On variable-rate spraying equipment and its key technology;

Experimental study on variable-rate spraying equipment response capability;

The response time was obtained by making the variable-rate spraying experiments, the spraying capabilities were also studied.

Characteristics and comparison of pressure-based variable spray

At the foundation of summarized the domestic and foreign related research, this article studied an inter-variable spray control system which is based on the machine vision, also designed the software and hardware test platform for block spray control, determined the image processing algorithms and adjust various algorithms under the simulation in the laboratory.

To verify the accuracy of the algorithm about real-time collection,processing image and to determine the matching relationship between implementation modules of the system and other modules,after the paper analyzes the parallel interface resources and the access methods,it introduces a design of the software and hardware based on the parallel interface to control variable spray operation.

The thesis takes the research of the working accuracy and the influencing factors of variable rate sprayer system used in agriculture.
