FIELD: supervision over living conditions of bee families in bee-garden with use of analysis of frequency spectrum of audio signals uttered by bee families. SUBSTANCE: given automated system includes bee-garden controller, bee-master computer, analog-to-digital converter, sound intensifier with automatic gain control, blocking capacitor, modulating key, power on-off key, power supply unit of bee- garden, resistor, beehive controller, food allotting unit, beehive transceiver, sound intensifier, microphone, name unit, former, pause detector, counter, storage, unit reconstructing malfunctions, decoder, name encoder, name setting unit, initial setting unit. Automated system to control vital activity of bee families uses two wires only to record audio information from all beehives of bee-garden, they are also employed to supply electric power to controllers of all beehives. EFFECT: high timeliness and resolving power of system ensures high authenticity of identification of various states of bee families and efficiency of given system in bee-garden. 1 dwg
