Dual-redundancy hot backup device

Abstract

The invention discloses a dual-redundancy hot backup device. The device comprises an upper computer host and backup state setting module, a lower computer host and backup state setting module, a databroadcasting module and a channel selection module; each of the upper computer host and backup state setting module and the lower computer host and backup state setting module comprises a network controller module, a channel signal acquisition module and a channel calculation logic module; the channel calculation logic modules are connected with the network controller modules and the channel signal acquisition modules; the data broadcasting module is connected with the network controller modules; and the channel selection module is connected with the channel calculation logic modules and the data broadcasting module. The device solves the problem of data hot backup of network nodes of a combat system suitable for upper-lower computer architectures, fully considers a system architecture anda high-reliability requirement of the combat system, can perform dynamic configuration adjustment according to an actual network deployment environment of the combat system, and has high flexibilityand expansibility.

Description

Technical field [0001] The invention relates to the technical field of computer networks and electronic information, in particular to a dual redundant hot backup device. Background technique [0002] The use of the upper-lower computer architecture is an important measure for the current combat system network nodes to improve system performance and increase the overall computing performance of a single node. In this architecture, the upper computer generally only deploys human-computer interaction software to provide users with a smooth software running experience. The lower computer is connected to the external combat network and is assigned a unique fixed IP address, responsible for data collection, calculation, analysis, and result generation. Transactional work, large amount of processing data, high frequency, and strong real-time requirements. The upper computer and the lower computer are connected by a network data exchange module to form an internal network of nodes. The ...

AI Technical Summary

Problems solved by technology

The lower computer of the combat system network node is directly connected to the combat network, and is assigned a unique network IP address. Its working status is jointly driven by the combat network and the user operation command input of the upper computer. Because the Ethernet has non-repeatable mandatory requirements for the IP addresses of Internet access devices , or when the combat system adopts network security management measures based on the whitelist of network IP addresses and needs to detect the validity of the IP addresses of Internet nodes in real time, the above two invention patents are not applicable to the lower-level network nodes of the combat system with the upper-lower computer architecture. Machine redundancy design

[0004] In addition, the network node of the combat system is the carrier for deploying combat application software, which determines that the upper computer plays the role of the receiver of user operation instructions and acts as a bridge between the user and the lower computer. With the continuous increase of the functions of the combat application software, the upper computer Therefore, the reliability of the upper computer also restricts the overall availability of a single network node. Since the upper computer belongs to the internal network of the node, it has its own input and output ports and the node requires a unique input and output port as a whole. The above-mentioned invention patents are also not applicable to the redundancy design of the upper computer of the combat system network node
