Embodiment Construction

[0026] The present invention is described in detail below by specific embodiment:

[0027] In order to adapt to the higher requirements for communication reliability and stability of the airborne cockpit display system, the present invention designs a communication hot backup system and method for active and standby dual-machines based on RapidIO bus technology. Using RapidIO switch cascading to set up the active-standby dual-machine communication hot backup system, realize the active-standby dual-computer hot backup of the communication computer through the RapidIO network, and propose a RapidIO network traversal method for the active-standby dual-computer communication hot backup system: a depth-first Adaptive dynamic recursive traversal RapidIO network method combined with sequential traversal of hierarchical switching ports.

[0028] In this method, cascaded switches are processed hierarchically according to the principle of depth first, and each level of switches is trave...

Abstract

The invention belongs to the technical field of communication and relates to a host-standby machine duplicated hot-backup system and method based on a Rapid IO bus technique. A dual-communication computer, a dual-graph production computer and a Rapid IO switchboard are in cascade connection to build the host-standby machine duplicated hot-backup system, a self-adaption dynamic recursion ergodic Rapid IO network method which combines with a grading exchange port in a depth-first mode to conduct sequential processing is designed, a host-standby machine duplicated communication hot-backup and communication route redundant function of a communication computer of a cabin displayer is achieved. A Rapid IO data communication protocol (highest rate can achieve 3.125Gbps) replaces a communication mode such as dual-opening RAM, a 429 bus and a 1394 bus to achieve stable and reliable transmission of inter-plate high speed large volume data, communication rate is improved, and communication reliability and system stability are strengthened.

Description

Technical field: [0001] The patent of the invention belongs to the technical field of communication, and relates to a dual-machine hot backup system and method. Background technique: [0002] In the field of communication technology, high reliability requires airborne equipment, such as the airborne cockpit display, which is in a very important position, and no failure is allowed. In order to ensure the reliability of equipment and systems, backup mechanisms are generally required. In traditional cockpit display systems, dual-port RAM, 429 bus, and 1394 bus are often used to realize data communication and backup between boards. A general display system includes a communication computer, a character processing computer and a video processing computer, but with the improvement of display performance requirements, the character processing computer and video processing computer are gradually replaced by a dedicated graphics generation computer, so the display system mode is comm...
