DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air traffic control system, and more particularly to an air traffic control system for supporting a traffic control operation for distributing flight plan information.

[0002]

2. Description of the Related Art With the recent increase in air traffic by aircraft, the burden on air traffic controllers corresponding to the operation modes of many aircraft has become enormous. In the air traffic control business, the flight plan of the aircraft (flight plan) is to write the operation instructions to the aircraft on a strip sheet called a flight strip and distribute it to the controller.

[0003] Flight planning information in the air traffic control business is created so that one flight aircraft or one formation aircraft is always in one-to-one correspondence, and is automatically transmitted to a control seat in charge and displayed. The controller performs air traffic control operations in accordance with the distributed flight plan information, but may change a part of the flight plan information, such as a flight altitude and a flight route, depending on how crowded the aircraft is.

Conventionally, when a controller changes a part of flight plan information, the controller gives a change instruction wirelessly to the aircraft and manually writes the instruction contents on flight plan information (flight strip) printed on paper. However, when they confirmed that the aircraft was flying as instructed and when the instructions were completed, they had to fill out the flight strip by hand.

[0005] In recent years, electronic strip devices which have been electronically automated have been introduced, and the automatic distribution function of flight plan information has reduced the work load on the controller. In the case of issuing a handwritten operation, an operation called manual input from a keyboard, a mouse, a pen input device or the like still remains as an operation that replaces the conventional handwriting work, and depending on the input device used, there are operations that are more troublesome than the conventional handwriting work. . As described above, at present, the load on the controller has not been reduced for the input operation to the electronic strip device when the flight plan is changed.

As an example of a technique for processing such flight plan information, for example, an "air traffic control device" described in Japanese Utility Model Laid-Open No. 1-91700 is known.

This publication includes an information processing apparatus for processing flight plan information including radio frequency information with an aircraft, and transmits radio frequency information to the information processing apparatus a predetermined time before the arrival or departure time of the aircraft to be controlled. A technique for setting a wireless device to an operable state is described.

[0008]

The above-mentioned conventional air traffic control system requires an aircraft flight plan change instruction.
The input operation of the change instruction depends on manual input from any of a keyboard, a mouse, a pen input device, etc. ing.

In addition, there is a disadvantage that safety cannot be maintained because the user keeps his / her eyes away from the control display screen at the time of input operation.

It is an object of the present invention to provide an air traffic control system that automates the work associated with changing the flight plan of an aircraft and reduces the load on control operations by reducing the number of operation steps.

[0011]

An air traffic control system according to the present invention processes and stores flight information of an aircraft received from a radar, inputs change information for changing the operation of the aircraft, and stores the stored flight information and the input. The change information is compared with the changed information, and when they match, the change information is determined and highlighted for a predetermined time.

A plurality of input / display devices for inputting change instruction data for changing the operation of the aircraft and displaying an operation table of the aircraft; comparing the operation data of the aircraft received from a radar with the change instruction data; And an information processing device for determining the change instruction data if these data match, and causing the input display device to highlight the operation table determined for a predetermined time.

Further, the information processing apparatus receives and processes the operation data of the aircraft, outputs the data as operation information, inputs the change instruction data, outputs the instruction information, and uses the determined display information as the display data. A communication processing unit that outputs to the display device; a recording unit that records the operation information; a display information generation management unit that compares the operation information and the instruction information and outputs a result of the comparison as the display information. It is characterized by that.

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of an air traffic control system according to the present invention.

In the present embodiment shown in FIG. 1, an altitude information 23 from a secondary monitoring radar 20 located outside and a flight plan information 22 from a flight plan information processing system 21 are input, and information processing for processing these is performed. It comprises a device 1 and a plurality of display devices 2, 2a, 2b for inputting information on flight plan changes.

The flight plan information 22 from the flight plan information processing system 21 is received by the communication processing unit 3 of the information processing apparatus 1, and the flight plan information 8 processed by the communication processing unit 3 is recorded in the information recording unit 4. Is done. SSR (Secondar
y Surveillance Radar) or S
IF (Selective Identificati)
The altitude information 23 of the aircraft from the secondary monitoring radar 20 (on Feature) is transmitted to the communication processing unit 3 of the information processing apparatus 1.
And the altitude information 9 processed by the communication processing unit 3
Is recorded in the information recording unit 5.

The display information generation / management section 6 reads out the flight plan information 8 recorded in the information recording section 4 and the altitude information 9 recorded in the information recording section 5, and displays them as flight strips on the display devices 2, 2a, 2b. The display information 13 to be displayed is created. Further, the display information generation management unit 6 manages information transmitted and received between the information processing device 1 and the display devices 2, 2a, 2b.

The information processing device 1 and the display devices 2, 2a, 2b
All transmissions and receptions are performed via the communication processing unit 3.

On the other hand, an altitude change instruction for the aircraft, which is input by the controller from the input units 7, 7a, 7b of the display devices 2, 2a, 2b, is transmitted from the display device 2 as the instruction altitude information 14, for example, and is processed. Communication processing unit 3 of device 1
, And sent to the display information generation management unit 6 as the instruction altitude information 12 and managed.

The display information generation / management unit 6 includes the designated altitude information 1
2 and display information 13 indicating that altitude change is being instructed to the display device 2 to which the instruction altitude information 12 has been input. The display information generation management unit 6
The latest altitude information 9 of the aircraft recorded in the information recording unit 5 is retrieved and taken in at the timing when the radar information is updated. The altitude information 9 is compared with the altitude instruction information 12 of the controller, and when the altitude information 9 matches, the altitude change instruction completion display information 1 is displayed.
3 is generated and output to the display device 2 as display information 11.

The display device 2 which has received the display information 11 indicating the completion of the altitude change instruction updates the display of the altitude of the corresponding flight strip, highlights it for a certain period of time, and alerts the controller.

FIG. 2 is a flowchart showing the operation of the air traffic control system.

Next, the operation of the present embodiment will be described in more detail with reference to FIGS.

When requesting a change in the altitude of the aircraft (step 1: S1), the controller inputs the altitude instructed wirelessly to the aircraft from the input unit 7 of the display device 2 as flight strip information of the target aircraft (step S1). Step 2: S
2). The designated altitude information 14 is processed via the communication processing unit 3 of the information processing apparatus 1, transmitted to the display information generation management unit 6 as the designated altitude information 12, and held (step 3:
S3). The display information generation management unit 6 creates the display information 13 indicating that the altitude change is being instructed, and transmits the display information 13 to the display device 2 (Step 8: S8). Here, the display information 11 indicating that the altitude change of the target aircraft is being instructed is sent to the display device 2, and the display device 2 is updated (step 9: S9).

On the other hand, the secondary monitoring radar 2 for SSR and SIF
The altitude information 23 from 0 is received (Step 5: S5),
The altitude information 9 processed via the communication processing unit 3 of the information processing device 1 is recorded in the information recording unit 5 (Step 6: S
6).

The display information generation / management unit 6 makes a comparison determination as to whether the designated altitude information 12 input by the controller and the altitude information 9 recorded in the information recording unit 5 match (step 4: S4). If the result of the comparison in step 4 is that they match, display information 13 indicating the completion of the altitude change instruction is created (step 7: S7), and the display content is updated to display contents indicating the completion of the altitude change of the target aircraft by the display information updating process. The display information 11 processed via the communication processing unit 3 is transmitted to the display device 2 to update the display information (step 9: S9).

At step 9, the display information 11 indicating the completion of altitude change
Is changed to the display indicating the completion of the altitude change, and is highlighted for a certain period of time, to call the attention of the controller (Step 10: S10).

By visually checking the highlighted display information, the controller can determine that the target aircraft has reached the designated altitude (step 11: S11).
The display information 11 for which the altitude change has been confirmed is displayed on the other display device 2a,
2b.

If it is determined in step 4 that the comparison results do not match, the flow returns to step 3 to repeat the above operation.

As described above, the controller operates the display devices 2, 2a,
When the command altitude information 14 of the flight altitude wirelessly instructed to the aircraft is input from the input units 7, 7a, 7b of the 2b, the information processing device 1 holds the content as the command altitude information 12, and displays the information on the display devices 2, 2a. , 2b is updated to "altitude change instructing". Next, the instruction altitude information 12 held by the information processing apparatus 1 is compared with the altitude information 9 of the aircraft received from the secondary radar 20, and it is determined that the instruction to the aircraft has been completed at the time of coincidence, The display information 11 is transmitted to the corresponding flight strip of the display device 2, 2a, 2b, and the display is updated to a display indicating completion of the altitude change instruction.

The display devices 2, 2a and 2b emphasize the display of the completion of the altitude change instruction and display it for a certain period of time to call attention of the controller. Therefore, the controller need only visually check the flight strips of the radar display devices 2, 2a, 2b indicating the flight status of the aircraft, and the load on the controller can be reduced.

[0033]

As described above, the air traffic control system of the present invention can eliminate the operation step for the controller to input the information that the change of the flight plan has been completed, so that the efficiency of the control operation can be improved. In addition, since the air traffic controller can always watch the operation status of the aircraft, the air traffic control has the effect of improving the safety.
