Embodiment 1
[0034] figure 1 It is a flow chart of a method for determining the calibration coefficient of a flowmeter on a drone provided in Embodiment 1 of the present invention, which is applicable to calibrating a flowmeter on a drone. The device for determining the calibration coefficient of the flowmeter can be implemented by means of software and / or hardware, and can generally be integrated in the drone.
[0035] Such as figure 1 As shown, the method of this embodiment specifically includes:
[0036] S110. When the flight controller determines that the spraying of all the materials to be sprayed carried by the UAV is completed, acquire the cumulative measured flow rate fed back by the flow meter corresponding to the materials to be sprayed.
[0037] Among them, the drone refers to a plant protection drone, which is used to spray the substance to be sprayed during the plant protection operation. The substance to be sprayed can be the agent required for the plant protection operatio...
Embodiment 2
[0055] figure 2 It is a flow chart of a method for calibrating a flowmeter on a drone provided in Embodiment 2 of the present invention, which is applicable to calibrating a flowmeter on a drone. It is performed by a calibration device, which can be implemented in software and / or hardware, and generally can be integrated in the UAV.
[0056] Such as figure 2 As shown, the method of this embodiment specifically includes:
[0057] S210. The flight controller acquires the calibration coefficient of the flowmeter corresponding to when the UAV sprays the substance to be sprayed with the set medicament type, wherein the calibration coefficient of the flowmeter is provided by any embodiment of the present invention on the UAV. The method for determining the calibration coefficient of the flowmeter is determined.
[0058] The method of this embodiment can be used to calibrate the sprayed flow measured by the flowmeter when the UAV is in formal plant protection operation. Accordi...
Embodiment 3
[0069] image 3 It is a flow chart of a calibration method for a flowmeter on a UAV provided by Embodiment 3 of the present invention. This embodiment is embodied on the basis of the above-mentioned embodiment, taking the calibration of a Hall flowmeter on a plant protection UAV as an example Explain.
[0070] Among them, the relationship between the liquid flow measured by the Hall flowmeter and the frequency of the pulse signal is q=k 0 f, q is the flow rate, f is the pulse signal frequency, k 0 is the flow coefficient, which is a fixed value, and has been calibrated when the Hall flowmeter leaves the factory.
[0071] Such as image 3 As shown, the method of this embodiment specifically includes:
[0072] S310. When the flight controller determines in the spraying test that the spraying of the first medicament to be sprayed carried by the UAV is completed, the accumulative measured flow rate fed back by the Hall flowmeter is acquired.
[0073] S320. The flight controll...
