Abstract

The present invention provides a system for monitoring and tracking transporting units. The system utilizes a monitoring device fitted to a transporting unit to collect data pertaining to the transporting unit and transferring the data along with a unique ID for monitoring device it to a reader device for a particular geographical area. Each reader device for a geographical area transfers data collected for a plurality of monitoring devices in its geographical area to a centralized server. The server stores the data in a database. The data server uses algorithms to calculate positions of transporting units, load managing for the reader devices, boundary crossing occurrences by a transporting unit, triggering alarm and/or locking wheels for the transporting unit when the device is out-of-range or stolen, and for searching the transporting unit. A user can view the data stored, data computed via. Algorithms and alerts are generated by the data server.
