Description

  The present invention relates to a ground travel guidance support system that supports safe ground travel of an aircraft running on a taxiway and an aircraft after landing on a runway.

  The ground driving guidance support system is a part of visual assistance equipment for the purpose of aircraft safety and smooth ground driving. Stop line lights, guide guidance lights, etc. are installed, and for each aircraft present on the runway and taxiway, automatic monitoring and control is performed for lighting and extinguishing of each light according to a preset travel route, Realizes safe and smooth ground travel.

  Conventional ground driving guidance support systems include position detection means such as monitoring radars and aircraft detection sensors for detecting the current position of an aircraft existing on an airfield runway and a taxiway, and aircraft detected by the position detection means. Travel route setting means for setting a travel route from the current position to the destination based on the current position and the destination, and according to the set travel route, the current position of the aircraft detected by the position detection means And a visual check of the airfield by the controller gives guidance instructions such as a direction of travel and a stop instruction by each lamp to the corresponding aircraft (Patent Document 1).

  By the way, in the ground driving guidance support system as described above, operators (including air traffic controllers) who are involved in the operation of the airfield give guidance instructions to the aircraft, so at low visibility (at night, rainfall, Problems with the operation of poor visibility such as dense fog.

  The operation at low visibility is based on the current position information and visual confirmation of the aircraft in the airfield, and the controller gives necessary guidance instructions to the aircraft traveling on the ground via the light control. Monitors the surrounding conditions, including the aircraft that is running according to the set travel route, and judges, determines, and instructs (transmits) the contents of the instructions, so the burden on the controller is heavy and the aircraft can run smoothly on the ground The situation is difficult to do.

  Therefore, incomplete instructions could cause aircraft near miss accidents and collision accidents, and the operations of operators, including air traffic controllers, who are involved in airfield operations, are extremely intense mentally. Yes.

  Usually, airfield lighting monitoring control is mainly for the runway for landing aircraft, aircraft that run from the apron (terminal) to the runway, and run to the apron after landing on the runway The number of lights varies depending on the airport, but it ranges from hundreds to tens of thousands. As a result, there is a limit to the operations of the controller, such as monitoring, judgment, determination, and operation (instruction) of instruction contents.

  Airfield lighting monitoring control by the controller is as follows: “1” Runway operation direction when landing on the aircraft, “2” Background brightness during daytime, dusk, nighttime, etc. “3” Cloud height is 1000 m or more, for example, Cloud height, "4" Judgment of the four conditions consisting of the above-mentioned visibility, and selecting one with each operation switch for each condition, the taxiway center line so as to obtain the optimum brightness according to the current surrounding environment Control the lighting condition of the light.

  For example, when the background brightness is `` daytime '', `` low visibility '', or `` low cloud base height '', control is performed to brighten the taxiway centerline lamp, and conversely, the background brightness is `` night '', `` When the visibility is good and the cloud bottom height is high, control is performed to darken the taxiway centerline lamp. Accordingly, the pilot is navigating or running the aircraft while watching the lighting conditions.

The lights are controlled.

  However, since the aircraft 16 after landing enters the vicinity of the highway departure guideway 13 connected to the runway 11 at high speed, the pilot waits for a guidance instruction from the controller and enters the next traveling direction or stop. In addition, as described above, in the case of operation control at low visibility by the controller, it becomes a very dangerous state. That is, when the aircraft 17 is present on the taxiway 12 on the near side of the high-speed departure taxiway 13, if the aircraft 16 after landing enters the high-speed departure taxiway 13 at a high speed, the aircraft 17 is in front of the high-speed departure taxiway 13. When the aircraft 17 is present on the side taxiway 12, the risk of collision is extremely high.

  The present invention has been made in view of the above circumstances, and implements lighting control for avoiding a collision between an aircraft after landing on a runway and an aircraft running on a taxiway, taking advantage of the visual assistance function from the aircraft, and performing ground control. It is an object of the present invention to provide a ground driving guidance support system that reduces the duties of the controller who controls the vehicle and ensures further safety of ground driving.

  In order to solve the above-described problems, the present invention provides at least a high-speed departure guideway between a taxiway and a runway, and monitors the taxiway centerline lamp installed on the taxiway and controls the light while controlling the lamp. A first aircraft on the road is guided to the runway side, and a second aircraft that has landed on the runway is monitored on the runway side while monitoring and controlling the runway light on the runway. A ground traveling guidance support system for guiding, wherein a stop line lamp installed so as to cross the runway boundary portion of the high-speed departure guidance road, and a first on the guidance road on the front side of the high-speed departure guidance road When the first aircraft is present and the landed second aircraft is traveling at a high speed on the runway on the near side of the high-speed departure guideway, the stop line light is turned on and the second aircraft is turned on. To the high-speed departure taxiway A configuration in which a monitoring control means for prohibiting the entry.

  In addition, the present invention is a new roadway mark that represents the roadway of the second aircraft that has landed on the side of the runway that is located on the front side of the high-speed departure guideway. An entry prohibition indicator having an entry prohibition mark display portion arranged on the side of the traveling road mark that is not allowed to enter is provided, and the entry prohibition mark display portion of the entry prohibition indicator is displayed when the monitoring control means lights the stop line light. The lighting control is performed so as to avoid collision between the aircraft after landing on the runway and the aircraft traveling on the taxiway by turning on and indicating that entry is impossible.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a configuration diagram showing an embodiment of a ground travel guidance support system according to the present invention.

  The ground travel guidance support system is roughly composed of a ground lighting facility system 1 and a light monitoring control system 2.

  As in FIG. 4, the ground lighting equipment system 1 is provided with a high-speed departure guideway 13 and a connection guideway 14 between the runway 11 and the taxiway 12, and the runway 11 extends along the runway center line. The runway center line lamps 21,... Are installed, and the taxiway center line lamps 22,.

  The high-speed departure taxiway 13 is a taxiway for the aircraft 16 that has landed on the runway 11 to leave the runway 11 and enter the taxiway 12, and the taxiway centerline lamp 22a is along the centerline. ,... Are installed, and further, stop line lights 23 are installed at the boundary with the runway 11.

  In addition, on the runway 11 and the taxiway 12, an aircraft detection sensor (not shown) is installed for each predetermined section, and the current position information of the aircrafts 16 and 17 is acquired when passing through the boundary of each adjacent section. In this configuration, the data is transmitted to the monitoring control device 31 described later by wireless communication or wired communication.

  Further, on the side of the runway 11 on the front side of the high-speed departure guideway 13, there is provided an entry prohibition indicator 24 that makes it impossible for the aircraft 16 after landing to enter the high-speed departure guideway 13. The entry prohibition indicator 24 includes a travel path mark 24a representing the travel path of the aircraft 16 that has landed, and an entry prohibition mark display portion that is lit and displayed in red, for example, with a red mark on the travel path mark 24a that is not allowed to enter. 24b. For example, as shown in FIGS. 2A to 2D, there are several display forms.

  As the lighting monitoring control system 2, a monitoring control device 31 that performs a guidance instruction regarding lighting is connected to an airport surface radar 33 and at least one lighting control device 34 via a transmission LAN 32. Each lighting control device 34 is connected to at least one relay transmission device 36 via a control LAN 35.

  The relay transmission device 36 is connected to a power line 38 that is annularly connected to the output side of a constant current control power supply (CCR) 37 via a rubber transformer 39 c, and the lamp received from the monitoring control device 31 via the lamp control device 34. A control command is superimposed on the power line 38 via the rubber transformer 39c and conveyed.

Each rubber transformer 39 ₁ to the power line 38, which is cyclized, 39 _2, ..., 39 _n-20, terminal controller ₄₀ 1 via the _{..., ..., 40 n-20} , ... are connected, the ground lighting equipment Control of turning on / off the taxiway center line lamp 22 and the like constituting the system 1, and the rubber transformers 39 ₁ ,..., 39 _n-20 ,. The data is transmitted to the monitoring control device 31 via the control device 34.

  The supervisory control device 31 determines a travel route of each aircraft based on the input unit 31A such as a keyboard, a mouse, and an operation switch for the controller to input an operation instruction related to safe traveling of the aircraft, and the operation plan information, and A monitoring console that outputs a light control command based on the rough position of the image data of the aircraft captured by the airport surface radar 33 installed in the airport and the current position information of each aircraft from the aircraft detection sensor described above. 31B and a display unit 31C for displaying each aircraft based on the current position information are provided in the simulation model of the entire airfield.

  Next, the operation of the ground travel guidance support system configured as described above will be described.

  Conventionally, the travel route from the apron to the take-off location of the aircraft 17 of the flight number is automatically set based on the operation plan information related to the flight number of each aircraft.

Therefore, the monitoring control unit 31 in accordance with the automatic traveling path, the current position information of the airport ground radar 33 and aircraft detection aircraft from the sensor 17, terminal controller _{40 1, ..., 40 n-} 20, ..., up from 40 _n A lighting control command is output from the monitoring console 31B based on the lighting information of the coming taxiway center line lamps 22,.

  Incidentally, when the landing aircraft 16 is traveling at a high speed on the runway 11 on the near side of the high-speed departure guideway 13, the aircraft 17 existing on the guideway 12 is prevented from entering the runway 11 from the connection guideway 14. The stop line lamp 15 is turned on, or the landing aircraft 16 is prevented from entering the high-speed departure guide path 13 when the stop line lamp 15 is turned on.

  However, at low visibility, which is difficult for the controller to check sufficiently, if the aircraft 16 immediately after landing is traveling at high speed on the runway 11 and a guidance instruction delay or instruction error by the controller occurs, a high-speed departure guidance path There is a risk of entering 13 and colliding with the aircraft 17.

Therefore, the monitoring control device 31 operates according to the processing flow as shown in FIG.
The supervisory control device 31 acquires aircraft position information from an aircraft detection sensor or the like installed on the taxiway 12, and the aircraft 17 is displayed at a corresponding position on the taxiway 21 displayed on the display unit 31C. The supervisory control device 31 determines whether or not the aircraft 17 is present in the vicinity of the communication guideway 14 before the high-speed departure guideway 13 (S1).

  Here, when it is determined that the aircraft 17 is present, the landing aircraft 16 takes a high-speed departure guideway based on the aircraft position information of the aircraft detection sensor installed along the runway 11 and the aircraft position information by the airport surface radar 33. It is determined whether the vehicle is traveling in front of 13 (S2). When it is determined that the aircraft 16 on the runway 11 displayed on the display unit 31C is not traveling in front of the high-speed departure guideway 13, the controller issues a lamp control command based on the automatic travel route, the position of the aircraft, and visual observation. It outputs (S3), returns to step S1 while giving a guidance instruction regarding the aircraft 17, and repeats the same processing.

  By the way, if it is determined in step S1 that the aircraft 17 is present in the vicinity of the contact taxiway 14 in front of the high-speed departure taxiway 13 and the aircraft 16 is traveling in front of the high-speed departure taxiway 13 in step S2. Then, at least the stop line lamp 23 on the high-speed departure guidance path 13 side is lit in red (S4), and control is performed so that the aircraft 16 does not enter the high-speed departure guidance path 13.

  Further, the monitoring control device 31 subsequently determines whether or not to display the inaccessibility indicator 24 (S5). When the flag to be displayed is set, for example, the X mark which is the entry prohibition mark display portion 24b of the entry impossibility indicator 24 is lit in red (S6), and then the guidance instruction is given to the aircraft 17 in the same manner as in step S3 described above. On the other hand, the high-speed traveling of the aircraft 16 is tracked, and the stop line light 15 on the connection taxiway 14 side is turned on as necessary.

  When it is confirmed that the aircraft 16 has passed through the high-speed departure guideway 13 (S8), the stop line lamp 23 and the entry impossibility indicator 24 are turned off (S9). In addition, when the stop line light 15 by the side of the communication guidance path 14 is lit, it confirms that the aircraft 16 passed the communication guidance path 14, and turns off the stop line light 15.

  Therefore, according to the embodiment as described above, when the aircraft 17 traveling on the taxiway 12 is present in the vicinity of the connecting taxiway 14 before the highway departure taxiway 13, the aircraft 16 landing on the runway 11 is high-speed. When the vehicle is present in front of the high-speed departure taxiway 13 when traveling, the stop line lamp 23 on the high-speed departure taxiway 13 side is turned on, and the no entry mark display portion 24b of the no entry indicator 24 is lit in red. Pilots can easily recognize that they cannot enter the highway departure guideway 13 by turning on the red indicator light 24b and the stop line lamp 23, and the near miss with the aircraft 17 traveling on the guideway 12 Accidents and collisions can be reliably avoided.

  Therefore, accurate visual navigation support functions for aircraft can be fully demonstrated, and as a result, the efficiency of airfield operations can be improved, and the safety of ground travel between aircraft can be sufficiently secured, reducing the duties of air traffic controllers responsible for ground control. Can greatly contribute to the development.

  In addition, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  In the above embodiment, it has been described that a series of processing operations shown in FIG. 3 are performed on the premise that the controller is at a low visibility that is difficult to be sufficiently visually confirmed. However, the aircraft 16 and the taxiway on the runway 11 are described. When the aircraft 17 on 12 is in a predetermined positional relationship, the stop line lamp 23 and the inaccessible mark display portion 24b may be lit regardless of whether or not the low visibility is present.
