All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that the terms "comprises" and "comprising," and any variations thereof, in the embodiments of the present application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. Furthermore, the terms "first" and "second", etc., are used to distinguish between different objects and are not used to describe a particular order.

The embodiment of the application provides an airport ground service vehicle passing control system and method, which can intelligently control the passing of an airport ground service vehicle at an airport intersection through the indication of a ground traffic signal lamp, thereby being beneficial to reducing the probability of the collision between an airplane and the ground service vehicle. The following detailed description is made with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present application provides a system for controlling passage of an airport ground service vehicle. As shown in fig. 1, the system may include at least: a ground traffic light array 10 including N traffic lights (e.g., traffic light 1, traffic light 2, … …, traffic light N) disposed on the ground of an early warning area of an entrance lane of an airport intersection for indicating a driving state of the entrance lane, which may include one of a passage-allowed state, a passage-prohibited state, or a passage-warning state; the system comprises an airport intersection, an entrance lane, an early warning area and a traffic lane, wherein N is a positive integer larger than 1, the airport intersection is formed by intersection of an aircraft taxiway and a traffic lane of a ground service vehicle, the entrance lane is one or any one of lanes driving to the airport intersection on the traffic lane of the ground service vehicle, and the early warning area is an area formed by a lane section from a first stop line on the entrance lane to a boundary line between the entrance lane and the airport intersection;

the airplane detector 20 is arranged on the airplane taxiway and used for detecting whether the airplane taxies on the airplane taxiway;

the signal controller 30 is respectively connected with the ground traffic signal lamp array 10 and the airplane detector 20, and is used for controlling the ground traffic signal lamp array 10 to send out a traffic prohibition light signal to indicate that the driving state of the entrance lane is a traffic prohibition state when the airplane detector 20 detects an airplane;

the signal controller 30 is further configured to control the ground traffic signal lamp array 10 to emit a traffic permission light signal to indicate that the driving state of the entrance lane is a traffic permission state when the aircraft detector 20 does not detect the aircraft; or when the aircraft detector 20 does not detect the aircraft, the ground traffic signal lamp array 10 is controlled to send out a warning traffic light signal to indicate that the driving state of the entrance lane is a warning traffic state.

In the embodiment of the application, the runway of the airport can be used for taking off or landing of the airplane. As shown in fig. 2, a plurality of taxiways may be distributed on one or both sides of the runway, and these taxiways are defined passages for taxiing airplanes within the airport. The main function of the taxiway is to provide access from the runway to the terminal area, so that the landed aircraft can leave the runway quickly without interfering with the takeoff and gliding aircraft, and the delay of the landing of the immediately arriving aircraft can be avoided as much as possible. In addition, taxiways may also be passageways that provide access to the airstrip from the terminal area when the aircraft is about to take off. The taxiways can connect different functional partitions (such as a flight area, a waiting building area, an airplane parking area, a maintenance area, a supply area and the like) so that the airport can exert the capacity potential to the maximum extent and improve the operation efficiency. The ground service vehicles serve the airport, and all the logistics services (such as oil feeding, water feeding, boarding and disembarking passengers, baggage handling, airplane dining loading, fuselage cleaning, waste disposal, etc.) during parking are the service scope of the ground service vehicles at the airport from the time the airplane enters the parking apron to the time the airplane leaves the parking apron and enters the taxiway. Due to the different services provided, the types of airport ground service vehicles are increased correspondingly, such as: refueling vehicles, luggage transport vehicles, aircraft tractors, passenger ladder vehicles, ferry vehicles and the like, so that the refueling vehicles, the luggage transport vehicles, the aircraft tractors, the passenger ladder vehicles, the ferry vehicles and the like become indispensable components of airports. The ground service vehicle has its own traffic lane at the airport, but there is an intersection between the taxiway of the aircraft and the traffic lane of the ground service vehicle, and the intersection formed by the intersection of the two can be called an airport intersection, as shown in fig. 2. Multiple airport intersections may be formed because the travel lane of a ground service vehicle may intersect multiple taxiways.

The embodiment of the application is illustrated by the distribution situation of one airport intersection. As shown in fig. 3, the traffic lane of the ground service vehicle may be divided into an entrance lane and an exit lane, and the entrance lane and the exit lane are separated by a lane isolation line. The definition of the entrance lane and the exit lane is relative to the intersection, and a lane driving to the airport intersection can be regarded as the entrance lane, and a lane driving away from the airport intersection can be regarded as the exit lane. It is to be understood that the entrance lane of one airport intersection may be the exit lane of the next airport intersection, and the exit lane of one airport intersection may be the entrance lane of the next airport intersection. The traffic lanes of the ground service vehicle may include one or more entry lanes and may also include one or more exit lanes. Because the aircraft is large in size and the engine rotates to generate certain suction when the aircraft slides, in order to ensure the safety of the aircraft and ground service vehicles, an early warning area is arranged on an entrance lane of an airport intersection, and the early warning area extends from a first stop line to a boundary line between the entrance lane and the airport intersection. The length of the early warning area can be adaptively adjusted according to actual requirements such as the size of a fuselage and the rotating speed of an engine when an airplane slides, and the length of the early warning area can be 30 meters, 50 meters, 60 meters, 80 meters or other values. A ground traffic light array 10 of a plurality of traffic lights may be disposed within the precaution area. It is understood that the ground traffic signal light array 10 may be disposed on one or any one of the entrance lanes of the airport intersection, and the ground traffic signal light array 10 may be disposed on several or any or all of the entrance lanes, which is not limited herein.

The traffic signal lamp arranged in the early warning area can be a single-side indicating signal lamp or a multi-side indicating signal lamp, such as a double-side indicating signal lamp and a three-side indicating signal lamp. When the traffic signal lamp is a single-side indicating signal lamp, a luminous indicating device is arranged on one side surface or the top surface of the traffic signal lamp, and when the traffic signal lamp is arranged on the ground, the luminous indicating device faces the direction in which a vehicle comes, so that a driver can intuitively and clearly receive an indicating light signal sent by the luminous indicating device. The light-emitting indicating device can be controlled to emit different indicating light signals, such as a traffic permission light signal for indicating that the entrance lane can pass, a traffic prohibition light signal for indicating that the entrance lane cannot pass, a warning traffic light signal for indicating that the entrance lane warns the traffic, and the like. The light emitting indicator device may be formed by combining a plurality of LED lamp beads, LED lamp strips, or graphene lamps, and may be arranged in a row or several rows, or may be arranged in a word such as "stop" or "row", which is not limited herein. When the traffic signal lamp is a multi-surface indicating signal lamp, a plurality of side surfaces of the traffic signal lamp are all provided with the luminous indicating devices, and one luminous indicating device can face the passing direction of one side of the vehicle. Each of the light emitting indicator devices may be individually controlled and may emit the same or different indicator light signals simultaneously. The multi-face indication signal lamp can be applied to driveways with variable driving directions, such as tidal driveways, and can also be applied to intersection junctions or intersections.

Alternatively, the aircraft detector 20 may include, but is not limited to, at least one of a radar sensor, a geomagnetic sensor, an infrared sensor, a laser sensor, an ultrasonic sensor, a video capture device, and the like.

In the present embodiment, at least one aircraft detector 20 may be provided on the taxiway. The aircraft detector 20 may be disposed near an entrance or exit of an aircraft taxiway, or may be disposed on a section of the aircraft taxiway, such as a middle section of the aircraft taxiway or near an airport intersection. When the aircraft enters the taxiway from the runway, the fuselage passes the aircraft detector 20, causing the aircraft detector 20 to generate a signal change to cause the aircraft detector 20 to sense the passage of the aircraft. When the aircraft detector 20 detects an aircraft, the aircraft detector 20 sends feedback information to the signal controller 30 to inform the signal controller 30 that the aircraft arrives, and the signal controller 30 sends out a control signal according to the feedback information to control the traffic lights in the ground traffic light array 10 to send out a no-pass light signal for indicating that the current driving state of the entrance lane is a no-pass state, at this time, the ground service vehicle driving on the entrance lane stops driving at the first stop line, cannot pass through the early warning area and the airport intersection, and can pass forward when needing to wait for the next pass indication. When the aircraft detector 20 does not detect an aircraft, in order to ensure stable communication, the aircraft detector 20 may report a detection result to the signal controller 30 every predetermined time (e.g., 5 seconds, 10 seconds, etc.), and the signal controller 30 may control the traffic signal lights in the ground traffic signal light array 10 to send out a traffic-permitting light signal according to the received detection result, so as to indicate that the current driving state of the entrance lane is a traffic-permitting state, and at this time, a ground service vehicle driving on the entrance lane may drive into the early warning area and the airport intersection; or the signal controller 30 may control the traffic signal lights in the ground traffic signal light array 10 to emit warning traffic light signals to indicate that the current driving state of the entrance lane is a warning traffic state, and the ground service vehicles on the entrance lane may pass according to the current actual situation, so that the driver may be warned to perform emergency treatment when an airplane comes to the intersection of the airport in case of the failure of the airplane detector 20.

Optionally, the aircraft detector 20 may be specifically configured to detect whether an aircraft is about to enter a collision area on an aircraft taxiway, where the collision area is an area formed by taxiway segments between a first reference line and a second reference line preset on the aircraft taxiway, and the first reference line and the second reference line are located on two sides of an airport intersection respectively;

the signal controller 30 is further used for controlling the ground traffic signal lamp array 10 to be adjusted to emit a traffic permission light signal from emitting a traffic prohibition light signal when the aircraft detector 20 detects that the aircraft drives away from the conflict area, so as to indicate that the driving state of the entrance lane is adjusted to be a traffic permission state from a traffic prohibition state; or when the aircraft detector 20 detects that the aircraft drives away from the conflict area, the ground traffic signal lamp array 10 is controlled to adjust from the traffic-restricted light signal to the warning traffic-passing light signal so as to indicate that the driving state of the entrance lane is adjusted from the traffic-restricted state to the warning traffic state.

Wherein the taxiways may be divided into conflict areas and non-conflict areas. The conflict area is an area which is close to an airport intersection and is easy to conflict with the ground service vehicle, and a taxiway section from a first reference line to a second reference line can be set as the conflict area, as shown in fig. 3. The first reference line and the second reference line are located on both sides of the airport intersection and may be symmetrically distributed. The positions of the first reference line and the second reference line can be adjusted adaptively according to actual requirements, such as the distance from the first reference line to the boundary line or the center position of the airport intersection is 50 meters, 60 meters, 80 meters, 100 meters or other values. At least one aircraft detector 20 may be disposed at the first reference line and the second reference line, respectively. Preferably, in order to reduce false detection and false detection rate as much as possible, three aircraft detectors 20 may be disposed at the first reference line and the second reference line, and the three aircraft detectors 20 are distributed in a triangular shape, as shown in fig. 5. When at least two aircraft detectors 20 of the three aircraft detectors 20 detect an aircraft, it can be determined that the aircraft passes through, otherwise, no aircraft passes through, so that false detection of the aircraft detectors can be reduced, and the condition that detection is missed due to failure of one aircraft detector 20 can be avoided. In addition, the direction of airplane taxiing can be acquired by adopting a plurality of airplane detectors arranged in front and at back. The airplane can enter the taxiway from the runway to the top and the bottom of the taxiway and taxis from the first reference line to the second reference line; the aircraft can also taxi from the second reference line to the first reference line and drive to the runway through the taxiway.

For example, when the aircraft detector 20 located at the first reference line detects that an aircraft is about to enter the collision area, feedback information may be sent to the signal controller 30, so that the signal controller 30 controls the traffic lights in the ground traffic light array 10 to emit the no-traffic light signal to prompt the ground service vehicle on the entrance lane to prohibit forward driving; when the aircraft detector 20 located at the second reference line detects that the aircraft has driven out of the collision area, feedback information may be sent to the signal controller 30 so that the signal controller 30 controls the traffic lights in the ground traffic light array 10 to adjust from emitting the no-traffic light signal to emitting the allow-traffic light signal or the warning-traffic light signal to resume the traffic of the ground service vehicles on the entrance lane.

Optionally, the signal controller 30 may be further specifically configured to obtain a flight schedule of the airport, determine whether the current flight is in the flight peak period according to the flight schedule, and if the current flight is determined to be in the flight peak period, control the ground traffic signal lamp array 10 to emit a traffic permission light signal when the aircraft detector 20 does not detect the aircraft, so as to indicate that the driving state of the entrance lane is a traffic permission state; if the situation that the vehicle is not in the peak flight period is determined, when the aircraft detector 20 does not detect the aircraft, the ground traffic signal lamp array 10 is controlled to send out a warning traffic light signal to indicate that the driving state of the entrance lane is a warning traffic state.

Because flights are also busy and idle in one day, generally, more flights are available in the daytime, fewer flights are available at night, and more flights are available, and the number of ground service vehicles is correspondingly increased. The ground traffic signal lamp array 10 can be controlled according to busy hours, specifically, when an airplane is not detected in busy hours, the ground traffic signal lamp array 10 can be controlled to send out a light signal allowing passage, so that the ground service vehicle can rapidly pass through an airport intersection, and the passage efficiency of the ground service vehicle is improved; when the plane is not detected in idle time, the ground traffic signal lamp array 10 can be controlled to send out a warning traffic light signal so as to warn the drivers of the ground service vehicles to selectively pass according to the actual situation of the airport intersection. It is understood that the above description is only one of the control manners, but not limited thereto, for example, the ground traffic signal lamp array 10 may be controlled to emit the warning traffic light signal to warn the driver of the ground service vehicle to selectively pass according to the actual situation of the airport intersection when the airplane is not detected in busy hours, and the ground traffic signal lamp array 10 may be controlled to emit the permission traffic light signal to allow the ground service vehicle to rapidly pass through the airport intersection when the airplane is not detected in idle hours.

Similarly, the signal controller 30 may be further specifically configured to control the ground traffic signal lamp array 10 to adjust from emitting the no-pass light signal to emitting the clear-pass light signal when the aircraft detector 20 detects that the aircraft leaves the collision area, if it is determined that the aircraft is currently in the flight peak, so as to indicate that the driving state of the entrance lane is adjusted from the no-pass state to the clear-pass state; or if the airplane detector 20 detects that the airplane leaves the conflict area when determining that the current airplane is not in the flight peak, controlling the ground traffic signal lamp array 10 to adjust from sending the traffic prohibition light signal to sending the warning traffic light signal so as to indicate that the traffic state of the entrance lane is adjusted from the traffic prohibition state to the warning traffic state.

the signal controller 30 may be specifically configured to receive and analyze a first control instruction sent by the remote control center 40 when the aircraft is detected as the detection result, and control the ground traffic signal lamp array 10 to send a traffic prohibition light signal according to the first control instruction, so as to indicate that the driving state of the entrance lane is a traffic prohibition state;

Specifically, the aircraft detector 20 may directly feed back the detection result to the signal controller 30, and the signal controller 30 automatically analyzes the detection result and controls the ground traffic signal lamp array 10 to emit a corresponding indication light signal according to the detection result; the aircraft detector 20 may also feed back the detection result to the remote control center 40, and the remote control center 40 issues a corresponding control instruction to the signal controller 30 according to the detection result, so that the signal controller 30 controls the ground traffic signal lamp array 10 to emit a corresponding indication light signal according to the received control instruction. The remote control center 40 may analyze the detection result, and automatically issue a corresponding control command to the signal controller 30 according to the analyzed detection result; the remote control center 40 may output the analyzed detection result to a background operator, and the background operator manually operates the remote control center 40, so that the remote control center 40 passively issues a control instruction to the signal controller 30 according to the input operation of the background operator, which is not limited herein.

Optionally, the remote control center 40 may be specifically configured to obtain a flight schedule of the airport, determine whether the current flight is in the peak of flight according to the flight schedule, and send a corresponding control instruction to the signal controller 30 according to the determination result and the feedback result sent by the aircraft detector.

As the number of airport flights increases, the density of ground service vehicles will also increase. As shown in fig. 5, in order to enable the service vehicles to queue up more orderly when the aircraft enters the conflict area, a second stop line may be defined behind the first stop line, and a plurality of traffic lights may be disposed in the area between the two stop lines and on both the two stop lines. And/or, in order to enable the ground service vehicle located behind to see the indicating light signal of the traffic light at the first time, at least one traffic light can be arranged on two sides of the first stop line.

In the embodiment of the present application, the ground traffic signal light arrays 10 may be distributed as shown in fig. 5, wherein, in the traffic signal lights disposed in the early warning area and the area between the first stop line and the second stop line, the intervals between any two adjacent traffic signal lights may be equal, partially equal, or different from each other. For example, the spacing between any two adjacent traffic signals may be 3 meters, 5 meters, 7.5 meters, 10 meters, or other values. For another example, the distance between two adjacent traffic lights gradually decreases along the driving direction of the entrance lane; alternatively, the distance between two adjacent traffic lights gradually increases in the driving direction of the entrance lane. Of course, the distance between two adjacent traffic lights may be varied randomly or in other manners, and does not necessarily exhibit the above-mentioned exemplary gradually decreasing or gradually increasing manner in a certain direction. In addition, when the traffic signal lamp is installed on the ground, the housing of the traffic signal lamp can be partially buried under the ground, so that the light-emitting indicating device protrudes out of the ground for the driver to watch; or the housing of the traffic signal may be attached to the road surface, without limitation. The light-emitting indicator of the traffic signal lamp may be the above-described lamp bead, and may also be other display structures, for example, the light-emitting indicator of the traffic signal lamp is a display screen, and may output indication information such as characters, patterns and/or animations on the display screen, which is not limited herein.

In practical applications, the traffic signal light with light emission can enable a driver to clearly see the indicating light signal at night, especially in bad weather (such as rain, fog and the like). In addition, because driver's vision is restricted when bad weather, when the lane route is unclear, the pilot light signal that each traffic signal lamp sent can also play the guide effect, reduces the risk that the driver left the lane.

In the embodiment of the present application, the housing of the traffic signal lamp may be rectangular, square, circular, polygonal, and the like. Signal controller 30 may also be referred to as a signal, a programmable switch, a traffic control signal, a traffic signal, an intersection traffic signal, or an intersection traffic control signal, among others. Specifically, the signal controller 30 transmits a control signal to the control signal input interface of the traffic signal lamp through the control signal output interface, and drives and controls the light emitting indicator to operate through the main control circuit board of the traffic signal lamp. One signal controller 30 may control the ground traffic light array on one entrance lane, or may simultaneously control the ground traffic light arrays on a plurality of entrance lanes; the ground traffic light array on an entry lane may be controlled by one or more signal controllers 30, but is not limited thereto. The signal controller 30 can be in communication connection with each traffic signal lamp in a wired and/or wireless manner; the aircraft detector 20 may also be communicatively coupled to the signal controller 30 by wire and/or wirelessly; the remote control center 40 may be connected to the aircraft detector 20 and the signal controller 30 in a wired and/or wireless manner, respectively.

In the embodiment of the application, when the traffic signal lamp sends the light signal allowing the vehicle to pass, the color of the light signal can be green or any single color or a combination of colors for indicating that the vehicle is allowed to pass; when the traffic signal lamp sends out the light signal for forbidding the vehicle to pass, the color of the light signal can be red or any single color or a combination of colors for indicating the forbidding the vehicle to pass; when the traffic signal lamp sends out the warning traffic light signal, the color of the light signal can be yellow or any single color or a combination of colors for indicating the warning traffic. When an aircraft is detected, all traffic lights in the ground traffic light array 10 may simultaneously emit a no-go light signal, such as a red light, in the form of a constant light or flashing. When no aircraft is detected, the traffic lights in the ground traffic light array 10 may issue a clear-to-go light signal or a warning-to-go light signal, which may be in the form of running lights, sequentially backward from the first traffic light closest to the airport intersection. The expression form of the light signal emitted by the traffic signal light is only an optional implementation form in the embodiment of the present application, and it may also be adaptively adjusted according to actual requirements, for example, the light signal for prohibiting passing may be emitted in the form of a running water light, and the light signal for allowing passing and the light signal for warning passing may be emitted in the form of a normally bright or blinking light, which is not limited herein.

Therefore, the ground traffic signal lamp array consisting of a plurality of traffic signal lamps is arranged on the ground of the early warning area of an entrance lane of the airport intersection in the embodiment of the application and is used for indicating the driving state of the entrance lane; when the aircraft detector arranged on the aircraft taxiway detects the aircraft, the signal controller can control the ground traffic signal lamp array to send out a traffic prohibition light signal so as to indicate that the driving state of the entrance lane is a traffic prohibition state, and at the moment, the ground service vehicle positioned on the entrance lane cannot drive into the early warning area and the airport intersection; when the aircraft detector does not detect the aircraft, the signal controller can control the ground traffic signal lamp array to send out a traffic-permitting light signal so as to indicate that the driving state of the entrance lane is the traffic-permitting state, at the moment, the ground service vehicle positioned on the entrance lane can drive into the early warning area and drive through an airport intersection, or when the aircraft detector does not detect the aircraft, the signal controller can control the ground traffic signal lamp array to send out a warning traffic-permitting light signal so as to indicate that the driving state of the entrance lane is the warning traffic state, and at the moment, the ground service vehicle positioned on the entrance lane can pass according to the current actual situation. It can be seen that, implement this application embodiment, can come intelligent management and control airport ground service car to pass at the airport intersection through ground traffic signal lamp's instruction to help reducing the probability that aircraft and ground service car take place the conflict.
