Abstract

An RFID tag reading system affixed to a machine bearing housing is provided. The reading system includes a mobile data collector having an RFID reader for reading a unique identity of the RFID tag, an magnet electro-mechanically connected to the mobile data collector and a magnet mounting pad fixed to the machine housing. The magnet mounting pad having a ferromagnetic contact body for housing the magnet mounting pad and an RFID antenna disposed within the RFID tag for transmitting a unique identity of the RFID tag. The RFID tag is disposed within the ferromagnetic contact body. The magnet is magnetically connected to the magnet mounting pad. The mobile data collector automatically reads the unique RFID tag identity transmitted from the antenna of the RFID tag when the combination mobile data collector and magnet are placed onto the RFID mounting pad.

Claims

1. A magnet mounting pad affixed to a machine housing, the magnet mounting pad comprising;

a ferromagnetic contact body for housing the magnet mounting pad, the ferromagnetic contact body comprising a well;

an active RFID tag having a unique identity and disposed within an unexposed portion of the well of the ferromagnetic contact body; and

an RFID antenna integral to the active RFID tag,

wherein the RFID antenna transmits the unique identity of the active RFID tag when a magnet of a mobile data collector is magnetically connected to the magnet mounting pad without requiring the mobile data collector to energize the active RFID tag,

wherein the RDIF antenna is disposed within an exposed portion of the well of the ferromagnetic contact body, and

wherein the RFID antenna comprises one of an RFID spiral antenna and a RFID wound inductor antenna.

2. The magnet mounting pad according to claim 1, wherein the ferromagnetic contact body further provides a disk shaped contact body having a bottom portion, a side portion and a top portion.

3. The magnet mounting pad according to claim 2, wherein the active RFID tag is one of sealed within the well and epoxied in place.

4. The magnet mounting pad according to claim 1, wherein the active RFID tag is sealed within the well with a potting material.

5. The magnet mounting pad according to claim 1, wherein the active RFID tag comprises a metal mount.

6. The magnet mounting pad according to claim 1, wherein the mounting pad is affixed to the machine housing by being one of epoxied and studded together.

7. The magnet mounting pad according to claim 1, wherein the machine housing further comprises a machine bearing housing.

8. The magnet mounting pad according to claim 1, wherein the active RFID tag is associated with a Point ID.

9. The magnet mounting pad according to claim 8, wherein the Point ID is preloaded into the active RFID tag prior to shipment.

10. An RFID tag reading system in conjunction with a piece of rotating equipment, the reading system comprising:

a mobile data collector having an RFID reader for reading a unique identity of an active RFID tag;

an magnet electro-mechanically connected to the mobile data collector; and

a magnet mounting pad fixed to a machine housing, the magnet mounting pad comprising;

a ferromagnetic contact body for housing the magnet mounting pad, the ferromagnetic contact body comprising a well;

the active RFID tag having a unique identity and disposed within an unexposed portion of the well of the ferromagnetic contact body; and

an RFID antenna integral to the active RFID tag,

wherein the RFID antenna transmits the unique identity of the active RFID tag and is disposed within an exposed portion of the well of the ferromagnetic contact body,

wherein the RFID antenna comprises one of an RFID spiral antenna and a RFID wound inductor antenna,

wherein the magnet is magnetically connected to the magnet mounting pad,

wherein the mobile data collector automatically reads the unique RFID tag identity transmitted from the RFID antenna of the active RFID tag when the combination mobile data collector and magnet with its mounting magnet are placed onto the RFID mounting pad to form a single system without requiring the mobile data collector to energize the active RFID tag, and

wherein the RFID tag ID is used by the data collection device to retrieve POINT ID and POINT setting information and automatically initiate measurements comprising vibration and temperature measurements.
