对跌落方位的控制是跌落试验机自动控制技术的核心，目前大多采用人为固定跌落方位。为了降低操作复杂程度和人为误差等因素的影响，设计了一种基于虚拟仪器LabVIEW的包装六面体棱跌落的控制方案。方案采用梁式测力传感器将测得的信号通过数据采集卡传输到主机端，然后用LabVIEW软件对采集的数据进行实时显示、监测与控制。

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.
