Embodiment Construction

[0020] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0021] System embodiment:

[0022] The present invention provides a FC-AE-ASM parallel redundant system. The parallel redundant system includes a redundant control module and at least two redundant channels. This embodiment uses two redundant channels as an example to illustrate the parallel redundant system. For the structure of the redundant system, if three or more redundant channels are set, the structural connection relationship is similar to that of two redundant channels.

[0023] Such as figure 1 As shown, the two redundant channels are A channel and B channel respectively, wherein, the A channel includes the data receiving module, the primitive detection module, the link synchronization module and the A port state machine, and the B channel includes the data receiving module, the primitive detection module Module, link synchronization m...

Abstract

The invention provides an FC-AE-ASM parallel redundancy system and data processing method thereof. A redundant control module detects whether the state of each port state machine in the redundant channel is an activated state or not in real time; if in an activated state, the redundancy control module controls and selects a channel of the port state machine to receive data; according to the methoddisclosed by the invention, only the activation state of the port state machine in each redundant channel needs to be detected, and data frames in each redundant channel do not need to be compared orsubjected to redundancy search, so that the redundancy processing difficulty of receiving parallel data is simplified, the data processing time delay is reduced, and the FC-AE-ASM parallel redundantdata processing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of data processing, in particular to an FC-AE-ASM parallel redundant system and a data processing method thereof. Background technique [0002] Fiber Channel (FC) is a high-speed serial transmission protocol, which has formed a huge network protocol cluster and has become the main candidate protocol for avionics unified network. Fiber Channel Avionics Environment (FC-AE) is a special enhancement system for avionics based on Fiber Channel. FC-AE-ASM (Anonymous Subscriber Messaging, ASM) protocol, as an upper-layer protocol of FC network defined in FC-AE subset, has the necessary features to implement the upper-layer protocol in FC network, and can indicate two ports in the application of avionics system communication between. The FC-AE-ASM network is high-speed, deterministic, secure, and low-latency, making it ideal for data communication between processors, sensors, and displays in an avionics environment...
