METHOD OF INCREASING RELIABILITY OF INCOMING INFORMATION IN TECHNOLOGICAL PROCESS AUTOMATED CONTROL SYSTEM WORKING IN ARCTIC CONDITIONS Russian patent published in 2010 - IPC G05B1/00 G05B21/00 

FIELD: physics.

SUBSTANCE: information on sensors is entered into the database of a technological process automated control system (TP ACS), where said information enables determination of a list sensors whose operating capacity can be controlled through readings from the list, and separate algorithms for evaluating operation of each sensor from readings of sensors in the list are also entered into the database, from which during real time operation of TP ACS, operation of sensors is controlled from the said list and if the sensor readings do not contradict readings of sensors in the list, the readings are entered into the database for making the corresponding decision, otherwise the said data are discarded. If an alarm signal is output, special control of operation of the sensor giving out the alarm signal is carried out similarly.

EFFECT: higher accuracy of compliance with mode of exploitation of an oil and gas condensate deposit and use of TP ACS and real time detection of broken down and unstable TP ACS loops in order to prevent false data entering the TP ACS database.
