Abstract
A control system includes a plurality of subscriber devices of a communications network, these subscriber devices communicating with one another by optical signals. A subscriber device includes two opposing faces, an optical shutter controllable between an at least partially transparent state and an opaque state, the optical shutter traversing a part of the subscriber device between the two opposing faces; a control circuit configured for controlling the controllable optical shutter; an optical signal emitter on a first of the two opposing faces, disposed in such a manner as to allow the emission of optical signals toward a first neighboring subscriber device; and an optical signal receiver on a second of the two opposing faces, disposed in such a manner as to allow optical signals to be received that originate from a second neighboring subscriber device.
