Abstract

An asset monitoring and security system includes at least one asset assigned a unique identifier and operable wirelessly transmit an identification signal embodying the identifier. A data store maintains a list of the assets and privileges associated with the assets for authorized users of the assets. A control unit is adapted to receive identification signals from the assets and monitor positions of the assets within a defined area. The control unit communicates with the data store and is further operable to initiate an alarm event when privileges associated with a given asset for authorized users of the asset are exceeded. Each of the assets includes a lock-out mechanism that impedes use of the asset when the lock-out mechanism is activated. The control unit activates the lock-out mechanism of a given asset when the privileges associated with the asset for authorized users of the asset are exceeded.

a control unit adapted to receive the identification signal from the asset and monitor a position of the asset within a defined area based on the identification signal, wherein the control unit communicates with the data store and is further operable to activate the lock-out mechanism when privileges associated with the asset for authorized users of the asset are exceeded.

2. The asset monitoring and security system of claim 1 wherein the control unit deactivates the lock-out mechanism when privileges associated with the asset for authorized users of the asset are not exceeded.

3. The asset monitoring and security system of claim 1 wherein the control unit is further operable to initiate an alarm event when privileges associated with the asset for authorized users of the asset are exceeded.

4. The asset monitoring and security system of claim 3 wherein a privilege associated with the asset for authorized users of the asset limits authorized users to possession of the asset within the defined area and wherein the control unit initiates the alarm event when the asset is located outside of the defined area.

5. The asset monitoring and security system of claim 3 wherein the control unit activates at least one of an audible indicator and/or a visible indicator at least one of during and/or after the alarm event.

6. The asset monitoring and security system of claim 3 wherein the control unit includes a wireless transmitter operable to transmit an alarm message to a remote monitoring system at least one of during and/or after the alarm event.

7. The asset monitoring and security system of claim 1 wherein the data store maintains a list of users authorized to use the asset and privileges associated with the asset for each of the authorized users and wherein the control unit is operable to activate the lock-out mechanism when privileges associated with a given authorized user for the asset are exceeded.

8. The asset monitoring and security system of claim 7 wherein the control unit deactivates the lock-out mechanism when privileges associated with a given authorized user for the asset are not exceeded.

9. The asset monitoring and security system of claim 7 wherein the control unit is operable to initiate an alarm event when privileges associated with a given authorized user for the asset are exceeded.

10. The asset monitoring and security system of claim 9 wherein a privilege associated with the asset for a given authorized user limits the authorized user to possession of the asset within the defined area and wherein the control unit initiates the alarm event when the given authorized user possesses the asset outside of the defined area.

11. The asset monitoring and security system of claim 1 further comprises a data input device adapted to receive a personal identifier input by a user that uniquely identifies the user during an asset check-out process.

12. The asset monitoring and security system of claim 11 wherein the data input device is operable to transmit the personal identifier to the data store and wherein the control unit associates the asset with the user based on the personal identifier.

13. The asset monitoring and security system of claim 1 wherein a privilege associated with the asset for authorized users of the asset limits authorized users to possession of the asset within the defined area and wherein the control unit activates the lock-out mechanism of the asset when the asset is located outside of the defined area.

14. The asset monitoring and security system of claim 1 wherein the assets are power tools and the defined area is an industrial job site location.

15. An asset monitoring and security system, comprising:

at least one asset assigned a unique identifier and operable to transmit an identification signal embodying the identifier over a wireless communications link;

a data store for maintaining a list of the assets and privileges associated with the assets for authorized users of the assets; and

a control unit adapted to receive identification signals from the assets and monitor positions of the assets within a defined area based on the identification signals, wherein the control unit communicates with the data store and is further operable to activate a site lighting system that illuminates the defined area when privileges associated with a given asset for authorized users of the asset are exceeded.

16. The asset monitoring and security system of claim 15 wherein the data store maintains a list of users authorized to use the assets and privileges associated with the assets for each of the authorized users and wherein the control unit is operable to activate the site lighting system when privileges associated with a given authorized user for a given asset are exceeded.

17. The asset monitoring and security system of claim 15 further comprises a data input device adapted to receive a personal identifier input by a user that uniquely identifies the user and a list of desired assets input by the user that the user desires to possess during an asset check-out process.

18. The asset monitoring and security system of claim 17 wherein the data input device is operable to transmit the personal identifier and the list of desired assets to the data store and wherein the control unit associates a given asset with the user based on the personal identifier and the list of desired assets.

19. The asset monitoring and security system of claim 15 wherein a privilege associated with a given asset for authorized users of the asset limits authorized users to possession of the asset within the defined area and wherein the control unit activates the site lighting system when the asset is located outside of the defined area.

20. The asset monitoring and security system of claim 15 wherein the control unit is further operable to activate a visible indicator at least one of during and/or after the alarm event.

21. The asset monitoring and security system of claim 15 wherein the control unit repeatedly flashes the site lighting system at least one of during and/or after the alarm event.

22. The asset monitoring and security system of claim 15 wherein the control unit includes a wireless transmitter operable to transmit an alarm message to a remote monitoring system at least one of during and/or after the alarm event.

23. The asset monitoring and security system of claim 15 wherein the assets are power tools and the defined area is an industrial job site location.

24. An asset monitoring and security system, comprising:

at least one asset assigned a unique identifier and operable to transmit an identification signal embodying the identifier over a wireless communications link;
