Drop orientation control is the core of automatic control technology of drop tester. Currently the most common way of fixed drop orientation is manual. To reduce the influence of complex manipulation and artificial error, a control scheme of edge drop of packaged hexahedron based on virtual instrument LabVIEW was designed. The signal measured by beam type sensor is transmitted to host through a data collecting card. Then, the collected data can be displayed, monitored, and controlled real-time through the software LabVIEW.
