Problems solved by technology

Traditional tension sensors are mostly based on the principle of resistance strain gauges. The original signal needs to be amplified, analog-to-digital conversion and other links, which are easily disturbed by the environment, resulting in inaccurate data measurement.

Abstract

The invention discloses a small-sized unmanned aerial vehicle real-time tensile force detection apparatus and detection method, which belongs to the technical field of force measurement. The small-sized unmanned aerial vehicle real-time tensile force detection apparatus comprises an installation foundation support, an air cylinder, a motor and a paddle, wherein the installation foundation supportis fixed on a machine body and provided with a pressure sensor, an attitude sensor and the air cylinder; a piston is installed in the air cylinder, the shape of the piston is matched with the shape ofan inner wall of the air cylinder, the piston can slide relative to an air barrel, the air cylinder is also provided with an air valve and a vent hole, and when the air valve is opened, air can enterand exit the cylinder body freely. When the air valve is closed, the cylinder body and the piston form a sealing space. The vent hole is arranged on the bottom of the air cylinder and connected witha pressure sensor by virtue of an air pipe. The tensile force of the propeller is converted to the movement of the piston, and then the tensile force is indirectly measured in a pressure form in the air cylinder. By adopting the technical scheme, the real-time tensile force measuring structure is simplified; and by utilizing the shock absorption characteristic of the air cylinder, a measuring result is more accurate.

Description

technical field [0001] The invention relates to the technical field of force measurement, in particular to a real-time tension detection device and detection method for a small unmanned aerial vehicle. Background technique [0002] The air propeller is the main propulsion method of the UAV, and its efficiency under working conditions directly affects the efficiency of the UAV power system, thus affecting the endurance time of the UAV. [0003] The traditional propeller tension measuring device is to directly connect the motor and the propeller part with the load cell. Typical patents using this type of scheme include [CN201420711412-propeller motor tension testing device-utility model][CN201620555138-a kind of Ergonomics test platform]. The disadvantage of this type of solution is that system vibration will inevitably occur during the rotation of the propeller. Since the power part and the force measuring part are rigidly connected once, the high-frequency vibration is dir...
