Torque measuring apparatus, torque monitoring system, and torque monitoring method

A torque measuring apparatus, comprising:

• a rotating body having one end fixedly connected to a driving shaft and a second end fixedly connected to a driven shaft;
• a sensor unit outputting a torque signal corresponding to a torque delivered from the driving shaft;
• and
• a Bluetooth unit transmitting the torque signal output from the sensor unit through Bluetooth communication.

A torque monitoring system, comprising:

• a rotating body having one end fixedly connected to a driving shaft and a second end fixedly connected to a driven shaft;
• a sensor unit outputting a torque signal corresponding to torque delivered from the driving shaft;
• a Bluetooth unit including a Bluetooth transmitter receiving the torque signal output from the sensor unit and transmitting the received torque signal through Bluetooth communication, and a Bluetooth receiver receiving the torque signal transmitted from the Bluetooth transmitter;
• and
• a monitoring unit connected to the Bluetooth receiver and monitoring the received torque signal.

A torque monitoring method, comprising:

• measuring torque delivered from a driving shaft to a driven shaft at predetermined period and generating a corresponding electric signal;
• generating a torque signal based on the electric signal;
• wirelessly transmitting the torque signal through Bluetooth communication;
• and
• monitoring the torque signal received through the Bluetooth communication.
