Container tracking
First Claim
1. A container tracking system comprising a mobile unit configured to be coupled to a container to be tracked and to communicate with a ground control unit through a communication system;
- the mobile unit comprising positioning means, alarm means adapted to detect alarm conditions related to said container, and communication means adapted to generate a tracking signal containing position data of said mobile unit and, if present, alarm information associated with one or more alarm conditions related to said container;
said mobile unit being configured to evolve to a low activity state whenever a communication unavailability condition of said tracking signal through said communication system occurs;
said low activity state providing for switching off said positioning means and said communication means of said mobile unit;
wherein said mobile unit is configured to remain in said low activity state for a predetermined wake-up time interval and is adapted to pass to an activation state, at the end of said wake-up time interval;
wherein said mobile unit is configured so as to switch from said activation state to a coverage detection state in which said mobile unit checks the communication availability or unavailability of the tracking signal through said communication system.

Abstract
A container tracking system comprising a mobile unit configured to be coupled to a container to be tracked and to communicate with a remote control unit through of a communication system. The mobile unit comprising a positioning module, an alarm module adapted to detect alarm conditions related to said container, and a communication module generating a tracking signal containing positioning data of the mobile unit and/or alarm information associated with one or more alarm conditions related to the container. Furthermore, the mobile unit is configured to evolve to a temporary deactivation state whenever a communication unavailability condition of the tracking signal through the communication system occurs.

13. A container tracking system comprising a mobile unit configured to be coupled to a container to be tracked and to communicate with a ground control unit through a communication system;
- the mobile unit comprising positioning means, alarm means adapted to detect alarm conditions related to said container, and communication means adapted to generate a tracking signal containing position data of said mobile unit and, if present, alarm information associated with one or more alarm conditions related to said container;
said mobile unit being configured to evolve to a low activity state whenever a communication unavailability condition of said tracking signal through said communication system occurs;
said low activity state providing for switching off said positioning means and said communication means of said mobile unit, wherein said mobile unit is provided with an arming button, which is structured so as to be able to be pressed when mobile unit is coupled to said container, and to be released when said mobile unit is separated from the container itself;
said mobile unit being configured so as to move to a confirmed arming state when said arming button remains pressed for a predetermined arming time interval;
said arming state including the activation of said positioning and communication means. - View Dependent Claims (14)

17. A container tracking system comprising:
-
a mobile unit configured to couple to a container to be tracked and to communicate with a ground control unit through a communication system, the mobile unit comprising a satellite positioning module and a communication module for communicating with a phone network, said mobile unit being configured to change to a low activity state whenever the communication module is unable to communicate with the phone network;
said low activity state providing for switching off said satellite positioning module and said communication module of said mobile unit;wherein said mobile unit is configured to remain in said low activity state for a predetermined wake-up time interval and is adapted to pass to an activation state, at the end of said wake-up time interval and wherein said mobile unit is configured so as to switch from said activation state to a coverage detection state in which said mobile unit checks communication availability through said communication system. - View Dependent Claims (18)
