摘要：
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 are obtained, coming to the input of the PC, which converts the incoming binary codes into octal or decimal. Then, the diagnostic matrix of binary six-bit or octal codes is created, or a diagram of state of the bee-family. The device of diagnostics of states of the bee-families according to their acoustic noise comprises a microphone, an amplifier, a power supply unit, a set of detectors of half-period average value, the set of band-pass filters, a microcontroller with ADC according to the number of narrow-band filters, the communication unit, the PC.EFFECT: increased reliability of recognition of the state of bee
