Network system for autonomous data collection
View Patent ↗A system to monitor and report asset inventory and status on board a vehicle, for example, an aircraft. This system has low weight and provides high reliability. Energy harvesting is provided for applications where it is difficult to connect to a power source. In one embodiment, a sensor communicates with the asset. An RFID tag is affixed to the asset and communicates with the asset. The RFID tag containing digitally stored information about the asset. An RFID reader mounted to the vehicle and positioned such that the RFID tag is within communication range with the RFID reader. A data delivery system effective to digitally transmit information from the RFID reader to a data collection system. A secure interface disposed between the data collection system and a communication system with the communication system effective to transmit the information to a flight crew, a ground crew and/or a display.
1. A system to monitor and to reporting a status of assets on a vehicle, comprising:
a plurality of RFID tags, each RFID tag affixed to a particular asset and containing digitally stored information about the particular asset;
a plurality of RFID readers mounted to said vehicle and positioned such that each one of the plurality of RFID tags is within communication range with at least one RFID reader;
a data delivery system effective to digitally transmit information from the plurality of RFID readers to a data collection system;
a secure interface disposed between the data collection system and a communication system; and
the communication system effective to transmit the information to one or more of a flight crew and a ground crew.
2. The system of claim 1 wherein at least one of the RFID tags is an active tag.
3. The system of claim 2 wherein at least one of the RFID tags is a passive tag.
4. The system of claim 2 wherein the active tag is connected to a power source.
5. The system of claim 2 wherein the active tag is connected to an energy harvester.
6. The system of claim 5 wherein the energy harvester is effective to harvest energy from a source selected from the group consisting of a light source, a thermal source, a vibration source, an RF source and combinations thereof.
7. The system of claim 6 further including an energy storage system.
8. The system of claim 7 wherein the energy storage system is selected from the group consisting of rechargeable batteries and capacitors.
9. The system of claim 6 wherein the energy harvester is a solar cell and at least a portion of the particular asset adjacent to the solar cell is light transmitting.
10. The system of claim 1 wherein the data delivery system is selected from the group consisting of an Ethernet interconnect and a wireless connection.
11. The system of claim 10 wherein the secure interface is protected by a service set identifier (SSID).
12. A system to monitor and to reporting a status of assets on a vehicle, comprising:
a sensor in communication with an asset and effective to monitor a property of the asset;
an RFID tag affixed to the asset and in communication with the asset, the RFID tag containing digitally stored information about the asset;
an RFID reader mounted to said vehicle and positioned such that the RFID tag is within communication range with the RFID reader;
a data delivery system effective to digitally transmit information from the RFID reader to a data collection system;
a secure interface disposed between the data collection system and a communication system; and
the communication system effective to transmit the information to one or more of a flight crew, a ground crew and a display.
13. The system of claim 12 wherein the sensor is effective to measure a property selected from the group consisting of a flashlight charge, an oxygen bottle pressure, a fire extinguisher pressure and a storage bin volume.
14. The system of claim 13 wherein the sensor measures storage bin volume and the display is mounted on the vehicle.
15. The system of claim 13 wherein the sensor measures storage bin volume and the display is contained within a passenger's personal electronic device.
16. The system of claim 13 wherein the sensor is a proximity sensor.
17. The system of claim 13 wherein at least one of the RFID tags is an active tag.
18. The system of claim 17 wherein the active tag is connected to an energy harvester.
19. The system of claim 18 further including an energy storage system.
20. The system of claim 19 wherein the energy storage system is selected from the group consisting of rechargeable batteries and capacitors.
