Embodiment 1

[0040] combine figure 1 As shown, a high-precision aircraft guidance and landing system is disclosed in Embodiment 1, including an aircraft, a landing platform and a central control system.

[0041] The landing platform includes 5 annular parking areas and a central landing area, the annular parking area and the central landing area are concentrically arranged, the width of the annular parking area in the landing platform is equal, and the light reflection intensity of the surface of the landing platform The area increases successively from the outer circular parking area to the central landing area.

[0042] The aircraft includes a body, the bottom of the body is provided with a photoelectric sensor for detecting the intensity of reflected light from the landing platform, and the distance between the photoelectric sensor and the center of the body is set, and the photoelectric sensor rotates 360° around the center of the body; this implementation The aircraft described in th...

Embodiment 2

[0066] Based on the guidance method and guidance system in Example 1, Example 2 has been further improved. Since the aircraft cannot be accurately maintained at a certain position when using a photoelectric sensor to detect the landing platform, a slight shake will occur during the flight, so , a high-precision aircraft guidance and landing system is further proposed in this embodiment 2, combined with figure 2 As shown, the system also includes aircraft, landing platform and central control system.

[0067] Specifically, the landing platform includes two ring-shaped parking areas, a transitional parking area, three Bluetooth beacons, and a central landing area. The circular parking area, the transitional parking area, and the central landing area are arranged concentrically. The area is located between the ring-shaped parking area and the central landing area. The width of the ring-shaped parking area in the landing platform is equal, and the reflection intensity of the opti...

Abstract

The invention relates to a high-precision aircraft guided landing system and method. The system comprises an aircraft and a landing platform, a photoelectric sensor in the aircraft issues a detection light beam, and meanwhile, optical signals reflected by a landing platform are received. Due to the fact that the intensities of signals reflected from outside to inside on the landing platform are different, according to the optical signals detected by the photoelectric sensor, the area where the aircraft is located can be accurately judged, and the direction of the aircraft can be corrected by recording the duration time of the optical signals with different intensities, so that it is ensured that the aircraft accurately lands to the center landing area of the platform, and the problem that in the prior art, the aircraft landing positioning precision is poor is solved.

Description

technical field [0001] The invention belongs to the technical field of aircraft, and relates to a system and method for guiding and landing a high-precision aircraft. Background technique [0002] With the rapid development of the aircraft and logistics industry, strong market demand has promoted the development of "aircraft + logistics", and made aircraft logistics a new hot field. In terms of aircraft logistics, how to achieve precise landing is a key issue. The accuracy of landing is directly related to the normal operation of the subsequent logistics system. The conventional landing method is to use GPS to analyze the position and compare it with the predetermined position, so as to realize the landing to the pointed position, but this method is affected by the accuracy of the GPS system. For civilian GPS satellite signals, the position accuracy can generally be resolved to within ten meters level, but for the landing accuracy that needs to be accurate to the centimeter...
