Description

[0001]
TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an airfield light monitoring and control system that performs light control on a taxiway centerline installed on a taxiway that is an airport facility.
[0002]
[Prior art]
The light monitoring and control system at the airport is a part of a visual aid facility for ensuring the safety of aircraft navigation, and controls lighting (adjustable brightness) and turning off the taxiway centerline lights arranged on the taxiway. By doing so, it has a role of instructing whether or not the travel route of the aircraft traveling on the taxiway is acceptable.
[0003]
In particular, this type of monitoring and control system is one of the indispensable systems for operating an airfield during low visibility (when visibility is poor such as rainfall or dense fog), and controls the turning on and off of the taxiway centerline light. Requires reliability and certainty. Therefore, the operation of the air traffic controller is strictly strict because the light monitoring and control system may cause a pointing error or malfunction, which may cause a near-miss accident or a collision accident on the aircraft. It is necessary to give appropriate instructions such as turning on / off the light based on proper judgment, and the situation is very severe from a mental point of view.
[0004]
The lighting control at each airfield mainly includes the runway-side lighting control during aircraft landing, and guidance when traveling from the apron (terminal) toward the runway and taking off, and when traveling toward the apron after landing on the runway. It is divided into roadside lighting control, and the number of lighting devices varies depending on the size of the airport, but it can be hundreds to tens of thousands, and it is natural that the traffic controller performs monitoring, judgment, determination, operation, etc. There is a limit.
[0005]
Normally, the controller controls the airfield lighting monitoring and control system by: (1) the operation direction of the aircraft at the time of landing, (2) the background luminance during the day, dusk, and night, and (3) the height of the cloud is, for example, 1000 m or more. , 4) While judging the four conditions consisting of the visibility described above, select and operate one of each condition using the operation switch to guide the user to the optimal brightness suitable for the current environment. Controls the lighting status of road centerline lights.
[0006]
For example, if the background luminance is daytime, visibility is poor, or the cloud base is low, control is performed to brighten the lights of the taxiway centerline lights.On the other hand, the background luminance is night, visibility is good, and the cloud base is high. Then, control to darken the lamp is performed. The pilot navigates or drives the aircraft while watching the lighting conditions.
[0007]
However, the pilot operating the aircraft is traveling on the taxiway based only on the information on the on / off state of the taxiway centerline light installed on the taxiway, but the controller judges the above four conditions. While turning on or off all the taxiway centerline lights. Therefore, the pilot operating the aircraft determines that the taxiway is running when all the taxiway centerline lights are on, and determines that the vehicle is not running if all taxiway centerline lights are off. , You will run the aircraft.
[0008]
This means that the pilot operating the aircraft cannot judge the correct traveling direction and the safe traveling route of the aircraft on the taxiway from the above on / off state of the taxiway centerline light. In other words, the pilot navigates or travels on the aircraft by receiving an instruction of a correct traveling direction of the taxiway or a safe traveling route by a voice instruction from the controller by radio. As a result, while the burden on the controller is increasing, the pilot operating the aircraft cannot determine which traveling direction or which traveling route is safe, and the situation is confusing at present.
[0009]
In view of the above situation, the following aircraft guidance device has been proposed.
[0010]
This aircraft guidance device includes a plurality of lighting devices embedded in the guidance route of the aircraft, means for storing a plurality of guidance routes for guiding each aircraft to a target position, and reception of radio waves transmitted from GPS satellites. A plurality of antennas installed along a guidance route to be performed, and a second guidance route to another aircraft preceding the guidance route of the aircraft when a first guidance route for the aircraft is selected from the storage means. It is determined from the information of the aircraft position detecting means by the antenna whether there is a preceding aircraft in the common part with, and among the lighting devices on the first guidance route, the lighting device between the preceding aircraft and the succeeding aircraft (For example, see Patent Document 1).
[0011]
[Patent Document 1]
JP-A-8-166946.
[0012]
[Problems to be solved by the invention]
However, the following problems have been pointed out in the aircraft guidance apparatus described above.
[0013]
{Circle around (1)} A large number of lighting devices and receiving antennas must be installed in pairs along each guide route, and the equipment cost is extremely high.
[0014]
{Circle over (2)} Since the position information of the aircraft is collected from a large number of antennas installed along each guidance route, a very complicated structure is required to finally control the lighting and extinguishing of each lighting device.
[0015]
(3) The lighting device installed along the guidance route is a lighting device corresponding to a general taxiway light installed at the edge of the guidance route, etc. It has a role of instructing whether or not the travel route is available, and aircraft monitoring tends to become more and more complicated.
[0016]
The present invention has been made in view of the above circumstances, it is possible to automatically use the taxiway centerline light to effectively indicate the traveling direction and a safe traveling route, and thus greatly reduce the burden on the controller, It is an object of the present invention to provide an airfield light monitoring and control system that provides appropriate instructions to a pilot operating an aircraft.

[0019]
The present invention is configured as described above, and always turns on the taxiway centerline lights in front of the aircraft based on the information during aircraft detection from the aircraft detection sensors installed for each safety section, behind the aircraft By turning off the taxiway centerline lights in at least one safety section, the taxiway centerline lights are effectively used, and a low-cost, simple control configuration always provides a safe driving route. It is possible to guide the aircraft while securing.

It is possible to control turning on and off of the lamp group.
[0021]
When the taxiway centerline lights are turned on at a high speed in a predetermined order, it is possible to instruct the traveling direction of the aircraft and a safe traveling route, greatly reducing the burden on the controller, It is possible to avoid confusion.
[0022]

The aircraft can be driven in accordance with the route instruction, and the burden on the controller can be greatly reduced, and the pilot who operates the aircraft can be driven safely without confusion.
[0023]
(3) Further, the airfield light monitoring and control system according to the present invention can be similarly applied to a taxiway light group installed on one side or both sides of the taxiway instead of the taxiway centerline light group.
[0024]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0025]
(Embodiment 1)
FIG. 1 is a configuration diagram showing an embodiment of an airfield light monitoring and control system according to the present invention.
[0026]
In FIG. 1, reference numeral 1 denotes a taxiway that guides an aircraft from an apron toward a runway and guides an aircraft from the runway toward an apron. The taxiway 1 includes a leading aircraft 2 and a succeeding aircraft 3 Are set at predetermined intervals along the taxiway 1 from the viewpoint of ensuring safe traveling between the aircrafts.
[0027]
A number of taxiway centerline lights 2 are arranged substantially on the centerline of the taxiway 1, but for convenience of explanation, a plurality of taxiway centerlines are provided for each of the safety sections 4a, 4b, 4c, 4d,. The lights are arranged in groups 5a, 5b, 5c, 5d,.
[0028]
Further, aircraft detection sensors 6, 7, 8,... Are installed on the boundary lines between the adjacent safety sections 4a-4b, 4b-4c, 4c-4d. The aircraft detection sensors 6, 7, 8,... Include, for example, a method of detecting the passage of an aircraft using a radio wave as a medium or a method of detecting the passage of an aircraft using a transmission and reception of an optical signal as a medium. It is possible to detect the passing state of the aircraft using the medium.
[0029]
The output terminals of the aircraft detection sensors 6, 7, 8,... Are connected to the light monitoring control processing unit 12 via detection signal lines 9, 10, 11,. The light monitoring control processing unit 10 is a device that performs light control of the taxiway centerline lights 5a, 5b, 5c, 5d,... Based on the outputs of the aircraft detection sensors 6, 7, 8,. Are connected to the respective taxiway centerline lamp groups 5a, 5b, 5c, 5d,... Via lines 13, 14, 15, 16,.
[0030]
As the lamp monitoring control processing unit 12, for example, a computer having a CPU, a hard relay, a logic control device having a logic element, and the like are used.
[0031]
The light monitoring control processing unit 12 is functionally configured so that, at predetermined intervals, the condition presence / absence information based on the selection of the above-mentioned four conditions, for example, the predetermined conditions, and the output of the aircraft detection sensors 6, 7, 8,. , And a lamp determining unit that determines whether each of the taxiway centerline lamp groups 5a, 5b, 5c, 5d,... Is turned on or off based on the information collected by the information obtaining unit. A lamp for selectively supplying power to each taxiway centerline lamp group 5a, 5b, 5c, 5d,... Arranged in each of the safety ensuring sections 4a, 4b, 4c, 4d based on the judgment result by the judging means. Control means are provided.
[0032]
Next, the operation of the above-mentioned airport light monitoring control system will be described.
[0033]
First, when the controller is confirmed to be safe when the aircraft travels from the apron to the runway or from the runway to the apron, four conditions are set by the operation switch ((1) take-off and landing operation direction when the aircraft lands, (2) ▼ Background luminance during daytime, dusk, nighttime, etc., (3) Cloud height of, for example, 1000 m or more, below cloud height, (4) Visibility) Outputs lighting condition satisfaction information. At this time, the lights are controlled so that the taxiway centerline lamp groups 5a, 5b, 5c, 5d,... Have the optimum brightness according to the current external environment.
[0034]
Here, the information acquisition means of the light monitoring control processing unit 12 fetches information on the presence / absence of establishment of guideway centerline light conditions and the outputs of the aircraft detection sensors 6, 7, 8,. Thereafter, the lamp determining means is executed. When the aircraft 3 is in the position state shown in FIG. 2A, that is, the acquired taxiway centerline lamp lighting condition establishment information is condition establishment information. , 7 and 8, it is determined that traveling on the taxiway 1 is safe, and the light control means is executed.
[0035]
When the light control means receives from the light judgment means that the judgment that the traveling of the aircraft 3 is safe is made, each taxiway centerline light arranged in each of the security sections 4a, 4b, 4c, 4d,. Power is supplied to all the groups 5a, 5b, 5c, 5d,... To light them (see FIG. 6B). When the taxiway centerline lamp groups 5a, 5b, 5c, 5d,... Are turned on, they are sequentially turned on in the direction of..., 5d, 5c, 5b, 5a in order to indicate the traveling direction of the aircraft 3. That is, the taxiway centerline lamp group 5d is sequentially turned on from the left side to the right in the drawing, and when all the taxiway centerline lamp groups 5d are turned on, the taxiway centerline lamp group 5c is similarly turned on from the left side in the drawing. The lights are sequentially turned on in the right direction, and the taxiway centerline lamp groups 5b and 5a are turned on in the same manner.
[0036]
By the way, as shown in FIG. 3A, when the preceding aircraft 2 exists in front of the aircraft 3, the preceding aircraft 2 approaches the safety securing section 4 a from the security securing section 4 b, and the aircraft detection sensor 6 detects the aircraft. Information is transmitted to the light monitoring control processing unit 12 through the detection signal line 9.
[0037]
Accordingly, the information acquisition means of the light monitoring control processing unit 12 includes information indicating that the conditions for lighting the taxiway centerline lights are satisfied, information indicating that the aircraft is being detected by the aircraft detection sensor 6, information indicating that the aircraft is being detected, as shown in FIG. , 8, the light determining means determines that it is dangerous for the subsequent aircraft 3 to travel from the security section 4 d to the safety section 4 c ahead, and after the aircraft detection sensor 6 detects the aircraft. It is determined that the taxiway centerline lamp groups 5b and 5c installed in the safety sections 4b and 4c are turned off, and the taxiway centerline lamp groups 5a and 5d installed in the safety sections 4a and 4d are turned on. The control means supplies power to the taxiway centerline lamp groups 5a and 5d to light them. At this time, an instruction is given to each taxiway centerline lamp group 5a by sequentially lighting at high speed from the left side to the right side in the drawing to drive in the lighting direction, that is, to instruct the taxiway to run in the running direction of the aircraft 2. Can be put out. Further, it is possible to instruct the pilot operating the aircraft that the sequential lighting direction of each taxiway centerline lamp group 5a is a safe traveling route.
[0038]
Further, the light judging means of the light monitoring control processing unit 12 judges the presence or absence of an aircraft, and when the aircraft 2 approaches the safety ensuring section 4a, the taxiway center line based on the aircraft detection information from the aircraft detection sensor 6. Since the light groups 5b and 5c are turned off and only the lights 5a and 5d are turned on, it is possible to always secure at least one safety section 4c between the preceding aircraft 2 and the succeeding aircraft 3. That is, even when the aircraft 3 travels, the taxiway centerline lights 5d before the safe section (safety securing section 4d) and the taxiway centerline lights 5a in front of which the aircraft 2 is running are lit. Thus, at least one safety section can be reliably ensured.
[0039]
As a result, by automatically turning on and off the taxiway centerline lights, the traveling direction of the aircraft 2 and the safe traveling route are automatically instructed, so that the burden on the controller can be greatly reduced and the aircraft is operated. The pilot only has to drive the aircraft in the direction of its lighting, without causing confusion.
[0040]
(Embodiment 2)
FIG. 4 is a configuration diagram showing another embodiment of the airfield light monitoring and control system according to the present invention.
[0041]
In this embodiment, even when two taxiways intersect and an aircraft is present on each taxiway, a safety section is ensured, and the traveling direction and the traveling route can be securely specified. It is an example.
[0042]
In the figure, reference numeral 21 denotes an A taxiway, 22 denotes a B taxiway, and an intersection section 23 is set at a portion where the A taxiway 21 and the B taxiway 22 intersect. Reference numeral 24 denotes an aircraft traveling on the taxiway A 21, and reference numeral 25 denotes an aircraft traveling on the taxiway B 22. Each of the A taxiway 21 and the B taxiway 22 is provided with a safety section for each predetermined distance as in FIG.
[0043]
The normal taxiway centerline lamps are arranged along the centerline of the taxiway A, and a plurality of taxiway centerline lamps 26 and 27 are provided for each of the safety sections and the intersection 23. , 28, 29, 30 are arranged, and also in the B taxiway 22, a plurality of normal taxiway centerline lamp groups 31, 32, 33, 34, 35 are provided for each safety section and at the crossing section 23. Are arranged.
[0044]
Further, in the intersection section 23, the intersection guideway centerline lamp groups 36, 37, 38, and 39 are arranged such that the guideway A 21 and the guideway B 22 bridge each other.
[0045]
In addition, aircraft detection sensors 41, 42, 43, and 44 are installed on the boundary lines of the safety assurance sections on the A taxiway 21 side between the A taxiway 21 and the B taxiway 22; Aircraft detection sensors 45, 46, 47, and 48 are provided on the boundary line of each safety section.
[0046]
The output terminals of the aircraft detection sensors 41 to 48 are connected to the light monitoring control processing unit 12 via detection signal lines 51, 52, 53, 54, 55, 56, 57, 58,. The light monitoring control processing unit 12 is a device that controls the lights of the taxiway centerline lights 26 to 39 based on the outputs of the aircraft detection sensors 41 to 48,. Are connected via control signal lines 61 to 74,.
[0047]
The lamp monitoring control processing unit 12 is functionally configured such that a normal taxiway centerline lamp group (26, 27, 28, 29, 30) based on four conditions selected by a controller or the like described above at predetermined intervals, or Information obtaining means for collecting the lighting conditions of (31, 32, 33, 34, 35) and the outputs of the aircraft detection sensors 41 to 48, and each guideway center based on the information obtained by the information obtaining means. A light determining means for determining whether the line light group is turned on or off, and a light control means for selectively supplying power to each taxiway centerline light group based on a result determined by the determining means are provided. ing.
[0048]
Next, the operation of the above-mentioned airport light monitoring control system will be described.
[0049]
First, when the airplane goes from the apron to the runway or from the runway to the apron, when the controller etc. is confirmed to be driving safe, when one of the four conditions is selected by operating switches, the taxiway center line Outputs lighting condition satisfaction information. At this time, the lighting control is performed so that the taxiway centerline lamp group has the optimum brightness according to the current external environment.
[0050]
Here, the information acquisition means of the light monitoring control processing unit 12 takes in information on whether or not the conditions for lighting the taxiway centerline lights are satisfied and the outputs of the aircraft detection sensors 41 to 48 at predetermined intervals. After that, the lamp judgment means is executed.
[0051]
Here, the light determining means receives information on whether or not the condition of the taxiway centerline lamp is satisfied and information on whether or not the aircraft has been detected by the aircraft detection sensors 41 to 48. For example, the aircraft 24 is placed on the A taxiway 21 just before the intersection 23. Exists on the taxiway B 22 in front of the intersection 23, and the aircraft 24 on the taxiway A on the taxiway B on the taxiway A based on the controller or predetermined information. In the case where the vehicle travels with priority over the 22 aircraft 34, the following determination processing is executed.
[0052]
That is, as shown in FIG. 5, the lighting determining means determines whether the lighting condition establishment information of all the taxiway centerline lights 26 to 39 by the selection of each of the four conditions, the information of the aircraft being detected by the aircraft detection sensor 44, and the other aircraft It is determined that the taxiway centerline lamps 29, 37, 32, and 31 are turned on on the condition of the aircraft non-detection information from the detection sensors 41 to 43 and 45 to 48, and the corresponding taxiway centerline lamps are turned on according to the traveling direction. High-speed lighting control is sequentially performed. At this time, for the aircraft 25 existing on the taxiway B, the intersection section 23 is secured as at least one safety section, and even if the aircraft 25 travels, the taxiway in the safety securing section existing on the aircraft 25 is provided. Only the center line lamp 34 is turned on, and the group of guideway center line lights in the intersection section 23 connected to the safety ensuring section is in an extinguished state.
[0053]
In the above state, the traveling direction of the aircraft 24 and the safe traveling route are instructed by the lighting and the sequential lighting of the taxiway centerline lights 29, 37, 32, 31. Turn left and enter the taxiway B. However, the taxiway centerline lights 32 between the aircraft detection sensor 45 and the aircraft detection sensor 46 are turned off unless the aircraft detection sensor 45 outputs the information indicating that the aircraft is detected. do not do. This is because a safe section cannot be secured. Here, when the aircraft 24 passes through the safety ensuring section between the aircraft detection sensor 45 and the aircraft detection sensor 46 and outputs aircraft non-detection information from the aircraft detection sensor 45, the taxiways arranged in the traveling direction of the aircraft 25 The centerline lamp group 33 controls the lighting, and it is possible to enter the intersection 23. In this case, a safety section between the aircraft detection sensor 45 and the aircraft detection sensor 46 is a safety section.
[0054]
Therefore, according to the above-described embodiment, the presence or absence of an aircraft is determined from the aircraft detection presence / absence signals of the aircraft detection sensors 41 to 48 for each safety section set along the two intersecting taxiways 21 and 22. Even if the aircrafts 24 and 25 are present on the two taxiways 21 and 22, respectively, the required taxiway centerline light is always secured while securing one safety section under the predetermined priority of the aircraft. Since the groups are sequentially turned on at high speed in the traveling direction, even if the aircrafts 24 and 25 are present on the taxiways 21 and 22, respectively, a safe section between the aircrafts traveling on the taxiway is ensured, and the correct driving route instruction is followed. The aircraft can be driven, and the burden on the controller can be greatly reduced, and the pilot can be safely driven without causing confusion for the pilot operating the aircraft.
