Automatic control system of lights in a series circuit illumination plant, in particular lights for airport signalling
First Claim
1. In an automatic control system for the lights of an illumination plant in a series circuit, in particular for airport signalling lights, physically separated from the work circuit feeding said lights and galvanically separated from the latter, comprising:
- a computer;
several Main Stations each containing several Main Modules, each controlling several Remote Modules which check and act on a single airport light, each of said Main and Remote Modules comprising firmware boards;
a full duplex data transmission network linking said computer with said Main Stations;
the improvement including;
each Remote Module has externally two pairs of electric terminals of which one said pair is connected to the secondary of an insulating transformer making part of said work circuit and the other pair is connected to a light or a group of lights being controlled, said two pairs of electric terminals being connected to each other by electrical leads, wherein connected in series to one of the electrical leads is a coil which is magnetically coupled to a Hall sensor of the Remote Module; and
further including an electronic device with controlled conduction having two conducting terminals and a control terminal, each conducting terminal connected with one of said electric leads while the control terminal is connected to circuitry which connects said electronic device magnetically to internal circuitry of the Remote Module itself.
