Abstract:
A lighting system, which may be used, for example, as an airport lighting system, as a street lighting system, as an obstruction warning light, as an illuminated sign, as a warning light, or as a signal light or the like. The lighting system includes a device for monitoring and controlling its light sources or groups of light sources. The light sources have at least one respective lighting unit, with which a transceiver device is associated. The transceiver device includes a microcontroller and is, via a power supply line and a router, connected to a central station. The central station includes a transceiver part and a control computer and supplies the transceiver device with control commands. To ensure that larger lighting systems can be safely operated with a comparatively low expenditure, the microcontrollers of each lighting unit are components of a decentralized control device. The decentralized control device includes application-specific components, such as switching components, monitoring components, and adjustment components. Therein, the larger lighting systems include a plurality of light sources that are to be controlled and regulated on an individual basis. The transceiver device is structured as a module part disposed on a sickle-shaped printed circuit board and disposed next to the lighting unit.
Abstract:
An airport surface movement guidance and control system (SMGCS) involving detection, integrated processing and graphical display of the relevant, in particular the safety-relevant, positions and movements of aircraft, and optionally, vehicles, on airside (runway, taxiways, apron) and in the relevant airport airspace. At least one radar detects the positions and movements between airborne and parked positions of the aircraft. The relevant data are displayed after data concentration on the monitor of at least one controller station in graphical form and/or letter or number form. As a result, the operational management of the surface movement can be planned and executed from the at least one controller station by means of solely the SMGC system.
