外文摘要：A kind of real-time measurement system and method for height from spray boom to crop canopy was provided in present invention patent, which includes the following steps. Step 1 : Calibration for ultrasonic ranging sensor; Step 2 : Determination of included angle for two ultrasonic ranging sensors; Step 3 : Collection of relative height between spray boom and crop canopy; Step 4 : Anti-interference processing for height data; Step 5 : Calculation of relative height from spray boom to crop canopy. Its characteristic lies in : two ultrasonic ranging sensors with a certain angle are installed at each end of the spray boom, the height of crop canopy was acquired under the control of control unit, and the relative height from spray boom to crop canopy was obtained by the anti-interference analysis and data conversion, the accurate monitoring for relative height from spray boom to crop canopy was realized while the spray boom is tilted. It breaks through the technical bottleneck that the relative height of the spray boom and the crop canopy cannot be accurately obtained when the spray boom tilts due to turbulence in the field operation of the spray boom sprayer, and lays a technical foundation for the dynamic adjustment of the balance and height of the spray boom.
