The invention relates to an
operating environment sensing based
active control system for a boom
sprayer, which comprises an outside information sensing module, a running parameter measuring module, an active spray
control system module and a running parameter real-
time control module. CAN (controlled
area network)
bus communication of field-operation natural
wind speed measured with a two-dimensional ultrasonic
wind speed sensor and advancing speed of the boom
sprayer measured with a
rotary encoder is realized, and spray parameters are calculated through a precision active spray controller. A spray parameter regulating controller is used for acquiring
pesticide pressure, fan
air volume and spray angle information in real time so as to complete respective PID (
proportion integration differentiation) control, and accordingly, the
spray volume is guaranteed, drift-reduced spray and fine droplet penetrability are realized, and the effect of
settling droplets on
plant leaves is improved. The spray
system based on external environment sensing and automatic active operating
parameter control is high in practical value, simple in structure, convenient in operation and convenient in application.
