Truck Trailer coupling

Simple Bluetooth Low Energy system to track record of each detachable item

What is Truck Trailer coupling?

As long as most of the trucks and agricultural (machinery) already have GPS fleet management systems, another question comes out – How to keep trailer records as well.

findy IoT Bluetooth Low energy product line deliver such a solution and is even compatible with older versions of GPS Fleet management devices and systems.

A BLE Beacon is attached to the trailer and BLE receiver is connected to the GPS fleet management device through RS232 / RS485 or 1-Wire.

Over Omnicom LLS protocol a list of BLE devices is being sent to the GPS device and from there to the Fleet management software.

Optional data is also available:

– Motion state of the BLE Transmitter could be used to identify and parir only moving objects.
– Accelerometer data of the beacon could give an information, about whether the item is in transport mode or in operational mode.
– Magnet sensor provides data or alarms for door opening.
– Temperature sensor could enable temperature logging for certain type of shipment.
