Design And Implementation Of Ground Control Software For Rotor Aircraft

Rotor aircraft is an aircraft with rotors in the structure of the aircraft,and lift is obtained by rotator rotation,including rotors and helicopters.Rotor aircraft is widely used in medical treatment,rescue,detection,public security law enforcement,scientific research,military and other fields,such as search and rescue in mountainous forest areas,military fire fighting and so on.However,because the operating space of rotorcraft is usually low-altitude and ultra-low-altitude,which is greatly affected by topographic fluctuation and friction layer(1-2 km from the ground to the air in the troposphere),how to control its arrival in the mission area on time and safely and effectively avoid the dangers of terrain,meteorology and attack becomes an urgent problem to be solved.After analyzing the existing software for the control of rotorcraft aircraft,it is found that most of the existing software uses ground controllers to judge the flight situation of rotorcraft aircraft manually and edit control instructions manually.Human-computer interaction is frequent,manual operation is too much,and the degree of automation is low,which results in the high work intensity of ground controllers and the difficulty of meeting the accuracy and timeliness of the control of rotorcraft aircraft.Requirement.With the development of airborne sensors,air-to-ground communications,geographic navigation,radar and other communication and detection technologies,ground controllers can receive flight parameters information(including longitude,latitude,altitude,speed,pitch,etc.)of rotorcraft aircraft by active and passive means,access real-time meteorological information,load large-scale digital maps of mission area,and acquire them comprehensively,automatically and in real time.Rotor aircraft itself and mission area environment information.Through real-time analysis of geographic,meteorological and regional environment,the mission performance of the Rotor aircraft is monitored,the threat situation is warned,the flight situation is calculated and controlled,the mission objectives are dynamically allocated and the flight control of the Rotor aircraft is carried out to ensure the smooth completion of the mission.This paper extracts the typical process of the rotorcraft aircraft to carry out the requirement analysis,and designs it with the main line of sailing,flying to the designated area,dynamic assignment of mission objectives,flight control,mission completion and return.It clarifies the capability needed to be realized in each stage,and designs the function,processing flow and the structure of database tables and realizes the software.In the process of software design,the application process of typical tasks is summarized,and the key technologies aiming at route planning,dynamic assignment of mission objectives,accurate terminal control and other functions are proposed and solved.The existing control software can not automatically solve the problem of generating flight data and control instructions according to operational tasks,environment and flight parameters.The real-time control of rotorcraft aircraft is realized.Accurate control.The functions and interfaces of the software are checked and verified.The software is tested through data access and flight guidance to check whether it meets the design expectations.Through testing,the design or coding errors are found,and the software is improved.The ground control software of the rotorcraft is designed and implemented,which greatly improves the flight safety of the aircraft through intelligent analysis,and the automated processing greatly reduces the work intensity of the ground control personnel.Through software design,implementation and verification,a stable,reliable and easily expandable ground control software for rotorcraft is provided for users.The software can be directly applied to the control projects of UAV,helicopter and other rotorcraft aircraft.Only by adding the interface adapter,the software functions required by the project can be realized quickly,which not only shortens the development cycle of the whole software,but also shortens the development cycle of the whole project and saves human resources.Material resources,reduce the cost of development.
