Abstract
The invention concerns a device for remote reading of states, comprising a communication network (1), a plurality of peripherals (31 to 33) each of which adopts an instantaneous state (STAT—1 to STAT—3), and a controller (2) periodically scanning said peripherals (31 to 33) to read therefrom the instantaneous state (STAT—1 to STAT—3). The invention is characterized in that the communication network (1) electromagnetically connects the peripherals (31 to 33) to the controller (2), and said peripherals (31 to 33) are supplied with electrical energy via said communication network (1). The invention is useful for managing calls in lifts by means of peripherals not provided with any galvanic connection and with any individual power source.
