DRAFT TrimTrac 1.5 Technical Manual v0.3ab 8
Enhanced Functional Capabilities
Position reporting triggered by motion continues to be an important attribute of
the TrimTrac 1.5; however, a range of powerful new functional enhancements
now augments this basic capability. The TrimTrac 1.5 is backwards compatible
with applications developed for the first generation TrimTrac.
On-board Geofencing
The TrimTrac 1.5 can self-monitor up to two geofences. These geofences can be
either rectangular or circular with reporting based upon whether the device is
inside or outside the geofence area or when it has simply crossed the geofence
boundary. Geofences can be established either during initial activation of the
device, established on-the-fly via over-the-air commands or upon operation of a
local switch connected to the TrimTrac 1.5 input module. These capabilities
allow the device to be “locked down” where needed without creating nuisance
reports during normal operation. (See AT+CTKK on page 89;
SET_GEOFENCE_CONFIG on page 117)
Scheduled Hours of Operation
The feature is particularly useful in the monitoring of commercial assets that are
used during certain hours of the day, but then are supposed to remain at rest
during the after hours.
The Schedule Hours of Operation feature is used to establish how the device will
operate during daily hours of normal operation. During normal hours of
operation, position reports may not be needed unless, for instance, a geofence has
been violated. Outside normal hours of operation, however, any motion of an
asset may be considered “unauthorized” and it would be desirable for the
TrimTrac 1.5 to report this motion and its current position. Monitoring of
equipment at a construction site is an application example that would use this
Schedule Hours of Operation feature, possibly in conjunction with a geofence.
(See AT+CTKZ on page 99; SET_EXT2_APP_CONFIG on page 116)
Runtime Meters (2)
Equipment maintenance schedules are often managed based upon accumulated
run-time hours. The TrimTrac 1.5 offers two resetable runtime meters: one is
triggered by motion and, if a plug-in module is used, the other can be hardwired
to contacts on a sensor, such as an oil pressure switch. (See AT+CTKZ on page
99; SET_EXT2_APP_CONFIG on page 116)
