Automated Data Extraction from Legacy SCADA Interfaces
Existing SCADA screens became a reliable data source without replacing the system or waiting for an API.
- The problem
- A renewable-energy operator used proprietary supervisory control and data acquisition (SCADA) software to monitor turbines and operating conditions across multiple wind farms. Staff could reach each system only through a restricted remote-desktop screen: there was no usable API or database connection. The screen itself was therefore the only available data source, but conventional optical character recognition was unreliable because the interface rendered heavily antialiased vector text with ambiguous character edges.
- How it was engineered
- Automation navigated each remote session and captured the relevant screens. Vision models first located tables, rows, columns, labels, status graphics and value regions; difficult text was then split into individual glyphs, classified and ordered back into words and numbers before the reconstructed record was structurally validated.
