Abstract

The present invention relates to a transmission belt providing a belt member, and at least one RFID tag attached to the belt member, the at least one RFID tag including an integrated circuit, and an antenna connected to the integrated circuit for transmitting a signal indicative of a state of the transmission belt. The signal indicative of the state of the transmission belt is determined on the basis of a current deflection of the antenna.

First claim

The invention claimed is:

1. A transmission belt comprising:
a belt member, and
a first RFID tag and a second RFID tag attached to the belt member, each of the first and second RFID tags comprising:
an integrated circuit, and
an antenna connected to the integrated circuit for transmitting a signal indicative of a state of the transmission belt, wherein
the signal indicative of the state of the transmission belt is determined on the basis of a current deflection of the antenna,

wherein the first RFID tag is a passive RFID tag and the second RFID tag is an active RFID tag, and
wherein the belt is made from rubber and metal wires to provide strength.

2. The transmission belt according to claim 1 , wherein the state is a state of elongation of the transmission belt.

3. The transmission belt according to claim 1 , wherein the first and second RFID tags are configured to transmit the signal while the transmission belt is in operation.

4. The transmission belt according to claim 1 , wherein the transmission belt further comprises a Bluetooth transmitter configured to transmit at least part of the signal wirelessly, and a battery configured to power the Bluetooth transmitter, and optionally configured to power the first and second RFID tags.

5. A condition monitoring arrangement for monitoring a state of a transmission belt, the arrangement comprising:
a transmission belt having a belt member, and a first RFID tag and a second RFID tag attached to the belt member,
each of the first and second RFID tags comprising:
an integrated circuit, and
an antenna connected to the integrated circuit for transmitting a signal indicative of a state of the transmission belt,
wherein the first RFID tag is a passive RFID tag and the second RFID tag is an active RFID tag,
wherein the belt is made from rubber and metal wires to provide strength,
wherein the signal indicative of the state of the transmission belt is determined on the basis of a current deflection of the antenna, wherein

the arrangement further comprises at least one receiver for receiving the signal transmitted from the transmission belt.

6. A method for issuing a signal indicative of the state of a transmission belt, wherein the belt is made from rubber and metal wires to provide strength, the belt providing a belt member, and a first RFID tag and a second FRID tag attached to the belt member, the first and second RFID tags including an integrated circuit, and an antenna connected to the integrated circuit for transmitting a signal indicative of a state of the transmission belt, the first RFID tag being a passive RFID tag and the second RFID tag being an active RFID tag, the method comprising:
determining the state of the transmission belt on the basis of a current deflection of the antenna, and
issuing the signal.

7. The method for condition monitoring a transmission belt issuing a signal according to claim 6 , the method comprising:
receiving the signal by using a receiver, and
comparing the signal with a predetermined signal set.

8. The method for condition monitoring a transmission belt according to claim 7 , further comprising:
notifying an operator if the signal is outside a predetermined signal set.
