Description
~0~232 The present invention relates to an information sign for use on airport runways or taxiways, these being used to provide information to aircra*t captains or to ~ehicle drivers.
Fixed or unchanging information is provided to aircraft captains or to the drivers of vehicles, using the signs that have been generally known up to now, when said information did not necessarily apply to one individual aircraft or vehicle.
Information of this kind is necessary, for example, to guide an aircraft or a vehicle on a pre-set taxiing route and is usually imparted by means of lighting systems and with the additional help of radio voice traffic between ground personnel and the aircraft captain or the vehicle driver in question. When this is done, there is insufficient operating safety in the case of poor weather, when lighting systems fail, or if voice radio traffic nets are overloaded.
For this reason, it is the task of the present invention to increase operating safety and radio traffic utilization in the ground manoeuvring area. According to the present invention, this task has been solved by using an information sign whose indicating surface incorporates changeable aircraft or vehicle-specific sym~olism to provide information concerning a runway or taxiing route that has been assigned to an aircraft or vehicle, and in that a control unit that can be controlled from a central computer is provided to display the symbols.
Developments of the present invention are set out in the sub-claims 2 to 17.
In an advantageous manner, the information signs make it possible to providP current taxiing-route information to aircraft captains or vehicle drivers in the area of the runway, the taxi routes, and oP the apron on the airfield. Stop and go information (traffic signal function), directional information, information ~i9~32 concerning the flight number or the identification number for the addr~ssee, as well as special information in the form of text or symbols can ~e imparted. This results in a significantly decrease of voice radio traffic that is used in managing taxiing traffic. In addition, the signs can be used as a secondary source of in~ormation in the event that some areas of the taxiway lighting system (e.g., stop bars) become unserviceable. It is also advantageous that, in order to achieve simpler installation, the energy that is required can be taken from the lighting system, or can be provided by solar or wind generators. Data transmission to the changeable signs can take place via separate copper or fibre optic lines, a data bus, by radio, or by way of existing cables used for the lighting systems, or by other systems.
The drawings shows one embodiment according to the present invention, and these show the following:
igure 1: a taxiing management system using mid-line lighting and a plurality of inEormation signs;
Figure 2: a block circuit diagram of a circuit for supplying and operating the structural elements of the taxiing guidance system shown in figure l;
Figure 30 a block circuit diagram of a circuit that has been modified compared to the circuit arrangement shown in figure 2~
Figure 1 shows ths management of taxiing traffic with the help of a mid-line lighting system and a number of in~ormation signs 1.
The information signs, which can incorporate either optical or mechanical display elements to represent the information, can be used as separate aids as well as in conjunction with lighting systams 2 and stop signal markers 3, in the form of redundant aids.
Fixed or unchanging information is provided to aircraft captains or to the drivers of vehicles, using the signs that have been generally known up to now, when said information did not necessarily apply to one individual aircraft or vehicle.
Information of this kind is necessary, for example, to guide an aircraft or a vehicle on a pre-set taxiing route and is usually imparted by means of lighting systems and with the additional help of radio voice traffic between ground personnel and the aircraft captain or the vehicle driver in question.

Data transmission to the changeable signs can take place via separate copper or fibre optic lines, a data bus, by radio, or by way of existing cables used for the lighting systems, or by other systems.
The drawings shows one embodiment according to the present invention, and these show the following:
igure 1: a taxiing management system using mid-line lighting and a plurality of inEormation signs;
Figure 2: a block circuit diagram of a circuit for supplying and operating the structural elements of the taxiing guidance system shown in figure l;
Figure 30 a block circuit diagram of a circuit that has been modified compared to the circuit arrangement shown in figure 2~
Figure 1 shows ths management of taxiing traffic with the help of a mid-line lighting system and a number of in~ormation signs 1.
The information signs, which can incorporate either optical or mechanical display elements to represent the information, can be used as separate aids as well as in conjunction with lighting systams 2 and stop signal markers 3, in the form of redundant aids.
Variable-sign signal data devices can be used as information signs, these being of the sort described in DE 31 28 329 Al. In these devices, raster panels form the indicatsr panels on which changeable aircraft-specific or vehicle-specific symbols that can be changed as desired are visible on the light-emitting surfaces of fibre optic conductors that are visible through the front side of the raster panel.
It is also possible to use information signs, the displays of which can be changed by flat ~laps that can be repositioned by a mechanical drive system, as are used, for example, on the information boards sPen in airports or railway stations.
Mid-line lighting systems for airports are generally known and are described, for example, in the brochure issued by AEG-TELEFUNXEN V22.8.5004/0576, dated 1976, Befeuerunasanlage fur den Flughafen Berlin-Tegel [Lighting System for the Berlin-Tegel Airport].
Using the information signs 1, an aircraft captain or the driver of a vehicle that is towing an aircraft can be provided with directional, stop and/or go information in a visible way. It is also possible to impart aircraft or vehicle-specific identification information as well as special information.
Th information signs 1 can be supplied with electrical energy from an existing lighting system, regardless of its operating status, from solar generators, or from wind generators that us~
either natural wind or else the efflux from aircraft, and/or by means of batteries.
In an ad~antageous manner, the information signs can incorporate their own operating-sequence controllers (see DE 31 28 329 Al) that can be connected, for example, to internal or external sen~ors. These sensors pick up positional and/or identification 2~9232 data of an aircraft or vehicle, and this is then processed independently in the control unit of the information sign 1, and can optionally be transmitted to a central computer.
This information transPer can be accomplished by means of the existing cable of a lighting system 2 or with the help of an independent data transmission system, preferably a radio data transmission system. Provision is also made such that a plurality of information signs l can be connected to form a system that receives information for the individual information signs 1 from a central computer unit.
The circuit arrangement that is shown in figure 2 shows a lighting system 2 (mid-line lighting system), which works in conjunction with structural elements used to supply and operate two information signs 1 and two stop signal markers 3. The lighting system 2 incorporates, for example, a total of three underground lights 4, each of which is arranged in the secondary circuit of a transformer 5. The primary windings of thes~
transformers 5 are connected, together with a computer unit 6, in series on the output terminals of a constant current regulator 7.
The computer unit 6 is controlled by a central computer 10 that also controls the controllable control units 18 for the information signs. In each instance, a symbol display 19 and a text display 20 of the information signs and a stop/go indicator unit 21 (not shown herein) of khe stop signal marker 3 (not shown herein~ are associated with the control units ~8.
As can be seen from figure 2, the power supply unit 15 for the structural elements of the upper in~ormation sign is supplied with electrical energy from a mains line 22. In contrast to this, the lower part of figure 2 shows another possibility, namely, that the structural elements ~or the second (lower~
indicator sign can be supplied with electrical energy from the 2~9232 lighting system 2, regardless of its operating status. To this end, the primary winding of another transformer 8 is connected in series with the primary windings of the transformers 5 and the secondary winding of this transformer 8 is connected to the energy supply inputs of the energy supply unit 15 and of the controllable control unit 18 for the second information sign.
Other possibilities for supplying energy are shown in ~igure 3, namely, the supply of the power supply unit 15 with the help of a solar generator 17 and~or a wind generator 16 and/or a battery 9.
In this connection, the wind generator 16 can use natural wind or the efflux of aircraft in order to generate the electrical energy.
The controllable control units 18 that are shown in figures 2 and 3 are provided with additional inputs that are connected to the output of an internal and/or external sensor 11. These sensors 11 pick up the position and/or identification data of an aircraft or vehicle and these are then passed to the control unit 18, in which these data are processed automatically. It is also possible to send these data to the central computer 10, which then passes the information through the ccntrol units 18 to a plurality of information signs 1 or stop signal markers 3 that are connected together to form a system. The transfer of information can be accomplished, for example, by means of existing cable for the lighting system 2, or by way of an independent data transmission system or a radio data transmission system, by means of the components 14.
It is also possible to use information signs, the displays of which can be changed by flat ~laps that can be repositioned by a mechanical drive system, as are used, for example, on the information boards sPen in airports or railway stations.
