Abstract

A method, system, and/or computer program product determines conditions of intermodal shipping containers on a cargo ship. A processor establishes a baseline composite vibration pattern from readings generated by multiple vibration sensors that are affixed to multiple intermodal shipping containers on a cargo ship. Subsequent readings are taken from the multiple vibration sensors to generate a new composite vibration pattern. The processor also receives humidity readings from humidity sensors that are affixed to interiors of the multiple intermodal shipping containers, and then combines the humidity readings with the new composite vibration pattern to create a vibration/humidity pattern. In response to the new composite vibration pattern being different from the baseline composite vibration pattern, the processor matches the vibration/humidity pattern with a known vibration/humidity pattern in order to identify a cause of the new vibration/humidity pattern and a condition of the intermodal shipping containers.
