Gao, M., 2020. Application analysis of plc technology in automatic control of ship auxiliary machinery. In: Bai, X. and Zhou, H. (eds.), Advances in Water Resources, Environmental Protection, and Sustainable Development. Journal of Coastal Research, Special Issue No. 115, pp. 130-132. Coconut Creek (Florida), ISSN 0749-0208.

In the process of ships sailing on the sea, auxiliary machinery and equipment play an indispensable role, which not only can provide necessary services for ships, but also can ensure the normal navigation of ships. As an advanced technology, PLC technology of mechanical automation control has obvious characteristics, flexible and convenient operation and wide functions. The application of PLC technology in the automatic control system of ship auxiliary machinery is studied and analyzed to provide more favorable support for stable navigation of ships. In the application process of PLC ship auxiliary machinery control system, incomplete information, insufficient data and other uncertain factors will also have a great impact on the system, which will threaten the reliability of the system. Therefore, it is of great significance and far-reaching influence to strengthen the application of PLC technology in automatic control devices of ship auxiliary machinery.
