Abstract

A method for performing a lockout-tagout procedure includes reading, by a sensor of a portable device, a location tag positioned at a location or on a device that an electronic lock is associated with to acquire a location identifier; acquiring, by a communication device of the portable device, audit data from the electronic lock regarding at least one of a lock event or an unlock event of the electronic lock; and at least one of transmitting, by the communication device of the portable device, the audit data and the location identifier to a remote server configured to provide for determination of compliance with the lockout-tagout procedure using the audit data and the location identifier; or interpreting, by a processing circuit of the portable device, the audit data and the location identifier to determine at least one of the lock event or the unlock event is part of the lockout-tagout procedure.

First claim

The invention claimed is:

1. A method for performing a lockout-tagout procedure, comprising:
reading, by a sensor of a portable device, a location tag positioned at a location or on a device that an electronic lock is associated with to acquire a location identifier;
acquiring, by a communication device of the portable device, audit data from the electronic lock regarding at least one of a lock event or an unlock event of the electronic lock as part of the lockout-tagout procedure; and
at least one of:
(i) transmitting, by the communication device of the portable device, the audit data and the location identifier to a remote server configured to provide for determination of compliance with the lockout-tagout procedure using the audit data and the location identifier; or
(ii) interpreting, by a processing circuit of the portable device, the audit data and the location identifier to determine the at least one of the lock event or the unlock event is part of the lockout-tagout procedure.

2. The method of claim 1 , wherein the sensor includes an optical recognition sensor configured to read at least one of a barcode or a quick response code of the location tag.

3. The method of claim 1 , wherein the sensor includes an RFID reader configured to read a RFID device of the location tag.

4. The method of claim 1 , further comprising storing, by the electronic lock, the audit data in response to the at least one of the lock event or the unlock event.

5. The method of claim 1 , further comprising recalling, by the processing circuit of the portable device from memory of the portable device, the lockout-tagout procedure based on the location identifier.

6. The method of claim 5 , further comprising determining, by the processing circuit of the portable device, whether the lockout-tagout procedure has been complied with based on the audit data.

7. The method of claim 6 , providing, by the portable device, an indication of compliance for display to an operator.

8. The method of claim 1 , further comprising receiving, by the communication device of the portable device, an indication of compliance with the lockout-tagout procedure from the remote server based on the location identifier and the audit data transmitted to the remote server.

9. The method of claim 8 , further comprising providing, by the portable device, the indication of compliance for display to an operator.

10. The method of claim 1 , further comprising receiving, by the communication device of the portable device, the lockout-tagout procedure from the remote server based on the location identifier transmitted to the remote server.

11. The method of claim 10 , further comprising determining, by the processing circuit of the portable device, whether the lockout-tagout procedure has been complied with based on the audit data and the lockout-tagout procedure received from the remote server.

12. The method of claim 11 , providing, by the portable device, an indication of compliance for display to an operator.

13. A method for performing a lockout-tagout procedure, comprising:
reading, by a sensor of a portable device, a plurality of location tags to acquire a plurality of location identifiers, each of the plurality of location tags positioned at a respective location or on a respective device that a respective electronic lock is associated with;
acquiring, by a communication device of the portable device, audit data from a plurality of electronic locks regarding at least one of a lock event or an unlock event of each of the plurality of electronic locks as part of the lockout-tagout procedure;
transmitting, by the communication device of the portable device, the plurality of location identifiers and the audit data to a remote server; and
facilitating, by the remote server, a determination that lock-tagout procedure was completed based on at least one of (i) all of the location tags for the lockout-tagout procedure being read, (ii) the plurality of location tags being read in a correct order according to the lockout-tagout procedure, or (iii) the audit data indicating that the plurality of electronic locks were locked or unlocked in a correct order according to the lockout-tagout procedure.

14. The method of claim 13 , wherein the sensor includes at least one of (i) an optical recognition sensor configured to read at least one of a barcode or a quick response code of the plurality of location tags or (ii) an RFID reader configured to read a RFID device of the plurality of location tags.

15. The method of claim 13 , further comprising providing, by the portable device, an error notification in response receiving an indication that the lockout-tagout procedure was not complied with.

16. The method of claim 13 , further comprising storing, by the plurality of electronic locks, the audit data in response to the at least one of the lock event or the unlock event.

17. A method for performing a lockout-tagout procedure, comprising:
reading, by a sensor of a portable device, a location tag positioned at a location or on a device that an electronic lock is associated with to acquire a location identifier;
acquiring, by a communication device of the portable device, audit data from the electronic lock regarding at least one of a lock event or an unlock event of the electronic lock as part of the lockout-tagout procedure;
transmitting, by the communication device of the portable device, the audit data and the location identifier to a remote server;
recalling, by the remote server, the lockout-tagout procedure based on the location identifier;
facilitating, by the remote server, a determination that the lockout-tagout procedure has been complied with based on the audit data and the recalled lockout-tagout procedure; and
providing, by the remote server, an error notification to the portable device in response to (i) the remote server determining or (ii) the remote server receiving an indication that the lockout-tagout procedure was not complied with.

18. The method of claim 17 , wherein the sensor includes at least one of (i) an optical recognition sensor configured to read at least one of a barcode or a quick response code of the location tag or (ii) an RFID reader configured to read a RFID device of the location tag.

19. The method of claim 17 , further comprising providing, by the portable device, a warning in response to receiving the error notification.

20. The method of claim 17 , further comprising storing, by the electronic lock, the audit data in response to the at least one of the lock event or the unlock event.
