The invention belongs to the technical field of industrial
automation and
informatization, and discloses a double-zone PI
database measuring point detection
system and method, and the
system comprises a first-zone
control unit, a second-zone interface unit and a second-zone PI
database which form a data production and storage chain; a second-area
heartbeat monitoring program passively reads data of a second-area PI
database to generate a first
monitoring data packet; the third-area PI database receives the
mirror image of the second-area data through a one-way isolation device; and the three-area SIS intelligent operation and
maintenance system receives the first
monitoring data packet and the
mirror image data, and carries out comparative analysis to detect an anomaly and judge a partition to which the anomaly belongs. The
system also provides a
visual user interface, displays the health state of the system, the state of the interface
machine and alarm information in the form of a dynamically refreshed statistical card, and sends an alarm notice containing a detail link when the system is abnormal. According to the invention, the automatic and visual cooperative monitoring of the double-region PI database and the
data link is realized, the fault source can be quickly positioned, and the operation and maintenance efficiency and the system reliability are greatly improved.
