doMoov full IP convergence

doMoov / doGate, a new Smart Building architecture based on IP convergence

We need to move from BMS to SmartBuilding !

Old architectures (centralised or decentralized) are over… We embedded doMoov inside our doGate hardware and we propose distributed architecture over IP.

Less expensive : 25-40% cheaper than decentralized architecture
Good dimension : scale number of doGate depending on expected performances
Management can be done from SCADA system (use of standard routers)
Pure flexibility because network management can be done from SCADA PC
Enables gateway between any point at any place on any protocol: no need to be on the same segment or channel
One doGate can be the backup of another one
Schedule see the complete buildings not only its channel !
Full IP convergence

Architecture comparaisons and benefits

The old architecture are basically centralized architecture

That architecture is multi protocol, you can have BACnet or OPC at SCADA level but is too centralized and old. No decentralized schedule, low performance, old fashioned,

• Too centralized : if PC fails…
• low performances : only 1 acquisition engine
• Supervision and HMI are slow to start up and init
• Nothing is decentralized : everything is inside the PC
• No decentralized schedule available
• Old fashioned architecture

Second possible architecture is the full decentrailzed one: supervision and HMI are only clients of a Gateway that serves information

That is typically the architecture used by EVERY manufacturer (SBT, Honeywell, Alerton, JCI, Trane…)  but also by multi protocol gateway provides (Tridium, Loytec, Sysmik, Wago…)
That architecture is not bad but not optimized :
Too expensive : gateways cost is huge compared to standard routers
Over dimensioned : no need of so many data acquisition engines
No possibility to use a network management tool at SCADA level (or need to add a router function $$++)
SCADA only see what Gateway proposes
Time 2 engineer : need to map…

That is why we propose next architecture : distributed architecture : we are externalizing the automation only on IP. We outsource the work to pure IP automation devices

That new architecture starts to be famous in Europe for many reasons :
Less expensive : 25-40% cheaper than decentralized architecture
Good dimension : scale number of doGate depending on expected performances
Management can be done from SCADA system (use of standard routers)
Pure flexibility
Enables gateway between any point at any place on any protocol : no need to be on the same segment or channel
One doGate can be the backup of another one
Schedule see the complete buildings not only its channel !
Full IP convergence

In fact network design is very different: on architecture 1 and 2 layers are the one on the top and not dissociated

And in the doGate solution, layers are not the one on the top : they are all together and interacting via the IP convergence

That really makes the difference
