Abstract

PROBLEM TO BE SOLVED: To provide a CPDLC message answering method capable of quickly transmitting a response message in the case of receiving a plurality of messages. SOLUTION: In this CPDLC message answering method in a CPDLC system for performing communication between a traffic controller and an airplane pilot by message exchange by data link, the messages simultaneously received from the same airplane are displayed on a display device 1 in the order of priorities of the messages, and a reply message is prepared in the order of the priority and transmitted to the airplane.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a controller-pilot datalin (CPDLC) in which communication between a controller and a pilot is performed by a message exchange via a data link at an air traffic control console.
k Communications) A CPDLC message reply method for returning a CPDLC message used in a system.

[0002]

2. Description of the Related Art CPDLC (Controller-Pilot Datalin)
k Communications) system is currently under development for the purpose of trial operation and evaluation. Regarding the response method when responding to this CPDLC message, when multiple CPDLC messages are received simultaneously from the same aircraft, The response message to the received message is to be sent together as a whole in the same manner as the reception.

[0003]

However, in the conventional CPDLC message reply method, even if a plurality of received messages include a highly urgent message, a reply message is created and transmitted for all the messages. And a lack of flexibility due to the inability to respond quickly.

[0004]

SUMMARY OF THE INVENTION A CPDLC according to the present invention
The message reply method includes an input means for inputting an operation instruction of the controller, a display means for displaying at least a screen for creating a message, and a screen display of the display means based on the operation instruction from the input means. And communication means for performing communication between a controller and an aircraft pilot by message exchange via a data link.
In the CPDLC message reply method in the PDLC system, messages simultaneously received from the same aircraft are displayed on the display unit in the order of the priority of the message, and a reply message is created in the order of the priority and transmitted to the aircraft. Things.

[0005]

FIG. 1 is a hardware configuration diagram to which a CPDLC message reply method according to an embodiment of the present invention is applied. In FIG. 1, 1 is a CRT type, for example.
LCD (liquid crystal) type or PVD (Plane View Displa)
y, radar display device, etc., 2 is, for example, a PC
The control device 2 includes functional units such as a pointing device processing unit 11, a display processing unit 12, and a message creation control unit 13. Reference numeral 3 denotes a pointing device such as a mouse.

Next, the operation of replying to a CPDLC message according to this embodiment will be described. First, the display on the display device 1 will be described. 2 shows an example of a display area on the display device 1, FIG. 3 shows a specific example of a screen display of an aircraft selection area, and FIG. 4 shows a specific example of a screen display of a CPDLC message history display and an aircraft information display area. Figure showing
FIG. 5 is a diagram showing a specific example of a CPDLC message input and screen display of a transmission area.

As shown in FIG. 2, a display area on the display device 1 usually includes, for example, an aircraft selection area as an area 1,
Aircraft status display area as area 2, CPD as area 3
An LC message history display and aircraft information display area, and a CPDLC message input and transmission area as an area 4 are displayed. For example, an aircraft symbol or the like as shown in FIG. By selecting an aircraft, the area 2 associated with that aircraft
To 3 are displayed.

[0008] In the area 3, a CPDL from an aircraft is provided.
The C messages are displayed in the order of higher priority. When the CPDLC message is displayed in this area 3, the screen for creating a CPDLC message in response to the CPDLC message in the order of higher priority is displayed in the area 4. , A CPDLC reply message is created in the area 4 and can be transmitted for each CPDLC reply message.

First, in the display device 1, the display processing unit 12 displays, in a region 1 (aircraft selection region) shown in FIG. 2 as a symbol, for example, a traveling aircraft as shown in FIG. When the CPDLC message is received from the aircraft A, the aircraft symbol blinks. Then, the controller operates the pointing device 3, moves the cursor on the display screen displayed on the display device 1 as shown in FIG. 3, for example, over the aircraft symbol A, and operates the pointing device 3 to operate the aircraft. A
Select At this time, the pointing device processing unit 11 sends the position and click information to the message creation control unit 1 based on the information received from the pointing device 3.
3

The message processing control unit 13 controls the display processing unit 12 based on the information obtained from the pointing device processing unit 11, and the CPDLC message received from the aircraft A is displayed on the display device 1 continuously in the area 3. Will be displayed. In the display of the CPDLC message, messages received at the same time are displayed in descending order of priority.

When the CPDLC message is displayed on the display device 1, the cursor automatically moves to an area 4 (CPDLC message creation area) shown in FIG.
For example, a screen as shown in FIG. 5 is displayed, and a message can be created. Then, each time the controller operates the pointing device 3 and clicks the “Transmit” button shown in FIG. 5 each time a message is created, the message is transmitted, and the message created when the “Reserve” button shown in FIG. 5 is clicked. Is stacked in the buffer. Also, a maximum of five message stacks by “Reserve” are possible, and they are transmitted together when “Transmit” is performed next.

In this embodiment, since the CPDLC messages received from the aircraft A are displayed in the order of priority for the messages received at the same time, a reply message is immediately created for a message with a high priority. The message reply method can be made flexible, for example, it is possible to respond quickly in an emergency or the like. In addition, by displaying the priority of each message in consideration, the priority of the received message can be determined at a glance.

In this embodiment, a display screen as shown in FIGS. 2 to 5 has been described as an example. Such a display form may be adopted. Further, in this embodiment, the operation is performed using the pointing device 3, but other input means may be used as long as the operation of creating the CPDLC message can be performed.

In this embodiment, an example in which the present invention is applied to a method of replying a CPDLC message has been described.
It may be used for replying to a message in DC (ATS Interfacility Data Communications).

[0015]

As described above, according to the present invention, a message received from an aircraft is displayed on the display means in the descending order of the priority of the message, and a reply message is created in the descending order of the priority. To be able to quickly create and send a reply message to a high-priority message, giving flexibility in how to reply to the message, such as being able to respond quickly in an emergency. It has the effect that can be done.
