  1. Loosely coupled OPC client used to animate GIS Mariusz Postół Maciej Zbrzezny www.cas.eu

  2. CONTROL PROCESS • Łódź citizens #: 1M • Heating plants: 3 • Total thermal output: 2560MW • Heat distribution network:~800km ~500miles • Number of nodes: ~7 000 • Production in cogeneration: • Hot water • Electric power • Steam

  3. GIS – Functions: Inventory & localization Topology map Inventory Modeling Hydraulic calculation Supply area visualization More.... NOT REAL-TIME SYSTEM

  4. Application – general model Presentation Business Data APPLICATION

  5. Application: integrated architecture Presentation services 3 layers Business services Data services

  6. Application: distributed architecture Presentation services 3 layers Business services Data services

  7. Application: communication standards SQL OPC HTTP/XML SQL OPC HTTP/XML Presentation services 3 layers Business services Data services

  8. GIS: Process integration • Multisource • Connect/Disconnect/reconnect • Items database • Group management • Subscription • Read (synch/asynch/deadband) • Write ??? • Security • Shutdown • To do it we need: • To know OPC specification • To write a lot of lines of code (XX 000) • To develop for the same platform • To know internal architecture & interfaces specifications GIS BLACKBOX Presentation GIS CACHE Business OPC SERVER PROCESS INTRFC OPC INTRFC Data(OPC/C)

  9. GIS: Process integration CACHE SERIAL OPC/S IMPORT IMPORT Presentation GIS Business OPCT Data HTTP/XML DATA

  12. OPCT FEATURES OPCT THERE IS NO NEED TO MAKE THE GIS CLIENT SO COMPLICATED HTTP/SOAP/WSDL • Multi-sources; • Easy configurable; • Advanced transport algorithm: deadbands and minimal update rates; • Transactions; • Buffered queues;

  13. HTTP / SOAP / WSDL • Easy to access well defined interface: • WSDL description: http://Server:9000/OPCRealtimeDataAccess?wsdl • UML Description • Available services: • OPCRealtimeDataAccess • OPCBufferedDataAccess

  14. OPCRealtimeDataAccess Service for accessing current data. • Values • Items list • List of available properties and value of properties

  15. OPCBufferedDataAccess • Protection from missing any information • FIFO queue algorithm • Transaction algorithm • connect to queue; • start transaction; • get elements; • end transaction • remove queue contents
