JP4506610B2 - Operation control communication system and frequency conversion instruction method in operation control communication - Google Patents

Description

  The present invention relates to an operation control system and a frequency conversion instruction method in operation control communication, and in particular, an operation control communication system that performs communication between a communication device of an operation subject to be controlled and a communication device on the control side, and The present invention relates to a frequency conversion instruction method in the communication.

  Conventional air traffic control wireless communication is analog communication, and when a controller issues a frequency change instruction to a pilot, the controller uses a microphone to give an instruction verbally. Upon receiving this instruction, the pilot verbally informs the controller about the frequency change instruction. Further, according to this instruction, the frequency changing device is operated so as to match the frequency as instructed.

  However, in such a system, only analog voice communication is used, so in order to issue a frequency conversion instruction to the aircraft, it is necessary to convey the frequency verbally each time, and the workload increases as the number of controlled aircraft increases. It has risen. In addition, there was a possibility that the controller would make a mistake or that the pilot could miss it.

  Therefore, a technique for improving efficiency in the control instruction is disclosed. For example, in Patent Document 1, the transmission operation time is shortened by reducing the number of operations such as selection / confirmation of control instruction contents and operation cancellation in the middle of the operation, and interactive communication equivalent to voice communication is realized. A control communication issuing system that can reduce a thinking load in a transmission operation by simplifying a selection operation by a typical operation is disclosed.

  Patent Document 2 discloses a CPDLC message creation method for creating a CPDLC message used in a CPDLC (Controller-Pilot Datalink Communications) system that performs communication between a controller and a pilot by exchanging data link messages in an air traffic control console. Is disclosed. In this CPDLC message creation method, a CPDLC message is created by repeatedly performing an operation instruction from the input unit based on the screen display displayed on the display unit, and the CPDLC message is hierarchized. Since a CPDLC message is created by giving an operation instruction from the input means for each layer, there is an effect that a mistake in wording does not occur when creating a message. Further, since the messages are hierarchized, it is possible to select from a small number of candidates at each selection stage without selecting one message from the whole message, and the creation time can be shortened.

  By the way, in the prior art disclosed in Patent Document 1 and Patent Document 2, the workload of the controller is reduced. However, since the configuration is only a ground system, the workload on the aircraft side is not reduced, and the air traffic control Business efficiency in the communication system is insufficient. For example, since there is no description that TDMA communication is used in the prior art, it is considered that data communication and voice communication are performed using different frequencies and different protocols. In this case, unless there is a special idea, the change of the voice channel by the control instruction using data cannot be automated. For this reason, it is considered that the pilot only transmits the frequency with the message, and the pilot who confirmed the display (frequency) of the message changes the frequency by manual operation. There is a possibility to change. Further, since there is no way for the controller to know whether the frequency change result is correct or incorrect, it may take time to notice the error if the frequency change is incorrect.

  Furthermore, the technique disclosed in Patent Document 2 lacks versatility because it is limited to a system that implements a CPDLC application and has a frequency change instruction message set.

  FIG. 1 is a block diagram showing the configuration of the air traffic control communication system according to the first embodiment of the present invention. In FIG. 1, the air traffic control communication system includes an onboard device 1, a ground device 2, and a ground rear device 3. The onboard device 1 includes an onboard information display input device 11 and an onboard communication device 12. The onboard information display input device 11 displays next frequency instruction information and accepts a change confirmation input to the displayed next frequency. The on-board communication device 12 manages communication with the ground communication devices 21a and 21b. The on-board communication device 12 has an interface with the on-board information display input device 11 and automatically changes to the frequency as instructed when the pilot confirms the frequency change instruction data issued by the ground device 2. can do.

  On the other hand, the ground device 2 includes ground communication devices 21 a and 21 b, a control information display input device 22, and a pointing device 23. The ground communication devices 21 a and 21 b have an interface with the control information display input device 22 and execute communication with the on-board communication device 12. It is assumed that the ground communication device 21a and the onboard communication device 12, and the ground communication device 21b and the onboard communication device 12 are operated at different frequencies. The control information display input device 22 displays the position information of the aircraft and accepts an input of a next frequency instruction for the aircraft by operating the pointing device 23. The pointing device 23 is a device such as a mouse, a trackball, or a digitizer, and performs input such as a pointer operation and menu selection to the control information display input device 22.

  The ground rear device 3 includes an air traffic control information supply device 31, manages aircraft position information, and provides the aircraft position information to the control information display input device 22.

  Next, the operation of the air traffic control communication system will be described with reference to FIG. First, the ground communication device 21a periodically transmits radio waves in order to inform the arbitrary on-board device 1 of the presence of the own device and the timing of the time division multiplexing method. When the on-board communication device 12 receives the radio wave from the ground communication device 21a and completes time synchronization with the ground communication device 21a, the onboard communication device 12 establishes a communication link with the ground communication device 21a. A link establishment request including is transmitted. When receiving the link establishment request, the ground communication device 21a transmits a link establishment response including the onboard device identification number to the onboard communication device 12. Further, the ground communication device 21 a transmits the aircraft address to the control information display input device 22. The control information display input device 22 displays that the aircraft is in a link established state based on the aircraft address received from the ground communication device 21a. The above is the operation related to establishment of the communication link.

  Next, the controller inputs a frequency change instruction for a specific aircraft based on the aircraft position display of the control information display input device 22. This frequency change instruction input is performed by a method in which the pointing device 23 moves the pointer to the display of the aircraft and displays (for example, clicks) to display frequency options, and the controller selects the frequency. Alternatively, the frequency is selected by dragging and dropping the display of the aircraft. The input frequency change instruction data is output to the ground communication device 21a. The ground communication device 21 a transmits frequency change instruction data to the onboard communication device 12.

  The onboard communication device 12 outputs the received frequency change instruction data to the onboard information display input device 11. The on-board information display input device 11 displays the received frequency change instruction and waits for pilot confirmation. When the pilot performs confirmation input by operating a button or the like, the onboard information display input device 11 outputs confirmation input data to the onboard communication device 12. Then, the on-board communication device 12 automatically changes the frequency in accordance with the frequency change instruction.

  The on-board communication device 12 establishes a link with the ground communication device 21b that is configured in the same manner as the ground communication device 21a and operates at a different frequency. The ground communication device 21b notifies the control information display input device 22 that the onboard device 1 is linked to the ground communication device 21b.
