  1. Remote Metering The evolution of metering from instrumentation to information

  2. 40 Years Ago • Ferraris disk meters • Manual meter reading • Pulse data loggers • PSTN modem communications • First solid-state electricity meter in 1971 • Disconnected meter model

  3. Coherent DCS Project • 21st Century data collection system • Connected data model • Unification of metering • Integrated data presentation • Real time data delivery • Extensible architecture

  4. 21st Century Data Collection System • Designed for networked infrastructure • Fully scalable architecture • Based on Microsoft .NET framework • Delivers data to SQL Server database • Browser based management interface • Real time meter displays for web pages

  5. Connected Data Model • Tree structure to represent metering structure • Data collection configured through server • Data collected every half hour • Real time meter display • Integration with manufacturers’ software

  6. Unification of Metering • Meter type independence • Manufacturer independence • Communication interface independence • Modular hardware for meter data collection • No data balkanization

  7. Integrated Data Presentation • Meter data charted on screen or printer • Reports displayed on screen or printer • Reports emailed periodically • Reports configurable by Excel spreadsheets • Building display web applications

  8. Real Time Data Delivery • Delivery of data every half hour • Real time display of selected meter • Control panel web applications

  9. System Management • User accounts and passwords • User permissions • Viewer restrictions • Meter type definition • Manual readings • Units

  10. Event Log and Alarms • All DCS events logged • Events classified as info, warning or alarm • Event log filtering • Event log aggregation • Email alarm notification

  11. Extensible Architecture • Web service interface for data access • Web service interface for system control • Meter plugins • Data conversion plugins • Report plugins • Excel spreadsheet report customisation

  12. 40 Years Hence • Evolution from information to decision • Distributed intelligence • System integration through networking • Artificial Intelligence
