In chemical reaction processes that are potentially hazardous, this system contributes to safety by predicting abnormal signs of process reactions, and notifying the trend in advance in a trend graph.
Introduction of the Early Warning System for Times Series Data
A software system that predicts the future course of critical process variables and constantly monitors them to make sure they have not deviated from control values.
The Early Warning System for time series data provides easy automatic monitoring of critical process variables, predicts future fluctuations, and visualizes predicted future fluctuations in a trend graph. If the system predicts that future fluctuation will reach a critical control value (a value at which a protective device is activated, a value set as a design limit, etc.), it issues a predictive alarm to make the operator aware of the situation.
The Early Warning System also helps operators to respond appropriately well in advance by displaying predicted future trends and time of occurrence.
Early warning system for time series data is a DCS independent software application that uses the OPC-DA communication protocol, contributing to enhanced safety monitoring at all manufacturing sites.
The Early Warning System is a software application that is independent of the DCS. At a site where DCS alarm management is not in place and DCS alarms are frequently issued, it is sure to provide the operator and other staff in the control room with the desired level of awareness.
The Early Warning System automatically collects data on the monitored variables and predicts the future course of single variable data based only on that data using the Azbil’s logic.
Early warning system for time series data detects the predicted tendency of important process variables to reach critical control values and automatically displays the situation on a large display, providing reliable notification even when the DCS is full of alarms during interlocks and shutdowns.
With its automatic display function and large display, the Early Warning System helps every staff member in the control room solve problems through teamwork.
