In recent years, virtual reality (VR) is sprouting as a particular computer technology, which is applied in many aspects such as engineering, science, business applications, entertainment, and so on. In this dissertation, we develop a simulation system for power machine operation which integrated digital controller, computer network and virtual reality techniques. This system consists of three main parts: an operation platform, a monitor platform and a VR platform. The operation platform provides the user the sense of presence. The monitor platform controls the signal transmission. The VR platform illustrates overall simulations that combine virtual scenes and the virtual power machine operation. A forklift operation system is built for simulation in the dissertation. The virtual forklift machine is controlled by the operation platform. By using the helmet display, the user would immerse himself in the virtual environment. Finally, we discuss incomplete parts and unsolved programs of this dissertation for the future work.
