2.2 System structure
The nurse call system uses a bus system which comprises a group bus OSYnet
and a room bus RAN. The group bus OSYnet links the individual rooms and potential
interfaces in the ward. The room bus RAN links the equipment and
devices in the rooms themselves.
The respective room terminal controls the room bus RAN and forms the
connection between room bus RAN and group bus OSYnet: ComTerminal Flamenco,
RoomTerminal Flamenco, ControlTerminal Flamenco, ControlTerminal
with doorplate Flamenco.
System control is realised in the OSY-ControlCenter which controls the data
flow as well as all speech communication.
If the OSY-ControlCenter should fail or break down, decentralised OSYnet-
SafetyControllers can takeover the control of the basic nurse call functions.
These controllers are fitted to ward's OSYnet group bus.
Decentralised power supply units provide the electric power for the system.
Number of units and their location depend on the specific demand for electric
power. Power for the OSY-ControlCenter is also provided via an external power
supply unit.
