Description

{DRONE PERFORMANCE TEST APPARATUS}

The present invention relates to a drone performance testing apparatus, and more particularly, to a device capable of precisely measuring a movement and a performance of a drone even if the drone does not actually fly by air.

Drone (drone) is a generic term for unmanned aerial vehicles. The drones, which are generally controlled by radio waves, were initially used for military interventions for airborne, anti-aircraft, or missile intercept exercises.

As wireless technology developed gradually, it was used not only for intercepting exercises but also for destruction of target facilities by attaching military reconnaissance devices and various weapons.

In recent years, the use of drones has expanded, and small drones have been developed and used for leisure purposes, and the popularity of drones is gradually widening to the extent that drone control competitions are held.

Currently, shipping companies are planning and implementing a shipping mechanism that uses drones to transport the ordered goods. In such a delivery system, data information about the output of the drones and the moving direction, the moving speed, the movable distance, the payload value, etc. with respect to the battery is required to be precise.

In actual transportation, preliminary performance tests are required since the drones must be capable of moving stably to overcome the weight of the transported object within a predetermined time to the destination.

Conventionally, these performance tests were conducted by indirectly collecting performance data on a computer monitor by using a propeller's output-related software simply by fixing the drone in the laboratory or by operating the drone directly outdoors.

In the former case, there is a limitation in measuring the precise performance of the drones such as the moving direction and the payload value. In the latter case, when the drones are crushed due to inoperability, the drones and the transportation objects are damaged.

Therefore, there is a demand for a device capable of measuring the performance more precisely while reducing the test cost by preventing the breakage of the drone.

Referring to FIGS. 2A and 2B, a gyro sensor 219 may be disposed on the bracket body 210 of the fixing unit 200. The gyro sensor 219 senses the three-dimensional movement of the bracket body 210 through sensing, and sends the motion information to the measuring unit 500. The experimenter can more precisely measure the motion of the dron through the information collected by the gyro sensor 219. [

The above-mentioned fixing portion 200 is merely an example, and the scope of the present invention may include all other types of fixing devices capable of fixing the drone.

4, the rotating member 300 may include an upper block 310, a middle block 320, a lower block 330, and a link pin 340. In the embodiment of the present invention, the upper block 310, the intermediate block 320, and the lower block 330 may all be provided in a circular shape in cross section, but the present invention is not limited thereto.

The upper block 310 may be a portion that is fastened with bolts 214 (see FIG. 2B) and connected to the bracket body 210. The intermediate block 320 may be disposed between the upper block 310 and the lower block 330 and the penetrating portion 324 may be formed at the center of the intermediate block 320.

The upper block 310 is inserted into the penetration portion 324 of the intermediate block 320 and is rotatably disposed. At this time, though not shown in the drawing, a ball bearing is disposed on the inner peripheral surface of the intermediate block 320 to smooth the rotation of the upper block 310.

The intermediate block 320 may be fixed to the lower block 330 by a link pin 340. A lower portion of the lower block 330 is provided with a coupling groove 332 and may be a portion into which the motion beam 410 is inserted.

When the drone performs a yawing motion during the performance test of the fixed drone, the upper block 310 is rotatably disposed on the intermediate block 320, so that such movement is smoothly performed, The precision of the performance test result can be enhanced.

5A and 5B, the motion unit 400 may include a motion beam 410, a motion ball 412, a motion stage 420, and a rimber 430.

The motion beam 410 is inserted and connected to the lower end of the rotary member 300, specifically, the insertion hole 332 (see FIG. 4) of the lower block 330, (Not shown). The motion ball 412 may be inserted into the operation space 422 formed on the upper portion of the motion stage 420.

A rim portion 430 may be disposed at an upper end of the motion stage 420. When the motion beam 410 is vertically erected, it functions to support the motion beam 410, and the motion ball 412 can be moved in the vertical direction So that a space in which the motion beam 410 can be inclined can be secured when the motion beam 410 is tilted.

The lower end of the motion stage 420 is connected to the upper end of the support flange 440 and the lower end of the support flange 440 is connected to the upper end of the load cell 523 of the measurement unit 500.

When the motion beam 410 linked to the fixing unit 200 and the rotary member 300 moves according to the operation of the drones, the motion ball 412 moves in the operation space 422. When this motion occurs, The stage 420 and the support flange 440 receive a certain force in a direction in which the dron is moved integrally.

Here, the movement of the motion ball 412 allows the dron to visually observe moving in a specific direction (for example, east, west, north, and south). More information on the directionality of the drones can be obtained with precision through the gyro sensor.

The force transmitted to the motion stage 420 and the support flange 440 through the motion ball 412 is applied to the load cell 523 as it is. The experimenter detects the force, the payload value, and the like applied in the moving direction of the dron through the measured value at the load cell 523.

That is, the movement direction of the dron can be obtained through the inclination direction of the motion ball 412 and the gyro sensor, and the starting output value of the dron, the payload value, etc., The load cell 523 can be obtained by calculating the pulling or pushing force of the load cell 523 when the load cell 523 is tilted in one direction or moved upward.

Here, the load cell 523 may be connected to a measuring device disposed inside the lower case 530 by wire to transmit data.

Next, the measuring unit 500 may include an upper case 520, a load cell 523, and a lower case 530.

The upper case 520 may be a portion connected to the support flange 440 of the motion stage 420. The load cell 523 is connected to the lower end of the support flange 440 and may be provided in a zigzag shape.

The load cell 523 is formed in a zigzag shape in order to buffer the force applied to the load cell 523 in response to the change of the position of the motion stage 420 and the support flange 440 according to the movement of the drones. That is, the deformability of the load cell 523 is increased to prevent the load cell 523 from being damaged.

In addition, a measuring device for measuring the drones performance is built in the lower case 530, and a display unit 510 may be disposed on the lower case 530 so that the dron operation information of the tester can be visually confirmed. The measuring device calculates the current moving direction and the payload value of the drone through the information transmitted from the load cell 523, and displays the current moving direction and the payload value through the display unit 510.

Here, the measurement method is as follows. When the experimenter raises the drones with the controller, the load cell 523 is applied with a force as much as the force of the rising of the drones, and the load cell 523 is pulled upward. The value of the force applied upward to the load cell 523 is calculated by the measuring device and displayed on the display unit 510 so that the experimenter can know the take-off speed, the payload value, and the like at the time of the rise of the drones.

Also, assuming that the experimenter moves the dron in the upward direction in the direction of the controller by the controller, for example, when the dron is tilted, the motion stage 420 and the support flange 440 are inclined Which is applied to the load cell 523 with a relatively different force toward the tilted direction.

At this time, the measuring device measures the moving speed and the moving direction of the current dron by applying a trigonometric function to the measured value in the load cell 523.

Meanwhile, a level system 550 may be disposed on the upper end of the lower case 530. The tester can check whether the initial placement state of the drones is leveled before the dron performance test through the leveling system 550, which can contribute to more accurate performance test results.

Referring to FIGS. 6A and 6B, the leg portion 600 may be disposed at a lower end of the measurement unit 500 to support the measurement unit 500. The leg portion 600 includes a center leg 620 disposed at the lower center of the measurement portion 500 and a plurality of side legs 610 disposed along the lower end of the measurement portion 500, And a support plate 630 connecting the lower end of the intermediate lever 620 and the lower end of the intermediate lever 610.

In the embodiment of the present invention, one center leg 620 and four side drags 610 are integrally connected to the support plate 630, so that the shaking of the apparatus between the drones can be alleviated. This will aid in more precise performance test measurements.

The caster unit 700 is disposed below the support plate 630 to support the leg unit 600. The caster unit 700 includes a caster body 740, a wheel 724, A supporting body 722, a lift block 730, and a lift pin 710. [

The caster body 740 may be bolted (not shown) to the lower end of the support plate 630 and the wheel support 722 may be disposed on one side of the caster body 740, And can be mounted on the support 722 rotatably by a shaft on the wheel 724.

The lifting pin 710 is disposed on a lower portion of the caster body 740. The lifting pin 710 is threaded on an outer circumferential surface of the lifting pin 710. When the tester rotates the lifting pin 710, And can be moved up and down with reference to the support plate 630.

At this time, the lower end of the lifting pin 710 is connected to the lifting block 730. When the lifting pin 710 is lowered by rotating the lifting pin 710 in one direction, the lifting block 730 is brought into close contact with the lower lifting block 730, Thereby restricting the rotation of the drone performance testing apparatus 100, thereby allowing the drone performance testing apparatus 100 to be fixed in position.

When the tester rotates the lift pin 710 in the other direction to lift the lift pin 710, the lift block 730 also moves upward so that the wheel 724 can rotate again. At this time, the drone performance tester 100 You will be able to move to another location.

Here, when the output of the drone is high, the drone performance testing apparatus 100 may be heard in the upward direction. In this case, since it is difficult to accurately measure the performance, the castor unit 700 may further include a weight weight 750 fitted and disposed in the lift pin 710.

In the case of testing a dron with a high output, the tester can fit the weight 750 to the lift pin 710 to increase the overall weight of the dron performance tester 100, thereby preventing the device from being heard during the test.

7A and 7B show a state in which a drone is mounted on a drone performance testing apparatus 100 of the present invention to test the performance of the drone.

7A shows a state in which the lower portion of the dron D is fixed to the fixing portion 200 and data is collected when the dron D is lifted. When the tester operates the drone (D) through the controller, the payout value of the output of the drone (D) can be measured. In the present invention, the payload value may be defined as the weight of the weight of the drone and the weight of the object that can be transported by the drone. That is, the maximum value of the weight of the object that can be transported by the drone can be calculated through this test.

7B shows a state of collecting data related to the moving direction of the drones D. Fig. When the tester switches the direction of the dron D with the controller, the motion ball 412 shown in Fig. 5B moves, so that the force of the force applied to the load cell 523 by the support flange 440, The direction of movement is detected. At this time, the moving speed of the dron with respect to the moving direction can be grasped through the extent to which the support flange 440 pulls the load cell 523.

This enables to comprehensively and precisely calculate the moving direction, the moving speed, the movable distance, the payload value, etc. of the dron in relation to the output and the battery by linking with the related software.
