AI Technical Summary
Existing plant protection drones have problems such as uneven mixing of liquid fertilizers and pesticides, inconsistent concentrations, inaccurate manual setting of spraying parameters, inability to monitor in real time, and low degree of automation during liquid fertilizer and pesticide spraying, resulting in crop damage and resource waste.
The system employs a variable-rate liquid fertilizer and pesticide spraying system based on magnetic mixing, which includes a fertilizer and pesticide mixing device, a spraying device, an image information acquisition device, and a control device. Through magnetic stirring, concentration sensing sensors, and laser feedback, it achieves uniform mixing of liquid fertilizer and pesticide, real-time concentration control, and on-demand spraying. Combined with image information acquisition and automated control, it enables precise variable-rate spraying.
It enables uniform mixing and real-time concentration control of liquid fertilizers and pesticides, improves spraying accuracy and automation, reduces manual intervention, saves resources, and lowers the risk of pesticide damage and the rate of missed spraying.
