In the related art, the detection sensor in the storage device usually uses a battery as a power supply, and then uses Bluetooth and other means to transmit signals with external devices, which leads to a high manufacturing cost of the storage device.

In the unmanned aerial vehicle set 100 according to the embodiment of the present invention, the power transmission and data transmission between the unmanned aerial vehicle 10 and the detection sensor 24 are realized through the communication between the first near field communication component 12 and the second near field communication component 26 , thereby There is no need to provide an additional battery for the detection sensor 24 as a power supply, which can reduce the manufacturing cost of the storage device 20 .

The detection sensor 24 sends the inventory information of the storage object to the UAV 10 through the communication between the second near field communication component 26 and the first near field communication component 12 . After the detection sensor 24 detects and obtains the inventory information of the stored object, it can send the inventory information of the stored object to the unmanned aerial vehicle 10 through the communication between the second near field communication component 26 and the first near field communication component 12, so that the unmanned aerial vehicle 10 It can be judged whether it is necessary to return to the flight for replenishment or whether to increase or decrease the consumption speed of the stored objects according to the inventory information of the stored objects.

The power of the detection sensor 24 may be less than the preset power. In this way, the power of the detection sensor 24 is relatively small, and the electrical energy transmitted by the first near field communication component 12 and the second near field communication component 26 can be sufficient to support the detection sensor 24 to work. In one embodiment, the preset power may be 27mW.

The first near field communication component 12 and the second near field communication component 26 are both near field communication modules (Near Field Communication, NFC) or radio frequency identification modules (Radio Frequency Identification, RFID). In one embodiment, the first near field communication component 12 and the second near field communication component 26 are both NFC, and the power transmission and data transmission.

In some embodiments, the storage item is a liquid, and the detection sensor 24 is a liquid level gauge. In this way, the level of liquid storage in the container 22 can be detected by the liquid level gauge. The liquid level gauge can measure the liquid level by measuring the pressure difference of the liquid (such as differential pressure method, etc.), or use the buoyancy principle to measure the liquid level (such as the float method, servo method, etc.), or use the electrical parameters of the liquid level sensor to produce changes. method to measure the liquid level (such as capacitance method, inductance method, resistance method, etc.), etc., which are not specifically limited here.

Referring to FIG. 3 , in some embodiments, the UAV suit 100 further includes a spray system 30 for spraying the liquid storage in the container 22 out. Specifically, the spray system 30 may include a liquid infusion tube and a spray head assembly, and the spray head assembly may include a spray head body, a nozzle, and the like.

In some embodiments, the unmanned aerial vehicle 10 may be a plant protection drone. The plant protection drone cooperates with the storage device 20 and the spraying system 30 to spray the liquid storage on crops, trees and other plants. Of course, in other embodiments, the unmanned aerial vehicle 10 can also be used for spray disinfection, for example, for disinfection during epidemic prevention.

Liquid storage can include pesticides, fertilizers or pharmaceuticals. Among them, the pesticide, fertilizer or drug may be liquid and stored directly as a liquid; alternatively, the pesticide, fertilizer or drug may be solid, and the pesticide, fertilizer or drug may be formed into a solution and stored as a liquid. In one embodiment, the liquid storage is a pesticide, such as an insecticide, which can be sprayed by the spray system 30 on crops, trees, etc. to remove pests.

In some embodiments, the storage is solid and the detection sensor 24 is a level gauge. In this way, the level of solid storage in the container 22 can be detected by the level gauge. The material level meter can measure the material level by means of ultrasonic waves, or measure the material level by means of radio frequency admittance, or measure the material level by means of a heavy hammer, which is not specifically limited here. In one example, the material level gauge uses ultrasonic waves to measure the material level. This method transmits ultrasonic waves through ultrasonic transmitters. When the ultrasonic waves reach the surface of the solid storage, the ultrasonic waves will be reflected back, so that the reflected ultrasonic waves can be converted into According to the electric signal, the transmission time of the ultrasonic wave can be determined, and the transmission distance of the ultrasonic wave can be determined in combination with the transmission speed of the ultrasonic wave, and then the material level can be determined to determine the stock of the solid storage.

Referring to FIG. 4 , in some embodiments, the UAV suit 100 further includes a spreading system 40 for spreading the solid storage within the container 22 . The spreading system 40 may include a transfer channel and a silo port, and the transfer channel may transport the solid storage in the container 22 to the silo port, so that the solid storage material may be spread through the opening of the silo port. In addition, the opening degree of the silo opening can also be regulated, and the spreading speed of the solid storage material can be controlled by controlling the opening degree of the silo opening.

In some embodiments, the UAV 10 may be a spreading drone, which cooperates with the storage device 20 and the spreading system 40 to spread the solid storage, eg, for seeding, spreading fertilizer, and the like.

Solid stocks can include pesticides, fertilizers, seeds or pharmaceuticals. In one embodiment, the solid storage is seed, such as rapeseed, which can be spread by spreading system 40 .

Referring to FIG. 5 , in some embodiments, the first near field communication assembly 12 includes a primary energy coil 122 and a primary signal coil 124 , and the second near field communication assembly 26 includes a secondary energy coil 262 and a secondary signal coil 264 . Primary energy coil 122 communicates with secondary energy coil 262 to enable power transfer from UAV 10 to detection sensor 24 . Primary signal coil 124 communicates with secondary signal coil 264 to enable data transfer between UAV 10 and detection sensor 24 .

In this way, the power transmission can be realized through the primary energy coil 122 and the secondary energy coil 262, and the data transmission can be realized through the primary signal coil 124 and the secondary signal coil 264. The energy transmission and data transmission are carried out separately. The solution is relatively easy to implement and the control logic is relatively simple. .

The transmission between the primary energy coil 122 and the secondary energy coil 262 may be unidirectional transmission from the primary energy coil 122 to the secondary energy coil 262; the transmission between the primary signal coil 124 and the secondary signal coil 264 may be bidirectional transmission. In this way, the UAV 10 can supply power to the storage device 20 , and bidirectional data transmission can be performed between the UAV 10 and the storage device 20 .

The primary energy coil 122 and the primary signal coil 124 may be arranged perpendicular to each other or parallel to each other. When the primary energy coil 122 and the primary signal coil 124 are arranged perpendicular to each other, between the primary energy coil 122 and the secondary energy coil 262, between the primary energy coil 122 and the secondary signal coil 264, and between the primary signal coil 124 and the secondary energy coil There is a coupling phenomenon between the 262 and between the primary signal coil 124 and the secondary signal coil 264, but the primary energy coil 122 and the primary signal coil 124 are not coupled, and they do not affect each other. When the primary energy coil 122 and the primary signal coil 124 are arranged parallel to each other, any one coil will be coupled with the other three coils, but the structure between the primary energy coil 122 and the primary signal coil 124 is smooth and easy to install. Among them, it should be noted that when the coupling occurs between the coils, a large amount of energy loss will be caused, and the transmission of the data signal will be seriously disturbed.

Referring to FIG. 6 , in some embodiments, the first near field communication assembly 12 includes a first transmission coil 126 , and the second near field communication assembly 26 includes a second transmission coil 266 . The UAV 10 includes a first processor 18 and the storage device 20 includes a second processor 28 . The first processor 18 is used to modulate the energy signal and the first data signal to obtain a modulated signal and load the modulated signal to the first transmission coil 126 for transmission. The second transmission coil 266 receives the modulated signal to enable power transmission from the UAV 10 to the detection sensor 24 . The second processor 28 is used for extracting and processing the first data signal to realize data transmission from the UAV 10 to the detection sensor 24 .

In this way, power transmission and data transmission can be realized through the same magnetic circuit (ie, the first transmission coil 126 and the second transmission coil 266 ), which reduces the number of coils used, thereby reducing the size of the first near field communication component 12 and the second near field communication assembly 12 . Dimensions of the field communication assembly 26 .

Specifically, the frequency of the energy signal may be lower than the frequency of the first data signal, and the high-frequency first data signal is loaded on the relatively low-frequency energy signal to form a complex wave (ie, a modulated signal). In some embodiments, in order to facilitate the extraction of the first data signal from the modulated signal, the ratio of the energy signal to the operating frequency of the first data signal may be any ratio from 1:8 to 1:10. In addition, the energy The ratio of the voltage of the signal to the first data signal may be 10:1.

The modulated signal is transmitted through the first transmission coil 126 to the second transmission coil 266 . Since the data information in the first data signal is contained in the frequency and phase of the modulated signal, data transmission will not be affected as long as the energy loss of the modulated signal during transmission is controlled within a certain range. In order to reduce the cancellation of the first data signal and the energy signal due to the existence of the phase difference, the initial phases of the first data signal and the energy signal can be the same. is 0.

The first processor 18 and the second processor 28 may refer to a central processing unit (Central Processing Unit, CPU), and may also be other general-purpose processors, digital signal processors (Digital Signal Processors, DSP), application-specific integrated circuits (Application Specific Integrated Circuit, ASIC), off-the-shelf Programmable Gate Array (Field-Programmable Gate Array, FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.

The second processor 28 is used for filtering out the energy signal in the modulated signal to extract the first data signal. Since the frequency of the first data signal is greater than the frequency of the energy signal, the energy signal can be filtered out by means of high-frequency filtering, thereby extracting the first data signal. The first data signal may be a control signal, through which the UAV 10 controls the storage device 20 to work.

The second processor 28 is used for loading the second data signal to the second transmission coil 266 for transmission. The first transmission coil 126 receives the second data signal, and the second processor 28 is configured to process the second data signal to realize data transmission from the detection sensor 24 to the UAV 10. In this way, the detection sensor 24 can transmit data to the UAV 10. For example, the detection sensor 24 can send the detected inventory information of the stored objects to the UAV 10, so that the UAV 10 can determine whether or not according to the inventory information of the stored objects. Need to resupply or whether to increase or decrease the rate of consumption of storage.
