Provided is a state monitoring system that monitors a state of an apparatus provided in a wind turbine, including a wireless measuring unit including a sensor provided to the apparatus, and a data collection. The wireless measuring unit includes a memory storing measured data obtained from the sensor, and a wireless communication unit transmitting the measured data obtained from the sensor to the data collection device. When the data collection device has not been able to receive the measured data from the wireless measuring unit, the data collection device requests the wireless measuring unit to retransmit the measured data.

State monitoring system

A condition monitoring system that diagnoses an abnormality of an apparatus provided in a wind turbine includes a monitoring apparatus including a sensor provided for the apparatus, a monitoring-side control apparatus that sets a threshold value to be used by the monitoring apparatus for diagnosing the abnormality of the apparatus, and diagnoses the abnormality of the apparatus based on the threshold value, and a monitoring terminal that monitors a condition of the apparatus. The condition monitoring system can correctly diagnose an abnormality of the apparatus provided in the wind turbine.
