Description

TECHNICAL FIELD

[0001] The present application relates to the field of unmanned aerial vehicle equipment testing, in particular to an unmanned aerial vehicle spreader aging test system, a control method, a product and a terminal. BACKGROUND

[0002] With the deep integration of unmanned aerial vehicle technology and precision operation demand, unmanned aerial vehicle spreaders have been widely used in agricultural seeding, fertilization, aquaculture feeding and disaster relief material throwing fields. The core working units of such equipment include motors such as spiral feeding motors and disc driving motors that drive the spreading action, spiral feeding mechanisms including augers that realize material quantitative conveying, bin gates, and electronic control systems that control the spreading parameters. The long-term working stability of the core components directly determines the operation efficiency and scene adaptability. Before leaving the factory, the unmanned aerial vehicle spreader needs to pass the aging test to verify the fatigue resistance of the core components. During the operation and maintenance stage after long-time operation, the aging test is also needed to evaluate the aging degree of the components to avoid sudden failures during on-site operation.

[0003] At present, the aging test of unmanned aerial vehicle spreaders in the industry mainly relies on two types of technical solutions: one is empty load aging test, which is to drive the motor and spiral feeding mechanism to rotate empty by controlling the circuit, and to set a fixed start-stop cycle to test the continuous running ability of the core components. This type of solution is mainly used for preliminary detection of low-cost and low-precision spreaders. The second is a short-time load aging test assisted by manual operation, which manually adds a certain amount of simulated material to the bin, starts the spreader to complete a single spreading, manually weighs the remaining material and records the spreading time, and then repeats the process of adding material, starting and recording. In addition, the existing technology uses a vacuum material extractor to extract material. This technical solution requires multiple extractors and is prone to wear of the extractors, which affects the full load effect during the extraction process and affects the aging test process. The above-mentioned existing technical solutions have technical defects in actual application, and it is difficult to meet the testing needs of the development of unmanned aerial vehicle spreaders.

[0004] In summary, the existing aging test method of unmanned aerial vehicle spreaders has the problems of low automation, insufficient data precision, distorted working condition simulation, poor safety, etc., which makes it difficult to match the testing needs of equipment technology development and diversified application scenarios, and it is difficult to guarantee the reliability of unmanned aerial vehicle spreaders in actual operation. Therefore, there is an urgent need for an aging test method that can realize full-process automatic operation, closed-loop control of key parameters, accurate and traceable test data, and real reproduction of complete operation cycles and complex working conditions.

[0028] <1> Unmanned aerial vehicle spreader: a special device mounted on an unmanned aerial vehicle platform for realizing precise spreading of materials, widely applicable to agricultural production, aquaculture, emergency rescue, ecological restoration, and the like. Its core function is to uniformly deliver seeds, fertilizers, bait, disaster relief materials, and the like to the target area according to the preset parameters through an automatic mechanism, and its performance reliability directly determines the operation efficiency and effect, which is also the focus of the aging test technology of the present application.

[0029] The first aspect of the present application provides an unmanned aerial vehicle spreader aging test system, Figure 1 The structure of the unmanned aerial vehicle spreader aging test system in the embodiments of the present application is shown. The unmanned aerial vehicle spreader aging test system in the present embodiment mainly comprises the following parts:

[0030] In an embodiment of the present application, the unmanned aerial vehicle to be tested spreader 1 is provided with a lower hopper 3 for storing test materials, a feed inlet for the material into the lower hopper 3, and a discharge outlet for the material to be spread outward. Among them, the lower hopper 3 can be a cylindrical or conical cavity, with a capacity of 5-50L designed according to the application scenario to cover the needs of agriculture, aquaculture, disaster relief, etc. The sensor mounting hole is reserved on the wall of the hopper for fixing the material height monitoring device 2 to avoid the influence of the shaking of the hopper body on the data during the test. The feed inlet is provided on the top or upper side of the lower hopper 3, and the discharge outlet is located at the bottom or lower side of the lower hopper 3. A splash-proof fence can be provided around the discharge outlet to make the spreading direction highly accurate to the receiving mechanism 4, and to ensure the material recovery rate.

[0031] In addition, the present application is provided with a test support 5 for firmly installing the to-be-tested spreader 1 on the test support 5 through a clamp. The test support 5 is height-adjustable to adapt to the installation needs of spreaders of different models. An adjustable fixing clamp is provided on the top of the test support 5, which is connected to the body of the to-be-tested spreader through a bolt, and a non-slip rubber pad is pasted on the inner side of the clamp. The outer side of the lower hopper 3 can be provided with a fixed ear seat for stable docking with the clamp of the test support 5.

[0032] In an embodiment of the present application, an upper feeding mechanism 7 is designed to dock with the feed inlet of the to-be-tested spreader 1, for stably lifting the test material from the storage area to the feed inlet of the to-be-tested spreader 1, and ensuring the continuous supply of test materials. Specifically, the upper feeding mechanism 7 includes a vertical lifting device; the vertical lifting device is used for vertically lifting the storage hopper 6 to feed and collect materials. The vertical lifting device can be selected from a bucket elevator, a belt conveyor or a screw conveyor, and the specific selection is adapted according to the characteristics of the test material: for dry materials with uniform particles such as rice seeds and compound fertilizer, a bucket elevator can be selected; for wet and sticky materials such as simulated organic fertilizer, a screw conveyor can be selected; for light materials such as grass seeds, a belt conveyor can be selected and equipped with side baffles and anti-slip textures to prevent the material from falling off. Secondly, the storage hopper 6 can be installed on the vertical lifting device for conveying the test material to the lower hopper 3 of the to-be-tested spreader. The inner wall of the storage hopper 6 is polished to reduce material adhesion, and the volume can be designed as 50-200L according to the test scale. An inclined bottom plate is provided at the bottom of the hopper body to facilitate the convergence of materials to the feed inlet of the lifting device, avoiding accumulation and residue.

[0033] In an embodiment of the present application, the material height monitoring device 2 is installed on the to-be-tested spreader 1 to monitor the accumulation height of the test material in the hopper 3 in real time and generate a height monitoring signal. Specifically, the material height monitoring device 2 can be an ultrasonic position sensor, a capacitive material level switch, or a photoelectric sensor, which is installed on the inner wall top of the hopper 3 or the side of the feed inlet of the to-be-tested spreader 1. The position sensor detects the direction perpendicular to the material surface in the hopper. The position sensor emits a detection signal in real time and receives a reflected signal. The accumulation height of the test material is calculated by the signal propagation time, and the calculated accumulation height of the test material is sent to the control system in real time. The material height monitoring device 2 precisely controls the amount of material in the hopper 3 to ensure that the test material is consistent every time.

[0034] In an embodiment of the present application, the material collection mechanism 4 is placed below the discharge port of the to-be-tested spreader 1 to recover the test material spread by the to-be-tested spreader 1 and ensure the recycling of the material. The material collection mechanism 4 can be a horizontal guide rail 4(a). Specifically, the horizontal guide rail 4(a) is laid along the material collection area directly below the discharge port of the to-be-tested spreader to the material loading area of the vertical lifting device. The total length is designed according to the test site, and a double-track parallel structure is adopted. The guide rail can have two fixed docking points, a material collection point and a material loading point. At this time, the storage bin 6 is a mobile four-wheel cart type storage bin 6(a) designed on the horizontal guide rail, which can be precisely docked to avoid material leakage or docking deviation.

[0035] In an embodiment of the present application, the weight monitoring device 8 is installed on the storage bin 6 to monitor the weight of the test material in the storage bin 6 in real time and generate a weight monitoring signal continuously sent to the control system 9. Specifically, the weight monitoring device 8 can be a high-precision gravity sensor such as a strain gauge type weighing sensor. The measurement range can be adjusted according to specific test requirements. There are four of them, which are evenly installed on the support at the bottom of the storage bin 6, fixed by bolts and horizontally calibrated to ensure the stability of the weighing data. The gravity sensor collects the total weight of the storage bin 6 and the internal material in real time, and obtains the weight data of the actual spread material after deducting the weight of the storage bin 6 itself. The sensor transmits the weight data to the control system 9 to provide a basis for quantifying the test data.

[0036] In an embodiment of the present application, the control system 9 is the core scheduling unit of the entire test system, which uses a PLC controller as the hardware core, and is matched with a touch display screen and a data storage module to realize the collaborative control of each mechanism and the whole process recording of the test data. The control system is connected with the material loading mechanism 7, the to-be-tested spreader 1, the material height monitoring device 2, the material collection mechanism 4, and the weight monitoring device 8. Specifically:

[0037] The control system 9 sends a start instruction to the feeding mechanism 7 in the start stage of the test, and the lifting device delivers the material in the storage bin 6 to the discharge bin 3 of the tested spreader. The material height monitoring device 2 transmits the height monitoring signal to the control system 9 in real time, and the control system 9 immediately sends a stop instruction to the feeding mechanism 7 and a start instruction to the tested spreader 1 when the control system 9 monitors that the material height reaches the preset stacking height, so as to trigger the test.

[0038] In the stop and data collection stage of the test, the weight monitoring device 8 continuously transmits the weight monitoring signal of the recycled material to the control system 9, and the control system 9 compares the data with the preset spread weight in real time. When the actual weight reaches the preset value, the control system 9 sends a stop instruction to the tested spreader 1, synchronously records the key data of this test, including the spread duration, the motor working current, the spiral feeding mechanism rotating speed, the material spread error, and stores the data into the local database.

[0039] In the material circulation and test circulation stage, the control system 9 sends a discharge instruction to the material collecting mechanism after the test is stopped, and the material collecting mechanism 4 can deliver the recycled material to the feeding mechanism 7 to complete the test material circulation. If the test does not reach the preset circulation number or the total test duration, the control system 9 repeatedly executes the above test process of feeding, spreading, weighing and recycling. If the preset test index is reached, the control system 9 controls the end of the test process and generates a test report.

[0040] As shown in FIG. 1, the tested spreader 1 is provided with a material height monitoring device 2, a weight monitoring device 8 and a material collecting mechanism 4. The material height monitoring device 2 is arranged on the discharge port of the tested spreader 1, and the weight monitoring device 8 is arranged on the discharge bin 3 of the tested spreader 1. The material height monitoring device 2 is used to monitor the height of the material in the discharge bin 3 of the tested spreader 1, and the weight monitoring device 8 is used to monitor the weight of the material in the discharge bin 3 of the tested spreader 1. Figure 2 As shown in FIG. 2, which is a structural schematic diagram of another embodiment of the present application. In an embodiment of the present application, the material collecting mechanism can also be a horizontal transmission belt 4(b), and at this time, the feeding mechanism 7 is respectively arranged at both ends of the horizontal transmission belt 4(b). The storage bin is a fixed storage bin 6(b) which can move up and down and is arranged on the feeding mechanism 7. Specifically, the horizontal transmission belt 4(b) is arranged directly below the discharge port of the tested spreader, and the horizontal transmission belt 4(b) is laid at both ends of the fixed storage bin 6(b). The length and width of the horizontal transmission belt 4(b) are designed according to the test site, the belt material is selected from anti-skid texture materials to prevent the test material from sliding, and the rotating speed of the horizontal transmission belt 4(b) is adjustable to adapt to different spreading rates. When the test is performed, the test material falls on the horizontal transmission belt 4(b), the belt is set to run to the left so that the test material falls into the left fixed storage bin 6(b), and when the test material in the left fixed storage bin 6(b) reaches the preset weight, the belt is controlled to run to the right so that the test material falls into the right fixed storage bin 6(b).

[0041] In an embodiment of the present application, as shown in FIG. 3, the tested spreader 1 is provided with a material height monitoring device 2, a weight monitoring device 8 and a material collecting mechanism 4. The material height monitoring device 2 is arranged on the discharge port of the tested spreader 1, and the weight monitoring device 8 is arranged on the discharge bin 3 of the tested spreader 1. The material height monitoring device 2 is used to monitor the height of the material in the discharge bin 3 of the tested spreader 1, and the weight monitoring device 8 is used to monitor the weight of the material in the discharge bin 3 of the tested spreader 1.

[0043] The sowing test starting control module 302 is used for sending a sowing test starting instruction to the to-be-tested sower after the feeding mechanism stops feeding, so as to control the to-be-tested sower to start the sowing test, simulate the key working condition of “starting sowing immediately after full load” in the real work, and solve the problem of existing test empty load starting or non-continuous cycle.

[0044] The sowing test stopping control module 303 is used for receiving the weight monitoring signal in real time, and when the weight of the test material corresponding to the weight monitoring signal reaches the preset weight, a sowing test stopping instruction is sent to the to-be-tested sower to control the to-be-tested sower to stop the sowing test and obtain the key test data, and the accurate quantitative record of the test data is realized.

[0045] The material collecting mechanism control module 304 is used for sending a discharging instruction to the material collecting mechanism after the to-be-tested sower stops the sowing test, controlling the material collecting mechanism to transmit the recycled test material to the feeding mechanism, completing the material circulation, and restarting the feeding mechanism.

[0046] In an embodiment of the application, the control system has a flexible test termination condition setting function. The user can set the total cycle number of the aging test according to the actual application scene demand of the to-be-tested sower, such as simulating 1000 times of field sowing cycle or the total time length such as simulating 500 hours of continuous work, to quantitatively evaluate the reliability of the equipment under long-term high-intensity work. During the test process, the control system will accumulate the sowing cycle number and the total running time in real time, and continuously compare with the preset value: if the preset condition is not reached, the control system will automatically trigger the next round of test to realize the continuous test without manual attendance; if the preset number or time length is reached, the control system immediately terminates the test process, simultaneously calls the stored whole-process test data, performs summary analysis through the built-in algorithm, and generates a test report containing parameter trend curve, key component aging index, fault statistics and the like.
