Abstract
An industrial roll includes: a substantially cylindrical shell having an outer surface; a polymeric cover circumferentially overlying the shell outer surface; and a sensing system. The sensing system includes: a plurality of sensors embedded in the cover, each sensor configured to sense a data parameter; and a plurality of wireless transceivers, each transceiver connected to a respective sensor and embedded in the cover adjacent thereto. Each wireless transceiver is configured to transmit data signals from the respective sensor. Related methods and systems are also discussed.
Claims66
An industrial roll, comprising:
- a substantially cylindrical shell having an outer surface;
- a polymeric cover circumferentially overlying the shell outer surface;
- a sensing system comprising:
- a plurality of sensors embedded in the cover, each sensor configured to sense a data parameter;
- and
- a plurality of wireless transceivers, each transceiver connected to a respective sensor and embedded in the cover adjacent thereto for transmitting data signals from the sensor;
- a wireless receiver operatively associated with the plurality of wireless transceivers for receiving data signals from the wireless transceivers;
- and
- a remote processor operatively associated with the receiver that processes the data signals conveyed thereby;
- a plurality of power sources, each power source connected to a respective sensor and wireless transceiver and embedded in the cover adjacent thereto, wherein each power source comprises one of a battery, a rechargeable battery, and a capacitor;
- and
- a charging system for recharging each power source, wherein the charging system comprises:
- a fixed member that spans a length of a roll;
- and
- a plurality of wireless chargers attached along a length of the member, each charger configured to recharge a power source using inductive coupling during roll operation.
A method of collecting signal data in an industrial roil with a cover having a plurality of sensors embedded in the cover and configured to sense data parameters, comprising:
- providing a plurality of wireless transceivers, each transceiver connected to a respective sensor and embedded in the cover adjacent thereto;
- and
- transmitting a data signal from a sensor to a processor with a respective wireless transceiver;
- transmitting power to the plurality of sensors and wireless transceivers with a plurality of power sources, each power source connected to a respective sensor and wireless transceiver and embedded adjacent thereto, wherein each power source comprises one of a battery, a rechargeable battery, and a capacitor;
- and further comprising recharging each power source using a wireless charging system, wherein recharging comprises:
- providing a fixed member having a plurality of wireless chargers that spans a length of a roll;
- and
- recharging the power sources with the wireless chargers during roll operation using inductive coupling.
A system for determining operating parameters in an industrial roll, comprising:
- a plurality of sensors embedded in a polymeric cover circumferentially overlying an outer surface of the roll, each sensor configured to sense a data parameter;
- a plurality of wireless transceivers, each transceiver connected to a respective sensor and embedded in the cover adjacent thereto for transmitting data signals from the sensor;
- a wireless receiver operatively associated with the plurality of wireless transceivers for receiving data signals from the wireless transceivers;
- a remote processor operatively associated with the receiver that processes the data signals conveyed thereby;
- a plurality of power sources, each power source connected to a respective sensor and wireless transceiver and embedded in the cover adjacent thereto;
- and
- a charging system for recharging each power source, wherein the charging system comprises:
- a fixed member that spans a length of a roll;
- and
- a plurality of wireless chargers attached alone a length of the member, each charger configured to recharge a power source using inductive coupling during roll operation.
