Virtual instrument is the newly notional instrument connecting computer technology with instrument technology. It makes the effective integration of computer hardware resource, hardware resource of instrument and control system and software resource of virtual instrument realized. This paper introduces the virtual instrument inter- act environment, layouts structure of hardware - in - loop simulation of underwater vehicle and technology of reflective memory real - time network, completes the design of virtual instrument of hardware - in - loop simulation of underwater vehicle based on labview. It shows that the design can make intuitionistic, efficient, real - time examination and monitoring of simulation by its powerful user - machine interaction. It achieves intelligent measuring and controlling of the system of real - time hardware - in - loop simulation.
