Recording Data
At set intervals the TRACKER software sends out a request to each Beacon, asking for its stored list of Tag IDs. After a successful transmit Beacons then have their list cleared and begin to collect the next list of tags.
The time between polling is set within software, it may be anywhere between 3 and 60 seconds, depending on system configuration. Beacons that see a lot of activity require a faster refresh, where as low activity beacons need not have their lists cleared so often.
Tag IDs are stored in the TRACKER database, recording which beacons the tags have passed, and at what time. The TRACKER software keeps a continually updated record of tags logged in and out of the system.
The ODBC compliant TRACKER database allows it to share data with other applications. For example, a future generation of PED Software may be able to send a message to all personnel between Beacons 5 and 8 by drawing this data from the TRACKER database, or management tools could draw real time locations of vehicles and personnel.
Much of the system configuration is handled within software, reducing costs and time involved with both initial set up, and changes/additions to the system. The ease of adding and moving beacons in the system simplifies future expansion.
