Abstract

A system for monitoring a lockout condition of a component includes a lockout device, a lock unit, and a reader. The lockout device is moveable between a lockout condition blocking operation of the component and an access condition permitting operation of the component. The lock unit is configured to be secured to a lockout interface of the lockout device to secure the lockout device in the lockout condition. One of the lockout device and the lock unit includes a communication module configured to communicate a data signal including an identification code identifying the one of the lockout device and the lock unit. The reader is remote from the one of the lockout device and the lock unit, and is configured to receive the data signal at least when the lockout device is assembled with the component and the lock unit is secured to the lockout interface of the lockout device.

Claims

1. A lockout device comprising:

a housing configured to be assembled with a component to be locked out;

an apertured member defining at least a first lock aperture, the apertured member being moveable with respect to the housing between a lockout condition blocking operation of the component and an access condition permitting operation of the component, wherein the first lock aperture is sized to receive a shackle of a padlock therethrough when the apertured member is in the lockout condition, such that the padlock shackle secures the apertured member in the lockout condition, the padlock being separate from the lockout device; and

a communication module disposed in the housing and configured to wirelessly communicate a first data signal including an identification code identifying the lockout device.

2. The lockout device of claim 1, wherein the first data signal further includes data indicating a condition of the lockout device.

3. The lockout device of claim 2, wherein the condition of the lockout device comprises at least one of the lockout condition and the access condition.

4. The lockout device of claim 2, wherein the condition of the lockout device comprises a low battery condition.

5. The lockout device of claim 1, wherein the communication module comprises an RFID tag.

6. The lockout device of claim 1, wherein the communication module comprises an active RFID tag.

7. The lockout device of claim 1, wherein the communication module comprises a passive RFID tag.

8. The lockout device of claim 1, wherein the communication module is configured to provide wireless communication utilizing one or more of WiFi (IEEE 802.11 communication protocol), ZigBee (IEEE 802.15 communication protocol), Radio Frequency (RFID) communication, infrared transmission, Near Field Communication (NFC), and Bluetooth communication.

9. The lockout device of claim 1, wherein the communication module comprises a reader configured to receive a second data signal.

10. The lockout device of claim 9, wherein the second data signal includes a second identification code identifying a padlock proximate to the lockout device.

11. The lockout device of claim 9, wherein the second data signal includes a second identification code identifying a padlock secured through the first lock aperture of the lockout device.

12. The lockout device of claim 9, wherein the first data signal includes data obtained from the second data signal.

13. A system for monitoring a lockout condition of a component, the system comprising:

a lockout device comprising a housing configured to be assembled with a component to be locked out an apertured member defining at least a first lock aperture, the apertured member being moveable with respect to the housing between a lockout condition blocking operation of the component and an access condition permitting operation of the component, wherein the first lock aperture is sized to receive a shackle of a padlock therethrough when the apertured member is in the lockout condition, such that the padlock shackle secures the apertured member in the lockout condition, the padlock being separate from the lockout device; and

a first communication module disposed in the housing and configured to wirelessly communicate a first data signal including an identification code identifying the lockout device; and

a communication device including a second communication module operable to be in wireless communication with the first communication module.

14. The system of claim 13, wherein the communication device comprises a padlock, wherein the second communication module is operable to be in wireless communication with the first communication module when a shackle of the padlock is secured through the first lock aperture of the lockout device.

15. The system of claim 13, wherein the first data signal further includes data indicating a condition of the lockout device.

16. The system of claim 13, wherein the second communication module is configured to receive the first data signal.

17. The system of claim 13, wherein the second communication module is configured to wirelessly transmit a second data signal.

18. The system of claim 17, wherein the second data signal includes data obtained from the first data signal.

19. The system of claim 13, wherein the second communication module is configured to transmit a second data signal to the first communication module.

20. A method of monitoring lockout procedures, the method comprising:

providing a lockout device comprising a housing configured to be assembled with a component to be locked out an apertured member defining a lock aperture, the apertured member being moveable with respect to the housing between a lockout condition blocking operation of the component and an access condition permitting operation of the component;

inserting a shackle of a padlock through the lock aperture, and manually moving the shackle to a locked position with a lock body of the padlock to secure the padlock to the lockout device in a lockout condition, the lockout device being separate from the padlock; and

using a communication device, wirelessly receiving a data signal generated by a first communication module disposed in the housing of the lockout device, and received by a second communication module disposed in the communication device, the data signal including data identifying at least one of an identification code of the lockout device, an identification code of the padlock, a condition of the lockout device, and a condition of the padlock.
