No-manned machine distant control chain circuit interruption judging and processing method

Abstract

The invention provides a method for determining and processing an interruption of a remote control link for an unmanned aerial vehicle, which is applied to the flight control and management of an autonomous control type unmanned aerial vehicle. The method comprises the following four steps of a determination of the link interruption, a waiting process of the link interruption, an irreducible process of the link interruption and a recovery process of the link interruption. The method sufficiently uses the prior information to achieve the monitoring to the remote control data link; uses interconversions among the four link states and corresponding treatment measures to achieve the self-independent monitoring and management for the link state of the unmanned aerial vehicle; and uses a corresponding treatment measure according to a specific state of the unmanned aerial vehicle to effectively improve flight security and reduce risks under the circumstance that the unmanned aerial vehicle loses a ground control. The invention has an important engineering application value.

Description

technical field [0001] The invention relates to a method for judging and processing the interruption of a remote control link of an unmanned aerial vehicle, belonging to the field of automatic control of unmanned aerial vehicles. Background technique [0002] According to the functions, the UAV system is mainly composed of four parts: aircraft system, radio measurement and control system, mission equipment system, and comprehensive support system. The radio measurement and control system of the UAV is usually the UAV data link system; it can be divided into uplink and downlink according to the direction of data transmission. The uplink mainly completes the sending and receiving of remote control commands from the ground station to the UAV, which is generally called the remote control link; the downlink mainly completes the sending and receiving of telemetry data, infrared or TV images from the UAV to the ground terminal As well as the transmission of tracking and positionin...

Problems solved by technology

[0003] From another perspective, the data link inevitably has reliability problems. If the telemetry link is interrupted, the ground personnel cannot know the status of the aircraft in real time, but the aircraft does not know that the telemetry link is interrupted, so there is nothing to do; The remote control link is interrupted, that is, the remote control command cannot be sent to the aircraft. At this time, the aircraft can know that the remote control link has been interrupted according to the received remote control data frame

Therefore, for the interruption of the remote control link, some appropriate protective and remedial measures can be taken from the perspective of flight control and management; although it is a subordinate and passive method, it is also an effective way to improve flight safety And method, is the last barrier to deal with data link interruption failure
