Abstract

The invention discloses a checking system and checking method of an unmanned gyroplane PAPI (precision approach path indicator). The system comprises an unmanned gyroplane carrier and a ground station, wherein the unmanned gyroplane carrier comprises an unmanned gyroplane body and a flight controller, a positioning computer, a laser sensor, a GPS module, a data transmission module, a three-axis stability increasing cradle head, a forward-looking camera, a picture transmission module and a down-looking camera which are mounted on a fuselage; the ground station comprises a ground monitor station, a picture transmission base station and a data transmission base station. The checking system and the checking method have the following benefits: characteristics of high automation and autonomy are achieved, the approach process of a true unmanned aerial vehicle can be simulated, and a PAPI light can be detected; the expense is reduced, and the measuring accuracy is quite high; the requirements of various index tests of civil aviation airport PAPI light checking can be met, the traditional operating type namely flight checking can be replaced, a large amount of expense and labor consumption can be saved for the airport, the periodic requirement of PAPI light detection can be met, the accuracy of PAPI light indication is guaranteed, and the potential safety hazards of flight are reduced.

Description

technical field [0001] The invention belongs to the technical field of track indicators, in particular to a calibration system and a calibration method for a precision approach track indicator of a rotor unmanned aerial vehicle. Background technique [0002] The visual approach slope indicator system is a navigation aid lighting system that provides the correct glide path for aircraft approaching and landing; the precision approach path indicator is referred to as PAPI light, and its function is to determine the approach slope of the airport runway. Provide a correct approach course indication and four different deviation indications to the pilot performing the landing operation, provide the pilot with a visual judgment of the approach and landing angle, and provide a way for the pilot to finally correct the approach and landing attitude of the aircraft The reliable guarantee makes up for the landing safety hazard of the instrument landing system due to equipment failure.

Failure to follow the instructions of the PAPI light will cause potential safety hazards

[0003] At present, the verification of PAPI lights is carried out by using real aircraft and corresponding equipment for flight verification. The entire flight verification process is complicated and must be reported to relevant departments for approval, deploying aircraft and arranging flight verification crews, applying for routes, and formulating flight plans. , to implement a series of tasks such as flight inspection services and guarantees, and requires close cooperation between the flight inspection crew and ground personnel; although this method is relatively accurate and reliable for flight inspections, the entire inspection process is expensive. Time-consuming and labor-intensive, and PAPI lamps have periodic inspection requirements, so it is difficult to meet

At present, the existing approach course indicator test system simulates the approach course of the aircraft by physical means, uses a camera and an image acquisition card to transmit the image to the computer, and then manually judges whether the combination mode of the current PAPI light meets the requirements. The entire system It is very complicated and cumbersome, and the operation is complicated, requiring the cooperation of multiple people to complete the entire test task; and the degree of automation of the test system is very low, and because many devices need to be adjusted manually, the impact of human factors on the test accuracy is increased

[0004] Therefore, although the existing test system can test and adjust the PAPI lamp and save costs, its measurement accuracy is not high. Arrangement and adjustment are very inconvenient, which affects the efficiency and accuracy of calibration
