Application of USB Tester Software Based on LabVIEW and DLL Technology to Torpedo

To meet the ever-growing requirements of calculation and transmission as well as function enhancement and limitation of weight and size for a torpedo，the authors redeveloped the upper monitor software of portable USB tester by using the combined LabVIEW and Visual C++ programming method in design of a portable measuring and controlling equipment of a torpedo. Hence, the operation on the non-NI hardware board was realized in LabVIEW or LabWindows/CVI environment, which proposes a new way to balance between development efficiency and cost reduction. Several debugging processes verified that the tester fully meet the needs of different test tasks for different types of torpedo launchers. This redevelopment is able to be applied to other function board besides USB. It is provides reference for the development of torpedo software.
