Dual-machine backup redundant control system

Abstract

The invention discloses a dual-machine backup redundant control system, comprising: a dual redundant hot standby device and an IO port dual redundant device, wherein the dual redundant hot standby device comprises: an upper computer active and standby state setting module, a lower computer active and standby state setting module and a channel selection module; the upper computer active and standbystate setting module is used to determine a current duty upper computer; the lower computer active and standby state setting module is used to determine a current duty lower computer; the channel selection module is used to send the network data from the current duty upper computer to the lower computer or the external network; and the IO port dual redundant device is connected to the upper computer active and standby state control module, and used for outputting the video data of the current upper computer. The dual-machine backup redundant control system solves the problem of data hot backup of network nodes of the combat system applicable to the upper-lower frame architecture, fully considers the architecture and high reliability requirements of the combat system, and can dynamically adjust the configuration according to the actual deployment environment of the network of the combat system, having good flexibility and scalability.

Description

technical field [0001] The invention relates to the technical fields of computer network and electronic information, in particular to a dual-machine backup redundant control system. Background technique [0002] Adopting the upper-lower computer architecture is an important measure to improve the system performance of the current combat system network nodes 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 operation experience. The lower computer connects to the external combat network and is assigned a unique fixed IP address, responsible for data collection, calculation, analysis, and generating results. For transactional work, the processing data volume is large, the frequency is high, and the real-time requirements are strong. The upper computer and the lower computer are connected by a network data exchange module to ...

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
