Method for improving integrity of flight verification data of unmanned aerial vehicle

Abstract

The invention belongs to the technical field of flight verification, and provides a method for improving the integrity of flight verification data of an unmanned aerial vehicle, and the method comprises the steps: temporarily storing the flight verification data through a cache module of airborne verification equipment, monitoring whether ground verification equipment sends a request data instruction or not in real time, and carrying out the verification of the flight verification data according to instruction parameters; and the requested verification data is retransmitted to the ground verification equipment, and the ground verification equipment judges whether the verification data which is not received due to the influence of the data link exists or not through a checking module and a compensation module according to the UTC time parameter values in the two groups of newly received verification data. The problems that the verification data is incomplete and the signal quality of the ground navigation equipment cannot be truly reflected due to the fact that the unmanned aerial vehicle data link is interfered and cannot normally transmit the verification data are solved, the data integrity of unmanned aerial vehicle flight verification is improved, and thus the accuracy of flight verification is improved.

Description

technical field [0001] The invention relates to the technical field of flight verification, in particular to a method for improving the integrity of UAV flight verification data. Background technique [0002] It is more difficult to carry out oil exploration and development in mountains, deserts, alpine and other sparsely populated areas with inconvenient transportation, and consumes more human, financial and material resources. The use of helicopters or small fixed-wing aircraft for oil exploration and development can save a lot of resources. At present, the use of helicopters or small fixed-wing aircraft for oil exploration and development has entered a stage of rapid development with promising development prospects. However, in these areas, the natural conditions are relatively harsh. In order to ensure that the aircraft can cruise normally or land safely, it is necessary to ensure that the navigation signals emitted by the ground navigation equipment can guide the aircra...

Problems solved by technology

[0007] This invention solves the problem that the UAV data link is interrupted due to environmental interference, so that the calibration data received by the ground calibration equipment is incomplete and cannot truly reflect the quality of the signal transmitted by the ground navigation equipment, which leads to the comparison of flight calibration accuracy. low problem
