FIELD: electric engineering.
SUBSTANCE: method is based upon detection of non-healthy animals inside area of heating and forming of control signal. Preset threshold signal informing on absence of animal inside area of heating is formed. Then additional signal is formed which corresponds to moment of time at which animal leaves area of heating. Period of time is calculated inside which all the animals leave area of heating and when that period of time is over, the control signal is compared with preset one. Control signal informing on presence of animals inside area of heating is formed according to the result of comparison. The control signal is used for signaling on presence of non-healthy animal inside area of heating. Device has area of heating provided with brooder house, animal presence detector, power supply and relay. Output of power supply is connected with first power input of relay. Device also has signal lamp, first amplifier, first comparison circuit, first preset device, time counter, pulse former, first and second differentiating circuits, first controlled switch, second comparison circuit, second preset device, second controlled switch. Output of animal presence detector is connected with first inputs of first comparison circuit and first controlled switch through first amplifier. Output of controlled switch is connected to first input of second comparison circuit which has second input connected with output of second preset device. Output of second comparison circuit is connected to connection point of output of relay and output of second controlled switch. First input of controlled switch is connected with output of power supply. Output of first comparison circuit is connected with second control input of second controlled switch and with first input of time counted through first differentiating circuit. Output of time counter is connected with second control input of first control switch through pulse former and with null second input of time counter through second differentiating circuit. Output of relay is connected with signal lamp.
EFFECT: improved efficiency of information supply on presence of non-healthy animals inside area of heating.
