Advantage PressurePro says it designed its Intelligent Drop-and-Hook Tire Pressure Monitoring System to work with multi-trailer fleets, allowing automatic tethering and untethering of trailers to tractors. The system is comprised of a monitor, repeater and sensors.
The monitor is mounted in-cab and displays current pressures and alerts to a driver, or it can be integrated with other telematics products in the vehicle to report pressures and alerts to an office or remote management system. Capable of reading 16 tires each on a tractor and up to three trailers, the monitor boasts a 64-tire-reading potential, according to the company. The monitor can communicate with other devices in the tractor via RS232, J1708 or J1939 networks.
The repeater is installed directly onto a trailer and hooks into the trailer’s ABS power line, allowing communication of the trailer’s sensors with the monitor in the tractor. When the tractor and trailer are tethered, the monitor in the tractor picks up the IDs, pressures and positions of the sensors on the trailer from the repeater. When a trailer is unhooked and there is no communication for 20 seconds, the monitor “forgets” that trailer and begins to look for new readings, the company says; when a new trailer is introduced, the monitor recognizes the new repeater and accepts its full information.
