Abstract

An adaptive method and system for monitoring a shipping container for an environmental anomaly uses sensor-based ID nodes within the container and a command node. Sensors on each ID node generate sensor data about an environmental condition proximate the ID node as disposed within the container. Each ID node periodically broadcasts the sensor data. The command node monitors a first group of sensor data from the ID nodes over a first time period to detect an initial environmental threshold condition related to the container, then monitors a subsequent group of sensor data over a second time period under a modified monitoring parameter to detect a secondary environmental threshold condition related to the container as the anomaly. In response to detecting the secondary condition, the command node generates an alert notification and transmits the alert notification to an external transceiver to initiate a mediation response related to the anomaly.

First claim

What is claimed is:

1. An adaptive method for monitoring a shipping container for an environmental anomaly using a wireless node network having at least a plurality of ID nodes disposed within the shipping container and a command node mounted to the shipping container, wherein each of the ID nodes having at least one environmental sensor, and wherein the command node being operative to communicate with each of the ID nodes and an external transceiver associated with a transit vehicle, the method comprising:
generating, by the environmental sensor on each of the ID nodes, sensor data related to an environmental condition proximate the respective ID node as disposed within the shipping container;
periodically broadcasting, by each of the ID nodes, the sensor data generated by each of the ID nodes over time;
monitoring, by the command node, a first group of the sensor data broadcast from each of the ID nodes over a first time period to detect an initial environmental threshold condition related to the shipping container;
monitoring, by the command node, a subsequent group of the sensor data broadcast from each of the ID nodes over a second time period under a modified monitoring parameter to detect a secondary environmental threshold condition related to the shipping container as the environmental anomaly;
generating, by the command node, an alert notification related to the environmental anomaly for the shipping container in response to detecting the secondary environmental threshold condition; and
transmitting, by the command node, the alert notification to the external transceiver to initiate a mediation response related to the environmental anomaly.

2. The method of claim 1 , wherein the modified monitoring parameter defines which of the ID nodes to consider when detecting the secondary environmental threshold condition.

3. The method of claim 2 , wherein each of the ID nodes is associated with one of a plurality of packages; and
wherein the modified monitoring parameter defines which of the ID nodes to consider when detecting the secondary environmental threshold condition based upon a type of material within each of the packages as associated with a respective one of the ID nodes according to shipping information maintained by the command node, the shipping information identifying the type of material within each of the packages and as related to one of the ID nodes.

4. The method of claim 1 , wherein the modified monitoring parameter defines one or more types of the sensor data broadcast from each of the ID nodes to consider when detecting the secondary environmental threshold condition.

5. The method of claim 4 , wherein the type of the sensor data comprises one from a group of temperature sensor data, pressure sensor data, chemical sensor data, and radiation sensor data.

6. The method of claim 1 , wherein the step of monitoring the subsequent group of the sensor data over the second time period under the modified monitoring parameter comprises instructing, by the command node, each of the ID nodes to change a messaging rate used to regulate how often the generated sensor data is broadcast during the second time period.

7. The method of claim 6 , wherein the instructing step further comprises instructing, by the command node, each of the ID nodes to increase the messaging rate from a default messaging rate used during the first time period to a higher secondary messaging rate used during the second time period.

8. The method of claim 6 , wherein the instructing step further comprises instructing, by the command node, each of the ID nodes to decrease the messaging rate from a default messaging rate used during the first time period to a slower secondary messaging rate used during the second time period.

9. The method of claim 6 , wherein the instructing step further comprises
instructing, by the command node, a first group of the ID nodes to increase the messaging rate from a default messaging rate used during the first time period to a higher secondary messaging rate used during the second time period; and
monitoring, by the command node, the subsequent group of the sensor data broadcast from only the first group of the ID nodes over the second time period to detect the secondary environmental threshold condition related to the shipping container as the environmental anomaly.

10. The method of claim 1 , wherein the mediation response related to the environmental anomaly comprises causing a fire suppression system to dispense fire suppressant material into the shipping container.

11. The method of claim 1 , wherein the mediation response related to the environmental anomaly comprises generating a prompted message requesting an inspection of the shipping container.

12. The method of claim 1 , wherein the mediation response related to the environmental anomaly comprises generating a prompted message requesting the transit vehicle alter course as a result of the environmental anomaly.

13. The method of claim 1 , wherein the command node comprises a mobile master node.

14. The method of claim 1 , wherein the command node comprises a mobile master node permanently attached to the shipping container.

15. The method of claim 1 , wherein the command node comprises a mobile master node integrated as part of the shipping container.

16. The method of claim 1 , wherein the command node comprises a mobile master node implemented separately from the shipping container and removably attached to the shipping container.

17. The method of claim 1 , wherein the mobile master node is mounted to the shipping container within a shipment pouch disposed on the container.

18. The method of claim 1 , wherein the environmental sensor comprises at least one from a group consisting of a temperature sensor, a barometric pressure sensor, a movement sensor, a light sensor, a humidity sensor, a magnetic field sensor, an altitude sensor, an attitude sensor, an orientation sensor, an acceleration sensor, a radiation sensor, and a chemical sensor.

19. The method of claim 1 , wherein the environmental sensor comprises a plurality of sensor elements, the sensor elements comprising at least two from a group consisting of a temperature sensor, a barometric pressure sensor, a movement sensor, a light sensor, a humidity sensor, a magnetic field sensor, an altitude sensor, an attitude sensor, an orientation sensor, an acceleration sensor, a radiation sensor, and a chemical sensor.

20. An adaptive monitoring system for detecting an environmental anomaly in a shipping container, the system comprising:
a plurality of ID nodes disposed within the shipping container, wherein each of the ID nodes comprising
an ID node processor,
an ID node memory coupled to the ID node processor, the memory maintaining at least an ID node monitoring program code,
at least one environmental sensor configured to generate sensor data related to an environmental condition proximate the ID node as disposed within the shipping container, and
