The Simulation Of Monitoring And Alarming System Based On PLC For High Speed Marine Engine

With the rapid development of computer network technology and communication technology, modern ship management also rapid development to digital networked directions. Monitoring and alarming system for marine engine already from centralized monitoring system to distributed monitoring system to today’s distributed fieldbus control system, formed a digital automated monitoring mode.Because the high-speed ships of application and promotion in the country, for high-speed ship performance requirements also will be increasingly. High-speed Monitoring and alarming system mainly used in medium-sized ships, medium privateers, auxiliary and high speed craft of power plant. Monitoring and alarming system for marine engine as an important part of ensure high-speed ships safe operation, have an essential impact on the overall performance of the high-speed ships. In foreign monitoring and alarming system adopts the network structure, enabling the marine engine monitoring, status display, fault alarm, save data and print functions, improve the overall reliability of the monitoring alarm system. In addition, a new generation of ships monitoring alarm system not only has the network, information technology features, and make alarm system monitoring, fault diagnosis and simulation functions together, forming a multi-functional, intelligent ship automation control system. Currently high quality Monitoring and alarming system for marine engine basically been monopolized by foreign, some of the domestic enterprises have also committed to Monitoring and alarming system for marine engine research and development, but to some extent still have a big gap between the level of foreign. In training and teaching of ship operator, the application of simulation operating system than the real ship training has more advantages, not only can freely arrange training activities, but also went to great savings in time and cost limits and the consequences brought about by wrong operation. Therefore, the development of high speed marine engine monitoring and alarming system for training high-speed machine operator and real ship alarm monitoring systems further research have some significance. The authors refer to a high-speed ships cabin structure and Marine engine auxiliary engine, by access relevant information, design PLC as the core Real Info configuration software design Interactive interface of monitoring and alarming system.In this paper, reference domestic and international mainstream alarm monitoring products, design system is mainly for the important parameter get on monitoring and alarm, record, print, trend curves, simulation. At the same time get on monitoring alarm function to auxiliary engine as well as some important parameters. On the other hand, use virtual reality technology by 3ds max modeling software set up high-speed ships centralized console, power station, and so on. Then use VRP-Builder to the model get on scene and scripts editing, and to achieve communication between the scene and the PLC monitoring alarm system, realize model virtual operating and monitoring alarm systems of three-dimensional virtual simulation.
