Description

Technical Field

[0001] The utility model relates to the field of airport runways, in particular to a variable indication marking device for airport runway release. Background Art

[0002] In recent years, runway intrusion incidents have occurred many times, and the problem of runway intrusion has received attention from the Civil Aviation Administration and major airports. With the in-depth promotion of the construction of "four-type airports" and "four-strong air traffic control", airport construction is rapidly developing in the direction of digitalization, networking, and intelligence. As one of the visual navigation lighting facilities to prevent runway intrusion, the airport runway release status variable indicator sign system has a direct impact on the safe operation of the airport due to its intelligence level.

[0003] The existing technologies include microwave detection, single-light monitoring, stop row lights, and runway release systems composed of navigation lights. There are certain defects. For example, its logic design is to manually remotely switch the stop row lights for release. The pilot uses the color of the navigation lights to determine whether the aircraft enters or exits the runway. The color of the lights changes according to the time countdown. At the same time, microwave detection is used to assist in determining whether the aircraft accidentally slips in. This design logic has several disadvantages: 1. In actual applications, the system is complex, with many equipment nodes, long communication distances, and large amounts of power carrier data, resulting in a high equipment failure rate. 2. The countdown time calculation changes the lights, which may cause the lights to change before the aircraft has slipped out. 3. The lamp window is small and the observation is not intuitive, especially in foggy weather or under strong sunlight during the day, when the color status of the lamp cannot be distinguished. Therefore, how to overcome the above-mentioned technical problems and defects has become a key issue that needs to be solved. Utility Model Content

The middle part of the bottom end of the closing plate 16 is hinged to the top of the vertical support rod 2.

[0030] In order to achieve the front and back swing of the top of the sign. Figure 4 , a driving mechanism 4 for controlling the front and rear swinging of the top of the sign 3 is arranged on the vertical support rod 2. The driving mechanism 4 comprises a control panel 41 fixedly arranged on the back of the sign 3, a control rod 42 extending downward is vertically fixedly arranged in the middle position of the back of the control panel 41, a slide groove 43 arranged along the length direction of the control rod 42 is provided at the bottom front end of the control rod 42, and an electric push rod 44 is fixedly arranged at the top rear end of the vertical support rod 2, and a slider 45 that can slide in the slide groove 43 is hingedly arranged at the telescopic end of the electric push rod 44. The electric push rod 44 is operated by remote control to extend or contract, so that the top of the sign 3 is swung back and forth through the control rod 42. In this process, the slider 45 slides in the slide groove 43.

[0031] The method of using the variable indicator marking device for runway release at an airport of the utility model is as follows: first, when assembling the device, fix the mounting plate 17 to the closing plate 16, and then fix the wireless communication module 5 and the sensor module 6 to the mounting plate 17, so as to facilitate subsequent assembly. Place the servo motor 9 and the bearing 11 between the fixing ring 8 and the rotating cylinder 10, and sleeve the rotating cylinder 10 on the fixing ring 8, and use bolts to limit the upper and lower heights, and at the same time connect the spline at the output end of the servo motor 9 to the rotating cylinder 10. Hinge the closing plate 16 with the vertical support rod 2, and then fix the clamping plate 15 to the bottom end of the light board 13, and place the light board 13 from below the sign board 3 into the display port 12 of the sign board 3, at which time the clamping plate 15 abuts against the sign board 3. Insert the closing plate 16 into the sign 3 from the bottom of the sign 3 and fix it with bolts.

Finally, install the electric push rod 44 on the vertical pillar, and the slider 45 is placed in the slide groove 43 and its tail end is hinged with the output end of the electric push rod 44. The device is fixed at a suitable position on the side of the runway. When the device is fixed, the clarity of the driver's observation can be increased due to the large and eye-catching sign surface, so the device nodes can be reduced. At the same time, the sign surface information is variable, and multi-system interaction can be remotely performed, which is convenient for instructing the driver's actions.

[0032] When in use, the position of the aircraft is detected by the microwave detector 7, and remote interaction is performed through the sensor module 6 and the wireless communication module 5, thereby controlling the servo motor 9 and the electric push rod 44 to work, so that the rotating cylinder 10 and the fixed ring 8 rotate relative to each other, and at the same time, the electric push rod 44 pushes or pulls the control rod 42 to swing, so that the top of the sign 3 swings back and forth. Make the light board 13 always face the direction of the aircraft, which is convenient for the driver to observe the instructions of the sign 3. At the same time, the color-changing light 14 can be controlled to work according to the moving state and position of the aircraft to attract the driver's sight, avoid the driver's distraction, and reduce the probability of accidental slip and intrusion on the runway. In this process, heat is dissipated through the space at the sealing net, and dust is treated through the sealing net.

[0033] Embodiment 2: The same points as Embodiment 1 are not described in detail, and the difference is that:
