REFRIGERATED CONTAINER MONITORING SYSTEM
First Claim
1. A monitoring system for a refrigerated container comprising temperature-sensitive cargo, the monitoring system comprising:
- a plurality of sensors, each of said sensors adapted to describe at least one parameter of said container or said cargo;
a motion sensor adapted to detect movement of said container, and further adapted to generate a first signal in response to said movement;
a data processor in communication with said plurality of sensors and said motion sensor, said data processor adapted to receive said parameter descriptions and said first signal, and further adapted to process said parameter descriptions and said first signal into a second signal capable of transmission;
a transceiver in communication with said data processor and adapted to transmit said second signal to a signal network; and
a control center, said control center adapted to receive said second signal.

Abstract
A monitoring system for a refrigerated container carrying temperature-sensitive cargo. The system includes sensors disposed throughout the container and/or an associated vehicle for measuring parameters of the container or vehicle, including temperature, motion, and fuel efficiency, among many others. The system optionally includes a global positioning system receiver to monitor geographic location. The system communicates with a command center to allow real-time tracking and monitoring of the container. To reduce false positive alerts, the system buffers alerts by at least 30 minutes and blocks signal transmission when the container is located within specified geofences such as loading and unloading sites.
