Design and implementation of immersive interactive simulation system for ship engine room

  Objectives  In order to solve the problems of the traditional interactive ship engine room simulation system such as its single simulation form and poor immersivity and realism, a new immersive interactive ship engine room simulation system is designed and implemented, divided into the hardware-in-the-loop （HIL）simulation system and 3D virtual reality (VR) system.

  Methods  Real-time simulation technology is adopted to realize the real-time connection between the VR system and HIL simulation system through a high-speed network. At the same time, an immersive stereo projection system and multi-station VR system are combined and integrated with the data.

  Results  This design realizes the real-time interaction and cooperative operation of the whole system, and the real-time synchronization of the system state between the HIL and VR systems. The internal synchronization characteristics of the VR system are given, and the real-time synchronization of 3D images is realized. Meanwhile, a collaborative interactive operation function of the multi-station VR system is added.

  Conclusions  The new immersive interactive ship engine room simulation system proposed herein has guiding significance for ship operation and maintenance management and personnel operation training.
