Mooring cable traction force vector measuring mechanism of mooring unmanned aerial vehicle

Abstract

The invention provides a mooring cable traction force vector measuring mechanism of a mooring unmanned aerial vehicle. The mooring cable traction force vector measuring mechanism of the mooring unmanned aerial vehicle can measure and feed back mooring cable traction force vector information in real time, so that a flight control system can effectively regulate and control the unmanned aerial vehicle to keep a normal flight attitude at any time and ensure the flight safety of the mooring unmanned aerial vehicle. The vector measuring mechanism comprises a self-adaptive follow-up mooring cable connecting mechanism and a sensor group; the self-adaptive follow-up mooring cable connecting mechanism comprises two semicircular pull rings and a sliding buckle connecting assembly; the sensor group comprises angle sensors used for measuring the rotating angles of the two semicircular pull rings respectively and a tension sensor arranged between a mooring cable and a mooring unmanned aerial vehicle connecting point; the direction indicated by the combination of the rotation corners of the two semicircular pull rings is a traction force vector direction; and the tension measured by the tensionsensor is a traction force vector. Reliable basis and effect feedback are provided for the implementation of effective regulation and control of the mooring unmanned aerial vehicle by the flight control system, and flight safety is guaranteed.

Description

technical field [0001] The invention relates to a tension measuring mechanism, in particular to a tethered unmanned aerial vehicle mooring cable traction tension vector measuring mechanism, which belongs to the field of tethered unmanned aerial vehicle flight control. Background technique [0002] At present, in the field of tethered UAV flight control, due to the effect of tethered traction, there is no effective monitoring method for an important flight parameter, namely: the measurement of the traction force vector (including the magnitude and direction of the traction force), this parameter With the change of flight status such as wind force, wind direction, mooring cable length (weight), flight altitude, etc., especially when the wind force and wind direction change suddenly, the UAV is often out of control due to the lack of effective monitoring and control means. Seriously affect the use function of the mount and the wind resistance of the UAV, and even lead to a cras...
