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 noise), amplification, filtration in various frequency bands, detection and comparison of produced signals by means of comparators. 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. ^ 2 cl, 14 dwg |
