Communication device and relay protection device

Abstract

Provided is a communication apparatus and a relay protection apparatus, the communication apparatus supports at least one of communication protocols and provides functions of at least two dedicated communication profile components for each of the communication protocols, and the communication apparatus comprises: a configuration module for setting an operational parameter of the communication apparatus, wherein the operational parameter indicates that which one of the at least two dedicated communication profile components is used for the communication apparatus; a management module for causing the communication apparatus to operate as the one of the at least two dedicated communication profile components according to the configuration of the configuration module; and a communication function module for providing the functions of the at least two dedicated communication profile components, wherein the management module causes the communication apparatus to operate as the one of the at least two dedicated communication profile components by selecting the function provided by the communication function module according to the configuration of the configuration module.

Description

technical field [0001] The present invention relates to the technical field of industrial communication, and more specifically relates to a communication device and a relay protection device, which support at least one communication protocol, and for each communication protocol, the communication device provides at least two types of dedicated communication modules Function. Background technique [0002] Currently, there are many communication module products on the market that can be applied to industrial automation, substation automation, or intelligent protection, such as MiCom Px20, Px30, Px40, Sepam20 / 40 / 80, and Vamp50. These existing communication module products can support Modbus, DNP3 and IEC103 communication protocols. [0003] With the evolution of technology, these existing communication module products may be gradually replaced by other new communication module products, but because the message type and message structure of each communication module product may...

AI Technical Summary

Problems solved by technology

[0003] With the evolution of technology, these existing communication module products may be gradually replaced by other new communication module products, but because the message type and message structure of each communication module product may be different, it has been used in industrial The existing communication module products in the field or substation cannot be directly replaced by new communication module products

[0004] From the perspective of manufacturers of communication module products, even if old communication module products are gradually replaced by new communication module products in the market, manufacturers still have to continue to produce old communication module products to ensure that industrial sites equipped with old communication module products Or the normal operation of the substation, which may increase the production cost of the manufacturer

On the other hand, from the perspective of users of communication module products, even if old communication module products are gradually replaced by new communication module products in the market, users have to continue to purchase old communication modules already equipped in industrial sites or substations Products to ensure the normal operation of industrial sites or substations, which may also increase the user's operating costs
