BACKUP SOFTWARE-HADWARE SYSTEM FOR AUTOMATIC MONITORING AND CONTROL

摘要

FIELD: information technology. ^ SUBSTANCE: in the software-hardware system for controlling technological processes, automation processors are connected to an EN system bus which is based on the Industrial Ethernet interface in form of a ring structure of series-connected network switches, over two channels; the automation processors are connected to input/output stations having an interface module and modules for communication with the technological process; the automation processors are connected to the interface modules of the input/output stations over an ENL bus which is based on Industrial Ethernet with a radial connection topology and ensuring the minimum possible data exchange time for the Industrial Ethernet; the interface module of the input/output station is connected to each module for communication with the technological process over a separate serial interface of the input/output bus; automation processors also have channels for connecting to ENS buses based on Industrial Ethernet on a ring connection topology for constructing multiply backed-up systems. ^ EFFECT: high reliability of the system bus, high rate of collecting technological process data and high fault-tolerance. ^ 5 cl, 5 dwg
