1. A monitoring system for monitoring a time period of a locking state of a rotor of a wind turbine, comprising:
at least one motion sensor,
at least one computing unit, wherein the at least one computing unit is configured to receive at least one motion measurement from the at least one motion sensor and wherein the at least one computing unit is configured to determine whether the rotor may remain in the locking state or the rotor should be unlocked based on the at least one motion measurement; and
a signaling system configured for outputting a signal based on the determination of the at least one computing unit, wherein the signaling system is configured such that the signal is visual and/or acoustical, and wherein the signaling system is configured for outputting the signal with the rotor remaining in the locking state.
