Abstract
An asset tracker for detecting an end of trip by an asset tracker are described. An end of trip may be detected using a Global Navigation Satellite System (GNSS) module or an Inertial Measurement Unit (IMU), such as a three-axis accelerometer. In some implementations, the asset tracker uses the IMU for end of trip detection. In other implementations, the asset tracker uses the IMU for impact detection while using the GNSS module for end of trip detection.
Claims20
An asset tracker, comprising:
- a housing;
- a controller disposed in the housing;
- a location module disposed in the housing and coupled to the controller;
- a 3-axis accelerometer disposed in the housing and coupled to the controller;
- and
- a memory coupled to the controller, the memory storing machine-executable programming instructions which, when executed by the controller, configure the asset tracker to:
- operate the asset tracker in a shipping state in which a first location of the asset tracker is obtained by the location module;
- in response to an activation successful event, transition the asset tracker to a travel motion detection state;
- and
- in response to detecting travel motion by the 3-axis accelerometer, transition the asset tracker to a traveling state.

A method for trip detection by an asset tracker, the method comprising:
- operating the asset tracker in a shipping state including obtaining a first location of the asset tracker;
- in response to an activation successful event, transitioning the asset tracker to a travel motion detection state;
- and
- in response to detecting travel motion, transitioning the asset tracker to a traveling state.
