Invitation Letter and Agenda :

Discussed Use Cases :

• Use Case with a SCADA System for the Climate Control
  • Application Outputs setpoint (commands) for each fane coil, curtain , blinder, lights
  • Application Inputs temperature sensors (inside / outside), humidity (inside / outside), COV, CO2, light sensors (inside / outside), switches, solar radiation
  • Application 1 : Management of the luminosity in a room : Open the curtain if light outside is high enough or switch on the light inside, switch off the light and close de curtain when we want to decresase luminosoty in a room. based on a real switch.
  • Application 2 : If the solar radiation is high enough to increase temperature in a room we open the curtain to solar radiation (fan coil consume less energy)
  • Application 3 : If the solar radiation is high, to decrease temperature in a room we close the curtain/Blinder to solar radiation (fan coil consume less energy)
  • Application 4 : switches in a room allow to switch on/off the lights
  • Application 5 : termostats in room allow to drive fan coils .

• Conflict App1 / App3
  • conflict : luminosity in room (App1) versus cool the room (App3)

• Strategy 1 :
  • knowing the application he give a priority
  • If people are in a building, priority to luminosity in the other case priority to curtain / blinder are at the middle stage

• Conflict App4 / App4

• Strategy :
  • automaton on/off is on
  • adding some time delay consideration

COMMENTS :

• Sometimes we need to have informations on the semantic off the App (energy consumption is a priority over luminosity)
• Sometimes we need more inputs than those we want to manage for actuation conflict (when Paul is in the room then …)

• Same applications based on multiple devices and Man machine interfaces
