Abstract

The invention provides a plant protection unmanned plane spraying operation method based on a wireless sensor network. A plurality of wireless sensor nodes are arranged in an operation region for collecting and feeding back spraying object concentration in real time, an unmanned plane is subjected to flight-path angle regulation according to the spraying object concentration, and if the spraying object concentration differential value is higher than the set threshold, the original flight-path angle is changed, so the unmanned plane flies in the direction with the low spraying object concentration to reach the goal of uniformly spraying in the operation region. The plant protection unmanned plane spraying operation method has the advantages that the autonomous operation capability of the unmanned plane in farmland operation environment is improved, the problem of nonuniform spraying caused by factors such as wind direction during the operation of the unmanned plane is solved, and the operation effect of the unmanned plane and the yield of crops are ensured.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a plant protection drone spraying operation method based on a wireless sensor network. Background technique [0002] The trajectory planning of agricultural UAVs mostly adopts the method of pre-planning by the ground station system before the operation, that is, the ground station system performs trajectory planning according to the specific tasks of farmland operations before take-off. During the operation, the UAV does not make autonomous trajectory planning adjustments. [0003] In the process of using drones to implement plant protection, some spraying areas often have missed spraying, re-spraying, or spraying outside the operation boundary, which will not only lead to unsatisfactory plant protection effects, but even cause crop yields to decrease. Summarize the other The reason is mainly due to the poor autonomous operation ability of drones in the farmland operation ...
