System and method for providing communications for container security
View Patent ↗A system for providing communications for container security is provided. The system includes a sensing system for monitoring the contents of the container; a signal receiving element for receiving sensor data from the sensing system; a control element for analyzing received sensor data; a first transceiver element for receiving signals containing sensor data from within the container and for transmitting those signals outside of the container; and a satellite transceiver element for receiving signals from the first transceiver element and for forwarding the received signals via satellite uplink to a remote location.
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 comprises:
at least one monitored container which includes sensors for monitoring at least two aspects of the physical status of the monitored container;
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 further wherein the container level processing element is further configured to produce and transmit at least a first set of container level data and a second set of container level data, wherein the second set of container level data includes data regarding at least one aspect of the physical status of the container not included in the first set of container level data;
wherein the container level processing element is configured to aggregate container level data from multiple sensors.
2. The system of claim 1 , wherein the container level processing element is configured to change the sampling time interval of a sensor based on a detected change in the container status.
3. The system of claim 1 , wherein the sensor level processing element comprises a sensor, a microprocessor element, and a wired or wireless communications device.
4. The system of claim 3 , 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.
5. 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; and
sending collected data and comparison results onto the multi-container processing element.
6. The system of claim 1 , wherein the multi-container processing element performs several functions comprising:
collecting information from multiple carrier level elements; and
identifying overall trends of activity and events for container shipments based on statistical analysis of processed data from multiple carrier level processing elements.
7. A container monitoring system having a plurality of containers transported by one or more carriers, the system comprising:
at least one monitored container,
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 further wherein the container level processing element is configured to produce and transmit at least a first set of container level data and a second set of container level data, wherein the second set of container level data includes data regarding at least one aspect of the physical status of the container not included in the first set of container level data; and
a multi-container processing element for processing container level data, wherein the multi-container level data processing element is configured to aggregate container level data from multiple containers.
