Abstract

A commercially acceptable solution to provide for monitoring battery voltage of an asset, managing charging of batteries of a group of assets, and managing scheduled maintenance of assets may utilize system architecture having intelligent wireless devices associated with the individual assets. The use of intelligent wireless devices allows for the asset management system to operate and maintain functionality substantially without loss of data in the event of a loss of communication between the wireless devices and a management computing system via a network, including an out-of-range condition of the wireless devices with respect to a local monitor.

Claims

1. A system, comprising:

a central processing node for monitoring mobile asset operations, the central processing node receiving mobile asset related operational data over at least one wireless communication link;

a first mobile asset monitor for collecting mobile asset related operational data from a first mobile asset;

a first wireless communication device associated with the first mobile asset monitor for wirelessly communicating with the central processing node over the at least one wireless communication link;

one or more second mobile asset monitors for collecting mobile asset related operational data from one or more second mobile assets;

one or more second wireless communication devices, each of the one or more second wireless communication devices being associated with one of the one or more second mobile assets for wirelessly communicating with the first wireless communication device and the central processing node over the at least one wireless communication link; and

a first mobile asset processing device for;

attempting to establish a direct communication link between the first wireless communication device and the central processing node over the at least one wireless communication link;

if a direct communication link was established between the first wireless communication device and the central processing node, transmitting the collected mobile asset related operational data directly to the central processing node;

if a direct communication link was not established between the first wireless communication device and the central processing node, then establishing an indirect communication link between the first wireless communication device and the central processing node through at least one of the one or more second wireless communication devices;

if the indirect communication link was established between the first wireless communication device and the central processing node, transmitting the collected mobile asset related operational data indirectly to the central processing node via the indirect communication link; and

supporting indirect communications between one or more of the second wireless communications devices and the central processing node by receiving mobile asset related operational data from the one or more second wireless communications devices and transmitting the received mobile asset related operational data to the central processing node, either directly or indirectly, as a communications intermediary between one or more of the second wireless communications devices and the central processing node.

2. The system of claim 1 wherein the collected mobile asset related operational data includes a listing of devices through which that data has previously been indirectly communicated, the means in each device for indirectly transmitting further choosing the indirect communication which would require the fewest number of hops and which does not pass through a device included on the listing.

3. The system according to claim 1, wherein each of the wireless communication devices includes a memory operable to store the mobile asset related operational data at least until that data is transmitted.

4. The system according to claim 1, wherein each wireless communication device further includes means for forming an identifier associated with the mobile asset related operational data, the identifier possessing a temporal indication distinguishing that data from other mobile asset related operational data.

5. The system according to claim 1, wherein each wireless communication device further includes means for determining whether the mobile asset related operational data has become obsolete, and if so inhibiting transmitting of that data.

6. The system according to claim 5 wherein mobile asset related operational data is obsolete if superseded by newer mobile asset related operational data.

7. The system according to claim 6 wherein the newer mobile asset related operational data is received by the device in an indirect transmission from another device.

8. The system according to claim 1, wherein the first mobile asset processing device determines a path to the central processing node having the least number of communication hops.

9. The system according to claim 1, wherein the first mobile asset processing device combines the mobile asset related operational data collected from the first mobile asset with mobile asset related operational data collected from one or more of the one or more second mobile assets for transmission to the central processing node.

10. The system according to claim 1, wherein the first mobile asset processing device stores the mobile asset related operational data in a mobile asset data storage device if neither the direct communication link nor the indirect communication link could be established between the first wireless communication device and the central processing node.

11. The system according to claim 10, wherein the first mobile asset processing device attempts to establish a direct or indirect communication link between the first wireless communication device and the central processing node periodically until either a direct or indirect communication link is established between the first wireless communication device and the central processing node.

12. The system according to claim 11, wherein the first mobile asset processing device retrieves the mobile asset related operational data from the mobile asset data storage device and transmits it to the central processing node upon successfully establishing a direct communication link with the central processing node.

13. The system according to claim 11, wherein the first mobile asset processing device retrieves the mobile asset related operational data from the mobile asset data storage device and transmits it to the central processing node upon successfully establishing an indirect communication link with the central processing node.
