Problems solved by technology

[0003] Most of the current ring network gateways have the following deficiencies: first, the signal suppression ability is not strong, and some have a certain signal suppression ability, but not very strong; second, the performance is poor, the data packet loss is serious, and the communication is restored. Too much delay

Abstract

The invention discloses an annular network gateway which comprises an outer protection module, a power supply managing control circuit, a protocol expansion module, a protocol conversion module, an in-network communication module, a physical layer protocol supporting module, a protocol control module, a core control module, an input module, a storage module and the like. The annular network gateway is designed by specially aiming at an industrial automation and intelligent environment and under the industrial intelligent environment, the annular network gateway has a signal suppressing capability. A redundancy information transmission module does not exist. Under the condition of hard link failures (N-1), a safety mechanism can ensure that packages will not be lost and the communication recovery delayed time is zero. The management memory space is large and management and maintenance are intelligent.

Description

technical field [0001] The invention relates to a communication network device, in particular to a ring network gateway. Background technique [0002] With the rapid development of the power industry, the use of power electronics technology to adjust and control the main parameters of the power system to improve the controllability, effectiveness and reliability of the power system is the "AC flexible transmission system", that is, the flexible AC transmission system. (FlexibleACTransmissionSystems, FACTS) technology has been widely concerned, researched and applied. [0003] Most of the current ring network gateways have the following deficiencies: first, the signal suppression ability is not strong, and some have a certain signal suppression ability, but not very strong; second, the performance is poor, the data packet loss is serious, and the communication is restored. The delay is too high. Contents of the invention [0004] The purpose of the present invention is to...
