invention relates to alarm systems that can produce sound or light signals. In the method, the automatic gas leakage detection and control system, including a detection unit, comprising a microcontroller with sensors of monitored parameters and a transmitter, an audible alarm device and an emergency valve associated with the microcontroller, as well as a detection unit, is provided with a sensor for monitoring the presence of odorant concentration, and a differential pressure sensor that is installed in the exhaust ventilation zone and is connected to the microcontroller, designed to calculate the concentration of controlled gases and odorant and compare it with the level of admissible concentrations of controlled gases for the output of the signal in the event of deviation from the permissible values.

EFFECT: technical result consists in increasing the reliability of information about the emergency situation.
