Description

Airport runway warning system

technical field

The invention relates to a warning system for aviation safety, especially an "airport runway warning system" which can provide real-time conditions of the runway when an aircraft takes off and lands.

Background technique

Aviation safety can be roughly divided into two main parts: the aviation safety when the aircraft is flying in the air and the ground safety when the aircraft takes off and landing. Among them, air safety causes huge casualties due to accidents, and it has become the responsibility of the supervision of various countries today. Government agencies and aircraft manufacturers are competing to invest a lot of manpower and material resources in research and development of advanced electronic auxiliary equipment, which has greatly improved air safety, such as: radar control, automatic navigation, satellite positioning, collision avoidance systems, etc.

However, when an aircraft takes off and lands, a large amount of manpower control and manpower instruction information will be involved. Therefore, when the air traffic controller or the pilot of the plane is negligent, mentally lax, and inattentive, it is easy to enter the wrong runway, misjudge information, Obstacles on the runway are not noticed, visual control is not possible due to poor vision, communication information is misunderstood due to poor communication, real-time information cannot be obtained due to communication interruption, etc. These problems have become the dead ends of ground safety in aviation safety.

In view of this, the inventor conducted research on the issue of ground safety, and then created the present invention "Airport Runway Warning System", in order to add the necessary warning system to provide real-time information on the runway to air traffic control under the original security framework. Personnel and aircraft are driven to eliminate dead spots for ground safety.

Contents of the invention

The purpose of the present invention is to provide an airport runway warning system, which provides real-time information on the runway to air traffic control personnel and aircraft drivers, so as to eliminate hidden dangers of ground safety.

The airport runway warning system of the present invention is to arrange a plurality of warning lights parallel to the runway on both sides of the runway (Runway), and each warning light is connected with a sensor for sensing whether its adjacent runway area is clear, and all All warning lamps and sensors are connected to a central control unit installed on the airport tower, and the central control unit is further connected with a main display lamp installed at the entrance of each connecting road and capable of switching between red and green light sources. When a sensor senses an obstacle on the runway, it can make its corresponding warning lights and all the main display lights display a red light source to warn that the runway is not clear.

Each of the above-mentioned warning lamps is respectively provided with a light-emitting part relative to the direction of both ends of the runway. The light-emitting part can switch between red light source and green light source, and can control the landing direction to be green light source, and the non-landing direction to be red light source. During implementation, the light-emitting part includes multiple red light-emitting diodes and multiple green light-emitting diodes to adjust the intensity of the light according to the difference in visibility caused by the weather; moreover, the sensor can also be set on the warning lamp to facilitate manufacturing and installation .

The airport runway warning system that the present invention is made up of above-mentioned assembly comprises following main control method:

When all sensors detect that the adjacent runway area is clear of obstacles and after a preset period of time, all warning lamps and main display lamps will display green light.

When any sensor detects that there is an obstacle in the adjacent runway area, the warning lamp connected to the sensor will display a red light source, and make all the main display lights display a red light source, and send an obstacle signal to the central control unit, and It is also possible to make other warning lamps that have detected obstacles earlier and display red light sources continue to display red light sources.

When the tower allows the aircraft to take off and land, through the central control unit, all the main display lights will generate green light sources, and the light emitting part of each warning light relative to the starting end of the aircraft's take-off and landing will also generate green light sources, so that the ground aircraft can It is known that the runway is clear; at this time, the light-emitting part on the other side of each warning lamp is a red light source, so as to prevent the aircraft taking off and landing from entering the runway in the opposite direction.

If the above-mentioned situation is to allow the aircraft to take off, the sensor senses that the aircraft enters the runway, then the corresponding warning lights and all the main display lights are converted from green light sources to red light sources to prevent other aircraft from entering or passing the runway.

And if the situation is to allow the aircraft to land, all warning lights and main display lights on the runway should be green light sources. However, during implementation, in order to ensure that the runway is clear and to prevent the aircraft waiting to take off from the taxiway from entering the runway without instructions, the central control unit can further set up a first control interface next to the ground control seat. The control interface can switch the main display light to a red light source, so that the aircraft preparing to take off can wait outside the runway for approach.

According to this, when the aircraft takes off and lands, the warning lamps with green light sources on both sides of the runway can be switched to red light sources in sequence according to the passing position of the aircraft. The warning lamps on the side and the main display lamps can once again present green light sources.

In addition, if the ground stand-by pilot indicates permission to take off from the tower, but the main display light or any warning light shows a red light source, it means that there may be obstacles on the runway. At this time, the stand-by pilot can reconfirm with the tower control personnel The state of the runway to avoid obstacles such as small animals suddenly entering the runway and hindering takeoff.

During the implementation of the present invention, a disengagement sensor can be further arranged at the entrance of each connecting road between the airport runway and the taxiway, and the disengaging sensor is connected with the central control unit. When the runway enters the taxiway and completely leaves the runway, the departure sensor can release a departure signal to the central control unit, so that each warning light and the main display light can be switched to green light sources.

In order to enable tower personnel to understand and control the state of the runway more clearly, the central control unit can further set up a second control interface next to the approach control seat of the tower in addition to the aforementioned first control interface next to the ground control seat. Management and control interface, the first and second management and control interfaces are connected with the central control unit and displayed synchronously with each warning light and main display light, and all belong to the manual control device (override device) that can temporarily replace the automatic control, so as to strengthen the warning effect.

Furthermore, in order to strengthen the warning, when the above-mentioned warning lamps emit red light sources, intermittent lighting can be used to produce a flickering effect, so that the warning effect can be more significant.

Compared with the prior art, the present invention can provide the driver and tower personnel with one more piece of information on the current situation of the runway, and can also provide real-time warnings for obstacles that suddenly appear on the runway, and can also remind other people waiting to take off and land. Whether there are aircraft taking off and landing on the airstrip.

Detailed ways

According to the technical means of the present invention, the modes suitable for the implementation of the present invention are listed below, and are described as follows in conjunction with the drawings:

As shown in Fig. 1 and Fig. 2, it is a schematic plan view of the preferred embodiment of the present invention and a schematic view of the warning lamp of the preferred embodiment of the present invention. The figure reveals that the airport runway warning system of the present invention is to arrange a plurality of warning lamps 10 parallel to the runway on both sides of the runway of the airport. On the road shoulder, during implementation, it can also be arranged at the interval of every two runway lights 20 .

As shown in Fig. 3 and Fig. 4, each warning lamp 10 is respectively provided with a light emitting part 11 relative to the direction of both ends of the runway, and the light emitting part 11 can switch between a red light source and a green light source, for example:

The light emitting part includes a plurality of red light emitting diodes and a plurality of green light emitting diodes, so as to switch between the red light source and the green light source. During implementation, the light-emitting part 11 composed of multiple red LEDs and multiple green LEDs can also adjust the intensity of its light according to the difference in visibility caused by weather, so as to enhance its recognition.

Each warning lamp 10 is connected with at least one sensor 30 for sensing whether the adjacent runway area is clear. In this embodiment, the sensor 30 is directly arranged on the warning lamp 10. In actual implementation, the sensor 30 can also be arranged on the runway. For other parts in the area, the sensor 30 can be implemented by adopting infrared sensing technology or other wireless sensing technology, so as to sense the ground area of the runway and the appropriate height of the ground area.

In addition, during implementation, blocking or other means of transmitting and receiving signals can also be used between every two adjacent sensors 30 to detect whether there are obstacles such as vehicles or animals passing between every two adjacent sensors 30, In order to be able to reliably detect any obstacles that may appear on the runway.

As shown in Fig. 1 and Fig. 5, all warning lamps 10 and sensors 30 are all connected to a central control unit 40, and this central control unit 40 should be located in the tower 50, for the control personnel in the tower 50 to know the runway at any time state.

Secondly, at least one main display light 60 is set at the entrance of each connecting road between the airport runway (Runway) and the taxiway (Taxiway), and the main display light 60 is connected with the central control unit 40 and can perform red and green light To switch, a disengagement sensor 70 is arranged at the entrance of each connecting road between the airport runway and the taxiway.

The method of cooperation and control of the aforementioned warning lamps 10, each sensor 30, central control unit 40, main display lamp 60, and disengagement sensor 70 is as follows:

When all the sensors 30 detect that there is no obstacle in the adjacent runway area and after a preset period of time, all the warning lamps 10 and the main indicator lights 60 will display green light sources to indicate that the runway is clear.

When any sensor 30 detects that there is an obstacle in the vicinity of the runway area, the warning light 10 connected to the sensor 30 and all the main display lamps 60 promptly display a red light source, and an obstacle signal is released to the central control unit 40, and at the same time It is also possible to make other warning lamps 10 that have detected obstacles earlier and display red light sources continue to display red light sources to warn of obstacles on the runway.

When the tower 50 allows the aircraft to take off and land, the central control unit 40 makes all the main display lamps 60 and the light emitting parts 11 on the warning lamps 10 relative to the starting end of the aircraft take off and land produce green light sources, and each warning lamp 10 is relatively The other side of the light emitting part 11 of the green light source then presents a red light source to prevent the aircraft taking off from taxiing in the opposite direction.

Therefore, when the aircraft takes off and lands, the two sides of the runway present green light sources through the warning lamps 10, and switch to the red light source in sequence according to the passing position of the aircraft. After the aircraft completely leaves the runway and passes through the preset time, The warning lights 10 and the main display lights 60 on both sides of the runway can present green light sources again.

When the aircraft is allowed to take off, when the sensor 30 of any warning lamp 10 senses an obstacle (when the aircraft allowed to take off enters the runway or when any obstacle enters the runway), all the main display lamps 60 are made to emit a red light source. It is used to warn the driver that the runway may not be clear yet.

For example: if the pilot on standby on the ground indicates permission to take off at the tower, and when the main display light 60 or any warning lamp 10 shows a red light source, it means that there may be obstacles on the runway, and the pilot on standby at this time can communicate with the control personnel of the tower Confirm the runway status again to avoid obstacles such as small animals suddenly entering the runway and hindering takeoff.

And when the aircraft lands on the runway and enters the taxiway from any connecting road and completely leaves the runway, the departure sensor 70 can release a departure signal to the central control unit 40, so that each warning lamp and the main display lamp can be switched. into a green light source.

In order to enable the tower 50 personnel to understand the state of the runway more clearly, a first control interface 91 can be further set beside the ground control seat of the tower 50, and a second control interface 92 can be set beside the approach control seat. 1. The second control interface is connected with the central control unit 40 and displayed synchronously with each warning lamp 10 and the main display lamp 60, and all belong to the manual control device (override device) that can temporarily replace the automatic control, so that the warning and control can be strengthened .

For example: in the state where the aforementioned tower 50 allows the aircraft to take off and land, all the main display lights 60 and the light-emitting parts 11 at the starting end of the warning lights 10 relative to the aircraft take-off and landing should produce green light sources; but in order to ensure that the runway is clear, and To prevent the aircraft waiting to take off on the taxiway from entering the runway without instructions, the first control interface 91 of the central control unit 40 can switch the main display light 60 to a red light source, so that the pilot on the ground can easily distinguish Exiting the runway is in a state of no entry, and then the aircraft preparing to take off is allowed to wait outside the runway for approaching, so as to achieve the above-mentioned purpose of preventing unintentional entry into the runway.

As shown in Figure 6, at the moment before the aircraft lands, if an obstacle (for example: an engineering vehicle or other obstacles) suddenly breaks into the runway, the relevant control personnel of the tower 50 have no time to find that there is an obstacle or cannot detect the obstacle. When notifying the pilot of the aircraft urgently, through the airport runway warning system, the pilot can detect the abnormal situation on the runway at the first time, and even directly display the location of the abnormal situation with a red light source , so that the pilot of the aircraft can pull up the aircraft in real time to avoid collisions, and it can also allow the relevant staff on the ground to find and eliminate obstacles in the shortest time.

Accordingly, the present invention can provide one more piece of information on the current status of the runway to the pilot and tower personnel, and can also provide real-time warnings for obstacles that suddenly appear on the runway, and can also remind other aircraft waiting to take off and land on the runway whether There are planes taking off and landing.

However, the above descriptions and drawings are preferred embodiments of the present invention, and are not intended to limit the present invention; for example, when the aforementioned warning lamps emit red light sources, they can generate flashing effects by intermittently emitting light. In order to make the warning effect more obvious. Therefore, all those that are similar or identical to the structure, device, and features of the present invention should fall within the creation purpose of the present invention and the scope of the patent application.
