Prescription map operation method and device

Abstract

The invention discloses a prescription map operation method and device. The method comprises the steps of obtaining the location information, height, wind speed and wind direction angle of a current location; correcting a target operation location according to the location information, height, wind speed and wind direction angle of the current location; querying operation information in a prescription map according to the corrected target operation location, and controlling an agricultural implement to conduct operation according to the operation information. The device is used for executing the method. According to the prescription map operation method and device, the target operation location can be corrected according to the obtained location information, height, wind speed and wind direction angle of the current location, the operation information is queried in the prescription map according to the corrected target operation location, the agricultural implement is controlled to conduct the operation according to the operation information, and the target operation location is corrected according to the influence of a wind field, so that the operation precision in a farmland is improved.

Description

technical field [0001] The invention relates to the technical field of modern agriculture, in particular to a prescription map operation method and device. Background technique [0002] Precision agriculture is a new trend in the development of agriculture in the world today. Technology-intensive and ecologically-intensive agriculture based on modern information technology has been widely used in fields such as fertilization, plant protection, precision seeding, precision farming and water management. The prescription map is an important part of the precision agriculture operation process. [0003] When using drones to spray pesticides, the spraying information is obtained from the prescription map, but due to the influence of the local wind field, the actual drop point of the sprayed pesticides will deviate from the target operation position, which does not achieve the purpose of precise operation , when the wind is strong, pesticides may also drift out of the field, causi...

AI Technical Summary

Problems solved by technology

[0003] When using drones to spray pesticides, the spraying information is obtained from the prescription map, but due to the influence of the local wind field, the actual drop point of the sprayed pesticides will deviate from the target operation position, which does not achieve the purpose of precise operation , when the wind is strong, pesticides may also be displaced out of the field, causing pollution

At present, changes in the local wind field cannot be responded to in real time on the prescription map, which makes the spraying operation based on the prescription map very uncertain, and the operation accuracy is greatly limited.
