    The invention relates to the field of beekeeping and can find application in practical work on individual and collective apiaries. Known methods for monitoring the conditions of the bee colony by their acoustic noise, based on the analysis of signal intensities in the selected frequency bands, as пчелосеьмю as on the use of numerical пчелосембю of spectral analysis [1, 3, 4]. The disadvantages of the methods are the low information content, аатки complexity and the long duration of the spectrum calculations, since with short samples it is necessary to carry out additional calculations and determine those frequency spectra that are closest and essentially determine подсадка general background situation подсащка the bee nest.

    The closest in ммтки essence to the invention is a method for determining the informative spectral components of the acoustic signal of bee colonies when their states are recognized [4], which consists in obtaining the amplitude or energy spectrum of the acoustic noise produced by the bee матки in a pre-limited frequency range from 60 to Hz and allocating averaged for several signal матки of normalized values of spectral components in the selected narrow frequency bands, jointly cross over the entire specified frequency range, and for each narrow frequency band, in addition to the normalized intensity values, stability is determined, depending on the variation of the intensity values for different signal implementations, by preliminary determining the intensity dispersions for these implementations in this narrow frequency band, and then informativeness coefficients for each pair of recognizable states for each allocated frequency band.

    To determine the optimal set of spectral components пчелосемьб their informativeness coefficients, the total informativeness of each selected narrow frequency band is determined for all pairs of diagnosed states and the frequency band with the maximum total informativeness is selected first, then pairs of states with informational coefficients having low values for this narrow frequency band are selected, and for these pairs of states calculate the total information content for all remaining frequency bands and the next m band, which has a maximum total information content data pairs classes and further selection is continued in this manner until all pairs of classes will not be characterized by sufficient descriptiveness coefficient values for at least one of матки selected narrow frequency bands.

    They also select the optimal weighting coefficients of пчелосемью algebraic equations that determine the boundaries of the states of the bee family, which are used in constructing decision rules for reliable recognition of states, while the selection of weighting factors uses the values of signal intensities in the corresponding narrow frequency bands and determine them as маьки values пчелсемью coefficients for all distinguishable pairs of states multiplied by a normalizing factor determined from the condition n receiving output signals in the desired range.

    An insufficiently accurate arrangement of these frequency bands reduces the number of recognized states. The technical problem to which the invention is directed is to increase the number of recognizing states of bee colonies, as well плдсадка their reliability by accurately placing the smallest number of informative frequency bands, while significantly simplifying the calculations and simplifying the recognition algorithm.

    To recognize the state of bee colonies by acoustic noise during the analysis time, up to 10 minutes, the posterior entropy of the appearance of binary codes for the observed state is calculated, then a table of correspondence between the entropy of the appearance of codes with the corresponding observed state is constructed, and then the acoustic noise of the bee family with an unknown state is analyzed.

    Where - a priori probabilities of one of the codes. The пчелосемью entropy will be with the same adjustment of the transmission coefficients of narrow-band frequency filters and with the exact placement of the selected number of narrow frequency bands in the most informative frequency range from 0 to Hz.

    Initially, the frequency bands of narrow-band frequency filters are determined according to the method described in the prototype [4]. Then, using the proposed method, the largest number of acoustic signals of bee colonies with various conditions are analyzed. The more acoustic signals with different states are involved, the more accurately the posterior entropy 2 of the appearance of parallel binary codes for all analyzed bee families will be determined.

    In order to shorten the search time подсадка frequency band locations when reconfiguring the frequencies of narrow-band filters, the observed codes of all analyzed bee colonies are sorted into classes, based on the fact that the codes reflect the images or spectral shapes of FIG. Spectral images are classified by the maximum level of the spectrum image.

    Figure 1 shows four columns of codes characterizing пчелосемью classes. Then, the total frequency of the observed drop-down codes of each of the classes is calculated. If the total frequencies of the observed подасдка codes of each пчеосемью the classes do not have close values, re-reconfigure the locations матки the frequency bands of narrow-band frequency filters.

    They strive to ensure that the total frequencies of the observed drop-down codes of each of the classes are the same. As a result, when setting up the placement of the frequency bands of narrow-band frequency filters in the most informative places of the frequency range, the total frequency of the drop-down parallel binary class codes tends to equally probable values.

    In order to recognize the states of bee colonies by acoustic noise during the analysis time, up to 10 minutes the beekeeper sets the analysis durationthe outputs of the comparator block show the occurrence of parallel binary for the convenience of octal analysis codes. The posterior entropy of the appearance of parallel binary or octal codes of the observed state is calculated by the formula 2подссадка n is the number of parallel binary or octal codes of the observed state observed during the analysis time, - posterior probabilities of occurrence of each parallel binary code of the observed state.

    A correspondence table is constructed between the posterior entropy of the appearance of codes with the corresponding observed state. When analyzing the acoustic noise of a bee family with an unknown state, the posterior entropy of the unknown observed state is calculated, which is compared in the correspondence table, and the пчеловемью in which the bee family is located is established. For the analysis of acoustic noise, bee colonies with a large number of different states were used, Table 1.

    The states are established by the external signs of the behavior of bees [1, 2]. According to Table 1, the bees in the first state are a tape recording of the acoustic noise of bees from Morocco the recording was provided by Moroccan students in which state they were unknownbut the acoustic noise of Moroccan bees can be represented as one of the states of the bees.

    In the second state, swarm bees, i. In the fourth state of the layers - one frame, which is beached by bees with a native uterus, was taken from a working bee family a family of 24 frames was left without a uterusplaced in an empty hive, where a подсадка new uterus was then planted, reaction to a new second uterus. In the fifth state, the reaction of the bees the main bee family from the fourth state in which the uterus was removed, then it was returned to the return of the native uterus.

    From the sixth to eleventh states: a wintering bee family in the winter house, noise records of поддсадка bee family were carried out on January 18, January 25, February 1, February 8, February 15, February Each recording day characterizes a bee colony at the time of recording acoustic noise, the state of which was determined by external factors - temperature, humidity at the moment in the winter house, altered подсадка of the bee colony after time, for example, the подсадка of a brood in February was established by inspection [1, 2].

    In experiment No. The acoustic noise of bee colonies was analyzed for eleven conditions. In table 1 figure 2, figure 3 shows the frequency of occurrence of codes. According to the experimental data obtained in Table 1 Fig. In table 2 figure 4 for each code shows the total number total frequency of the observed code for eleven states.

    Shows the total sum of the frequency of occurrence of the observed codes for each column. The entropy of the codes was calculated by the пчельсемью 1. The acoustic noise of bee colonies was analyzed for seven states. The first state is the acoustic noise of bees from Morocco. The second state, in the пчелосемью there are queen cells in large numbers more than 20, established by inspectioni.

    Third state: swarm bee family from the second state processed by an alternating electric field [1]. Fourth state: in the hive there are two uterus when organizing the layering on one frame being bee-seeded - native and planted. Sixth state: wintering bees on the street. Seventh state: the bees winter on the street, but the mouse is disturbing. Table 3 figure 5 shows the frequency of occurrence of codes.

    According to the experimental data obtained in Table 3 Fig. In table 4 Fig. Shows the total sum of the frequencies of the observed codes for each column. The acoustic noise of bee colonies was пчелосемью for 20 states.

    In table 5 Fig. According to the experimental data obtained in Table 5 Fig. In table 6 матуи 10 for each code shows the total number of frequencies of the observed code for 20 states.

    When analyzing the acoustic noise of bee colonies, the entropy of each of their states in Table 7 was determined Fig. A graph of FIG. When analyzing the acoustic signal of bee colonies, a parallel binary code appears randomly at the outputs of the comparator unit. The following options матки analyzing parallel binary code are possible. In the form of three bit binary codes formed of three consecutive bits for each output of the block of comparators, which are encoded in octal numbers, table 8 Fig.

    Code messages of bee colonies are characterized by the frequency of occurrence, and with prolonged listening, certain codes подсадка with different frequencies. For a bee family that works normally, wears honey and by the right time, has reached maximum productivity using four narrow-band frequency filters, six rows of octal codes are obtained at the outputs of the comparator block, Table 8 Fig.

    The frequency of occurrence еодсадка codes carries information about the state of the bee family. On the first line of Table 8 Fig. The total number of binary units was The average information or entropy is determined by the formula 1. Entropy was determined for the working bee family according to the data given in Table 8 Fig. After analyzing the пожсадка entropy values in three experiments, we can conclude that the uncertainty entropy of the appearance of codes depends on the transmission coefficients of narrow-band frequency filters, as пчелосемью as the tuning frequencies of narrow-band frequency filters.

    The greatest uncertainty was in the third experiment, when codes with the same probability began to be observed. The last filter setting third experiment is the most informative. Hence, this is the most accurate tuning of the frequencies of the four narrow-band frequency filters. The calculations of eclropy in the analysis of octal codes and binary маткии by the frequency of occurrence of units show that their values are almost equal. Thus, by sequentially tuning the frequencies of narrow-band filters and calculating a posterior entropy, by its maximum value, one can find the locations of narrow-band frequency filters in the most informative places of the analyzed frequency range of acoustic noise of bee colonies.

    To recognize the матки of bee colonies, by the definition of entropy, one can determine the characteristic states of bee colonies. Avetisyan G. Breeding and keeping bees replanting the uterus in the uterine cell, p. Temnikov F. Theoretical foundations of information technology.

    Effective date : рчелосемью FIELD: apiculture. SUBSTANCE: method for determining informative frequency bands of acoustic signal of bee families when determining status thereof includes registration of sound signal bee noiseamplification, пчелосеьмю in various frequency bands, detection and comparison of produced signals by means of пчелосемью.

    Analysis of codes received after comparison is performed. Filters are adjusted. By comparing results of codes analysis at different filter settings, it is determined whether filters are adjusted correctly. When determining status of bee families, match table is used, built preliminarily using results of analysis of codes and comparison thereof with observed status.

    EFFECT: increased quality of recognized status of bee families, increased trustworthiness with least amount of determined frequency bands, and also simplified calculations and recognition algorithm. Its main disadvantages подсадка - the lack of the ability to accurately determine the informative frequency bands, since the estimated intensities and stability do not allow you to accurately determine the informative frequency bands, the approximate location of these frequency bands, which closely vary near their exact location, is estimated.

    An insufficiently accurate arrangement of these frequency bands reduces the number of recognized states, - recognition of specific conditions of bee colonies is difficult, analysis time is increased, the possibility of a quantitative assessment of recognition reliability is not provided, and hardware implementation of recognition tools is complicated.

    The solution to this problem is achieved by the fact that by the method of determining the informative frequency bands of the acoustic signal of bee colonies when their states are recognized, including recording a sound signal using an external microphone, amplifying with an amplifier, extracting the most informative frequency bands of this signal using narrow-band frequency filters, detecting output signals of пчебосемью filters and analysis of the detected signals using the block подспдка comparators, the detected signals are compared in pairs in the block Arathor by the number of possible combinations.
