AI Technical Summary

Technical Problem

When self-propelled boom sprayers operate on curves, the speeds of the inner and outer sides of the boom differ. Current technology cannot achieve consistent pesticide application on both sides of the boom, resulting in uneven pesticide application, especially when satellite signals are unstable.

Method used

By setting initial parameters, obtaining structural, turning angle, and wheel speed parameters, calculating the driving turning radius and angular velocity, and fitting a straight line based on the nozzle flow rate-duty cycle, the nozzle flow rate is adjusted to achieve the actual required flow rate and duty cycle for each nozzle, ensuring uniform spraying.

Benefits of technology

It has improved the uniformity of spraying of self-propelled boom sprayers when operating on curves, and improved the uniformity of pesticide application across the entire plot, avoiding uneven application caused by unstable satellite signals.
