A dual-computer 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 double-redundant device; the dual-redundant hot-standby device includes: The state setting module and the channel selection module; the main and standby state setting module of the upper computer is used to determine the upper computer on duty; the main and standby state setting module of the lower computer is used to determine the lower computer on duty; the channel selection module is used to select the The network data is sent to the lower computer or external network; the IO port dual redundancy device is connected to the main and standby state control module of the upper computer to output the video data of the current on-duty upper computer. It solves the data hot backup problem of combat system network nodes suitable for upper-lower computer architecture, fully considers the system architecture and high reliability requirements of the combat system, and can dynamically configure and adjust according to the actual network deployment environment of the combat system. Has 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
