Abstract
Disclosed is a data recording unit and a data recording system for use in connection with a vehicle, such as a train, a locomotive, a railcar of a train, and the like.
Claims27
A data recorder unit comprising:
- a data recorder enclosure configured to house an internal component;
- a data processing unit located in the data recorder enclosure and configured to receive data from a data source associated with a vehicle;
- and
- a storage device in communication with the data processing unit and configured to store the data received by the data processing unit,
- wherein the storage device comprises one or more of a crash-hardened memory or a fire-resistant memory, wherein the storage device is configured to throttle a power dissipation of the storage device based at least partially upon a sensed temperature.
2 more elements
A data recorder unit comprising:
- a data recorder enclosure configured to house an internal component;
- a data processing unit located in the data recorder enclosure and configured to receive data input from a data source associated with a vehicle;
- a data storage device in communication with the data processing unit and configured to store the data received by the data processing unit;
- and
- an energy storage device configured to store electrical energy and provide the electrical energy responsive to a main power supply to the storage device being lost, removed, or unavailable,
- wherein the energy storage device is in electrical communication with the data processing unit, and wherein the data processing unit is configured to store, on the data storage device and using the electrical energy that is stored, the data input from the data source after the main power supply is lost, removed, or unavailable.
3 more elements
A vehicle data recorder unit comprising:
- a data recorder enclosure configured to house an internal component;
- a data processing unit located in the enclosure and configured to receive data input from a data source associated with a vehicle;
- a storage device in communication with the data processing unit and configured to store the data received by the data processing unit;
- and
- a first energy storage device configured to store electrical energy and provide the electrical energy that is stored responsive to a main power supply being lost, removed, or unavailable,
- wherein the data source comprises a video camera in electrical communication with a second energy storage device, and wherein the video camera is configured to communicate video data responsive to a power supply to the video camera is lost or removed using electrical energy that is stored by the second energy storage device.
3 more elements
A data recorder unit comprising:
- at least one data recorder enclosure configured to house at least one internal component;
- at least one data processing unit located in the enclosure and configured to directly or indirectly receive data input from at least one data source associated with a vehicle;
- and
- at least one storage device in communication with the at least one data processing unit and configured to store data received from the at least one data processing unit, wherein the at least one storage device comprises at least one first storage device comprising at least one non-crash-hardened memory and at least one second storage device comprising at least one crash-hardened memory,
- wherein the at least one data processing unit is configured to store at least a portion of the data on the at least one crash-hardened memory, and
- wherein the at least one crash-hardened memory is configured to transfer the portion of the data stored on the at least one crash-hardened memory to the at least one non-crash-hardened memory.
3 more elements
A data recorder unit for a vehicle, comprising:
- at least one data recorder enclosure configured to house at least one internal component;
- at least one data storage device comprising at least one crash-hardened memory, the at least one data storage device located in the at least one data recorder enclosure;
- and
- at least one data processing unit located in the at least one data recorder enclosure and configured to receive data from a plurality of data inputs and synchronize data from the plurality of data inputs based at least partially on at least one of:
- first time data from at least one internal time source or second time data from a first data input of the plurality of data inputs,
- wherein at least two of the data inputs are stored in separate logical partitions of the at least one crash-hardened memory.
