Application of embedded internet technology in ships

t  Objectives   tWith the continuous improvement of the electrification level of the Integrated Power System(IPS), real-time acquisition of equipment information and intelligent control of ships are prerequisites for ensuring safe and stable operation of equipment and correct decision-making.t  Methods   tIn this paper, a dual-CPU-based dual Ethernet and dual RS-422 interactive communication system was built, and the hardware and software implementation of this interactive communication system was studied.t  Results   tIt can quickly switch to the standby network in the event of a fault, thereby ensuring real-time transmission of on-site information and enhancing the anti-jamming capability and communication reliability of the system.t  Conclusions   tThe communication system has high use value in the occasions where real-time online monitoring and data transmission are required, such as in the ship's integrated power energy management system, distributed substation, power conversion device and industrial field monitoring system.
