Abstract

In order to make up for the shortage of scientific research experiments and teaching in land-based engine room laboratory, a simulation system is designed and developed using B/S mode to simulate scientific research experiments, teaching and operation processes, and designed algorithms to simulate the propulsion characteristics of the main propulsion diesel engine. A large number of experiments were carried out, and the relationship curve between output power and fuel consumption rate of the main engine was obtained in the laboratory. Apache JMeter was used to test the pressure of the simulation system deployed in Dalian Maritime University Cloud. It is found that under the test conditions, the average response time of sample request is 330 ms, which is far superior the design standard of 2 s. There is no abnormal response to all requests, and all indicators fully meet the requirements of the project team. The simulation system fills the gap in the application of panoramic interactive technology in Marine engineering education, and provides a reference for the exploration of "intelligent +" experiment and teaching mode in maritime university laboratories.

Design And Development Of Simulation System

Overall Design of the System

According to the objectives and needs of the experiments to be conducted in the land-based engine room, cloud teaching, simulation operation, assessment, data tracking statistics, and export functions were designed. The requirements were as follows:

  • 1.

    Build a complete cloud-based teaching and lecture system that enables users to learn online with digital materials, virtual reality (VR) objects, 3D models, and other online tools.

  • 2.

    Establish an online simulation operation platform to complete standing by, maneuvering, constant speed, troubleshooting and other contents in land-based engine room through human-computer interaction and simulation operation.

  • 3.

    Design algorithms to simulate the propulsion characteristics and other operating laws of the main propulsion diesel engine (main engine) of engine room laboratory.

  • 4.

    Realize the function of tracking, recording, analyzing and exporting data, provide assessment basis and meet the demand of continuous improvement and upgrading of the system.

  • 5.

    Complete the development of binocular split screen mode and other functions to realize VR simulation operation and enhance user immersion experience.

  • 6.

    Use the B/S model to build an efficient cloud-based experiment and teaching simulation environment. When 400 users are accessing the system concurrently, the response time of a single page should be less than 2 s.
