Abstract

A hierarchical and distributed system architecture for a container monitoring and security system is provided. The architecture may be a hierarchical chain of separate, related processing elements. The partitioning of functions and distribution of processing among these or other similar hierarchical elements in the network is provided. The elements may further be described in successive layers, each have a greater level of network intelligence than the former.

1. A hierarchical network system architecture of multiple levels and distributed processing elements for a container monitoring system having a plurality of containers transported by one or more carriers, wherein the system includes at least one monitored container which includes sensors for monitoring at least two aspects of the physical status of the monitored container, wherein the system comprises:

a data fusion center processing element which is configured to aggregate data from multiple monitored processing elements, wherein the multiple monitored processing elements comprise at least two carrier level processing elements;

wherein each carrier level processing element is configured to receive and analyze container level data from a group of container level processing elements, and to produce and transmit carrier level data to the data fusion center;

wherein each container level processing element is configured to receive and analyze sensor level data from a sensor level processing element, and to produce and transmit container level data;

wherein the sensor level processing element comprising one or more sensors; and

the sensor level processing element is further configured to produce and transmit the sensor level data to the container level processing element.

2. The system of claim 1, wherein the container level processing element receives raw or processed data from one or multiple sensor level processing elements, the container level processing element performing several functions comprising:

comparing sets of sensor data over a fixed or variable time interval;

comparing data from one type of sensor to data collected from another type of sensor to determine a higher level event that may have occurred;

querying said sensor elements for additional data or collecting additional sensor data readings; and

sending collected data and comparison results onto the corresponding carrier level processing element above the container level processing element.

3. The system of claim 1, wherein the each carrier level processing element performs several functions comprising:

collecting data from multiple containers being transported or being stored in a staging area; and

sending collected data onto a data fusion center processing element.

4. The system of claim 1, wherein the data fusion center processing element performs several functions comprising:

collecting information from the at least two carrier level processing elements;

identifying regional level issues based on the at least two carrier level processing elements;

identifying overall trends of activity and events for container shipments based on processed data;

prioritizing information based on predetermined importance of certain types of events; and

formatting information in a graphical manner for a human operator to understand and take appropriate action.

5. The system of claim 1, wherein the each carrier level processing element further comprises an additional container level processing element.

6. The system of claim 1, wherein the each carrier level processing element is configured to monitor multiple containers that are transported together in a shipment, or stored in a storage area.

7. The system of claim 1, wherein the each carrier level processing element is configured to request a second set of container level data from the container level processing unit based on the analysis of a first set of container level data.

8. The system of claim 1, wherein the sensor level processing element comprises a sensor, a microprocessor element, a wired or wireless communications device, and an analog to digital converter.

9. The system of claim 8, wherein the sensor includes at least one sensor from a group of sensors containing:

temperature sensor, visible light sensor, acoustic sensor, vibration sensor, motion sensor, microbolometer, radiation sensor, hazardous chemical sensor, explosives sensor, proximity sensor, infrared sensor, door switch sensor, image capture sensor, and smoke detector.

10. The system of claim 8, wherein the sensor level processing element collects raw sensor data and performs functions comprising:

data smoothing;

data filtering and reduction;

sending the smoothed, filtered, and reduced data onto the container level processing element.

11. A container monitoring system having a plurality of containers transported by one or more carriers, wherein the system includes at least one monitored container which includes sensors for monitoring at least two aspects of a physical status of the monitored container, wherein the network system comprises:

a sensor level processing element comprising one or more sensors, wherein the sensor level processing element is further configured to produce and transmit sensor level data;

a container level processing element, wherein the container level processing element receives and analyzes data provided by at least two sensors located within a single container; and
