A dual Ethernet and dual rs-422 mutual conversion communication system and method

Abstract

The invention relates to an embedded technology, and specifically relates to a double Ethernet and double RS-422 mutual transformation communication system and method. The communication system comprises a first user interface unit, a network port transformer unit, an Ethernet controller unit, a main controller unit, an RS-422 isolation transformation unit, a network data transmission cable and a second user interface unit which are sequentially connected. The communication system is flexible and convenient in parameter setting, can switch quickly, stably and seamlessly, not only ensures the reliability and the rapidity of the communication system, but also can adapt to working occasions with complex electromagnetic environments, long transmission distance and high communication accuracy. The communication system has a high anti-interference ability and reliability, can effectively detect and position a fault and timely switch to a standby network, thereby ensuring the timeliness of information transmission in the field. The communication system is used in occasions such as a ship integrated power energy management system, a distributed substation, a power electronic transformationdevice and an industrial field monitoring system which have very high requirements for real-time data.

Description

technical field [0001] The invention belongs to the field of embedded technology, and in particular relates to a double Ethernet and double RS-422 mutual conversion communication system and method. Background technique [0002] After nearly a hundred years, especially in recent decades of exploration and practice, navies around the world have reached a consensus: an important development direction of the future ship power system is the integrated power system (Integrated Power System: IPS). With the idea of ​​"modularization and integration", the ship's integrated power system simplifies the structure of the ship's power system, provides energy guarantee for shipboard high-energy weapons, and greatly improves the maneuverability, concealment and vitality of the ship. [0003] With the continuous improvement of the electrification level of the ship's power system, the ship puts forward higher technical requirements for the quality, reliability and vitality of the power supply...

AI Technical Summary

Problems solved by technology

This is due to the complexity of these multi-system functions, which will inevitably bring serious electromagnetic compatibility problems, which will pose a threat to the normal operation of communication equipment;

[0006] 2. During the voyage of electric propulsion ships, they are disturbed by various random uncertain factors such as wind, waves and ocean currents, which will lead to an imbalance between the ship's output power and load power, and even undervoltage, overvoltage, etc. Severe conditions, which can cause serious damage to communication equipment;

[0007] 3. The working environment of ship data acquisition equipment is complex and changeable. Due to the influence of many factors such as transmission distance and site conditions, the transmission channel may be interrupted, such as network congestion, network cable disconnection, network interface connector loosening, network interface hardware circuit failure etc., resulting in lower real-time performance and reliability of the network, and even the network cannot work normally.
