FIELD: radio engineering, communication.SUBSTANCE: system comprises a search unit, 1-N search labels and a radio link, wherein the search unit comprises a keyboard with 1-N keys, a microcontroller, a modulator, a direction finder and an acoustic channel, and the search label comprises a demodulator, an activator with a HF generator, an emitter and a power supply. The microcontroller includes custom software in which 1-N code transfers, corresponding to the number of search labels, are recorded, and the demodulator of each search label is pre-tuned to its code transfer.EFFECT: enabling search of the required label from a plurality of labels attached to a search object.4 cl, 1 dwg |
