Low-altitude aircraft safety management system and method

Abstract

The invention discloses a low-altitude aircraft safety management system. The system includes a global positioning decoding module, a flight control unit, an inertial navigation assembly, an extendedKalman filter and a steering gear controller, wherein the inertial navigation assembly is connected with the extended Kalman filter, the steering gear controller is connected with the extended Kalmanfilter, and the flight control unit is connected with the global positioning decoding module and the extended Kalman filter respectively and is used for receiving the real-time position information and the real-time speed information of an aircraft to determine whether the aircraft is located within the preset authorized airspace and starting a control plan if the aircraft is not located within the preset authorized airspace. The invention further discloses a method. The method comprises steps that S01, the real-time location information and the real-time speed information of the aircraft areobtained; and S02, the real-time location information and the real-time speed information are compared with preset authorized airspace data, if the aircraft is not located within the preset authorizedairspace, the control plan is initiated. The system and method have advantages of low cost, high reliability, and the like.

Description

technical field [0001] The invention mainly relates to the field of aircraft technology, in particular to a low-altitude aircraft safety control system and method. Background technique [0002] The control of low-altitude aircraft is a strategic issue related to national security. Such as figure 1 As shown, the principle of the flight control of the aircraft is as follows: the positioning and navigation system of the aircraft is the central nerve of the flight control of the aircraft, and plays a very critical supporting role in the flight process of the aircraft. The global positioning information provided by the global positioning and navigation constellation (GPS / BD / Glonass / Galileo) is parsed by the global positioning decoding module 1 to give real-time position and speed information, and together with the real-time data of the inertial navigation component 3 onboard the aircraft, the Kalman The filter 4 obtains real-time navigation information such as accurate aircraft...

AI Technical Summary

Problems solved by technology

With the rapid development of UAV technology, related industries and personal consumption have higher and higher requirements for the application of aircraft. Incidents where aircraft pose potential security threats to civil aviation, electric power, and important national defense targets occur from time to time

Strengthening the management of low-altitude aircraft has become a major security issue that must be resolved urgently. Due to the low, small, and slow characteristics of drones, it is neither realistic nor economical to deploy large-scale reconnaissance and countermeasure systems across the country.
