Abstract

The embodiment of the invention provides an unmanned aerial vehicle shielding cable grounding point determination method and device, a cable and an unmanned aerial vehicle. The method comprises: obtaining the working wavelength corresponding to each airborne device in the unmanned aerial vehicle; and determining a grounding unit length based on the obtained shortest working wavelength in the working wavelengths, determining a grounding interval point of the shielding cable by taking the joint of the shielding cable and each airborne device as a starting point and taking a length smaller than or equal to the grounding unit length as an interval, and determining a point where the grounding interval point is connected with the reference ground as a grounding point. The embodiment of the invention can improve the electromagnetic compatibility of the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method, a device, a cable and an unmanned aerial vehicle for determining the grounding point of a shielded cable of an unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "UAV", does not need to be driven by humans, and can perform tasks in dangerous environments. It is widely used in aerial reconnaissance, surveillance, and communication tasks. [0003] The drone uses its drone infrastructure as a reference ground, which is the reference point of the drone's line voltage. The drone infrastructure refers to the structural skeleton of the drone and the metal skin riveted or welded on the structural skeleton. , corner pieces, brackets and profiles, etc. Each device is installed on the infrastructure of the UAV according to the location diagram of the device, and its power supply is connected to the infrastructure of the UAV, ...
