Description

A method and system for electronic handover between high and low fan control units

technical field

The invention relates to the technical field of traffic control in civil aviation, in particular to a method and a system for realizing control screen handover by different air traffic control automation systems between different high and low fan control units.

Background technique

The rapid development of my country's civil aviation industry has put forward higher requirements for civil air transport infrastructure to meet the rapidly growing demand for air transport business. As an important infrastructure in the civil aviation transportation system, the civil air traffic control automation system plays a very important role in promoting air traffic safety, maintaining air traffic order, ensuring smooth air traffic, and improving flight efficiency. Air traffic control is the center of the safety and efficiency of the civil air transport industry. The level of air traffic control plays a vital role in accelerating flight flow, improving airspace utilization, and promoting the sustainable and coordinated development of the air transport industry.

There are currently two ways to hand over a flight between different air traffic control units:

First, voice handover, by making a phone call, inform the next flight control service area that a flight is about to enter, the flight's call sign, secondary answering machine, altitude, speed and other information;

Second, AIDC handover, said AIDC is a standard protocol for data communication and control electronic handover developed by the International Civil Aviation Organization for adjacent flight control service intervals in the Asia-Pacific region. This standard protocol uses messages to realize data transmission. The current control service area sends the flight's call sign, secondary transponder, altitude, speed and other information to the next control service area through messages.

The above two handover methods have their own characteristics:

As a traditional handover method, voice handover has the advantages of convenience, speed, and effectiveness when the flight volume is small. When it is large, the control personnel cannot concentrate on adjusting the flight interval of the aircraft, which affects the safety of aircraft operation.

As a new electronic handover method, AIDC handover uses the automatic information processing function of the air traffic control automation system to exchange flight information, reduces the use of voice handover, and reduces the coordination workload of controllers. Controllers can concentrate more on screen monitoring and deployment of aircraft conflicts , Play a positive role in ensuring flight safety and smooth flight. However, AIDC handover also has limitations. AIDC handover messages have many definitions. When the distance between two adjacent control service units is very close, the handover needs to be completed before the AIDC message is sent. The time required for the entire AIDC cycle is not sufficient. Handover time requirements; AIDC handover process must have clear route handover point information, which does not meet the current situation that different control units of the high and low fans need electronic handover.

Contents of the invention

In order to solve the technical problem that the time required for the entire cycle of the existing AIDC cannot meet the handover time requirements between adjacent control service units, and AIDC handover must have route handover point information, which cannot meet the electronic handover required by different control units in the high and low sectors and the control personnel of the existing voice handover can not concentrate on adjusting the flight interval of the aircraft when the flight volume is large, which affects the technical problem of the safety of the aircraft operation. The invention provides a method for electronic handover between high and low fan control units and its system.

The first aspect of the present invention provides a method for electronic handover between high and low fan control units, the method comprising:

Step S1: When the first control area has a correlation with the flight radar track, and the first control unit has the control authority, when the sending conditions set by the system are met, the flight plan data coordination message will be automatically sent;

Step S2: The second control unit receives the flight plan data coordination message from the first control unit, and the flight is about to enter the control area of the second control unit;

Step S3: The first control unit actively sends a handover request message to the second control unit, and after the second control unit receives the handover request message, the flight enters the handover state;

Step S4: If the second control unit sends a handover reception message, the handover is completed, the second control unit obtains the control authority, and the first control unit releases the control authority.

The second aspect of the present invention provides an electronic handover system between high and low fan control units, the electronic handover system between high and low fan control units is respectively deployed in the first control unit and the second control unit, and the high and low fan The electronic handover system between control units includes the electronic handover system of the first control unit and the electronic handover system of the second control unit through their respective control handover interface servers. The electronic handover system of the first control unit sequentially sends the flight plan data coordination message and the handover request message; the electronic handover system of the second control unit sends the handover reception message to complete the handover.

Beneficial effects of the present invention: the electronic handover method and system between the high and low fan control units provided by the present invention can automatically generate the technical characteristics of the handover message, which can meet the handover time requirements between adjacent control service units at close distances, and solve the problem The time required for the entire cycle of the existing AIDC cannot meet the requirements of the handover time between adjacent control service units at close distances, and AIDC handover must have route handover point information, resulting in technical problems that cannot meet the electronic handover required by different control units in the high and low sectors; and The control personnel of the existing voice handover cannot concentrate on adjusting the flight interval of the aircraft when the flight volume is large, which affects the technical problems of aircraft operation safety. The present invention does not require AIDC handover and must have route handover point information, which can well satisfy the electronic handover of different control units in the high and low sectors; and enables the control personnel to concentrate on adjusting the flight interval of aircraft when the flight volume is large, thereby ensuring the safety of aircraft operations.

2. Cancel handover (HRC), which means that after the "request handover" operation has been initiated on the flight with the control authority of the control unit, the control unit needs to cancel the "request handover" status.

3. Receive handover (HRP), which means that after the "request handover" operation has been initiated on the flight with the control authority of the control unit, the next control unit will accept the handover of the flight.

4. Refusal to handover (HRF), which means that after the "request handover" operation has been initiated on the flight with the control authority of the control unit, the next control unit will not accept the handover of the flight.

2. Definition of handover message

According to the operating status and steps of flight electronic handover between control units, six handover messages are defined, including: flight plan data coordination message IFPL, handover request message IHRQ, handover cancellation message IHRC, handover reception message Text IHRP, handover rejection message IHRF, logic confirmation message ILAM, wherein:

1. Flight plan data coordination message (IFPL), the synchronization message of flight plan data between the next control unit before the flight handover;

2. Handover request message (IHRQ), a message that needs to be sent to the next control unit after the current control unit initiates a handover request operation command;

3. Handover cancellation message (IHRC), when the current control unit initiates a handover request operation command and the next control unit does not receive it, it is necessary to cancel the message sent by the handover request operation command;

4. Handover receiving message (IHRP), the current control unit initiates a handover request operation instruction, and the next control unit accepts the message sent after the handover request;

5. Handover rejection message (IHRF), the current control unit initiates a handover request operation command, and the next control unit does not accept the message sent by the handover request;

6. Logical confirmation message (ILAM), after sending each type of message above, if received, it will be confirmed by the message;

3. Content of handover message

6. Logical confirmation message ILAM

The logical confirmation message ILAM includes the following contents: receiving message address, sending message address, message type, basic information of the confirmation message (flight number, departure airport, landing airport, execution date, estimated departure time, and flight number used by the flight) secondary code).

4. Definition of flight plan status and handover process during the handover process

The state definition of the flight plan during the handover process is related to the current sending and receiving messages. The system defines the following flight plan states according to the message situation:

1. Activate. The activated state indicates that the current control area has a correlation with the radar track, and the current control area has control authority, and the flight plan data coordination message IFPL can be automatically sent to the next control unit when the server message sending condition is met. The sending conditions of the server message include: the controller sets the XFL; the target enters a certain altitude.

2. Coordination. Coordination status indicates that the flight has received the flight plan data coordination message IFPL from the upper control unit, and the flight is about to enter the control unit.

3. Handing over. In handover, it means that the control unit of the current flight actively sends a handover request message IHRQ to the next control unit, and the handover receiver receives and replies to the logical confirmation message ILAM, and the flight status enters handover.

4. The handover is completed. Handover completion means that the flight is in the process of handover. If the handover initiator sends the handover receiving message IHRP, the handover is complete, the handover receiver obtains the control authority, and the handover requester releases the control authority.

5. System structure

The high-fan air traffic control (ATC, AirTrafficControl) system and the low-fan air traffic control ATC system belong to the ATC systems of different manufacturers, and the data is transmitted between the two systems through the "control handover interface server". When the altitude is low, the high-fan ATC system sends in sequence: the flight plan data coordination message IFPL, and the handover request message IHRQ. The low fan sends the handover and receives the message IHRP to complete the handover.

The above is only a specific implementation mode in the present invention, but the scope of protection of the present invention is not limited thereto. Anyone familiar with the technology can understand the conceivable transformation or replacement within the technical scope disclosed in the present invention. All should be covered within the scope of the present invention.
