Manual
TAD data is converted to LOC data by means of a Location Rule Set. The first
kind of Rule Set is called a Location Rule Set. A Location Rule Set works by
reading in TAD data and testing it against a list of user-defined statements.
Each statement is associated with a Location. These statements are descrip-
tions of locations in terms of TAD data. For example, a basic statement, in plain
english, might read A tag is in this location if it is within 10 feet of Antenna 2 on
Cell Controller 1 and more than 20 feet from Antenna 3 on Cell Controller 1.
A very common type of Location statement is called the closest to statement.
Just like a tag can be said to be in a location because it is less than 15 feet
from a certain antenna, it can also be said to be in a location if it is closest to a
particular antenna. This can allow for a very simple definition of locations. A
basic closest to statement might read A tag is in this location if it is closest to
Antenna 2 on Cell Controller 1. Please note, a tag is assigned to the location
associated with the first statement in the list that is true.
The Location Rule Set statements can make use of a standard array of boolean
and functional operators. Without exploring the actual syntax, these statements
include and, or, not, parenthetical and closest to statements. All behave as they
would normally be expected to.
A syntax reference for Location Rule Sets is available in the ViewPoint Users
Manual.
A
LERT DATA
An Alert Rule Set is used to convert Location Data to Alert Data. The idea
behind Alert data is quite simple. When Tag location data matches certain con-
ditions, an Alert will be fired. There is no need to define conditions before
installing the system. Doing so might be counterproductive, as many of the
Alerts depend on the assets the tags themselves are attached to. But, it is
important to have a general idea about what kinds of alerts will be created. The
details of Alerts pertain to the types of Locations that should be created -- and,
by extension, on where antenna should be placed.
For reference, there are 8 Alert Types, 4 of which are Single Tag Alert Types
and 4 of which are Paired Tag Alert Types:
