Olika typer av lokaliserings tjänster

RTLS vs. Conventional RFID


Passive RFID
-

Short Read Range Identification Technology


Chokepoint
-
based


More data than barcode, easily readable, becoming
inexpensive


Standardized (EPC Global )


Primarily an identification resource


not for location tracking.


Active RFID
-

Location Tracking


Point Solutions


Use portals/scanners as overlays to existing LAN/WLAN


No standards proprietary networks


Various frequencies, tags & vendors create incompatible silos


Varying levels of performance, scalability and accuracy

“Where is it”


Equipment Locator


Allows a worker (Nurse) to locate the nearest piece of
equipment of a certain type.


Equipment must be location tagged with use status
monitored


Nurse’s location is tracked as well


Nurse interacts with the system on any phone using an
IVR system.


Speech recognition allows question to be asked in any
number of ways using natural language

Where is an IV
pump?

The nearest IV
pump is in the
east hallway
outside room 301

Alarm Manager

WLAN

Access Point

1.

Patient Monitor
detects an out of
bounds condition

2.

An alarm is
triggered

3.

Patient Monitor sends
alarm message to Alarm
Manager

4.

Alarm Manager determines
distribution of alarm. Sends alarm to
attending nurse’s WLAN handset

5.

Attending Nurse’s WLAN
handset rings and a text
message is displayed indicating
problem and monitor the alarm
was sent from. Nurse is busy
and does not accept the alarm

6.

After a preset time the
alarm rings the charge
nurse’s WLAN handset.
Alarm accepted.
