Research On Parallel And Distributed Simulation System Based On Multi-MCU

The simulation technologies are developing from traditional serial and single computer simulation to parallel and distributed computers simulation, because the simulation objects are needed more accurate than before. The research on parallel and distributed simulation systems based on multiple computers has become popular.Marine simulator is a device which simulates the functions of devices in engine room. There are a large number of complex objects, such as main propulsion plant, boiler and steam system and ship power station and so on. The simulator must take a lot of time to run and dispatch the simulation algorithms, so it is difficult to take into both real-time and fidelity. The use of multiple computers can split a complex object into several parts, and every part works in parallel, finally complete the simulation through the exchange of data. The method of hardware simulation instead of software simulation can improve the real-time. This is the significance of research on parallel and distributed simulation system based on Multi-MCU.This thesis is a preliminary research on parallel and distributed simulation system based on Multi-MCU. An experiment board is designed and produced. The diesel generator is selected as the simulation object to verify the feasibility of the system.Firstly, the article introduces the general design of the system. Secondly the design and implementation of hardware is introduced. The communication among Multi-MCU is achieved by an external memory. Thirdly the diesel generator is modeled and simulated on the MATLAB. Finally, the design and implementation of software is introduced, including the design of I2C bus and RS-485 serial communication, the system is simulated on the experiment board. The diesel generator is broken down several parts, each MCU is responsible for one part, and completes the simulation through exchanging data, and returns the results to PC. The result verifies the feasibility of parallel and distributed simulation system based on Multi-MCU.
