METHOD FOR RADIO FREQUENCY IDENTIFICATION OF ANIMALS Russian patent published in 2020 - IPC E05B39/00 G06K19/00 

FIELD: agriculture.

SUBSTANCE: proposed method relates to agriculture, in particular to livestock sector, and can be used to obtain operational information on animals in order to generate control and reporting documentation. Disclosed method is realized using intelligent switch 1 and identifiers. Intelligent switch 1 comprises reader 2 and microcontroller 3. Reader 2 comprises synchronizer 4, master oscillator 5, synthesizer 6 of carrier frequencies, logical element AND7, duplexer 8, transceiving antenna 9, band-pass filter 10 and phase detector 11. Each identifier comprises microstrip transceiving antenna 12.i, unit 13.i accessibility to interdigitated transducer, narrow-band filter 14.i, amplitude detector 15.i, switches 16.i and 17.i, piezo-crystal 18.i, electrodes 19.i, tires 20.i and 21.i, set 22.i of reflectors (i = 1, 2, n).

EFFECT: high reliability of reading individual codes simultaneously from several animals in a radio sounding area, as part of a common flock, by successively in time of their radio request.
