Abstract

A system for monitoring the integrity of a container having at least one door. The system includes a data interpretation device disposed inside the container. The system further includes a radar sensor interoperably connected to the data interpretation device for monitoring internal conditions of the container and for providing radar data to the data interpretation device, a motion-detection sensor for monitoring motion inside the container, and an antenna interoperably connected to the data interpretation device for communicating information relative to the internal conditions of the container to a location outside the container.

Claims

1. A system for monitoring the integrity of a container having at least one door, the system comprising:

a data interpretation device disposed inside the container;

a radar sensor interoperably connected to the data interpretation device for monitoring internal conditions of the container and for providing radar data to the data interpretation device;

a motion-detection sensor for monitoring motion inside the container; and

an antenna interoperably connected to the data interpretation device for communicating information relative to the internal conditions of the container to a location outside the container.

2. The system of claim 1, wherein the data interpretation device and the radar sensor are mounted to an area adjacent to the at least one door of the container.

3. The system of claim 1, wherein the data interpretation device and the radar sensor are mounted within a generally C-shaped channel of the container.

4. The system of claim 1, wherein the radar sensor is a Micro Impulse Radar.

5. The system of claim 4, wherein the radar sensor is adapted to transmit low-power, wide-band, short duration pulses in the microwave frequency range into an interior region of the container.

6. The system of claim 5, wherein the radar sensor is adapted to detect security breach of the container by detecting a direct current (DC) shift signal and/or a Doppler shift signal inside the container.

7. The system of claim 6, wherein any of a container door movement, human movement, tampering with the container, and cargo shifting results in generation of the direct current (DC) shift signal and the Doppler shift signal.

8. The system of claim 1, wherein the motion-detection sensor is adapted to monitor motion inside the container due to cargo shifting.

9. The system of claim 1, wherein the motion-detection sensor is integrated within the data interpretation device.

10. The system of claim 1, wherein the motion-detection sensor is integrated within the radar sensor.

11. The system of claim 1, wherein the motion-detection sensor is an accelerometer.

12. The system of claim 1, wherein the radar sensor is mounted on a ceiling of the container near the at least one door.

13. The system of claim 1, wherein the data interpretation device includes an interface for receiving the radar data.

14. The system of claim 1, wherein the data interpretation device comprises at least one sensor.

15. A method of monitoring the integrity of a container having at least one door, the method comprising:

disposing inside the container a data interpretation device;

monitoring, via a radar sensor interoperably connected to the data interpretation device and a motion-detection sensor, internal conditions of the container;

providing radar data to the data interpretation device; and

communicating, via an antenna interoperably connected to the data interpretation device, information relative to the internal conditions of the container to a location outside the container.

16. The method according to claim 15, comprising the step of mounting the data interpretation device and the radar sensor to an area adjacent to the at least one door of the container.

17. The method according to claim 15, comprising the step of mounting the data interpretation device and the radar sensor within a generally C-shaped channel of the container.

18. The method according to claim 15, wherein the radar sensor is a Micro Impulse Radar.

19. The method according to claim 18, further comprising the step of transmitting, via the radar sensor, low-power, wide-band, short duration pulses in the microwave frequency range into an interior region of the container.

20. The method according to claim 15, further comprising the steps of:

detecting, via the radar sensor, security breach of the container by detecting a direct current (DC) shift signal and a Doppler shift signal inside the container; and

detecting, via the motion-detection sensor, motion inside the container due to cargo shifting.

21. The method according to claim 20, further comprising the step of activating a security alarm if the direct current (DC) shift signal and/or the Doppler shift signal exceeds a predetermined threshold and a motion-detection measurement does not exceed a motion-detection measurement threshold.

22. The method according to claim 15, wherein the motion-detection sensor is integrated within the data interpretation device.

23. The method according to claim 15, wherein the motion-detection sensor is integrated within the radar sensor.

24. The method of claim 15, further comprising the step of mounting the radar sensor on a ceiling of the container near the at least one door.

25. The method of claim 15, further comprising the step of detecting, via the radar sensor, security breach of the container by detecting a direct current (DC) shift signal and a Doppler shift signal inside the container when the at least one door of the container is opened to exceed a predetermined door opening threshold.

26. The method of claim 15, wherein the data interpretation device comprises at least one sensor.

27. A system for monitoring the integrity of a container having at least one door, the system comprising:

a data interpretation device disposed inside the container;

a radar sensor interoperably connected to the data interpretation device for monitoring internal conditions of the container and for providing radar data to the data interpretation device, the data interpretation device and the radar sensor being mounted within a generally C-shaped channel of the container;

a motion-detection sensor interoperably connected to the data interpretation device; and

an antenna interoperably connected to the data interpretation device for communicating information relative to the internal conditions of the container and the motion inside the container to a location outside the container.
