Network security factory-level monitoring information system

The utility model relates to a network security plant-level monitoring information system. A core server network structure of an original system adopts a single server form, and from the perspective of a system security theory, once a core server is paralyzed or halted, a monitoring information system of a whole plant loses monitoring. The utility model discloses a network security plant-level monitoring information system. The device comprises a base, disk array (1), the disk array is respectively connected with a real-time data server A (2) and a real-time data server B (3); the real-time data server A and the real-time data server B are respectively connected with the aggregation switch (4); wherein the convergence switch is respectively connected with the interface machine (5), the mirror image isolator (6), the first-stage coal consumption switch (7) and the second-stage SIS switch (8), the mirror image isolator is connected with the MIS switch (9), and the second-stage SIS switchis connected with the se
