Ground marking device and process and installation comprising same
First Claim
1. Marking device comprising a light source and a processing circuit to control lighting of said light source, and comprising:
- optic communication means having at least one optic emitter connected to the processing circuit, and detection means to detect the presence, movement or passage of an object, said detection device being connected to the processing circuit to control the optic communication means according to signals supplied by said detection means, said at least one optic emitter emitting an optic communication signals of lighting command to at least one other marking device when a detection signal is supplied to said processing circuit.

Abstract
The marking device comprises a light source and a processing circuit to control lighting of said light source. Said device comprises an optic communication having at least one optic emitter and/or one optic receiver connected to the processing circuit. A detector detects the presence, movement or passage of an object. Said detector is connected to the processing circuit to control the optic communication according to signals supplied by said detector. A marking installation comprises marking devices arranged for example on a section of runway for an airport for guiding aircraft, or on a section of road to perform road signalling. The marking process enables the marking devices to be switched on by optic means according to detections.

26. Marking process comprising:
-
a switch-on step of a light source commanded by receipt of a control light signal emitted by a previous marking device, a detection step to detect the passage or presence of an object intended to be detected, a communication step of a detection light signal or of a switch-on command to at least one following marking device, and a step commanding end of lighting of said light source when detection is terminated.
