Tire pressure monitoring system (TPMS) integrated with GPS tracking system is a powerful tool of fuel economy and driving safety. You don’t need to check tire pressure manually before trip – onboard display will provide you all information about tire pressure and tire temperature.

The main reasons to integrate TPMS system into your fleet management:

  • Low tire pressure increases fuel consumption and tire wear.
  • High tire pressure increases tire wear and suspension wear.
  • Driver is not able to notice tire puncture on early stage. TPMS system will inform the driver immediately.
  • Tire explosion during driving is a very dangerous event. TPMS can predict tire explotion based on internal tire temperature.
  • TMPS together with GPS tracking can prevent unauthorised tire swaps (Installation of weared tires instead of new ones).

TPMS consists of battery-powered wireless pressure sensors, driver display and optional receivers/transmitters. TPMS could be integrated with GPS tracking system via RS-232 or CAN bus interface. Some examples of compatible GPS trackers are : Galileosky, Teltonika FMB6xx, AutoGraph, SMART (Navtelecom).

 

 

Both external and internal tire pressure monitoring sensors can be used. External sensors are very easy to install but are affected by weather and road reagents. The built-in battery is designed for a two-year service life and  can be replaced. Internal sensors can be installed during the tire fitting process and are fully protected from external influences. The built-in battery for powering the internal tire pressure sensors is rated for 5 years and is not replaceable.

Information from the sensors is displayed on the driver’s monitor. While driving, the monitor continuously receives the pressure and temperature values ​​in each wheel and displays this information on the screen, as well as too-low/too high pressure alarms. Also, the received information is transmitted to the GPS tracking system using RS232 serial interface from display or CAN bus adapter. As a result, the dispatcher can remotely monitor the pressure in each of the wheels of the fleet and receive notifications when the pressure exceeds the set limits. This saves a lot of time on pre-trip tire pressure monitoring.

When installing the system on a truck-trailer combination, a repeater is added to the system. This electronic device with built-in memory and transmitter stores the identifiers of pressure sensors connected to the monitor at different times. It is necessary so that we can change trailers without additional binding of the monitor to the sensors of the trailer.

If the truck-trailer train is very long, then a transceiver can be added to the tire pressure monitoring system, acting is an intermediate repeater of the radio signal.
