The most important benefit is the
improvement in safety. The remote
monitoring of tyre temperature and
pressure means that mine operators
are alerted to all temperature and
pressure hazards with tyres before
they can develop into potentially
harmful incidents. It also reduces the
time that personnel are required to
interact with large mobile equipment
to check pressures. It puts mine
operators and personnel in control of
their tyres from behind the safety of a
computer screen.
Kal Tire offers the following three
distinct TTT product lines to cater for
all markets.
TTT In-Cab
This is the new entry level model: a
stand-alone unit that uses an in-cab
display (ICD) to inform the driver of
any issues. It includes:
n
n
An in-cab 7 in. LCD touch screen
showing pressure and temperature
data.
n
n
Internal data storage, downloadable
via WiFi connection.
n
n
Temperature and pressure data
viewable on the Kal Tire Graphing
App.
n
n
All alarms given to driver.
TTT Online
This is the new internet‑based system
that transfers data to the Kal Tire servers
via a GPRS cellular network or a
2.4 GHz WiFi network. This uses an
in-cab display (ICD) to inform the driver
of any issues, as well as having the data
viewable on the TTT Console and email
alerts. It includes:
n
n
A 7 in. LCD touch screen displaying
pressure and temperature data
in-cab.
n
n
Near real-time data transfer via the
mineʼs 2.4 WiFi network or via local
GPRS cellular data network.
n
n
Detailed GPS data uploaded to
the TTT console and stored on the
device.
n
n
Near real-time tyre data uploaded to
the TTT console.
n
n
Email alerts.
n
n
All alarms given to the driver.
TTT Network is the industry
established closed mesh network based
system, which transfers data to the
Kal Tire servers via a custom base
station. It uses the base station to present
the data and inform the local operator of
any issues, as well as having the data
viewable on the TTT console. It runs on
an independent wireless network, using
solar-powered repeater stations. This
gives a standalone solution that is
suitable for any surface mine site. A
high-range frequency is used with 26
switching channels to ensure the
connection is stable and reliable. The
system automatically connects to a free
channel if communications become
interrupted. This setup ensures that even
during internet blackouts the vehicles
are being remotely monitored constantly
and changes in a tyreʼs condition can be
acted upon swiftly. It includes:
n
n
Near real-time data transfer via
the Kal Tire TTT 900 MHz repeater
network or the mineʼs 2.4/5 GHz
WiFi network.
n
n
Near real-time tyre data uploaded to
the TTT console.
n
n
Email alerts.
n
n
Remote near real-time vehicle
monitoring without the need for
internet access.
TTT Network is installed on many
mine sites globally. It directly monitors
the chamber temperature and pressure
of a tyre through an internally mounted
sensor. The sensor data is transmitted to
the vehicle MCM (master control
module) via a 434 MHz signal. The
Kal Tire's distinctive golf ball-size sensor installed in a tyre.
