FIELD: control devices.SUBSTANCE: invention relates to wireless devices for controlling reserves. Disclosed is passive receiver formed so that in wireless mode receive start-up signal with accompanying energy field of remote control system and to give signal on change of operating mode. Passive receiver is made so that to be powered by power field associated with start-up signal. Disclosed is functional module, connected to passive receiver and made so that to be powered by independent power source when functional module is in active mode. Functional module also is formed so that to receive signal on change of operating mode of passive receiver and change from inactive mode to active mode. Functional module consumes more energy from power supply in active mode than in inactive mode.EFFECT: technical result is longer battery life in control device reserves.28 cl, 8 dwg |
