The use of drones to carry out fly-proof plant protection at night has the advantages of suitable temperature at night, facilitating the elimination of night-time pests, and facilitating the prevention of window periods.
Night plant protection
Therefore, in the peak season of plant protection , the plant protection workers who use the P20 plant protection drones that support the autonomous operation will choose to carry out plant protection operations at night.
However, when working at night, the flying height of the P20 sometimes becomes unstable. So how do you solve this situation?
main reason:
At night, the time of condensation is dew. At this time, the humidity of the air is very large, and water mist is easily formed in the air, and dewdrops are easily formed on the foliage of the plant.
The terrain module (or ultrasonic) installed on the bottom of the P20 will contaminate the dew on the leaf surface during take-off and landing. The surface of the ultrasonic probe is contaminated with excessive dew water to affect the ultrasonic height.
Therefore, nighttime operations using a P20 flying in the ground may be highly unstable when exposed to dew in this environment.
Solution:
1. When working at night, it is recommended to check the surface of the ultrasonic probe for dew on every few shelves. If there is dew, please wipe it off in time.
2. Under the premise of not affecting the plant protection effect and equipment safety, reduce the height of the imitation ground as much as possible. If set to a height of 2.1 or 2.2 meters, reduce the effect of water mist on the ultrasonic waves.
