Description

Ship auxiliary engine operation training simulator

Technical Field

The invention relates to a ship operation training simulator, in particular to a ship auxiliary engine operation training simulator, which is based on a dual mode of simulink and KingSCADA.

Background

In the field of ships, diesel engines are mainly used as main engines for powering ships and as auxiliary engines for supplying electric power to ships. The main diesel engine for providing power for the ship during sailing is mostly a two-stroke diesel engine, and the marine diesel engine is mainly a four-stroke diesel engine. During the navigation of the ship, both the main engine and the auxiliary engine of the ship play an important role in the safety of the navigation, so that professional training needs to be performed on workers related to the turbine before the ship navigates for safe and stable operation of the ship.

The condition of the diesel engine is reflected by a series of parameters during the operation of the diesel engine, and a turbine operator is required to timely judge the reason for the condition when finding that any parameter is abnormal. In view of this, there are two general studies on the working process of diesel engines, one is experimental study, i.e. tests on physical models or testing machines are carried out to draw conclusions. However, the experimental research period of the method is long, the investment of manpower and material resources is large, the adaptability is poor, and meanwhile, the result is only some superficial data, so that the phenomenon of deeper layers is difficult to reveal. And the second is numerical simulation research, namely numerical simulation of the working process of the marine diesel engine through computer simulation, the simulation calculation of the computer is not limited by time, place and experimental conditions, and compared with a means of acquiring numerical values through experimental research, the method is quicker and simpler and saves cost.

Most of the operation training contents in the current turbine simulator, such as diagnosis and elimination of faults, and emergency handling methods, are designed by taking a marine main engine as an object. And the design result of the auxiliary engine part simulator for the ship is often unsatisfactory due to the incomplete mathematical model. In addition, the current turbine training simulator is mainly a computer platform or a single physical platform. Therefore, an economic and efficient simulator for operating and training the auxiliary ship engine is urgently needed, and not only can the requirements of actual teaching and training be well met, but also the physical platform training and the computer platform training can be considered.
