Abstract

The invention relates to a nozzle configuring method and system of a round sprinkling machine. The method comprises the steps of obtaining actual work pressure values of all nozzles of the round sprinkling machine; obtaining expected flow values of all the nozzles; calculating nozzle diameters corresponding to all the nozzles according to the actual work pressure values and the expected flow values; configuring the nozzles of which the model numbers of all the nozzles are matched with the nozzle diameters; calculating actual work flow values of all the nozzles according to the actual work pressure values and the nozzle diameters; calculating deviation coefficients between actual work flow and expected flow; configuring working modes of pressure adjustors corresponding to all the nozzles according to the deviation coefficients, so that the deviation coefficients are within a threshold value range. By means of the nozzle configuring method and system of the round sprinkling machine, theconfiguring precision of the round sprinkling machine is improved.

Description

technical field

[0001] The invention relates to the technical field of control, in particular to a nozzle configuration method and system for a circular sprinkler irrigation machine. Background technique

[0002] The circular sprinkler, also known as the center pivot sprinkler, is by far the most mechanized and automated sprinkler unit. The main water delivery pipe rotates around the central axis when the sprinkler head of the circular sprinkler is spraying. The flow configuration method starts from the center pivot and gradually increases the water spray volume from the inside to the outside of the nozzle. At present, the vast majority of circular sprinkler irrigation machines use low-pressure nozzles installed under suspension, with a nozzle spacing of 2.3m to 4.8m, and the number of nozzles in the whole machine is 30 to 200. The manual configuration is cumbersome and the accuracy is difficult to guarantee. Therefore, establishing a mathematical model of nozzle configura...
