Supervision and control of airport lighting and ground movements
First Claim
1. A monitoring and control system for an airfield lighting arrangement, including light units installable at light unit locations, wherein each light unit is connected to an electronic unit, said electronic unit comprising is regulator, a monitoring unit and a modem, for power supply to the light unit, and for monitoring the operation of the light unit, each light unit being individually addressable from a control central for the airfield, the communication between the light units and the control central being carried over existing power cables to the light units, each electronic unit location includes an associated address code means, said address code means including permanent magnets, the north and south pole orientation of which gives a unique digital address providing an address unique for each said location and each electronic unit includes address code receiving means connectable with said address code means including magneto-sensitive elements for sensing the north and south pole orientation of the magnets and associating said unique address with said electronic unit when said electronic unit is put in place at said location.

Abstract
In an arrangement for supervising and controlling field light units (20) at an airport, a regulator provided with a monitoring unit for power supply and for monitoring the light units is arranged individually for each light unit (18,20) to regulate the light intensity of the light units and to receive information as to their operational status. In a preferred embodiment, each light unit comprises two separate light sources that can be alternately and separately connected into circuit in case of failure to either of the light sources. Each light unit is provided with an electronic unit including a regulator, monitoring unit, and modem for power supply to the light unit and for monitoring the operation of the light unit. Each light unit is individually addressable from a control central for the airport. A ground traffic control system can be integrated into the field lighting system by connecting suitable presence detectors to the system.
