Feedback regulation system for spraying parameters based on online droplet mass deposit measurements

In order to effectively optimize and regulate spraying parameters based on actual performance improve pesticide utilization rate, in this research, a feedback regulation system for the of was designed droplet mass deposit online measurement. The consisted an measurement module, wireless transmission decision module. First, deposits sampling points were measured. Based deviation between measured expected mass, determined by parameter regulated value regulating pulse duty cycle pump motor using micro control unit relay. Evaluation tests conducted indoors indoor platform outdoors unmanned aerial vehicle. results showed that relative errors after 6.84% 11.48% outdoor tests, respectively. Therefore, optimal observed regulation. This research provided experimental quickly also technical references precision spraying.
