First, gravity and vertical direction pulling force (lifting force of the airplane) detection principle.
Utilize sensor I2 to fix the unmanned aerial vehicle on support 1 and measure, control box 9 sends the data signal who gathers sensor I2 to outside computer system, reachs gravity through the operation.
One end of the sensor I2 is connected with the external bracket; the other end is connected with support 1, and rethread mount pad 6 is connected with unmanned aerial vehicle, installs back on this check out test set when unmanned aerial vehicle, can carry out gravity or vertical direction pulling force measurement.
It should be noted that, during gravity measurement: the power that sensor I2 bore includes this check out test set dead weight and unmanned aerial vehicle weight, consequently need carry out "zero clearing" earlier and handle, after detaching the weight of equipment self, carries out the measuring of weight with fixed to the equipment of unmanned aerial vehicle again, guarantees the measuring accuracy.
Vertical direction tension (lift of the aircraft) measurement: when detecting unmanned aerial vehicle upward movement's lifting power, will detach aircraft and this check out test set's weight, consequently with unmanned aerial vehicle fixed this check out test set back on, need carry out "zero clearing" earlier and handle, get rid of this check out test set dead weight and unmanned aerial vehicle's weight after, carry out tensile detection again, guarantee measuring accuracy.
And secondly, a pull pressure detection principle in the horizontal direction.
The sensor II8 is mainly used for measurement, the control box 9 transmits data signals acquired by the sensor II8 to an external computer system, and the pulling pressure is obtained through calculation. One end of the sensor II8 is connected with the unmanned aerial vehicle; the other end is connected with the mounting seat 6, when the airplane has a force moving in the horizontal direction, the mounting seat 6 drives the sensor II8 to move in the horizontal direction, namely, the measurement of the tension and pressure in the horizontal direction is carried out.
