Dual Ethernet and dual RS-422 interactive communication technology based on dual CPU

Abstract

[Objectives] With 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.[Methods] In 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.[Results] It 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.[Conclusions] The 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.
