SYSTEMS AND METHODS FOR MONITORING TRANSPORTED CARGO

摘要

Systems and methods relating to monitoring cargo are provided. Various embodiments provide features relating to: (1) monitoring characteristics of cargo using a single device that may be disposable; (2) generating alerts based on a variety of temperature conditions, such as multiple temperature thresholds; (3) providing multiple levels of alerts and escalating alerts to different users; (4) providing an indication of an end of trip based on location data and data from sensor(s); (5) reducing power of transmissions between devices; (6) using frequency diversity features to communicate between devices; (7) providing configurable reporting and/or sensor monitoring parameters, and changing reporting and/or sensor measurement periods; (8) allowing for communication with devices across multiple frequency bands; (9) utilizing secondary communication circuits to communicate with different devices, such as across different frequency channels and/or bands; and (10) using a movement detection device (e.g., an accelerometer) to reduce false indications of movement.

1. A method comprising:
determining one or more characteristics relating to cargo during transportation of the cargo using data collected by a portable monitoring device, the portable monitoring device configured to periodically transmit a signal generated using the data to a remote computing device via a network; and changing at least one of the following based on the one or more characteristics relating to the cargo:
a first period at which the signal is transmitted by the portable monitoring device; ora second period at which one or more sensors of the portable monitoring device collect the data used to determine the one or more characteristics.
