This paper proposes a test device and control method for centralized control of marine engine room equipment based on mixed reality,which can obtain real-time engine room information,establish a mathematical model based on collected data,and control the engine room equipment according to the projected 3D model of the en-gine room.This paper studies the design scheme and method of an MR-based centralized control system for marine engine room equipment,as well as the framework and algorithm for identification of marine engine room equipment state indication by applying Faster R-CNN target detection network deep learning.The iterative research and devel-opment of the centralized control process,the three-dimensional model construction and its optimization,and the centralized control method and its practical training enabled the test and validation of the centralized control function of MR engine room equipment.This paper applied mixed reality technology to the operation of engine equipment,management of engine room resources and other practical training activities.It enhances the interactive effects of spa-tial analysis and visualization of the engine room,and further stimulates interest in practical training and operation.
