Abstract
A transmission belt includes a belt member, and at least one sensor attached to the belt member that is configured to measure a parameter indicative of a state of the transmission belt. A transmitter is attached to the belt member and configured to transmit a signal indicative of the state of the transmission belt to a receiver. The transmission belt includes a power system configured to provide power to the at least one sensor and/or the transmitter, and the power system includes a power source and an energy converter. The energy converter is configured to receive energy, convert the received energy to electrical energy and provide the electrical energy to the power source.
Claims11
A method for providing electrical power to one or more sensors and/or a transmitter for issuing a signal indicative of a state of a transmission belt, the transmission belt comprising:
- a belt member,
- at least one sensor mounted in or on the belt member for measuring a parameter indicative of a state of the transmission belt, the at least one sensor including an antenna, and the parameter indicative of the state of the transmission belt being a current deflection of the antenna,
- a transmitter mounted in or on the belt member for transmitting a signal indicative of the state of the transmission belt, and
- a power system mounted in or on the belt member for providing electrical power to the at least one sensor and/or the transmitter, the power system comprising a power source and an energy converter, wherein the energy converter is configured to produce an electric current from kinetic energy of the belt and supply the electric current to the power source,
- the method comprising:
- driving the transmission belt,
- using the energy converter to produce the electric current from the kinetic energy of the driven transmission belt,
- providing the electric current from the power system to the at least one sensor and/or transmitter,
- determining the state of the transmission belt from the parameter, and
- issuing the signal indicative of the state of the transmission belt.
A transmission belt, comprising:
- a belt member,
- at least one sensor attached to the belt member and configured to measure a parameter indicative of a state of the transmission belt,
- a transmitter attached to the belt member and configured to transmit a signal indicative of the state of the transmission belt to a receiver, and
- a power system configured to provide power to the at least one sensor and/or the transmitter,
- wherein the power system includes an electrical storage device electrically connected to an energy converter,
- wherein the energy converter is configured to produce an electric current from kinetic energy of the belt member,
- wherein the at least one sensor includes an antenna, and
- wherein the parameter indicative of the state of the transmission belt is a current deflection of the antenna.
