Abstract

A cargo monitoring system comprising a controller and an image-capturing device for capturing a first image of cargo in response to a first signal from the controller. The system includes a sensor for taking sensor readings in relation to the cargo and for transmitting the sensor readings to the controller. The controller is configured to send a second signal to the image-capturing device to cause the image-capturing device to capture a second image of the cargo if the controller determines from the sensor readings that a cargo-damaging event has occurred.

First claim

The invention claimed is:

1. A cargo monitoring system comprising:
a controller;
an image-capturing device for capturing a first image of cargo in response to a first signal from the controller;
a detachable sensor attached to the cargo for taking sensor readings indicative of a cargo-damaging event in relation to the cargo to which the sensor is attached and for transmitting the sensor readings to the controller;
wherein the controller is configured to send a second signal to the image-capturing device to cause the image-capturing device to capture a second image of the cargo if the controller determines from the sensor readings that a potential cargo-damaging event has occurred; and
a wireless transceiver for receiving a threshold from a remote computing device wherein the threshold is sent to the controller based on a container identifier of a cargo container in which the cargo is located, wherein the controller is configured to cooperate with the wireless transceiver to send an alert to the remote computing device in response to sensing, by the detachable sensor, that the threshold has been exceeded for the container identifier.

2. The system of claim 1 comprising a container sensor that is connected to the cargo container.

3. The system of claim 1 wherein the detachable sensor is an accelerometer.

4. The system of claim 1 wherein the detachable sensor is an acoustic wave sensor.

5. The system of claim 1 wherein the image-capturing device is a camera and wherein the first and second images are photographs.

6. The system of claim 1 wherein the image-capturing device is selected from the group consisting of an X-ray scanner, an infrared camera, and an ultrasound imager.

7. The system of claim 1 wherein the wireless transceiver is configured to transmit one or both of the first and second images to the remote computing device.

8. The system of claim 1 wherein the threshold is a maximum acceptable force.

9. The system of claim 8 further comprising a memory for storing location data of a cargo-damaging location where the cargo-damaging event was sensed wherein the memory is accessible by a vehicle system of a vehicle transporting the cargo to enable avoidance of the location on a subsequent trip.

10. The system of claim 1 wherein the controller cooperates with a vehicle system of a vehicle transporting the cargo to provide an immediate warning to a driver of the vehicle that the cargo is being subjected to excessive movement.

11. The system of claim 1 wherein the wireless transceiver is configured to transmit location data of a cargo-damaging location where the cargo-damaging event was sensed to other vehicles to enable the other vehicles to avoid the location.

12. A method of monitoring cargo, the method comprising:
capturing a first image of cargo using an image-capturing device in response to a first signal from a controller;
taking sensor readings indicative of a cargo-damaging event in relation to the cargo using a detachable sensor attached to the cargo;
transmitting the sensor readings to the controller;
determining by the controller if the sensor readings are indicative of a cargo-damaging event;
sending a second signal to the image-capturing device to cause the image-capturing device to capture a second image of the cargo subjected to the cargo-damaging event;
wirelessly receiving a threshold from a remote computing device wherein the threshold is sent to the controller based on a container identifier of a cargo container in which the cargo is located; and
wirelessly transmitting an alert to the remote computing device in response to sensing, by the detachable sensor, that the threshold has been exceeded.

13. The method of claim 12 wherein the threshold is a maximum acceptable force and wherein the detachable sensor is an accelerometer or an acoustic wave sensor.

14. The method of claim 12 wherein the image-capturing device is a camera and wherein the first and second images are photographs.

15. The method of claim 12 wherein the image-capturing device is selected from the group consisting of an X-ray scanner, an infrared camera, and an ultrasound imager.

16. The method of claim 12 further comprising transmitting one or both of the first and second images to the remote computing device.

17. The method of claim 12 further storing location data of a cargo-damaging location where the cargo-damaging event was sensed.

18. The method of claim 17 wherein the location data is stored in a memory that is accessible by a vehicle system of a vehicle transporting the cargo to enable avoidance of the location on a subsequent trip.

19. The method of claim 12 further comprising providing an immediate warning to a driver of a vehicle carrying the cargo that the cargo is being subjected to excessive movement.

20. The method of claim 12 further transmitting location data of a cargo-damaging location where the cargo-damaging event was sensed to other vehicles to enable the other vehicles to avoid the location.
