The implementation of medical asset management is similar to that
of infant abduction prevention. The difference is that RFID tags are
attached to assets. Both infant security tags and RFID tags have 433
MHz and 125 kHz radio modules. Similar to the infant abduction prevention
system, the medical asset management system locates assets by identifying
locations of exit monitors.
- RFID tags are attached to medical assets to uniquely identify them.
- When assets approach exit monitors at entrances/exits, 125 kHz
radio modules of RFID tags receive Beacon frames sent by the exit
monitors.
- Through 433 MHz radio modules, the RFID tags send RFID tag IDs
and received exit monitor information to RFID receivers.
- The RFID receivers then forward the received information to the
medical asset management system through APs and upstream Ethernet
links.
- The medical asset management system matches the received information
such as exit monitor IDs with the preset location information about
the exit monitors, and then identifies asset locations. This system
enables regional location of assets and real-time monitoring of asset
locations.
