A760 People/Event Correlation Process
The A760 Proximity Locator works in conjunction with A750 Room Locators and R142 Staff Badge tags.
A750 Room Locators are positioned to cover specific areas, such as rooms, closets or entire floors. The IR-
enabled R142 tags can report specific location data when it transmits its RF location payload to an RF
Code reader. As a person moves from one room to another, their badge tag will transmit the location code
it detected from the last seen A750. Each A750 Room Locator is assigned a unique ID for distinct room
locations. A760 Proximity Locators are also assigned ID’s which allow for people and event tracking with
sub-room level accuracy. For example, if a supply cabinet door is instrumented with a reed switch
connected to an A760, door open events can be correlated with a wearer of an R142 Staff Badge. The
communication between the solution components is as follows:
1.
Battery-powered wall unit detects event (wired dry contact or reed switch connected to door or
other device).
2.
Wall unit and badge tag communicate (send/receive) via low power 915 MHz broadcasts. Wall unit
determines closest badge tag if multiple badge tags are within close proximity.
3.
Badge tag transmits via 433 MHz RF, broadcasting its unique tag ID, room location, and event
payload to the RF Code reader infrastructure.
4.
The wall unit also has a unique ID and signals events via 433 MHz RF to the existing RF Code
reader infrastructure.
5.
Time stamps, payloads and IDs from the wall unit and badge tag transmissions are correlated via
software to accurately tell you who did what, when, and where.
