Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a system for automatically generating traffic control messages for traffic control.

[0002]

2. Description of the Related Art An example of air traffic control, which is a typical example of traffic control, will be described. For example, air traffic control operations in Japan are performed by four ACCs (Air Traffic Control Department) in Sapporo, Tokyo, Fukuoka and Naha. The airspace assigned to each ACC is divided into a plurality of areas called sectors. A control console is provided for each sector, and a controller is assigned to each control console. A display device of an RDP system (airway radar information processing system) is placed on the control console. The RDP system captures an aircraft flying on an air route with radar, links the flight plan information received from the FDP system (flight plan information processing system) to a display device, and displays the link on a display device. The aircraft information displayed on the display device is the aircraft position, speed, altitude, aircraft identification, and the like. While monitoring the position of the aircraft displayed on the RDP system, the air traffic controller issues various air traffic control messages (permissions, instructions, etc.) to the pilots of each aircraft by radio telephone to perform collision avoidance and flight assistance. Control to fly safely.

[0003]

The tasks of the controller include voice communication with the pilot, monitoring of the radar display screen, operation of the system, and the like. You will be busy with your voice communication work.

[0004] Naturally, there is a limit on the radio frequency used for control communication, so if the number of aircraft to be controlled increases, communication becomes congested, and the above problem is spurred.

[0005] Further, in the control communication by voice between the controller and the pilot, due to the nature of the voice conversation, mistaken listening,
Misstatements and misunderstandings may occur. Especially when communication becomes congested, the controller must be quick to speak, the number of things to think about increases, and the possibility of mistakes increases, and the pilot side can also miss or miss The nature becomes high.

Further, since voice is transient, it is necessary to communicate again to confirm it again. This also causes communication to be congested and promotes the above problem.

A similar problem is not limited to air traffic control,
It may be present in other traffic control operations.

Accordingly, an object of the present invention is to provide a control message generation system capable of automatically generating a control message for traffic control and giving the control message to a control target in order to reduce the above-mentioned problems. is there.

Another object of the present invention is to provide a control message generation system that can automatically provide an appropriate control message to an appropriate target at an appropriate time according to traffic conditions.

Still another object of the present invention is to provide a control message generating system capable of providing a control message in such a form that the side receiving the control message can accurately recognize the control message and can easily confirm it again. Is to do.

[0011]

A control message generating system according to the present invention comprises: detecting means for detecting a predetermined opportunity to issue a control message based on predetermined information;
An element table in which various kinds of predetermined data that can be constituent elements of the control message are registered, and one or more pieces of data are selectively obtained from the element table in response to the detection of the trigger by the detection unit, and the obtained data And a transmission means for transmitting the control message in the data format to the control target.

According to this control message generation system, a predetermined trigger for issuing the control message is automatically detected, and the control message is automatically generated and transmitted to the control target, so that the burden on the controller is reduced. In addition, since the control message is generated and transmitted in a data format such as text data instead of a voice signal format, the transmission is short, and the communication congestion can be reduced. Further, the control message in the data format is convenient for storing and printing out or displaying the message on the control target side receiving the message. This contributes to the accurate and reliable notification of the control message and easy reconfirmation. From this viewpoint, it is desirable that the control target side has a means such as a printer capable of outputting the received control message in the data format, particularly in the form of a hard copy of a character string.

Preferably, the detecting means detects predetermined plural types of triggers corresponding to different types of control messages, and the generating means generates a control message corresponding to the detected trigger type. Thereby, an appropriate control message according to the situation can be automatically generated.

[0014] Preferably, the identification of the control target of the transmission destination can be added to the generated control message. Thus, when the control message is broadcasted by radio or the like, the control target can select and receive only the message addressed to itself, thereby contributing to accurate and reliable transmission of the message.

It is a message. The system further includes a navigation data file in which data indicating a navigation state of various control targets is recorded. The detecting means detects completion of a predetermined communication for control transfer between the transfer-side control organization and the inheritance-side control organization as a trigger for issuing an instrument standard value change message. In the element table, the data of the message code of the instrument standard value change message and the data of the instrument standard value used in various control areas are registered. In response to the detection of the completion of the predetermined communication, the generation unit determines whether or not the control target is in a predetermined navigation state by referring to the navigation data file of the control target, and the determination result is positive.

FIG. 1 shows a schematic configuration of an example of an air traffic control system to which the present invention can be applied.

ACC (Air Traffic Control Department) 1A, 1
In B, RDP systems (aircraft radar information processing systems) 3A and 3B and CIO systems (control input / output systems) 5A and 5B are installed. Each RDP system 3
A and 3B are communicably connected to a radar site 7, an FDP system (flight plan information processing system) 13, and another adjacent RDP system. These systems are involved in air traffic control in cooperation with various other external systems. However, from the viewpoint of air traffic security, other systems will not be described in this specification, and the present invention will be applied to the above-described systems. I will not explain anything other than what I think is the minimum necessary for understanding. However, the description herein
Those skilled in the art can sufficiently and clearly understand the present invention.

The CIO systems 5A and 5B are related systems of the RDP systems 3A and 3B, and include sector integration,
Change of QNH (altitude standard value) to RDP system 3A,
Used for inputting to 3B.

Each of the RDP systems 3A and 3B includes a display device with a touch panel (PVD) 21 on a control desk for each sector.
A to 21C and 21D to 21F. Each PVD2
1: 1 DCU for 1A-21C, 21D-21F
(Display control device) 23A to 23C and 23D to 23F are connected. DCUs (display control devices) 23A to 23
C, 23D to 23F are the respective RDP systems 3
A, 3B are connected to the CPUs 25A, 25B.

Each RDP system 3A, 3B transmits SSR data (aircraft 9,
11), and flight plan information (flight plan) of each of the aircrafts 9 and 11 from the FDP system (flight plan information processing system) 13. CPU25
A and 25B link the SSR data of the aircrafts 9 and 11 with the flight plan information of the aircrafts 9 and 11, and
21C, 21D to 21F are displayed. In addition, each PVD2
The information input by the controller from the touch panels 1A to 21C and 21D to 21F is the DCUs 23A to 23
C, 23D to 23F are sent to the CPUs 25A, 25B.

Each of the RDP systems 3A and 3B further has a function of automatically generating and transmitting a control message to each of the aircrafts 9 and 11 according to the principle of the present invention. Hereinafter, this function will be described in detail.

FIG. 2 schematically shows a procedure for transmitting an automatically generated control message to an aircraft pilot.

When the control message is automatically generated (step S1), the RDP system 3 converts the control message into, for example, PVD2.
1 to the controller (S2). When an input from the controller indicating that the message has been approved is made, for example, on the touch panel of the PVD 21, the message is wirelessly broadcast to the aircraft in flight in the sector in charge (S
3). The control message automatically generated is not a voice signal but data in a form suitable for machine recognition, such as a text code, as will be specifically described later. Therefore, the transmission of the control message in the data format is completed in an extremely short time as compared with the control message in the form of a voice signal issued by a controller via a wireless telephone. This is one important factor in reducing communication congestion.
After broadcasting the message, the RDP system 3 waits for a response from the aircraft (S4).

In the broadcast control message in the data format, the identification of the aircraft of the transmission destination is set, for example, in its header. Each aircraft selects and receives only a message having its own identification from the broadcasted control messages (S11). When each aircraft successfully receives the control message, it returns an acknowledgment to the RDP system 3 and saves the received control message in a storage device, and then outputs this in the form of, for example, a hard copy character string from a printer. And present it to the pilot (S12, S13). In parallel with (or in place of) the printer output, voice output from the voice synthesizer may be performed, or a soft copy character string may be displayed on a display. However, printing out a hard copy of the control message is a good way to correctly and reliably communicate the control message to the pilot and to allow the pilot to reconfirm if necessary. It is also important from the same viewpoint that the control message is stored in the on-board storage device.

Upon receiving the confirmation response from the aircraft, the RDP system 3 indicates to the controller via the PVD 21 that the transmission has been completed (S5). The controller enters necessary information accompanying the end of transmission of the control message into the RDP system 3 (S6). The information to be entered in step S6 is, for example, the altitude after the change when the “altitude change instruction message” is issued, and the like, but “frequency change instruction message”, “QNH change instruction message”, and “QNH change instruction message” described later in detail. When the "radar traffic information message" is issued, there is no particular information to be entered.

FIG. 3 shows a configuration of a part for automatically generating a control message in the RDP system 3.

There are many types of control messages currently used. FIG. 3 shows three types of control messages, namely, "frequency change instruction message", "QNH change instruction message" and "radar traffic information message". 2 is shown for automatically generating a.

Here, the "frequency change instruction message" means that the radio frequency used in the control communication between the aircraft and the control organization (for each sector of the ACC, airport, etc.) is defined for each control area (sector, airport, etc.). Due to differences, when the aircraft moves from one control area to another control area as the aircraft moves from one control area to another control area (this is called "control transfer"), the transfer destination is This message is for the controller of the transfer source area (hereinafter referred to as the transfer side area) to instruct the aircraft about the frequency used in the area (hereinafter referred to as the transfer side area).

The "QNH change instruction message" is the altitude
This message indicates to an aircraft flying less than 14,000 feet (or descending to an altitude less than 14,000 feet) which QNH (altimeter standard value) to be set in the altimeter of the aircraft.

The "radar traffic information message" means that when a target (such as another aircraft) approaching an aircraft under control is recognized, information on the target is notified to the aircraft within a range that can be executed by the controller. It is a message to do.

The above three types of messages are easy to determine by machine processing because the conditions for determining whether or not to issue a message are relatively clear, and the message contents are relatively close to a fixed form. Is easy to determine by machine processing, and the temporal strictness required for the timing of emission is relatively moderate, so that it is suitable for automatic message generation. In addition, since the above three types of messages are actually issued frequently, it is expected that the automatic generation of the messages is highly effective in reducing the burden on the controller. Also, in particular, the radar traffic information message needs to be determined in consideration of the relative positions and speeds of the aircraft in the three-dimensional space, and since there are many items to be included in the message as specifically described later, Although it is a troublesome and difficult task for humans, on the other hand, for machines it is only necessary to perform numerical calculations and incorporate the items according to the results into the message, so the burden on the controller is reduced by automatically generating messages The effect is particularly large, and as long as the emission condition is satisfied, the sound is always emitted reliably, which can contribute to the pilot.

As shown in FIG. 3, the RDP system 3

It has program modules such as an F notification reception processing unit 39 and a message editing unit 41. A transmitting unit 43 for wirelessly broadcasting the control message to the aircraft;
And the PVD 21 and DC for each sector described above.
A hardware module such as U23 is also provided. The storage device of the RDP system 3 stores frequency / main Q
Resources such as an NH table 45, a flight plan file 47 and an SSR data file for each aircraft, and a message item table 51 are stored. further,
As described above, the RDP system 3 is communicably connected to the radar site 7, the RDP system 61 of several adjacent ACCs, and various other external systems 63.

The hand-accept processing unit 31 performs a control transfer process. In general, a controller in the transfer-side area transfers a "HAND-I" command from his / her own PVD 21.
NIT (Hand Initiate) ", and in response, the controller of the inheriting area responds
This is established by inputting a message “ACPT (accept)” from the VD 21. The hand-accept processing unit 31 performs “HAND-INIT” and “ACP
In response to the input of "T", predetermined processing required for control transfer is executed. In the case of control transfer between sectors handled by the same ACC, "HAND-INIT" and "ACPT" are exchanged between the DCUs 23 in the own system 3, and another control agency such as an adjacent ACC or airport. In the control transfer between “HAND-INIT” and “ACPT” between the DCU 23 of the own system 3 and the external system 61 or 63, the hand-accept processing is performed in any case. The unit 31 processes.

The instruction altitude change processing unit 33 is configured to, when the DCU 23 performs a process relating to the change of the altitude indicated for the aircraft locally, and when the process is normally completed,
23 to that effect.

The altitude change processing unit 17 requests the FDP system 13 to perform a process related to the change of the altitude indicated for the aircraft, and when the process is normally completed, the FD
A notification to that effect is received from the P system 13.

The QNH change processing unit 37 is connected to the external system 6
3 receives a change instruction of the QNH of the sector that the system 3 is in charge of, and performs a predetermined QNH change process on the sector (for example, updates the frequency / main QNH table).
Is what you do.

The CNF notification reception processing unit 39 outputs a CNF (conflict alert; approach warning) issued by the DCU 23 when the aircraft under control approaches the target.
3 to perform a process of extracting an approaching aircraft. Note that each DCU 23 has an approach detection function, and when certain conditions are satisfied such as the time until the closest approach, the distance between the two aircraft at the time of the closest approach, and the altitude difference between the two aircraft at the time of the closest approach, the DCU 23 Issue a CNF for the target aircraft.

The message editing unit 53 edits a control message suitable for the scene in response to the processing operations of the various processing units 31 to 39 described above. Message part 5
3. QNH for editing QNH change instruction message
It has a change message section 55 and a radar traffic information message section 57 for editing the radar traffic information message.

FIG. 4 shows the frequency / main QNH table 45.
As shown in FIG. 1, a frequency used in an area in charge of a traffic control organization such as various ACCs and various approaches (airports) and a main QNH value of the area are registered.
When the main QNH value is changed, as described above, the QNH change processing unit 37
Rewrite the NH value.

The flight plan file 47 contains the FDP
The flight plan (flight plan information) for each aircraft provided from the system 13 is recorded. As illustrated in FIG. 5, the flight plan includes an aircraft number, a call sign, a beacon code, an indicated altitude, a departure airport symbol, a destination airport symbol, a passing sector information, an aircraft type, and the like.

The SSR data file 49 records the SSR data provided from the radar site 7 for each aircraft. As illustrated in FIG. 6, the SSR data includes an aircraft number, position coordinates, reception time, speed, current altitude, indicated altitude, altitude change rate, and the like. SSR
Data file 49 is a new SS from radar site 7.
Each time R data arrives, it is added (or updated).

In the message item table 51, items to be incorporated in the control message (that is, components of the control message) are registered, for example, in the form of a text code. Here, the item of the control message is, for example, a message code indicating the type of the message (for example, “CONTACT”, “AREAQ” described later).
NH "," TRAFFIC ", etc., and numeric / character parameters included in the message (for example," NORTH "," SOUTH "indicating the traveling direction described later," CLIMBING "indicating the ascending / descending," DESCENDIN "
G ", aircraft model name, etc.), a parameter code indicating a type of parameter (for example,"O'CLOCK"meaning a relative direction described later," BOUN meaning a traveling direction "
D "and" MILES "meaning relative distance). The message editing unit 53 generates a control message by extracting necessary items from the message item table 51 and putting the items into a message format.

Next, the operation of generating a control message under the above configuration will be described. First, the operation of generating a frequency change instruction message will be described.

FIG. 7 shows the structure of the frequency change instruction message. Following the header 71 is the body of the message. In the text, a fixed message code 73 meaning a frequency change instruction message of "CONTACT", two parameters, that is, a control institution call code 75 indicating a control institution controlling the inheritance area, and a successor The area frequency 77 is included. For example, in the case of Fukuoka ACC, "FUKUOKA"
CONTROL ”or“ TOKYO ”at Haneda Airport
APPROACH "and the like. Although not shown, the header 71 includes a control organization call code of a control organization that controls the transfer-side area that is the transmission source of the control message, the identification of the aircraft to which the control message is transmitted, and the like.

FIG. 8 shows a processing flow of the RDP system 3 when generating the frequency change instruction message.

As described above, the frequency change instruction message is issued from the transfer-side control agency at the time of control transfer. When the processing by the hand-accept processing unit 31 for control transfer is completed normally (S21), the frequency change message unit 53 is activated to start editing processing (S2).
2). First, the frequency change message section 53 reads the message code “CONT” from the message item table 51.
ACT ”is read and set in a message code field (not shown) of the message on the memory (S2).
3). Next, from the "ACPT" message received from the successor side at the time of the hand-accepting process, the inheritance-side control organization call code is extracted and set in the control organization call code field of the message (S24). Next, the frequency of the inherited area is read from the frequency / main QNH table 45, and is set in the frequency field of the message (S25). Further, the identification of the target aircraft is set in the destination field (not shown) of the header on the memory (S26). Since the frequency change instruction message as shown in FIG. 7 has been completed, the transmitting unit 43 is requested to transmit the message. The transmission unit 43 reads out the frequency change instruction message from the memory and wirelessly broadcasts it to the aircraft (S27).

FIG. 9 shows a flow of processing for generating a frequency change instruction message in a control transfer case different from the above.
In other words, when an aircraft attempting to land at a destination airport is transferred to the airport, or when the control and communication facilities at the airport are poor, the above-described automatic hand-accept procedure by inter-system communication cannot be performed. FIG. 9 shows a process of generating a frequency change instruction message in such a case.

In this case, when the control transfer to the destination airport is completed, the controller on the transfer side inputs a frequency change instruction from the PVD 21 (S31). Then, the frequency change message unit 53 is activated to start the editing process (S3).
2). First, the frequency change message unit 53 sets the message code “CONTACT” in the message code field of the message on the memory as in the case of FIG. 8 (S33). Next, the flight plan file 47 of the target aircraft is searched using the aircraft number of the target aircraft as a key, and the control agency calling code of the destination airport (the destination airport symbol shown in FIG. 5) is obtained from the flight plan file 47. This is set in the control system call code field of the message (S34). Subsequent processing is the same as in FIG.

Next, the operation of generating a QNH change instruction message will be described.

FIG. 10 shows the structure of a QNH change instruction message. After the header 81, the body of the message follows. In the text, QNH "AREA QNH"
A fixed message code 83 indicating that the message is a change instruction message, and a QNH value 85 as a parameter are included. As described above, the header 81 includes a control institution calling code of the control institution of the transmission source, identification of the aircraft of the transmission destination, and the like.

There are three cases where a QNH change instruction message is issued.

At the time of control transfer, if the target aircraft is flying at an altitude of less than 14,000 feet, the aircraft is notified of the main QNH value of the area on the successor side.

In the area, an aircraft descending from an altitude of 14,000 feet or more to less than 14,000 feet according to a descent instruction from a controller is notified of a main QNH value of the area.

When the main QNH value of the area is changed, all aircraft flying in the area at an altitude of less than 14,000 feet are notified of the changed main QNH value of the area.

FIG. 11 shows a processing flow for generating a QNH change instruction message at the time of the above control transfer.

As shown in FIG. 8, the hand
When the accepting process is completed (S41), first, a process of editing and transmitting a frequency change message is performed (S4).
2). Subsequently (or in parallel with S42), the QNH change message unit 55 is activated to start editing the QNH change instruction message (S43). First, the QNH change message unit 55 searches the SSR data file 49 of the target aircraft using the number of the target aircraft as a key, reads the current altitude of the target aircraft from the file, and finds that the current altitude is 1
It is determined whether it is less than 4,000 feet (S44). As a result, if it is 14,000 feet or more, the process ends, but
If less than 14,000 feet, do the following: That is, first, the message code “AREA QNH” is read from the message item table 51 and set in the message code field of the message on the memory (S45). Next, the main QNH value of the successor area is read from the frequency / main QNH table 45, and is set in the QNH value field of the message (S46). Next, the destination field of the header on the memory (not shown)
Is set to the identification of the target aircraft (S47). Since the QNH change instruction message as shown in FIG. 10 has been completed, the transmitting unit 43 is requested to transmit the message. The transmitting unit 43 reads the QNH change instruction message from the memory and wirelessly broadcasts it to the aircraft (S4).
8).

FIG. 12 shows a processing flow for generating a QNH change instruction message at the time of descent according to the descent instruction from the controller.

When a descent instruction is issued from the controller, D
When the local commanded altitude change processing is performed by the CU 23, a completion notification is received from the DCU 23 when the commanded altitude change processing is completed (S51). When the altitude change processing is completed, a completion notification is sent from the FDP system 13 (S52). In any case, when you receive the completion notification,
The QNH change message unit 55 is activated and starts editing of the QNH change instruction message (S53). First, the QNH change message unit 55 searches the SSR data file 49 of the target aircraft using the number of the target aircraft as a key, reads out the current altitude before and after the instruction to descend the target aircraft and the indicated altitude from the file, and based on them. Then, it is determined whether the descent of the target aircraft by the descent instruction is to lower the altitude from 14,000 feet or more to less than 14,000 feet (S54). As a result, the process is terminated if it does not correspond to such a descent, but if it does, the following process is performed. That is, first, the message code “AREA QNH” is read from the message item table 51.
Is read and set in the message code field of the message (S55). Next, the main QNH value of the area is read from the frequency / main QNH table 45 and set in the QNH value field of the message (S5).
6). Subsequent processing is the same as in FIG.

FIG. 15 shows the flow of processing for generating a radar traffic information message.

As described above, the DCU 23 detects the approach of an aircraft and issues a CNF notification. This notice is sent to CN
The F notification reception processing unit 39 receives and extracts the number of the approaching aircraft from the notification (S71). Subsequently, the radar traffic information message unit 57 is activated, and searches the SSR data files 49 of the own aircraft and the other aircraft from the extracted numbers of the target aircraft (hereinafter, one is the own aircraft and the other is the other aircraft). Based on the SSR data in the file, a route direction editing process (S72), an approach distance editing process (S76), a progress method editing process (S78), and a radar traffic information message editing process (S81) are executed. Steps S72 to S72
In the process of 87, the radar traffic information message unit 57 reads out the message code, the parameter code, and the parameter as shown in FIG. 14 from the message item table 51 and sets them in the corresponding fields of the message. Then, I will not explain each time to avoid complication.

In the course direction editing process (S72), the radar traffic information message unit 57 first calculates the course of the own aircraft and the course of the other aircraft (S73, S74), and based on the courses of the two aircraft, the other routes are viewed from the own aircraft. The route direction of the aircraft is determined, and the numerical value (1 to 12) of the route direction is set in the corresponding field of the message (S75). In the next approach distance editing process (S76), first, the distance between the own aircraft and the other aircraft at the time of closest approach is calculated based on the course of both aircraft (S77), and this distance is set in the corresponding field of the message (S78). . In the subsequent traveling direction editing process (S79), the traveling direction of another device is calculated (S8).
0), this is set in the corresponding field of the message (S81).

In the last radar traffic information message editing process, the type of the other aircraft obtained from the SSR data, the current altitude, whether the vehicle is ascending or descending from the current altitude and the indicated altitude, and the indicated altitude are set in the corresponding fields of the message. It is set (S83-S86). Subsequently, the identification of the own device is set in the header (S87). This completes the radar traffic information message. The transmitting unit 43 reads out this message from the memory and broadcasts it.

Further, the radar traffic information message section 57
, Regarding the once sent radar traffic information message,
A transmitted flag on the memory indicating that it has been transmitted is set (S88). As long as the transmitted flag is set, the radar traffic information message is not duplicated based on the same CNF notification as the message. When a CNF release notification for the CNF is received from the DCU 25, the transmitted flag is reset.

The processing from step S72 onward is repeated one more time, with the two aircraft approaching each other swapping their own aircraft and the other aircraft.
