[Abstract]:With the rapid development of communication technology, computer technology and network technology, the degree of ship system automation is becoming higher and higher, and the ship power mechanical monitoring system as an important part of ship automation. It is a necessary guarantee for the safe navigation of ships. In this paper, the ship power machinery monitoring system is studied and designed by using virtual instrument technology, signal acquisition and processing technology, database technology and 3G wireless communication technology. The related research has theoretical guiding significance for the application of virtual instrument technology in the field of ship monitoring, the networking mode of industrial field monitoring using fieldbus and the rational application of wireless communication technology, and so on, which can ensure the navigation safety of navigation aids vessel. It is of practical significance to promote waterway maintenance. The main research work of this paper is as follows: 1. The development of marine power machinery monitoring system and the present research situation at home and abroad are described, and the feasibility of applying virtual instrument to ship power machinery monitoring system is analyzed and discussed. At the same time, a ship power machinery monitoring system based on Lab VIEW is put forward. 2. The method of field monitoring based on RS-485 bus is studied and analyzed. The star structure of RS-485 bus is adopted to complete the signal acquisition and data processing of the field monitoring system. Data analysis and display. The wireless communication mode is studied, and the 3G wireless mobile communication technology of GSMN GPRSU is compared and analyzed. Using 3G wireless communication module, the communication .3 between the field monitoring system and the remote monitoring center is realized. The software of ship power machinery monitoring system based on C / S architecture is designed. The field monitoring system serves as the client and the remote monitoring center as the server. The network adopts star structure and listens to different ports. The remote monitoring center has established a unified data standard and a reasonable data transmission system for multiple ships while monitoring at the same time, unified the data measuring point items, the data coding rules and the data conversion mode during the transmission of the measured data. The data transmission mechanism of connection verification-sending initial data-periodically sending data is designed. Based on the research of the key technology of the system, this paper designs and develops the ship power mechanical monitoring system based on Lab VIEW, and has been put into practical application, and the operation is reliable and stable. The application results show that the system conforms to the relevant standards and specifications in the field of ship, meets the basic functional requirements of the marine power machinery monitoring system, can effectively guarantee the waterway maintenance work, and improves the automatic level of ship monitoring.
