Abstract

Disclosed herein are systems and methods for location-based validation of personal protection equipment (PPE) for use with an aerial work platform (AWP). In one such method, an AWP is provided with a user hub. The user hub stores information identifying one or more radio frequency identification (RFID) tags that are affixed to PPE that is required for the use of the AWP. Through a near-field antenna mounted at the operator basket of the AWP, the user hub determines whether the required PPE is within range of the antenna before permitting a lift operation to be performed by the AWP. In some embodiments, the user hub may disable the AWP or initiate an emergency shutdown if the required PPE is not present.

Claims

1. A method comprising:

receiving, at a user hub, data identifying a near-field identification tag associated with personal protection equipment;

receiving, at the user hub, an indication that a lift operation is being initiated at an aerial work platform having an operator basket;

operating the user hub to determine whether the near-field identification tag is within range of an antenna mounted on the operator basket; and

permitting the lift operation to proceed only after determining that the near-field identification tag is within range of the antenna.

2. The method of claim 1, further comprising determining, at the user hub, that the operator basket has reached a threshold height;

in response to the determination that the operator basket has reached a threshold height, operating the user hub to determine whether the near-field identification tag remains within range of the antenna; and

permitting the lift operation to proceed only after determining that the near-field identification tag remains within range of the antenna.

3. The method of claim 1, further comprising:

determining, at the user hub, that the operator basket has reached a threshold height;

in response to the determination that the operator basket has reached a threshold height, operating the user hub to determine whether the near-field identification tag remains within range of the antenna;

determining that the near-field identification tag is no longer in range of the antenna; and

in response to the determination that the near-field identification tag is no longer in range of the antenna, disabling the lift operation.

permitting the lift operation to proceed only after determining that the near-field identification tag remains within range of the operator basket.

4. The method of claim 3, wherein disabling the lift operation includes activating an emergency shutdown of the aerial work platform.

5. The method of claim 1, wherein the near-field identification tag is an RFID tag.

6. The method of claim 1, wherein the receiving of data identifying the near-field identification tag associated is performed over a wireless network.

7. The method of claim 1, further comprising:

receiving, at the user hub, data identifying a permitted operation area associated with the aerial work platform;

operating the user hub to determine a location of the aerial work platform; and

permitting the lift operation to proceed only after determining that the user hub is in the permitted operation area.

8. The method of claim 1, wherein the user hub is mounted on a base of the aerial work platform.

9. The method of claim 1, wherein the user hub is mounted on the operator basket of the aerial work platform.

10. The method of claim 1, wherein the aerial work platform is a cherry-picker.

11. An apparatus comprising:

a user hub having a processor, a non-transitory computer memory, and a near-field interface including an antenna mounted on an operator basket of an aerial work platform, wherein the computer memory stores instructions that, when executed on the processor, are operative;

to store, in the computer memory, data identifying a near-field identification tag associated with personal protection equipment;

to receive an indication that a lift operation is being initiated at an aerial work platform having an operator basket;

to determine whether the near-field identification tag is within range of the antenna; and

to permit the lift operation to proceed only after determining that the near-field identification tag is within range of the antenna.

12. The method of claim 11, wherein the user hub further includes a wireless network interface, and wherein the instructions are further operative to receive, over the wireless network interface, the data identifying the near-field identification tag.

13. The method of claim 12, wherein the wireless network interface operates according to one or more wireless-communication formats selected from the group consisting of radio frequency (RF), cellular wireless, time division multiple access (TDMA), code division multiple access (CDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), Evolution Data Optimized (EV-DO), Long Term Evolution (LTE), Wi Fi, WiMAX, Global System for Mobile communications (GSM), general packet radio service (GPRS), and Universal Mobile Telecommunication System (UMTS).

14. The method of claim 11, wherein the near-field interface operates according to one or more wireless-communication formats selected from the group consisting of radio frequency (RF), RF in a 13.56 MHz band, RF in a 433 MHz band, RF in an 865 868 MHz band, RF in a 902 928 MHz band, RF in a 2450 5800 MHz band, RF in a 3.1 10 GHz band, Bluetooth, and Wi Fi.

15. An aerial work platform comprising:

a base,

an operator basket,

a boom arm mounted between the base and the operator basket, the boom arm being operative to lift the operator basket during a lift operation;

lift circuitry operative to control the lift operation of the boom arm;

a near-field antenna mounted at the operator basket;

a user hub in communication with the lift circuitry, the user hub having a processor and a non-transitory computer memory, wherein the computer memory stores instructions that, when executed on the processor, are operative;

to store, in the computer memory, data identifying a near-field identification tag associated with personal protection equipment;

to receive an indication that a lift operation is being initiated;

to determine whether the near-field identification tag is within range of the antenna; and

to permit the lift operation to proceed only after determining that the near-field identification tag is within range of the antenna.

16. The aerial work platform of claim 15, wherein the personal protection equipment is a lanyard to which a near-field identification tag is affixed.

17. The aerial work platform of claim 15, wherein the personal protection equipment is a harness to which a near-field identification tag is affixed.

18. The aerial work platform of claim 15, wherein the user hub further includes a wireless network interface, and wherein the instructions are further operative to receive, over the wireless network interface, the data identifying the near-field identification tag.

19. The aerial work platform of claim 18, wherein the wireless network interface operates according to one or more wireless-communication formats selected from the group consisting of radio frequency (RF), cellular wireless, time division multiple access (TDMA), code division multiple access (CDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), Evolution Data Optimized (EV-DO), Long Term Evolution (LTE), Wi Fi, WiMAX, Global System for Mobile communications (GSM), general packet radio service (GPRS), and Universal Mobile Telecommunication System (UMTS).

20. The aerial work platform of claim 15, wherein the instructions are further operative:

to monitor whether an operator basket of the aerial work platform has reached a threshold height;

in response to a determination that the aerial work platform has reached the threshold height, to determine whether the near-field identification tag remains within range of the antenna; and

in response a determination that the near-field identification tag is not in range of the antenna, to disable the lift operation.
