Patent Images
1. An RF tracking system comprising:
- a tracking device comprising a battery, a GPS positioning element, a two-way communication module, and memory;
a route exception database comprising a plurality of exception event locations; and
a receiver device;
the tracking device configured to send data regarding the location of the tracking device to the receiver device, and the receiver device configured to receive the data from the tracking device;
wherein the tracking device is configured to modify a ping rate and a ping period at which the data is sent by the tracking device based on a distance between the location of the tracking device and an exception event location from the database.

Abstract
Asset tracking system that utilizes a time-based ping in which the ping rate and the ping period are based on a predetermined event. Over the period of use of the system and device, the ping rate and ping period are adjusted based on the expected occurrence of an event. The system has lower operational cost, particularly battery maintenance cost, than conventional active ping systems that have a set ping rate or a random ping rate.

9. A method of tracking an asset with a tracking device operably attached thereto, the tracking device having a positioning unit and a central processing unit (CPU), the method comprising:
-
setting an initial ping rate of the tracking device; determining a location of the tracking device via the positioning unit; checking a route exception database for an exception event within a predetermined distance of the location via the CPU; increasing the initial ping rate via the CPU to a new ping rate if the exception event is within the predetermined distance of the location; and transmitting a plurality of pings from the tracking device at the new ping rate. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
