TPMS designed for drop-and-hook fleets

Advantage PressurePro, maker of the original external Tire Pressure Monitoring System (TPMS), announced the release of its new Intelligent “Drop-and-Hook” TPMS. The Drop-and-Hook system has been designed to work specifically with multi-trailer fleets, allowing automatic tethering and un-tethering of trailers to tractors.

The Intelligent Drop-and-Hook System is comprised of an Intelligent Monitor (IM), Intelligent Repeater (IR), and sensors. The IM is mounted in cab and displays current pressures and alerts to a driver, or can be integrated with other telematics products in the vehicle to report pressures and alerts to an office/remote management system. Capable of reading 16 tires each on a tractor and up to three trailers, the IM has a 64 tire reading potential. The IM can communicate with other devices in the tractor via RS232, J1708, or J1939 networks.

The IR is installed directly onto a trailer and hooks into the trailer's power (ABS) line, allowing communication of the trailer's sensors with the IM (or Bridge) in the tractor. When the tractor and trailer are tethered, the Monitor in the tractor picks up the IDs, pressures, and positions of sensors on the trailer from the IR. 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. When a new trailer is introduced, the monitor recognizes the new IR and accepts its full information.
