FIELD: agriculture.
SUBSTANCE: invention relates to the field of beekeeping and can be applied in practical work on individual and collective apiaries. In the first method of diagnostics of states of bee-families according to their acoustic noise during the analysis time up to 10 minutes, the acoustic signal is taken using a remote microphone and it is intensified with the preamplifier. With the help of n narrow-band frequency filters the preliminary selected most informative frequency bands of this signal are defined. The output signals of narrow-band filters are detected. In order to form images of the spectra, each voltage at the output of the detector is measured, the image of the spectrum is formed according to the measured values, according to which a square matrix n"г"×n"в" is created. Then, during the time of diagnostics, up to 10 minutes, N square matrices of binary digits with dimension n"г"×n"в" are successively obtained, which are sequentially converted into binary linear codes with dimension n2, using which the diagnostic matrix with dimension n2×N is formed. Then, by a voting method the linear code is set by which the conclusion is made on the state of the bee-family. In the second method for forming code messages the digitised voltage values are programmatically compared pairwise in all possible combinations. The codes with digit capacity of 
EFFECT: increased reliability of recognition of the state of bee-families is provided.
