  • Machine system including wireless sensor
    Patent number: 9321178
    Abstract: A machine system including a sensor unit detecting periodically an acceleration at a tip part of a movable member, a data acquisition unit acquiring first time-series data of the acceleration at the tip part of the movable member corresponding to sensor signal received via a wireless signal path, a data calculation unit configured to calculate second time-series data corresponding to the first time-series data based on a driving command of the motor, a delay time calculation unit calculating a delay time of the first time-series data with respect to the second time-series data according to a degree of correlation between first time-series data and the second time-series data, and a correction unit correcting the first time-series data based on the delay time.
