Abstract

A tracking and monitoring device for a shipping container has a body section attachable to an inside surface of the container proximate the door frame such that an end protrudes through a gap in the door frame. Security sensors integrally mounted in the body section are coupled to a CPU for detecting a respective security event. A global position sensor in the body section provides a position signal, and a cellular or satellite modem and a long-range antenna in the body section allow long range communication with a remote monitoring center. Power is provided to the device and associated components via a battery. In order to minimize power consumption, the CPU is normally dormant and a power management controller monitors battery power level and awakens the CPU in response to sensor signals and external interrogation signals or interrupts.

Claims

1. A container device for a container tracking and monitoring system used for tracking a sea-worthy shipping container, said container device comprising:

a sealed body section configured for withstanding harsh environments and for attachment to an inside surface of a container proximate a door frame thereof such that a first end of the body section protrudes through a gap in the door frame,

one or more security sensors integrally mounted in the body section and coupled to a processing unit for detecting a respective security event, the processing unit being normally dormant so as to minimize power consumption,

a global position sensor integrally mounted in the body section and coupled to the processing unit for providing a position signal,

a cellular or satellite modem integrally mounted in the body section and coupled to the processing unit for providing data communication carrier via long range networks,

a sealed battery housing within the body section for accommodating a battery for providing power to the container device and to the sensors and the cellular or satellite modem therein,

a power management controller for monitoring battery power level and being responsive to sensor signals and external interrogation signals or interrupts for awakening the processing unit, and

an antenna module mounted at the first end of the body section and coupled to the processing unit, said antenna module including at least one long-range antenna for effecting continuous real time tracking and communication with a remote tracking server for informing the tracking server of an instantaneous location in space of the container and any security events;

wherein;

the antenna module includes a short-range antenna for allowing short-range communication between respective devices in different containers, and

the processing unit is responsive to impaired long-range communication for conveying data to a nearby device in another container via the short-range antenna for relaying to the tracking server.

2. The device according to claim 1, comprising:

a high-sensitive light sensor coupled to the processing unit for providing an alert signal in response to entry of light into the container, and

an accelerometer for providing a signal upon impact or sudden movement.

5. The device according to claim 1, wherein the body section is formed of ferromagnetic material allowing it to be supported on an inner metal surface of the container by one or more permanent magnets.

6. The device according to claim 1, further comprising a contact sensor for providing an alert signal when the device loses contact with the inner surface of the container.

7. The device according to claim 1, further comprising a door sensor coupled to the processing unit for producing a signal when a door of the container is closed or opened.

8. The device according to claim 1, wherein the body section is welded to the processor module and to the antenna module.

9. The device according to claim 1, wherein the one or more security sensors include any one or more in the group consisting of:

temperature sensor, Oxygen and CO₂ sensors, radioactive sensor, accelerometer, humidity sensor.

10. A system for tracking sea-based shipping containers each containing a device according to claim 1, said system including:

a server for sea-worthy shipping tracking containers in real time, each of the containers containing a module that includes an antenna module having a GPS antenna for communicating with two or more satellites for conveying to the server spatial location of the respective module;

said antenna module including a long-range antenna for conveying data indicative of security events to the server and being configured to allow the server to communicate with a device in a specific container.

11. The system according to claim 10, wherein at least one of the containers is used to transport cold food and includes a refrigeration unit.

12. The system according to claim 10, wherein the server stores a user interface accessible by an end user over the Internet.

13. The system according to claim 12, wherein the user interface allows the end user to customize and define alerts for different security events and to define a destination for each alert and a mode of communication therewith.

14. The system according to claim 12, wherein the user interface allows the end user to define a procedure to be taken upon occurrence of an event.

15. The system according to claim 10, wherein:

the time period between interrogations is preset and stored in a memory of the device;

the power management controller awakens the CPU and associates with the current status a timestamp that is stored with the status in the memory

the power management controller is responsive to a measured lapsed time from the most recent timestamp exceeding the preset time interval between interrogations for awakening the CPU for determining a subsequent status of the container.

16. The system according to claim 15, wherein the time interval between interrogations is automatically computed as a function of estimated voyage time.
