AUTOMATED PROCESS CONTROL SYSTEM Russian patent published in 2021 - IPC G05B19/00 G08B21/00 

FIELD: automated process control systems.

SUBSTANCE: invention relates to an automated process control system. The system contains a measuring unit, consisting of basic modules that receive information from a set of corresponding basic sensors, functionally connected to the controlled equipment, and send the processed information using the lower-level software to the monitoring unit, consisting of diagnostic controllers - the main processors that process the information received from the corresponding modules of the measuring unit for performing, using the upper-level software, calculating diagnostic features, assessing the technical condition, diagnostic analysis of various combinations of controlled equipment and its compliance with the technological process embedded in the control unit of the integrating and analyzing the information received from the processors of the monitoring unit, and also capable of generating control signals for adjusting the technological process within the limits of the permissible parameters laid down in it, while any of the processors is capable of generating instructions for technical personnel when data is output from the required parameters using an expert module with a set of rules and generating a signal for manual control points through the processing unit and network distributed architecture for visual display, which provides the generation of graphical representations of the monitored parameters at the diagnostic station of the system, their derived values ​​and diagnostic features, while the system is additionally equipped with at least one power distributor equipped with uninterruptible power supplies and/or generators of direct and/or alternating current for electric power supply from the electrical network of the system elements, and the power distributor is made with the possibility of automatic switching on uninterruptible power supply elements and / or starting up current generators when the power supply is disconnected from the network, and the main measuring unit, the monitoring unit are equipped with redundant sensors, measurement modules and processors, respectively, to monitor the performance of working sensors, measurement modules and processors during periodic switching to redundant elements, while the control unit is configured to compare the readings of operating and redundant sensors, modules after switching to redundant elements and processors for compliance with each other within the permissible error of these elements, and also with the possibility of evaluating the measurements of other sensors, modules and processors technologically related to these data, which have been tested by switching, and, in case of their discrepancy with the measurements of working sensors, modules and processors, disconnecting the working sensors, modules and processors, with the inclusion in operation redundant sensors, modules and processors.

EFFECT: increasing the reliability of the process control system.
