Design of Distribution Bench for Precision Measurement of Micro-Irrigation Sprinkler Irrigation Uniformity Coefficient

Abstract:

Micro-irrigation sprinkler irrigation uniformity coefficient is an important indicator of measuring the irrigation uniformity of micro-irrigation system and is an important parameter of micro-irrigation nozzle design. In order to test micro-irrigation sprinklers irrigation uniformity coefficient precisely, micro-irrigation sprinkler irrigation uniformity coefficient precision test-bed was developed. Test-bed can measure some parameters, such as on-site temperature, pressure, total flow, sub-flow and measurement time accurately. Collecting data through the data collect network. Multi-chip acquisition card is connected with RS485 bus and is connected to the host computer by numerical control system specially developed. The task of numerical control system is to process preliminary collected data, transfer the data to host computer, and coordinate with host computer to complete the task of control. It can also complete the several of control functions independently. Experiments show that the test-bed is reasonable designed, easy to operate and has a high test accuracy.
