ACOUSTIC ANALYSER OF SWARMING IMPULSE OF BEE FAMILIES Russian patent published in 2010 - IPC A01K47/00 

FIELD: agriculture.

SUBSTANCE: invention relates to bee keeping and is intended for use in practical work at individual and collective apiaries to analyse bee family condition in process of its development with determination of status extent. Analyser comprises external microphone 1, amplifier 2, band-pass filter 3, unit of automatic adjustment of amplification 4. Outlet of band-pass filter 3 is connected to two frequency channels : swarming status and working status of bee family. Swarming status channel comprises serially connected double-cascade serial-resonant gyrator narrowband amplifier 5, the first detector 6, the first integrator 7. Channel of bee family working status comprises serially connected narrowband filter 8, the second detector 9, the second integrator 10. Outlets of the first and second integrators are connected to comparison unit 11, outlet of which via analogue-digital converter 12 is connected to digital liquid-crystal indicator 13.

EFFECT: invention makes it possible to improve validity of bee family swarming status determination, and also efficiency of bee keeper labour when determining conditions of bee families due to optimal ergonomic characteristics of analyser and simplicity of its use; to monitor dynamics of families development in process of their growth.
