Description

  The present invention relates to monitoring a call sign used for a call when communicating between a controller and a pilot, and more particularly to a digital voice signal for notification in a time division multiplexing VHF digital link mode 3 (VDL MODE3) radio line. The present invention relates to an aerial radio communication call sign monitoring system and method for adding a local user ID for identifying an aircraft to the vehicle and monitoring and displaying a call sign corresponding to the local user ID with reference to control information.

  The conventional aeronautical radio communication system is analog radio communication and transmits and receives only voice. When calling a controller or pilot to communicate with, a call sign is used for the pilot, an abbreviation for the control facility is used for the controller, and the other party responds with the call sign or abbreviation. Recognize Therefore, the pilot or controller speaks a call sign or abbreviation for each communication.

  There is a movement to replace the aircraft-to-ground system communication from analog wireless communication to VHF digital link mode 3 (VDL MODE3) which is digital wireless communication. VDL MODE3 is a time-division multiplex digital wireless communication system defined by the International Civil Aviation Organization, which transmits and receives data and digital audio simultaneously by dividing one frequency into 3 or 4 time slots. Can do. In recent years, the introduction of this time division multiplexing digital wireless communication system has been progressing.

  There is a communication system for control corresponding to both communication means of voice communication and data link communication. In this system, a communication switching unit is provided to recognize whether the communication is voice communication or data communication from the received signals of the voice communication transmitting / receiving unit and the data link communication transmitting / receiving unit, and use them by switching. In this example, since data and voice cannot be used simultaneously, it cannot be used for communication with an identification code attached to the voice (for example, Patent Document 1).

  In addition, there is a system that transmits positioning data to the controlled object monitoring system by the VHF time division multiplex communication method. In order to transmit the positioning data from the aircraft to the control facility, the positioning data is transmitted to the time slot assigned to itself, and the vacant time slot is used for relaying the positioning data of other aircraft. This scheme eliminates the need to send and receive aircraft identification codes by assigning specific aircraft to time slots. This example can be used for automatic data communication such as positioning data. However, in the case of control communication in which controllers and pilots communicate with each other while recognizing each other, the call sign cannot be omitted in procedures that require recognition of the other party by calling or responding (for example, patents) Reference 2).

JP 2000-182200 A (column number 0024-0026) JP-A-8-171212 (column numbers 0045-0048)

  In control communication using a radio link for a mobile unit including a conventional aircraft, data is not transmitted unilaterally, but communication is performed through conversation while recognizing each other. Therefore, he speaks his abbreviation and the call sign of the other party at every communication. Therefore, the following problems arise.

  The first problem is that there is no means for confirming whether the pilot or the controller correctly speaks the call sign of the opponent and whether the correct opponent is responding. It is difficult to check the utterance if the controller or pilot makes a mistake in calling the call sign, or if the call sign is missed.

  The second problem is that controllers and pilots can mistake call signs. The reason is that the pilot or controller is not aware of the intended call sign of the other party, but is mistakenly unaware that he is speaking the wrong call sign. This careless mistake cannot eliminate the possibility of mistakes, no matter how carefully people do what they do. In particular, the controller uses different call signs for a plurality of aircraft depending on the other aircraft, and the call signs themselves are similar codes.

  The third problem is that there is a possibility that the call sign may be mistaken. This is because it may be difficult to hear if the airborne propagation state in wireless communication is bad. Further, in the case of call sign transmission by voice, the voice may be interrupted in the middle depending on the operation timing of the microphone switch of the speaker.

  A call sign monitoring system and method for aeronautical radio communications that solve the above problems are provided. When VHF digital link mode 3 (VDL MODE 3) is adopted for control communication, data and digital voice can be simultaneously transmitted and received in one time slot. The ground equipment at the control facility receives the voice from the on-board equipment of the aircraft as a digital voice signal, and the sender's identification number attached to the digital voice signal is collated with the call sign of the aircraft by the data matching device. A call sign corresponding to the identification number is displayed on the information display device. That is, the voice call sign is not identified by the ear, but is associated with the call sign by the identification code attached to the digital voice signal, and the call sign is presented to the controller on the display device. The controller can view and monitor whether the call sign of the aircraft he called for has been correctly answered.

  Aircraft pilots contact various controllers during operation, solicit control instructions and report. Therefore, the pilot communicates by changing the radio frequency, changing the time slot assignment, changing the identification number, or the like depending on the facility of the other party to be controlled. Thus, there is a local user ID to identify the aircraft in operation. This is a term in the VDL MODE3 standard, and is an international agreement with an identification number temporarily assigned to an aircraft under control.

  There is also an aircraft address that uniquely identifies the aircraft. This is a 24-bit identification code called an ICAO address, which is fixedly assigned to each aircraft and is internationally negotiated.

  An aircraft in service is usually called by flight number. This is called a call sign and is described in the flight plan. Controllers and pilots are used when calling other aircraft and identifying themselves.

  The control information is information in which an aircraft address, which is an aircraft identification, is additionally described in the flight plan information when the aircraft is operating. The control information is used in the call sign monitoring system and method of the present invention and is held by the aircraft control information management device.

  The voice of the pilot call is converted into a digital voice signal, and the signal is transmitted with a local user ID. The communication device at the control facility detects the aircraft address from the link establishment request received from the aircraft. The communication device in the control facility returns a communication link establishment response for assigning a new local user ID. Further, the aircraft address is sent to the aircraft control information device, and the control information is referred to and the aircraft address, call sign, and local user address ID are associated with each other and held.

  On the other hand, the aircraft retains the local user ID assigned by the communication link establishment response, attaches the local user ID to the call to the control facility or the digital voice signal of the response, and transmits it to the control facility. The control facility detects the local user ID in the digital audio signal, obtains the corresponding call sign from the control information, and monitors and displays it on the call sign display device. By executing this process, not only the call sign of the responding aircraft can be confirmed by voice, but also the call sign can be extracted from the local user ID attached to the response and visually confirmed on the display device. Therefore, in the unlikely event that the controller calls on an unintended aircraft or receives a report, the call sign can be confirmed visually.

  An object of the present invention is to allow a controller to visually recognize a call sign of a communication partner by displaying the call sign of the aircraft in comparison with the control information in communication with the aircraft to which the controller assigns a local user ID. By preventing careless mistakes.

  Therefore, when the communication device establishes a communication link with the VHF digital link mode 3 (VDL MODE3) radio line between the ground device of the air traffic control facility and the onboard device mounted on the aircraft of the present invention, a pilot report is made. When the communication link of the radio link is not established, an aircraft address is added to the link establishment request, and when the link of the radio link is established, the notification digital voice signal is With the user ID attached, the aircraft address used for reporting from the pilot to the controller, the aircraft address of the aircraft used for the control communication exchanged between the controller and the pilot, and the flight plan information thereof are obtained.

  Further, the ground device is a communication including a ground voice input / output device for inputting / outputting voice to / from the controller and a local user ID newly assigned to a link establishment request including the aircraft address received from the onboard device. When the link establishment response is returned and the digital voice signal including the local user ID is received, the local user ID is associated with the corresponding call sign, and the timing of the radio line of the onboard communication device is synchronized. A ground communication device that transmits a reference signal at a predetermined period; a notification of the aircraft address from the ground communication device; the aircraft address and a local user ID assigned to the aircraft address are associated with each other; Detect call sign corresponding to aircraft address and associate aircraft address with call sign A data verification device that receives the notification of the local user ID from the ground communication device and associates the call sign, and information for monitoring and displaying the call sign corresponding to the local user ID notified from the data verification device for each notification And a display device.
