A METHOD TO INCREASE SCADA-SYSTEM RELIABILITY
Annotation
Possibilities of increasing reliability of information obtained with the use of automated monitoring and control systems in energy production industry are qnalyzed. The necessity of coupling the procedures of information input from a sensor with message encoding is justified. New principles of coding combining twopulse conditional correlation code first synthesized by the author, with a cyclic code are proposed. The proposed approach is reported to ensure a high level of reliability with the probability of non-detectable distortion in input-output data signals channel of ~10-14 which is 2-3 orders of magnitude better than the regulatory requirements. The developed method makes it possible to diagnose the fault circuit communication with the sensor, i.e., to detect a short circuit or open circuit, simultaneously with the sensor status survey.
