Abstract
Systems and methods for locating collocated assets in accordance with embodiments of the invention are disclosed. In one embodiment of the invention, an asset tracking device includes a processor, a memory connected to the processor, and a communications device connected to the processor, wherein the processor obtains asset signal data, where the asset signal strength data includes asset data identifying an asset, calculates asset signal strength data based on the obtained asset signal data, and determines chained asset data based on the asset signal data and the asset signal strength data, where the chained asset data identifies a set of assets chained to a master asset associated with the asset tracking device.
Claims18
An asset tracking device, comprising:
- a processor;
- a memory connected to the processor;
- and
- a communications device connected to the processor;
- wherein the processor:
- obtains asset signal data, where the asset signal strength data comprises asset data identifying an asset being tracked;
- calculates asset signal strength data based on the obtained asset signal data;
- determines chained asset data based on the asset signal data and the asset signal strength data, where the chained asset data identifies a set of collocated tracked assets chained to a master asset associated with the asset tracking device;
- wherein the asset signal data further comprises synchronization data common to the set of collacated tracked assets;
- and
- wherein the processor further determines the chained asset data based on the synchronization data.
An asset tracking system, comprising:
- a set of collocated asset tracking devices, wherein each asset tracking device comprises a processor, a memory connected to the processor, and a communications device;
- and
- wherein at least one asset tracking device in the set of collocated asset tracking devices:
- transmits asset signal data;
- obtains asset signal data from at least one asset tracking device in the set of collocated asset tracking devices;
- determines aggregate signal strength data for each of the other asset tracking devices in the set of collocated asset tracking devices based on the obtained asset signal data;
- calculates asset position data for every other asset tracking device in the set of collocated asset tracking devices based on the aggregate signal strength data;
- and
- wherein each asset tracking device in the set of collocated asset tracking devices is associated with an asset being tracked, wherein each asset tracking device in the set of collocated asset tracking devices is connected to a synchronization signal on its associated asset;
- and wherein the asset signal data comprises synchronization data that is (1) common to the set of collocated asset tracking devices and (2) determined based on the synchronization signal.
A method for determining the location of an asset, comprising:
- obtaining asset signal data using an asset tracking device, where the asset signal strength data comprises asset data identifying an asset being tracked and the asset tracking device comprises a processor, a memory connected to the processor, and a communications device;
- calculating asset signal strength data based on the obtained asset signal data using the asset tracking device;
- determining chained asset data based on the asset signal data and the asset signal strength data using the asset tracking device, where the chained asset data identifies a set of collocated tracked assets chained to a master asset associated with the asset tracking device;
- wherein the asset signal data further comprises synchronization data common to the set of collocated tracked assets;
- and
- wherein the determining chained asset data further comprises determining the chained asset data based on the synchronization data.
