2. Description of the Related Art FIG. 5 shows, for example, JP-A-9-251599.
It is a conceptual diagram which shows the conventional airport monitoring system shown by the publication. In FIG. 5, reference numeral 1 denotes a plurality of bar code readers installed in an airport for reading data of bar code plates for identifying an aircraft and a work vehicle.
1h is an individual bar code reader. 2 is a transmission device for transmitting the data read by the barcode reader 1;
Is an entry restriction display device which is connected to the transmission device 2 and displays the entry restriction of the work vehicle, and two devices 3a and 3b are shown. Reference numeral 4 edits the data transmitted through the transmission device 2, automatically wirelessly transmits spot control information for the aircraft based on the edited data, and displays the access restriction of the work vehicle on the access restriction display device 3. It is a centralized monitoring device that performs control. 5 is an aircraft
a-5c have shown each aircraft. 6 is a work vehicle, 6
a and 6b are individual work vehicles.

Next, the operation will be described. The data read when the aircraft 5 and the work vehicle 6 pass through the barcode readers 1a ... 1h are transmitted to the centralized monitoring device 4 through the transmission device 2. The centralized monitoring device 4 collectively edits the information of the aircraft 5 and the work vehicle 6 and performs a process of linking with the most efficient spot information to determine the spot control and the permission to run the taxiway. This information is automatically transmitted to the corresponding aircraft 5 via wireless communication. Further, it is determined whether the work vehicle 6 interferes with the smooth operation of the aircraft 5. This judgment information is displayed on the entry restriction display device 3 to prevent the work vehicle 6 from inadvertently entering.

[0004]

Since the conventional airport traffic monitoring system is configured as described above, the spot control and the taxiway travel permission for the aircraft 5 are performed only by wireless communication. It is difficult to accurately tell the pilot the route to the runway. In addition, there is a problem in that the barcode data may not be read due to stains on the barcode plate or a reduction in visibility due to rain, snow, fog, or the like.

The present invention has been made to solve the above problems, and accurately conveys the route from the satellite to the runway to the pilot, and is highly resistant to dirt and changes in weather conditions and highly reliable. The purpose is to obtain an airport traffic monitoring system.
