Main-standby independent redundant network architecture of coal mine safety monitoring system

Abstract

The invention discloses a main-standby independent redundant network architecture of a coal mine safety monitoring system. The network architecture comprises a mine net, a main external network switch, a main network gateway, a main mine looped network switch, a main province uploader, a main office uploader, a main mine server, a main WEB publisher, a main mine monitor, a main looped network monitor, a standby external network switch, a standby network gateway, a standby mine looped network switch, a standby province uploader, a standby office uploader, a standby mine server, a standby WEB publisher, a standby mine monitor and a standby looped network monitor. The mine network is connected with the main external network switch and the standby external network switch; the main external network switch is connected with the main mine looped network switch through the main network gateway; and the standby external network switch is connected with the standby mine looped network switch through the standby network gateway. The network architecture has the characteristics that the network architecture is simplified, and the fault points are reduced, so that the normal operation of the monitoring system is guaranteed, and the uploading interruption caused by equipment reasons is avoided.

Description

technical field [0001] The invention relates to a coal mine safety monitoring system with active and standby independent redundant network architecture, especially a coal mine with simplified network architecture and reduced failure points, thereby ensuring the normal operation of the monitoring system and eliminating the interruption of uploading due to equipment reasons The security monitoring system has an active and standby independent redundant network architecture. Background technique [0002] The ring network system composed of the central station of the coal mine safety monitoring system consists of an underground ring network switch to form the underground ring network of the monitoring system. The mine system is connected to the underground ring network switch through a Cisco switch to form a mine system network. The god gatekeeper realizes the isolation of internal and external networks. [0003] The mine monitoring host is not directly connected to the undergro...

AI Technical Summary

Problems solved by technology

[0003] The mine monitoring host is not directly connected to the underground ring network system, resulting in a complex network structure of the mine system. At the same time, there is only one underground ring network switch in the central station, and the redundancy is not enough. When the ring network switch fails, the monitoring system will be damaged. The whole network is interrupted

[0004] There is only one network isolation device, which is also the weak link of the upload system. No matter how many external network cables come from the information center for backup, only one can be used at the same time, and it is impossible to realize dual-channel real-time backup and automatic switching
