Abstract

The invention relates to the field of UAV control and monitoring, particularly a UAV flight control method and device having the automatic correlation monitoring function. The GPS second pulse is taken as the reference to randomly generate the vibration time; the radiofrequency signal transmitted by a satellite is processed into a GPS message in an NEMA0183 format, and the GPS message is stored in an ADS-B broadcasting array after being parsed and packaged; and meanwhile, the speed information of the UAV acquired by an airspeedometer and the ID message of the UAV can be stored in the ADS-B broadcasting array at the same time; the trigger signal is generated according to whether the L wave band antenna is occupied by the L wave band data transmission radio station and the vibration time, the radio frequency switch can be switched according to the trigger signal, so that a 1090 emitter or the L wave band data transmission radio station is connected with the L wave band antenna via the radio frequency switch, and the UAV automatic correlation monitoring function can be completed on the premise of guaranteeing the UAV flight control function.

Description

technical field [0001] The invention relates to the field of UAV control and monitoring, in particular to a UAV flight control method and device with automatic correlation monitoring function. Background technique [0002] UAVs have broad application prospects in military strikes, military reconnaissance, aerial photography, telemetry and remote sensing, resource exploration, pesticide spraying and other fields. The flight control system is the core part of the UAV. At present, the AP50 flight control system developed by UAV FlightSystems in the United States has two main functions: flight stabilization control and navigation mission control. The world's smallest autopilot MP2028 produced by Micropilot , has the advantages of small size and low power consumption. The iFLY40 flight control system developed by Beijing University of Aeronautics and Astronautics integrates a three-axis MEMS gyroscope and a three-axis MEMS accelerometer, and uses a strapdown navigation algorithm...
