Contextually aware monitoring of assets

摘要

An apparatus, method and system for contextually aware monitoring of a supply chain are disclosed. In some implementations, contextually aware monitoring can include monitoring of the supply chain tradelane with tracking devices including sensors for determining location, velocity, heading, vibration, acceleration (e.g., 3D acceleration), or any other sensor that can monitor the environment of the shipping container to provide contextual awareness. The contextual awareness can be enabled by geofencing and recursive algorithms, which allow dynamic modification of the tracking device behavior. Dynamic modification can reduce performance to save power (e.g., save battery usage) and lower costs. Dynamic modification can increase performance where it matters in the supply chain for improved reporting accuracy or frequency or recognition of supply chain events. Dynamic modification can adapt performance such as wireless communications to the region or location of the tracking device.

1. A computer-implemented method, comprising:
receiving tracking data for an asset from a tracking device coupled to the asset, the tracking data including a location of the asset and a timestamp corresponding to the location; utilizing a Hidden Markov Model to assess a shipping context of the asset based on the received tracking data, wherein the shipping context is a predicted state of the asset; determining that a dynamic behavior of the tracking device is to be adjusted based on the shipping context, wherein the dynamic behavior corresponds to an adjustable frequency of data collection at the tracking device and an adjustable frequency of data reporting at the tracking device; and based on the determination, adjusting the dynamic behavior of the tracking device for the asset, wherein adjusting the dynamic behavior includes:
adjusting the frequency of location data collection from a navigation receiver in the tracking device from a first collection frequency to a second collection frequency, andadjusting the frequency of data reporting from the tracking device to a remote server from a first reporting frequency to a second reporting frequency.
