Development of test system for automatic pick-up plug seedlings

A test system has been designed for studying the working process and performance,optimizing the structure and motion parameters of the automatic pick-up single plug seedlings device.PC and A/D card are used as the main hardware,and LabVIEW as the software development platform in the system.The system provides the functions such as selecting the automatic or manual control modes,setting the corresponding experimental parameters,recording,analyzing and storing the test results automatically.It provides a good man-machine interface as well.On the system the experiments about the displacement,the velocity and the structure of picking device can be carried out conveniently.Technical parameters:the control range of displacement is from 0 to 100 mm with 10-3 mm control precision.The control range of speed is from 0 to 200 mm·s-1 with 10-3 mm·s-1 control precision,and the measurement range of force is from 0 to 100 N with 10-5 N test accuracy.System testing results show that,it has high precision and sensitivity in controlling and measuring to test parameters.
