Logistics unmanned aerial vehicle carrying UWB positioning tag

Abstract

The logistics unmanned aerial vehicle carrying the UWB positioning label comprises a cylindrical bottom shell, and is characterized in that a crank connecting rod mechanism is arranged in the cylindrical bottom shell and connected with external torque, and the top end of the crank connecting rod mechanism is movably connected with a sliding piston through a hinge; the sliding piston is slidably connected with the inner wall of the cylindrical bottom shell through a contact surface, the side wall of the sliding piston is correspondingly connected with a side supporting rod through a hinge, the top end of the side supporting rod is connected with an assembled machine shell through a hinge, and L-shaped supporting pipes are uniformly and fixedly installed on the side wall of the cylindrical bottom shell through welding; and a lubricant slope extrusion shell is fixedly mounted at the top end of the L-shaped supporting pipe through a bolt, the lubricant slope extrusion shell is filled with a lubricant, the lubricant slope extrusion shell and the L-shaped supporting pipe are communicated with each other, and the device solves the problem of poor practicability at present.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a logistics unmanned aerial vehicle equipped with UWB positioning tags. Background technique [0002] At present, the positioning and navigation of motion carriers such as drones basically rely on GPS and inertial navigation systems. Outdoor GPS positioning is not accurate enough due to the limitations of terrain, man-made buildings, weather and other factors, and it is difficult to meet indoor and centimeter-level positioning requirements. Sensor positioning is also easily interfered by the external environment, and the positioning accuracy is low and the range is small. At present, when the UWB technology is used in the market to realize cross-regional positioning and navigation, in different UWB signal coverage areas, the activity label needs to be replaced, which brings inconvenience to logistics and transportation. To sum up, across the indoor a...

AI Technical Summary

Problems solved by technology

[0002] At present, the positioning and navigation of moving carriers such as drones basically rely on GPS and inertial navigation systems. Due to the limitations of terrain, man-made buildings, weather and other factors, outdoor GPS positioning has insufficient accuracy, and it is difficult to meet indoor and centimeter-level positioning requirements.

Sensor positioning is also easily disturbed by the external environment, and the positioning accuracy is low and the range is small

At present, when using UWB technology on the market to realize cross-regional positioning and navigation, in different UWB signal coverage areas, it is necessary to replace the active label, which brings inconvenience to logistics and transportation.
