Abstract
An apparatus, method and system are provided which permit the monitoring of a dunnage bag used as a cushion in the transportation of cargo items which may be typically found in as shipping container. A gas pressure sensor may be attached directly to the dunnage bag and the pressure can be monitored remotely. The gas pressure sensor can also be enclosed within a sealed and pressurized enclosure whereby the gas sensor reading can serve as indication of pressure of a nearby dunnage bag within which the enclosure is in contact. The dunnage bag pressure readings can be wirelessly monitored from a remote location and the bag pressure may be controlled remotely.
Claims22
A gas pressure sensor device for use with a dunnage bag comprising:
- a gas pressure sensor;
- means for communication between said gas pressure sensor and a remote monitoring station;
- and
- an enclosure to which the gas pressure sensor is attached.
A method for determining potential damage to cargo based on detection of a damaged dunnage bag, comprising:
- measuring gas pressure of the dunnage bag using a sensor and wirelessly dispatching readings of the gas pressure to a remote location.
The method as recited in claim 11 wherein measuring the gas pressure of the dunnage bag is accomplished by measuring the gas pressure of a sealed enclosure, including a gas pressure sensor, adjacent at least one cargo item and wedged between the cargo item and a second item.
A method of monitoring dunnage bag pressure, comprising:
- wirelessly receiving pressure data from a sensor measuring dunnage bag pressure.
