1.0 SYSTEM OVERVIEW
1.1 SYSTEM COMPONENTS
The Wireless Gateway Receiver forms the "brain" of the
SmarTire
™
platform. The receiver captures data transmissions
from tire sensors mounted on each wheel which is then analyzed
against programmed user-defined settings and, if it determines
that a tire is under-inflated or running over temperature, an alert is
triggered. Robust and weatherproof in design, the Wireless
Gateway Receiver can be conveniently mounted directly to the
vehicle's chassis. It also interfaces with the vehicle's J1939
network for seamless integration.
Real-time tire pressure and temperature information is available to
the driver on demand via the SmarTire
™
display. If the system
detects a tire that is under-inflated or overly hot, the display will
alert the driver to the condition before it becomes dangerous.
Industrially designed for the harsh environment of a commercial
truck tire, the tire sensor measures internal tire pressure and
temperature every 12 seconds and transmits data every three to
five minutes. If the system detects a pressure change of 3 PSI
(0.206 bar) or greater, it breaks its regular schedule and transmits
data immediately. Each tire sensor is mounted in a break away
cradle so that in the event of in-field damage, the sensor remains
unbroken.
Tire sensors are mounted to the surface of the rim using a
stainless steel strap. Installed by Bendix on hundreds of
thousands of wheels world wide, strap mounting is the most
reliable and universal method of sensor installation available.
Wireless signals from tires on the front axle are captured by the
wireless gateway directly. Signals from the rear axles and the
trailer are captured by an antenna mounted at the rear of the
vehicle. An external antenna ensures signal reception reliability so
that SmarTire
™
TPMS always has up-to-date tire status
information accessible at the push of a button.
When a tire problem occurs on a towed trailer, the trailer lamp will
clearly indicate it to the driver. The lamp illuminates at the first
sign of trouble, as well as flashes to indicate the type of problem
found.
